None of us ever fully eludes true belief, or dogmatism. Bits of it cling to us in one way or another, like thistles in wool socks. Some make their dogmas obvious in the grand scale with which they dissent from ideas to which most of us nod. It is easy to see the dogmatism in the Maoist or the mystic, the positivist or the Platonist. What's harder to catch is the dogma in skepticism, the rhetoric in doubt.

There is, but it is not the morality that critics of colleges and universities sometimes call for, the unambiguous morality of do this and don't do that. We have an absolute prohibition on plagiarism, on submitting another's work as one's own. But the morality we teach is the morality of freedom, of free inquiry and free conviction. Whatever else they believed in, they believed in their students' ability to respond to serious challenge. They had no sense that we could not take it, that we would need coddling or soft-pedaling.
