Ah, that explains it then: a Randian clinging to Rand’s crabbed version of rationalism. Wants to hide the fact that the EPR experiment has actually been carried out and local determinism overthrown, rather like Pythagoras wanting to hide the fact that the square root of two can’t be written as a fraction, so quantum mechanics is tossed into a list of disfavored things. (Odd, that, I personally suspect that quantum effects are the way free will actually gets implemented in the material world, but I guess Randians would rather live in Newton’s non-existent clockwork world than the real one we actually inhabit with all its weirdness.)
Well, I’ll confirm my judgment that Peikoff is an idiot, though I repent of my judgment that he is a post-modernist.
