Hostility toward freedom of speech in American colleges and universities has been growing quietly for decades, but lately it has become impossible to ignore.
The toleration of unpopular opinion was once considered central to the purpose of a liberal education, which was not to indoctrinate students dogmatically but to teach them how to form beliefs.
But these classically liberal norms of toleration and open inquiry have given way to an activist conception of the mission of higher education. In practice, this amounts to the establishment of a specific ideology that its advocates refer to only in such generic terms as “social justice.”



Dissent from this new orthodoxy is increasingly treated as heresy: beyond the pale of argument. The irony of this retreat from the classically liberal mission of the university is that it vindicates the very arguments for freedom of speech and intellectual diversity that it rejects.
