1748-1832 CE
Right and wrong can be measured objectively: the best action is whatever produces the greatest happiness for the greatest number of people. All human behaviour is ultimately driven by seeking pleasure and avoiding pain. Morality becomes a calculation — weigh up the pleasures and pains an action will cause for everyone affected, and choose accordingly.
Jeremy Bentham was born February 15, 1748, in London (some sources say Houndsditch, others Red Lion Street), into wealthy attorney family. His father Jeremiah Bentham was successful lawyer; mother Alicia Grove died when Jeremy was eleven. His younger brother Samuel became naval architect and engineer.
He was child prodigy. Reading serious history at age three, studying Latin at four, entered Queen’s College, Oxford at age twelve (1760). He found Oxford education backward, emphasizing classical languages over practical knowledge. He received BA (1763) and MA (1766). His father pushed him toward legal career, and Jeremy studied law at Lincoln’s Inn, called to bar (1769).
But he never practiced law. Instead, he devoted life to analyzing and reforming legal systems philosophically. His legal training revealed English law’s irrationalities, complexities, and injustices. He resolved to create rational, systematic legal code based on scientific principles.
His intellectual breakthrough came through reading Hume, Helvétius, and Beccaria. Hume’s empiricism, Helvétius’s hedonism, and Beccaria’s penal reform influenced his developing utilitarianism. He embraced psychological hedonism: humans are governed by pleasure and pain, seeking former, avoiding latter. From this he derived moral principle: right action maximizes pleasure and minimizes pain for all affected.
He published Fragment on Government (1776) anonymously, criticizing Blackstone’s Commentaries on English law. Blackstone defended existing common law through natural law theory. Bentham attacked this as mystification — appeals to natural law, social contract, and inalienable rights were “nonsense upon stilts,” masking vested interests in maintaining status quo. True basis of law should be utility — promoting greatest happiness.
His major systematic work was Introduction to the Principles of Morals and Legislation, written 1780s, published 1789. This presented utilitarianism comprehensively: Nature has placed mankind under governance of two sovereign masters, pain and pleasure. Utility principle approves/disapproves actions according to tendency to augment or diminish happiness. Felicific calculus enables calculating pleasures/pains through seven dimensions: intensity, duration, certainty, propinquity, fecundity, purity, extent.
He applied utilitarianism systematically to law, punishment, and government. Punishment is justified only if preventing greater harm — not for retribution, but for deterrence and reform. He proposed rational punishment scheme proportioning penalties to crimes according to utility.
His most famous project was Panopticon (1787) — revolutionary prison design. Circular building with central observation tower allowing single watchman to observe all prisoners (in cells around perimeter) without prisoners knowing when observed. Bentham believed this would reform prisoners through constant potential surveillance creating self-discipline. He spent years and fortune trying to build it (Britain never did, though concept influenced later prison designs and Foucault’s theories about surveillance society).
He became leading philosophical radical — advocating democratic reform, universal suffrage (including women, shocking for era), secret ballot, annual parliaments, abolition of monarchy and House of Lords. He founded Westminster Review (1824) as vehicle for radical ideas.
His utilitarian reforms extended to: Animal rights — since animals feel pain, they have moral status. “The question is not, Can they reason? nor, Can they talk? but, Can they suffer?” This pioneered modern animal ethics. Sexual ethics — decriminalized homosexuality, arguing consensual acts harming no one shouldn’t be illegal. Women’s rights — advocated political equality, though views were complex and inconsistent. Education — proposed rational, secular education teaching useful knowledge, not classics. Economics — influenced by Adam Smith, supported free markets as promoting utility, but justified government intervention preventing harm.
Personally, he lived eccentric, reclusive life. Never married, though had close platonic relationship with several women. His closest intellectual companion was James Mill (utilitarian philosopher and historian), whose son John Stuart Mill became Bentham’s intellectual heir and successor.
He worked obsessively, writing millions of words — most unpublished during lifetime. His writing style was complex, full of neologisms (he invented “international,” “maximize,” “minimize,” “codification”). He created elaborate classification systems for everything. His manuscripts filled boxes (many edited posthumously).
Strange habits: He called himself “hermit of Queen Square Place” (his London residence). He wore unusual old-fashioned clothes. He exercised by running in his garden, which he called “vibrating.” He named his walking stick “Dapple” and his teapot “Dick.” These eccentricities combined with radical ideas made him seem bizarre to contemporaries.
In old age, he remained intellectually active. He corresponded with reformers worldwide, advised newly independent South American countries on constitutions, and continued writing. He founded University College London (1826) as secular alternative to Oxford/Cambridge, allowing dissenters and women.
He died June 6, 1832, age 84. His will specified body’s dissection for anatomical study (promoting medical science), with skeleton preserved as “Auto-Icon” — dressed in his clothes, topped with wax head (original mummified head preserved separately after attempt failed), displayed at University College London. He intended this as statement against superstitious attitudes toward dead bodies and to serve utilitarian function (teaching anatomy, promoting institution).
The Auto-Icon remains displayed at UCL today, supposedly attending board meetings (recorded as “present but not voting”). Whether apocryphal, this captures Bentham’s eccentric utilitarianism — even his corpse serves useful purpose.
His influence was immense: He founded systematic utilitarianism influencing moral philosophy profoundly. He inspired legal positivism (law as human creation, not natural law). He pioneered legal reform movements worldwide. He influenced economic theory (welfare economics, cost-benefit analysis). He shaped prison reform, animal rights, women’s rights, democratic reform. His disciples (James Mill, John Stuart Mill, Edwin Chadwick) spread utilitarian ideas through 19th century. His weaknesses — crude hedonism, dismissal of rights, faith in calculation — provoked responses refining utilitarianism (Mill’s qualitative hedonism) and developing alternatives (Kant’s deontology revival, virtue ethics).
For better and worse, his vision of rational, scientific reform based on measurable happiness shaped modernity. We live in cost-benefit world Bentham pioneered.
"Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do."
— Introduction to the Principles of Morals and Legislation, Chapter 1 — foundational statement of psychological and ethical hedonism
"The question is not, Can they reason? nor, Can they talk? but, Can they suffer?"
— Introduction to the Principles of Morals and Legislation, Chapter 17 — pioneering argument for animal rights based on sentience
"Natural rights is simple nonsense: natural and imprescriptible rights, rhetorical nonsense—nonsense upon stilts."
— Anarchical Fallacies (critique of French Declaration of Rights) — rejecting natural rights theory
Bentham founded systematic utilitarianism by establishing pleasure and pain as sole values and proposing felicific calculus for moral decision-making.
Psychological Hedonism: Foundation of his ethics: Nature placed mankind under two sovereign masters — pain and pleasure. Humans seek pleasure, avoid pain. This is descriptive claim about human psychology, not moral prescription. We’re constituted to pursue pleasure; this is fact about human nature.
Ethical Hedonism: From psychological hedonism derives ethical principle: pleasure is sole intrinsic good, pain sole intrinsic evil. Everything else (wealth, knowledge, friendship) is instrumentally valuable — good only as means to pleasure. Hedonism is monistic — only one ultimate value, pleasure (understood as happiness, satisfaction, well-being).
Utility Principle: Right actions promote happiness (pleasure), wrong actions produce reverse (pain). For individual, right action maximizes own pleasure. For community (sum of individuals), right action maximizes total pleasure. This is greatest happiness principle: “greatest happiness of greatest number.”
Impartiality: Each person’s pleasure counts equally — “each to count for one, nobody for more than one.” No inherent hierarchy. King’s pleasure equals pauper’s pleasure of equal intensity. This democratic hedonism scandalized elites but grounded moral equality.
Felicific Calculus: How to measure happiness? Bentham proposed calculation considering seven dimensions: Intensity: How strong is pleasure/pain? Duration: How long does it last? Certainty: How probable is it? Propinquity: How soon will it occur? Fecundity: Will it produce more pleasures? Purity: Is it unmixed with pain? Extent: How many people are affected?
Calculate each dimension for all affected parties, sum total pleasure/pain, choose action maximizing net pleasure. This makes ethics scientific, calculable, objective.
Pushpin and Poetry: Famous claim: “Quantity of pleasure being equal, pushpin is as good as poetry.” Pushpin was simple game; poetry was high culture. Point: No inherent hierarchy among pleasures. If pushpin produces equal pleasure, it’s equally valuable. This offended elitists but consistently applied democratic hedonism.
John Stuart Mill later rejected this, distinguishing higher (intellectual, moral) and lower (bodily, sensual) pleasures. But Bentham maintained quantity alone matters — qualitative distinctions introduce subjective bias.
Legal Theory: Bentham applied utilitarianism to law systematically: Law is command of sovereign, not natural law or divine law (legal positivism). Law’s purpose is maximizing utility — promoting happiness, preventing harm. Laws should be judged by consequences, not origins, precedents, or metaphysical principles. Criminal law justified only if preventing greater harm. Punishment justified through: Deterrence — preventing future crimes by threat. Reform — changing offender’s behavior. Incapacitation — preventing offender from reoffending.
Not retribution — punishment for its own sake is adding pain without benefit, violating utility. Punishment should be proportioned to crime according to utility calculus — severe enough to deter, not excessive.
Rights: Controversial view: Natural rights are “nonsense upon stilts.” Rights aren’t pre-political natural endowments but legal creations justified by utility. Saying someone has right means law should protect their interest because doing so promotes utility. Rights are instruments for happiness maximization, not foundations.
This opposed social contract tradition (Locke, Rousseau) and natural rights declarations (American, French). But Bentham wasn’t rejecting rights — he argued they require utilitarian justification, not metaphysical grounding.
Animal Ethics: Revolutionary extension: Animals feel pain, therefore have moral status. “The question is not, Can they reason? nor, Can they talk? but, Can they suffer?” This pioneered modern animal ethics. If only pleasure/pain matter morally, and animals experience pain, then animals’ suffering counts in utility calculations. This justified legal protections against cruelty.
Problems and Criticisms: Measurement: Can happiness be quantified? Felicific calculus assumes pleasures/pains are measurable and comparable. But subjective experiences resist precise measurement. How compare intense brief pleasure with mild lasting pleasure?
Impartiality: Should I care equally about stranger’s pleasure and loved one’s? Common morality gives special weight to family, friends. Bentham’s impartiality seems alienating.
Rights: Does utility justify violating individuals for greater good? Classic objection: Utility might justify punishing innocent person to prevent riot (deterrence), or harvesting organs from one to save five. Bentham’s dismissal of rights seems to permit injustice.
Quality: Are all pleasures equal? Many find intellectual pleasures more valuable than simple pleasures, even if less intense. Pushpin-poetry equivalence seems philistine.
Demandingness: Utilitarianism seems to require constantly maximizing utility — every choice should benefit greatest number. This is psychologically exhausting and morally overwhelming.
Bentham’s Responses: He acknowledged calculation difficulties but insisted utility remains right criterion even if imperfectly applied. He distinguished act-utilitarianism (each act judged by utility) from rule-utilitarianism (follow rules generally promoting utility). He believed rules prevent sacrificing innocents — rule against punishing innocents promotes utility long-term. He maintained qualitative distinctions introduce subjective bias — quantity is objective. He argued morality requires impartiality — partiality is permissible when promoting greater utility long-term (caring for family generally does).
