ABSTRACT
The Ontological Argument is very different. Its starting point is with the definition of God. It attempts to prove that God exists by examining the definition of what God is. The Ontological Argument is, therefore, an a priori argument. The Ontological Argument maintains that God exists is analytically true. People can find out whether God exists by coming to understand the word God. God cannot fail to exist. Saint Anselm, who was Archbishop of Canterbury from 1093 to 1109, thought that the Ontological Argument succeeded. He thought that God's existence could best be proved by analysing what it meant to talk about God. Rene Descartes put the Ontological Argument forward in a slightly different way. Descartes, like Anselm, maintained that existence cannot be separated from the idea of God. The same, in the anti-realist view, applies to the case of God, and this is what the second part of the Ontological Argument maintains.
