A list with a set of objective criteria wouldn't be OR. But I don't see how you would compile such a list without being subjective. Obviously you'd have to have RS saying the subject as influenced by A, but then you would have to decide which subjects were significant/important enough to be on the list. That's where the OR would come in. In answer to your question, if anywhere, she could be mentioned at Aristotelianism. What I don't know is how important Ayn Rand is as an Aristotelian philosopher.
