Categorical Notes I

-Aristotle beings his discussion of the Categories by noting how we speak. What we say of things is indicative of their categorical composition.

-To be said of something is different than to be in something. Ryan is a man = Ryan is an animal, Ryan is rational, etc. Ryan is white =/= Ryan is a color.

-Of all things said, substance is the most fundamental. Without it, nothing could be said of anything else. In a way, both species and genus are substances.

-Genus is said of the species, and these are both secondary substances. Primary substances are individual things (this horse, this man).
