"Classical morality in its decay became an instrument in the hands of commonplace energy to overthrow distinguished men. A true system of morals is from the first a weapon in the hands of the most distinguished. The Catholic Church created a system only possible for saints, hence its prolonged power. Its definition of good was narrow, but it did not set out to make shopkeepers. A lofty morality should be tolerant, for none declare its laws but those worn out with its warfare, and they must pity sinners. Besides, it must needs take a personal form in their minds and give to those minds the timidity of discoverers, not less than the courtesy of soldiers."
