I apprehend the Prior Analytics not as a treatise about a single “formal” theory but as a treatise on the deductive interplay between two such theories: (i) what Corcoran, Smiley and others have identified as the Syllogistic, and (ii) the fourteen syllogisms of the scholastics. The metatheory exploring their properties and deductive interaction is a contentual theory containing (primarily) the dicta, a pretheoretical reductio ad impossibile rule, and the square of opposition. The above interplay–I claim–culminates in the construction of the algorithmic apparatus in 1.28 aimed at availing both scientists and dialecticians. I take stock of some puzzling claims by Aristotle according to which whatever can be proved by reductio ad impossibile can also be proved ostensively. I argue that apprehending the content of the Prior Analytics that way vindicates these claims.
