“The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.”

“He can compress the most words into the smallest ideas of any man I ever met.”

“No one can draw more out of things, books included, than he already knows. A man has no ears for that to which experience has given him no access.”

“It is impossible for a man to learn what he thinks he already knows.”

“A warrior considers himself already dead, so there is nothing for him to lose. The worst has already happened to him, therefore he's clear and calm; judging him by his acts or by his words, one would never suspect that he has witnessed everything.”

“Most conscious thought is simply an attempt to claim ‘authorship’ for a choice that has already been made. Our thoughts are just an ongoing attempt to explain what we’ve already decided.”

“I have written this work not to teach men what they do not know, but to remind them of what they already know and is very evident to them, for you will find in most of my words only things which most people know, and concerning which they entertain no doubts. But to the extent that they are well known and their truths revealed to all, so is forgetfulness in relation to them extremely prevalent. … It is possible that the reader will find that he has learned little after having read it that he did not know before. Its benefit is to be derived, rather, through review and persistent study, by which one is reminded of those things which, by nature, he is prone to forget and through which he is caused to take to heart the duty that he tends to overlook.”

“I believe there is one Supreme most perfect being. … I believe He is pleased and delights in the happiness of those He has created; and since without virtue man can have no happiness in this world, I firmly believe He delights to see me virtuous.”

“Western philosophy and science have for the most part been committed to the Simplicity Theory of Truth: the simplest theory that accounts for the data is the true theory. (Theories are simplest which postulate the fewest entities, require the fewest hypotheses, generate predictions by the fewest calculations, etc.) ...If someone believes that the world is made for him to have dominion over and he is made to exploit it, he must believe that he and the world are so made that he can, at least in principle, achieve and maintain dominion over everything. But you can’t put things to use if you don’t know how they work. So he must believe that he can, at least in principle, understand everything. If the world exists for man, it must be usably intelligible, which means it must be simple enough for him to understand. A usable universe is an intelligible universe is a simple universe. ...And so it goes with the philosophy and the science of The Arrogant Eye.”

“If a man would pursue Philosophy, his first task is to throw away conceit. For it is impossible for a man to begin to learn what he has a conceit that he already knows.”
