You Can Prove a NegativeIt is widely believed that you cant prove a negative. Some people even think that it is a law of logicyou cant prove that Santa Claus, unicorns, the Loch Ness Monster, God, pink elephants, WMD in Iraq and Bigfoot dont exist. This widespread belief is flatly, 100% wrong. In this little essay, I show precisely how one can prove a negative, to the same extent that one can prove anything at all.
