French Guillaume d'Auxerre
born 0441; 1150, Auxerre, bishopric of Auxerre
died Nov. 3, 1231, Rome
French philosopher and theologian.
After a long career at the University of Paris, he was appointed in 1231 by Pope Gregory IX to a council to censor the works of Aristotle (which in 1210 had been deemed corruptive of Christianity) included in the university's curriculum. Seeing no reason to avoid the rational analysis of Christian revelation, he was on the verge of reorganizing the curriculum when he died. In his principal work, usually called the Summa aurea (written 121520), he treated such matters as God's triune nature, the problem of human choice, and the nature of virtue.
