 Another problem was that Tempier did not identify the targets of his condemnation, merely indicating that it was directed against unspecified members of the Arts Faculty in Paris. Siger of Brabant and Boethius of Dacia have been singled out as the most prominent targets of the 1277 censure, even though their names are not found in the document itself, appearing instead in the rubrics of only two of the many manuscripts that preserve the condemnation. These two scholars were important proponents of the Averroist movement. The ground-breaking study by the historian Roland Hissette has shown that many of the censured propositions appear to have come from Aristotle, from Arab philosophers, or from "the philosophers" (i.e. other Greek philosophers).
