What is the right thing to do when every option costs lives? In the opening sessions of Harvard\u2019s Justice<\/strong> course, Michael Sandel uses a runaway trolley, a bridge, a hospital, and a 19th-century shipwreck to show how ordinary moral instincts collide\u2014and why the clash between consequentialist<\/strong> and categorical<\/strong> reasoning has shaped law, politics, and philosophy for centuries.<\/p>\n\n\n\n

The Classic Trolley Problem: Five Lives vs. One<\/h2>\n\n\n\n

Sandel begins with a scenario: you are driving a trolley at 60 mph. Five workers are on the track ahead. The brakes fail. You cannot stop.<\/p>\n\n\n\n

Then you notice a side track with one worker<\/strong> on it. You can turn the steering wheel, killing one person but sparing five.<\/p>\n\n\n\n

When Sandel polls his audience in Sanders Theatre, the vast majority<\/strong> say they would turn onto the side track.<\/p>\n\n\n\n

The most common reason: It can\u2019t be right to kill five when you could kill one instead.<\/em> One student compares it to the passengers on United Flight 93 on 9\/11\u2014tragic, but better to sacrifice fewer lives to save more.<\/p>\n\n\n\n

Those who would not<\/strong> turn offer a very different warning. One student argues that \u201cbetter to kill one to save five\u201d is the same logic that can justify genocide and totalitarianism<\/strong>\u2014sacrificing one group to preserve another. When pressed, she says she would still go straight and kill the five rather than adopt that principle.<\/p>\n\n\n\n

The \u201cFat Man\u201d Variant: Why Most People Change Their Answer<\/h2>\n\n\n\n

Sandel then changes the setup. You are an onlooker on a bridge\u2014not the driver. A runaway trolley is heading toward five workers. Next to you stands a very large man. If you push him onto the track, he dies, but the trolley stops and the five survive.<\/p>\n\n\n\n

This time, most people would not push<\/strong>.<\/p>\n\n\n\n

That raises the central puzzle: what happened to the principle that one death is better than five?<\/p>\n\n\n\n

Students offer competing explanations:<\/p>\n\n\n\n

    \n
  • Active vs. passive involvement<\/strong>\u00a0\u2014 pushing someone who was not already in danger feels like choosing to involve an innocent third party<\/li>\n\n\n\n
  • Direct killing vs. redirecting harm<\/strong>\u00a0\u2014 steering a runaway vehicle feels different from using your hands to kill someone<\/li>\n\n\n\n
  • Becoming involved as a bystander<\/strong>\u00a0\u2014 in the first case, the driver is already part of the crisis; on the bridge, you can choose whether to enter it at all<\/li>\n<\/ul>\n\n\n\n

    When Sandel asks whether opening a trap door under the man\u2014via a steering wheel rather than a push\u2014would feel different, student Andrew still hesitates. Even indirect mechanisms can feel morally worse than turning the trolley in the original case.<\/p>\n\n\n\n

    Doctor Dilemmas: Triage and the Transplant Surgeon<\/h2>\n\n\n\n

    Sandel moves the same logic into medicine.<\/p>\n\n\n\n

    Emergency room triage<\/h3>\n\n\n\n

    Six patients arrive from a trolley wreck. Five have moderate injuries; one is severely injured. You can spend all day saving the one\u2014and the five die\u2014or treat the five and let the one die.<\/p>\n\n\n\n

    Almost everyone saves the five<\/strong>, using the same one-vs.-five calculus.<\/p>\n\n\n\n

    The transplant surgeon<\/h3>\n\n\n\n

    Now you are a transplant surgeon. Five patients need a heart, lung, kidney, liver, and pancreas. No donors are available. In the next room, a healthy man is napping after a checkup. You could quietly remove his organs, killing him but saving five.<\/p>\n\n\n\n

    Almost no one<\/strong> would do it.<\/p>\n\n\n\n

    One student in the balcony tries to dodge the dilemma by suggesting harvesting organs from whichever of the five dying patients expires first\u2014a clever workaround Sandel calls \u201ca great idea\u201d that \u201cwrecked the philosophical point.\u201d<\/p>\n\n\n\n

    The pattern is clear: when consequences alone seem to govern our choices in some cases, the character of the act itself<\/strong> stops us in others.<\/p>\n\n\n\n

    Consequentialist vs. Categorical Moral Reasoning<\/h2>\n\n\n\n

    From these debates, two frameworks emerge.<\/p>\n\n\n

    \n\n
    Framework<\/th>Core idea<\/th>Example in the lectures<\/th><\/tr><\/thead>
    Consequentialist<\/strong><\/td>Morality depends on the results<\/strong> of an act\u2014the state of the world it produces<\/td>Turn the trolley; save five at the cost of one<\/td><\/tr>
    Categorical<\/strong><\/td>Some acts are wrong in themselves<\/strong>, regardless of outcomes<\/td>Do not push the innocent man; do not harvest organs from a healthy patient<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<\/div>\n\n\n

    The leading consequentialist tradition is utilitarianism<\/strong>, associated with 18th-century English philosopher Jeremy Bentham<\/strong>. The leading categorical tradition is associated with German philosopher Immanuel Kant<\/strong>.<\/p>\n\n\n\n

    Sandel previews the semester\u2019s reading list\u2014Aristotle, John Locke, Kant, John Stuart Mill\u2014and contemporary debates on equality, affirmative action, free speech, same-sex marriage, and military conscription. The goal is not abstract trivia but understanding what is at stake in everyday political life.<\/p>\n\n\n\n

    Why Philosophy Is Unsettling\u2014and Unavoidable<\/h2>\n\n\n\n

    Sandel warns that studying justice carries personal and political risks<\/strong>.<\/p>\n\n\n\n

    Philosophy does not mainly supply new facts. It takes what we already believe in familiar settings and makes it strange<\/strong>. Once the familiar turns strange, it cannot fully return to innocence.<\/p>\n\n\n\n

    Politically, philosophy may even make you a worse citizen before a better one<\/strong>\u2014because it distances you from conventions and settled assumptions. In Plato\u2019s Gorgias<\/em>, Callicles tells Socrates to quit arguing and \u201cgo to business school\u201d\u2014meaning: stop questioning and pursue reputation and success.<\/p>\n\n\n\n

    The characteristic evasion is skepticism<\/strong>: if Aristotle, Locke, Kant, and Mill never settled these questions, why should we?<\/p>\n\n\n\n

    Sandel\u2019s reply: the questions persist because we live some answer to them every day<\/strong>. Kant wrote that skepticism is a resting place for reason, not a permanent home. The course aims to awaken \u201cthe restlessness of reason.\u201d<\/p>\n\n\n\n

    Jeremy Bentham and Utilitarianism: \u201cThe Greatest Good for the Greatest Number\u201d<\/h2>\n\n\n\n

    In the next lecture, Sandel tests utilitarianism against a real case\u2014not a hypothetical.<\/p>\n\n\n\n

    Bentham\u2019s core claim: the right action maximizes utility<\/strong>\u2014the balance of pleasure over pain, happiness over suffering. Humans are governed by two \u201csovereign masters\u201d: pain and pleasure. Morality, law, and policy should maximize overall happiness.<\/p>\n\n\n\n

    The slogan: \u201cThe greatest good for the greatest number.\u201d<\/strong><\/p>\n\n\n\n

    Queen v. Dudley and Stephens: Cannibalism at Sea<\/h2>\n\n\n\n

    The 1884 British case Queen v. Dudley and Stephens<\/em> is a staple of law schools worldwide.<\/p>\n\n\n\n

    After the yacht Mignonette<\/em> sank in the South Atlantic, four crew members escaped in a lifeboat: Captain Thomas Dudley<\/strong>, First Mate Edwin Stephens<\/strong>, sailor Brooks<\/strong>, and 17-year-old cabin boy Richard Parker<\/strong>\u2014an orphan on his first long voyage.<\/p>\n\n\n\n

    They had two cans of turnips, a turtle, and then nothing for eight days<\/strong>. Parker drank seawater, grew ill, and appeared near death.<\/p>\n\n\n\n

    On day 19, Dudley proposed drawing lots to decide who would die. Brooks refused. No lottery was held.<\/p>\n\n\n\n

    The next day, Dudley told Brooks to look away, signaled Stephens, said a prayer, told Parker his time had come, and killed him with a penknife. All three survivors ate Parker\u2019s body for four days until rescue on day 24.<\/p>\n\n\n\n

    Dudley\u2019s diary entry on rescue day: \u201cOn the 24th day, as we were having our breakfast\u2026 a ship appeared at last.\u201d<\/em><\/p>\n\n\n\n

    Back in England, Brooks turned state\u2019s witness. Dudley and Stephens stood trial. They did not deny the facts. Their defense: necessity<\/strong>\u2014better one should die so three could live. The prosecutor replied: murder is murder.<\/p>\n\n\n\n

    How the Class Judged Dudley and Stephens<\/h2>\n\n\n\n

    When Sandel asks students to judge the act morally\u2014not legally\u2014a sizable majority<\/strong> say what Dudley and Stephens did was wrong. Roughly 20%<\/strong>, led by a student named Marcus, defend them.<\/p>\n\n\n\n
