Do you think the Ontological argument proves the existence of god?

Before exploring the title of this essay we must understand the ontological argument. According to philosophers such as Anselm, it can be proven that God’s existence is necessary; it is, they argue, a tortology such as the statement ‘all bachelors are unmarried men’ an apriori analytic truth, falsifying such argument means self contradiction. The ontological argument reasons through 3 premises, and accepting that these to be true reach the conclusion that god must exist. The first premise states that: God is that which nothing greater can be conceived. The second premise states: that which nothing greater can be conceived possesses all perfections. The third premise states finally that: existence is perfection. Finally the conclusion reached is that if these premises correspond to reality is: God must exist.

The first premise in the ontological argument clearly states that god is that which no greater can be conceived. This means that he cannot exist only in our understanding as in order to be ‘that which no greater can be conceived’ god must fulfil existence in all forms of being. Because of the every nature of this God, he could not only exist in our understanding alone, as we could conceive something greater, such as a being that existed both in our understanding AND reality. And in that case, this being would be god, as by definition god is the greatest conceivable being. The ontological argument is an argument similar to that of a triangle. In order for a triangle to be a triangle, it must have 3 sides, it is in its nature, and a triangle needs 3 sides in order to exist as a triangle. It is necessarily true, it a contingent argument.

If we accept the three premises to be true then the conclusion is inevitable. However philosophers such as Kant, Aquinas and Guanilo found much criticism in this argument. This last philosopher, Guanilo, was contemporary to Anselm himself and criticised the argument in that it according to the grounds of the ontological argument, it was possible to prove the existence of any perfect being, and he took the example of a perfect island to demonstrate this. He constructed an ontological argument for the existence of a perfect island; by the same token, he argued that in order for the perfect ...
