Many people, like myself, think of Ayn Rand when we think of philosophy, having read her books when young, etc. Coming from this sort of background, it was surprising to me, recently, to be told that the majority of professional philosophers don't regard her as a philosopher at all, or, if they do, take little notice of her. Is that truly the attitude amongst philosophers? If so, is there any particular reason for it? For instance, is it to do with resistance to ideas that come from outside the university?
