 The three theses mentioned above suggest a kind of identification of logic and metaphysics, especially since Burley wanted logic to be the theory of discourse on Being. Logic must be metaphysically grounded in the correspondence between the structural features of discourse (both between the subject and predicate of a proposition, as well as between the premises and conclusion of a syllogism) and the structure of reality. Burley maintains that logic is nothing but an analysis of the general structures of reality. In discussing the nature, status, and subject of logic in the introduction to his final commentary on the Ars Vetus (fol. 2rb–va), he claims that logic is about things of second intention as such, second intentions being those concepts of things (conceptus rei) that arise when we see the common nature in relation to the things that instantiate it. Logic is accordingly about structural forms, which are, as forms, independent of the mental acts through which they are acquired. Through these structural forms, the connections between the basic constituents of reality (individual and universals, substances and accidents) are disclosed.
