Proslogian 2 supports the existence of God by arguing that if something could exist in the mind or in the mind and reality, then it would be greater in the mind (in intellectu) and in reality (in re). The Painter Analogy is used to demonstrate this since no matter how great a painting is in the Painter's mind, the painting on the canvas, in reality, will always be greater. This can be applied to God. If God is TTWNGCBC, then by definition God must exist in the mind and in reality, since that is the greatest option and God has the greatest "ontos" (being). Therefore, God exists.
