History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help.

Robert A. HeinleinThe ethics of sex is a thorny problem. Each of us is forced to grope for a solution he can live with - in the face of preposterous, unworkable, and evil code of so-called 'Morals.'

Robert A. HeinleinOur behavior is different. How often have you seen a headline like this?--TWO DIE ATTEMPTING RESCUE OF DROWNING CHILD. If a man gets lost in the mountains, hundreds will search and often two or three searchers are killed. But the next time somebody gets lost just as many volunteers turn out.
