I recently listened to apologist Peter S. Williams (blog) deliver this talk at the 2010 European Leadership Forum on the topic: Arguments for Theism, and finally understood the Ontological Argument for God’s existence.
However, it brought up a question in my mind, which I submitted to William Lane Craig’s website. I’ll post the answer if I get one, but here’s the question:
If the Ontological Argument assumes that God is the maximum quality of attributes of goodness and greatness:
- Which category does ‘being’ or ‘existence’ fall into? Goodness or greatness?
- If that is an attribute of greatness, could we not then use this argument to argue for the existence of a maximally great and maximally evil (instead of good) being, then conclude that that being must also exist?
