By taking ‘existence in reality’ to be a great-making property and ‘God’ to be the greatest possible being, Plantinga skillfully presents Anselm’s ontological argument. However, since he proves God’s existence by virtue of a premise, “God (a maximally great being) is a possible being”, that is true only if God actually exists; his argument begs the question of the existence of God.
