Knowledge Quotes

“Our American past always speaks to us with two voices: the voice of the past, and the voice of the present. We are always asking two quite different questions. Historians reading the words of John Winthrop usually ask, What did they mean to him? Citizens ask, What do they mean to us? Historians are trained to seek the original meaning; all of us want to know the present meaning.”

“It is they [men of science] who hold the secret of the mysterious property of the mind by which error ministers to truth, and truth slowly but irrevocably prevails. Theirs is the logic of discovery, the demonstration of the advance of knowledge and the development of ideas, which as the earthly wants and passions of men remain almost unchanged, are the charter of progress, and the vital spark in history.”

“If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience.”

“An important verity about knowledge is that the brain works most effectively with consciously retained information. We more easily remember what we want to recall later. When we feed our fourteen billion brain cells with information that will enrich us and help others, we are really learning to Think Big.”

“People don't want to think. And the deeper they get into trouble, the less they want to think. But by some sort of instinct, they feel that they ought to and it makes them feel guilty. So they'll bless and follow anyone who gives them a justification for not thinking. Anyone who makes a virtue - a highly intellectual virtue - out of what they know to be their sin, their weakness and their guilt.”

“Things and men have always a certain sense, a certain side by which they must be got hold of if one wants to obtain a solid grasp and a perfect command.”

“Knox was engaged in a theological discussion with scientist John Scott Haldane. 'In a universe containing millions of planets,' reasoned Haldane, 'is it not inevitable that life should appear on at least one of them?' 'Sir,' replied Knox, 'if Scotland Yard found a body in your cabin trunk, would you tell them: 'There are millions of trunks in the world; surely one of them must contain a body? I think the would still want to know who put it there'.”

“Wonder [admiratio astonishment, marvel] is a kind of desire for knowledge. The situation arises when one sees an effect and does not know its cause, or when the cause of the particular effect is one that exceeds his power of understanding. Hence, wonder is a cause of pleasure insofar as there is annexed the hope of attaining understanding of that which one wants to know. ... For desire is especially aroused by the awareness of ignorance, and consequently a man takes the greatest pleasure in those things which he discovers for himself or learns from the ground up.”

“Nobody spends somebody else's money as carefully as he spends his own. Nobody uses somebody else's resources as carefully as he uses his own. So if you want efficiency and effectiveness, if you want knowledge to be properly utilized, you have to do it through the means of private property.”

“For a person to build a rich and rewarding life for himself, there are certain qualities and bits of knowledge that he needs to acquire. But there are also things — harmful attitudes, superstitions, emotions — that he needs to chip away. A person needs to chip away everything that doesn't look like the person he or she most wants to become.”

“And your doubt can become a good quality if you train it. It must become knowing, it must become criticism. Ask it, whenever it wants to spoil something for you, why something is ugly, demand proofs from it, test it, and you will find it perhaps bewildered and embarrassed, perhaps also protesting. But don't give in, insist on arguments, and act in this way, attentive and persistent, every single time, and the day will come when, instead of being a destroyer, it will become one of your best workers-perhaps the most intelligent of all the ones that are building your life.”

“The disorganisers are those who want to level everything: property, comforts, the price of commodities, the various services rendered to the State... who want the workmen in the camp to receive the salary of the legislator... who want to level even talents, knowledge, the virtues, because they themselves have none of these things.”
