The true flaw in the ontological proof : Anselm, Kant, Husserl

God is a being than which nothing greater can be conceived. The Fool hath said in his heart that there is no God, and the Fool understands what he is saying. Thus, he thinks that God is only in the understanding but does not exist in reality. But since existing is greater than not existing, a God found in the understanding alone would not be a being than which nothing greater can be conceived, which contradicts the definition of what we are speaking about. Therefore, God is not only in the understanding, but exists.
