"Remind students that one of the central missions of the university, which justifies its existence, is to get at the truth. That requires honest debate, patience, intellectual honesty, investigation, and a lot of hard work. But it also is not for the faint of heart. And that is a lesson that is almost never transmitted today. That offense, bruising thoughts, and unpleasant facts simply go with the territory. They are an intrinsic feature of an open society, and they never can be entirely avoided."
