The university’s chief mission is the pursuit, refinement, and dissemination of knowledge and understanding about the world and humanity’s place in it. To best accomplish this mission, the university must nourish a culture of free inquiry—a culture where ideas are freely and vigorously exchanged, where thinkers from all walks of life can subject their perspectives to searching discussion, and where disagreement is a key means to test and advance the frontiers of knowledge. 

There is, however, an inescapable tension at the heart of free inquiry. One way to see the tension is simply by reflecting on the phrase “free inquiry” itself. The two words in the term pull against one another.

On one side is “free.” When something is free, it is unconstrained—wild even. Staunch defense of free speech on campus, from the McCarthy era in the 1950s to the free speech movement at Berkeley in the 1960s, through to our present time and the efforts of organizations like Heterodox Academy, is all a manifestation of the desire to lean into the “free” side of free inquiry. To lean this way is to place great importance on the open exchange of ideas, even by thinkers we find distasteful or immoral, as essential to the pursuit of knowledge and understanding. As John Stuart Mill put it in On Liberty, “There ought to exist the fullest liberty of professing and discussing, as a matter of ethical conviction, any doctrine, however immoral it may be considered.”

Mill’s picture is one where the forwarding of every opinion, even those that we take to be wrong, offensive, irrational, or immoral, is of great value to our growth in knowledge and understanding. Consider the history of anatomy, which relies on systematic dissection of human corpses. Progress in anatomy was severely impeded by authorities who viewed dissection itself as sacrilegious. It wasn’t until such views faded that we learned more about the marvels of the human body. The moral here: Let a great tide of opinion flow—even with all its mud and detritus—so that the tree of knowledge might be nourished.

But on the other side of “free” is “inquiry.” Far from the turbulence of converging currents of opinion, inquiry requires discipline. The very term “inquiry” conjures images of scholars hunched over stacks of books in hushed libraries, or scientists meticulously calibrating instruments to eliminate the slightest error. Inquirers follow well-worn methodological paths, subjecting themselves to rigorous standards of evidence, logic, and argument. They laboriously sift through mountains of information, weighing each piece, discarding much. 

They humble themselves before the collective wisdom of their disciplines, accepting criticism that may feel like personal rebuke—or even personal attack. And perhaps most difficult, they hold out their most treasured findings with open hands, knowing that what seems to be the most solid of truths may sublimate into vaporous ignorance in the face of new evidence.

In sum, inquiry demands constraint—the antithesis of unbounded freedom. The unfettered expression of opinion, so central to the “free” side of free inquiry, is just one actor of many on the stage of inquiry. The rushing river of free expression must be channeled through stone aqueducts and cast iron piping of disciplined investigation.

The temptation to minimize controversy often means dampening precisely that friction that generates sparks of insight.

Thus, the tension at the heart of free inquiry: Freedom demands openness to all opinions, while effective inquiry demands constraints and discipline. And because our universities must be homes to free inquiry, this tension is inescapable. More importantly, it’s a good thing. Consider a guitar’s strings: They can make their dulcet tones only if they are tuned to a certain tension. Remove it and the string buzzes discordantly or flops about lifelessly.

Those who lead and inhabit our institutions of higher education must manage this tension daily. Freedom without constraint leads to a buzzing cacophony, where ignorance can blot out knowledge, where understanding is confounded by confusion. But too much constraint dams the wellsprings of discovery, choking off the streams through which new ideas might surge. 

The challenge for those who wish to foster a culture of free inquiry is to strike the right balance—cultivating gardens where wild ideas may bloom, yet tilled and pruned enough to bear the good fruits of disciplined, rigorous inquiry. This tension cannot be resolved once and for all, but must be constantly negotiated through institutional practices and cultural norms.

Yet maintaining productive tension requires deliberate effort, particularly in communities where ideological homogeneity threatens to slacken the strings. When too many share the same assumptions, the instrument of inquiry produces only monotone droning rather than beautiful music. Universities must therefore cultivate what we might call “intellectual cross-training.” The progressive scholar learns to articulate conservative arguments in their strongest form; the methodologist practices wild speculation; the theorist submits to rigorous empirical discipline. These are not exercises in bad faith or false balance, but essential practices for maintaining the tension that makes real inquiry possible.

For our institutions’ leaders, the temptation to minimize controversy often means dampening precisely that friction that generates sparks of insight. But a university that celebrates only comfortable discoveries is like a bridge with all its cables pulling in the same direction—structurally unsound and awaiting collapse. Better to understand that productive disagreement is not a failure of a community but evidence of its health. 

This means seeking out people to join that community that unsettle departmental orthodoxies, funding research that tests rather than assumes foundational premises, creating structured encounters with those whose intellectual commitments pull in different directions. The goal is not chaos but a carefully maintained tension—taut enough to do real work and flexible enough to absorb the shocks of genuine discovery.
