Lecture 2: Putting a Price Tag on Life

What this lecture covers

Building on the trolley and cabin-boy cases from the previous lecture, this session examines Jeremy Bentham's utilitarianism in practice, through real cost-benefit analyses that place a dollar value on human life, and then turns to John Stuart Mill's attempt to defend utilitarianism against its critics.

After watching, you can state Bentham's principle of utility in your own words, explain two standard objections to utilitarianism (minority rights and the commensurability of values), and describe Mill's proposed test for distinguishing higher from lower pleasures.

Key ideas

• Principle of utility: Bentham's claim that the right action, for individuals and legislators alike, is the one that maximizes the balance of pleasure over pain.
• Cost-benefit analysis: the modern, everyday application of utilitarian logic, used by companies and governments to weigh policies in monetary terms.
• The value-of-life objection: assigning a dollar figure to a human life, as in the Ford Pinto case, can produce results that feel morally repugnant even when the arithmetic is consistent.
• The minority-rights objection: aggregating preferences for "the greatest good for the greatest number" can run over the rights or interests of a minority.
• Commensurability of values: utilitarianism assumes all goods can be measured on a single scale, an assumption Sandel probes with Edward Thorndike's 1930s survey of what people would pay to avoid unpleasant experiences.
• Higher versus lower pleasures: Mill's attempt to show that utilitarianism can rank pleasures qualitatively, not just by intensity and duration.
• Mill's test: a pleasure is higher if people who have experienced both it and a lower alternative consistently prefer it.

Walkthrough

Bentham's utility principle and cost-benefit analysis (0:03)

Sandel recaps Bentham's core idea: morality means maximizing the collective balance of pleasure over pain, summed across everyone affected. He introduces cost-benefit analysis as this logic applied by governments and firms, then presents a real study Philip Morris commissioned in the Czech Republic showing a net public-finance "gain" from smoking due to reduced pension and healthcare costs from early deaths.

The Ford Pinto case (6:17)

Sandel walks through the well-known Ford Pinto lawsuit, in which internal documents showed Ford had calculated that fixing a dangerous fuel-tank defect would cost more than paying for the deaths and injuries it would cause, valuing each death at roughly $200,000. Students debate whether the flaw was assigning too low a number, or whether any dollar figure on a life is illegitimate, extending the discussion to cell-phone-related driving deaths.

Objections to utilitarianism (15:30)

The class raises two broad objections. First, utilitarianism may fail to respect the rights of a minority, since aggregating preferences can justify severe harm to a few if it produces enough happiness for the many; Sandel sharpens this with the example of Christians thrown to lions for Roman entertainment. Second, he questions whether all values can be reduced to a single measure, illustrating this with Thorndike's survey asking Depression-era subjects what payment would compensate them for pulling a tooth, eating a worm, or living in Kansas.

Mill's defense and higher pleasures (33:58)

Sandel introduces John Stuart Mill, a child prodigy raised by his utilitarian father, who tried to humanize Bentham's theory. Mill insists utility remains the sole standard of morality but argues a utilitarian can still distinguish higher from lower pleasures: a pleasure is higher if people who have experienced both prefer it, without any external moral standard imposed on them.

Testing Mill's claim with Shakespeare and the Simpsons (38:06)

Sandel runs a live experiment, playing clips of a Hamlet soliloquy, the reality show Fear Factor, and The Simpsons, then polling which students enjoyed most and which they considered the worthiest experience. Most prefer watching The Simpsons yet still rank Shakespeare as higher, a split that becomes the class's test case for whether Mill's preference-based account of higher pleasures actually works, or whether it smuggles in a standard of worth that goes beyond mere preference.

Before you watch

• Watch Lecture 1 first, since this session assumes you already know the distinction between consequentialist and categorical moral reasoning.
• Keep Bentham's basic formula, maximizing pleasure over pain, in mind before the cost-benefit examples begin.

Check your understanding

1. What made the Philip Morris and Ford Pinto cost-benefit analyses controversial from a utilitarian standpoint?
2. How does the objection about minority rights challenge the idea of "the greatest good for the greatest number"?
3. What did Thorndike's survey suggest about whether all values can be measured on one scale?
4. According to Mill, what makes a pleasure "higher" rather than merely more intense or longer-lasting?
5. Why does the Shakespeare-versus-Simpsons experiment create a problem for Mill's test?
