For some years outside my office door, I’ve had posted this excerpt from the American Association of University Professors Declaration of Principles on Academic Freedom and Academic Tenure (1915):
“The university teacher, in giving instruction upon controversial matters, while he is under no obligation to hide his own opinion under a mountain of equivocal verbiage, should, if he is fit for his position, be a person of a fair and judicial mind; he should, in dealing with such subjects, set forth justly, without suppression or innuendo, the divergent opinions of other investigators; he should cause his students to become familiar with the best published expressions of the great historic types of doctrine upon the questions at issue; and he should, above all, remember that his business is not to provide his students with ready-made conclusions, but to train them to think for themselves, and to provide them access to those materials which they need if they are to think intelligently.”
