Comprehensive Study Guide: Philosophy, Ethics, and Religion

The Nature of Philosophy and Truth Claims

• Etymology: The word 'philosophy' literally means 'the love of wisdom', derived from the Greek words philos (love) and sophos (wisdom). Wisdom is defined as the human desire to understand the world as it actually is to live a more fulfilled life.

• Socratic Purpose: Socrates stated the purpose of philosophy is to question everything, famously asserting, 'The unexamined life is not worth living.'

• Truth Claims: Philosophers investigate truth claims—statements asserted as true—to understand why they are true (or false) and the methods used to establish that truth. Identifying the type of truth claim prevents confusion between different domains of knowledge.

• Examples of Truth Claims:     * Political: 'London is the capital of the United Kingdom.'     * Theological: 'God is all-powerful.'     * Historical: 'The First World War was caused by the assassination of Archduke Franz Ferdinand.'     * Biological: 'Humans are mammals.'     * Mathematical: $7 + 5 = 12$.

• Disputing Claims: Truth claims are often disputed. For instance, a Scottish nationalist might only recognize London as the capital of England, while historians may debate whether an assassination was a direct or probable cause of war.

• The Role of Philosophy: Philosophy aims to clarify problems, identify false assumptions in beliefs, and point out when an argument uses the wrong method of reasoning.

Philosophical Methods: Validity and Soundness

• Definition of Argument: A series of connected statements (premises) ending with a conclusion (proposition).

• Validity: An argument is valid if each statement is logically connected to the conclusion. A valid conclusion contains only the truth claims of the previous statements and should never add new ideas.

• Soundness: An argument is sound if it is both valid and the statements within it are actually true.

• The Harry Potter Example (Valid but Unsound):     * Premise $1$: Everyone who reads a Harry Potter book is a genius.     * Premise $2$: Mary is reading a Harry Potter book.     * Conclusion: So, Mary is a genius.     * Analysis: This is logically valid, but unsound because the first premise is false.

• The Blue Tie Example (Valid and Sound):     * Premise $1$: All pupils at this school wear blue ties.     * Premise $2$: Harry is a pupil at this school.     * Conclusion: So, Harry wears a blue tie.     * Analysis: Valid and sound (assuming the premises are factually true).

Tools for Analyzing Arguments

• False Statements: Arguments based on incorrect facts (e.g., 'whales are fish') are faulty and unsound.

• Ambiguity and Definitions: Words with multiple meanings weaken arguments. Example: 'Police help dog bite victim' can mean the police assisted a victim or encouraged a dog to bite. Definitions that are too broad (e.g., 'wrongdoing is anything that causes pain') or too narrow (e.g., 'mankind' referring only to males) are problematic.

• Law of Non-Contradiction: A statement cannot be true and false at the same time. One cannot exist and not exist simultaneously.

• Analogies: Using a known thing to explain something new. A good analogy requires many similarities. Examples include Jesus' parables (The Good Samaritan) and Plato's Parable of the Cave. Weak analogies have few similarities or many irrelevancies (e.g., David Hume's critique of the design argument).

Major Areas of Philosophy and Western Thinkers

• Epistemology: 'What can I know and how do I know it is true?'

• Metaphysics: 'What is real and how does it exist?'

• Moral Philosophy (Ethics): 'What ought I to do?'

• Logic: 'What is a valid argument?'

• History of Philosophy: Important for understanding when ideas developed and their contextual influences.

• List of Notable Philosophers:     

• Protagoras ($c.\,490-c.\,420\,BC$)     

• Plato ($428/427-348/347\,BC$)     

• Aristotle ($384-322\,BC$)     

• Cicero ($106-43\,BC$)     

• Augustine ($354-430$)     

• Anselm ($c.\,1033-1109$)     

• Aquinas ($1225-1274$)     

• Erasmus ($1466-1536$)     

• Descartes ($1596-1650$)     

• Locke ($1632-1704$)    

• Leibniz ($1646-1716$)     

• Hume ($1711-1776$)     

• Kant ($1724-1804$)     

• Hegel ($1770-1831$)     

• Mill ($1806-1873$)     

• Wittgenstein ($1889-1951$)     

• Sartre ($1905-1980$)     

• King ($1929-1968$)

The Argument from Design (Teleological Argument)

• William Paley ($1743-1805$): Paley used an inductive argument based on the 'design' of natural phenomena.

• The Watch Analogy: If one finds a watch in a field, the complexity of its mechanism suggests a watchmaker. Similarly, the complexity of the universe (e.g., the human eye, bird wings, fish gills) suggests a 'Divine Designer' or Creator God.

• Evidence for Design:     * Laws of Science: Gravity, magnetism, and motion involve complex things working according to a plan.     * DNA: The double helix structure and replication process indicate a 'blueprint' for life.     * Evolution: Some view the development of complex life from simple forms as evidence of a plan.     * Beauty of Nature: The aesthetics of sunsets and oceans suggest artistic intent.

• Criticisms of Design:     * Evidence of 'lack of design' like volcanoes, disease, and earthquakes.     * Science (evolution/physics) can explain complexity without God.     * Dinosaurs seem unnecessary to a design plan for the current world.     * The argument suggests a designer, but not necessarily the Christian God—it could be multiple gods or an evil designer.

The Cosmological Argument and Causation

• St. Thomas Aquinas: Argued that the universe ($cosmos$) is evidence for God. Nothing comes from nothing; every effect has a cause.

• The First Cause: There must be an 'Unmoved Mover' or 'First Cause' that began the chain of cause and effect without being caused itself.

• Train Analogy: A line of railway wagons moves because each is pulled by the one before it, but the whole process requires an engine (the First Cause).

• Counter-Arguments:     * If everything needs a cause, what caused God?     * The universe/matter could be eternal (The 'Steady State' theory or Karl Marx's view that matter is infinite and self-reproducing).

Moral and Religious Experience Arguments

• Argument from Morality: Humans are born with a sense of right and wrong (conscience), which some argue must be given by God. Selfless figures (Mother Teresa, Gandhi) illustrate the power of these convictions.

• Religious Experience: Includes visions, voices, dreams, and feelings of 'awe.' St. Paul's conversion on the road to Damascus ($c.\,50\,AD$) is a key example.

• The Problem of Subjectivity: Religious experiences are subjective and cannot be independently verified, unlike objective evidence. Non-believers might attribute these to imagination or psychological states.

Humanism and Moral Frameworks

• Definition: A non-religious worldview focusing on reason, ethics, and human welfare. Humanists believe this is the only life we have and trust the scientific method over the supernatural.

• Statistics: A $2013$ British Social Attitudes survey found $51\,\%$ of the population (and $69\,\%$ of young people aged $18-24$) are non-religious.

• Ethics Models:     * Moral Absolutism: Set rules that apply to everyone.     * Moral Relativism: Ethics depend on situation and consequences.     * Moral Objectivism: Good/bad rules exist for everyone but allow for exceptions (the lesser of two evils).

Ethical Issue: Abortion

• Definition: The removal of a foetus from the womb before it can survive.

• United Kingdom Law:     * 1967 Act: Requires two doctors to agree that there is risk to the life, physical/mental health of the mother or existing children, or substantial risk of handicap.     * 1990 Act: Set a limit of $24$ weeks, except in cases of grave risk to the mother or severe abnormality.

• Statistics: Abortions in England and Wales rose from $86,565$ in $1970$ to $189,931$ in $2011$; in $2011$, $79\,\%$ were carried out under $10$ weeks gestation.

• Religious Perspectives:     * Catholic and Evangelical Protestant: Often opposed. Based on 'Sanctity of Life' (Jeremiah $1:5$: 'Before I formed you in the womb I knew you'). Life begins at conception; adoption is seen as the better solution.     * Doctrine of Double Effect: Allows for procedures where the death of the foetus is an unintended side effect of saving the mother (e.g., chemotherapy for cancer).     * Liberal Protestant: May permit abortion as the 'most loving' thing (agape) in cases of rape, extreme poverty, or severe handicap.

• Humanist View: Focuses on the 'Quality of Life' and personal choice. A foetus is not considered a 'person' with rights until well after conception. Priorities are placed on the woman's happiness.

Ethics of War and Pacifism

• War Realism: War is an inevitable fact of life to oppose evil leaders.

• War Militarism: War can bring a nation together and express national values (e.g., Holy Wars).

• Just War Theory: War is the 'lesser of two evils.' Criteria include:     * Jus ad bellum (Justification): Just cause, authorized by government, good intention, chance of success, last resort, proportionality.     * Jus in bello (Justice in war): Proportionate force, protection of non-combatants.     * Jus post bellum (Justice after war): Restoring law and order, environmental protection.

• Pacifism:     * Absolute Pacifists: All war is wrong (sanctity of life). Examples: Martin Luther King and Jesus' teaching to 'turn the other cheek.'     * Weak Pacifists: Use war only as a last resort based on utilitarian principles (greatest happiness for the greatest number).

Capital Punishment and Aims of Punishment

• History: The Waltham Black Act ($1723$) listed over $50$ capital offenses. Capital punishment was abolished in the UK in $1965$ ($confirmed\,1969$). It remains in countries like China, Iran, Saudi Arabia, and parts of the USA.

• Aims of Punishment:     * Retribution: Paying back the offender (lex talionis - 'an eye for an eye').     * Deterrence: Discouraging others from committing the crime.     * Protection: Keeping society safe from the offender.     * Reform: Rehabilitating the offender to rejoin society.

• Pope Francis: Called for global abolition ($2016$), stating 'You shall not kill' applies to both the innocent and the guilty. He denounced life imprisonment as a 'hidden death penalty.'

• Arguments For: Retribution for life-takers; deterrence; certainty that the person will not kill again; lower cost than life imprisonment.

• Arguments Against: Risk of executing innocent people ($350$ cases in USA since $1900$, $23$ executed); violation of the right to life; failure as a deterrent; discriminatory use against the poor or minorities.

The Problem of Evil and Suffering

• Types of Evil:     * Moral Evil: Caused by human free will (e.g., murder, war, burglary).     * Natural Evil: Not caused by humans (e.g., tsunamis, earthquakes, cancer).

• The Inconsistent Triad: How can God be Omni-benevolent (all-good) and Omnipotent (all-powerful) if Evil exists? If he is all-powerful, he can stop it; if all-good, he wants to stop it.

• Theodicies (Explanations):     * Original Sin: The fall of Adam and Eve introduced a tendency toward evil.     * St. Augustine: Evil is an 'absence of good,' like a disease is an absence of health.     * Satan: Evil is the work of a personified devil.     * Soul-Making: Life is a preparation for paradise; suffering helps people improve their souls.

• Diversity of Responses:     * Buddhist: Suffering is caused by craving and ignorance. Follow the Eightfold Path (Right Vision, Emotion, Speech, Action, Livelihood, Effort, Mindfulness, Meditation).     * Jewish: Suffering results from misuse of free will (Genesis $3$). The Book of Job teaches that humans cannot fully understand divine purpose, but faith remains essential. Jews have faced historical suffering through Anti-Semitism (pogroms, Holocaust), yet maintain hope in a future Messiah.

Prejudice, Discrimination, and Human Rights

• Definitions: Prejudice is a biased belief based on stereotypes. Discrimination is the unfair treatment resulting from that prejudice.

• The Stephen Lawrence Case ($1993$): A racist murder in London that highlighted 'Institutionalized Racism' in the police force, leading to the Macpherson Report ($1999$).

• John Stuart Mill ($On\,Liberty$):     * Liberty Principle: Individuals should be sovereign over their own bodies and minds.     * Harm Principle: The only reason to exercise power over someone against their will is to prevent harm to others.

• Universal Declaration of Human Rights ($1948$): Created by the UN after WWII ($15.6\,million$ soldiers and $39.2\,million$ civilians died).     * Article 1: Humans are born free and equal.     * Article 19: Right to freedom of opinion and expression.

• Christianity and Human Rights: Humans are made in the 'Image of God' (Imago Dei), giving them intrinsic value. Acts of kindness to the marginalized are seen as acts toward Christ.

Environmental Ethics and Animals

• Environmental Crisis: Issues include global warming ($CO_2$ greenhouse effect), deforestation, toxic waste, and resource depletion (oil may be depleted by $2050$).

• Ecological Positions:     * Shallow Ecology: Human-centered. We protect the environment so we don't suffer.     * Deep Ecology: Humans and nature are deeply connected. The 'Gaia' hypothesis views the planet as a single living organism.

• Stewardship: The Christian belief that humans are guardians, not owners, of the Earth (Genesis $2:15$: 'cultivate and guard it').

• Animal Rights:     * René Descartes: Thought animals were machines without souls/consciousness.     * Jeremy Bentham: 'The question is not, Can they reason?… but, Can they suffer?'     * Religious Views: Catholics focus on human duties to be kind to animals; Quakers have a high proportion of vegetarians and strongly oppose hunting and vivisection.

• Vegetarianism: $8,000,000,000$ animals are killed annually in the US food industry ($16,000$ per minute). Arguments center on whether the pleasure of eating meat justifies the suffering of intensive farming.

• Conservation: Practical efforts include the Kyoto Summit ($1997$), Paris Climate Agreement ($2016$), and 'thinking green' via recycling and emission-free zones (e.g., Oxford $2020$).

Questions & Discussion

• Question: What is a persuasive argument?     * Philosophical Response: It must be valid (logical structure) and sound (factual premises).

• Question: 'Philosophy is the most important subject there is to study.' Do you agree?     * Considerations: It teaches critical thinking and ethics, but others argue science provides the practical solutions for human survival.

• Question: Do you think you have a conscience?     * Reflection: Is it a 'voice in the head' or learned social behavior?

• Question: 'War is never right. There are always better ways of resolving conflict.'     * Perspectives: Absolute pacifists agree; militarists argue some values are worth fighting for; Just War theorists argue it is a necessary last resort.

• Question: Does the universe need a First Cause?     * Dialogue: If God is the cause, who caused God? Or is matter itself eternal?
