# Western moral thinkers: Aristotle, Kant, Mill, Rawls

Aristotle's virtue ethics, Kant's deontology, Mill's utilitarianism and Rawls's justice as fairness—mapped to GS-4 quotation and case-study application.

## The four pillars of Western ethics

Western moral philosophy gives GS-4 candidates four self-contained frameworks, each answering the question *what makes an act right?* differently. Mastering the contrast between them is the single most reusable asset in the paper.

### Aristotle (384–322 BCE): virtue ethics

In the *Nicomachean Ethics*, Aristotle locates morality not in rules or consequences but in **character**. The goal of life is *eudaimonia*—human flourishing, often mistranslated as 'happiness' but closer to 'living well'. Virtue (*arete*) is a settled disposition to act rightly, acquired by habituation, not by instruction. His central tool is the **Doctrine of the Mean**: every virtue is a midpoint between two vices of excess and deficiency. Courage lies between cowardice and recklessness; generosity between miserliness and prodigality. Crucially, the mean is determined by *phronesis* (practical wisdom)—context-sensitive judgement, not a mathematical average. For a civil servant, this translates into integrity as a cultivated habit rather than a one-time choice.

### Immanuel Kant (1724–1804): deontology

In the *Groundwork of the Metaphysics of Morals* (1785), Kant grounds morality in **duty and reason**, independent of consequences. An act has moral worth only if done from duty, guided by the **Categorical Imperative**. Its first formulation: *act only on that maxim you can will to become a universal law*. The second (the Formula of Humanity): *treat humanity, whether in your own person or another, always as an end and never merely as a means*. Kant rejects lying, coercion, and bribery absolutely—because universalising them is self-contradictory. For administration, Kant supplies the language of **non-negotiable duty**: a rule cannot bend for convenience.

### John Stuart Mill (1806–1873): utilitarianism

Building on Bentham, Mill's *Utilitarianism* (1863) defines the right act as the one producing **the greatest happiness of the greatest number**. He refines Bentham's crude hedonic calculus by distinguishing **higher (intellectual/moral) pleasures from lower (bodily) ones**—'better to be a Socrates dissatisfied than a fool satisfied'. Utilitarianism is the working logic of **public policy**: cost-benefit analysis, welfare economics, and resource allocation all assume it. Its weakness, heavily tested, is that it can justify sacrificing a minority for aggregate gain.

### John Rawls (1921–2002): justice as fairness

In *A Theory of Justice* (1971), Rawls answers utilitarianism's blind spot. Behind a **veil of ignorance** in the 'original position'—not knowing your class, talents, or gender—rational agents would choose two principles: (1) equal basic liberties for all; (2) the **Difference Principle**: social and economic inequalities are just only if they benefit the **least advantaged**. Rawls thus fuses liberty with redistributive justice and underwrites affirmative action and welfare-state design.
