The ways in which we describe the world determine how we interact with it, perceive it, and understand it. In the Categories, Aristotle develops a logical system of classification for relating properties and substance to one another in a hierarchical manner. In order to do so, he develops a system of ontology that offers a quite different explanation from that presented by early philosophers, such as Plato in his Realm of Forms theory. Through his Physics, he further explains, drawing heavily on the Categories, how it is that the fundamental units of existence and properties undergo changes.
In the Categories, Aristotle proposes a set of ten fundamental things that exist (the categories) (RAGP, 696). Aristotle assumes that all aspects and manners of existence can be classified within these categories. He then seeks to demonstrate how they relate to each other by dividing existence into four parts, presented on 695. His first central claim is the organizing principle of the Categories, that there are essentially two fundamental relation or divisions on which the correct ontology is based; (not) being in or present a subject and (not) being said of subject and all things are subject to this division. According to this division, all subjects and attributes thus either are or are not said of a subject/present in a subject (RAGP, 694-695). Correspondingly, all objects can be said to be in or not in a subject as well. Thus a) Some things are said to be of a subject but not in the…
