3 Main Approaches to Ethics in Western Philosophy
- Deontology (reasons why I act)
- Duties and principles behind actions
- Divine Command Theroy
- Consequentialism (outcomes of act)
- Utilitarianism
- Ethical Egoism
- Virtue Ethics (who should I be)
Divine Command Theory
- Some way to unambiguously know the will of God
- Main reason why I act is because it's the will of God
Believe in a God that has rule over them
Usually from Judaism, Christianity or Islam
Problem with this thinking is that people do not know what God says 100% of the time.
Ethical Egoism
Do what is good for you, no matter what it does to someone else
Utilitarianism
Maximum benefit for the good of society
Bentham
- People governed by pain and pleasure
- Amount of pleasure can be calculated using the Hedonic Calculus
- 3 Requirements of Punishment
- Has to be intentional
- Has to take something away from you or harm you
- Has to be done because of something you did or everyone thinks you did
Mill
- Focused on quality of happiness
Descriptive Claims - claims about the way the world is
Prescriptive Claims claims about the way the world ought to be
Naturalistic Fallacy - confusing is's & ought's
Deterrence harming one individual to scare everyone else or teach everyone a lesson
Ideology refers to all the ideas we use to structure the world
*Utilitarianism can explain how people reach their everyday moral conclusions because it
is an wthical theory that focuses on harm and benefit or happiness and unhappiness to
morally significant beings.
*An action is morally bad if it harms someone, whereas it is morally good if it helps or
benefits someone.
*Ethical theories that claim that good and evil are related to consequences or results are
called consequentialist theories… Utilitarianism is a consequencialist ethical theory that
provides a means to evaluate actions.
*Betham and Mill thought that pleasure was the essential component of happiness.
*Strengths of Utilitarianism:
1. A clear content for ethics
2. Responding tothe situationof the agent
3. Consistency with the basic objective of human beings
*Weaknesses of Uitilitarianism:
1. Doing the calculations
2. Results Contrary to Moral Intuitions
3. Moral Luck
- Utilitarianism- Best result for everyone
- Ethical Egoism- Best result for yourself
- Hedonism- going for most pleasure and least pain
