Ethics Introduction
1. Why Study Ethics? • Human beings are moral beings. • We make ethical decisions everyday. • Ethical decisions determine one’s identity. • Free will
2. What is Ethics? • Moral Philosophy • Examines right and wrong actions. • Prescribes how one ought to behave.
Three parts to Ethics • 1) Meta-Ethics • 2) Normative Ethics • 3) Applied Ethics
Metaethics • Meta-ethics is concerned with whether there is a right or wrong. • Relativism, skepticism, pluralism and realism. • Concerned with the meaning of right and wrong and good and bad.
Normative Ethics • Determining what is right and wrong and why it is right or wrong. • Theoretical Ethics: the construction of ethical theories that help determine what is right and wrong (e.g., utilitarianism, naturalism, Kant’s deontology, etc.)
Applied Ethics • Applied Ethics: the application of ethical theories to concrete issues, such as euthanasia, abortion, etc.
3. Ethics and religion • Religion: Divine Command Bible/ Koran/ etc. • Religion also prescribes action (i.e., tells us how one ought to behave), but the support for these claims is divine revelation • Ethics: is based solely on experience and reason
4. Ethics and Other Evaluations Prescriptive Descriptive • Legal • Aesthetics • Religion • Law • Custom • Ethics • History • Anthropology • Sociology • Psychology
Ethical Terms • Ethically Right Acts • Ethically Wrong Acts • Ethically permissible Acts • Morally good person • Morally bad person • Ought/Duty • Rights • Just/unjust/fairness
5. Reason and Emotions • One Position: Emotions ought to be separated from ethical evaluations • Second Position: Emotions should not be detached from ethical evaluations. • Third Position: Some emotions to a certain degree ought to be detached from ethical reasoning.
6. Ethical Reasoning and Arguments • A Claim • A Belief • A subjective claim • An objective claim • Evidence and justification • Basic claims/first principles
Claim • A claim has a truth value, meaning that it is either true or false. • Subjective claims are about one’s emotions or feelings or sensations. They are ONLY about oneself. • Objective claims are about the world and not about one’s feelings. • We are interested in objective claims.
Claims Objective Subjective • 1) It is 78 degrees Fahrenheit in the room. • 2) The soup has 2 grams of salt. • 3) What you did was ethically wrong. • 1) it is warm in the room. • 2) The soup taste salty. • 3) What you did embarrassed me.
Arguments • An argument is a set of claims in which some are premises and one is a conclusion, and the premises support the truth of the conclusion.
Evaluating and Constructing Arguments • The conclusion should be the controversial claim. • The premise(s) should be the claim(s) that are most commonly accepted. • Step1: The premises should support the truth of the conclusion. • Step 2: The premises should be true.
Step 1: Determine if the argument is valid or invalid. • A valid argument is one in which, if the premises are true, the conclusion follows necessarily. • All x’s are y’s, and all z’s are x’s. Therefore, it follows necessary that all z’s are y’s.
Invalid • An invalid argument is one in which, if the premises are true, the conclusion follows with some probability and not necessarily. • If the probability is greater than 50% then we call it an invalid strong argument. • Invalid strong arguments are good arguments.
Step 2: Check to determine if the premises are true • All arguments, whether valid or invalid, must have true premises. • If just one of the premises is FALSE, then the argument fails. • A valid argument with all true premises is a SOUND argument. (BEST!) • An invalid strong argument with all true premises is a COGENT argument. (GOOD!)
Two ways to refute an Argument • 1) Show that the premises do not support the conclusion, and therefore, the argument is neither sound or strong. We call these arguments Invalid WEAK arguments. • 2) Show that one or more of the premises is false or probably false.
Evaluating Ethical Arguments • Facts • Concepts • Values
