Western Moral Philosophers

1. Socrates (470–399 BCE) — Ethics as Self-Examination

Core Ideas

Socrates wrote nothing himself — his ideas survive through Plato's dialogues. His contribution is methodological as much as substantive: the Socratic Method and the claim that ethics begins with self-knowledge.

• "Know thyself" (Gnothi Seauton) — inscribed at Delphi; Socrates made it the foundation of ethics. Self-ignorance is the root of all moral error.
• Virtue is knowledge — no one does evil knowingly; wrongdoing is always a result of ignorance (of what is truly good). This is "Socratic intellectualism" — moral education is the solution to immorality.
• The Socratic Method (Elenchus) — questioning assumptions until contradictions emerge; the midwife method (maieutics) — drawing out truth through dialogue. Applied to governance: the officer who never questions their own assumptions is ethically dangerous.
• The unexamined life is not worth living — said at his trial before accepting death rather than abandon philosophy.
• Death over compromise — chose execution rather than stop philosophising. The model of integrity at ultimate cost.

2. Plato (428–348 BCE) — Ethics of the Just Soul & State

Core Ideas

• Theory of Forms — the physical world is a shadow of the ideal; true knowledge is of Forms (perfect, eternal archetypes). The Good (to agathon) is the highest Form — the source of truth, beauty, and being.
• The Just Soul — justice is harmony among the three parts of the soul: Reason (should govern), Spirit/Will (supports reason), Appetite (desires, must be controlled). Injustice = appetite or spirit overriding reason.
• The Just City (Republic) — corresponding three classes: Philosopher-Kings (wisdom/reason), Guardians (courage/spirit), Producers (appetite). Justice = each performing their proper function.
• Philosopher-Kings — only those who love wisdom and have contemplated the Good should govern. "Until philosophers rule, or rulers genuinely philosophise, cities will have no rest from evil."
• Allegory of the Cave — prisoners see only shadows; the philosopher who escapes sees the sun (truth) and has the duty to return and enlighten others — the obligation of the enlightened to serve the community.

3. Aristotle (384–322 BCE) — Virtue Ethics & Eudaimonia

Core Ideas

Aristotle's ethics, set out in the Nicomachean Ethics, is the founding text of virtue ethics — the most influential ethical theory for character-based civil service training.

• Eudaimonia (Flourishing/Well-being) — the ultimate goal of human life; often translated as "happiness" but better as "human flourishing" or "living well and doing well." Not a feeling but an activity — the active exercise of the soul in accordance with virtue.
• Virtue (Arete) — excellence of character; the stable disposition to feel, desire, and act appropriately. Virtues are habits — formed through practice, not innate.
• The Golden Mean (Mesotes) — every virtue is the mean between two vices: deficiency (vice of deficiency) and excess (vice of excess). Courage = mean between cowardice (deficiency) and recklessness (excess). Honesty = mean between deceptiveness and brutal bluntness.
• Moral virtues: courage, temperance, liberality, magnificence, magnanimity, proper ambition, gentleness, truthfulness, wittiness, friendliness, modesty, righteous indignation.
• Intellectual virtues: sophia (theoretical wisdom), phronesis (practical wisdom/prudence), techne (craft knowledge), nous (intuition), episteme (scientific knowledge).
• Phronesis (Practical Wisdom) — the master intellectual virtue; the ability to discern the right course of action in particular situations. Not following rules but exercising wise judgment. The civil servant cannot follow a rulebook for every situation — phronesis is what fills the gaps.
• Politics as the highest practical science — the polis (city-state) is the context in which humans achieve eudaimonia; political governance is therefore a moral project, not just a managerial one.

4. Jeremy Bentham (1748–1832) — Classical Utilitarianism

Core Ideas

Bentham founded utilitarianism — the first systematic consequentialist moral theory. Published in An Introduction to the Principles of Morals and Legislation (1789).

• The Principle of Utility (Greatest Happiness Principle) — "the greatest happiness of the greatest number" is the measure of right and wrong. An action is right if it produces more pleasure (utility) than the alternatives.
• Hedonism — pleasure and pain are the only intrinsic goods and evils. "Nature has placed mankind under the governance of two sovereign masters, pain and pleasure."
• Felicific Calculus (Hedonic Calculus) — pleasures/pains can be measured by: intensity, duration, certainty, propinquity (nearness), fecundity (likelihood of producing more), purity, extent (number affected). All pleasures are qualitatively equal — only quantity matters.
• Act Utilitarianism — judge each individual act by whether it maximises utility in that specific situation.
• Panopticon — circular prison design where all inmates are visible from one central point; extended to governance: visibility creates compliance. Precursor to modern transparency and accountability systems.

5. John Stuart Mill (1806–1873) — Refined Utilitarianism

Core Ideas

Mill refined Bentham's utilitarianism to address its crudeness, in Utilitarianism (1863) and On Liberty (1859).

• Quality of Pleasures — "it is better to be Socrates dissatisfied than a fool satisfied." Higher pleasures (intellectual, moral, aesthetic) are intrinsically more valuable than lower pleasures (physical). Those who have experienced both prefer higher pleasures.
• Rule Utilitarianism — rather than calculating utility for each act, follow rules that generally maximise utility. This prevents the "torture the innocent" problem by prohibiting certain actions whose general practice would reduce total utility.
• The Harm Principle (On Liberty) — "the only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others." Self-regarding actions are beyond state interference.
• Individual Liberty — freedom of thought, expression, and lifestyle are essential for human development. Suppressing minority views harms even the majority (which benefits from having its views challenged).
• Utilitarianism and Justice — justice is a special class of utility; protecting individual rights is a utilitarian requirement because security is the most vital of all interests.

6. Immanuel Kant (1724–1804) — Deontological Ethics

Core Ideas

Kant's moral philosophy, set out in the Groundwork for the Metaphysics of Morals (1785) and the Critique of Practical Reason (1788), is the founding text of deontological ethics — duty-based morality independent of consequences.

• Good Will — the only unconditionally good thing in the world is a good will. Talents, health, happiness — all can be used for evil; only a good will is inherently good. A good will acts from duty, not inclination or consequence.
• Duty (Pflicht) — moral action is action done from duty (aus Pflicht), not merely in accordance with duty (pflichtmässig). Acting honestly because it produces good results = acting in accordance with duty. Acting honestly because honesty is right regardless of results = acting from duty.
• The Categorical Imperative — the supreme principle of morality: an unconditional moral obligation binding on all rational beings. Kant gave three formulations:

Key Kantian Concepts

• Hypothetical imperative — "If you want X, do Y." Conditional on a desire. Not morally binding in Kant's sense.
• Categorical imperative — "Do Y." Unconditional; binding regardless of desires or consequences.
• Perfect duties — duties that admit no exceptions: do not lie, do not murder, do not break promises.
• Imperfect duties — duties that allow latitude in how and when they are fulfilled: develop your talents, help others.
• Autonomy — the capacity for self-legislation; moral agents give themselves the moral law through reason. Heteronomy = being governed by external authority or inclination (moral weakness).

7. John Rawls (1921–2002) — Justice as Fairness

Core Ideas

John Rawls' A Theory of Justice (1971) is the most influential work in 20th-century political philosophy. It provides the philosophical basis for affirmative action, welfare state, and rights-based governance.

• Original Position — a hypothetical state where rational people choose principles of justice for their society. To ensure fairness, they choose from behind a:
• Veil of Ignorance — they do not know their place in society (class, race, gender, abilities, religious beliefs). They do not know their conception of the good. They must choose principles for a society where they might occupy any position.
• Two Principles of Justice (chosen from behind the veil):

Lexical priority: First principle takes priority over the second; within the second, fair equality of opportunity takes priority over the difference principle. Liberty cannot be sacrificed for welfare gains.

Rawls vs Utilitarianism

Rawls was explicitly anti-utilitarian: "Each person possesses an inviolability founded on justice that even the welfare of society as a whole cannot override." This is the strongest philosophical argument against sacrificing minority rights for aggregate benefit.

8. Robert Nozick (1938–2002) — Libertarian Justice

Core Ideas

Nozick's Anarchy, State, and Utopia (1974) is Rawls' great rival — a libertarian response arguing that redistribution violates individual rights.

• Entitlement Theory — justice in holdings: (1) just original acquisition, (2) just transfer, (3) rectification of injustice. If acquisitions and transfers are just, the resulting distribution is just — regardless of how unequal.
• Self-ownership — each person owns themselves; therefore owns the products of their labour; taxation of earnings = forced labour = slavery.
• Minimal State — only a "night watchman" state (protecting rights, enforcing contracts) is legitimate. Redistributive welfare state is unjust because it violates individual rights.

9. Care Ethics — Noddings & Gilligan

Origins

Carol Gilligan (In a Different Voice, 1982) and Nel Noddings (Caring, 1984) developed care ethics as a critique of Kohlberg's male-biased moral development framework and Kantian abstraction.

Core Ideas

• Relationships over principles — moral life is primarily about maintaining caring relationships, not applying abstract universal rules. Morality begins in the particular, not the universal.
• Care as a moral virtue — attentiveness, responsibility, competence, and responsiveness are the core moral virtues — not justice and autonomy (Kantian) or utility (utilitarian).
• Context-sensitivity — the right action depends on the specific relationship and situation, not a universal rule applicable to all.
• Gilligan's critique of Kohlberg — Kohlberg's Stage 6 (universal principles) is not morally superior to Stage 3 (interpersonal relationships); it simply reflects a male-biased model of moral development. Women's moral reasoning emphasises care, connection, and context — equally valid.
• Nel Noddings — distinguished natural caring (spontaneous) from ethical caring (deliberate choice to care even when natural impulse is absent). The ethical ideal is the "one-caring" — person who reliably and deliberately cares for those in their purview.

10. Three Ethical Theories — Master Comparison

W.D. Ross's Prima Facie Duties — The Bridge

William David Ross (1877–1971) offered a middle path in The Right and the Good (1930): we have multiple prima facie duties (fidelity, reparation, gratitude, justice, beneficence, self-improvement, non-maleficence) that are binding unless overridden by stronger duties in a specific situation. This is more realistic than rigid Kantianism and avoids pure consequentialism.

11. Applying Theories to Governance

12. Moral Dilemmas — Which Theory Wins?

The Trolley Problem (Foot, 1967)

A runaway trolley is heading toward five people. You can divert it onto a side track where it will kill one person. Should you divert it?

• Utilitarian: Yes — five lives saved > one life lost. Redirect.
• Kantian: No — you would be using the one person as a means to save others. You may allow harm; you may not do harm.
• Virtue ethics: A phronimos would agonise but likely redirect — but the moral weight of the action must be acknowledged, not sanitised.

Governance relevance: Disaster triage, healthcare rationing, forced displacement — these are real trolley problems. UPSC case studies test exactly this reasoning.

The Fat Man Variant (Judith Jarvis Thomson)

Now you can stop the trolley by pushing a large person off a bridge. Same arithmetic: one death prevents five. But almost no one agrees with this. Why?

Because actively using a person as an instrument (Formula 2 violation) feels categorically different from diverting a threat — even with identical outcomes. This shows that deontological intuitions are deeply embedded even in people who think they are consequentialists.

Bernard Williams' Integrity Objection

Williams argued against utilitarianism: if you are required to do evil whenever it produces the most utility, you lose moral integrity — your character and commitments are always hostage to calculation. This is the philosophical argument for why civil servants cannot "just follow orders" when orders require ethical violations.

13. Epicurus (341–270 BCE) — Hedonic Ethics

Core Ideas

Epicurus founded the school of Epicureanism at "The Garden" in Athens. His central claim: pleasure (hedone) is the highest good and the goal of human life — but this is radically different from crude pleasure-seeking.

• Two kinds of pleasure — Epicurus distinguished:
  • Kinetic pleasures: active enjoyment — eating, drinking, sensory excitement. These are unstable and often followed by pain.
  • Katastematic pleasures: stable, restful states — ataraxia (tranquillity of mind, freedom from mental anxiety) and aponia (absence of bodily pain). These are the highest and most durable pleasures.
• The highest life: philosophical friendship, intellectual pleasure, moderate living, and above all freedom from fear and anxiety. Not luxury — Epicurus himself lived simply on bread, water, and cheese.
• Tetrapharmakos (four-fold remedy) — the core of Epicurean practical ethics:
  1. Don't fear God (the gods are indifferent to human affairs)
  2. Don't fear death ("When death is, I am not; when I am, death is not")
  3. What is good is easy to get (natural desires are simple and satisfiable)
  4. What is terrible is easy to endure (severe pain is short; chronic pain is bearable)
• Withdrawal from public life: Epicurus advised lathe biosas — "live hidden." Avoid politics, fame, and ambition; they generate anxiety and pain.
• Friendship (philia): the greatest external source of pleasure and security — the Epicurean community was built around deep philosophical friendship.

14. Stoicism — Reason, Virtue, and Acceptance

Core Ideas

Stoicism was founded by Zeno of Citium (c. 300 BCE) at the Stoa Poikile (Painted Porch) in Athens, and developed by Chrysippus, Epictetus (c. 50–135 CE), Seneca (c. 4 BCE–65 CE), and Marcus Aurelius (121–180 CE). It is the most practically influential ancient school of ethics for public life.

• Core claim: Virtue (arete) is the only true good. External things — wealth, health, reputation, pleasure, even life itself — are "preferred indifferents" (proegmena adiaphora): worth pursuing if they come without compromising virtue, but not genuinely good or bad in themselves.
• Logos: Universal reason pervades the cosmos. Humans uniquely share in this rational principle. To live ethically is to live "according to nature" — which for rational beings means living according to reason (kata logon).
• The Four Stoic Virtues (the only genuine goods):
  • Wisdom (phronesis / sophia) — knowing what is truly good and how to act accordingly
  • Courage (andreia) — enduring hardship and danger in accordance with reason
  • Justice (dikaiosyne) — giving others their due; fulfilling social obligations
  • Temperance (sophrosyne) — moderation and self-control over impulses
• Cosmopolitanism: All humans share in logos and are therefore members of one universal community (kosmou polites — citizen of the world). No distinction by caste, nation, gender, or status is morally fundamental. This is the ancient origin of universal human dignity.

Epictetus — The Dichotomy of Control

Epictetus (Enchiridion, c. 108 CE) formulated the most practically powerful Stoic principle:

• What is "up to us" (eph' hemin): our judgements, intentions, values, responses — our inner life and choices
• What is "not up to us" (ouk eph' hemin): body, wealth, reputation, political outcomes, others' actions, death
• Practical implication: Happiness and virtue depend only on what is up to us. Unhappiness comes from treating what is not up to us as if it were. The sage is free even in chains because freedom is an inner condition.

Marcus Aurelius — Stoicism in Power

Marcus Aurelius (Emperor of Rome 161–180 CE) is the supreme example of Stoic ethics applied to governance. His Meditations are private notes — an attempt to hold himself to Stoic standards while governing an empire.

15. Thomas Hobbes (1588–1679) — Social Contract and Human Nature

Core Ideas

Hobbes' Leviathan (1651) is the founding text of modern political philosophy and the most influential account of why human beings form states. It rests on a stark theory of human nature.

• State of Nature: Without government, humans exist in a "war of all against all" (bellum omnium contra omnes). Life in the state of nature is:
  "Solitary, poor, nasty, brutish, and short."— Thomas Hobbes, Leviathan, Chapter XIII
• Human nature: Humans are rational egoists — they act primarily to preserve themselves and satisfy their desires. Natural equality of humans means anyone can kill anyone; this creates perpetual insecurity and conflict.
• No morality in the state of nature: "The notions of right and wrong, justice and injustice, have there no place." Morality is a product of civil society and law, not a natural fact.
• Natural Right (Jus Naturale): In the state of nature, each person has the right to do whatever is necessary for self-preservation — including killing others. There are no natural moral limits.
• Laws of Nature (Lex Naturalis): Rational precepts discovered by reason — the most fundamental: seek peace where possible; and lay down the natural right to all things by contracting with others.

The Social Contract — Hobbes' Solution

• The Contract: Individuals surrender their natural liberty to a Sovereign (the Leviathan) — a monarch or assembly — in exchange for security and order. This surrender is permanent and unconditional.
• Absolute sovereignty: The Sovereign is not party to the contract; they cannot break it. The Sovereign's power is unlimited — they make law, determine justice, control the church, and maintain order. Rebellion is never justified because the alternative (state of nature) is always worse.
• Legitimacy of the state: Based entirely on its capacity to provide security. A sovereign who cannot protect subjects loses legitimacy — this is the only qualification on absolute power.

16. G.E. Moore (1873–1958) — Principia Ethica and Non-Naturalism

Core Ideas

G.E. Moore's Principia Ethica (1903) launched 20th-century analytic ethics with a deceptively simple question: "What does 'good' mean?" His answer revolutionised moral philosophy.

• "Good" is indefinable: "Good" is a simple, unanalysable, non-natural property. It cannot be defined in terms of any natural property — pleasure, happiness, evolutionary fitness, social approval, or anything observable in the physical world. Just as yellow cannot be defined by describing wavelengths (you can describe yellow, but that is not the same as the experience of yellow), "good" cannot be defined by listing natural facts.
• The Naturalistic Fallacy: The error of defining "good" in natural terms — for example:
  • "Good = pleasure" (Bentham, Epicurus)
  • "Good = what maximises evolutionary fitness" (Social Darwinism)
  • "Good = what God commands" (Divine Command Theory)
  • "Good = what society approves" (Moral Relativism)
  All of these commit the Naturalistic Fallacy — they identify "good" with some natural or metaphysical property, but this identification can always be questioned by what Moore called the Open Question Argument: "X produces pleasure — but is it good?" remains an open, non-trivial question. If "good" meant "pleasure," this question would be nonsensical.
• Intuitionism: We know "good" directly through moral intuition — a faculty of direct, non-inferential moral perception. We cannot prove goodness from natural facts; we simply see it.
• Ideal Consequentialism: Moore was a consequentialist, but not a hedonist. He held that intrinsic goods include:
  • Aesthetic beauty and the appreciation of beauty
  • Personal affection (love, friendship)
  • Knowledge
  • Pleasure (but not as the only good)
  The right action is that which produces the most intrinsic good — but intrinsic good is not reducible to pleasure.

17. Metaethics — Emotivism and Prescriptivism

What is Metaethics?

Metaethics asks foundational questions about ethics, not what we should do, but what moral statements mean, whether moral facts exist, and how (if at all) we can have moral knowledge. The major 20th-century positions emerged from and in reaction to Moore's Principia Ethica.

A. A.J. Ayer (1910–1989) — Emotivism / Logical Positivism

Alfred Jules Ayer's Language, Truth and Logic (1936) applied the Verification Principle of Logical Positivism to ethics with radical results.

• Verification Principle: A statement is cognitively meaningful (capable of being true or false) only if it is either (a) analytically true (true by definition) or (b) empirically verifiable (testable by observation). Moral statements are neither — "Stealing is wrong" is not an analytic truth, nor can it be verified by observation.
• Moral statements are expressions of emotion (exclamations):
  "Stealing is wrong" = "Boo stealing!" — an expression of disapproval, nothing more.— A.J. Ayer, Language, Truth and Logic
• Non-cognitivism: Moral statements are not descriptions of the world; they do not have truth values; they express emotional attitudes. Ethics is non-cognitive — there is no moral knowledge, only moral feeling.
• Implication: There are no objective moral truths. Moral "disagreement" is not factual disagreement — it is a clash of emotional attitudes.

B. C.L. Stevenson (1908–1979) — Emotivism with Attitude

Charles Leslie Stevenson refined Ayer's emotivism in Ethics and Language (1944), making it more sophisticated and attentive to how moral language actually works.

• Moral statements have two components:
  1. Expressive: the speaker expresses their own attitude ("I disapprove of stealing")
  2. Invitational (imperative): the speaker invites the hearer to share that attitude ("Do so as well")
  So: "Stealing is wrong" = "I disapprove of stealing; do so as well."
• Moral disagreement as attitudinal disagreement: Two people disagree morally when they have opposed attitudes about the same action — and each tries to persuade the other to change their attitude.
• Persuasion vs proof: Moral arguments work through persuasion (emotional appeals, appeals to interest) as much as through logical proof. Changing someone's beliefs about facts can change their moral attitudes.
• More sophisticated than Ayer: Stevenson accounts for the social and persuasive dimension of moral language — it is not just an exclamation but a communicative act aimed at influencing others.

C. R.M. Hare (1919–2002) — Prescriptivism

Richard Mervyn Hare, in The Language of Morals (1952) and Freedom and Reason (1963), developed prescriptivism — the most sophisticated non-cognitivist position, bridging emotive and rational accounts of ethics.

• Moral statements as prescriptions: Moral statements are not descriptions of fact but prescriptions (commands, universalised imperatives). "Stealing is wrong" = "Do not steal!" — a universal command, not an emotional outburst and not a factual claim.
• Universalisability: A moral judgement must be universalisable — if you say "act A is right in circumstances C," you are committed to saying it is right for all agents in relevantly similar circumstances C. You cannot make a special exception for yourself without logical inconsistency.
• Connection to Kant: Universalisability is the structural equivalent of Kant's categorical imperative (Universal Law formulation) — but derived from the logic of moral language, not from the nature of rational agency.
• Prescriptivism and rationality: Unlike pure emotivism, prescriptivism makes moral argument rational — you can be logically inconsistent in your moral views (by failing to universalise), and this is a genuine moral error.
• Two-level utilitarianism (later Hare): In Moral Thinking (1981), Hare argued that moral thinking operates at two levels: (a) intuitive level — following prima facie rules in everyday life; (b) critical level — utilitarian calculation when rules conflict. Ultimately resolves to preference utilitarianism.
