Encouraging religion to "beget" off!

You cannot prove a negative? Oh really?

I often read on atheist blogs and forums that “you cannot prove a negative”. This is untrue, and easily dis-proven because the statement is self-contradictory.

“You cannot prove a negative” is equivalent to “A proof of a negative statement does not exist”.

This is itself a negative statement (in the same sense as the statement “God does not exist”) which, by its own definition, cannot be proven! A contradiction. QED.

Hence, the statement “you cannot prove a negative” is no more than an unsupported assertion, or an example of “folk logic”. The next time someone blithely states “you cannot prove a negative”, please, put them right.

Or, better yet, ask them to prove it.
