Utilitarianism

Utilitarianism holds that the right action is the one producing the greatest balance of well-being over suffering, counted impartially, with each person’s welfare weighed the same as any other’s. Jeremy Bentham set it out as a working principle of legislation in 1789, and it has done more to shape modern government than any rival moral theory: cost-benefit analysis, quality-adjusted life years in health rationing, and the entire apparatus of policy evaluation descend from it.

Conservatives have argued against it for two centuries without denying that consequences matter. Their objection is to the claim that consequences are all that matters, and to the confidence that a legislator can calculate them across a whole society. What the calculus omits — prescription, particular obligation, the moral weight of the person who cannot be traded against a larger number — is in the conservative account the substance of morality rather than sentimental residue.

Key Takeaways

• Bentham’s Introduction to the Principles of Morals and Legislation, printed in 1780 and first published in 1789, made the greatest-happiness principle a tool of legal reform.
• John Stuart Mill’s Utilitarianism, serialised in 1861 and published as a book in 1863, distinguished higher from lower pleasures to answer the charge of crudity.
• Conservatives object that aggregation permits sacrificing an individual whenever the sums favour it.
• Hayek’s knowledge argument holds that the information required for a social welfare calculation is dispersed and cannot be assembled centrally.
• Utilitarians answer with a reform record: penal reform, animal welfare, and the extension of moral standing beyond one’s own class and country.

History And Context

The theory’s ancestry runs through Epicurus and the eighteenth-century moralists. Francis Hutcheson wrote in 1725 of the action procuring the greatest happiness for the greatest numbers, and Cesare Beccaria applied a similar standard to criminal punishment in On Crimes and Punishments in 1764, a work Bentham read and admired.

Bentham gave it method. Printed in 1780 and first published in 1789, the Introduction to the Principles of Morals and Legislation opened by placing humanity under the governance of pain and pleasure, and by chapter four had set out a calculus with dimensions of intensity, duration, certainty, propinquity, fecundity, purity and extent.¹ The purpose was legislative: to replace judicial discretion and inherited penalty with a schedule of punishments proportioned to harm. Bentham applied the principle against the criminalisation of homosexual acts in an essay written around 1785 that he did not publish, and he extended moral consideration to animals on the ground that the question is not whether they reason but whether they suffer.

John Stuart Mill, raised by his father James on Benthamite lines and broken by it in a depressive crisis at twenty, rebuilt the doctrine. Utilitarianism appeared in Fraser’s Magazine in 1861 and as a book in 1863, arguing that pleasures differ in kind as well as quantity and that competent judges who have known both prefer the higher.² Henry Sidgwick’s The Methods of Ethics of 1874 gave the theory its most rigorous statement and conceded a dualism it could not resolve, between what reason requires impartially and what it requires of the agent’s own interest.

The twentieth century produced the sharpest reply. G. E. M. Anscombe coined the term “consequentialism” in a 1958 paper attacking the whole of modern moral philosophy, and argued that a theory permitting the judicial execution of an innocent man when the sums favour it has disqualified itself.³ Alasdair MacIntyre extended the critique in 1981, tracing the failure of Enlightenment ethics to its abandonment of the account of human purpose that gives moral terms their sense.⁴

The Conservative Position

The conservative objection has three parts.

The first concerns aggregation. Adding welfare across persons treats individuals as containers of a substance to be maximised, which licenses the sacrifice of one for many whenever the arithmetic works out. Rights function precisely to block that inference: they mark what remains off-limits regardless of the total. A theory that admits rights only as useful rules of thumb has admitted that it will discard them when the sums change, which is the moment at which they were needed.

The second concerns knowledge. Hayek’s argument against central planning applies with equal force here. The information required to compare welfare across millions of people exists nowhere in aggregated form, and the analyst who supplies the missing numbers is supplying his own judgement under a technical disguise.⁵ The apparent precision of the calculation conceals the choices buried in it.

The third concerns inheritance. Burke’s answer to the reformers of 1790 was that the individual reasoner’s stock of wisdom is small and that of the species, gathered in custom and prescription, is large. Utilitarian reform asks what a practice produces and, finding no measurable output, removes it. Conservatives reply that many practices — the marriage vow, the funeral, the oath, the presumption of innocence — do work that is not visible in the ledger until they are gone. Michael Oakeshott named this the rationalist error: treating practical knowledge as if it could be written down and audited.

Conservatives are not thereby indifferent to consequences. A prudential politics attends closely to results. The disagreement concerns whether results are the whole of the moral question, and whether the person adding them up knows what he thinks he knows.

Differing Positions

The utilitarian case is stronger than its critics allow, and its record is the argument. Bentham and his followers pressed for penal reform, prison inspection, the extension of the franchise, the legal standing of women, and animal welfare, at a time when the conservative defence of prescription was defending flogging, transportation and the slave trade’s residue. A theory that counts everyone equally, including the foreigner, the poor and the animal, corrected moral blind spots that inherited custom had preserved for centuries.

Rule utilitarians answer the objection about sacrificing the innocent directly: a rule permitting judicial murder produces worse consequences over time than a rule forbidding it, so the theory forbids it. Peter Singer’s work since 1975 shows the impartiality argument at full stretch, and its demands on the comfortable are considerably harsher than anything conservatism asks.

The honest conservative concession is that the calculus has won practically. Every health system rations, and rationing requires comparison. The conservative task is not to abolish the arithmetic but to keep it subordinate to the limits it cannot generate on its own.
