“Cynical realism—it's the intelligent man's best excuse for doing nothing in an intolerable situation”

“Children are remarkable for their intelligence and ardor, for their curiosity, their intolerance of shams, the clarity and ruthlessness of their vision.”

“Man is an intelligence, not served by, but in servitude to his organs.”

“You never see animals going through the absurd and often horrible fooleries of magic and religion. . . . Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat's meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, quite intelligent enough.”

“Man is so intelligent that he feels impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic.”

“which is better - to be born stupid into an intelligent society or intelligent into an insane one?”

“No, give me the past. It doesn’t change; it’s all there in black and white, and you can get to know about it comfortably and decorously and, above all, privately - by reading. … As reading becomes more and more habitual and widespread, an ever-increasing number of people will discover that books will give them all the pleasures of social life and none of its intolerable tedium.”
