Logic
the systematic study of arguments in order to determine whether they are good or bad. The means by which we figure out the truth.
Logical analysis steps
Identification
Assessment
Argument
a series of claims organized in an effort to defend a position on an issue.
Argument requirements
one premise, one conclusion, not necessarily multiple parties
Premise
claim that supports a position on an issue, indicated by “because” or “since”
Conclusion
a claim supported by premise(s) that states position, indicated by “thus” or “as a result”
Identification (deductive)
Deductive. A conclusion is thought to necessarily follow given the form of the argument itself. The premises prove or demonstrate the conclusion.
Assessment (deductive)
validity
soundness
Validity
A deductive argument is valid if it is not possible for the conclusion to be false assuming the premise(s) are true, even if they aren’t.
Soundness
A deductive argument is sound if it is valid AND all premises are true.
Identification (Inductive)
A conclusion is thought to be supported, but not proved, by the premise(s). The premises make the conclusion more likely, but not certain.
Assessment (inductive)
strength
cogency
Strength
an argument is strong if the premise(s), when assumed to be true, make the conclusion significantly more likely.
Cogency
an inductive argument is cogent if it is strong AND all premises are true.
Argument by analogy
An inductive argument that suggests that because two things are similar in one respect, they must be similar in all/or most others.
Fallacies
mistakes in reasoning, which can indicate a bad argument. (not all fallacies are related to arguments)
Ad Hominen
a personal attack rather than an argument against a position
Straw man
Intentionally exaggerating a person’s belief so it is easier to refute.
False dilema
Options are reduced to two (or less than the real number) possibilities, when, in reality, other options are there.
Ancient Era: Areas of Study
No particular areas of focus
Ancient Era: Figures
Pre-Socrates (ex: Pythagorus), Paramendies, Herclitus, the Buddha, Socrates, Plato, Aristotle, and Thalies (Father of Philosophy).
Medieval Era Areas of Focus
primarily christianity and religion focused. What is God? What proof is there? What is God’s essence?
Modern Era Areas of Focus
more objective, less (but still, arguably) religious. Metaphysics and epistemology.
Epistemology
What do we know and how? What makes something concrete enough to “know”?
Metaphysics
What exists? What is real? Does the “mind” exist?
Modern Era Prominent Figures
René Descartes, David Hume, Immanuel Kant, John Stuart Mill, Fredrich Nietzchice.
Contemporary Era Areas of Focused
Analytic and continental
Analytic
WE are the issues that we create. Fix language and thinking/logic and you fix your problems. Primarily western.
Continental
philosophical problems will hapen no matter what. Why do they happen? (existentialism) Primarily non-western.
Contemporary Era Prominent Figures
Jean-Paul Sarte, Bertrand Russell, Ludwig Wittgenstein, Martin Heiddegger, Albert Camus, and Jaques Derrida
Ethics
What is evil? What is the nature of morality? Where does morality come from—God, constructs, etc.? Right actions vs. wrong.
Morality vs. Science
Prescriptive vs. descriptive statements. Morality: How should it be? Science: How is it currently?
Normative Ethics
Ethical theory + applied ethics
Ethical Theory
What should we do theoretically? General principles dictate what we should or should not do. Ex: utilitarianism and deontology.
Applied Ethics
What should we do in practice? Specific practical solutions. Ex: business or medical ethics
Meta-ethics
What is the nature of moral claims? More naturalistic account of ethics, describes how things are in the realm of moral philosophy and judgement.
What do we mean by moral claim? What is the nature of such a claim? How, if possible, can we defend it? What is indicative of morality?
Morality
concerns beliefs about right and wrong actions and good and bad people or character.
Moral norms
standards in the form of moral judgements, principles, rules, or theories.
Impartial
Apply to everyone equally. Equal moral worth and weight.
Overridingness
moral norms have a stronger hold than non-moral norms, and, therefore, can cause us to override them.
Universal
Apply in every situation that is relevantly similar to another. Morality demands consistency.
Reason-driven
moral judgements are supported by good reason.
Critical thinking
The corrective of feelings which are products of psychological needs, culture, and motivation.
Conscience
conditioned by upbringing, culture, etc. Can be the result of irrelevant influences and, therefore, not an infallible indicator of moral truth.
Norms of Obligation
obligatory conduct or duty, (generally) determine moral worth of actions
Norms of Value
estimations of moral worth, good or bad? Generally determine the moral worth of people, their character, and their motives
Right— Permissable
An action is allowed
Right— Obligatory
an action is wrong NOT to preform
Supererogatory
Not required, above and beyond
Melville’s view of Human Nature
Injustice is inherent to life
there is always undeniable evil in the world, that often triumphs over the innocent and good
Billy Budd
A "handsome sailor" who strikes and inadvertently kills his false accuser, Master-at-arms John Claggart. The ship's Captain, Edward Vere, recognizes Billy's lack of intent, but claims that the law of mutiny requires him to sentence Billy to be hanged. Represents a loss of innocence.
Morality vs. Legality
Is there an obligation to uphold the law even when, morally, it might be wrong? What constitutes changing the law?
The Brothers Karamazov: Ivan
The problem of evil
Traditional conception of God (omniscient, omnipotent, and just) + Existence of evil
Ivan’s conclusion
Either:
No God, or
God cannot be all-knowing, all-powerful, AND all-loving.
Attempts to Reconcile the Problem of Evil
Evil is necessary to appreciate good
Evil is an unfortunate consequence of God given free will
Human beings have limited intelligence and, thus, cannot understand what God does, and apparent evils might prove necessary in God’s plan.
Sophie’s Choice
“The tragedy of moral choice when all options are unacceptable”
Moral Responsibility in Sophie’s Choice
Does she become an active participant in the harm of one of her children by choosing one to live and one to die, even when she is not the one actually putting them in the harmful situation? Would she be MORE responsible for not choosing?
Negative Responsibility
Not making a choice is a choice in itself
Beliefs of Thomas Hobbes
fear dominates life
social contract
monarchy but no divine right of the kings (idea that monarchs are chosen by God and should not be held accountable to any earthly authority
psychological egoism
strong punishment
Psychological Egoism
self interest and gratification
The State of Nature
Anarchy, marked by fear
no security, industry, culture, navigation, imported commodities, buildings or large scale works, knowledge for its own sake, society, or civilization.
“solitary, poor, nasty, brutish, and short”
Essential Equality
everyone is equal in the State of Nature and has a right to self-preservation, everyone fears death
Right to Everything
freedom or liberty to do anything without consequences (without means)
Hobbes beliefs about security;freedom
ALL security, very little freedom is necessary
Natural Sources of Conflict
Competition: limited resources, motivated by gain
Diffidence: fear leads to preemptive aggression, motivated by security
Glory: wants recognition of power, motivated by reputation
Emergence of Civilization and Government
the state of nature is in the best interest of no one, self-interest leads to social contract. consents to sovereign which means forfeiting the right to everything.
Emergence of Ethics
No right or wrong in the state of nature. — force and fraud are good because they are essential for survival
Morality emerges after social contract
Moral Conventionalism
morality is indicative of free choice and social institutions and not innate.
Egoism
morality stems from need—self-interest
Everything “good” done benefits the one doing it. Morality=life preserver
Right
the freedom to do something
Law
a rule discovered by reason that one must follow in an effort to attain something
First law of nature
Right to everything, no security, fear of war is unwarranted.
Second law
give up right to everything
Third law
abide by social contract
The Caveat to the Laws of Nature
others must be willing to also forfeit rights
one is always allowed to do whatever needs to be done for self-preservation
Purposes of morality
enabling one to reach goals in socially acceptable ways
enabling fair conflict of interest resolutions
developing positive character
promoting happiness and flourishing/diminish suffering
enabling survival of society
assign praise and reward, blame and punishment
Pojman on Hobbes
Morality offers a form of social control, which reflects our rational and egoistic nature
Rules of morality: “if followed by nearly everyone, will promote the flourishing of nearly everyone.”
Pojman’s Claims
Morality is a necessary condition for happiness
the goal of morality is to create happy and virtuous people and flourishing communities
Lord of the Flies
painted faces symbolize return to savagery and freedom from conventional obligations— essentially equal.
Partly a response to The Coral Island
Hobbes’ sources of conflict are present
Empiricist
believes all knowledge is experience and sensation of external world
Rational
certain ideas, like mathematical truths, are inherent in human mind from inception. knowledge comes from reason
Political Influence
founding fathers’ government: sound laws, impartial judges, enforcing laws
State of Nature (John Locke)
equality
nothing stops anyone from doing whatever they want except natural empathy and rational capacity
a “state of nature” NOT a “state of license”
respect towards others
when survival is not at stake, people will try to protect mankind, not just themselves
Justification of Harm
right to enforce natural sense of justice
exercising of restraint, especially via punishment to prevent future harm
pursuit of reparations for past grievances or for damage done
Purpose of Government
Locke recognizes that there are issues with having individuals involved in violations administer punishment and justice
Governments help ensure fairness in the assessment of transgressions of natural law
Government Corruption
biases can still pervade governments, especially monarchies because governments are still administered by individuals.
with respect to a corrupt monarchy, “much better it is in the state of nature” (Locke)
Social Contract Theory
consent of the majority, majority rules
“every man puts himself under an obligation to submit to the determination of majority”
Reason for Social Contract
preserve property (to Locke—life, liberty, and material possessions
Why is the state of nature inadequate?
struggle to be impartial
no impartial judges
not always an ability to enforce natural law
Limits of Government
Consent of the governed must be continued
people can and should rebel is the government fails to attend to their interest, the reason for their initial consent
best safeguard against abuse of power is clearly stated rules and laws
Hobbes vs. Locke
Hobbes:
human beings have a constant disposition to fight
endow the sovereign with absolute power is necessary to ensure individuals will remain faithful to the contract
Locke:
optimistic view of human nature
natural sense of justice
one enters the social contract for their own interest
St. Thomas Aquinas and Natural Law Theory
Aristotle’s philosophy with a Christian theology
God is unnecessary to arrive at the NLT principles, rational means only (excluding creation)
Aristotle’s Influence
“the good life”
Eternal Law
the type of Divine Wisdom as directing all actions and movements
stems from God and reflects underlying order and purpose
all things naturally pursue what is good for them
everything partakes in eternal law
Natural Law
element of Eternal Law that humans can discern via reason that tells how to flourish
the way human beings come to know eternal law. how we become aware of good and evil
Divine Law
element of Eternal law that humans can discover by way of revelation (ex: holy texts) that tells how to flourish
Human law
A rule or regulation stipulated by the government or another authoritive power
The Good Life
natural inclination to things that are good, including:
preserving life
procreation
knowledge
sociability
Why is there evil?
Aquinas attributes this to ignorance and emotion—people who fail to do whats right either haven’t reflected enough or are over-powered by emotions
