"It must be that the increase comes of the inborn human instinct to imitate--that and man's commonest weakness, his aversion to being unpleasantly conspicuous, pointed at, shunned, as being on the unpopular side. Its other name is Moral Cowardice, and is the commanding feature of the make-up of 9,999 men in the 10,000. I am not offering this as a discovery; privately the dullest of us knows it to be true". Mark Twain
