Career
His date of birth is uncertain, but he was teaching before 1184, as he signed a document at the same time as Gerard de Pucelle, the Bishop of Coventry, who died that year. Simon taught philosophy for ten years, and was said to be brilliant. Then he moved on to teaching theology, with equal success.
He used the writings of Aristotle, whose works were becoming known, and other philosophical works.
This eventually brought suspicion upon him from the enemies of the new philosophy. This article incorporates text from a publication now in the public domain: Herbermann, Charles, educated
