Why This Matters

When you encounter ethics questions on an exam, you're not just being asked to define theories—you're being tested on your ability to apply different moral frameworks to real-world dilemmas and explain why they lead to different conclusions. Understanding these theories means grasping the fundamental question each one answers: Should we focus on outcomes, duties, character, relationships, or something else entirely when determining right from wrong?

The theories in this guide represent centuries of philosophical debate about the foundations of morality. Each offers a distinct lens for evaluating actions, and exam questions frequently ask you to compare approaches or identify which theory best addresses a particular scenario. Don't just memorize names and definitions—know what makes each theory unique, where they overlap, and where they fundamentally disagree.


Consequence-Based Theories

These theories share a common premise: the morality of an action depends on what happens as a result. They look forward to outcomes rather than backward to intentions or rules.

Consequentialism

  • Morality is determined solely by results—an action is right if it produces good outcomes, wrong if it produces bad ones
  • Broader category that encompasses multiple theories, including utilitarianism, but can weigh factors like rights and justice alongside happiness
  • Forward-looking framework that requires predicting and evaluating the effects of choices on all affected parties

Utilitarianism

  • Greatest happiness principle—the right action maximizes overall well-being or utility for the greatest number of people
  • Bentham vs. Mill distinction matters: Bentham measured pleasure quantitatively, while Mill argued some pleasures are qualitatively superior to others
  • Calculative approach that weighs costs and benefits, making it practical for policy decisions but challenging when outcomes are uncertain

Ethical Egoism

  • Self-interest as moral guide—individuals ought to act in ways that maximize their own long-term benefit
  • Two forms to distinguish: personal egoism (I should pursue my interests) versus universal egoism (everyone should pursue their own interests)
  • Controversial implications for altruism and cooperation, though proponents argue enlightened self-interest ultimately benefits society

Compare: Utilitarianism vs. Ethical Egoism—both evaluate actions by consequences, but utilitarianism considers everyone's well-being equally while egoism prioritizes the agent's own interests. If an exam asks about self-sacrifice, this contrast is your key example.


Duty-Based Theories

Rather than asking "what will happen?", these theories ask "what am I obligated to do?" The rightness of an action comes from following moral rules or commands, regardless of outcomes.

Deontological Ethics (Kantian Ethics)

  • Categorical imperative is the core test: act only according to principles you could will to become universal laws for everyone
  • Intention matters more than results—a morally good action done from duty has worth even if it fails to achieve good outcomes
  • Some actions are inherently wrong (lying, breaking promises) regardless of circumstances, making this theory absolutist in nature

Divine Command Theory

  • God's will defines morality—actions are right because God commands them, wrong because God forbids them
  • Euthyphro dilemma is the classic challenge: Is something good because God commands it, or does God command it because it's good?
  • Faith-based foundation ties ethics to religious belief, raising questions about moral knowledge for non-believers

Natural Law Theory

  • Moral truths discoverable through reason—ethical principles are embedded in human nature and the natural order
  • Aristotle to Aquinas lineage developed this framework, arguing that rational reflection reveals inherent human goods and purposes
  • Universal and objective standards exist independent of culture or divine revelation, accessible to anyone through careful reasoning

Compare: Kantian Ethics vs. Divine Command Theory—both ground morality in duties rather than consequences, but Kant locates moral authority in reason itself while Divine Command Theory locates it in God's will. This matters for questions about secular versus religious ethics.


Character-Based Theories

These approaches shift focus from what should I do? to what kind of person should I be? Moral development is about cultivating the right traits over time.

Virtue Ethics

  • Character over rules—moral excellence comes from developing virtues like courage, temperance, justice, and practical wisdom
  • Aristotelian foundation emphasizes that virtues are habits formed through practice, leading to eudaimonia (human flourishing)
  • Context-sensitive judgments require the virtuous person to discern the right action in each situation, rejecting rigid rule-following

Compare: Virtue Ethics vs. Deontological Ethics—both care about the moral agent, but deontology asks "did you follow the rule?" while virtue ethics asks "did you act as a person of good character would?" Virtue ethics allows more flexibility in particular situations.


Relationship and Agreement-Based Theories

These theories ground morality in human connections—either formal agreements that create society or the caring relationships that sustain it.

Social Contract Theory

  • Morality emerges from agreement—individuals consent (explicitly or implicitly) to rules that enable cooperative social life
  • Hobbes, Locke, and Rousseau differ significantly: Hobbes saw the contract as escape from brutal nature; Locke emphasized protecting natural rights; Rousseau focused on the general will
  • Legitimacy of authority is central—governments and laws are justified only if they reflect the consent of the governed

Care Ethics

  • Relationships are morally primary—ethical decisions should prioritize empathy, responsiveness, and maintaining connections over abstract principles
  • Feminist origins in Carol Gilligan's critique of male-centered moral development theories that privileged justice over care
  • Context and particularity matter—rejects the idea that good ethics means applying universal rules impartially to everyone

Compare: Social Contract Theory vs. Care Ethics—both emphasize human relationships, but social contract theory focuses on formal agreements between autonomous individuals while care ethics emphasizes emotional bonds and interdependence. Care ethics challenges the social contract's assumption that we're primarily self-interested bargainers.


Meta-Ethical Perspectives

These theories step back to ask: What is the nature of morality itself? Rather than prescribing actions, they examine the foundations of ethical claims.

Moral Relativism

  • No universal moral truths—ethical standards vary across cultures, historical periods, and social contexts
  • Descriptive vs. normative distinction: descriptive relativism observes moral diversity; normative relativism concludes no culture's values are objectively superior
  • Tolerance implications cut both ways—relativism supports cultural humility but struggles to condemn practices like oppression or genocide

Compare: Natural Law Theory vs. Moral Relativism—these represent opposite poles on whether objective moral truths exist. Natural law claims reason can discover universal principles; relativism denies any cross-cultural moral standards. Exam questions about human rights often hinge on this debate.

Self-Check Questions

  1. Which two theories both emphasize consequences but disagree about whose well-being matters most? Explain the key difference.

  2. A hospital has one dose of medicine and must choose between saving one famous scientist or five unknown patients. Which theory would most clearly support saving the five, and which might challenge that conclusion? Why?

  3. Compare and contrast how Kantian Ethics and Virtue Ethics would evaluate someone who lies to protect a friend. What does each theory prioritize?

  4. If an FRQ asks you to defend universal human rights against a moral relativist critique, which theory provides your strongest counterargument? Explain your reasoning.

  5. Both Social Contract Theory and Care Ethics reject purely individualistic approaches to morality. How do their visions of human relationships differ, and what does each emphasize as the basis for ethical obligation?
