From Russell Kirk’s Academic Freedom, 1955. (“Crawley” was a professor of medieval studies, and a good one, who’d had Communist ties. He disavowed them and swore he’d teach only the American Way of Life.)
…Professor Crawley never taught The American Way of Life in his classes. He did not know what The American Way of Life is, and neither do I. And even if he had believed in some dim ideology of Americanism, he would have been false to his trust as a servant of truth if as he had endeavored to indoctrinate students … in this dim ideology. He would have been as false to his trust as if he had taught The Marxist Way of Life. Professor Crawley, as a genuine scholar, always rose superior to indoctrination; in that he was worthy of academic freedom. But he ceased to be worthy of academic freedom, at least for the moment, when he agreed to pretend that he had been a propagandist for One Hundred Per Cent Americanism.
