On a gray Sunday morning in February 2012, T.M. Scanlon (b. June 28, 1940) climbs the steps to Emerson Hall and finds the philosophy department overrun. Young men in ill-fitting suits pace the corridors, muttering arguments to themselves, checking their notes. He scans the hallway with a look of irritation. Then he sees what has happened. A debate tournament has taken the building for the weekend. His laugh comes loud and rolls up the stairwell. These would-be Sophists have it backward, he tells the writer who has come to interview him. They spend their talent scoring points off one another. They ought to turn it on their own beliefs instead.
He is tall and lanky, in his early seventies, with a long face and large hands. To his colleagues and students he is not T.M. He is Tim. He leads the way to a third-floor office and a long table at the back, and they talk into the afternoon while the light fails over Harvard Yard. Above them hangs a reproduction of Ambrogio Lorenzetti’s fresco of good government in Siena, its painted citizens going about a well-ordered common life.
The setting fits the man. Scanlon has spent his career on one question. What do we owe to each other? His answer built one of the ruling theories of modern ethics. An act is wrong, he holds, if it would be ruled out by principles that no one could reasonably reject as a basis for informed, unforced agreement among equals. Morality, on this account, is the work of justifying ourselves to one another. Right and wrong track what free and equal people could defend to each other across a table. He set that idea against the utilitarian tradition of Bentham and Mill, which measures the good by its sum, and against the Kantian tradition of duty.
He grew up in Indianapolis. His father came from an Irish immigrant family, the first generation to get an education, and put himself through college on the money from a large paper route. He became a lawyer, a successful litigator, and he loved the American constitutional order. Much of the talk at the family dinner table ran to constitutional questions. Scanlon’s mother had gone to college and studied some philosophy before she married and kept the home, as most women of her generation did. Both parents were sharp. Both pushed their son to go East for school.
He went to an enormous public high school, close to two thousand students, and loved it for its variety, a small city of a place where a student could pick among three or four versions of the same class and among teachers known to be hard or easy. He came for the mathematics. The school had strong math teachers, and he meant to major in the subject.
At Princeton the plan held for a while. He took his mathematics and drifted toward philosophy, which his parents had mentioned as something he might enjoy. He wrote his senior thesis on the philosophy of mathematics under Paul Benacerraf, who told him he should apply to graduate school. The suggestion flattered him and frightened him. It sat so far outside anything he had pictured for himself that he could hardly work up the nerve. He applied, got in, and then could not make the jump. He signed up instead for Harvard Law School. At the last minute an alternate Fulbright came through, and he left for Oxford.
At Oxford he worked mostly with Michael Dummett (1925–2011), whose rigor left a mark, and there the thing settled in him. He had taken some moral and political philosophy as a senior and thought it terrific. Now he decided he could not give it up. He returned to the United States and entered the doctoral program at Harvard, wrote a dissertation in mathematical logic under Burton Dreben (1927–1999), and finished in 1968. He was good at logic. He learned its techniques fast. But he judged himself to have no originality in it, no instinct for the next thing worth proving. In moral and political philosophy the ideas came.
His first teacher in political philosophy had been the classicist Gregory Vlastos (1907–1991), who taught him as a senior at Princeton. At the end of the term Vlastos invited a friend down to give a talk, a former junior colleague from Cornell named John Rawls (1921–2002), and told the class to come. Rawls read a paper called “Justice as Reciprocity,” a reworking of his earlier “Justice as Fairness.” Scanlon sat in the audience. He had read the earlier paper in class and thought it good, though as a beginner he did not yet know how to tell good from great. What struck him was the regard his teachers held for the speaker. He did not yet sense that this man would remake the field. He met Rawls properly at Harvard, as a graduate student, in the fall of 1963, and came to stand in awe of him. Rawls proved modest and welcoming, and the two became friends.
Scanlon left Harvard in 1966 for a teaching post at Princeton, where he had been an undergraduate, and completed his doctorate there two years later. He stayed eighteen years. He kept publishing a little logic, then let it go without ceremony, never announcing the change even to himself. His first notable papers took up freedom of expression, a straight line back to those constitutional arguments at his father’s table.
In 1972 he published “A Theory of Freedom of Expression” and set out what came to be called the Millian Principle. Government may not suppress speech, he argued, merely because listeners might form harmful beliefs from it or later act on those beliefs. People are to be treated as capable of weighing arguments for themselves. Seven years later, in “Freedom of Expression and Categories of Expression,” he pulled back. The first version could not handle deceptive advertising or incitement, speech that does harm apart from persuading anyone of anything. He kept the commitment and built a more careful account, one that weighed the interests of speakers, of listeners, and of bystanders. Constitutional lawyers still teach both papers.
The center of his intellectual life for three decades was a discussion group. It met once a month, in New York and in Cambridge, and never grew past ten or twelve people. The roster reads like a census of a generation of American moral and political philosophy: Thomas Nagel (b. 1937), Ronald Dworkin (1931–2013), Robert Nozick (1938–2002), Marshall Cohen, Owen Fiss, Charles Fried, Michael Walzer, and later Judith Jarvis Thomson, Susan Wolf, Frances Kamm, Michael Sandel, Christine Korsgaard. Rawls belonged too. Someone circulated a paper in advance. They ate lunch and gossiped for an hour, then argued hard from half past one until half past five. Getting a word in took effort. They debated whether to appoint a chair to call on people, the talk ran so hot. Scanlon later called the group the most important thing in his development, a standing seminar with a gang of great teachers.
One year in the mid-1970s the philosopher G.A. Cohen (1941–2009) visited Princeton, and the two rode a bus to New York together for a meeting of the group. Cohen was then a Marxist at work on his defense of Karl Marx’s theory of history. On the ride they argued about Rawls and Nozick. Cohen, to Scanlon’s surprise, found Nozick’s approach the more appealing, drawn to its focus on the individual rather than on institutions. Scanlon pressed him. Surely a Marxist, of all people, held that the structures mattered more than personal virtue. Cohen kept answering that Nozick’s way just seemed right to him. Scanlon put it down to something in Cohen’s upbringing.
In 1984 Rawls came down to Princeton. He said he wanted to talk over some questions the two had been working on. What he wanted was to offer Scanlon a job at Harvard. Scanlon found the gesture moving. He found the leaving hard. His closest friends were at Princeton and the place held him, though by then he felt himself a little to the side of its center of gravity. He took the chair, the Alford Professorship of Natural Religion, Moral Philosophy, and Civil Polity, among the oldest endowed seats in American philosophy, and he returned to the building where he had once been a student.
The turn that made his name had begun a few years earlier, and Rawls had planted it with a single sentence. Scanlon had written a paper arguing that rights are principles we accept because they protect important values at acceptable cost, and he had cast the whole argument in consequentialist terms. He showed it to Rawls. Rawls, in his quiet and hesitant way, said the argument seemed right to him, but that he did not see why Scanlon called it consequentialism. Scanlon took the remark and sat with it. Around 1979 he saw the frame he had been missing. He could keep all the arguments and drop the consequentialism. He could ground morality in what people can justify to one another.
That frame became What We Owe to Each Other, published in 1998, the book on which his reputation rests. Contractualism, in his hands, is a theory of the morality we owe one another as rational creatures, not a theory of where governments come from. It does not run in the line of Hobbes, Locke, and Rousseau, who used a contract to explain political authority. It asks a narrower and more personal question. Could the principle under which you propose to act be rejected, for good reason, by someone it burdens? If so, acting on it wrongs that person. The test runs person by person. It does not add up gains and losses across a population and call the largest sum right. Each individual holds a standing to refuse that no aggregate can override. Here Scanlon parts from the utilitarians, from Jeremy Bentham to Peter Singer (b. 1946), for whom the moral goal is the greatest total welfare.
He owes much to Kant and takes pains to mark the distance. He shares Kant’s respect for persons. He declines to rest morality on the Kantian apparatus of autonomy and universal law. Obligation, for Scanlon, grows out of a simpler human wish, the wish to be able to justify how you live to the people who have to live with you. Guilt, on this view, marks damage to that standing between persons, not the breach of a rule written somewhere above them.
His work and Rawls’s fit together like two halves. Rawls asked what principles should govern the basic structure of a society, and answered with the original position and the veil of ignorance. Scanlon asked what individuals owe each other apart from any political order. Between them they set much of the agenda for English-language political philosophy after the appearance of A Theory of Justice in 1971.
The reach extended past that one book. In metaethics he offered the buck-passing account of value. Philosophers had long treated goodness as a property that in itself gives us reason to want a thing. Scanlon turned it around. A thing is not good and therefore reason-giving. It is good because it already has features that give us reason to admire it, to choose it, to protect it. Goodness adds no further push of its own. The inversion looks small and has occupied metaethicists ever since.
In Moral Dimensions (2008) he pulled apart three questions that moralists tend to run together. Whether an act is permissible is one question. What the act says about the person’s regard for others is a second. Whether blame fits is a third. Blame, for Scanlon, is a change in a relationship. To blame a man is to judge that what he has done has damaged your standing with him, and on that basis to revise how you mean to treat him, whether to trust him, to count on him, to keep him as a friend. Some philosophers fault the account for leaving too little room for the heat of moral anger.
Within the same work he drew a distinction that has traveled into law and policy. Attributional responsibility asks whether an act reflects a person’s own judgment and character, so that praise or blame attaches. Substantive responsibility asks what claims people have on one another for the costs and outcomes of their choices. A man can be fully answerable for a bad decision and still hold a claim on others for basic help. Debates over welfare and desert have leaned on the split.
In Being Realistic about Reasons (2014) he defended the reality of reasons without the metaphysics that usually comes with such claims. Truths about what we have reason to do are objective, he argued, and cannot be reduced to facts about biology or desire. They form their own domain, as the truths of mathematics do, open to reasoning though not to the microscope.
In Why Does Inequality Matter? (2018) he argued that inequality is not simply a question of who has how much. Unequal wealth and power corrode the relations among citizens. They breed domination, humiliation, dependence, exclusion, and the capture of politics by the rich. Different inequalities carry different objections. The concept holds more than a single complaint.
His influence runs well past the seminar room. Legal scholars borrow contractualist reasoning for constitutional interpretation and the theory of rights. Bioethicists reach for it on questions of consent and the sharing of scarce care. And then, in a turn no philosopher plans for, his ideas reached millions through a network sitcom about the afterlife. Michael Schur (b. 1975) built the NBC comedy The Good Place around What We Owe to Each Other. He named an episode after it. The character Chidi, a professor of moral philosophy frozen by his own indecision, teaches the book to a dead woman named Eleanor as she tries to earn her way into a better place. Scanlon, told that a comedy had taken his treatise for a script, praised its fidelity to the philosophy. A moral theory written in careful analytic prose found a second life as a punchline and a plot.
His critics press from both sides. Consequentialists say contractualism weights the loudest individual complaint too heavily and the sum of small benefits too lightly. Kantians say it lacks the deep grounding that autonomy and the categorical imperative supply. Others doubt that reasonable rejection yields one answer in the hard cases, where reasonable people reject different things. Even the critics grant that his theory stands as a principal alternative to utilitarianism and Kantian ethics.
He works in the grain of analytic philosophy at its most patient. He builds no grand system. He takes one problem at a time, draws his distinctions, tests them against odd and telling cases, and answers the strongest form of the other side. His prose stays calm even where the conclusions run far. A reader can miss the size of a claim because he states it so evenly.
The honors came. He won a MacArthur Fellowship in 1993. He kept working into his eighties and published Morality and Responsibility in 2025, returning once more to blame, agency, and reasons. He is the father-in-law of the philosopher Tommie Shelby, who works on race and political philosophy at Harvard, so the discipline runs in the household. He retired from teaching in 2016 and holds the title of emeritus.
Change the question and you change the subject. For most of its history moral philosophy asked what brings about the most good, or what duty reason lays on us whatever our ties to other people. Scanlon asked something a person can act on across a table. What could I justify to you, and you to me, as equals who have to share a world? He put that mutual justification at the center of ethics and turned a neglected tradition into a main road. It is the question of the man on the stairs at Emerson Hall, the one who thought the students had it backward. Do not use your mind to win. Use it to find out whether you could look the other person in the eye and defend what you believe.
Notes
The opening scene is based on documented reporting rather than invention. The Sunday in February 2012, the debate tournament filling Emerson Hall, Scanlon’s irritation giving way to a loud laugh, his remark about would-be Sophists who score points instead of examining their own beliefs, the third-floor office, the long table, the fading light over Harvard Yard, and the Lorenzetti fresco of good government all come from Yascha Mounk’s interview with him. The same interview also provides the physical description of Scanlon as tall and lanky, with a long face and large hands, together with the observation that everyone calls him Tim: The Utopian.
The account of his childhood in Indianapolis comes from the biographical section of that same interview, republished with additional background by *Books & Ideas*. It includes his Irish immigrant father, who financed college with a paper route before becoming a litigator devoted to the American constitutional system, the constitutional discussions at the family dinner table, his college-educated mother, who had studied philosophy and remained at home, his parents’ encouragement to “go East,” the large public high school that he loved for its diversity, his original plan to major in mathematics, his senior thesis in the philosophy of mathematics, Paul Benacerraf’s encouragement, his initial intention to attend Harvard Law School, the last-minute decision to accept a Fulbright instead, his study with Michael Dummett at Oxford, his dissertation in logic under Burton Dreben, his later judgment that he lacked originality in logic, and his view that his work on freedom of expression continued the arguments that had begun around his family’s dinner table: Books & Ideas.
The account of Gregory Vlastos inviting John Rawls to present “Justice as Reciprocity,” Scanlon attending as an inexperienced undergraduate who could not yet distinguish good philosophy from great philosophy, his first meeting with Rawls after arriving at Harvard in the fall of 1963, and the 1984 conversation in which Rawls visited Princeton under the pretext of discussing philosophy before offering him the chair all come from the same Books & Ideas interview.
The famous discussion group, including the monthly routine of circulating papers in advance, spending an hour over lunch and conversation before debating from 1:30 until 5:30 in the afternoon, and the difficulty of getting recognized to speak, is described in the Books & Ideas interview. Scanlon’s statement that this group was the single most important influence on his philosophical development comes from a separate interview with the Brown Political Review: Brown Political Review.
The exchange with G. A. Cohen on a Princeton bus in the mid-1970s, when Cohen was more attracted to Robert Nozick than to Rawls and Scanlon teased him that a Marxist ought to care more about institutions than personal virtue, comes from Part V of the Yascha Mounk interview: The Utopian.
Rawls’s observation that Scanlon’s argument about rights seemed persuasive but did not appear genuinely consequentialist, together with Scanlon’s account of arriving at contractualism around 1979, comes from the Books & Ideas interview. I rendered these exchanges as paraphrase rather than direct quotation, because reconstructed dialogue reads more naturally than extended block quotations.
His MacArthur Fellowship in 1993 and his appointment as Alford Professor of Natural Religion, Moral Philosophy, and Civil Polity are documented by the MacArthur Foundation and the Harvard Department of Philosophy. The references in The Good Place, including Michael Schur’s admiration for Scanlon, the episode titled after *What We Owe to Each Other*, the characters Chidi and Eleanor, Tommie Shelby’s relationship as his son-in-law, and the publication of *Morality and Responsibility* in 2025 are documented at Wikipedia.
Self-evident extrapolations I made without a link: the gray weather (the interview calls it a dreary day), the students muttering arguments before a debate round, and the closing image of looking someone in the eye, which restates his own relationship-based account of blame.
If John J. Mearsheimer’s anthropology is right, the contractualist moral philosophy of T. M. Scanlon (b. 1940) stands as an elegant description of how humans justify their behavior within a secure subculture, mistaken for a universal description of moral motivation.
Scanlon, a leading American philosopher and author of What We Owe to Each Other, develops a distinctive form of moral contractualism. He argues that an act is wrong if its performance under the circumstances would be disallowed by a system of rules for the general regulation of behavior which no one could reasonably reject as a basis for informed, unforced, general agreement. For Scanlon, the core of morality is the desire to be able to justify one’s actions to others on grounds they cannot reasonably reject. This mutual recognition forms the basis of a non-utilitarian, reason-based account of our duties to other human beings.
Mearsheimer’s framework in The Great Delusion cuts through this contractualist ideal, showing that Scanlon’s philosophy reverses the true relationship between reason, group survival, and moral codes.
First, Scanlon treats the individual as a baseline rational actor whose primary moral drive is a desire for reasonable justification. Mearsheimer’s anthropology counters that reason is the least important way humans determine their preferences and foundational worldviews. The long human childhood ensures an intense value infusion from the primary group long before an individual can engage in the sophisticated testing of principles. This early socialization creates a localized, particularistic moral code rooted in group loyalty and collective survival. The deep-seated desire to justify oneself operates powerfully inside the tribe, where shared socialization establishes what constitutes a reasonable argument. It cannot scale seamlessly to a borderless community of abstract rational agents.Second, Scanlon’s formula relies on the premise of an unforced, general agreement. He describes a marketplace of reasons where individuals sit as equals, evaluating principles without coercion.
If Mearsheimer is right, this non-coercive environment is a structural illusion. Humans organize into distinct, cohesive groups primarily to secure survival in an anarchic world where there is no higher authority to protect them. The rules a society develops are engineered to maintain internal strength, coordinate defense, and navigate external competition. When resources tighten or an existential threat emerges, the luxury of seeking principles that a distant outsider cannot reasonably reject vanishes. The tribal state will enforce rules that ensure its own survival, regardless of whether those rules are reasonable to competitors or adversaries.
Finally, Scanlon’s model assumes that the boundaries of moral relevance are universal, encompassing any person capable of assessing reasons.
Under Mearsheimer’s lens, this universalist reach misreads the fundamental logic of group security. Moral communities are closed systems. Internal cooperation and mutual justification exist to keep the group cohesive against outside forces. A philosophy that treats the standard of reasonable rejection as a global, uniform baseline ignores that different societies, socialized into fundamentally incompatible worldviews, have completely different understandings of what is reasonable. What a Western contractualist views as a neutral, universal principle, a member of another culture might see as a tool of ideological encroachment.
If Mearsheimer is right, Scanlon’s philosophy describes the refined verbal behavior of individuals operating within a highly stable, affluent, and secured subculture. It captures the logic of internal group consensus but misses the external engine of human survival. Humans do not build societies by matching abstract reasons with strangers; they build them by binding themselves to a specific tribe to survive a dangerous world.
If David Pinsof is right, the contractualist moral philosophy of T. M. Scanlon (b. 1940) represents a beautifully constructed, high-status effort to transform raw coalitional warfare into a polite committee meeting about mutual justification.
In his foundational book What We Owe to Each Other, Scanlon argues that morality is built on a specific motive: the desire to be able to justify one’s actions to others on grounds they could not reasonably reject. In his view, wrong actions are not just social infractions; they are structural errors in reasoning, where an individual uses a principle that fails the test of universal, un-rejectable consensus. To his followers, Scanlon provided an objective, secular anchor for ethics, suggesting that human moral conflict can be resolved if we sit down and filter our principles through the lens of reasonable agreement.
A Pinsofian analysis strips away this high-status, contractualist narrative. Human beings do not seek to justify their actions because they possess an inherent, disinterested drive for logical consensus with all mankind. They deploy justifications as strategic, self-serving weapons. Natural selection designed the human brain to use moral language to recruit allies, police internal compliance within a faction, and demonize external rivals. When an individual argues that a principle is “unreasonable to reject,” he is not performing an objective logical calculation; he is signaling coalitional alignment and trying to impose his group’s preferred rules onto a competing faction to deprive them of resources or status.
By framing intense Darwinian struggles over power, reproduction, and property as a search for reasonable justification, Scanlon creates an ideal mission statement for the academic class. It positions the elite political philosopher as the ultimate referee who determines which reasons are valid and which are “unreasonable.” This framework provides university circles with a sophisticated platform to look down upon the instinctual, zero-sum behaviors of the masses, allowing adherents to signal immense moral and intellectual superiority by claiming their own political and social preferences are the only ones that pass the test of universal reason.
Scanlon did not discover a fundamental, non-deceptive engine for human cooperation. He executed a flawless academic strategy, converting dense ethical theory into high-status currency at the absolute peak of the university hierarchy. His work functions as an exceptionally effective apparatus to secure a dominant, high-prestige position—anchored by a long tenure as a Alford Professor at Harvard University—proving that defining the rules of mutual justification is the ultimate way to win the academic game.
