Ethics
How to determine right and wrong, and frameworks for moral decision-making.
What is Ethics?
Ethics (or moral philosophy) is the systematic study of right and wrong conduct. It asks: 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 |

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 exist - Consequentialism (outcomes), deontology (duties), virtue ethics (character)
- Each has strengths and weaknesses - No single theory handles all cases perfectly
- Use multiple lenses - Apply different frameworks to get fuller picture
- Character matters - Being a good person is as important as doing good acts
- Context is relevant - But some principles may be universal
- Reason about ethics - Morality isn't just feelings or tradition
- Practice ethical thinking - Like any skill, it improves with use
- Stay humble - Moral certainty can be dangerous
