Academic freedom gives professors broad discretion over expressions and interactions in the classroom. Free speech guidelines and First Amendment protections permit students to speak their minds too, but they offer very limited guidance as to how classrooms should operate. While professors should obviously work within free speech parameters in the classroom, there are two additional principles that should guide their work: the first intellectual and the second civic. First, as part of their commitment to teaching--developing and disseminating knowledge--instructors are bound by intellectual honesty in ways that can in fact limit their expression. Second, college teaching should contribute to the development of civic skills and values. A good college education would include at least some--and ideally many--instructors who see themselves not only as teaching in their field but also as educators who prepare their students for their broader roles in society. In this regard, instructors should devote some thought to the ways in which dissent, harm, and other forms of expression can present themselves in the classroom and how they might productively respond to free speech challenges.
