If a definitive history of the controversy during the final decades of the thirteenth century regarding the real distinction between essence and existence still remains to be written, an exposition of the views expressed by Godfrey of Fontaines on this point may provide one more step in this direction. It seems probable that Godfrey had studied in Paris during Thomas' final years there (1269-1272) and that he may have studied under Henry of Ghent as well as under Siger of Brabant. He lectured as Master of theology at Paris for some thirteen years (1285-1297), and again around 1303-1304, when he composed his fifteenth Quodlibetal Question. Giles of Rome had also studied at Paris under Thomas (1269-1272) and served there as Bachelor in theology (1276-1277), and later as Master in theology (1285-1291). Henry of Ghent had taught at Paris around 1271 (apparently on the faculty of Arts) and later, beginning in 1276, on the faculty of Theology. Between 1276 and 1292 he delivered the courses which resulted in his Summa and in his Quaestiones Quodlibetales. Because Godfrey was familiar with the work of Thomas Aquinas (in Q[uodlibet] 2 q.3 one finds an almost verbatim reproduction of a section of Thomas' De aeternitate mundi), because he witnessed the famed debate on the real distinction between Henry of Ghent and Giles of Rome, and because his work was well known to Duns Scotus, clarification of his own position should be of historical interest. In addition, it is to be hoped that such a study will show that his views are distinctive enough to merit investigation for their own sake.
