The University of Southern California is committed to fostering a learning environment where free inquiry and expression are encouraged and celebrated and for which all its members share responsibility. Dissent (defined as disagreement, a difference of opinion, or thinking differently from others) is an integral aspect of expression in higher education, whether it manifests itself in a new and differing theory in quantum mechanics, a personal disagreement with a current foreign policy, opposition to a position taken by the university itself, or by some other means.
