“Each man's preference is the only standard for him, the only one which he can accept, the only one which can command him.”

“Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.”

“Man is the only animal that deals in that atrocity of atrocities War. He is the only one that gathers his brethren about him and goes forth in cold blood and calm pulse to exterminate his kind. He is the only animal that for sordid wages will march out... and help to slaughter strangers of his own species who have done him no harm and with whom he has no quarrel.... And in the intervals between campaigns he washes the blood off his hands and works for the universal brotherhood of man with his mouth.”

“Anyone who can only think of one way to spell a word obviously lacks imagination.”

“Satan must have been pretty simple, even according to the New Testament, or he wouldn't have led Christ up on a high mountain and offered him the world if he would fall down and worship him. That was a manifestly absurd proposition, because Christ, as the Son of God, already owned the world; and besides, what Satan showed him was only a few rocky acres of Palestine. It is just as if some one should try to buy Rockefeller, the owner of all the Standard Oil Company, with a gallon of kerosene.”

“We must have a religion — it goes without saying — but my idea is, to have it cut up into forty free sects, so that they will police each other, as had been the case in the United States in my time. Concentration of power in a political machine is bad; and and an Established Church is only a political machine; it was invented for that; it is nursed, cradled, preserved for that; it is an enemy to human liberty, and does no good which it could not better do in a split-up and scattered condition. That wasn’t law; it wasn’t gospel: it was only an opinion — my opinion, and I was only a man, one man: so it wasn’t worth any more than the pope’s — or any less, for that matter.”

“At certain periods it becomes the dearest ambition of a man to keep a faithful record of his performances in a book; and he dashes at this work with an enthusiasm that imposes on him the notion that keeping a journal is the veriest pastime in the world, and the pleasantest. But, if he only lives twenty-one days, he will find out that only those rare natures that are made up of pluck, endurance, devotion to duty for duty's sake, and invincible determination, may hope to venture upon so tremendous an enterprise as the keeping of a journal and not sustain a shameful defeat.”
