“Indeed it may be said with some confidence that the average man never really thinks from end to end of his life. There are moments when his cogitations are relatively more respectable than usual, but even at their climaxes they never reach anything properly describable as the level of serious thought. The mental activity of such people is only a mouthing of clichés. What they mistake for thought is simply a repetition of what they have heard. My guess is that well over eighty per cent. of the human race goes through life without having a single original thought. That is to say, they never think anything that has not been thought before and by thousands.”

“It may indeed be said that the word is never a more splendid mystery than when it travels in a man's mind from thought to conscience and back again to thought.”

“I saw the patterns of history and thought that a human might be eighty per cent chemicals, eighteen per cent his past, and two per cent feeling, creatures of habit. Which makes psychiatrists really pharmacists who have to listen longer.”

“A book can never be anything more than the impress of its author's thoughts; and the value of these will lie either in the matter about which he has thought, or in the form which his thoughts take, in other words, what it is that he has thought about it.”

“There were times when [he] allowed himself to see clearly that he would end his working life, that was to say, his conscious thinking life, in this task, that all his thoughts would have been another man's thoughts, all his work another man's work. And then he thought it did not perhaps matter so greatly... It was a pleasant subordination, if he was a subordinate.”

“Not his real name, darling, but my own name for him. I never thought it could be like this. I never thought one could be so close, and yet so different to a single human being. He is everything I've never been, and yet I love him more than any person or anything I've ever known.”
