“The intellect is prompted by nature to comprehend the whole breadth of being. … Under the concept of truth it knows all, and under the concept of the good it desires all.”

What Would You Substitute for the Bible as a Moral Guide? (1900)
Context: These religions teach the slave virtues. They make inanimate things holy, and falsehoods sacred. They create artificial crimes. To eat meat on Friday, to enjoy yourself on Sunday, to eat on fast-days, to be happy in Lent, to dispute a priest, to ask for evidence, to deny a creed, to express your sincere thought, all these acts are sins, crimes against some god, To give your honest opinion about Jehovah, Mohammed or Christ, is far worse than to maliciously slander your neighbor. To question or doubt miracles. is far worse than to deny known facts. Only the obedient, the credulous, the cringers, the kneelers, the meek, the unquestioning, the true believers, are regarded as moral, as virtuous. It is not enough to be honest, generous and useful; not enough to be governed by evidence, by facts. In addition to this, you must believe. These things are the foes of morality. They subvert all natural conceptions of virtue.
