“Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.”

“The acquisition of knowledge always involves the revelation of ignorance - almost is the revelation of ignorance. Our knowledge of the world instructs us first of all that the world is greater than our knowledge of it. To those who rejoice in the abundance and intricacy in Creation, this is a source of joy, as it is to those who rejoice in freedom...To those would-be solvers of "the human problem," who hope for knowledge equal to (capable of controlling) the world, it is a source of unremitting defeat and bewilderment. The evidence is overwhelming that knowledge does not solve "the human problem." Indeed, the evidence overwhelmingly suggests - with Genesis - that knowledge is the problem. Or perhaps we should say instead that all our problems tend to gather under two questions about knowledge: Having the ability and desire to know, how and what should we learn? And, having learned, how and for what should we use what we know? (pg. 183, People, Land, and Community)”

“Neglect of mathematics work injury to all knowledge, since he who is ignorant of it cannot know the other sciences or things of this world. And what is worst, those who are thus ignorant are unable to perceive their own ignorance, and so do not seek a remedy.”

“The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know.”

“No persons are more frequently wrong, than those who will not admit they are wrong.”

“There are those who know and those who don't know. And for every ten thousand who don't know there's only one who knows. That's the miracle of all time--the fact that these millions know so much but don't know this.”
