 In addition to this fundamental inherence relation across categories, Aristotle also points out another fundamental relation that obtains between items within a single category. He describes this as the relation of “being said of a subject,” and his examples make clear that it is the relation of a more general to a less general thing within a single category. Thus, man is ‘said of’ a particular man, and animal is ‘said of’ man, and therefore, as Aristotle points out, animal is ‘said of’ the particular man also. The ‘said of’ relation, that is to say, is transitive (cf. 1b10). So the genus (e.g., animal) is ‘said of’ the species (e.g., man) and both genus and species are ‘said of’ the particular. The same holds in non-substance categories. In the category of quality, for example, the genus (color) is ‘said of’ the species (white) and both genus and species are ‘said of’ the particular white. There has been considerable scholarly dispute about these particulars in nonsubstance categories. For more detail, see the supplementary document:
