It is possible to conceive…of a being than which nothing greater can be conceived. Even an atheist can conceive of such a superlative being, though he would deny its existence. But, goes the argument, a being that does not exist in the real world is, by the very fact, less than perfect. Therefor, we have a contradiction and, hey presto, God exists!

Let me translate this infantile argument into the appropriate language, which is the language of the playground:

- Bet you I can prove God exists.
- Bet you can’t.
- Right then, imagine the most perfect perfect perfect thing possible.
- Okay, now what ?
- Now, is that perfect perfect perfect thing real ? Does it exist ?
- No, it’s only in my mind.
- But if it was real it would be even more perfect, because a really really perfect thing would have to be better than a silly old imaginary thing. So I’ve proved that God exists. Nur Nurny Nur Nur. All atheists are fools.
