A Reaction

The idea seems to be that Aristotle is seeking tools for getting at the primary being of a thing, and the notion of 'form' strikes him as a better account, because it explains the genera and species, rather than just naming them.

The 23 ideas with the same theme [its class, and then its distinguishing feature]:

12355 'Plane' is the genus of plane figures, and 'solid' of solids, with differentiae picking out types of corner [Aristotle]
12352 Whiteness can only belong to man because an individual like Callias happens to be white [Aristotle]
11383 A definition is of the universal and of the kind [Aristotle]
10961 Definition by division is into genus and differentiae [Aristotle]
12356 If the genus is just its constitutive forms (or matter), then the definition is the account of the differentiae [Aristotle]
17040 If I define you, I have to use terms which are all true of other things too [Aristotle]
12081 Aristotle's definitions are not unique, but apply to a range of individuals [Aristotle, by Witt]
12353 Species and genera are largely irrelevant in 'Metaphysics' [Aristotle, by Wedin]
12261 Differentia are generic, and belong with genus [Aristotle]
12263 'Genus' is part of the essence shared among several things [Aristotle]
12272 We describe the essence of a particular thing by means of its differentiae [Aristotle]
12279 The differentia indicate the qualities, but not the essence [Aristotle]
12283 In definitions the first term to be assigned ought to be the genus [Aristotle]
12289 The genera and the differentiae are part of the essence [Aristotle]
4385 Aristotelian definition involves first stating the genus, then the differentia of the thing [Aristotle, by Urmson]
13070 If definitions must be general, and general terms can't individuate, then Socrates can't be defined [Aquinas, by Cover/O'Leary-Hawthorne]
11197 The definitions expressing identity are used to sort things [Aquinas]
17239 Definition is resolution of names into successive genera, and finally the difference [Hobbes]
12538 Genus is a partial conception of species, and species a partial idea of individuals [Locke]
12980 Genus and differentia might be swapped, and 'rational animal' become 'animable rational' [Leibniz]
14266 Aristotle sees hierarchies in definitions using genus and differentia (as we see them in sets) [Fine,K]
12242 Definition distinguishes one kind from another, and individuation picks out members of the kind [Oderberg]
12249 'Animal' is a genus and 'rational' is a specific difference [Oderberg]
