“By the way the author is not an Objectivist and does not promote Objectivism”
For him to deny Hume’s positive impact on the evolution of “his” philosophy is ignorant. To deny Rand’s is just laughable. He can call himself what he wants, but he is Objectivist in ideas, tone, and even word choice.
I suppose his next article will be a similar hit piece on Rand. For completion’s sake, he can afterwards write a hit piece on himself.
