" The capacity of a human mind to believe devoutly in what seems to me to be the highly improbable - from table tapping to the superiority of their own children - has never been plumbed. Faith strikes me as intellectual laziness, but I don't argue with it --- especially as I am rarely in a position to prove that it is mistaken. Negative proof is usually impossible. "

― Robert A. Heinlein , Stranger in a Strange Land
