Well, you've never read Rand's "Introduction to Objectivist Epistemology" because -- in that work -- she improves substantially upon Aristotle's work, and what you seem to have learned from Aristotle can be found in Rand's epistemology.
LOL! So Ayn Rand one-ups the Tutor of Alexander, eh?
Thanks for the best laff of the evening! Somewhere, I think, Aristotle must be chuckling, too. "Improves upon Aristotle" indeed!
