Prerequisites

The Hook: The Collector’s Dilemma

Connect

Imagine a Collector in one of Chhattisgarh’s tribal districts. A proposed irrigation dam will bring water to tens of thousands of farmers but submerge a few villages, displacing a few hundred tribal families. Three advisers walk in.

  • Bentham’s adviser says: add up the pleasure and pain. More people gain than lose, so build it.
  • Mill’s adviser adds: count the quality of what is lost (culture, sacred groves, community) and protect the minority’s liberty.
  • Kant’s adviser says: whatever the numbers, you may not use those families merely as a means to others’ prosperity. They must be treated as ends: consulted, compensated and respected.

Which adviser is right? Indian law tries to satisfy all three: the 2013 land acquisition law requires a social impact assessment, consent in specified cases, and rehabilitation. This page explains the three ways of thinking behind such rules.

Why it matters: Kant and the utilitarians are the two poles of modern ethics: deontology (duty-based) and consequentialism (outcome-based). GS-IV answers on ethics, rights, welfare policy and free speech are stronger when they name these frameworks precisely.


Immanuel Kant (कांट), 1724–1804

ItemDetail
LivedKönigsberg, Prussia (now Kaliningrad, Russia); rarely travelled far from it
Major worksCritique of Pure Reason (1781); Groundwork of the Metaphysics of Morals (1785); Critique of Practical Reason (1788); Critique of Judgment (1790); Perpetual Peace (1795)
Essay“What is Enlightenment?” (1784): “Sapere aude” — “dare to know”, have the courage to use your own understanding
ApproachDeontology (कर्तव्यवाद): an act is right because of the principle behind it, not its consequences

Core ethical ideas

  1. Good will (शुभ संकल्प): the only thing good without qualification is a good will. Intelligence, wealth or courage can serve evil; a good will cannot.
  2. Duty for duty’s sake (कर्तव्य के लिए कर्तव्य): an act has moral worth only if done from duty, not merely in line with duty or from inclination. A shopkeeper who is honest only because honesty is good for business acts in accordance with duty, not from duty.
  3. Hypothetical vs categorical imperatives:
    • Hypothetical: “If you want X, do Y” (conditional on a goal).
    • Categorical (निरपेक्ष आदेश): “Do Y”, binding on every rational being regardless of goals. Morality consists of categorical imperatives.
  4. Formulations of the categorical imperative:
    • Universal law: act only on that maxim which you can at the same time will to become a universal law. (Lying fails: if everyone lied, promises and trust would collapse.)
    • Humanity as an end: treat humanity, in yourself and in others, always as an end and never merely as a means.
    • Kingdom of ends: act as a member of a community of rational beings who each make and obey universal moral laws.
  5. Autonomy (स्वायत्तता): a moral agent gives the moral law to himself through reason. Dignity comes from this rational autonomy, so every person has dignity, not a price.

Political ideas

  • Perpetual Peace (1795) proposed republican constitutions, a federation of free states and “cosmopolitan right”, ideas often cited as forerunners of the League of Nations and the United Nations. See International Organisations.

Criticism

  • Rigid: if lying is always wrong, may one not lie to a murderer asking where a friend is hiding? Critics say Kant ignores consequences.
  • Conflicting duties: offers no clear way to choose when two duties clash.
  • Formal: universalisability tells us what is consistent, not always what is good.

Relevance to ethics and governance

  • Human dignity: the idea that people are ends, not means, underlies the Supreme Court’s reading of Article 21 as the right to live with dignity.
  • Integrity without an audience: a Kantian officer refuses a bribe because it is wrong, not because he might be caught.
  • Rule-based, impartial administration: apply the rule you would accept for everyone, including yourself and your relatives.
  • Rights as limits on welfare calculations: no development target justifies forced displacement or custodial torture.

Jeremy Bentham (बेंथम), 1748–1832

ItemDetail
CountryEngland; trained in law, became a law reformer
Main workAn Introduction to the Principles of Morals and Legislation (printed 1780, published 1789)
Opening line“Nature has placed mankind under the governance of two sovereign masters, pain and pleasure.”
PrincipleUtility: the right action or law produces “the greatest happiness of the greatest number” (अधिकतम लोगों का अधिकतम सुख)
SchoolFounder of classical utilitarianism (उपयोगितावाद), a form of consequentialism

Core ideas

  1. Psychological hedonism: people in fact seek pleasure and avoid pain.
  2. Ethical hedonism: the right act is the one that maximises total pleasure minus pain for all affected; each person counts for one, and no one for more than one.
  3. Quantitative utilitarianism: pleasures differ only in quantity, not quality. His well-known remark that, prejudice apart, the game of push-pin is of equal value with poetry expresses this.
  4. Hedonic (felicific) calculus (सुखवादी गणना): seven dimensions to measure a pleasure or pain: intensity, duration, certainty, propinquity (nearness), fecundity, purity, extent (number of people affected).
  5. Rejection of natural rights: he called natural and imprescriptible rights “nonsense upon stilts”. Rights, for Bentham, are created by law.
  6. Sanctions: physical, political (legal), moral (popular) and religious sanctions push individuals towards the general happiness.

Bentham the reformer

  • Legal codification, prison reform and the Panopticon (a circular prison in which one watchman can observe all inmates without being seen). Michel Foucault later used the Panopticon as a metaphor for modern surveillance.
  • Supported democratic reforms, secret ballot, and the decriminalisation of victimless acts; argued for humane treatment of animals (“the question is not, Can they reason? nor, Can they talk? but, Can they suffer?”).

Criticism

  • Tyranny of the majority: the happiness of the many could justify sacrificing a minority.
  • Pleasures cannot be measured or compared across persons in practice.
  • Ignores justice, rights and motives; a “pig philosophy” according to critics, because it ranks all pleasures alike.

Relevance to public policy

  • Cost–benefit analysis of projects and schemes; targeting welfare where it does the most good.
  • Outcome-based governance: measuring results rather than inputs (outcome budgets, dashboards).
  • Prison and police reform and codified, clear laws.

John Stuart Mill (जे. एस. मिल), 1806–1873

ItemDetail
CountryEngland; son of James Mill (Bentham’s close associate), rigorously home-educated
India linkWorked at the East India Company’s London office, the Examiner’s office for Indian correspondence, from 1823 until the Company was abolished in 1858
Major worksOn Liberty (1859); Considerations on Representative Government (1861); Utilitarianism (1861 in a magazine; book 1863); The Subjection of Women (1869)
Public lifeMember of Parliament (1865–68); moved an amendment in 1867 to give women the vote

Qualitative utilitarianism

  • Accepted the greatest happiness principle but held that pleasures differ in quality: higher (intellectual, moral, aesthetic) pleasures are superior to lower (bodily) ones.
  • “It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.”
  • The judge of quality is a competent judge who has experienced both kinds.

On Liberty: the harm principle

  • Harm principle (हानि सिद्धांत): the only purpose for which power can rightfully be exercised over any member of a civilised community, against his will, is to prevent harm to others. A person’s own good is not a sufficient reason.
  • Self-regarding vs other-regarding actions: the State may regulate only conduct that affects others.
  • Freedom of thought and expression: silencing an opinion is wrong because (a) it may be true, (b) even if false it may contain part of the truth, (c) even a true opinion held without challenge becomes “dead dogma”.
  • Individuality and experiments in living are essential for human progress.
  • Warned against the “tyranny of the majority” and of social custom, not only of governments. (The phrase is also associated with Alexis de Tocqueville.)

Representative government and equality

  • Representative government is the ideal form, but requires an educated, active citizenry.
  • Supported proportional representation (Thomas Hare’s scheme) to protect minorities; proposed extra votes for the educated (plural voting).
  • The Subjection of Women argued for full legal equality of the sexes, a pioneering liberal feminist text. Mill credited his wife, Harriet Taylor Mill, with shaping his views on women.

Criticism

  • Liberalism with limits: On Liberty excludes “backward” societies from the liberty principle and accepts despotism over them “provided the end be their improvement”, a justification of colonial rule over India.
  • The line between self-regarding and other-regarding acts is hard to draw.
  • Ranking “higher” pleasures smuggles in values beyond utility.

Relevance to governance

  • Free speech and dissent: Article 19(1)(a) and its “reasonable restrictions” in 19(2) follow a broadly Millian logic. Courts have struck down vague restrictions on speech, for example Section 66A of the IT Act in Shreya Singhal (2015).
  • Paternalism debates: helmet laws, prohibition, online gaming bans and tobacco controls are all argued in terms of Mill’s harm principle.
  • Gender equality and minority representation in a plural democracy.

Memory Tricks

Kant's formulas: U-H-K
Universal law, Humanity as an end, Kingdom of ends — “Use Humans Kindly”. Books in order: Pure (1781) → Groundwork (1785) → Practical (1788): “Please Give Praise”.
Bentham's seven dimensions: 'I Do Count Pleasure For Pure Extent'
Intensity, Duration, Certainty, Propinquity, Fecundity, Purity, Extent.
Bentham counts, Mill weighs
Bentham = quantity (push-pin equals poetry). Mill = quality (Socrates dissatisfied beats a fool satisfied).

Don’t Confuse

ThisvsThat
Bentham — quantitative utilitarianism; Introduction to the Principles (1789)vsMill — qualitative utilitarianism; Utilitarianism (1861/1863)
Hypothetical imperative — “if you want X, do Y”vsCategorical imperative — “do Y”, unconditionally
Acting in accordance with duty (for profit or fear)vsActing from duty (the only kind with moral worth for Kant)
Harm principle — interfere only to prevent harm to others (Mill)vsPaternalism — interfere for the person’s own good (rejected by Mill for adults)
James Mill — father; History of British IndiavsJ.S. Mill — son; On Liberty

Common Mistakes

Exam traps
  • “Kant judged actions by their consequences.” No. Kant is the classic deontologist; consequences do not determine moral worth.
  • “Mill rejected utilitarianism.” No. He refined it by distinguishing higher and lower pleasures.
  • “Bentham was a champion of natural rights.” No. He called natural rights “nonsense upon stilts”.
  • “The harm principle allows the State to stop a person from harming himself.” Not for competent adults. Mill allows interference only to prevent harm to others.
  • “Mill applied his liberty principle to all societies.” He explicitly excluded societies he considered “backward”, a point used to critique liberal imperialism.

Practice

All questions below are original practice questions written in CGPSC style. They are not previous-year questions.

Level 1: Foundation

  1. According to Kant, the only thing good without qualification is a ______.
  2. Bentham’s book An Introduction to the Principles of Morals and Legislation was published in ______.
  3. Mill’s principle that power may be exercised over an individual only to prevent harm to others appears in ______ (1859).
Answers
  1. good will
  2. 1789 (printed 1780)
  3. On Liberty

Level 2: Prelims-style MCQs

Q1. Consider the following statements:

  1. Kant held that an action done only out of self-interest, even if it matches duty, has no moral worth.
  2. Bentham distinguished higher and lower pleasures by quality.
  3. Mill wrote The Subjection of Women.

Which of the statements given above is/are correct?

  • (a) 1 only
  • (b) 2 and 3 only
  • (c) 1 and 3 only
  • (d) 1, 2 and 3
Answer and explanation
(c) 1 and 3 only. Kant gives moral worth only to acts done from duty. Statement 2 describes Mill, not Bentham, who counted only quantity. Mill published The Subjection of Women in 1869.

Q2. Match List I (Thinker) with List II (Idea):

List IList II
A. Kant1. Hedonic calculus
B. Bentham2. Harm principle
C. J.S. Mill3. Categorical imperative
  • (a) A-1, B-3, C-2
  • (b) A-3, B-2, C-1
  • (c) A-2, B-1, C-3
  • (d) A-3, B-1, C-2
Answer and explanation
(d) A-3, B-1, C-2. The categorical imperative is Kant’s, the hedonic (felicific) calculus is Bentham’s, and the harm principle is Mill’s.

Q3. “Treat humanity, whether in your own person or in that of another, always as an end and never merely as a means.” This principle is the basis of which idea?

  • (a) Greatest happiness of the greatest number
  • (b) Human dignity
  • (c) Tyranny of the majority
  • (d) Survival of the fittest
Answer and explanation
(b) Human dignity. Kant’s humanity formulation holds that every rational person has dignity, not a price. Option (a) is Bentham’s principle, which a Kantian criticises for allowing individuals to be sacrificed for the total.

Q4. Which of the following is not one of the dimensions of Bentham’s hedonic calculus?

  • (a) Fecundity
  • (b) Propinquity
  • (c) Quality
  • (d) Extent
Answer and explanation
(c) Quality. Bentham’s seven dimensions are intensity, duration, certainty, propinquity, fecundity, purity and extent. Quality of pleasure is Mill’s addition.

Level 3: Mains Answer Writing

Q1. (60 words) What is Kant’s categorical imperative? How does it differ from a hypothetical imperative?

Model answer outline
  • Categorical imperative: an unconditional moral command binding on all rational beings, e.g. act only on a maxim you can will as a universal law; treat persons always as ends, never merely as means (Groundwork, 1785).
  • Hypothetical imperative: conditional on a desired goal (“if you want promotion, work hard”).
  • Example: “Do not take bribes” binds an officer whether or not he fears being caught.

Q2. (150–200 words) “Utilitarianism is a useful guide for public policy but a dangerous guide for individual rights.” Discuss with reference to Bentham and Mill.

Model answer outline
  • Intro: Bentham’s principle of utility judges acts and laws by the greatest happiness of the greatest number (Introduction to the Principles, 1789).
  • Useful for policy:
    1. Cost–benefit analysis of projects; outcome-based budgeting.
    2. Targeting welfare to maximise impact, e.g. focusing nutrition schemes on the most anaemic districts.
    3. Law reform and impartiality: each counts for one.
  • Dangerous for rights:
    1. The majority’s gain can justify sacrificing a minority, e.g. displacement of tribal families for a project.
    2. Ignores justice, motives and dignity; Bentham rejected natural rights.
  • Mill’s corrections: higher and lower pleasures; harm principle; protection of minorities and dissent; fear of the tyranny of the majority.
  • Balance: combine utility with Kantian dignity and constitutional rights (Arts 14, 19, 21). The land acquisition law of 2013, with social impact assessment, consent in specified cases and rehabilitation, is an example.
  • Chhattisgarh angle: mining and dam projects in Fifth Schedule areas need both aggregate benefit and Gram Sabha consent.
  • Conclusion: utility answers “how much good”, rights answer “at whose cost”; good policy needs both.

Key Takeaways

Key Takeaways
  1. Kant: morality is duty done for its own sake under the categorical imperative; persons are ends, never merely means.
  2. Bentham: the right act maximises total happiness, measured by a seven-dimension calculus; rights are creations of law.
  3. Mill: refined utilitarianism by quality of pleasure, and defended liberty through the harm principle.
  4. In Mains, use all three: virtue (character), duty (rights and rules), utility (outcomes), to reach balanced decisions.
