Introduction to Ethics and Philosophy

TL;DR

Ethics and philosophy explore fundamental questions about existence, knowledge, values, reason, and mind. Ethics specifically focuses on what’s morally right or wrong, guiding human behavior and decisions. Understanding these fields helps you develop critical thinking and a more thoughtful approach to life.

1. The Mental Model

Think of philosophy as the big picture questions about reality and human experience, and ethics as a specific branch within it that asks how we should live and act. It’s like understanding the rules of a game (ethics) by first understanding the game itself and why we play it (philosophy).

2. The Core Material

Philosophy is a vast field, but it generally tackles big questions that science often can’t definitively answer. It encourages critical thinking, questioning assumptions, and building reasoned arguments. You'll encounter major branches like:

• Metaphysics: What is reality? Does God exist? What is the nature of time?
• Epistemology: How do we know what we know? What is truth? Can we ever truly know anything?
• Ethics (Moral Philosophy): How should we live? What is good? What is justice?
• Logic: The study of valid reasoning. How do we construct sound arguments?
• Aesthetics: What is beauty? What is art?

Ethics, our main focus here, dives into human morality. It's not just about personal feelings, but about trying to find reasoned principles that can guide behavior. There are generally three main approaches to ethical theory:

Normative Ethics: What Should We Do?

This branch aims to establish moral norms or standards of conduct. It seeks to answer practical questions about what is morally permissible or obligatory.

• Deontology (Duty-based ethics): Focuses on duties or rules. Actions are good if they follow a moral rule, regardless of the consequences. Think of Immanuel Kant and his categorical imperative ("Act only according to that maxim whereby you can at the same time will that it should become a universal law").
• Consequentialism (Outcome-based ethics): Judges the morality of an action based on its outcomes or consequences. Utilitarianism, a prominent form, argues that the best action is the one that maximizes overall happiness or well-being for the greatest number of people.
• Virtue Ethics (Character-based ethics): Focuses on the character of the moral agent rather than specific actions or consequences. It asks, "What kind of person should I be?" rather than "What should I do in this situation?" Aristotle is a key figure here, emphasizing the development of virtues like courage, honesty, and wisdom.

Metaethics: What Do Moral Terms Mean?

This branch explores the nature of moral judgments. It asks questions like: What does "good" mean? Are moral truths objective or subjective? Are moral statements expressions of emotion or statements about facts?

Applied Ethics: How Do We Apply It?

This branch examines specific controversial issues using philosophical methods. Examples include medical ethics (e.g., abortion, euthanasia), business ethics, environmental ethics, and artificial intelligence ethics.

3. Worked Example

Let's say you find a wallet full of cash on the street. What should you do?

• Deontological Approach: A deontologist might argue that you have a duty to return lost property. There's an inherent moral rule against stealing, and a rule to be honest. The consequences (e.g., you need the money, or the owner won't even know it was you) don't change your duty. Your action is right because it adheres to a universal moral law.
• Consequentialist Approach (Utilitarianism): A utilitarian would consider the outcomes. If returning the wallet makes the owner very happy and relieves their distress, while keeping it only gives you temporary pleasure (and potentially guilt), returning it would likely lead to the greatest overall happiness. If the owner is very wealthy and you are starving, a utilitarian might even argue that keeping a small portion could create greater good, but typically, the negative consequences of undermining trust and the positive impact on the owner would favor returning it.
• Virtue Ethics Approach: A virtue ethicist would ask what a virtuous person would do. A virtuous person would embody honesty, integrity, and perhaps compassion. They wouldn't consider keeping the wallet because it wouldn't align with the kind of character they strive to be. Returning the wallet demonstrates these virtues, reinforcing good character.

Each approach leads to the same action (returning the wallet) in this simple case, but for very different reasons. This shows how ethical frameworks provide different lenses for moral reasoning.

4. Key Takeaways

• Philosophy tackles fundamental questions about existence, knowledge, values, reason, and beauty.
• Ethics is the branch of philosophy specifically concerned with morality – what's right, wrong, good, and bad.
• Deontology focuses on duties and rules, judging actions based on adherence to moral principles.
• Consequentialism evaluates actions based on their outcomes, aiming to maximize overall good (e.g., happiness).
• Virtue ethics emphasizes the development of a good character and asking what a virtuous person would do.
• Understanding these frameworks helps you systematically analyze moral dilemmas and develop reasoned arguments.
• Ethics is not just about personal feelings; it's about reasoned moral principles.

Common Mistakes to Avoid:
- Don't confuse personal feelings or societal norms with universal ethical principles.
- Don't assume there's always one "right" answer that all ethical frameworks will agree on, especially in complex dilemmas.
- Don't dismiss philosophical questions as irrelevant; they shape how we think and act.
- Don't mix up the different ethical theories; each has its own distinct focus (rules, outcomes, or character).

5. Now Try It

Think about a moral dilemma you've faced recently, even a small one (e.g., whether to tell a friend a harsh truth, or if it's okay to download a movie illegally). For that dilemma, try to explain what you did or would do using each of the three normative ethical theories: deontology, consequentialism, and virtue ethics. Don't worry about which one is "correct," just try to apply each framework's reasoning to your specific situation. What success looks like: You can articulate a different rationale for your action (or inaction) from the perspective of each of the three theories.
