By the time of Scotus, these 'commentaries' on the Sentences were no longer literal commentaries. Instead, Peter Lombard's original text was used as a starting point for highly original discussions on topics of theological or philosophical interest.See e.g. Wolter 1995, p. 76 and passim For example, Book II Distinction 2, about the location of angels, is a starting point for a complex discussion about continuous motion, and whether the same thing can be in two different places at the same time (bilocation). In the same book, Distinction 3, he uses the question of how angels can be different from one another, given that they have no material bodies, to investigate the difficult question of individuation in general.
