Étienne Tempier

Étienne Tempier (; also known as Stephanus of Orleans; died 3 September 1279) was a French bishop of Paris during the 13th century. He was Chancellor of the Sorbonne from 1263 to 1268, and bishop of Paris from 1268 until his death. He is best remembered for promulgating a Condemnation of 219 philosophical and theological propositions (or articles) that addressed concepts that were being disputed in the faculty of arts at the University of Paris. Life Born in Orléans, Tempier studied in Paris, where he became master of theology and canon of Notre Dame. During a period of about five years (1263–ca. 1268), Tempier was the Chancellor of the chapter of Notre Dame at Paris, succeeding Erich von Veire. At that time, the Chancellor of the Chapter was also the Chancellor of the University of Paris.

He served as bishop of Paris from 7 October 1268 until his death on 3 September 1279. Tempier had been a master in the faculty of theology.

Condemnations In 1270 Tempier, encouraged by Henry of Ghent (died 1293), had issued a formal condemnation of thirteen doctrines held by "radical Aristotelians". These included the unity of intellect, causal necessity, and the eternity of the world. Further investigation into perceived errors then prevalent at the university was prompted by the Portuguese cleric Juliani, who was elected Pope John XXI on 13 September 1276. A former professor of theology at the University of Paris, he wrote Tempier on 28 January 1277. The pope told Tempier that he had heard reports of heretical opinions in the Paris area, and requested to be informed of the situation. By this time Tempier was already investigating possible heretical opinions at the University of Paris.

On 7 March 1277, Tempier expanded the number of condemned doctrines to 219. He was assisted by a commission of theologians from the University. Henry of Ghent sat on Tempier's episcopal commission (assessores episcopi) of sixteen masters, which produced the syllabus of 219 propositions condemned by Tempier on 7 March 1277. The condemnations against Aristotelianism in Paris involved Giles of Rome, Siger of Brabant, the arts faculty, and certain doctrines of Thomas Aquinas. The forty-ninth item on the list was the assertion that God is incapable of moving the universe because it implies the existence of a void.

Opposition to and repeal Tempier's prohibitions did not curtail the free discussion of Thomist doctrines and did little to limit their influence at the University of Paris.
