“Between the ages of twenty and forty we are engaged in the process of discovering who we are, which involves learning the differences between accidental limitations which it is our duty to outgrow and the necessary limitations of our nature beyond which we cannot trespass with impunity.”

“A child's reading is guided by pleasure, but his pleasure is undifferentiated; he cannot distinguish, for example, between aesthetic pleasure and the pleasures of learning or daydreaming. In adolescence we realize that there are different kinds of pleasure, some of which cannot be enjoyed simultaneously, but we need help from others in defining them. Whether it be a matter of taste in food or taste in literature, the adolescent looks for a mentor in whose authority he can believe. He eats or reads what his mentor recommends and, inevitably, there are occasions when he has to deceive himself a little; he has to pretend that he enjoys olives or War and Peace a little more than he actually does. Between the ages of twenty and forty we are engaged in the process of discovering who we are, which involves learning the difference between accidental limitations which it is our duty to outgrow and the necessary limitations of our nature beyond which we cannot trespass with impunity. Few of us can learn this without making mistakes, without trying to become a little more of a universal man than we are permitted to be. It is during this period that a writer can most easily be led astray by another writer or by some ideology. When someone between twenty and forty says, apropos of a work of art, 'I know what I like,'he is really saying 'I have no taste of my own but accept the taste of my cultural milieu', because, between twenty and forty, the surest sign that a man has a genuine taste of his own is that he is uncertain of it. After forty, if we have not lost our authentic selves altogether, pleasure can again become what it was when we were children, the proper guide to what we should read.”

“We live in oppressive times. We have, as a nation, become our own thought police; but instead of calling the process by which we limit our expression of dissent and wonder ‘censorship,’ we call it ‘concern for commercial viability.”

“I wish you wouldn't say the first thing that comes into your head, Ludo. There is an obvious difference between someone who works within the technical limitations of his time which are beyond his control and someone who accepts without thinking limitations which are entirely within his own power to set aside.”

“It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call "observation" in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call "chance" when they are made by electrons.”

“We have to cease to think, if we refuse to do it in the prison house of language; for we cannot reach further than the doubt which asks whether the limit we see is really a limit.”
