Ordinary morality is only for ordinary people.
Modern morality and manners suppress all natural instincts, keep people ignorant of the facts of nature and make them fighting drunk on bogey tales.
The conscience of the world is so guilty that it always assumes that people who investigate heresies must be heretics; just as if a doctor who studies leprosy must be a leper. Indeed, it is only recently that science has been allowed to study anything without reproach.

The supreme satisfaction is to be able to despise one's neighbor and this fact goes far to account for religious intolerance. It is evidently consoling to reflect that the people next door are headed for hell.
Adaptation to one's environment makes for a sort of survival; but after all, the supreme victory is only won by those who prove themselves of so much hardier stuff than the rest that no power on earth is able to destroy them. The people who have really made history are the martyrs.
