Philip became chancellor of Notre Dame in 1217, a post largely concerned with the teaching work of the associated school. His philosophical significance is due to Summa de bono, a study of the goods of nature, creation, grace, virtue and gifts of God. One major impact was through the theory of those properties that transcend Aristotle’s categories—the transcendentals, other discussions to attract attention included psychology of action, freedom of the will, and time and eternity. Those influenced by his work included Albert the Great.
