Ethics

Core Principle: Ethics should focus on the character of the moral agent rather than specific rules or consequences. The good life is achieved through the cultivation of virtues — stable dispositions to act, feel, and think in excellent ways.

Aristotle argued that virtues are cultivated through habit and practice. Courage, temperance, justice, and wisdom are not innate but developed through repeated action. The virtuous person acts from a stable disposition, finding the mean between extremes — courage as the mean between cowardice and recklessness. Eudaimonia (human flourishing) is the ultimate goal, achieved through the exercise of virtue in accordance with reason.

Key Arguments: (1) Moral life is too complex to be captured by rules; we need wisdom and good character. (2) Virtue ethics emphasizes moral development and education. (3) The virtuous person perceives the morally salient features of a situation intuitively.

Criticisms: (1) It seems to lack action-guidance — what should I do in this specific case? (2) The concept of "the good life" may be culturally relative.

Core Principle: The morally right action is the one that produces the greatest amount of good (happiness, well-being, preference satisfaction) for the greatest number of people. Ethics is fundamentally about maximizing welfare.

Jeremy Bentham developed the classical version, arguing that pleasure and pain are the sovereign masters of human life. His "felicific calculus" quantified pleasure by intensity, duration, certainty, and other dimensions. John Stuart Mill refined this, distinguishing higher and lower pleasures and arguing that quality of pleasure matters, not just quantity. Mill famously wrote: "It is better to be Socrates dissatisfied than a fool satisfied."

Key Arguments: (1) Consequences are what ultimately matter — intentions alone don't make an action right. (2) Utilitarianism is egalitarian — everyone's happiness counts equally. (3) It provides a clear, measurable criterion for moral evaluation.

Criticisms: (1) The utility monster problem — a being that gains immense utility from resources could justify taking from everyone else. (2) Justice objection — utilitarianism might justify sacrificing individuals for the greater good. (3) Demandingness — it seems to require too much of us.

Core Principle: Morality is grounded in duty and rules, not consequences. Certain actions are right or wrong in themselves, regardless of their outcomes. We have moral obligations that must be respected, and people must never be treated merely as means to an end.

Immanuel Kant developed the most influential deontological system. His categorical imperative provides two key formulations: (1) Act only according to that maxim which you can will to become a universal law. (2) Treat humanity, whether in your own person or in that of another, always as an end and never merely as a means. Kant argued that moral reasoning is based on pure practical reason, not on empirical facts about happiness or consequences.

Key Arguments: (1) Some things are intrinsically wrong — torture, slavery, lying — regardless of consequences. (2) Human dignity demands respect for autonomy and rational agency. (3) Moral rules are universal and impartial.

Criticisms: (1) The absoluteness of rules leads to counterintuitive results (Kant's claim that one must not lie even to a murderer at the door). (2) Conflicts between duties are not easily resolved. (3) It ignores the moral significance of consequences entirely.

Core Principle: Morality is fundamentally about relationships and care for others, not abstract principles. Care ethics emphasizes empathy, compassion, and responsiveness to the needs of particular others rather than impartial rules.

Carol Gilligan criticized Lawrence Kohlberg's model of moral development as biased toward male perspectives, arguing that women often approach moral problems through an "ethics of care" — attending to relationships, responsibilities, and the concrete needs of others. Nel Noddings developed this into a comprehensive ethical theory, arguing that caring is the foundation of moral life and that our primary moral obligation is to maintain caring relationships.

Key Arguments: (1) Traditional ethics overemphasizes abstraction and impartiality at the expense of concrete relationships. (2) Moral development is relational, not merely rational. (3) Vulnerability and interdependence are central to the human condition.

Criticisms: (1) Care ethics may be too parochial — it risks favoring those close to us over distant strangers. (2) It may reinforce gender stereotypes by associating women with care. (3) It struggles with issues of justice at the societal level.

Core Principle: Morality is grounded in human nature and the natural order. Natural law theory holds that there are objective moral truths discoverable through reason, rooted in the nature of things and often derived from God's design of the universe.

Thomas Aquinas synthesized Aristotelian philosophy with Christian theology, arguing that natural law is the rational creature's participation in the eternal law of God. The first principle of practical reason is to do good and avoid evil. From this, Aquinas derived specific precepts: preserve life, live in society, seek truth, and reproduce. Modern natural law theorists like John Finnis have reinterpreted this tradition, grounding morality in basic human goods (life, knowledge, friendship, etc.).

Key Arguments: (1) Human nature provides an objective foundation for morality. (2) Basic goods are self-evident and incommensurable. (3) Moral reasoning is a form of practical reason, not deduction from abstract principles.

Criticisms: (1) The naturalistic fallacy — deriving "ought" from "is." (2) Human nature is too varied and contested to ground specific moral rules. (3) The theory is closely tied to Catholic theology, limiting its appeal to secular ethics.

Core Principle: Morality and political obligation arise from an implicit or explicit agreement among individuals to form a society and abide by its rules for mutual benefit. Morality is a system of rules that rational individuals would agree to under fair conditions.

Thomas Hobbes argued that in the state of nature, life would be "solitary, poor, nasty, brutish, and short" — a war of all against all. Rational individuals would consent to surrender some freedoms to a sovereign in exchange for security and order. Locke emphasized natural rights (life, liberty, property) and government by consent. Rousseau introduced the "general will" — legitimate government reflects the collective will of the people oriented toward the common good.

Key Arguments: (1) Morality is instrumentally useful — it solves coordination problems. (2) Legitimate authority requires consent. (3) Justice is a matter of fair terms of cooperation.

Criticisms: (1) The state of nature is a fiction — people are always already in social relationships. (2) Consent is often tacit or coerced, not genuine. (3) The theory struggles to account for moral obligations to those who don't participate in the contract (future generations, animals).

Core Principle: Moral truths are not universal but relative to culture, society, or individual perspective. There are no objective, mind-independent moral facts — what is right or wrong depends on the moral framework of the community or individual in question.

Cultural relativism holds that moral standards are determined by cultural practices — what is right in one culture may be wrong in another, and there is no neutral standpoint from which to judge between them. Descriptive relativism observes cross-cultural moral variation as a fact. Meta-ethical relativism goes further, arguing that moral statements are true only relative to a framework.

Key Arguments: (1) Empirical observation reveals vast moral disagreement across cultures. (2) Cultural practices shape moral intuitions in deep ways. (3) Moral relativism promotes tolerance by avoiding ethnocentrism.

Criticisms: (1) The tolerance paradox — if morality is relative, is tolerance itself relative? (2) Moral reformers (like abolitionists) challenge their own culture's morality, which seems to require a standard beyond cultural consensus. (3) Some moral truths (e.g., genocide is wrong) seem universally valid.

Core Principle: There are objective moral facts that exist independently of human beliefs, attitudes, or conventions. Moral statements can be true or false in the way that factual statements about the world can be true or false. Some actions are genuinely right or wrong, regardless of what anyone thinks.

Moral realists argue that moral facts are part of the fabric of reality. Naturalistic moral realism identifies moral facts with natural facts (e.g., what promotes well-being). Non-naturalistic moral realism (G.E. Moore, Russ Shafer-Landau) holds that moral properties are sui generis — unique, irreducible properties that cannot be identified with natural properties. Moore's "open question argument" supports this: for any natural property N, it always makes sense to ask "But is N really good?" — suggesting goodness is not identical to any natural property.

Key Arguments: (1) Our moral experience presents moral facts as objective. (2) Moral disagreement suggests we are disagreeing about something real, not just expressing preferences. (3) Moral progress implies movement toward objectively better moral standards.

Criticisms: (1) Metaphysical queerness — where do moral facts exist? How do we access them? (2) Epistemological worries — how do we know moral facts? (3) Disagreement is persistent and seems intractable, unlike scientific disagreement.

Core Principle: Existence precedes essence — there is no fixed human nature or predetermined moral order. We are "condemned to be free," and authenticity — living in accordance with one's own freely chosen values — is the highest moral achievement.

Jean-Paul Sartre argued that we are radically free and must take full responsibility for our choices. There is no God, no objective values, and no excuse for bad faith (self-deception about one's freedom). Simone de Beauvoir extended existentialism to ethics and feminism, arguing in The Ethics of Ambiguity that freedom must be exercised in a way that respects the freedom of others. Authentic freedom requires engagement with the world and commitment to projects that give life meaning.

Key Arguments: (1) We create our values through free choice — there is no pre-given moral order. (2) Bad faith — denying one's freedom — is the fundamental moral failing. (3) Authenticity requires acknowledging the ambiguity of existence and the tension between freedom and facticity.

Criticisms: (1) Radical freedom seems to undermine moral obligation — if I choose my values, why must I choose any particular ones? (2) The emphasis on individual authenticity may neglect social and political dimensions of morality. (3) It provides little concrete guidance for moral decision-making.

Core Principle: Feminist ethics critiques traditional moral theories for their gender bias and patriarchal assumptions, and seeks to develop ethical frameworks that take seriously the experiences, perspectives, and oppression of women and other marginalized groups.

Feminist ethics examines how power structures, social norms, and cultural practices perpetuate gender inequality. It challenges the public/private distinction that has historically excluded domestic labor, care work, and sexual violence from ethical and political scrutiny. Intersectional feminism (Kimberlé Crenshaw) highlights how gender oppression intersects with race, class, sexuality, and other axes of identity.

Key Arguments: (1) Traditional ethics has been shaped by male perspectives and has marginalized women's moral experiences. (2) Concepts like autonomy, justice, and dignity must be reexamined in light of structural oppression. (3) Ethics must attend to power, embodiment, and social context.

Criticisms: (1) Feminist ethics is not a unified theory but a diverse collection of approaches. (2) It may overemphasize difference between men's and women's moral perspectives. (3) Some versions risk essentialism by attributing specific moral qualities to women.
