The speculative part I was referring to in your account of abstraction was the claim about how we store relationships and properties:

All we're doing when we abstract is naming that set of properties and then storing that name and its relationships to other sets of properties as physical states of our brain.

Regardless of whether or not this is accurate, I'm just reminding you that the way we use our brains to store and retrieve such things is very much a black box. We simply have no idea how it works. We have nothing close to the neurological equivalent of a computer manual, so your claim is simply not valid. It's not unreasonable to suppose that there are seemingly crazy processes involved. If the history of science is a guide, it's probably the case.

We could discuss the history of science, but that's really outside of the OP and it's not clear to me why you keep pushing it in this thread. I brought up Aristotle because of his framing of the subject of souls in terms of the actualization of potentiality. We were also discussing the concept of relationship as abstraction. It's not clear to me how you see Newton tying into these discussions.

It's true that Aristotle was wrong about many things, though it's also true that the same can be said for most scientists throughout history, including Newton. As you correctly point out, one of the greatest errors on Aristotle's part was his acceptance of natural slavery. I think this is an excellent example as it illustrates the point of the difficulty of an abstraction like "relationship" when it comes to complex things. Natural slavery, like racism or sexism is basically a problem with, or a corruption of, the relationship between two or more groups of people. Aristotle mistakenly advanced the view that some groups of people are naturally lacking in intelligence and therefor unfit to rule themselves, and fit only to be ruled by more capable others. What Aristotle was missing, or perhaps failing to apply, was the idea of a natural soul consistently applied across all human beings. It would fall to other philosophical schools such as Stoicism to carry that flame.
