I consider the two venerated arguments about the existence of God: the Ontological Argument and the Argument from Evil. The Ontological Argument purports to show that God’s nature guarantees that God exists. The Argument from Evil purports to show that God’s nature, combined with some plausible facts about the way the world is, guarantees (or is very compelling grounds for thinking) that God does not exist. Both presume that it is coherent to predicate goodness (or greatness) of God. But if Peter Geach’s claim that goodness is logically attributive is cogent, then both arguments fall to the ground.
