Ethics Course Lecture

Lecture 2: Ethical Theories Part 1

Overview: In this lecture, we’ll explore some of the most influential ethical theories that form the foundation of moral philosophy. Understanding these theories will provide you with tools to analyze and approach various ethical dilemmas.

Key Theories:

1. Virtue Ethics (Aristotle)

   • Core Idea: Virtue ethics emphasizes the role of character and virtue in moral philosophy rather than either the consequences of actions (as in utilitarianism) or rules (as in deontology).
   • Key Concepts:
     • Eudaimonia: Often translated as happiness or flourishing, it is the highest good for humans, achieved through a life of virtue.
     • Virtue: A trait of character manifested in habitual action, lying at the mean between extremes of deficiency and excess (e.g., courage is the mean between cowardice and recklessness).
   • Example: A virtuous person is one who habitually acts in a way that is courageous, temperate, and just, not merely following rules but living in a way that naturally expresses these virtues.

2. Deontology (Immanuel Kant)

   • Core Idea: Deontology is an ethical theory that uses rules to distinguish right from wrong. It is sometimes described as “duty-” or “obligation-” or “rule-” based ethics.
   • Key Concepts:
     • Categorical Imperative: Kant’s central philosophical concept in deontology. It is a universal moral law that we must follow regardless of our desires (e.g., “Act only according to that maxim whereby you can, at the same time, will that it should become a universal law”).
     • Moral Duty: Actions are morally right if they are done in accordance with one’s duty, and one’s duty is determined by the categorical imperative.
   • Example: According to Kant, lying is always morally wrong because it cannot be universalized. If everyone lied, trust would be impossible, and communication would break down.

3. Utilitarianism (Jeremy Bentham & John Stuart Mill)

   • Core Idea: Utilitarianism is a consequentialist theory where the morality of an action is judged by its consequences. The goal is to maximize happiness and reduce suffering.
   • Key Concepts:
     • Greatest Happiness Principle: Actions are right insofar as they tend to promote happiness, wrong as they tend to produce the reverse of happiness.
     • Utility: Refers to the overall well-being or happiness produced by an action.
   • Example: In a utilitarian framework, an action like donating to charity is considered good if it results in a net increase in happiness or reduction in suffering for a greater number of people.
