“Proof’ is the hallmark of religion.”

“Science is not about making predictions or performing experiments. Science is about explaining.”

“In ancient times people weren’t just male or female, but one of three types: male/male, male/female, or female/female. In other words, each person was made out of the components of two people. Everyone was happy with this arrangement and never really gave it much thought. But then God took a knife and cut everybody in half, right down the middle. So after that the world was divided just into male and female, the upshot being that people spend their time running around trying to locate their missing other half.”

“In order to disprove the assertion that all crows are black, one white crow is sufficient.”

“My main reason for scepticism about the Huxley/Sagan theory is that the human brain is demonstrably eager to see faces in random patterns, as we know from scientific evidence, on top of the numerous legends about faces of Jesus, or the Virgin Mary, or Mother Teresa, being seen on slices of toast, or pizzas, or patches of damp on a wall. This eagerness is enhanced if the pattern departs from randomness in the specific direction of being symmetrical.”

“The idea that all souls are mortal is the only notion surely terminating love and all its forms.”

“Whereas a novice makes moves until he gets checkmated (proof), a Grand Master realizes 20 moves in advance that it’s futile to continue playing (conceptualizing).”

“The ultimate story of success: When a nobody, who has never once in his entire life known the feeling of being remembered or respected, suddenly snaps and becomes a world dictator. On one hand it sounds just, but on the other, it illustrates the reason why a prosperity message has and needs its limitations.”

“A wonderful area for speculative academic work is the unknowable. These days religious subjects are in disfavor, but there are still plenty of good topics. The nature of consciousness, the workings of the brain, the origin of aggression, the origin of language, the origin of life on earth, SETI and life on other worlds…this is all great stuff. Wonderful stuff. You can argue it interminably. But it can’t be contradicted, because nobody knows the answer to any of these topics.”

“You cannot go on ‘explaining away’ for ever: you will find that you have explained explanation itself away. You cannot go on ‘seeing through’ things for ever. The whole point of seeing through something is to see something through it.”

“Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.”

“If it’s true what is said, that only the wise discover the wise, then it must also be true that the lone wolf symbolizes either the biggest fool on the planet or the biggest Einstein on the planet.”

“BERENGER: And you consider all this natural? 

DUDARD: What could be more natural than a rhinoceros? 

BERENGER: Yes, but for a man to turn into a rhinoceros is abnormal beyond question. 

DUDARD: Well, of course, that’s a matter of opinion … 

BERENGER: It is beyond question, absolutely beyond question! 
DUDARD: You seem very sure of yourself. Who can say where the normal stops and the abnormal begins? Can you personally define these conceptions of normality and abnormality? Nobody has solved this problem yet, either medically or philosophically. You ought to know that. 

BERENGER: The problem may not be resolved philosophically — but in practice it’s simple. They may prove there’s no such thing as movement … and then you start walking … [he starts walking up and down the room] … and you go on walking, and you say to yourself, like Galileo, ‘E pur si muove’ … 

DUDARD: You’re getting things all mixed up! Don’t confuse the issue. In Galileo’s case it was the opposite: theoretic and scientific thought proving itself superior to mass opinion and dogmatism. 

BERENGER: [quite lost] What does all that mean? Mass opinion, dogmatism — they’re just words! I may be mixing everything up in my head but you’re losing yours. You don’t know what’s normal and what isn’t any more. I couldn’t care less about Galileo … I don’t give a damn about Galileo. 

DUDARD: You brought him up in the first place and raised the whole question, saying that practice always had the last word. Maybe it does, but only when it proceeds from theory! The history of thought and science proves that. BERENGER: [more and more furious] It doesn’t prove anything of the sort! It’s all gibberish, utter lunacy! 

DUDARD: There again we need to define exactly what we mean by lunacy … 

BERENGER: Lunacy is lunacy and that’s all there is to it! Everybody knows what lunacy is. And what about the rhinoceroses — are they practice or are they theory?”

“Life had stepped into the place of theory and something quite different would work itself out in his mind.”
