Yes she does. Here she is saying so: "All the countless forms, motions, combinations and dissolutions of elements within the universe, from a floating speck of dust to the formation of a galaxy to the emergence of life, are caused and determined [ emph. added ] by the identities of the elements involved". "It's negation is a self contradiction" is a classical way of defining an apriori statement, found in much philosophical literature. So your objection is like saying "it's an equine quadruped, not a horse". Wrong. If your statement means anything, you conflate epistemology and metaphysics. A concept is not a physical box. "If the shoe fits" is not a literal call to find Cinderalla. I am referring to this claim by Peikoff: "Metaphysically, an entity is what it is, (it has all of the characteristics that it has) therefore there is no basis for saying that some characteristics are contained within the meaning of a concept and some are not, therefore there is no basis for the analytic/synthetic dichotomy'. " I agree that his idea of "containment within a concept" is both unclear and unlikely. If you want to say he is just plumb wrong. go ahead....although you will then need a substitute argument against the A/S dichotomy. Wrong. These are not Rand's words and she obviously recognized the need for a cassus belli. Well, Peikoff doesn't.
