 As should be clear from the above, Auriol’s extant works are predominantly theological in nature, having been composed in connection with his duties as a theological student and teacher. Nevertheless, especially his commentary on Peter Lombard’s Sentences is a treasure trove of philosophical thought spanning a vast range of issues in metaphysics, epistemology and philosophy of mind, natural philosophy, and ethics; it is in addition his most important and influential work. We possess several versions of Auriol’s Sentences commentary. Besides the Scriptum, which, as mentioned above, was mostly composed before Auriol arrived in Paris in the autumn of 1316, we have reportationes (student transcripts) of lectures that Auriol held on all four books of the Sentences, some of which have obviously been reworked to one degree or another by Auriol himself and some of which are still found only in medieval manuscripts. A version of his commentary on books II-IV was published in Rome in 1605 (along with Auriol’s single Quodlibet of sixteen questions). In part because the project to critically edit all of Auriol’s works has been initiated only recently, the complex relationship between these published texts and other versions, found only in manuscripts, as well as the relationship between the published Scriptum and the extant reportationes on book I of the Sentences, is not entirely clear. (See however, Nielsen 2002; Schabel 2000a, pp. 67–76; Schabel 2000b; Duba 2000; for more information on Auriol’s works, see the bibliography on the Peter Auriol Homepage (Other Internet Resources).)
