Should a student saying “I am offended” be sufficient reason to cancel a lecture? What if it’s many students? What if members of the faculty are offended, too? It depends on what you think is the purpose of education. Hanna Holborn Gray, the president of the University of Chicago from 1978 to 1993, once offered this principle: “Education should not be intended to make people comfortable; it is meant to make them think.”
