Anselm of Canterbury

1033-1109 · Italian (Aosta), monk of Bec, Archbishop of Canterbury · Philosophy of Religion, Metaphysics, Philosophical Theology, Christology

Hence, there is no doubt that there exists a being, than which nothing greater can be conceived, and it exists both in the understanding and in reality.

A boy from Aosta in the Burgundian Alps drifted north to the monastery of Bec in Normandy, fell under the spell of its great teacher Lanfranc, and ended his life — reluctantly, embroiled in bitter quarrels with English kings over the rights of the Church — as Archbishop of Canterbury. Anselm of Canterbury was the most important Western theologian between Augustine and Aquinas, and his motto names his whole method: credo ut intelligam, I believe in order that I may understand. Faith comes first, but reason does real work within it.
