I can't now, since my statement would then be false. :)

Seriously though, I thought about it, but then I realized that I would probably have to replace the entire paragraph, since it seems to be a key step in the original author's explanation.

Maybe I will replace it anyway, since it can't be a very good explanation if it relies on faulty logic.

Update: Did it. Now I'm contradicting myself. Gotta' love these logic games.

If this sentence is true, then Santa Claus exists.

Basically assume A is true then the non existence of Santa Clause is a contradiction so A is false.

If (A then B) says nothing if A is false so your done.
