Unit 1: Being Human

The mind body problem

What is the problem? 

• Philosophers have found the relationship between the mind and the body to be problematic. 

• Humans have both a body and a mind. 

• It is not difficult to describe bodies as they all have physical properties similar to any physical object, human bodies are similar to complex machines. 

• When we try to describe our mind as it doesn’t have any physical attributes, describing it as a “grey organic mass” would be describing the brain but not the mind. However, we can describe our minds using our mental states. 

The mind allows us to: 

• To perceive, small and touch the world 

• To have self awareness

• To have dreams and hopes

• To feel emotions 

• To store and retrieve memories 

• To reason about the world 

• To communicate with others 

The human mind and bodies are often connected to each other

• Physical (like a cut on the finger) can produce mental states (like pain). 

• Mental states like feeling embarrassed can produce physical states like blushing. 

Substance Dualism 

Descartes theory

• From his famous quote “Dictum cogito, ergo sum” (I think, therefore I am). 

• He developed a theory of mind as an immaterial, unextended substance that engages in various activities or undergoes various states such as rational thought, imagining, feeling and willing. 

Proof 1 

Descartes argument from doubt 

1. I can doubt that my body exists 

2. I cannot doubt that I exist 

3. Therefore - I (my mind - ‘I am a thinking thing’) must be distinct (separate) from my body. 

Proof 2  

Argument from indivisibility 

1. The body is divisible into parts 

2. The mind is not divisible into parts

3. Therefore, my mind is different from my body 

Proof 3 

The mind can exist independently for the argument from irreducibility 

1. If substance dualism is false, then my mind cannot exist independently from my body 

2. My mind can exist independently from my body 

3. Therefore substance dualism is true

The gateway experience: investigating to separate the mind from their body 

The three main physicalist theories of the mind 

Behaviourism 

• Behaviourism, which translates to “mental states” defines a tendency to behave in a certain way. Our emotions or sensations are learned responses to the stimuli of the world. And this has nothing to do with mental states. 

• Gilbert Ryle uses conditional statements to do this. Eg. A person is thirsty, if there is water available, then that person would drink water. 

• In relation to the Mind and Body debate: the idea that the mind is redundant and that there is only the body. 

Three Parts to Behaviourism

• Psychological behaviourism 

  • Seek statements that can be verified, Psychological behavior can be verified through observation. 

  • Focuses on how organisms form association (cause and effect relationships) in the world in response to stimuli - the environment and how this is reinforced.

  • Disregards mental activities

• Logical/Analytical behaviourism 

  • The idea is that mental states are actually behavioural tendencies. 

    • Example: to believe in something (like the time of your appointment) is a tendency, and it has nothing to do with mental substance. 

  • But cause and effect are distinct, just because you know when the appointment is, doesn’t mean it will be the cause of your arrival. 

    • Example. Mental states like “John loves Lucy” cannot be determined whether it is true or false but behaviour can be like “John hugs Lucy and tells her he loves her”. 

• Methodological behaviourism 

  • Mental states do not add to the understanding of behaviourism in organisms. It is a private entity. Making it unsuitable for empirical study.  

  • Seeks to predict the response based on the stimuli, or when given the reaction. To predict the stimulus that has given rise to it. 

Criticism to behaviourism 

• Behaviourism was criticized for its neglect of the existence of inner mental states such as beliefs, desires, sensations and emotions. 

• The theory is too simple and it undermines the complexity of human behaviours by reducing our mental process into only simple stimulus-response connections that this theory fails to enrich the human mind.

Functionalism 

• Another theory of the nature of mental states, associated with the ontological and metaphysical theory. Instead of focusing on the materialistic aspect of the mind, for example, what it is made of, it focuses on its function (in the terms of inputs and outputs) 

  • Example: when getting injured, the role of the mind is to feel pain. This condition can only be met by creatures of internal states, where the role of their minds is to feel emotions. 

  • Similar to the relationship between a robot and a programmer,  a computer may not have a nervous system but if the programmer programmed the robot to run away from fear, then that is exactly what they will do. This analogy can be applied to humans. 

• Materialistic Solution to the mind and body problem  

  • Some aspects of the mental state could be associated with the physical state.

  • Supports the idea that the mental causation is heavily under the physical causation.

  • Consciousness and the mind cannot be explained by non-physical matter as the mind is essentially programmed.

  • The mind can be replicated with AI. 

Identity Theory

• The mind is identical to the states and processes of the brain, experiences are brain processes not correlation. 

• One’s identity is not qualitative but quantitative so it has no relation to the personal identity. These brain processes are also referred to as “Qualia”.

• Another name for identity theory is reductive materialism, that our mental states are just our brain states. 

The relation to the mind and body problem 

• The mind is part of the physical body, meaning that “mental states'' are the same as “brain states”. 

• A more materialistic approach as well, as there are more “laws” used to define the mind. 

The Qualia

• Lrving Lewis defined qualia as properties of sense - data themselves, intrinsic non-representational properties. However, this is not the same as just properties. 

• Example: something like being blue is not the same as someone experiencing blue. More personal approach. We might not all experience the same type of blue. 

Daniel Dennett’s four properties of qualia 

• Ineffable - cannot be communicated or apprehended by any means other than direct experiences   

• Intrinsic - Non-relational properties, do not change depending on the experience’s relation to other things. 

• Private - All interpersonal comparisons of qualias are systematically impossible   

• Directly or immediately reprehensible by consciousness - to experience a quale is to know one experience a quale, and to know all there is to know about that quale.   

Descartes conceivability argument 

• I have a clear idea of my mind as a thinking thing that is not extended in space. 

• I have a clear idea of my body as a non-thinking thing that is extended in space. 

• Anything I conceive clearly is something that god could create. 

• So it is possible for the mind and body to exist independently of each other. 

Responses

• Mind without body is inconceivable: 

  • Behaviourism states that to have mental states is to have behavioural dispositions, which is to be disposed to move your body in certain ways. 

  • This can’t be done without a body. 

  • So a mind without a body is inconceivable. 

• The things that are conceivable may not be physically possible: 

  • Just because something is logically possible (meaning that it doesn’t involve a logical contradiction) doesn’t mean it is physically possible 

  • Example: just because jumping onto the moon from Earth might be physically impossible but there is no logical contradiction in this idea. 

  • Similarly it is logically possible for a mind to exist independently of a body, this doesn’t automatically mean such a thing is physically possible. 

• Masked man fallacy:

  • Inference to Descartes's argument is that: 

    • I conceive of Batman as a caped crusader

    • I conceive of Bruce Wayne as a billionaire who is not a caped crusader 

    • Therefore Batman is not Bruce Wayne. 

  • Idea that things that are conceivable tells us nothing about how things are in reality. 

  • Just because you have an idea that the mind and body are separate things, this doesn’t mean they are separate things. 

Descartes’s Divisibility argument 

• My body is divisible 

• My is not divisible 

• Therefore my mind and body are separate things 

Responses

• The mind is divisible 

  • In cases of mental illness, a mind would be able to literally be divided, for example, someone with a personality disorder.

  • Another example is for a person who has literally had their brain cut in half. A corpus callosotomy is a surgical procedure for epilepsy where the main connection between the left and right hemispheres of the brain is severed. 

• Not everything that is physical is divisible 

  • Mind could be just be an invisible type of physical substance 

  • Physical bodies like the limbs are definitely divisible but if you keep dividing it, you might eventually reach a point where you cannot divide it any further as it would just be left with lots of atoms or reach a form of physical substance that is indivisible 

  • Descartes doesn’t prove that the mind isn’t indivisible

  • Descartes doesn’t prove that the body is divisible. 

Problems for Substance Dualism 

The problem of other minds 

• The question of what kind of evidence is available to prove that the mind exists within other people, because if substance dualism is true and the mind and body are actually two separate pieces, then it’s possible that some people are existing without a mind. 

 Mill’s argument from analogy 

• English philosopher John Stuart Mill responds to this with an analogy between his own mind and the minds of others:

1. I have a mind 

2. My mind causes my behaviour 

3. Other people have bodies and behave similarly to me in similar situations 

4. By analogy their behaviour has the same type of cause as my behaviour: a mind 

5. Therefor, other people have minds 

• However, this theory can’t be applied to everyone as it’s the same thing as saying “that dog has three legs so all dogs have three legs”. 

Other minds are the best explanation 

• Another response accepts that we can’t observe or prove the existence of minds, but says we should believe in their existence anyway since it is the best explanation. 

• One reason why is due to their explanatory and predictive power, if other people have minds, it would make sense why they behave the way that they do. 

Causal interaction 

• How mental things can casually interact with physical things when they are supposed to be two separate things. 

  • Example: If I’m feeling hungry (mental state) it might cause me to move my body (physical thing to the fridge to get food). 

• How does information of a non-physical thing transfer over tinto the physical world and cause things to happen? 

The conceptual interaction problem 

• The objection proof was created by Descartes’ own student, Princess Elisabeth of Bohemia: 

1. Physical things only move if they are pushed 

2. Only something that is physical and can touch the thing that is moved can exert such e force 

3. But the mind is not physical, so it can’t touch the body

4. Therefore , the mind cannot move the body. 

• 4 is definitely wrong so there is something else in the argument that made this completely wrong, the most likely one is 3 which implies that the mind is actually physical. 

The empirical interaction problem 

• The second law of thermodynamics (in physics) states that energy cannot be created nor destroyed but can be transferred from one state to another. 

• This means that energy cannot be created from anything outside of the physical universe and affect things within it. 

• Substance dualism says that the mental is supposedly something that is outside the physical universe 

• So therefore substance dualism will be false. 

Property dualism

• Presents the idea that there is that some minds have non-physical properties. 

• It's not saying that the mind is completely non-physical but this is different from physicalism in the property dualists believe a complete description of the physical universe would not be a complete description of the entire universe, they believe that a complete description if the universe would miss out qualia. 

• According to property dualism, it is possible for two physically identical things to be different in some way. More specifically, property dualism states that it's possible that two physically identical things could have different mental properties ‘ different qualia. 

Supervenience 

• The relationship between two kinds of things. 

• If something supervenes on something else, then it is dependent on that thing. 

David Chalmers: The Zombie Argument 

• A philosophical zombie is a person who is physically and functionally identical to an ordinary human except they don’t have any qualia. Such zombies are conceivable. Similar to Descartes conceivability argument: 

• Philosophical zombies are conceivable 

• If philosophical zombies are conceivable then philosophical zombies are metaphysically possible 

• If philosophical zombies are metaphysically possible then qualia are non-physical 

• If qualia are non-physical then property dualism is true 

• Therefore property dualism is true. 

Responses to the Zombie Argument 

• Zombies are not conceivable 

• Zombies are not (metaphysically possible) 

Problems with property dualism

Introspective self-knowledge

• The idea of asking: How do we know about our own mental states? 

  • If epiphenomenalism is true, qualia have no causal effects. 

  • If qualia have no causal effects, then knowledge of mental states is impossible. 

  • But knowledge of mental states is possible (e.g. I can know “I am in pain”). 

  • So, epiphenomenalism must be false. 

The phenomenology of mental life 

• In addition to causing knowledge, qualia can also cause other things. 

  • Example: if someone feels pain, this may cause them to feel sad. 

• If epiphenomenalism is correct, then qualia have no causal powers.

• Qualia obviously do cause other mental states so epiphenomenalism must be false. 

Evolution

• Evolution is that genetic mutations occur randomly, these genes often give benefit for survival. 

  • Example: long necks cause giraffes not to die of starvation. The causal effects of long necks genes clearly explain why giraffes have long necks. 

• But if epiphenomenalism is true then there would be no evolutionary benefit to having qualia because epiphenomenal qualia doesn’t have any causal effect. 

• So if the minds are the product of evolution, it would suggest that epiphenomenalism is false: qualia does have some useful casual role, otherwise we wouldn’t have evolved it. 

Monism

The two types of Monism 

• Materialism: The belief that nothing exists apart from the material world (ie. physical matter like the brain). Materialist psychologists generally agree that consciousness (the mind) is the function of the brain. Mental processes can be identified with purely physical processes in the central nervous system, and human beings are just complicated physiological organisms, no more than that. 

• Phenomenalism: Also known as subjective idealism, believes that physical objects and events are reducible to mental objects, properties and events. Ultimately, only mental objects like the mind exist. Irish philosopher Bishop Berkeley claimed that we think of our body as merely the perception of the mind. 

Free will and determinism

• Libertarianism: the theory that according to which human beings are free agents. Although the material world around us is determined by the laws of nature, human choices are subjected to these laws. Libertarians recognise that there are certain limitations due to the laws of nature like gravity as well as their upbringings. However, they still maintain the idea that freedom is always exercised. 

Key philosophers for libertarianism: 

• Rene Descartes: He believed that the mind (reference to substance dualism) is not confined to the rules of the physical world and is where we can exercise free will. Though his stance on free will has been debated over as his statements were brief and not in-depth enough to figure out what exactly he meant

• William James: Believed that determinism is contradictory to our moral values 

• Robert Kane: Modern-day philosopher who supports libertarianism. 

Criticisms 

• Free will and determinism: The compatibility with determinism is likely one of the major criticisms of libertarianism, if determinism is true that means all human actions are all predetermined and there's no room for genuine free will. 

• Another factor that challenges libertarianism is the Social Contract Theory, every individual has responsibilities and obligations towards each other and as a collective society if libertarianism is truly the only theory then the societal rules and institutions will be deemed unnecessary 

• Many argue that libertarianism is too simple of a theory although people may have the free will to make their own decisions this neglects the factor of the importance of how society, history and culture shape the person resulting in them generally systematically making a “predictable” decision. 

Strengths

• Libertarian appeals to the quantum indeterminate theory, which is the idea that the causes of some events are deterministic or random. This proves that physical aspects like the mind and it’s process to make decisions is not fully deterministic. 

• Libertarianism also rejects the concept of fatalism which is the belief that all events are inevitable. Whereas determinism accepts this, undermining our sense of responsibility and agency. 

• Unlike libertarianism, determinism threatens the ideation of a unitary self being the source of its own actions, which is essential for personal identity and autonomy.

Determinism: 

• Determinism is the idea that everything has a cause or a set of causes, what happened had to happen instead. 

• This can refer to natural events and the laws of nature but also support the argument for the existence of God as determinism would prove that God is omniscient (all-knowing) and can determine all your actions. 

• Determinists believe that our choices do not really come from our free will but from a series of causes that made them inevitable and theoretically predictable. 

Types of Determinism

Scientific determinism 

• It is the perspective that defines the results of science and scientific behaviour, saying that all events in the universe are ultimately determined by causal laws of nature. 

• The philosopher who first influenced this idea was Pierre-Simon Laplace, who proposed a hypothetical “demon” that could predict the future state of the universe with perfect accuracy if they knew the precise positions and velocities of all the molecules in the universe. 

• After Issac Newton’s discovery of calculus and the laws of classical mechanics, it made the assumptions of nature much more predictable. 

  • Example: the conservation of energy and the unchanging speed of time. Viewing that the universe is entirely mechanistic. 

Criticisms

• Freewill: If all human actions could be calculated it raises the question of whether we humans have genuine freedom. Determinism could undermine the point of moral responsibility, if everything was already determined then praises and blame would be redundant.    

• Quantum mechanics: The theory that describes the behaviour of particles at the microscopic level. According to its principles, certain events can occur randomly and cannot be predicted with certainty.

• Epistemological Limitations: Our understanding of causations are only based on our current scientific knowledge. Which are not perfect and are subject to be refined. However as they advance, it is possible to find new discoveries that may challenge our theory towards scientific determinism. 

Psychological Determinism: 

• The belief that all human thoughts, feelings and behaviours are ultimately determined by various factors such as genetics, past experiences and environmental influence. This presents the idea that we may have a causal chain of events that leads to every aspect of our psychological life.

 Sigmund Freud: the theory of the unconscious mind

• The mind is composed of three major components: 

  • The conscious

  • The preconscious 

  • The unconscious

• The unconscious mind particularly plays a large role in shaping human behaviour.

• One example is the unconscious process where an area of mental processes are way beyond the control of the conscious mind, for example, phobias. 

• Freudian slips as Freud proposes are the “slips of the tongue” we get when unconscious desires and contents slip into conscious expression. 

• But these unconscious desires could end up influencing the behaviour as effectively as external forces, like addictions, for example, gambling. 

B. F. Skinner: Theory of behaviourism 

• The theory of behaviourism also known as operant conditioning emphasizes the role of the environment in shaping and controlling behaviour. 

• Behaviour is determined by the consequences that follow it. 

• If behaviour is followed by a positive consequence (reinforcement), it is more likely to be repeated in the future. On the contrary, if the behaviour is followed by a negative consequence (punishment) then it is less likely to be repeated. 

  • Reinforcement 

    • Positive reinforcement involves providing a desirable stimulus.

    • Negative reinforcement removes an undesirable stimulus. 

  • Punishment: the application of an unpleasant stimulus or the removal of a desirable stimulus. 

Hard determinism

• The theory that every human action and choice is the inevitable result of a set of causes, which eliminates the possibility of human freedom. 

• Most determinists are materialistic as their beliefs that human beings are material beings subjected to the laws of the material world. 

Key philosophers: 

• Thomas Hobbes, an English philosopher in the 17th century presented a deterministic view in one of his works “Leviathan”. He believed that human behaviour was determined by natural laws and that freedom is simply the absence of external constraints. Hobbes argued that individuals act according to their desires and aversions which are determined by their nature and the circumstances they encounter. 

• Friedrich Nietzche, a 19th-century philosopher who argued the notion of complete human agency and challenged many factors beyond individual’s control can shape their actions and values. 

Criticisms of hard determinism

1. Incompatibility with human experience: Despite these philosophical arguments, generally have a sense of making choices and decisions to hspa either live within themselves. Hard determinism will contradict this part of human experience. 

2. Lack of moral responsibility: the absence of free will raises the question about the notions of praise, blame, punishment, and personal accountability as this means that humans are not morally accountable for their behaviour. 

3. Scientific challenges: hard determinism faces challenges of scientific disciplines like quantum physics, chaos theory and emergent properties. These concepts are strong evidence towards indeterminism which is the unpredictability of the natural world which could have implications to determinism. 

Soft determinism

• The theory that according to which there are many external factors influencing our decisions but there's an element of freedom still exists. Soft determinists tend to agree that all events are the inevitable results of some sets of causes. However they also point out that some of those causes are internal causes, causes that we have some control over.

Personhood 

• Personhood: The concept of what it means to be a person, including the attributes and characteristics that define personhood.

• Consciousness: The state of being aware and having subjective experiences, often considered a crucial aspect of personhood.

• Identity: The unique set of characteristics, beliefs, and values that distinguish an individual as a person.

• Autonomy: The ability to make independent decisions and act according to one's own will, often seen as a fundamental aspect of personhood.

• Dignity: The inherent worth and value of every individual, regardless of their abilities or circumstances.

• Rights: The entitlements and protections afforded to individuals based on their personhood, often including legal, moral, and ethical considerations.

• Moral agency: The capacity to make moral judgments and be held accountable for one's actions, often associated with personhood.

• Personhood theory: Philosophical frameworks and theories that seek to define and understand the nature of personhood.

Why is personhood important? 

• Personhood normally implies human rights. Once a being is granted personhood, they are given an amount of rights, respect and dignity that protects them from harm. 

• As beloved non-human characters like Superman who is an alien display qualities of a person such as compassion but they’re not necessarily human beings, so will they be granted the same rights as evil characters in the story like Lex Luthor?

• Sufficient conditions: a characteristic that is enough to make something belong to a category, this only works one way. 

  • Example: being a woman is a sufficient condition for a human being.

• Necessary conditions: a characteristic that is absolutely required for something to belong to a certain category. 

  • Example: you have to be male to be a monk but the key difference is that being male isn’t a sufficient condition to be a monk.

Philosophers who focused on personhood:

1. John Locke: Locke argued that personal identity is based on consciousness and memory.

2. Immanuel Kant: Kant emphasized the importance of rationality and autonomy in defining personhood.

3. Jean-Paul Sartre: Sartre explored the concept of existentialism, emphasizing individual freedom and responsibility.

4. Friedrich Nietzsche: Nietzsche questioned traditional notions of morality and explored the idea of the "Ubermensch" or the higher individual.

Consciousness

• One of the characteristics that was most cited as a condition for personhood. The basic characteristics of consciousness are:

  • Wakefulness

  • Awareness

  • Responsiveness

• However, it is difficult to consider this as a necessary condition as factors like people being in the state of a coma or the fact that some people in religions still respect people of the dead, but does that mean they still possess legal rights?

• John Locke focuses on personhood by emphasizing the concept of individual rights and the idea that personal identity is based on consciousness and memory. 

• He argues that individuals have natural rights to life, liberty, and property, and that these rights are inherent to their personhood. 

• Locke also discusses the importance of personal identity, stating that it is based on our ability to remember past experiences and have a continuous consciousness. 

• Locke's focus on personhood centers around the recognition of individual rights and the role of consciousness and memory in defining personal identity.

Self-awareness

Philippe Rochat and the Five Levels of Self-Awareness

• Philippe Rochat's Five Levels of Self-Awareness describe the developmental stages of self-awareness in early childhood.

1. Level 1: Differentiation - Infants start to differentiate themselves from the external world, recognizing their own body as separate from the environment.

2. Level 2: Situation - Toddlers become aware of their actions and their effects on the environment. They start to understand that they can cause changes and have an impact on objects and people around them.

3. Level 3: Identity - Preschoolers develop a sense of self-identity. They recognize themselves as individuals with unique characteristics, preferences, and emotions. They can use personal pronouns like "I" and "me."

4. Level 4: Permanence - Children understand that their physical and psychological characteristics remain stable over time. They recognize that they have a consistent identity that persists even when they are not directly experiencing it.

5. Level 5: Categorical - Older children can categorize themselves based on social and cultural attributes such as gender, age, nationality, and group affiliations. They start to compare themselves to others and develop a more complex understanding of their own identity.

• These levels of self-awareness unfold gradually as children grow and develop, shaping their understanding of themselves and their place in the world.

Immanuel Kant

• Kant's ideas on personhood are centered around the concept of autonomy and rationality. 

• According to Kant, personhood is not based on physical attributes or capabilities, but on the ability to reason and make moral choices. 

• He believed that individuals have inherent dignity and should be treated as ends in themselves, rather than as means to an end. Kant's ideas on personhood emphasize the importance of respecting individual autonomy and moral agency.

Criticisms of Kant's ideas of personhood

1. Exclusion of non-rational beings: Kant's emphasis on rationality as the basis for personhood excludes individuals who lack rational capacities, such as infants, individuals with severe cognitive disabilities, and non-human animals.

2. Lack of consideration for emotions and relationships: Kant's focus on rationality overlooks the importance of emotions and interpersonal relationships in defining personhood and moral worth.

3. Universalizability as a sole criterion: Critics argue that Kant's reliance on universalizability as the sole criterion for moral worth fails to account for the complexities of ethical decision-making and the context-specific nature of moral judgments.

4. Neglect of cultural and individual differences: Kant's universal moral framework may not adequately address the diversity of cultural values and individual circumstances, leading to potential ethical dilemmas and conflicts.

5. Limited recognition of autonomy: Some argue that Kant's emphasis on autonomy as the defining characteristic of personhood neglects the importance of other aspects, such as vulnerability, interdependence, and the influence of social structures.

Morality

• Morality refers to principles or standards of right and wrong behavior that guide individuals and societies. 

• It involves distinguishing between what is considered morally good or bad, and making ethical decisions based on these principles. 

• Morality can be influenced by various factors such as culture, religion, personal beliefs, and societal norms. 

• It plays a crucial role in shaping human behavior and interactions, promoting fairness, justice, and empathy.

• Specific moral values and ethical frameworks can vary across different cultures and individuals.

Turing test

• The Turing Test is a test proposed by Alan Turing in 1950 to determine a machine's ability to exhibit intelligent behavior indistinguishable from that of a human. 

• It involves a human evaluator engaging in a conversation with a machine and a human, without knowing which is which. 

• If the evaluator cannot consistently distinguish the machine from the human, the machine is said to have passed the Turing Test.

The mental distinctions made by Descartes

• Descartes made several mental distinctions, including the distinction between mind and body, known as Cartesian dualism. 

• He distinguished between clear and distinct ideas, which he considered to be true and reliable, and confused or doubtful ideas. 

• Additionally, Descartes made a distinction between innate ideas, which he believed were present in the mind from birth, and adventitious ideas, which are acquired through experience.

Criticisms

• Mind-body problem: questions how the immaterial mind interacts with the physical body.

• Problem of other minds: challenges the ability to know if others have minds similar to our own.

• Neglect of complexity and interconnectedness: criticism of Descartes' dualism for overlooking the complexity and interconnectedness of mental and physical processes.

• Neglect of emotions and unconscious mental states: argument that Descartes' emphasis on rationality overlooks the role of emotions and unconscious mental states.

• Limitations and philosophical challenges: overall criticisms that highlight the limitations and philosophical challenges associated with Descartes' mental distinctions.

Freedom (Existentialism)  

Existentialism

• A philosophical movement that emerged in the 20th century focusing on the individual’s subjective experience and existence, emphasizing the freedom, responsibility and meaning of human life. 

• Existentialism rejects the idea that there is any predetermined or essential meaning to human life, instead, it asserts that individuals must create their own earnings and values through their choices and actions. 

Nihilism

• Derived from the Latin word “nihil” which means nothing, nihilism rejects the existence of any inherent or universal meaning in the world and denies the existence of objective moral or value systems. 

• Most notably associated with the writings of Friedrich Nietzsche, in which he argued that traditional moral and religious frameworks had lost their credibility, leaving a void in the understanding of existence. This void can either lead to the creation of new values but also to a state of meaninglessness  

Active Nihilism 

• The proactive engagement with the recognition of the absence of objective meaning involves an intended rejection of traditional beliefs and values as there is also the desire to create new values or systems of meaning. 

• This encourages individuals to take responsibility for constructing their values due to the recognition of the lack of inherent meaning. 

Passive Nihilism 

• The more resigned, apathetic response to the absence of meaning, involves a sense of disengagement or acceptance of the meaninglessness of existence without actively seeking alternatives. 

• Sometimes believers would engage in pleasure-seeking or immediate gratification without concern for long-term consequences. 

Similarities and differences in Existentialism and Nihilism 

• Similarities: 

1. Both reject the notion of objective, predetermined meaning or purpose in life. Challenging the idea that there is a universal, inherent meaning to human existence. 

2. Emphasizes the importance of individual freedom and personal responsibility. They recognise the significance of individual agency in shaping one’s life and values. 

3. Both acknowledge the existential angst or anxiety that arises from the recognition of the absence of objective meaning, exploring the dilemmas faced in confronting the potential meaninglessness of existence. 

• Differences: 

1. The attitude towards meaning and value, existentialism seeks to find subjective meaning in the face of the absence of objective meaning, emphasizing the capacity to shape their own life and values through authentic choices. While nihilism generally asserts that life is meaningless, denying the existence of any objective meaning. 

2. Existentialism promotes the idea of personal authenticity and the pursuit of values that align with one’s true self by addressing moral and ethical questions. Nihilism can lead to moral skepticism or relativism as it denies the existence of objective moral values and questions the validity of ethical systems. 

3. Existentialism generally has a more positive outlook on life due to the emphasis on the possibilities of personal growth. In contrast, nihilism can be seen as more pessimistic. 

Modernism

• A broad cultural and intellectual movement that emerged as a response to the social, political, technological and artistic changes of the time, encompassing fields including literature, visual arts, architecture, music and philosophy. 

• Some key features are innovation, rejection of realism, the influence of science and technology and its global reach. 

Relativism

• A philosophical position that asserts that truth, knowledge, morality or values are not absolute or universal but instead are relative to individuals, cultures, historical contexts or subjective perspectives. 

• The forms of relativism include: 

• Epistemological Relativism: holds that knowledge or truth is relative to individuals or social groups. Asserts that there is no objective or universally valid knowledge but that knowledge is shaped by subjective experiences 

• Moral relativism: Argues that moral judgment or ethical principles are relative to individuals, cultures or societies. 

• Cultural relativism: Cultural relativism maintains that cultural practices, customs, or values should be understood within their cultural context and not judged by external standards. 

Nietzsche

• Nietzsche significantly influenced both of these ideas, although he never explicitly referred to them in his theories, his ideas contributed to the development of these philosophical movements. 

1. Relativism: Nietzsche criticized traditional metaphysics, morality and religious beliefs, arguing that they were based on subjective human interpretations rather than inherent truths.  Nietzche’s perspectivism suggests that individual perspectives, historical contexts and cultural influences shape knowledge and truth. Aligning with the ideas of epistemological and moral relativism. 

2. Modernism: Nietzsche’s rejection of tradition and his call for the creation of new values beyond establishing norms resonates with the spirit of experimentation, and innovation which characterized the modernist movement. His concept of “will power” and his critique of traditional morality and religious beliefs addressed the prevailing social and cultural institutions at the time, aligning with the modernist impulse to question and transform established systems. 

• The story of the madman is a famous passage from Nietzsche’s book “The Gay Science” the story follows: 

  • A madman enters a marketplace claiming that he is searching for god. 

  • The people in the marketplace were described as atheists, mocked and ridiculed the madman and told him that God was dead and they had killed him. Bewildering the madman with this information. 

  • The madman then goes into a monologue, expressing the consequences of the death of God, that humanity will lose its source of meaning, value and moral order. And will result in a widespread nihilism, despair and moral chaos.  

  • This story of the madman illustrates Nietzsche’s thesis by showing how the death of God challenges traditional beliefs and moral systems, leaving individuals to grapple with the search for meaning in a world that lacks objective guidance. 

The self 

Is there such a thing as the self?

• The self, in a philosophical standpoint

• The self questions consciousness, personal identity and the nature of the mind. 

• It has been debated whether the self is a unified and enduring entity or a series of ever-changing perceptions and experiences.

The Buddhist notion of anattā or “not-self” + in contrast to western ideations

• Annata (translated to the “not self”) is a central basis in Buddhist philosophy. Buddhism provides an alternative viewpoint to positing an intrinsic self: 

  • Impermanence of self 

    • Self in Buddhism is sectioned into five skandhas: 

      • Form (physics body)

      • Feelings

      • Perceptions (intuition)

      • Mental formations (habits)

      • Consciousness. 

    • Each of these Skandhas is in a continuous flux, when evolved the percept of self will evolve → eventually denying the existence of eternal identity.

  • Absence of permanent identity

    • Before evolved, the perception of the self is an illusion formed by a temporary combination between the skandhas. This concept isn’t supposed to let people down but rather acknowledge that there is a path to liberty in suffering and motivates individuals to let go of self-centered desires. 

• This notion of anatta exudes parallels with Western ideations, for example an Existentialist perspective where (in summary):

  • Existentialist philosophers like Jean Paul Satre would propose that the concept of the “self” is a developing scheme. Where it will be refined through the choices and experiences of one throughout their lives and the “self” is not inherent. 

  • The freedom to decide for yourself brings responsibility, the anxiety that individuals may feel could be a consequence of the overwhelming liberty of existence. 

  • Although both viewpoints were derived from different cultural and religious perspectives: 

    • They both managed to reach the common ground that the “self” is constantly evolving, through self-reflection and realizing what choices are best for the individual. 

    • However, existentialism strongly emphasizes an individual taking accountability for their actions which is less touched upon in Buddhism. 

Simone De Beauvoir’s rejection of the concept of a solipsistic isolated self

• Simone de Beauvoir (1908-1986) was a feminist philosopher, who mainly focused on existentialism during post-war France. One of her theories “The second sex: Woman as Other” is a seminal work on feminist philosophy published in 1949.

• This theory rejects the concept of a solipsistic isolated self as it emphasizes the social construction of identity, the relational aspect of identity formation and the impact of social norms. 

• Beauvoir stressed recognising the significance of the patriarchal structures on women’s lives, highlighting that identity is shaped through relationships, interactions and engagement with the wider world.

Pros of Simone de Beauvoir's theory "The Second Sex"

1. Integrates existentialist philosophy, emphasizing individual freedom and the importance of personal choice in shaping one's identity.

2. The theory acknowledges the intersectionality of gender with other social categories, such as race and class, highlighting the unique experiences and challenges faced by different groups of women.

3. Beauvoir's analysis uncovers the patriarchal systems that eternalise women's subordination, promoting critical examination of power dynamics and social inequalities.

4. It has been an influential guide to feminist movements worldwide, contributing to the advancement of women's rights and gender equality.

Cons of Simone de Beauvoir's theory "The Second Sex"

1. While Beauvoir recognises the intersectionality of gender, her theory has been criticized for not fully including the experiences of women from diverse racial, ethnic, and cultural backgrounds.

2. Beauvoir focuses majorly on the experiences of middle-class women, potentially neglecting the obstacles faced by women from lower socioeconomic backgrounds.

3. Overemphasis on Biology: Critics contend that Beauvoir's theory places excessive emphasis on biological differences between men and women, potentially reinforcing gender essentialism.

4. Lack of Practical Solutions: While Beauvoir's theory provides a critical analysis of gender inequality, it has been criticized for not offering concrete solutions or strategies for achieving gender equality in society.

The relational self (e.g. Confucius)

• Confucius is a fifth century Chinese thinker, looking into the concept of relational self.

• According to his thought, individual beings are seen as an interconnected being whose identities are morphed through the relationship created with other individuals. 

• Also known as “ren or “jen”, the theory of relational self presents the significance of creating harmonious relationships within society. These relationships are made to develop virtuous qualities and strive to engage with ethical behaviour. 

• The relational self is not only based on an individual's fulfillment, but also the wellbeing and the flourishing of others. 

Pros of Confucius's theory on the relational self:

1. Confucius's theory highlights the importance of maintaining harmonious relationships with others. This promotes a sense of unity and cooperation within society, leading to a more peaceful and stable community.

2. Confucius acknowledged that individuals should aim for self-improvement via moral cultivation. This focus on personal ethics encourages individuals to grow virtues such as benevolence and filial piety, which can contribute to a more virtuous society.

3. Confucius stressed the value of family and the role it plays in shaping an individual's nature. This focus on filial piety and respect for elders encourages strong family bonds and a sense of duty towards one's relatives, which can contribute to a more supportive society.

4. Confucius believed in the transformative power of education. His theory advances the idea that education is essential for personal growth and societal advancement. By prioritizing education, individuals can attain knowledge, formulate critical thinking skills, and contribute to the improvement of society.

Cons of Confucius's theory on the relational self:

1. Potential for conformity: Confucius's theory places a strong emphasis on social norms and expectations. This can lead to a stifling of individuality and creativity, as individuals may feel pressured to conform to societal standards rather than express their unique perspectives and ideas.

2. Limited focus on individual rights: Confucius's theory prioritizes the collective over the individual. This may neglect the importance of individual rights and freedoms, potentially leading to the suppression of personal autonomy and self-expression.

3. Gender inequality: Confucius's theory reinforces traditional gender roles, placing men in positions of authority and women in subordinate roles. This perpetuates gender inequality and limits opportunities for women to fully participate in society on an equal footing with men.

4. Potential for hierarchical relationships: Confucius's theory promotes hierarchical relationships based on age, social status, and authority. While this can contribute to social order, it may also perpetuate power imbalances and limit social mobility, as individuals are expected to adhere to their assigned roles within the hierarchy.

Unit 2: Aesthetics: The Philosophical Study of Beauty and Taste

Unit 1: Aesthetics

• Aesthetics - defined as the philosophy of beauty and taste.

• It is closely tied to the philosophy of art.

• Defining aesthetics is challenging, self-definition is a major task.

• Explores beauty, ugliness, the sublime, elegance, taste, criticism, fine art, contemplation, sensuous enjoyment, and charm.

• “What should a philosopher study in order to understand such ideas as beauty and taste?”

Unit 2: What is The Concept of Taste in Aesthetics?

• The notion of the aesthetic originates from the notion of taste. The significant philosophical interest in taste during the 18th century is intricate, yet one aspect stands out: the theory of taste from that era arose partly as a response to the increasing prominence of rationalism, particularly concerning beauty, and the growing emphasis on egoism, particularly concerning virtue.

2.1: Immediacy

• Rationalism regarding beauty - posits that judgments of beauty stem from reason; in other words, we assess things as beautiful through a process of reasoning, often involving deduction from principles or application of concepts.

2.2: Disinterest

• Egoism - concerning virtue, it suggests that deeming an action or quality virtuous entails finding pleasure in it due to the belief that it serves one's interests. 

• Hobbesian perspective - A prominent example prevalent in the early 18th century, asserting that considering an action or quality virtuous stems from finding pleasure in it due to the belief that it enhances personal safety.

Unit 3: The Five Aesthetic Concepts

3.1: Concept One: The Aesthetic Objects

• Artistic formalism - posits that the properties of an artwork that are artistically significant—those that determine its status as an artwork and its quality—are solely formal. 

• Formal properties - typically understood as properties perceivable through sight or hearing alone, are considered the primary factors in determining the artistic merit of an artwork.

• Derived from the immediacy and disinterest theses, which suggest that representational properties and those with practical import are artistically irrelevant.

• Prominent formalist advocates were professional critics like Eduard Hanslick, Clive Bell, and Clement Greenberg, who championed formal properties in music and painting.

• Monroe Beardsley and Nick Zangwill also defended formalism, but the rise of conceptual art challenged its validity, particularly highlighted by Arthur Danto's critique.

• Danto argued that form alone doesn't determine artwork status or value, using Warhol's Brillo Boxes as an example.

• Kendall Walton critiqued formalism, asserting that aesthetic properties depend on the perceived category of the artwork, challenging the notion of solely formal properties.

• Allen Carlson extended Walton's argument to the aesthetics of nature, suggesting that aesthetic judgments about natural items also depend on their perceived categories, undermining the idea of formalism in nature.

3.2: Concept Two: The Aesthetic Judgment

• The eighteenth-century debate between rationalists and theorists of taste centered on the immediacy thesis, questioning whether beauty judgments rely on applying principles.

• Despite disagreement on the existence of beauty principles, both Hutcheson and Hume acknowledged their presence, suggesting they could be uncovered through empirical means.

• The contemporary debate between particularists and generalists in aesthetics echoes the historical rationalist versus sentimentalist debate but lacks clarity due to differing interpretations of aesthetic judgment.

• Particularists - like Arnold Isenberg and Frank Sibley argue against the existence of principles governing aesthetic judgment, emphasizing the role of perceptual experience in guiding aesthetic evaluation.

• Generalists - such as Monroe Beardsley and George Dickie assert the existence of general aesthetic principles, highlighting inherently positive properties like grace or dramatic intensity.

• Sibley's particularism and generalism address different aspects of aesthetic judgment, focusing on the role of descriptive features and inherent positive properties, respectively.

• The immediacy thesis, asserting that aesthetic judgments are non-inferential, is widely accepted but has faced challenges from critics like Davies and Bender, who propose alternative principles for justifying aesthetic verdicts.

• Davies suggests relativizing critical principles to artistic type, while Bender proposes inductive reasoning based on tendencies rather than absolute principles.

• Despite attempts to justify aesthetic judgments through principles, the non-inferential nature of aesthetic judgment remains a central tenet of the immediacy thesis.

3.3: Concept Three: The Aesthetic Attitude

• The Kantian notion of disinterest in aesthetic judgment transitioned to aesthetic-attitude theories in the early to mid-20th century.

• Kant described aesthetic judgment as contemplative rather than practical, leading to the idea that the aesthetic attitude is disinterested, unconcerned with practical aims.

• Schopenhauer's aesthetic theory shifted focus from disinterested pleasure to disinterested attention, suggesting that aesthetic value lies in will-less contemplation, providing a respite from desire-induced pain.

• Edward Bullough and Jerome Stolnitz developed influential aesthetic-attitude theories, emphasizing disinterested and sympathetic attention to objects for aesthetic appreciation.

• Stolnitz defines the aesthetic attitude as attending to an object with no purpose beyond attending, resulting in a richer experience of its features.

• Bullough, preferring the term "psychical distance", suggests achieving aesthetic appreciation by detaching oneself from personal needs and interpreting subjective affections as characteristics of the phenomenon.

• Critics like George Dickie challenged the notion of the aesthetic attitude, arguing that purported examples of interested attention are cases of inattention.

• Dickie contends that a difference in purpose does not imply a difference in attention, suggesting that the concept of disinterest may not be essential for aesthetic appreciation.

• While the notions of disinterest and psychical distance may not fully define the aesthetic attitude, they remain useful in explaining certain aesthetic experiences, such as the Athenian reaction to Phrynicus's tragedy "The Fall of Miletus."

3.4: Concept Four: The Aesthetic Experience

• Theories of aesthetic experience can be categorized into internalist and externalist theories, depending on whether they appeal to features internal or external to the experience.

• Internalist theories - predominant in the early to mid-20th century, focus on phenomenological features of experience, such as focus, intensity, coherence, and completeness.

• John Dewey and Monroe Beardsley are notable proponents of internalist theories, emphasizing the introspective discovery of common features in aesthetic experiences.

• Beardsley's internalist theory, outlined in "Aesthetics" (1958), identifies focus, intensity, coherence, and completeness as key features of aesthetic experience.

• George Dickie criticizes Beardsley's internalism, arguing that Beardsley fails to distinguish between the features experienced in aesthetic objects and the features of aesthetic experiences themselves.

• Dickie challenges Beardsley's characterization of coherence and completeness in aesthetic experience, suggesting that these qualities belong to the objects rather than the experiences.

• The debate between Beardsley and Dickie shapes the development of theories of aesthetic experience, leading to a shift from internalism to externalism.

• Externalist theories - like Beardsley's later work in "The Aesthetic Point of View" (1970), define aesthetic experience as an experience with aesthetic content, focusing on the object's aesthetic features rather than internal experiential qualities.

• While the shift from internalism to externalism relinquishes the tie between aesthetic meaning and internal experiential features, it retains the ambition of grounding aesthetic value in the value of aesthetic experience.

3.5: Concept Five: The Aesthetic Value

3.5.1: The Aesthetic Question: What makes aesthetic value aesthetic? 

• This question is sometimes referred to as the demarcation question. 

• The prevailing answer to this question is aesthetic formalism, which asserts that aesthetic value derives from objects' perceptual properties. 

• This view rose to prominence alongside artistic formalism during the late 19th and early 20th centuries. 

• Aesthetic formalism posits that aesthetic value is perceptual and can be attributed strictly to an object's perceptual properties. However, it struggles to account for the aesthetic value attributed to non-perceptual properties, such as those found in literature. 

• Alternative approaches propose that aesthetic value is perceptual because we perceive objects as having it, rather than deriving it strictly from perceptual properties.

3.5.2: The Normative Question: What makes aesthetic value?

• This question is sometimes referred to as the normative question. 

• The prevailing answer to this question is aesthetic hedonism, which suggests that aesthetic value is valuable because it provides pleasure when experienced. 

• This view gained prominence in the 19th century, notably through the work of Schopenhauer. 

• Aesthetic hedonism - asserts that the value of aesthetic objects lies in the pleasure they afford when experienced. However, objections to hedonism have arisen, challenging its ability to explain certain aspects of aesthetic experience, such as instances where pleasure is not the primary response.

Unit 3: Epistemology

How Do We Experience the World Around Us?

Rationalism and Empiricism

These two foundational theories offer different explanations for how we acquire knowledge:

• Rationalism: Knowledge is primarily acquired through reason and intellectual intuition. 

  • Key rationalists like René Descartes, Baruch Spinoza, and Gottfried Wilhelm Leibniz argue that certain knowledge, such as mathematical truths, is innate and can be accessed through deductive reasoning.

• Empiricism: Knowledge is primarily acquired through sensory experience. 

  • Prominent empiricists like John Locke, George Berkeley, and David Hume argue that the mind starts as a blank slate and that all knowledge is derived from experience through induction and observation.

Kinds of Knowledge

Epistemology

• Definition and Origin

  • Epistemology: The study or science of knowledge.

  • Greek Roots: "Episteme" (knowledge) and "logos" (study or science).

  • Relation to “-ology”: The root "logos" is also the basis for terms like psychology, anthropology, and logic.

Uses of the Term “Knowledge”

• Psychological Conviction: Knowing in the sense of strong belief (e.g., "I just knew it wouldn’t rain, but then it did").

• Philosophical (Factive) Sense: Knowing something that is true. Philosophers argue that one cannot know something that is not the case.

Types of Knowledge

• Procedural Knowledge (Know-how)

  • Examples: Knowing how to ride a bicycle, knowing how to drive from one city to another.

• Acquaintance Knowledge (Familiarity)

  • Examples: Knowing a person (e.g., the department chairperson), knowing a place (e.g., Philadelphia).

• Propositional Knowledge (Knowledge-that)

  • Definition: Knowledge expressed by declarative sentences that describe facts or states of affairs.

  • Examples: "Dogs are mammals," "2+2=4," "It is wrong to murder innocent people for fun."

  • Characteristics: Propositions can be true or false.

Focus of Epistemologists

• Propositional Knowledge: The primary focus in epistemology, dealing with statements of fact.

• Declarative Sentences: Statements that describe facts or states of affairs.

Scope of Propositional Knowledge

• Wide Range of Matters: Includes scientific, geographical, mathematical knowledge, self-knowledge, and any other field.

• Knowable vs. Unknowable Truths: Epistemology seeks to establish what can or cannot be known.

Meta-Epistemology

• Study of Criteria for Knowledge: Understanding the fundamental nature of knowledge itself.

Sources of Propositional Knowledge

• A Priori Knowledge

  • Definition: Knowledge independent of experience, known through reason alone.

  • Examples: Logical truths (e.g., law of non-contradiction), abstract claims (e.g., ethical claims).

• A Posteriori Knowledge

  • Definition: Knowledge dependent on sensory experience.

  • Examples: Knowing the color or shape of an object, geographical knowledge.

Philosophical Stances

• Rationalism: Belief that all knowledge is ultimately grounded in reason.

• Empiricism: Belief that all knowledge is ultimately grounded in experience.

Collective Knowledge

• Social Epistemology: The study of how groups, institutions, or collective bodies acquire knowledge.

The Nature of Propositional Knowledge

• Focus: Narrowed to propositional knowledge, which involves statements of fact.

• Central Questions:

  • What constitutes knowledge?

  • What does it mean for someone to know something?

  • What distinguishes someone who knows something from someone who does not?

Characterizing Knowledge

• General Characterization Needed: A broad definition applicable to any kind of proposition.

• Analysis of the Concept of Knowledge:

  • Epistemologists aim to identify a correct and complete analysis of knowledge.

  • This involves identifying necessary and sufficient conditions.

Necessary and Sufficient Conditions

• Necessary Conditions: Conditions that must be met for a proposition to qualify as knowledge.

• Sufficient Conditions: Conditions that, if met, ensure that a proposition qualifies as knowledge.

Traditional Analysis of Knowledge

• The standard definition in epistemology traditionally includes the following conditions:

• Justified True Belief: The tripartite definition, where knowledge is seen as a belief that is true and justified.

  • Belief: The person must believe the proposition.

  • Truth: The proposition must be true.

  • Justification: The person must have adequate justification for believing the proposition.

Challenges and Refinements

• Gettier Problems: Cases presented by Edmund Gettier showing that justified true belief may not be sufficient for knowledge, leading to further refinements and additional conditions.

Beliefs

Belief as a Component of Knowledge

Knowledge as a Mental State

• Knowledge is Mental: Knowledge exists in the mind and cannot be attributed to unthinking things.

• Specific Kind of Mental State: Knowledge is distinct from other mental states like desires and intentions.

Relationship Between Belief and Knowledge

• Knowledge as a Kind of Belief: To have knowledge about something, one must have beliefs about it.

• Example: If someone does not believe they will receive a raise, they cannot know they will receive one.

Occurrent vs. Non-Occurrent Beliefs

• Occurrent Beliefs: Beliefs that an individual is actively thinking about at a given moment.

• Non-Occurrent (Background) Beliefs: Beliefs that are held in the background and not actively considered at a specific time.

• Knowledge Types: Most knowledge is non-occurrent (background knowledge), while a smaller portion is occurrent.

Truth

Truth as a Condition of Knowledge

Belief and Knowledge

• Belief is Necessary but Not Sufficient: To know something, one must believe it, but belief alone does not constitute knowledge.

• True vs. False Beliefs: We aim to increase our true beliefs and minimize false ones to acquire knowledge.

Purpose of Beliefs

• Descriptive Aim: The typical purpose of forming beliefs is to describe or capture the way things actually are, seeking a match between mind and world.

• Other Purposes: Beliefs may also be formed for reasons such as self-deception or creating positive attitudes, but these do not aim at knowledge.

Objective Truth

• Assumption of Objective Truth: The concept assumes that there is an objective reality that beliefs can match or fail to match.

• Factive Knowledge: Knowledge in the factive sense requires that there be facts to know. Without facts, there can be no knowledge.

Truth as a Condition of Knowledge

• Truth Requirement: For a belief to constitute knowledge, it must be true.

• Relativism Challenge: Some relativists deny objective truth, which would imply that knowledge, as traditionally understood, cannot exist.

• Domain-Specific Truth: In domains without objective truths (e.g., subjective beauty), beliefs cannot constitute knowledge.
  
  

Justification

Justification as a Component of Knowledge

Necessity of Justification

• True Belief is Not Sufficient: Knowledge requires not just a true belief but a true belief formed in the right way.

• Right Way: Beliefs must be formed through sound reasoning and solid evidence, not through luck or misinformation.

Definition of Justification

• Justified Belief: A belief is justified if it is based on evidence and reasoning.

• Contrast with Unjustified Belief: Unjustified beliefs may be true but are formed through luck, misinformation, or faulty reasoning.

Fallibilism

• Human Fallibility: The view that humans can have knowledge even if their beliefs might have turned out to be false.

• Spectrum of Beliefs: Beliefs lie on a spectrum from necessarily true to true by luck, with justified beliefs falling somewhere in between.

Example of Justification

• Example: If a weatherman predicts a 90% chance of rain and you believe it will rain based on this prediction, your belief is justified even if there was a chance it could have been false.

• Defeasible Reasoning: Justified beliefs are based on evidence and reasoning that make them likely to be true, even if not absolutely certain.

Independence of Truth and Justification

• Independent Conditions:

  • Unjustified True Beliefs: Beliefs can be true but unjustified.

  • Justified False Beliefs: Beliefs can be justified but false.

• Correlation: Justified beliefs are more likely to be true than unjustified ones, but justification alone does not guarantee truth.

The Gettier Problem

Background

• Justified True Belief (JTB): For a long time, knowledge was thought to be accurately described by the JTB account, which holds that knowledge is a justified true belief.

• Gettier's Challenge: In 1963, Edmund Gettier published an article presenting cases where justified true belief does not seem to equate to knowledge.

Gettier Cases

• Structure of Examples: Gettier provided examples where an individual has a belief that is true and justified, yet does not constitute knowledge due to the role of luck.

• Example of a Stopped Clock:

  • Scenario: A reliable clock stops at 11:56 PM. Twelve hours later, someone glances at it and forms the belief that it is 11:56 AM.

  • True Belief: The belief is true since it coincidentally matches the correct time.

  • Justified Belief: The person has no reason to doubt the clock and is justified in relying on it.

  • Lack of Knowledge: Despite the true and justified belief, the person does not actually know the time due to the role of luck. If they had looked at the clock a bit earlier or later, their belief would have been false.

Implications of Gettier Cases

• Challenge to JTB: These examples demonstrate that justified true belief can fail to constitute knowledge because of the element of luck.

• Luck and Justification: The justification condition was meant to ensure knowledge is based on solid evidence, but Gettier cases show that even justified true beliefs can involve luck.

• Need for Refinement: To address the Gettier Problem, epistemologists must:

  • Re-examine JTB: Determine whether all instances of justified true belief truly constitute knowledge.

  • Refine the Analysis: Propose additional conditions or modifications to the JTB account to exclude cases where luck plays a role.

The No-False-Belief Condition

Initial Proposal

• Simple Solution: One might think the Gettier Problem can be solved by adding a condition that no false beliefs are involved in the justification process.

• Revised Analysis: To constitute knowledge, a belief must be:

  • True

  • Justified

  • Formed without relying on any false beliefs

Example and Limitation

• Original Example: Belief that the clock is working properly (a false belief) justifies the true belief about the time.

• Modification of Example: Even if no false beliefs are involved, issues remain:

  • True General Belief: Suppose I believe generally that the clock usually works properly (which is true).

  • Justification: This general belief justifies my specific belief that the time is 11:56.

  • Lack of Knowledge: Despite no false beliefs, it still seems I do not know the time because my belief is still based on luck.

Implications

• Insufficiency of No-False-Belief Condition: Even when all beliefs involved are true, justified true belief can still fail to constitute knowledge if luck plays a role.

• Persistent Role of Luck: The role of luck in the belief formation process undermines the sufficiency of the no-false-belief condition for defining knowledge.

The No-Defeaters Condition

Concept of Defeaters

• A defeater is a proposition that, if known or believed, would undermine or invalidate the justification for a belief.

• Types of Defeaters:

  • Explicit Defeater: A belief or knowledge of a false proposition that would directly contradict the justification.

  • Implicit Defeater: A proposition that is implicitly assumed in the reasoning process and, if false, undermines the justification.

Example of a Defeater

• Clock Example:

  • False Belief: The belief that the clock is currently working properly is false.

  • Implicit in Reasoning: Even if not explicitly formed, the belief that the clock is working properly is implicit in my reasoning when I look at the clock and believe it is 11:56.

  • Impact of Realization: If I realized the clock wasn’t working, I wouldn’t trust the clock to tell the correct time, and thus my belief about the time would not be justified.

No-Defeaters Condition

• Condition Explained: To constitute knowledge, a belief must:

  • Be true.

  • Be justified.

  • Have no defeaters—there must not be any false propositions, that if known or believed, would undermine the justification for the belief.

Addressing the Gettier Problem

• Solving the Issue: By adding the no-defeaters condition, we ensure that the justification for a belief is robust and not based on any false premises or assumptions that could invalidate it.

• Importance of Truth in Justification: This condition acknowledges that for justification to lead to knowledge, it must not be undermined by any unknown false beliefs.

Acceptance by Epistemologists

• Support for the Condition: Many epistemologists find this analysis to be correct and sufficient to address cases like those presented by Gettier.

• Refinement of Knowledge Definition: The addition of the no-defeaters condition refines the traditional JTB (justified true belief) account to handle cases involving luck and false assumptions.

Casual Accounts of Knowledge

• Causal accounts of knowledge emerge as an alternative to the traditional Justified True Belief (JTB) account in response to the Gettier problem, which reveals that the JTB criteria can be met without constituting true knowledge due to the involvement of luck. 

• Gettier-type examples demonstrate situations where a belief is justified and true but the connection between the truth and justification involves an element of luck.

Connection Between Truth and Justification:

• Traditional JTB requires a belief to be justified and true, but Gettier examples show that this is not sufficient for knowledge because the justification and truth can be coincidentally aligned due to luck.

• In true knowledge cases, the same factors should be responsible for both the justification and the truth of the belief. For instance, a working clock justifies the belief about the time and simultaneously ensures its truth.

Role of Causality:

• Causal accounts propose that for a belief to be considered knowledge, there must be a direct causal link between the fact that makes the belief true and the person’s belief in that proposition.

• This approach preserves the truth condition, as the proposition must reflect a fact for a causal relationship to exist.

Incompatibility with Fallibilism:

• Fallibilism is the notion that a belief can be justified yet false.

  • Causal accounts, however, imply that if there is a causal connection, the belief cannot be false, thus opposing the idea of fallibilism.

• Causal accounts do not inherently address justification.

  • However, one might attempt to reformulate fallibilism in new terms to reconcile it with causal accounts, though this would require significant modification.

Implications of Causal Accounts:

• Gettier Problems:

  • Causal accounts aim to eliminate the luck element seen in Gettier cases by ensuring a direct causal link between the fact and the belief, thus resolving the misalignment between truth and justification.

• Knowledge Definition:

  • Shifts from needing a separate justification condition to focusing on the causal relationship, simplifying the criteria for knowledge but also complicating its practical assessment.

Example:

• Consider the scenario where you look at a properly functioning clock to determine the time:

• JTB View: You believe the time is 11:56 because the clock says so (justified), and it is indeed 11:56 (true).

• Gettier Example: If the clock stopped exactly 24 hours ago at 11:56, your belief is justified (based on the clock) and true (by coincidence) but not knowledge due to the luck element.

• Causal Account: Your belief that the time is 11:56 is knowledge only if there is a direct causal link between the actual time (fact) and your belief (looking at the working clock), eliminating the coincidental nature.
  
  

Nature of Justification

• The concept of justification is central to the Gettier problem and the analysis of knowledge, yet it remains elusive.

• To better understand justification, we need to consider how it contributes to the goal of forming true beliefs while avoiding error.

• This goal implies that justified beliefs are those formed in a way that optimally pursues truth.

• When we evaluate whether a belief is justified, we essentially assess whether the belief matches the world and whether this match was achieved correctly.

Two Approaches to Justification:

Internalist Approach (Believer's Mind):

• This perspective focuses on the mental states and processes of the believer.

• Justification is about the cognitive processes, evidence, and reasons available to the believer.

• The belief is justified if it is supported by adequate reasons or evidence from the believer's perspective.

• Emphasizes access to and awareness of justifying factors, suggesting that a belief is justified if the believer can internally verify its truth.

Externalist Approach (The World):

• This perspective emphasizes the relationship between the belief and the external world.

• Justification depends on factors outside the believer’s mental states, such as the reliability of the belief-forming process.

• A belief is justified if it is produced by a process that reliably leads to truth, regardless of the believer's awareness of this reliability.

• Focuses on the objective connection between the belief and the actual state of affairs in the world.

Implications and Challenges:

Internalism:

• Provides a clear criterion for the believer to assess justification.

• Faces challenges in explaining how internal access to reasons or evidence guarantees truth.

• May struggle with the problem of infinite regress, where justifying beliefs require further justifications.

Externalism:

• Avoids the regress problem by grounding justification in reliable processes.

• Can account for justified beliefs even when the believer is unaware of the reliability.

• May be criticized for disconnecting justification from the believer's perspective and subjective experience.

The Gettier Problem and Justification:

• Gettier cases illustrate situations where a belief is true and justified yet fails to constitute knowledge due to luck.

• These cases highlight a gap in the traditional understanding of justification.

• By exploring internalist and externalist approaches, we aim to refine our understanding of justification to address this gap.

Internalism

• Core Idea: Justification of a belief is determined solely by factors internal to the believer’s mind.

• Mental States: Beliefs, sensory inputs (sense data), and beliefs about the relations between various beliefs.

Belief Formation:

• Mental Process: Beliefs are formed through mental processes involving other mental states.

• Justification Criteria: For a belief to be justified, it must be supported by other justified mental states.

Basing or Support Relation:

• Entailment vs. Probability:

  • Entailment: If belief A is based on belief B, the truth of B must entail the truth of A.

  • Probabilistic Support: To allow for fallibility, B must provide good reasons to believe that A is true, making it likely or probable.

Good Reason for Belief:

• Essential Part of Internalism: A good reason is necessary to establish the justification of a belief.

• Justified Supporting Beliefs: Belief B must itself be justified to confer justification on belief A.

Regress Problem:

• Issue of Infinite Justification:

  • Chain of Justification: If belief B must be justified by another belief C, and C by D, this leads to a potential infinite regress.

• Four Possibilities:

  • Infinite Regress: The series of justified beliefs continues infinitely.

  • Circular Justification: The series of justified beliefs circles back to its beginning (e.g., A is based on B, B on C, C on D, and D on A).

  • Unjustified Starting Point: The series of justified beliefs begins with an unjustified belief.

  • Foundational Belief: The series begins with a belief that is justified, but not by virtue of being based on another justified belief.

Implications for Internalism:

• Deciding Among Alternatives: An internalist account must choose among these possibilities to provide a coherent theory of justification.
  
  

Foundationalism

Regress Argument Analysis:

• Rejecting Alternatives:

  • Infinite Regress: Unacceptable because the human mind has a finite number of beliefs, and belief formation must start somewhere.

  • Circular Justification: Fallacious because it involves reasoning in a circle.

  • Unjustified Starting Point: Invalid because it makes all subsequent beliefs unjustified.

Conclusion:

• Alternative 4 is correct by elimination: Some beliefs (basic beliefs) must be justified independently of other beliefs.

Types of Justified Beliefs:

• Basic Beliefs:

  • Definition: Beliefs that initiate a chain of justification and do not derive their justification from other beliefs.

  • Role: Confer justification on other, non-basic beliefs.

  • Justification Source: Must be justified in a way other than by relations to other beliefs (self-justified or from a non-doxastic source).

• Non-Basic Beliefs:

  • Definition: Beliefs that derive their justification from other beliefs.

  • Role: Dependent on basic beliefs for their justification.

Asymmetrical Relationship:

• Structure of Justification:

  • Asymmetry: If belief A is based on belief B, B cannot be based on A.

  • Foundational Structure: Basic beliefs serve as the foundation for non-basic beliefs, creating a non-circular and non-infinite structure of justified beliefs.

Source of Justification for Basic Beliefs:

• Self-Justified Beliefs: Beliefs that justify themselves inherently without reliance on other beliefs.

• Non-Doxastic Sources: Sensory inputs or other external factors that provide justification without being beliefs themselves.
  
  

Coherentism

Critique of Foundationalism:

• Dissatisfaction with Foundationalism: Internalists might reject the idea that some beliefs can be justified without being based on other beliefs.

• Flaw in the Regress Problem: The problem assumes that justification is linear, with beliefs supporting other beliefs in a hierarchical, asymmetrical manner.

Coherentist Approach:

• Holistic Justification:

  • Mutual Support: Beliefs derive their justification from being part of a coherent set of beliefs that support each other.

  • Non-Linear: Justification is not a linear chain but a network where each belief is justified by its relationship with the entire system of beliefs.

• Coherence Criteria:

  • Beyond Consistency: Coherence must involve more than logical consistency; there must be a positive support relationship among beliefs.

  • Explanatory Relationship: The beliefs in a coherent set should support each other in a way that they explain or reinforce one another.

Isolation Objection:

• Potential Problem:

  • Isolated Coherence: A set of beliefs can be coherent yet disconnected from reality.

  • For example, a fictional narrative can be internally coherent but not justified as knowledge about the real world.

Implications for Internalism:

• Reality Connection: Justification requires not just internal coherence but also a match between beliefs and the actual world.

• Challenge for Coherentism: To address the isolation objection, coherentists must find a way to ensure that a coherent set of beliefs is also connected to reality.

Externalism

• Externalism: Justification depends on factors external to the believer’s mind. This approach addresses the isolation objection by ensuring that beliefs are connected to reality.

Reliabilism: The Prominent Version of Externalism

• Belief Formation Sources:

  • Sources of Beliefs: Sense experience, reason, testimony, memory, etc.

  • Cognitive Processes: The specific processes (e.g., vision, expert testimony) that lead to the formation of beliefs.

Reliability Criterion:

• Core Principle: A belief is justified if it results from a cognitive process that reliably produces true beliefs.

• Examples:

  • Vision: Reliable for a normally-sighted person observing a well-lit object.

  • Testimony: Reliable when coming from an expert, unreliable when from a compulsive liar.

The Generality Problem

• Challenge in Specification:

  • Describing Processes: Cognitive processes can be described at various levels of generality (e.g., vision by a normally-sighted person vs. vision by a normally-sighted person in daylight while looking at an elm tree).

  • Impact on Reliability: Some descriptions might specify a reliable process, while others might not, affecting the justification status of the belief.

Implication:

• Need for Precision: To determine whether a belief is justified, one must specify the appropriate level of generality for the cognitive process.

The Truetemp Problem (Keith Lehrer)

• Scenario:

  • Mr. Truetemp: A person with a tempucomp device implanted in his brain that accurately reads the temperature and causes spontaneous true beliefs about it.

  • Unawareness: Truetemp is unaware of the device and its function.

Lehrer's Argument:

• Ignorance Issue: Truetemp’s ignorance about the source of his true beliefs renders those beliefs unjustified.

• Awareness Requirement: Lehrer concludes that a belief-forming process must not only be reliable but also that the believer must be aware of the reliability of the process for the beliefs to be justified.

The Extent of Human Knowledge

Sources of Knowledge

• Empirical Knowledge:

  • Perception and Senses: Empirical facts about the physical world are known through the senses (sight, hearing, smell, touch, taste).

  • Scientific Method: Science exemplifies empirical knowledge through data collection and experiments.

  • Everyday Perception: Most mundane knowledge about our environment is acquired through our sensory experiences.

Reasoning and Inference:

• Data Analysis: Scientists must analyze collected data to derive knowledge.

• Inferences: We draw inferences from sensory information to form knowledge.

• Abstract/Non-Empirical Knowledge: Knowledge of abstract or a priori facts relies on reasoning rather than sensory experience.

Intuition:

• Direct Access: Intuition is believed to provide direct access to a priori knowledge without needing empirical evidence.

Sustaining and Transmitting Knowledge

• Memory:

  • Retaining Knowledge: Memory enables us to retain knowledge over time.

  • Past Justification: We can remember something known in the past even if we forget the original justification for that knowledge.

• Testimony:

  • Knowledge Transmission: Knowledge can be passed from one person to another through testimony.

  • Trusted Sources: Belief in the truth of a proposition can be justified by the testimony of a trusted source.

Skepticism

• Core Idea: Skepticism is the view that we do not, or cannot, have knowledge, or that we know much less than we think we do.

Types of Skepticism:

• Local Skepticism:

  • Domain-Specific Doubts: Skepticism concerning specific areas such as mathematics, morality, or the external world.

  • Common Example: Skepticism about the external world is the most well-known form.

• Global Skepticism:

  • Universal Doubt: The belief that we cannot know anything at all.

Focus of Skepticism:

• Truth vs. Justification:

  • Truth Skepticism: The view that none of our beliefs are true.

  • Justification Skepticism: The view that none of our beliefs are justified (more common than truth skepticism).

Arguments for Skepticism

• General Strategy:

  • Challenging Knowledge Claims: Skeptics often question how we know what we claim to know.

  • Need for Argument: Simply questioning knowledge isn't enough; skepticism must be supported by robust arguments.

Prominent Arguments for External World Skepticism

• Argument from Illusion:

  • Premise: Our senses can deceive us, as evidenced by illusions and hallucinations.

  • Conclusion: If our senses are not always reliable, then we cannot trust them to provide knowledge about the external world.

• Brain in a Vat Argument:

  • Premise: It's possible that we are brains in vats, experiencing a simulated reality created by some external source.

  • Conclusion: If we cannot rule out this possibility, then we cannot be sure that our sensory experiences correspond to an external reality.

Cartesian Skepticism

• Skepticism: Descartes explores the possibility that all our beliefs might be unjustified due to systematic deception.

Key Points of Descartes' Argument

• Inaccuracy of Perceptions:

  • Sensory Deception: Our senses sometimes deceive us (e.g., optical illusions).

  • Dreams vs. Reality: We occasionally mistake dreams for waking experiences, making it difficult to distinguish between them.

• Evil Demon Hypothesis:

  • Possibility of Deception: It's conceivable that an evil demon is deceiving us, making all our experiences false.

  • Modern Version: The "brain-in-a-vat" scenario, where a brain connected to a computer in a vat receives simulated experiences, illustrates this deception.

Implications of the Argument

• Unjustified Beliefs:

  • False Beliefs: If some perceptions are false, then some of our beliefs based on these perceptions are also false.

  • Need for Distinction: To be justified in our beliefs, we need a reliable method to distinguish between true and false beliefs.

• Indistinguishability Problem:

  • Waking vs. Dreaming: No definitive signs distinguish waking life from dreams.

  • Trustworthy vs. Untrustworthy Beliefs: Similarly, no signs distinguish accurate beliefs from those caused by an evil demon or brain-in-a-vat scenario.

Conclusion of the Argument

• All Beliefs Unjustified: Since we cannot reliably distinguish between true and false beliefs, all our beliefs are potentially unjustified.

• Skepticism: This leads to a skeptical conclusion that we cannot know anything with certainty.

Descartes' Response to Skepticism in Later Meditations

• Method of Doubt:

  • Descartes uses hyperbolic doubt to question all beliefs, aiming to find something indubitable.

• Cogito Ergo Sum ("I think, therefore I am"):

  • Indubitable Belief: Descartes finds that while he can doubt everything, he cannot doubt that he is thinking and therefore exists as a thinking being.

  • Foundation for Knowledge: This becomes the foundational belief upon which he rebuilds his system of knowledge.

• Existence of God:

  • Proof of a Benevolent God: Descartes argues for the existence of a benevolent God who would not deceive him.

  • Reliability of Clear and Distinct Perceptions: If a benevolent God exists, then clear and distinct perceptions can be trusted as true.

• Distinguishing Truth from Falsehood:

  • Clear and Distinct Criterion: Descartes proposes that beliefs derived from clear and distinct perceptions are true.

  • Overcoming Skepticism: This provides a way to distinguish between true and false beliefs, countering the skeptical argument.

Humean Skepticism

• Core Idea:

  • Limitations of Perception: Our senses only provide information about how things appear at a given moment, not about how things actually are or about the unobserved parts of the universe.

  • Role of Reason: Reason is needed to extend our knowledge beyond immediate sensory experiences.

Hume's Critique of Reason

• Problem of Induction:

  • Inductive Reasoning: We often use past experiences to make generalizations about the future (e.g., the sun has risen every day, so it will rise tomorrow).

  • Hume's Critique: Hume argues that inductive reasoning lacks rational justification.

    • Just because something has happened in the past does not guarantee it will happen in the future.

    • There is no logical necessity connecting past and future events.

• Causal Inference:

  • Causation: We believe that one event causes another based on our experiences (e.g., striking a match causes it to light).

  • Hume's Critique: Hume contends that our belief in causation is not grounded in reason but in habit or custom.

    • We observe sequences of events and infer a causal connection, but this inference is not rationally justified.

    • We never perceive causation directly; we only see one event following another.

Key Points of Hume's Argument

• Perception Limits:

  • Immediate Sensory Data: Our senses only provide immediate and limited information about our current environment.

  • Beyond Immediate Perception: Knowledge about anything beyond what we currently perceive cannot be solely derived from the senses.

• Role of Habit and Custom:

  • Inductive Habit: Our expectation that the future will resemble the past is based on habit, not rational justification.

  • Customary Beliefs: Our beliefs about causation and the unobserved world are customary, formed through repeated associations rather than through reason.

• Skeptical Conclusion:

  • Unjustified Beliefs: Since reason cannot justify inductive reasoning or causal inferences, our beliefs about the external world beyond immediate perception are unjustified.

  • Persistent Skepticism: Even if we trust our senses, we face skepticism regarding any knowledge claims extending beyond our immediate sensory experiences.

Language and Meaning

• Language is essential for expressing and communicating knowledge.

• Philosophical inquiry into language explores how meaning is constructed and understood.

• Meaning: The significance or interpretation of words and sentences. Theories of meaning include:

  • Referential Theory: Words refer to objects or concepts in the world.

  • Use Theory: Meaning is derived from how words are used in practice (Ludwig Wittgenstein).

  • Truth-Conditional Semantics: The meaning of a sentence is given by the conditions under which it is true.

Truth, Coherence, Correspondence, and Pragmatism

• These theories offer different criteria for evaluating the truth of statements:

• Correspondence Theory: A statement is true if it corresponds to a fact or reality.

• Coherence Theory: A statement is true if it coheres with a consistent system of interconnected beliefs.

• Pragmatic Theory: A statement is true if it is useful and works in practical terms.

Grammarian Philosophies: A Classical Indian Approach

• Classical Indian epistemology provides rich insights into the nature of knowledge and the role of language:

• Nyaya School: Emphasizes logical analysis, debate, and the four means of acquiring knowledge: perception, inference, comparison, and testimony.

• Buddhist Epistemology: Focuses on perception and inference, with a critical examination of the self and the nature of reality. Key figures include Dignaga and Dharmakirti.

• Mimamsa and Vedanta: Explore the role of Vedic texts and direct experience in understanding reality. Mimamsa emphasizes ritual and dharma, while Vedanta focuses on metaphysical questions about Brahman and the self.

Challenges to Knowledge and Confirmation of Knowledge

Realism and Skepticism

• Realism: The view that an external reality exists independently of our perceptions. Realists argue that we can know the world through our sensory experiences and rational inferences.

• Skepticism: Doubts the possibility of certain knowledge. Skeptics argue that our senses and reasoning are fallible, and thus, we can never achieve absolute certainty.

Arguments from Illusion and Mysticism

• Illusion: Perceptual errors that challenge the reliability of sensory knowledge. For example, a stick appears bent when partially submerged in water.

• Mysticism: Claims knowledge through direct, often ineffable, spiritual or transcendental experiences. Mystical knowledge is seen as beyond ordinary sensory or rational understanding.

Subjectivism and Objectivism

• Subjectivism: The view that knowledge is influenced by individual perspectives and experiences. Truth and justification are seen as relative to the subject.

• Objectivism: The view that knowledge and truth exist independently of individual beliefs or perceptions. There are objective standards for justification and truth.

Causal Theory, Idealism, Phenomenalism, Perspectivism

Causal Theory

• The causal theory of knowledge suggests that beliefs are justified when they are caused by the relevant facts or states of affairs in the right way.

• For instance, seeing a tree and believing that there is a tree because you see it.

Idealism

• Idealism posits that reality is fundamentally mental or immaterial.

• Major proponents like George Berkeley argue that objects only exist as perceptions in our minds, and there is no material substance underlying them.

Phenomenalism

• Phenomenalism claims that physical objects do not exist independently of our sensory experiences.

• Instead, objects are logical constructions from sensory experiences.

• This view is closely associated with philosophers like John Stuart Mill.

Perspectivism

• Perspectivism, associated with Friedrich Nietzsche, suggests that all knowledge is from a particular perspective and that there are no objective truths.

• Knowledge and truth are seen as contingent on individual or cultural perspectives.

Theories of Justification

• Justification is the process or reasons that support our beliefs and distinguish knowledge from mere belief.

• Various theories include:

• Foundationalism: Beliefs are justified based on basic, self-evident truths or foundational beliefs that do not require further justification.

• Coherentism: Beliefs are justified by their coherence with other beliefs in a mutually supportive system. There are no foundational beliefs, but rather a web of interconnected beliefs.

• Reliabilism: Beliefs are justified if they are produced by reliable cognitive processes or methods that generally lead to true beliefs.

• Virtue Epistemology: Justification depends on the intellectual virtues of the knower, such as open-mindedness, intellectual courage, and intellectual humility.

Knowledge Around the World

Access to Knowledge

• Access to knowledge varies widely across the globe, influenced by factors such as socioeconomic status, education systems, cultural norms, and political regimes.

• The digital divide highlights disparities in access to information and technology.

Knowledge and Technology

• Technology profoundly impacts how knowledge is created, shared, and accessed.

• The internet, digital media, and artificial intelligence are transforming the landscape of knowledge, raising issues of information overload, digital literacy, and the ethics of technology use.

Knowledge and Power

• Knowledge is closely linked to power structures. The control and dissemination of knowledge can reinforce or challenge social inequalities.

• The concept of "knowledge is power" underscores how those who control knowledge can influence societal norms, policies, and governance.

Unit 4: Ethics

Deontological Theories 

Kantian Ethics (Rationalist approach)

• Immanuel Kant was a German philosopher who is considered one of the most important figures in Western philosophy. 

• He developed the concept of transcendental idealism and is known for his works on ethics, epistemology, and metaphysics. 

• Kant's influential works include "Critique of Pure Reason" and "Groundwork of the Metaphysics of Morals."

The three types of categorical imperatives are:

1. Universalizability: Act only according to the maxim that you can at the same time will to become a universal law.

2. Humanity: Always treat humanity, whether in yourself or others, as an end in itself and never merely as a means.

3. Kingdom of Ends: Act as if you are a member of a kingdom of ends, where rational beings are both the authors and subjects of universal laws.

The Phenomenal realm vs the nominal realm

• Phenomenal

  • Kant's phenomenal realm refers to the world of appearances or the realm of experience.

  • According to Immanuel Kant, our knowledge is limited to the phenomenal realm, where we perceive and interpret things through our senses and mental faculties.

  • This realm is contrasted with the noumenal realm, which is inaccessible to human understanding. 

  • Kant argued that our perception of reality is shaped by our mental structures and that we can never know things as they are in themselves.

  • Associated with animals.

• Nominal

  • Kant's nominal realm refers to the realm of appearances or phenomena, as opposed to the noumenal realm of things-in-themselves. 

  • According to Kant, our knowledge is limited to the phenomenal realm, and we can never know things as they are in themselves. 

  • The nominal realm is the world as it appears to us, shaped by our senses and mental faculties. It is the realm in which we can have knowledge and make meaningful judgments.

  • Associated with Gods and angels.

Moral rationalism

• Moral law - Observable through reason and doesn’t depend on empirical/tangible evidence

• Good will - A will that acts for the sake of duty for the greatest good. Central to Kanian ethics.

• Autonomy - The capacity of an individual to make a rational choice independently.

Utilitarianism 

• Utilitarianism - an ethical theory that focuses on maximizing overall happiness or well-being for the greatest number of people. It suggests that actions should be judged based on their consequences and the pleasure or happiness they produce. The goal is to achieve the greatest net benefit for society.

• The principle of utility

  • The choosing of the most overall happiness for the greatest number

  • Doesn’t need to follow the universal law

• Rule utilitarianism - Mill

  • Definition: a moral theory that states that an action is morally right if it conforms to a rule that, if universally followed, would lead to the greatest overall happiness or utility for everyone involved. It focuses on the consequences of following certain rules rather than the consequences of individual actions.

  • Difference from act Utilitarianism is that act Utilitarianism is for overall happiness whereas rule utilitarianism is for the given group which then is laid out into a framework with rules to follow.

• Act utilitarianism - Bentham

  • Definition: an ethical theory that states an action is morally right if it produces the greatest amount of overall happiness or utility for the greatest number of people. It focuses on the consequences of individual actions rather than following predetermined rules or principles.

  • Hedonic calculus: A concept introduced by philosopher Jeremy Bentham. It is a method of measuring pleasure and pain to determine the moral value of an action. It involves assessing the intensity, duration, certainty, propinquity, fecundity, purity, and extent of pleasure or pain that may result from an action. The goal is to maximize pleasure and minimize pain to make ethical decisions.

• Preference Utilitarianism - Singer

  • The ethical theory where they decide to maximize the desires or preferences of everyone

Virtue Ethics - Aristotle and Macintyre 

• Aristotle is widely recognized as the main philosopher associated with virtue ethics, a branch of ethical theory that emphasizes the importance of cultivating virtuous character traits to lead a good and fulfilling life. Aristotle's emphasis on the importance of character and moral development has had a lasting impact on ethical thought and continues to be studied and debated by philosophers and scholars to this day.

• Virtue Ethics is an ethical theory that focuses on the character of an individual rather than the consequences of actions. It emphasizes developing good habits and virtues to lead a moral life.

Concepts

• Eudaimonia, (translated as happiness) is the ultimate goal of a human’s life. This can be achieved by living virtuously and acting according to reason.

• Just because you do a virtuous act does not make you virtuous, it must be coming from one’s character and decided on their own.

• The Doctrine of the Mean is the way to behave morally by finding a balance between excessive behavior and deficient behavior.

• Virtue ethics are not innate but it was developed through practice and conscious effort.

• There are two types of virtues:

  • Moral virtues, which oversee how we interact with others.

  • Intellectual virtues, which guide our own understanding.

Criticisms

• Overemphasis on character traits

• Lack of clear guidelines for action, especially towards moral dilemmas

• Subjectivity in determining virtues

• Ignoring the consequences of actions

• Moral relativism as virtues would be different, varying in communities.

Alasdair MacIntyre 

• Maclntyre is a highly respected and influential philosopher who has made significant contributions to the field of virtue ethics.

• MacIntyre's work emphasizes the importance of cultivating virtuous character traits as essential components of living a good and fulfilling life. He delves into the complexities of moral philosophy and explores how virtues play a crucial role in guiding ethical decision-making. 

Ethical egoism and self interest 

• Ethical Egoism is a normative theory that suggests individuals should act in their own self-interest. It asserts that individuals ought to prioritize their own well-being above others.

Additional nuances towards ethical egoism

• The idea that humans are inherently self-interested, directing aligning to the moral actions with human nature

• The comparison between what will be the most beneficial to one's self in the long term

Criticisms to ethical egoism

• Differences in interests, in the case where pursuing self-interest would result in harm for others.

• The promotion of personal gain over collective well-being could undermine the social fabric.

Tensions from ethical egoism

• The weighing of personal needs against the personal needs of others, understanding that ethical egoism could cause a conflict with what's right.

• For example: Questing equitable distributions of medical treatments, is a rich man more deserving of treatment than a regular civilian?

• Relevant Philosophical theories that address this tension:

  • Utilitarianism

  • Kantian Ethics

Ayn Rand 

• Rand was a Russian-American writer and philosopher known for her novels promoting individualism and capitalism, such as "Atlas Shrugged" and "The Fountainhead". She is considered one of the biggest advocates for this theory. 

• Her main points are:

  • Individuals have the right to their life, liberty and property and these rights should be protected by the government. Ethical egoism is consistent in the recognition and respect for individual rights

  • Rejection of altruism. Which is the practice of selflessly acting for the benefit of others without expecting anything in return.

Meta-ethics 

• Meta-ethics is a study of ethical language, exploring the moral lesson's semantics and logical framework. This closely links sociology and psychology as well as looks into which framework an individual will use to respond to what is “right” or “wrong” while engaging in ethical debates.

Cognitivism

• Cognitivism is a learning theory that focuses on the internal mental processes involved in learning, such as problem-solving, memory, and understanding. It emphasizes the importance of how the brain processes information for learning to occur effectively. Cognitivists will engage in ideas that could be seen as morally correct or incorrect.

• Sam Harris

  • Arguing how there is a relationship between human values and science

  • Rock example: we don’t care about rocks and they aren’t exposed to suffering, this is a fact.

  • You are still concerned about consciousness and its changes

  • There are truths to be known about how human communities thrive and these truths often construct values.

  • Personality is a product of the brain

  • We call it religious and something religious or spiritual but it could be something that’s just stored in a different part of the brain.

Emotivism - A J Ayer

• Emotivism is a meta-ethical view that ethical statements express emotions or attitudes rather than objective truths. It suggests that moral judgments are based on feelings rather than facts.

• Contributing philosophers: A J Ayer “when two people disagree a fact, there would be a way to resolve it but when two people disagree over a judgment there isn’t a way to resolve it”

• The “Boo Hurray Theory” - a theory that some moral instances do not have a truth value but can be expressed through the feelings of the speaker (hence the boo and hurray). For example, the idea that murder is wrong is the same thing as boo murder.

Intuitionism - G E Moore

• Intuitionism is a philosophical approach that illustrates how moral truths are discovered through intuition or insight rather than through logical deduction. In this perspective, it shows that some morals are self-evident, which doesn’t require any justifications.

• Some criticisms are how subjective this theory is, it's not all cases where some morals are universally agreed upon.

Prescriptivism - R M Hare

• Prescriptivism is an approach to language that emphasizes following established rules and norms to maintain linguistic correctness and clarity. Let’s say if someone says animal cruelty is wrong to me, they are trying to enforce the same morals towards me.

Moral Judgements - A higher being 

Divine Command Theory

• Definition: The moral rightness by the commands of a divine being, the actions only morally right when God says it is.

Natural Law - Aquinas

• The idea that humans are rational, and should conform or stick by these moral values -> “natural law”. It is derived from our natural human instincts and not from values cultivated as a society. 

• 3 main rules by Aquinas: 

  • Humans must do good deeds and avoid sinning. 

  • Survival and procreation are core human values.

  • Natural laws set by the government are positive laws.

Applied Ethics 

Euthanasia

• Euthanasia is the practice of intentionally ending a life to relieve pain and suffering.

Key definitions

• Voluntary euthanasia - when a person requests (or chooses to) to end their life to relieve pain. 

• Non-voluntary euthanasia - when the permission from the patient stated unclearly. 

• Assisted Suicide - when suicide is done with the aid of another person (typically physician) 

• Involuntary euthanasia - a practice on euthanasia to a person without permission or who does not want to die. 

• Active euthanasia - is done through an action (painkillers overdose) 

• Passive euthanasia - is death bought by omission (leaving the patient to die)

Ethical Issues

• Whether the patient has the autonomy to make this personal choice of ending its own life

• The (mostly religious) views that life is valuable and a human should not end a life that God created

• The idea that euthanasia can cause a slippery slope of non-consensual euthanasia or the promotion of the idea that life isn’t valuable

Abortion

• The medical product involves terminating a pregnancy through the process of removing an embryo or fetus.

Ethical issues

• Seeing a moral balance between the rights of the fetus and the rights of the mother

• The stage of the fetus that can be considered for it to be alive -> Gives it human rights

• Whether a fetus should be granted personhood

Genetic Engineering

• The process of unnaturally altering one’s organism’s genome using biotechnologies could be towards humans, animals or plants.

Ethical issues

• The unknown long-term effects on the ecosystem and the human’s health

• To what extent did the person/animal agree to this consensus?

• Raises concerns about healthcare equality

Unit 5: Philosophy and Contemporary Society (IB)

• This branch of philosophy examines how philosophical concepts shape and respond to modern societal issues. It explores multiculturalism, liberty, rights, technology, and media, providing critical perspectives on how these factors influence contemporary life.

1. Multiculturalism

• Multiculturalism refers to the coexistence of diverse cultural groups within a society and the philosophical, ethical, and political challenges it presents.

1.1 The Concept of Culture

• Culture encompasses beliefs, customs, traditions, language, and social behaviors that define a group of people.

• Philosophers explore whether cultures are static or evolving, and how they interact in diverse societies.

• Questions arise about cultural appropriation, identity, and assimilation in multicultural societies.

• Debates include cultural relativism (the idea that all cultures are equally valid) vs. universalism (the belief in shared human values).

  • Cultural Relativism → The belief that moral values, practices, and beliefs are relative to each culture and should be understood within their own context.

    • Key argument: No single culture has the authority to judge another’s customs, as morality is shaped by cultural traditions.

    • Example: Some cultures practice arranged marriages, while others emphasize individual choice in relationships. Cultural relativists argue that both should be respected without imposing external values.

    • Criticism: It can justify harmful practices (e.g., child marriage, discrimination) by labeling them as "cultural norms."

  • Universalism → The belief that certain fundamental values and rights apply to all human beings, regardless of culture.

    • Key argument: Some moral principles, like human rights, transcend cultural differences and should be upheld globally.

    • Example: The Universal Declaration of Human Rights asserts that freedom of speech and gender equality should be upheld worldwide.

    • Criticism: Universalism can be seen as ethnocentric or imperialistic, imposing one culture’s moral standards on others.

  • Ongoing Debate:

    • Should international laws enforce human rights even if they conflict with local traditions?

    • Can there be a balance between respecting cultural diversity and protecting fundamental human rights?

1.2 Treatment of Minority or Marginalized Groups

• Examines historical and systemic discrimination against minority groups based on race, ethnicity, gender, sexuality, religion, or disability.

• Considers affirmative action policies whether they promote equality or cause reverse discrimination.

• Discusses social justice theories (e.g., John Rawls’ Theory of Justice) in relation to the fair treatment of minorities.

• Addresses the balance between protecting minority rights and maintaining social unity.

1.2.1 John Rawls’ Theory of Justice Description

• John Rawls (1921–2002) proposed a theory of justice based on fairness and equality, emphasizing that social and economic inequalities should be arranged to benefit the least advantaged in society.

1.2.2 Key Principles of Rawls' Theory of Justice

• The Original Position and the Veil of Ignorance

  • Rawls asks us to imagine a hypothetical scenario where people design the rules of society without knowing their own status (race, gender, wealth, abilities).

  • This "veil of ignorance" ensures that rules are created fairly, as no one would create laws that disadvantage themselves if they could end up in any position in society.

  • Application to Minority Rights:

    • If people didn't know whether they would be part of a minority group, they would likely create laws that protect all groups equally.

    • Supports policies like equal rights protections, anti-discrimination laws, and affirmative action.

• The Two Principles of Justice

  • 1st Principle: Equal Basic Liberties

    • Every person should have equal fundamental rights, such as freedom of speech, religion, and political participation.

    • These rights must apply equally to all, including minorities who may face discrimination.

  • 2nd Principle: The Difference Principle

    • Social and economic inequalities are only justifiable if they benefit the least advantaged.

    • Example: Higher taxes on the wealthy to fund public services (like education and healthcare) that benefit lower-income and marginalized groups.

    • Supports programs aimed at reducing systemic disadvantages (e.g., scholarships for underprivileged students, workplace diversity programs).

1.3 Tolerance

• Tolerance refers to the willingness to accept or respect different opinions, behaviors, and beliefs.

• Philosophical perspectives explore whether tolerance has limits, such as in cases of hate speech or extremism.

• John Stuart Mill’s Harm Principle suggests that freedom should be allowed unless it harms others.

• Debates exist on how to balance tolerance with secularism, religious freedom, and national identity.

1.3.1 John Stuart Mill’s Harm Principle

• John Stuart Mill (1806–1873), a philosopher and political theorist, introduced the Harm Principle in his book On Liberty (1859). This principle argues that individuals should be free to act as they wish, as long as their actions do not harm others.

1.3.2 Key Aspects of the Harm Principle

• Freedom of the Individual

  • Mill believed that personal freedom is essential for human progress and happiness.

  • People should be free to express their opinions, make their own life choices, and engage in activities of their choosing—as long as they do not cause harm to others.

• Definition of "Harm"

  • Harm refers to actions that infringe on the rights, safety, or well-being of others.

  • Personal offense or disagreement does not count as harm (e.g., someone expressing a controversial opinion is not considered harmful).

  • Examples of harm:

    • Violence, theft, fraud, or deception → Directly harms others.

    • Spreading false medical advice → Can cause real harm by misleading people.

    • Drunk driving → Puts others at risk of injury or death.

• Self-Regarding vs. Other-Regarding Actions

  • Self-regarding actions → Only affect the individual (e.g., choosing an unhealthy lifestyle, personal religious beliefs). These should not be restricted.

  • Other-regarding actions → Affect others in harmful ways (e.g., inciting violence, polluting the environment). These may be restricted by law.

• Application to Freedom of Speech

  • Mill argued that free speech should be protected, even if it is offensive or unpopular.

  • However, speech that directly incites violence or harm (e.g., threats, incitement to riot) can be restricted.

  • Example:

    • Saying "I dislike the government" is protected.

    • Saying "Let’s attack government officials" may be restricted under the Harm Principle.

• Limits of Government and Society

  • Mill was against paternalism—the idea that the government should restrict people's freedoms "for their own good."

  • He argued that adults should be allowed to make their own decisions, even if they are risky, as long as they do not harm others.

  • Example:

    • A person smoking cigarettes should not be legally punished because it mainly harms them.

    • However, smoking in a crowded public space may be restricted because secondhand smoke harms others.

2. Liberty and Rights

• This section explores the nature of freedom, the distinction between different types of liberty, and the philosophical foundations of human rights.

2.1 Positive and Negative Liberty

• Negative liberty (Isaiah Berlin) → Freedom from external interference (e.g., freedom from government control).

• Positive liberty (Isaiah Berlin) → Freedom to achieve self-mastery and personal fulfillment (e.g., access to education, healthcare).

• Tensions arise in government policies—should the state provide welfare (positive liberty) or minimize interference (negative liberty)?

2.2 Legal and Human Rights

• Legal rights → Rights granted and protected by the law (e.g., right to property, right to vote).

• Human rights → Universal moral rights, regardless of legal recognition (e.g., right to life, freedom from torture).

• Explores debates about whether human rights are universal or culturally relative.

• Examines philosophical justifications for human rights, including natural law (John Locke) and social contract theories (Rousseau, Hobbes).

2.3 Censorship and Freedom of Information

• Censorship → The suppression of speech, communication, or access to information by governments, corporations, or institutions.

• Freedom of information → The right of people to access and distribute knowledge freely.

• Key debates:

  • Should hate speech be restricted, or does this violate freedom of expression?

  • Is internet censorship justified for national security or harmful content?

  • Should governments regulate fake news and misinformation?

2.4 Terrorism and Political Violence

• Examines the ethics of political violence—can violence ever be justified in pursuit of political or ideological goals?

• Philosophical views:

  • Just War Theory (Augustine, Aquinas) → Violence is permissible under strict conditions.

  • Pacifism (Gandhi, Tolstoy) → Violence is never justified.

• Debates on state responses:

  • Does counterterrorism threaten civil liberties?

  • Should governments engage in negotiations with terrorists?

3. Technology and Media

• This section explores the role of technology and media in shaping contemporary society, ethics, and human behavior.

3.1 Role of Technology in Contemporary Society

• Technology drives scientific advancement, economic growth, and social change.

• Raises ethical concerns about AI, automation, surveillance, and genetic engineering.

• Philosophers debate technological determinism (technology shapes society) vs. social constructivism (society shapes technology).

3.2 Impact of Technology on Contemporary Society

• Positive impacts:

  • Improved healthcare, communication, and efficiency in industries.

  • Democratization of knowledge through the internet.

• Negative impacts:

  • Job displacement due to automation and AI.

  • Digital divide—inequality in access to technology.

  • Privacy concerns—government and corporate surveillance.

3.3 The Media in Contemporary Society

• The media serves as a source of information, entertainment, and political influence.

• Key philosophical concerns:

  • Media bias and propaganda—Do the media shape public opinion unfairly?

  • Social media and democracy—Do platforms like Twitter and Facebook promote freedom or spread misinformation?

  • Surveillance capitalism (Shoshana Zuboff)—How do companies profit from personal data?

  • Echo chambers—Does media reinforce biases instead of encouraging critical thinking?

Arguments for the Existence of God

A. Cosmological Argument

• Key Proponents: Thomas Aquinas, Al-Ghazali (Kalam), William Lane Craig

• Summary: Everything that exists has a cause; the universe exists, therefore, the universe has a cause, which is identified as God.

• Types:

  • Kalam Cosmological Argument: Everything that begins to exist has a cause; the universe began to exist, therefore, the universe has a cause.

  • Aquinas’s Five Ways:

    1. Argument from Motion

    2. Argument from Causation

    3. Argument from Contingency

    4. Argument from Degrees of Perfection

    5. Argument from Final Cause or Teleology

• Criticisms:

  • Infinite Regress: Some argue that an infinite regress of causes is possible.

  • Big Bang Theory: Provides a natural explanation for the origin of the universe.

  • Fallacy of Composition: Assuming what is true of the parts is true of the whole.

  • Assumption of a Personal God: The first cause need not be a personal, theistic God.

B. Teleological Argument (Design Argument)

• Key Proponents: William Paley, Intelligent Design Advocates

• Summary: The complexity and order of the universe suggest a designer, much like a watch implies a watchmaker.

• Examples:

  • Fine-Tuning Argument: The precise conditions that allow life in the universe indicate design.

  • Irreducible Complexity: Some biological systems are too complex to have evolved entirely through natural selection.

• Criticisms:

  • Natural Selection and Evolution: Darwin’s theory provides a naturalistic explanation for complexity.

  • Poor Design: Instances of suboptimal design in nature.

  • Multiple Designers: The argument does not specify the nature or number of designers.

C. Ontological Argument

• Key Proponents: Anselm of Canterbury, René Descartes, Alvin Plantinga (modal version)

• Summary: The concept of God as the greatest conceivable being implies God's existence, as existence is a necessary attribute of the greatest being.

• Versions:

  • Anselm’s Version: God is defined as a being than which nothing greater can be conceived, and such a being must exist in reality as well as in the mind.

  • Descartes’ Version: Existence is a perfection, and since God possesses all perfections, God must exist.

  • Plantinga’s Modal Ontological Argument: Uses modal logic to argue that if God's existence is possible, then God necessarily exists.

• Criticisms:

  • Gaunilo’s Island: The same logic could be used to prove the existence of a perfect island, which is absurd.

  • Kant’s Critique: Existence is not a predicate or property that makes something greater.

  • Logical Problems: Questions about the coherence of the concept of a maximally great being.

D. Moral Argument

• Key Proponents: Immanuel Kant, C.S. Lewis, William Lane Craig

• Summary: The existence of objective moral values and duties points to a moral lawgiver, identified as God.

• Types:

  • Argument from Moral Order: The best explanation for the moral order is the existence of a moral lawgiver.

  • Argument from Moral Experience: Our experience of moral obligations implies a transcendent source.

• Criticisms:

  • Moral Relativism: Moral values can vary between cultures and individuals.

  • Euthyphro Dilemma: Are actions good because God commands them, or does God command them because they are good?

  • Secular Ethics: Moral values can be grounded in human nature and rationality.

Arguments Against the Existence of God

A. Problem of Evil

• Key Proponents: Epicurus, David Hume, J.L. Mackie

• Summary: The existence of evil and suffering is incompatible with an omnipotent, omnibenevolent God.

• Types:

  • Logical Problem of Evil: The existence of evil logically contradicts the existence of an all-good, all-powerful God.

  • Evidential Problem of Evil: The amount and kinds of evil provide evidence against the existence of God.

• Responses:

  • Free Will Defense: Evil is a result of human free will, which is necessary for moral goodness.

  • Soul-Making Theodicy: Suffering helps develop virtues such as courage and compassion.

  • Greater Good Defense: God allows evil because it leads to a greater good that outweighs the evil.

B. Evidential Problem of Evil

• Key Proponents: William Rowe

• Summary: Argues that the sheer amount and nature of unnecessary suffering provide strong evidence against the existence of God.

• Examples: Cases of intense suffering that seem pointless or gratuitous.

• Responses:

  • Skeptical Theism: Humans cannot understand God’s reasons for allowing suffering.

  • Greater Good Arguments: Suffering may be part of a divine plan beyond human comprehension.

C. Divine Hiddenness

• Key Proponents: J.L. Schellenberg

• Summary: Argues that if a loving God existed, God would make His existence more evident to people.

• Examples: Non-resistant non-believers, who seek God but do not find Him.

• Responses:

  • Free Will and the Value of Faith: God’s hiddenness preserves human free will and the value of faith.

  • Divine Reasons for Hiddenness: There may be greater reasons for God’s hiddenness that humans cannot comprehend.

Religious Experience

  • Cultural Influence: Religious experiences are often influenced by cultural and religious backgrounds.

  • Verifiability: Subjective experiences are difficult to verify objectively.

Faith and Reason

• Fideism: The view that religious belief relies solely on faith rather than reason.

  • Proponents: Søren Kierkegaard, Blaise Pascal.

  • Criticisms: Potential conflict between faith and rational inquiry.

• Aquinas’s View: Harmony between faith and reason, where faith seeks understanding.

  • Proponents: Thomas Aquinas, Augustine of Hippo.

  • Criticisms: Challenges in reconciling faith with scientific and philosophical reasoning.

• Kierkegaard’s Leap of Faith: Faith involves a personal, subjective commitment beyond rational evidence.

  • Key Ideas: The paradox of faith, the absurd, subjective truth.

Unit 8: IB: Political Philosophy (HL)

Flashcard Set: https://knowt.com/flashcards/a34e565f-6f7e-4a4d-8d52-f7ad5ed4d471

Political Philosophy: This is the area of philosophy that fixates on the study of people in societies, and the rights and obligations they have, as well as the needs of said people for justice and liberty in the societies they live in.

This theme explores questions such as the following:

• Are freedom and equality compatible?

• Can justice be an ideal as well as a process?

• Are human rights inalienable and universal?

Civil Society, The State, and Government

The distinctions between state, nation, government, and civil society:

• State vs. Nation: a state is a political entity, with a territory, while a nation is a social and cultural body. A state can have multiple nations, such as the UK, but a nation cannot have its own state, i.e Kurds.

• Government vs. State: The government is the establishment through which a state can exercise its authority. While the state is a permanent body, the government can change, such as during elections or coups.

State: A political entity with a centralized government that has the power to govern the territory and its population.

• States hold sovereignty, which is defined as having supreme power over its territory, while also being recognized by other states.

• Some other characteristics a state has are: defined geographical boundaries, a population, government, and a monopoly on the use of force within its territory.

Nation: This is defined as a group of people who share common cultural, ethnic, linguistic, social, or historical connections. A nation will have the following characteristics:

• Identity: A shared sense of belonging among the population

• Culture: Common cultural practices and traditions

• History: A shared historical background

• A desire for political autonomy

Government: The system/group of people governing an organized community, usually a state. A government has the following characteristics:

• Institutions: A government will have many branches (i.e executive, judicial, and legislative branches)

• Authority: A government has the ability to make and enforce laws

• Legitimacy: A government will gain authority from laws, a constitution, or with the consent of the governed population

Civil Society: This term refers to the collection of non-governmental organizations, and associations that represent the interest and voice of the citizens. A civil society will have the following characteristics:

• Organizations: This includes NGOs, community groups, trade unions, etc.

• Engagement: This is to encourage citizen participation in public life and governing outside of the official political system.

• Advocacy: The promotion of social values, human rights, and political accountability

Social Contract Theories of the state of nature, civil society, and forms of government

Social contract theories refer to the philosophical frameworks that observe the origin of society, and the validity of a state’s influence on an individual. The key philosophers in this concept were: Thomas Hobbes, John Locke, & Jean Jacques Rousseau.

Thomas Hobbes:

• Described the state of nature as a pre-political atmosphere, where there is no common authority that rules over the population and enforces laws. In this state, individuals are motivated by self-preservation, leading them to be in constant conflict.

• The forming of a civil society occurs when individuals will unanimously agree to surrender their freedom to an authority in exchange for order and safety, and to maintain peace.

• Hobbes was an advocate for an absolute monarchy form of government, where the sovereign’s power is justified as long as it maintains order and protects the lives of its subjects.

John Locke:

• Believed that individuals are rational beings who are fit to recognize their natural rights (“life, liberty, and property”), but his state of nature lacks laws and reliable enforcement.

• The forming of a civil society occurs when, to protect their natural rights, individuals agree to create a government that gets power from the consent of the governed.

• Locke favored a representative government with a separation of powers, in order to prevent absolutism; if the government failed to protect natural rights, the citizens would have the right to revolt.

Jean-Jacques Rousseau:

• Rousseau viewed the state of nature as a peaceful atmosphere where individuals lived in harmony and were all free and equal. However, introducing things like private property could lead to corruption.

• To overcome the corruption and injustice created by private property, individuals would agree to form a civil society, governed by a general will (which represents the shared interests of all of the citizens).

• Rousseau believed in a direct democracy where all citizens actively participated in making laws.

Revolution and Anarchism

• Revolution: an often rapid change in political power and societal structures, and they usually happen through mass mobilization, sometimes involving violence. The key characteristics of a revolution involve: radical change, mass mobilization, and ideological motivations.

  • Notable Theories/Thinkers

    • Karl Marx: He believed that revolutions will always occur in capitalist societies due to classism between the bourgeoisie (capitalists) and the proletariat (workers).

• Anarchism: A political philosophy that supports a stateless society, completely based on voluntary cooperation, mutual aid, and no hierarchical authority. The key principles of anarchism are the rejection of the state, self-managed communities, and opposition to all forms of hierarchical authority.

Authority, Sovereignty, Power, and Corruption

Authority: This term refers to the legitimate right to exercise power, often held by an individual or institution.

Sovereignty: This refers to the main/top authority within a territory, the full influence a governing body will have to govern itself without outside influence.

Power: The ability to either strongly influence or control the behavior of people; power can be both legitimate or illegitimate.

Corruption: The abuse of power for private gain, disrupting social order and leading to economic costs.

Forms of Government:

One-Party Democracy: When a single political party is in control of the government; other parties may exist but they have no real possibility of gaining authority.

• Pros: Stability in the making of laws, as well as easy decision-making with the lack of gridlock.

• Cons: Potential for abuse of power, lack of accountability.

Multiparty Democracy: A form of government where multiple political parties will compete for power through fair election processes. This form typically includes a separation of powers and checks and balances.

• Pros: Representation of diverse views, greater transparency and accountability.

• Cons: Chance of political instability and frequent changes in the governing system; decision making can take a longer time.

Oligarchy: A form of government where power is held in the hands of a small group of people, often based on wealth, family ties, or militarized control.

• Pros: Efficient decision-making, stability and continuance in government

• Cons: Lack of diverse representation, potential of corruption and social injustice

Monarchy: A form of government where an individual (the monarch) has the ruling power, usually by their hereditary right.

• Pros: Continuity in leadership

• Cons: Potential for abuse of power, limited participation in governing

Authoritarian and Totalitarian Rule: Authoritarianism is a form of government that is defined by a strong central power and limited political freedom. Totalitarianism is a more extreme form of authoritarianism where the state attempts to seek control of every aspect of public and private life, usually through intense surveillance and propaganda.

• Pros: Rapid decision-making and policy implementation

• Cons: Severe restrictions on freedom and human rights, high potential for abuse of power.

Tribalism: A form of government based on tribal affiliations and structures, and this is usually found in societies where tribes are the main social units, so governing usually occurs using traditional leaders and customs.

• Pros: Strong sense of community, decisions are often made while considering the tribe’s well being and culture.

• Cons: Can lead to conflict and separation between tribes; lack of the formal frameworks needed for modern governance.

Theocracy: A type of government where religious leaders control the state, with the laws being based on religious doctrine.

• Pros: Decisions are influenced strongly by religious principles and values, and can give a strong sense of moral ethics.

• Cons: Limited religious pluralism, risk of discrimination among those of different faith, potential for conflict between religions and sects.

Ideologies of Government:

Liberalism:

• Core Principles: This ideology emphasizes individual freedoms, rights, and equality. It also advocates for democracy, free markets, and limited government interaction in the economy.

• Key Theorists: John Locke, John Stuart Mill

• Criticisms: Can lead to severe economic inequality, emphasizing individualism might neglect a sense of community

Conservatism

• Core Principles: Emphasizes tradition, social stability, and maintaining established institutions. Advocates for gradual change, and believes in hierarchy and authority.

• Key Theorists: THomas Hobbes, Edmund Burke

• Criticisms: Can be opposed to needed social changes, potential for authoritarianism, prioritization of traditional over individual freedoms.

Marxism

• Core Principles: Analyzing society based on class struggling and conflicts between the working and ruling class, advocates for the establishment of a classless society, with no private property. This ideology also believes in the impending overthrow of capitalist societies through revolting, and emphasizes collective ownership and redistribution of wealth.

• Key Theorists: Karl Marx, Vladimir Lenin

• Criticisms: Historically, Marxist societies often led to authoritarian societies. Additionally, it is difficult to prevent the rise of elite classes and maintain a classless state. The economy in a Marxist society is inefficient, and lacks productivity.

Socialism

• Core Principles: Advocacy for social ownership and democratic control of the means of production, emphasizes reducing economic inequality and providing social safety nets. This ideology supports comprehensive welfare systems, public services, progressive taxation.

• Key Theorists: Karl Marx, Friedrich Engels

• Criticism: Can lead to excessive government control and bureaucracy, potential for inefficiency and lack of innovation, balancing individual freedoms with collective goals.

Civil Duties: This term shows a range of responsibilities that individuals owe to their community, society, and state. These duties include:

• Obeying the Law: Following the laws that are established by the government.

• Paying Taxes: Contributing in a financial manner to the state to fund public services.

• Jury Duty: Participating in the judicial process by serving on juries to ensure fair trials.

• Voting: Participating in the democratic process by voting in elections.

• Military Service: Defending the country if needed, through voluntary service or conscription.

• Promoting Social Justice: acting to ensure fairness, equality, and justice within society.

Ethical Foundations of Civil Duties

1. Utilitarianism: promoting actions that maximize well being, and contribute to the greatest good for the greatest population

2. Deontology: Adherence to moral duties and rules.

3. Social Contract Theory: states that individuals consent to form a society and abide by its rules in exchange for protection and benefits.

The Analogy of state as a family/clan: This analogy shows how the relationships within a family can be similar to those of a state.

• Just as parents have authority within a family, government officials will hold the authority in a state.

• Family members hold obligations to each other, just as citizens have duties to their state to obey laws, pay taxes, and contribute to the common good.

• A family is connected through emotional ties, just as the state aims to create a sense of unity and shared identity.

Justice

Distributive and Retributive Justice:

• Distributive Justice: The just allocation of resources among the population of a society; John Rawls was a key theorist in this, as he explained the principles of justice as fairness. An example of distributive justice would be guaranteeing that everyone has access to basic healthcare and education.

• Retributive Justice: This type of justice focuses on punishment for any wrongdoing, which ensures that offenders are held accountable for their actions. An example of this would be implementing sentencing laws matching the extremity of the crime committed.

Social Justice: This type of justice aims to create a society where resources are distributed fairly, and all individuals are treated equally in a society, including protecting fundamental rights, and equality of opportunities. An example of this would be to create and enforce policies that address and attempt to solve systemic inequalities in a society.

Justice and Freedom: The relationship between the two is very close, as a society that implements justice often needs the protection of individual freedoms. There are two types of freedoms: positive and negative freedoms, with negative freedom being freedom from any interference, and positive freedom being freedom to achieve potential.

Justice and Equality: This is another relationship tied very close together, as justice is often linked with the goal of equality among all individuals, whether it be equal treatment under the law, or addressing historical inequalities. An example of this would be addressing the policy of affirmative action to address previous injustices that have occurred.

Interrelationships between Justice, Freedom, and Equality: These concepts are interdependent and a just society should aim to balance these concepts, such as implementing policies that provide equal opportunities to all, while respecting individual freedoms.

Distinction between Distributive and Retributive Justice: While distributive justice concerns the fair allocation of opportunities and resources in a society, retributive justice is concerned with the punishment of crimes and ensuring offenders receive their just punishment.

Right/Will of the Strong: This concept is the idea that those with power and strength should use their will and define justice. This idea can be traced back to Plato’s “Republic”, and it often challenges the concept of universal justice.

Substantive vs. Procedural Justice: Substantive justice refers to the content of laws and policies, and the ensurance that they are fair and equitable, focusing on the fairness of the laws themselves. Procedural justice, on the other hand, refers to the processes through which legislation is implemented, focusing on the fairness of the process of law-making.

Truth, Moral Law, and Positive Law

Truth: Philosophically, this concerns truth and its relationship to justice, as the pursuit of truth is needed in some legal contexts and ethical debates.

Moral Law: This refers to the ethical values that guide human behavior, which are usually universal. They can be religious, philosophical, or just human rights. Some examples are the concept of human rights, prohibiting murder, etc.

Positive Law: This refers to laws that are enforced by governments, and they can vary between societies, and can also be altered through legal processes. Some examples of this would be criminal codes, civil laws, etc.

Gender Politics: Key Concepts

Gender vs. Sex: Gender refers to the social and psychological attributes that societies assign to individuals based on their sex, while sex refers to the biological differences between the male and female bodies.

Feminism: A movement that advocates for women’s rights and gender equality.

Intersectionality: A concept that highlights the different aspects of identity intersect and create unique experiences of oppression and privilege.

Patriarchy: A social system in which men hold primary power and dominate in roles of political leadership, moral authority, social privilege.

Relations to Fairness: Fairness is a major concept in political philosophy, often intertwining with justice, rights, and societal structures. Distributive justice sees fairness as the equal distribution of resources, based on individual needs and contributions. An example of this would be social welfare programs. Procedural justice and fairness will intertwine in ensuring that decision making processes are fair and transparent, such as creating legal systems that guarantee fair trails.

Why did Hayek describe social justice as an “empty phrase without determinable content”?

Hayek believed that the term “social justice” did not have a clear and universally accepted definition. Different groups often have conflicting definitions about the meaning of social justice, and according to Hayek, the term then often turns into a phrase that can be manipulated to serve political agendas.

What role does equality play in theories of justice?

The way equality is used as a concept in achieving justice varies across different philosophies. The following summarize how equality is integrated into key theories of justice.

• John Rawls Theory of Justice: Each person has an equal right to basic liberties, and this prioritizes fundamental freedoms and equality. Social and economic inequalities are only allowed if they result in benefits for everyone.

• John Stuart Mill and Utilitarianism: The Principle of Utility states that the actions are right if they promote the greatest overall happiness for the greatest population, but it does not prioritize equality.

• Libertarianism: Justice is about the fair transfer of holdings, and as long as the process is fair, the resulting distribution is unequal. Libertarianism emphasizes equality in terms of individual freedoms.

• Marxism: This form advocates for the abolition of class distinctions and establishing a classless society where things are distributed according to need.

Is Strict Equality Impossible?

• Arguments against the possibility of strict equality: There are individual differences when thinking of human diversity, and economically, to have a perfectly equal distribution of resources is virtually impossible due to the sheer complexity of measuring everyone’s needs equally.

• Arguments in favor of striving for greater equality: Many argue that equality is needed to respect human dignity and ensure the individuals are treated with equal respect. Additionally, greater equality can lead to better social stability, decreasing social unrest. Economically, redistributing wealth from the rich to the poor can increase overall happiness.

Rights

Human and Non-Human Rights

• Human Rights: The moral values defining the certain levels of human behavior and are just as protected as legal rights are in international law.

• Non Human Rights: The rights given to the entities other than human beings, including animals, ecosystems, and artificial intelligence.

Natural and Legal Rights

• Natural Rights: Those rights that individuals have automatically, just by being human. These rights are considered universal and not dependent on any laws or customs of any society/governing body.

• Legal Rights: The rights that are granted and then protected by a particular society or government; these rights are specific to the legal system. These rights are backed by the power of the state and the legal institutions it comprises of.

Rights, Duties, and Responsibilities:

• Rights: Entitlements of a moral viewpoint than an individual or group may have.

  • Types of Rights: Natural rights, Legal rights, Human rights

  • Key Theorists: John Locke (advocated for natural rights), Immanuel Kent (insisted on the worth of individuals and their rights to be treated well), John Stuart Mill (rights are justified by their use in promoting overall happiness)

Are human rights inalienable and universal?

Inalienable rights are those that cannot be taken away, regardless of the circumstances. The arguments for the inalienability of human rights are based heavily on moral and ethical bases. The arguments against it include practicality. In reality, human rights can be violated by governments, which challenges the notion of their inalienability. Additionally, the concept of inalienable rights is a Western concept that may not be applied in all cultural societies.

Do non-human animals have rights? Do non-living things have rights?

• The debate surrounding animal rights revolves around the key theories of utilitarianism, deontology, and ethics. The utilitarian approach states that the capacity to suffer should be the basis for rights, and since animals can suffer, they should be given moral consideration. The deontology approach argues that animals have intrinsic values, and deserve rights based on this.

• The debate surrounding the rights of non-living things argues for the intrinsic value of all ecosystems, and supports moral consideration for non-living elements of nature.

Legal rights, and their relationship with moral rights

• Legal Rights: By definition, these are rights that individuals will have within a specific jurisdiction, protected by a legal system. These rights are protected and enforced by the government.

• Moral Rights: These are rights that individuals have through ethical or moral values, and they are considered to be universal, regardless of legal jurisdiction and recognition.

• The relationship between moral and legal rights

  • Alignment and intersection of the two rights: in many cases, legal rights are often heavily based on moral rights. Sometimes, there are laws in certain counties that may violate universal human rights (moral rights)

  • Foundation of rights: legal rights get their legitimacy through moral rights, and moral rights can be turned into legal rights through declarations, legislations, and constitutions.

Conflict of Rights, Denial of Rights:

Conflict of Rights:

• This occurs when two or more rights come into opposition with one another; sometimes, upholding one right might lead to infringing another right.

• For example, the freedom of speech vs. the right to privacy: If a person uses their freedom of speech by sharing someone else’s private information, it’s a violation of the other person’s right to privacy.

Denial of Rights:

• This refers to situations where an individual or group is deprived of their rights in a systematic way.

• Examples of this include: Discrimination, in which the denial of rights is based off religion, race, or other defining characteristics.

Analyzing the Conflict and Denial of Rights:

• Identify which rights are involved

• Evaluate and assess the ethical principles, using ethical perspectives and theories to analyze the situation.

• Propose a solution

• Reflect on the implications of the resolutions.

Universal Declaration of Human Rights

• This is a document compiled by multiple representatives, all with different legal and ethnic backgrounds. It is seen as a “common standard of achievement for all peoples and all nations”. Every human globally is entitled to the rights and freedoms set forth in the declaration, without any distinction between race, color, sex, language, ethnicity, etc.

Key Themes: Human Rights & Ethics, Justice and Political Philosophy, Moral Relativism

Declaration of Human Duties and Responsibilities

• This was written in 1998 to strengthen the implementation of human rights, created by UNESCO and the UN High Commissioner of Human Rights. It was created to reinforce the implementation of human rights, and to ensure that human rights were upholded by all governing bodies.

Unit 9: Exploring Philosophical Activity

Introduction to Philosophical Activity

• Definition and Scope: Philosophical activity encompasses the systematic practice of examining and evaluating fundamental questions and concepts related to existence, knowledge, values, and reason. It involves a deliberate process of inquiry aimed at uncovering truths, understanding underlying principles, and resolving conceptual issues.

• Purpose: The primary goal is to deepen our understanding of complex issues and to challenge existing beliefs. Philosophical activity helps in shaping our worldview and influencing various domains of human life, including science, politics, ethics, and personal decision-making.

• Nature: It is characterized by an openness to questioning established norms, a commitment to rigorous analysis, and a readiness to engage in critical reflection. This ongoing process drives the evolution of philosophical thought and its practical implications.

Key Philosophical Activities

• Questioning:

  • Metaphysical Questions: These address the fundamental nature of reality and existence. For example:

    • Ontology: What entities exist? Are there different kinds of being (e.g., physical, abstract)?

    • Identity and Change: What does it mean for something to be the same thing at different times?

    • Causation: What is the nature of cause and effect?

  • Epistemological Questions: These concern the nature and scope of knowledge. For example:

    • Sources of Knowledge: How do we acquire knowledge? Is it through sensory experience, reason, or intuition?

    • Justification: What makes beliefs justified or rational? How can we distinguish between true knowledge and mere belief?

    • Skepticism: Can we know anything with certainty? What are the limits of human knowledge?

  • Ethical Questions: These focus on moral values and conduct. For example:

    • Moral Principles: What are the fundamental principles of right and wrong? Are they objective or subjective?

    • Ethical Theories: How do different theories (e.g., utilitarianism, deontology) approach moral dilemmas?

    • Virtue Ethics: What constitutes a good character? How should we cultivate virtues?

  • Aesthetic Questions: These explore the nature of beauty and art. For example:

  • Key Contributions:

    • Socrates: Developed the Socratic method, a form of cooperative dialogue aimed at stimulating critical thinking and uncovering underlying assumptions. His focus was on ethical inquiry, encouraging individuals to question their moral beliefs and understand the nature of virtue.

    • Plato: Introduced the Theory of Forms, which posits that non-material abstract forms (e.g., beauty, justice) represent the most accurate reality. He also explored political philosophy, particularly in works like "The Republic," where he discusses the nature of justice and the ideal state.

    • Aristotle: Made significant contributions to logic with his development of syllogistic reasoning. His work in metaphysics includes examining the nature of existence and causality. In ethics, he is known for his concept of virtue ethics, emphasizing the development of good character traits.

• Medieval Philosophy:

  • Focus: Integration of philosophical reasoning with religious thought, influenced by Christian, Jewish, and Islamic traditions.

  • Figures: Augustine of Hippo and Thomas Aquinas.

  • Key Contributions:

    • Augustine of Hippo: Provided influential theological insights, including the concept of original sin, which explores the human condition and the nature of evil. His writings helped shape Christian doctrine and Western thought on issues of faith and reason.

    • Thomas Aquinas: Known for his scholastic synthesis of Aristotelian philosophy with Christian theology, particularly in his work "Summa Theologica." He integrated reason and faith, arguing that both can lead to truth, and provided a comprehensive account of Christian doctrine.

• Modern Philosophy:

  • Focus: Rationalism, empiricism, and the Enlightenment.

  • Figures: René Descartes, Immanuel Kant, and Georg Wilhelm Friedrich Hegel.
