"Still rarer is the man who thinks habitually, who applies reason, rather than habit pattern, to all his activity. Unless he masques himself, his is a dangerous life; he is regarded as queer, untrustworthy, subversive of public morals; he is a pink monkey among brown monkeys -- a fatal mistake. Unless the pink monkey can dye himself brown before he is caught.
The brown monkey's instinct to kill is correct; such men aredangerous to all monkey customs."
-Kettle Belly Baldwin in Gulf from Assignment in Eternity (Robert Heinlein)
