Ethics
How to determine right and wrong, and the frameworks people use to decide.
What Ethics Is
Ethics (or moral philosophy) is the study of right and wrong conduct. Three questions sit at the centre: What should I do? What kind of person should I be? What do I owe others?
Ethics vs. Morality
| Term | Meaning | Example |
|---|---|---|
| Morality | The actual values and norms people hold | "In my culture, we value honesty" |
| Ethics | The philosophical study of morality | "Is honesty always morally required?" |
| Descriptive ethics | What people actually believe | "Most people think lying is wrong" |
| Normative ethics | What people should believe | "Lying is wrong because..." |
| Metaethics | The nature of morality itself | "Are moral facts objective?" |
The Three Major Ethical Frameworks
1. Consequentialism (Results-Based Ethics)
Core idea: Actions are right or wrong based on their consequences.
Utilitarianism
The most famous consequentialist theory, developed by Jeremy Bentham and John Stuart Mill.
| Principle | Explanation |
|---|---|
| Utility | Maximize happiness (or well-being) for all affected |
| Impartiality | Everyone's happiness counts equally |
| Aggregation | Add up total happiness minus suffering |
The Greatest Happiness Principle: An action is right if it produces the greatest good for the greatest number.
| Type | Focus | Proponent |
|---|---|---|
| Act Utilitarianism | Each action judged by consequences | Bentham |
| Rule Utilitarianism | Follow rules that maximize utility | Mill |
| Preference Utilitarianism | Satisfy preferences, not just pleasure | Singer |
Strengths:
- Clear decision procedure
- Treats everyone equally
- Focused on real-world outcomes
Weaknesses:
- Can justify terrible acts if outcomes are good enough
- Ignores individual rights
- Difficult to calculate consequences
Famous thought experiment: The Trolley Problem - Is it right to kill one person to save five?
2. Deontology (Duty-Based Ethics)
Core idea: Some actions are right or wrong regardless of consequences.
Kantian Ethics
Immanuel Kant developed the most influential deontological theory.
| Principle | Meaning |
|---|---|
| Categorical Imperative | Universal moral law that applies unconditionally |
| First Formulation | Act only according to rules you could will to be universal |
| Second Formulation | Treat humanity never merely as means, but as ends |
| Third Formulation | Act as a legislating member of the kingdom of ends |
Key Kantian concepts:
| Concept | Explanation |
|---|---|
| Good will | The only unconditionally good thing |
| Duty | Acting from moral obligation, not inclination |
| Autonomy | Self-governance through reason |
| Dignity | Intrinsic worth of rational beings |
Strengths:
- Protects individual rights
- Provides clear prohibitions (no lying, no killing)
- Respects human dignity
Weaknesses:
- Can seem inflexible
- Conflicts between duties unclear
- Ignores consequences entirely
Famous example: Kant argued that lying is always wrong, even to a murderer asking where their victim is hiding.
3. Virtue Ethics (Character-Based Ethics)
Core idea: Focus on becoming a good person, not following rules.
Aristotelian Virtue Ethics
Aristotle's Nicomachean Ethics established this tradition.
| Concept | Meaning |
|---|---|
| Eudaimonia | Flourishing, living well, the good life |
| Virtue (arete) | Excellence of character |
| The Mean | Virtue lies between excess and deficiency |
| Phronesis | Practical wisdom to apply virtues correctly |
| Habituation | Virtues developed through practice |
The Doctrine of the Mean:
| Vice (Excess) | Virtue (Mean) | Vice (Deficiency) |
|---|---|---|
| Recklessness | Courage | Cowardice |
| Prodigality | Generosity | Stinginess |
| Vanity | Proper pride | False modesty |
| Buffoonery | Wit | Boorishness |
| Obsequiousness | Friendliness | Quarrelsomeness |
Strengths:
- Holistic view of moral life
- Emphasizes character development
- Allows for context and judgment
Weaknesses:
- Doesn't give clear action guidance
- Which traits are virtues?
- Cultural variation in virtues
Comparing the Frameworks
| Situation | Utilitarian | Deontologist | Virtue Ethicist |
|---|---|---|---|
| Should I lie to protect someone? | Yes, if it produces better outcomes | No, lying is categorically wrong | What would an honest person with good judgment do? |
| Is stealing bread to feed family moral? | Depends on net happiness | Stealing violates moral law | Consider context, but dishonesty corrupts character |
| Should I break a promise? | Yes, if breaking it produces more good | No, promise-keeping is a duty | Consider loyalty as a virtue |
Other Important Ethical Theories
Care Ethics
| Principle | Explanation |
|---|---|
| Relationships central | Ethics grounded in caring relationships |
| Context matters | Particular situations over abstract rules |
| Emotion valued | Care and empathy, not just reason |
| Associated with | Carol Gilligan, Nel Noddings |
Social Contract Theory
| Principle | Explanation |
|---|---|
| Morality as agreement | Rules we'd agree to for mutual benefit |
| Rational self-interest | Foundation of moral rules |
| Key thinkers | Hobbes, Locke, Rousseau, Rawls |
Divine Command Theory
| Principle | Explanation |
|---|---|
| God determines morality | Right = what God commands |
| Euthyphro dilemma | Is it good because God commands it, or does God command it because it's good? |
| Problem | Makes morality arbitrary or God unnecessary |
Applied Ethics: Real-World Issues
Common Moral Dilemmas
| Dilemma | Key Considerations |
|---|---|
| Euthanasia | Autonomy, suffering, sanctity of life |
| Abortion | Personhood, bodily autonomy, rights |
| Capital punishment | Justice, deterrence, human dignity |
| Animal rights | Sentience, speciesism, suffering |
| Environmental ethics | Future generations, intrinsic value of nature |
| Business ethics | Profit vs. responsibility, stakeholders |
Decision-Making Framework
When facing an ethical dilemma:
- Identify the ethical issue - What makes this a moral problem?
- Gather facts - What information is relevant?
- Identify stakeholders - Who is affected?
- Consider options - What are the possible courses of action?
- Apply frameworks - What do consequentialism, deontology, and virtue ethics say?
- Seek consistency - Would I apply this reasoning universally?
- Decide and reflect - Make a choice and learn from it
Key Philosophers
| Philosopher | Era | Contribution |
|---|---|---|
| Socrates | 470-399 BCE | Examined virtues, ethical questioning |
| Plato | 428-348 BCE | The Good, justice, ideal character |
| Aristotle | 384-322 BCE | Virtue ethics, eudaimonia, practical wisdom |
| Aquinas | 1225-1274 | Natural law theory, cardinal virtues |
| Kant | 1724-1804 | Categorical imperative, duty, dignity |
| Bentham | 1748-1832 | Utilitarianism, hedonic calculus |
| Mill | 1806-1873 | Refined utilitarianism, liberty |
| Nietzsche | 1844-1900 | Critiqued morality, master/slave ethics |
| Moore | 1873-1958 | Naturalistic fallacy, non-naturalism |
| Rawls | 1921-2002 | Justice as fairness, veil of ignorance |
| Singer | 1946-present | Animal ethics, effective altruism |
Metaethical Questions
Beyond asking "what should I do?", ethics asks deeper questions:
| Question | Positions |
|---|---|
| Are moral facts objective? | Moral realism vs. anti-realism |
| Where do moral values come from? | God, reason, evolution, society |
| Can we know moral truths? | Moral knowledge vs. skepticism |
| What do moral statements mean? | Cognitivism vs. non-cognitivism |
Practical Application
Daily Ethical Thinking
| Practice | Purpose |
|---|---|
| Consider impact on others | Develop moral awareness |
| Ask "would I want this universalized?" | Kantian consistency check |
| Reflect on your character | Virtue development |
| Seek opposing viewpoints | Avoid moral blind spots |
| Admit uncertainty | Intellectual humility |
Warning Signs of Bad Moral Reasoning
| Problem | Description |
|---|---|
| Self-serving bias | Conveniently conclude what benefits you |
| Motivated reasoning | Start with conclusion, find justifications |
| Tribalism | "My group right or wrong" |
| Appeal to tradition | "We've always done it this way" |
| False equivalence | Treating all positions as equally valid |
Key Takeaways
- Three main frameworks. Consequentialism (outcomes), deontology (duties), virtue ethics (character).
- Each has strengths and weaknesses. No single theory handles every case.
- Use multiple lenses. Run a hard decision through all three; note where they agree.
- Character carries weight. Being a good person is as important as doing good acts.
- Context matters, principles still apply. Both are true at once.
- Ethics admits of reasoning. Morality is not only feelings or tradition.
- Ethical thinking is a skill. It improves with practice.
- Stay humble. Moral certainty is the failure mode to watch for.
