“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.”

“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.”

“Believing a given proposition is a matter of believing that it faithfully represents some state of the world, and this fact yields some immediate insights into the standards by which our beliefs should function. In particular, it reveals why we cannot help but value evidence and demand that propositions about the world logically cohere.”

“Our challenge as introverts is to adopt the attitude, based on the introversion assumption, that your need to retreat requires no explanation—it is self-evident.”

“Any facts facing us is not as important as our attitude towards it, for that determines our success or failures...”

“Our life is composed of events and states of mind. How ewe appraise our life from our deathbed will be predicated not only on what came to us in life but how we lived with it. It will not be simply illness or health, riches or poverty, good luck or bad, which ultimately define whether we believe we have had a good life or not, but the quality of our relationship to these situations: the attitudes of our states of mind.
