Phil 1200 Midterm: RJ Leland (Revised)

Arguments in philosophy

A sequence of statements, intended to support one or more conclusions
The truth of the premises gives you a reason to believe the conclusion

Premises

Statements that are simply asserted without proof in the context of the present argument.

Conclusion

The side of the argument leads to the main point and is supported by premises.

Validity

An argument can only be valid If Its premises entails to a conclusion. It's impossible for the conclusion to be false.

Example of a Valid argument

If it is raining, then the streets are wet. It's raining. Therefore, the streets are wet.

By logic, raining makes the street wet.

Invalidity

An argument can only be Invalid If Its premises does not entail to the conclusion, thus, making the conclusion false.

Example of a Invalid argument

If it is raining, then the streets are wet. The streets are wet. Therefore, It's raining.

It could be a construction. A movie play about flooding. It doens't have to be rain for the streets to be wet.

Soudness

The premises are true and the conclusion is true therefore, must be valid.

The argument is valid and their premises are true.

Sound Argument Examples

All rabbits are mammals. Bugs Bunny is a rabbit. Therefore, Bugs Bunny is a mammal.

Unsoundness

An argument is unsound when the argument is invalid, or if at least one of the premises is false.

Example of Unsound argument

All pigs can fly. Pinky is a pig. Therefore Pinky can fly.

Pigs can't fly by logic, so It makes Premise 1: False. The argument is still valid, however.

Formal Validity

When an argument is an instance of a scheme all of whose instances are valid, the argument is said to be formally valid.

Modus Tollens

If p, then q
Not q
Therefore not p

Modus Ponens

If p then q
p
Therefore q

Disjunctive Syllogism

Either p or q
It is not the case that p
Therefore q

Hypothetical Syllogism

If p then q
If q then r
If p then r

Contraposition

If p then q
If it is not the case that q, then it is not the case that p

What is the Sorites Paradox?

This reasoning leads to the absurd conclusion that no number of objects is something indistinguishable from the other.

What makes a good argument?

Acceptability: Is your argument logical and a reasonable one?

Relevance: Are your arguments relevant?

Sufficiency: Is there sufficient evidence?

It is important for someone to accept the premises first before the conclusion. If the conclusion is doubted, then the premises did nothing to support the conclusion.

Demonstrative Arguments

Arguments that aim to be valid.

It entails Its conclusion

Generate an argument where It leads an entailment to the conclusion from its premises.

Includes proof. The conclusion is supported and entailed

Non demonstrative Arguments

Premises entail somewhat of the conclusion. Premises can doubt the conclusion but may still be valid.

Inductive Argument

Started with a particular observation to a generalized claim. Tactically relies on the idea that the particulars are a guide to the general. Typically, Hypothetical.

Inference to Best Explanation

The offered premise is the best available, then we are justified in believing the conclusion.

Euthyphro

Socrates and Euthyphro are both on trial, Euthyphro prosecuting his father who killed an employee for having killed an enslaved person, and Euthyphro is confident hes acting piously/righteously, so Socrates is asking him what piety/righteousness is to him.

Euthyphro's Dilenma

If something is loved by the gods because it is pious, or pious because It’s loved by the gods.

Divine Command Theory

Morally required/forbidden actions are required because of god's commands, permissible actions are those where god neither commands nor forbids.

Cultural Relativism

The practice of judging a culture by its own standards. Proposes that what is ethical is relative to, or depends on cultural attitude.

Theory of Right Action

Explains why things are wrong/permissible/required that leads to ethical values.

Consequentialism

Rightness/wrongness of an action is determined only by its effects on the world. Try to avoid the worst case scenario.

Utilitarianism

The principle of Utility: Ought to do what action best maximizes happiness and minimizes unhappiness.

Principle of Asceticism

a practice where one gets rid of worldly pleasures and focuses on thinking, particularly for religious or spiritual purposes (e.g. Buddhist Monk)

Measures of pleasure and pain (Utilitarianism)

Its intensity, duration, certainty or uncertainty, its nearness and remoteness, fecundity (its chance of being followed by sensations of the same kind) purity (its chance of not being followed by opposite sensations), and its extent (the number of persons to whom it extends or whos affected by it)

the rights objection (utilitarianism)

charges utilitarianism with being overly permissive. To
maximise the sum total of well-being, utilitarianism might be thought to allow
infringing upon others’ rights or violating other apparent moral constraints.

The demandingness objection (utilitarianism)

claims that utilitarianism is overly demanding
because it requires excessive self-sacrifice from us in order to help others.

The equality objection (utilitarianism)

holds that utilitarianism is not sufficiently concerned
with distributive justice and the value of equality.

The mere means objection (utilitarianism)

claims that utilitarianism treats people as “mere
means” to the greater good rather than as ends in themselves

The separateness of persons' objection (utilitarianism)

charges utilitarianism with
aggregating well-being in an unacceptable way, neglecting the significance of
the boundaries between individuals.

The alienation objection (utilitarianism)

alleges that the moral reasons posited by
utilitarianism are troublingly cold and aloof, alienating us from the particular
people and projects that (rightly) matter to us

The special obligations objection (utilitarianism)

holds that utilitarianism is excessively
impartial, and does not sufficiently account for the special obligations that we
have to our friends and family.

Singer

Overemphasizes food insecurity and population size. Poverty in general.

Principle of Assistance

If It's in our power to prevent something seriously from bad happening without hereby sacrificing anything of moral importance, we ought to do it.

Susan Wolf

She believes there are 2 types of moral saints; the loving saint, and the rational saint. Both have lives organized around satisfying the demands of mortality, though they relate differently to those demands.

Rational Saint

Wants what we want but gives it up of our commitment to morality. They are not enjoying doing so, just for the sake of obligation.

Loving Saint

Being exceptionally morally good is what makes him happy. Enjoys and dedicate their life to kindness.

Deontology

An ethical theory that says actions are good or bad according to a clear set of rules. Actions that align with these rules are ethical, while actions that don't, arent.

Prima Facie Duty

Justice

Fairness and distribution, duty to contribute to forming and maintaing fair distribution, about distributing things according to merit so that good persons get more and bad persons get less.

Beneficence

In position to help people, confer on them a benefit or protection from harm. Singer's views.

Self improvement

Make yourself a better person over time

Non-maleficence

A duty not to harm
