Italian-born English monk, abbot, theologian, Archbishop of Canterbury and Doctor of the Church. Helped inaugurate scholasticism in the medieval period, being credited as the "father of scholasticism", and became known for what became known as the "ontological argument" for the existence of God.
He entered the Benedictine order at the abbey of Bec at the age of 27 years in 1060 and served as abbot in 1079.
Anselm of Canterbury, also known as Anselm of Aosta or Anselm of Bec, was a monk and abbot at the Benedictine abbey of Bec. He served as Archbishop of Canterbury under William II from 1093 to his death on 1109.
As a result of the investiture controversy, the most significant conflict between Church and state in Medieval Europe, Henry I again from 1105 exiled him to 1107.
A bull of Clement XI, pope, proclaimed Anselm a doctor of the Church in 1720 . We celebrate his feast day annually on 21 April.
Proslogion: This short book is a defense of God based on the ontological argument. From what I understand, St. Anselm basically came up with this argument. The premise is that we can reason who God is and what He is by reasoning Him out - by sola ratione. It is interesting to think about, but has several glaring flaws, not the least of which is that it completely ignores the doctrine of total depravity - that man cannot understand, let alone choose, good without grace from above. Of course, since St. Anselm was a Catholic, he likely didn't believe in this doctrine anyway.
I thought this book was intriguing, and it offered some good discussion in our study group. I would not recommend it to a casual reader though; there are many better books to read theologically-speaking. But as an educational exercise, go for it.
