Harvey Mansfield’s recent New York Post column about Harvard reads like a closing argument. After 61 years at Harvard, the university’s most famous conservative dissenter has finally written down the case he has been making to deaf ears since the 1970s. His title is blunt: “I was one of a few conservative professors at Harvard — here’s where the school went wrong.” The piece deserves a close reading, both because he is largely right and because his insights point to a deeper problem than the one he names.

Mansfield’s argument turns on the Ivory Tower—not the caricature, but the actual idea. A university, he writes, depends on America for its survival but tries to rise above its politics. Politics asks, “What should our welfare policy be?” The Ivory Tower asks the prior question, “What is welfare?” Harvard abandoned that distinction, and the evidence is everywhere: a vocabulary that turned woke, a legacy reframed in colonialism and slavery, affirmative action entrenched in admissions and hiring, and one political party permitted to dominate every part of the institution, including science. In 2023, Claudine Gay said the quiet part out loud: the Ivory Tower was obsolete, and Harvard would now act as “part of society.” Mansfield’s reply is two words: “What is the difference?”

He is right about the vulnerability. Once an institution is perceived as aligned with one side, it invites retaliation from the other. This is Tocquevillian common sense, and it is the story of the last two years in higher education: the congressional hearings, the donor revolts, the funding freezes, the Title VI investigations. Mansfield calls the current moment a siege, and he is correct that Harvard invited it by forfeiting its independence. He is right, too, about the mechanism. Universities did not become politically captured by accident. They did it deliberately, through decades of hiring patterns, curricular choices, and administrative growth that all tilted in one direction. Mansfield opposed this, in his words, “with sweet reason, the only weapon I had.” He was heard, he says, but not listened to.

That last line is where his argument runs into itself. If sweet reason was insufficient against a trend, Mansfield was right all along; the problem is not simply that Harvard lost its independence. The problem is that the people inside the institution stopped recognizing a good argument when they heard one. Sweet reason assumes an audience trained to weigh it. That audience has gone missing.

This sort of institutional damage runs deep. The Ivory Tower is not only a structure that protects inquiry from political pressure. It is a culture that trains people to think: to reconstruct arguments in their strongest form, to sit with frameworks they dislike, to distinguish evidence from assertion and moral intuition from policy consequence. When that culture is intact, sweet reason works because it meets minds prepared to hear it. When it is not, even a 61-year record of being proven right is insufficient, because nobody in the room has been taught how to be wrong. I watched it disappear. As an undergraduate and later a graduate student, I sat in classrooms with intellectual giants from across the political spectrum—Seymour Martin Lipset, William Julius Wilson, Samuel Huntington, James Q. Wilson, Jane Mansbridge, Susan Moller Okin, and my own advisor, Theda Skocpol. They disagreed with one another, with us, and often with themselves. They listened to everything. They made everyone think. You could not predict where a seminar would land, because the argument mattered more than the conclusion. The goal was not advocacy. It was clarity. That some of those same scholars later helped build the architecture Mansfield describes is part of the story, not a contradiction of it. Institutions capture even the people who once stood outside them.

That classroom model is largely gone, and with it the cultivation of deep knowledge. What replaced it is pedantic; it is a specific intellectual formation in which standpoint epistemology treats identity as a credential for knowing, reframes disagreement as harm, and “diversity, equity, and inclusion” sorts arguments by the social location of the person making them rather than by their evidentiary weight. In too many classrooms, students are no longer trained to interrogate ideas. They are trained to affirm them. They arrive with strong moral convictions and leave with those convictions reinforced, not examined. Ask the basic analytical questions—How does this policy work? What are the tradeoffs? Who bears the cost? — and the conversation stalls. Not because students lack intelligence, but because they have not been asked to move past the first-order claim. They have learned what to think. They have not been taught how.

I see this practically every semester at Sarah Lawrence, where I have taught for almost two decades. In a recent discussion of housing policy, students confidently asserted that rent control was necessary and that housing is a human right. These are not unreasonable starting points. But when I asked what happens to supply when returns are capped, or how zoning shapes construction, or what the distributional consequences of price controls become, the conversation stopped. It was not that the students resisted the questions. They had never encountered them. The same pattern holds for wages, trade, taxation, and healthcare. This is not a failure of values. It is a failure of education. In the spirit of Livy, deep knowledge requires friction—encountering arguments that do not fit one’s moral framework, sitting with them long enough to be changed by them. Those conditions are increasingly absent.

The classroom has become a site for signaling. The line between analysis and advocacy blurs, then disappears. Faculty who might otherwise push back have strong reasons not to: social pressure, reputational risk, peer sanction, hostile student evaluations, and the long shadow these cast on tenure and promotion. The problem reproduces itself: the graduate students now being trained to become the Lipsets and Mansbridges of 2045 are being trained inside the same captured institutions, by faculty who have already made their peace with the current culture. The surrender is quiet because the costs of resistance are not.

Mansfield closes by suggesting that Republicans, now awake to the woke universities, will not fall silent for the next administration or the one after. He may be right. Federal pressure, donor scrutiny, and declining public trust have all arrived at once. But political pressure alone cannot restore what has been lost. You cannot legislate back into existence the classroom culture that teaches students to think against themselves. That must be rebuilt from the inside and slowly, by faculty willing to reclaim a role most have quietly surrendered.

There are signs that the work is beginning. Chicago remains the philosophical standard, as reflected in the Kalven Report; MIT and Vanderbilt have taken meaningful steps toward institutional restraint; and Harvard itself adopted a narrower statement-neutrality policy in May 2024 following its Institutional Voice Working Group report. That adoption is real, and it matters. But it came only after congressional hearings, donor revolts, and a presidential resignation forced the question, and it is bound to what the institution says rather than how it teaches. A policy statement cannot by itself restore the classroom culture whose loss Mansfield’s piece implicitly mourns. Dartmouth under Sian Beilock has gone the furthest in translating neutrality into practice—reinstating standardized testing, enforcing grade medians, publishing outcomes data, and protecting individual faculty and student speech while restraining the institution’s political voice. These are exceptions, not yet a trend. But they are evidence that the culture can be rebuilt when faculty and administrators decide to do so.

Lipset, Wilson, Huntington, Mansbridge, Okin, Skocpol—they did not agree on much. But they agreed that the classroom was a place to argue hard and listen harder, and that the student’s job was to come out of it able to think, not merely to assert. That is the inheritance we have lost, and the inheritance Mansfield’s sweet reason presupposed. When universities stop teaching students how to think, they do not merely drift into politics. They abandon their purpose. The loss is not ideological. It is intellectual, and it is far harder to rebuild than to lose.
