He does not introduce non-Aristotelian material to explain Aristotle; he does not even, for example, make reference to Porphyry's introduction to the Categories, the Isagoge, to help make sense of the Categories.
Boethius's Porphyrian approach is evident even in the two commentaries on Porphyry's own Isagoge (an introduction to the Categories which had become accepted as a standard part of the logical curriculum)—one text on which, obviously, Porphyry himself had never commented.
Before rating the radiographs, the observers were given schematics of the different fracture types and a written introduction to the difference between the categories.

The third (main) part of the course will focus on more recent developments: we will try to give a gentle introduction to simplicial categories and DG categories which are the main technical tools in several areas of modern mathematics (derived algebraic geometry, modern representation theory and noncommutaive geometry).
In the sequence of courses, the 'Prolegomena' were followed by lectures on Porphyry's seminal 'Introduction to Aristotle's Categories'.
In the third section, I will briefly discuss how the specific medieval questions concerning universals emerged, especially in the context of answering Porphyry's famous questions in his introduction to Aristotle's Categories, which will naturally lead us to a discussion of Boethius' Aristotelian answers to these questions in his second commentary on Porphyry in the fourth section.
