I stumbled across a paper written by James S. Cutsinger,actually a lecture given at Thomas Aquina College on 20 April 2001, which advances a stout defense of the ontological argument from Proslogion II. This form of the argument is largely regarded as having been defeated by such luminaries as Aquinas and Kant. So Cutsinger’s take on the OA was of great interest to me, a long-time fan of the argument in its modal form found in Proslogion III.
It goes like this:

It goes like this:
- God is that than which nothing greater can be thought (TTWNGCBT).
- TTWNGCBT can be thought.
- Whatever can be thought exists in the mind.
- Whatever exists in the mind either exists in the mind alone or exists also in reality.
- To exist in reality is greater that to exist in the mind alone. [Take this to mean: existing things as a class, are greater than any purely mental being. So, for example, a speck of dust is greater than an imagined mansion.]
- Suppose TTWNGCBT exists in the mind alone. But then this leads to a contradiction because if that were so, I could conceive of something greater, namely any particulare thing which exists in reality. Therefore, TTWNGCBT cannot exist in the mind alone.
- TTWNGCBT must exist in reality.
- Therefore God must exist.
