I have always liked one argument for the existence of God above all others: the Ontological Argument developed by St. Anselm, a great Christian thinker.
It is fun and interesting to consider because it is a priori, it requires no empirical evidence.
The proof goes something like this:
1. By definition, God is a being that than which no greater can be conceived.
2. God exists in the mind; He is conceivable.
3. A being that exists in the mind and in reality is greater than a being that exists only in the mind.
4. If God exists only as an idea, than we can conceive of a being greater than God—a being that exists as an idea and in reality.
5. As by definition God is a being that than which no greater can be conceived, God cannot exist only as an idea—thus he must exist in reality.
(Please don’t put too much reliance in the words I use to form the argument, it is their meaning that matters.)
Another way of looking at this is that there are four possibilities:
1. God exists in neither the imagination or in reality.
2. God exists in the imagination but not in reality.
3. God exists does not exist in the imagination but does exist in reality.
4. God exists in both the imagination and in reality.
Possibilities 1 and 3 are unacceptable as God exists in our imagination.
Possibility 2 is unacceptable because of the proof: if God is greater than anything else conceivable, and if we can conceive a greater God than one existing only in the imagination (a God that exists), than a God existing only in the imagination becomes a contradiction: we cannot imagine a being greater than the greatest possible being that can be imagined. We are left with only possibility 4: God exists in both the imagination and in reality.
