“One can bring no greater reproach against a man than to say that he does not set sufficient value upon pleasure, and there is no greater sign of a fool than the thinking that he can tell at once and easily what it is that pleases him. To know this is not easy, and how to extend our knowledge of it is the highest and the most neglected of all arts and branches of education.”

“2454. If any one giveth thee excessive Praises more than can handsomely belong to thee, thou art to think of him, that he taketh thee for vain and credulous, and easy to be deceived, and effectually a Fool.”

“How dangerous is the acquirement of knowledge and how much happier that man is who believes his native town to be the world, than he who aspires to be greater than his nature will allow.”

“You can have no greater sign of confirmed pride than when you think you are humble enough.”

“An idea is a greater monument than a cathedral. And the advance of man's knowledge is a greater miracle than all the sticks turned to snakes or the parting of the waters.”

“Wisdom is, I suppose, the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.”

“You don't need to be told some things. You can sometimes tell more by a man's silence and the set of his head than by what he says.”

“In science men have discovered an activity of the very highest value in which they are no longer, as in art, dependent for progress upon the appearance of continually greater genius, for in science the successors stand upon the shoulders of their predecessors; where one man of supreme genius has invented a method, a thousand lesser men can apply it.”

“You can tell more about a person by what he says about others than you can by what others say about him.”

“Economic man and the Calvinist Christian sing to each other like voices in a fugue. The Calvinist stands alone before an almost merciless God; no human agency can help him; his church is a means to political and social organization rather than a bridge to deity, for no priest can have greater knowledge of the divine way than he himself; no friend can console him — in fact, he should distrust all men; in the same fashion, Economic Man faces a merciless world alone and unaided, his hand against every other's.”
