A special New York Times Education supplement is out today, with notable contributions by John Palfrey on diversity and free expression, and Abby Ellin on the protection of free speech. There’s also a piece by Frank Bruni on how exorbitant tuition costs can create student entitlement.

Nicholas Christakis has a piece on inclusion as well. Christakis was personally affected by a political controversy at Yale, where he teaches in the sociology and medicine departments. Here is an excerpt from his piece:

Open, extended conversations among students themselves are essential not only to the pursuit of truth but also to deep moral learning and to righteous social progress. The faculty must step up and show students a way forward: to learn to be harder on the problems we face in our society, but easier on each other. We must demonstrate that we cannot be a community of searchers and learners if we do not share the same principles at the core of our universities.

And so the faculty must cut at the root of a set of ideas that are wholly illiberal. Disagreement is not oppression. Argument is not assault. Words — even provocative or repugnant ones — are not violence. The answer to speech we do not like is more speech.
