James and Nell and Jonathan,
I have known a number of philosophers in academia, most of them not Objectivist. My impression is that among English-language philosophers today who have earned a PhD a significant number are realists concerning perception, science, and epistemology more generally. Overwhelmingly, at the same time, they reject foundationalism, especially of the axiomatic sort. The number of philosophers in agreement with Rand’s ethics, or with any egoistic ethics, is insignificant. (Eudaimonistic ethicists today also generally reject egoism.) Some philosophers defend the justice of laissez-faire capitalism, but not many in comparison to those opposing it.
There is overwhelming commitment to reason among those professional philosophers. Conceptions of reason will vary considerably, but they stand pat overwhelmingly against fideism, assertions without reasons, and logical fallacies (formal or informal). Overwhelmingly, they are atheists, outside of the religious schools. In sum there is significant concurrence with Rand on realism, reason, and atheism, but next to no concurrence with Rand on axiomatic foundationalism, egoism, or laissez-faire capitalism.
Those academic philosophers who have looked into Rand’s philosophy think they can refute it just fine. I imagine some of those philosophers who have not given a sustained look at Rand’s philosophy simply don’t have time for it, estimating it could not give them much help, given it is not academic philosophy. They have much other, definitely helpful work to study. They are pressed for time not only by shortness of life, but by competition from colleagues in their area.
Rand’s philosophy does give many other people much help, as you know. I expect it be will be around a while, and eventually someone might even bother to pull together a secularist and philosophically sophisticated book-length critique of the entire philosophy. At this point, however, it is unclear who would be the audience for such a work. Most people I’ve known with an interest in Rand’s philosophy either have an interest in it mainly for political organization or for the sake of themselves and their family. True, a few of us have studied philosophy widely beyond Rand, from all periods of philosophy, including our own, but few is few.
