«People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations.»

«Education at school continues what has been done at home: it crystallizes the optical illusion, consolidates it with book learning, theoretically legitimizes the traditional trash and trains the children to know without understanding and to accept denominations for definitions. Astray in his conceptions, entangled in words, man loses the flair for truth, the taste for nature. What a powerful intellect must you possess, to be suspicious of this moral carbon dioxide and with your head swimming already, to hurl yourself out of it into the fresh air, with which, into the bargain, everyone round is trying to scare you!»

«Baseball is a game where a curve is an optical illusion, a screwball can be a pitch or a person, stealing is legal and you can spit anywhere you like except in the umpire's eye or on the ball.»

«Every reader finds himself. The writer's work is merely a kind of optical instrument that makes it possible for the reader to discern what, without this book, he would perhaps never have seen in himself.»

«A human being is part of a whole, called by us the Universe, a part limited in time and space. He experiences himself, his thoughts and feelings, as something separated from the rest a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty.»
