Academic freedom has found its sanest and most far-seeing exponent in the President of Harvard University. The professor ought to be absolutely free in classroom teaching on subjects within the scope of his chair. He ought to be free to publish his lectures or the results of his investigations, subject only to the qualification that what he writes should be uttered in a scholarly tone and form. He ought not to foist upon a class that is compelled to listen to him opinions on subjects outside of the field of his special competence, but this is a minor point, not actually calling for discipline. As a man, he is bound to have opinions on other subjects than his own, and even though these opinions may in the judgment of most of his colleagues be injudicious and injurious to the institution of learning of which he is a member, it is still dangerous to place restrictions upon his uttering them outside of the class room. Men of ability will not enter the profession of university teaching if they are to be deprived of the rights of expression enjoyed by all other men. As to the theory that in time of war professors should be subject to special restrictions not applicable in time of peace, President Lowell rejects it unconditionally. On the assumption that the opinions that he utters are sincere, not couched in a form that gives evidence of moral obliquity, the professor ought to be free, and the Harvard professor, at any rate, is in fact free. --New Republic.
