“Conceive the condition of the human mind if all propositions whatsoever were self-evident except one, which was to become self-evident at the close of a summer’s day, but in the meantime might be the subject of question, of hypothesis, of debate. Art and philosophy, literature and science, would fasten like bees on that one proposition which had the honey of probability in it, and be the more eager because their enjoyment would end with sunset. Our impulses, our spiritual activities, no more adjust themselves to the idea of their future nullity, than the beating of our heart, or the irritability of our muscles.”

“Moreover, the attitude that one ought to believe such and such a proposition, independently of the question whether there is evidence in its favor, is an attitude which produces hostility to evidence and causes us to close our minds to every fact that does not suit our prejudices.”

“These are facts which, with the self-evident proposition that no being can create another being superior to itself, smashes your silly hypothesis to nothing.”

“What makes us exceptional, what makes us America is our allegiance to an idea articulated in a declaration made more than two centuries ago. We hold these truths to be self-evident, that all men are created equal.”

“Our culture tends "to regard the mere energy of impulse as being in every mental and moral way equivalent and even superior to defined intention." Instead we should consider "an idea that once was salient in western culture: the idea of "making a life", by which was meant conceiving human existence, one's own or another's, as if it were a work of art upon which one might pass judgment.... This desire to fashion, to shape, a self and a life has all but gone from a contemporary culture whose emphasis, paradoxically enough, is so much on self.”

“If our subject persuades himself to believe contrary to the evidence in order to evade, somehow, the unpleasant truth to which he has already seen that the evidence points, then and only then is he clearly a self-deceiver.”
