 Brito goes on to claim that, more precisely, the subject matter of logic is concrete second intentions. The subsequent division of logic must then correspond to a division of concrete second intentions. Such a division is deduced from the three cognitive operations of the intellect: apprehension, composition/division, and deduction (Ebbesen and Pinborg 1981-1982: 309). A second intention qualifies the object of some of these intellectual operations. Correspondingly, the Categories deals with concrete second intentions understood through intellectual apprehension (e.g., man as substance, whiteness as quality, etc.). De interpretatione deals with concrete second intentions understood through composition and division (e.g., man as subject, white as predicate, a man being white as an assertion, etc.). Both Analytics, the Topics, and Sophistical Refutations deal with concrete second intentions understood through deduction. In other words, these treatises deal with things insofar as they are related to a syllogistic process, e.g., with the premise that every man is an animal (in the Prior Analytics), with the probability of a man being white (in the Topics), with the necessity of every man being an animal (in the Posterior Analytics), etc. (QsP; see Ebbesen &amp; Pinborg 1981–1982: 309 and 311).
