I have engaged in a little private back and forth discussion with the author of the article, and have forwarded him a couple of clips in support of my view of this. I will try to circle back and add some commentary but for future reference here are the clips.
Aaron it is my understanding from what Francis Wright wrote in "A Few Days In Athens" that Aristotle held "color" to be something that exists apart from the entity which we perceive to have color. Do you believe that to be incorrect?
Also, in part of my analysis I am relying on this commentary from commentator Philip DeLacy as to the Epicurean Philodemus' "On Methods of Inference" -->
The last reference I would throw into this pot is a comment by Richard Dawkins in which he seems to also place Aristotle in Plato's camp, as per DeLacy:
So to bring that back home to the discussion, my tentative diagnosis has been that by appearing to include "concepts" in her discussion of the law of identity (at least as many of her casual follows seem to do, and I can understand why) the implication of Rand is that concepts such as capitalism are also subject to categorization by "essentials" which leads to the Platonic idealism which at least on the surface Rand always campaigned against.
