  The inconclusiveness of Hissette’s study strongly suggests that research into the proximate background of the censured propositions has to be broadened. The directions that such research should take are indicated, either implicitly or explicitly, by Roland Hissette, and by other scholars such as John Wippel and Calvin Normore. Today it is generally agreed that a considerable number of the 219 censured propositions have a bearing on the reintroduction of pagan philosophy into the arts faculty, and on the ensuing crisis over the relation of faith and reason. Consequently, Greek or Arabic sources may prove to be at the origin of a number of censured propositions, as is also suggested in Tempier’s preface, in which he indicated that the scholars whose errors he condemned took their inspiration from pagan writings (cum errores praedictos gentilium scripturis muniant),  Other propositions may well have been derived from the teaching of theologians, such as Thomas Aquinas. In particular, John Wippel has argued (against Roland Hissette) that Aquinas’ teaching was also implied in Tempier’s condemnation and that some of the positions were taken from his writings. In this respect, the oft-quoted statement from Tempier’s introductory letter that members of the arts faculty were transgressing the limits of their own faculty (propriae facultatis limites excedentes) could acquire new meaning. Some members of the arts faculty were rebuked not only for teaching suspect philosophical views but also for teaching suspect theological views.
