“MAN, n. An animal so lost in rapturous contemplation of what he thinks he is as to overlook what he indubitably ought to be. His chief occupation is extermination of other animals and his own species, which, however, multiplies with such insistent rapidity as to infest the whole habitable earth and Canada.”

“At the beginning of human history, man lost some of the basic animal instincts in which an animal's behavior is embedded and by which it is secured. Such security, like paradise, is closed to man forever; man has to make choices. In addition to this, however, man has suffered another loss in his more recent development inasmuch as the traditions which buttressed his behavior are now rapidly diminishing. No instinct tells him what he has to do, and no tradition tells him what he ought to do; sometimes he does not even know what he wishes to do. Instead, he either wishes to do what other people do (conformism) or he does what other people tell him to do (totalitarianism).”

“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.”

“Man is the only animal that laughs and weeps; for he is the only animal that is struck with the difference between what things are, and what they ought to be.”

“Man is the cruelest animal," says Zarathustra. "When gazing at tragedies, bull-fights, crucifixations he hath hitherto felt happier than at any other time on Earth. And when he invented Hell...lo, Hell was his Heaven on Earth"; he could put up with suffering now, by contemplating the eternal punishment of his oppressors in the other world.”

“Man is the only animal for whom his own existence is a problem which he has to solve.”
