You pretty much hit one of the gaping holes from Aristotle, A fatal one if you ask me. However the commitment to Aristotle is a constant refrain of the hardest right, and its not accidental. In fact it's just rhetorically passable enough, to rationalize the egoism they require for whatever interests are at hand. It's because of this nature, a swiss cheese of philosophy, every piece of human excrement from Hitler, Ayn Rand, and Nietzsche starts with Aristotle for their claimed foundations. Simply stated, he was wrong then and he's still wrong now.
