Study guide

What this lecture covers

This lecture introduces Jeremy Bentham's classical utilitarianism, the first of the three Enlightenment traditions the course examines in depth. Shapiro presents Bentham's famous opening claim that pleasure and pain govern everything humans do, then works through five defining features of his doctrine: it is comprehensive, naturalistic, egoistic-but-objective, radically consequentialist, and quantifiable.

Building on the course's earlier discussion of the workmanship ideal in Locke, this lecture shows a very different Enlightenment thinker who dispenses with theology altogether and instead grounds politics purely in a claimed science of human motivation. The lecture closes by asking why government is needed at all if everyone is already pursuing pleasure, introducing the idea that individual and social interests can diverge.

Key ideas

  • Principle of utility: Bentham's claim that pleasure and pain are the "two sovereign masters" governing all human behavior, and that institutions should be designed to maximize the greatest happiness of the greatest number.
  • Comprehensive and deterministic: Bentham holds that even apparently altruistic acts (running into a fire, sacrificing for a child) reduce to pleasure-seeking and pain-avoidance.
  • Objective egoism: people act self-interestedly, but Bentham claims this is true regardless of what people themselves believe motivates them — their own understanding is often wrong.
  • Radical consequentialism: only outcomes matter, not intentions; this contrasts with the deontological tradition (Kant, later Rawls and Nozick) that the course will cover afterward.
  • Quantifiability: Bentham treats utility as measurable along dimensions of intensity, duration, certainty, and nearness in time, and believes interpersonal comparisons of utility are possible.
  • Nozick's experience machine: a thought experiment (introduced ahead of its later use in critiquing utilitarianism) asking whether people would choose a machine that guarantees pleasurable experience, testing whether autonomy matters beyond pleasure itself.
  • Market failure and public goods: government is needed because individually rational choices (free-riding on national defense, overgrazing a commons) can produce socially harmful outcomes even under Bentham's framework.

Walkthrough

Bentham's principle of utility (0:00)

Shapiro introduces Bentham as a thinker who pushes one idea to its logical extreme, useful precisely because he reveals both the appeal and the limits of utilitarianism. He reads Bentham's opening paragraph from Principles of Morals and Legislation, in which pain and pleasure are described as the "sovereign masters" of human conduct, and explains that Bentham rejects appeals to tradition, religion, and natural law in favor of a purely scientific account of politics.

Five features of Bentham's system (8:24)

Through class discussion and counterexamples (running into a fire, sacrificing for one's child), Shapiro tests Bentham's claim that all behavior reduces to pleasure-seeking and pain-avoidance. He then lays out the doctrine's remaining features: it is naturalistic (grounded in survival, pre-dating Darwin), egoistic but not subjectivist (self-interest is objectively true even if people deny it), radically consequentialist (results matter, not intentions), and quantifiable (utility can in principle be measured and compared across people). The Nozick "experience machine" thought experiment is used to probe whether people value something beyond pleasure itself, such as autonomy.

Individual versus social utility and the role of government (32:46)

Shapiro asks why government would be needed at all if utility maximization is inevitable, and introduces the idea that individually rational behavior does not always add up to a socially optimal result. He discusses free-riding on public goods, such as taxation for a war effort, and the "tragedy of the commons" problem of shared grazing land, as cases where government coercion becomes necessary to align individual incentives with the collective good.

Before you watch

  • Review Lecture 3 on Locke's workmanship ideal, since Shapiro's discussion of "science" versus theology in this lecture builds on that contrast.
  • Recall the five traditions previewed in Lectures 1 and 2, since utilitarianism is the first one covered in depth.

Moral Foundations of Politics (PLSC 118)

Jeremy Bentham's formulation of classical utilitarianism is the first Enlightenment tradition that the course will cover in depth. In his Principles of Morals and Legislation, Bentham outlines the principle of utility; that is, the principle that all men are pleasure-seeking and pain-avoiding. Professor Shapiro presents the case that classical utilitarianism has five characteristics: (1) it is comprehensive and deterministic, (2) it is a pre-Darwinian naturalist doctrine, (3) it is egoistic but not subjectivist, (4) it is highly consequentialist, and (5) it is based on the idea that utility is quantifiable and that one can make interpersonal comparisons of utility. As for the role of government, Bentham believes that it is to "maximize the greatest happiness of the greatest number." The class discusses the merits of utilitarianism through examination of Robert Nozick's hypothetical experience machines, the implication of public goods, and "the tragedy of the commons."
