“Johannes had once said that violence and cruelty were just a stupid person’s way of making himself felt, because it was easer to use your hands to strike a blow than to use your brain to find a logical and just solution to the problem.”

“Dzieje kultury wykazują, ze głupota jest siostrą bliźniaczą rozumu, ona rośnie najbujniej nie na glebie dziewiczej ignorancji , lecz na gruncie uprawnym siódmym potem doktorów i profesorów. Wielkie absurdy nie są wymyślane przez tych, których rozum krząta się wokół spraw codziennych. Nic dziwnego zatem, że właśnie najintensywniejsi myśliciele bywali producentami największego głupstwa. / The history of culture shows that foolishness is a twin sister of wisdom. It does not flourish on the fields of pure ignorance but on the fields tirelessly plowed by doctors and professors. Great absurdities do not flourish where one is busy with everyday life. No wonder that sometimes most vigorous thinkers come up with utmost stupidities. (Dziennik 1956, XIX, Thursday)”

“Hundreds of wise men cannot make the world a heaven, but one idiot is enough to turn it into a hell.”

“Stupidity and wisdom meet in the same centre of sentiment and resolution, in the suffering of human accidents.”

“Empathy nurtures wisdom. Apathy cultivates ignorance.”

“Incredibly intelligent people always seem odd to those who are not as sharp.”

“Ah! how little knowledge does a man acquire in his life. He gathers it up like water, but like water it runs between his fingers, and yet, if his hands be but wet as though with dew, behold a generation of fools call out, ‘See, he is a wise man!’ Is it not so?”

“Brave? Or stupid?”Roger shrugged. “I’ve never been quite sure where brave stopped and stupid began, myself.”

“There’s a thin line between genius and bottom-barrel stupidness. I hover delicately on a tightrope between the two, wondering where I’ll land if I’ll ever fall.”

“She avoids deep thought like an empty restaurant, not out of stupidity, but a canny resolve to be happy.”

“Jasnah had once defined a fool as a person who ignored information because it disagreed with desired results.”

“To be stupid, and selfish, and to have good health are the three requirements for happiness – though if stupidity is lacking, the others are useless.”

“Silk is a fine, delicate, soft, illuminating, beautiful substance. But you can never rip it! If a man takes this tender silk and attempts to tear it, and cannot tear it, is he in his right mind to say “This silk is fake! I thought it was soft, I thought it was delicate, but look, I cannot even tear it” ? Surely, this man is not in his right mind! The silk is not fake! This silk is 100% real. It’s the man who is stupid!”

“Bizim hepimizin içinde zübüklük olmasa, bizler de birer zübük olmasak, aramızdan böyle zübükler büyüyemezdi. Hepimizde birer parça olan zübüklük birleşip işte başımıza böyle zübükler çıkıyor. Oysa zübüklük bizde, bizim içimizde. Onları biz, kendi zübüklüğümüzden yaratıyoruz. Sonra, kendi zübüklüklerimizin bir tek Zübük’de birleştiğini görünce ona kızıyoruz. Bu zübükler heryerde var, biz zübükler nerde varsak, onlar da orada…”
