  On March 7, 1277, the Bishop of Paris, Stephen Tempier, prohibited the teaching of 219 philosophical and theological theses that were being discussed and disputed in the faculty of arts under his jurisdiction. Tempier’s condemnation has gained great symbolic meaning in the minds of modern intellectual historians, and possibly for this reason, there is still considerable disagreement about what motivated Tempier to promulgate his prohibition, what exactly was condemned, and who the targets were. In addition, the effects of Tempier’s action on the course of medieval thought in the thirteenth and fourteenth centuries, and even beyond, has been the subject of much debate. The lack of a commonly accepted standard account of Tempier’s actions plus the enormous amount of literature and of textual evidence that either directly or indirectly bears on the events of 1277, puts specific limitations to the present entry. It will be confined to presenting those historical facts that are uncontroversial and to indicating the main issues of current debate with respect to Tempier’s condemnation.
