 Let us take up the first four postulates. The first postulate concerns our supposed natural disposition to think; the denial of this is what necessitates our being forced to think. The second and third postulates concern subjective and objective unity. Subjective unity is captured by the notion of “common sense” such that our faculties of sensation, memory, imagination, and thought work in harmony, while objective unity is captured by the notion of “recognition” such that it is the same object that is sensed, remembered, imagined, and thought. The fourth postulate concerns “representation”, a key target of Deleuze’s critique. Here difference is submitted to a fourfold structure that renders difference subordinate to identity: 1) identity in the concept; 2) opposition of predicates; 3) analogy in judgment; and 4) resemblance in perception. A good way to approach Deleuze’s notion of representation is via Aristotle and Porphyry. Specific differences are the opposed predicates that function on a horizon of identity in the concept under division; thus animal is the genus that is divided into rational and irrational as specific differences that enable the isolation of the species “human.” Then, we find that the difference between individuals of the same species is infra-conceptual and can only be made via the perception of resemblances; Theaetetus looks like Socrates but not so much that they cannot be distinguished. Finally, the relation of substance to the other categories is analogical, such that being is said in many ways, but with substance as the primary way in which it is said.
