St Anselm, bishop, doctor of the Church

We learn about the Ontological Argument for the existence of God at Philosophy of Religion. I think it's one of my favourite topics. It really is a piece of genius. William Rowe (an atheist, and the author of our textbook) calls it "one of the high achievements of the human intellect."
While most philosophers no longer thing it's an adequate proof of God's existence, it still is an amazing word of philosophy.

Well, today's the feast day of the man who developed the onotological argument: St Anselm of Cantebury.

Anselm was born in northern Italy in 1033. From his home he could see the Alps mountains. When he was fifteen, Anselm tried to join a monastery in Italy. But his father was against it. Then Anselm became sick. Not long after he got better, his mother died. He was still young and rich and clever. Soon he forgot about wanting to serve God. He began to think only of having good times. After a while though, Anselm became bored with this way of life. He wanted something better, something more important. He went to France to visit the holy Abbot Lanfranc of the famous monastery of Bec. Anselm became Lanfranc's very close friend and the abbot brought him to God. He also helped Anselm decide to become a Benedictine monk. Anselm was then twenty-seven. Anselm was a warm-hearted man who loved his brother monks dearly. Even those who first resented him soon became his friends. He became the abbot in 1078. When he had to leave Bec to become archbishop of Canterbury in England, he told the monks that they would always live in his heart. The people of England loved and respected Anselm. However, King William II persecuted him. Anselm had to flee into exile in 1097 and in 1103. King William even forbade Anselm to go to Rome to ask the pope's advice. But Anselm went anyway. He stayed with the pope until the king died. Then he went back to his diocese in England. Even in the midst of his many duties, St. Anselm always found time to write important books of philosophy and theology. He also wrote down the many wonderful instructions he had given the monks about God. They were very happy about that. He used to say: "Would you like to know the secret of being happy in the monastery? Forget the world and be happy to forget it. The monastery is a real heaven on earth for those who live only for Jesus." St. Anselm died on April 21, 1109. He was declared a great teacher or Doctor of the Church by Pope Clement XI in 1720. "You were looking for God, and you have discovered that he is the Supreme Being, and that you could not possibly imagine anything more perfect. You have discovered that this Supreme Being is life itself, light, wisdom goodness, eternal blessedness, and blessed eternity."-St. Anselm

Faith seeking understanding

Anselm wrote this discourse, not from the perspective of an attempt to convince non-Christians of the truth of Christianity, but rather from the perspective of a Christian believer seeking a rationale for his/her faith. His original title for the discourse, in fact, was Faith Seeking Understanding. The Proslogium is the source for Anselm's famous and highly controversial ontological argument for the existence of God--that is, the argument in favor of God's existence by definition. While opinions concerning the ontological argument vary widely (and have from the moment the Proslogium was written), it is generally agreed that the argument is most convincing to Anselm's intended audience: that is, Christian believers seeking a rational basis for their belief in God.

The Argument (after Dr. Scott H. Moore's analysis)

1. One can imagine a being than which none greater can be conceived.
2. We know that existence in reality is greater than existence in the mind alone.
3. If the being we imagine exists only in our mind, then it is not a "being than which none greater can be conceived".
4. A being than which none greater can be conceived must also exist in reality.
5. Failure to exist in reality would be failure to be a being than which none greater can be conceived.
6. Thus a being than which none greater can be conceived must exist, and we call this being God.
