Saint Anselm of Canterbury, a prominent medieval theologian and philosopher, is best known for his development of "ontological argument" for the existence of God and his contributions to scholastic theology. Anselm's theology is characterized by its intellectual rigor and its integration of faith and reason. In the Proslogion, he presents the ontological argument, which asserts that the very concept of a perfect God implies His existence. In Cur Deus Homo, Anselm addresses the question of why God became incarnate, arguing that the Incarnation and Atonement were necessary for the reconciliation of humanity with God. With his insistence on rational proofs of faith and his systematic approach to theological questions, Anselm's work had a profound impact on medieval and later Christian thought.
