Anselm of Canterbury

Anselm of Canterbury (1033–1109) was an Italian-born Benedictine monk, prior of Bec in Normandy, and archbishop of Canterbury from 1093. He is best known for the ontological argument in the Proslogion and for the theory of atonement in Cur Deus Homo. His Monologion and Proslogion set out his method of faith seeking understanding, and his letters and prayers reveal a devotional theologian. He was a central figure in the disputes between the English church and the Norman kings over investiture and papal authority, and he died in exile in 1109.
