“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.”
“Charles V. said that a man who knew four languages was worth four men; and Alexander the Great so valued learning, that he used to say he was more indebted to Aristotle for giving him knowledge that, than his father Philip for giving him life.”
“When you see the abyss, and we have looked into it, then what? There isn't much room at the edge -- one person, another, not many. If you are there, others cannot be there. If you are there, you become a protective wall. What happens? You become part of t”
“As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself.”
“Knowledge, a rude unprofitable mass, the mere materials with which wisdom builds, till smoothed and squared and fitted to its place, does but encumber whom it seems to enrich. Knowledge is proud that he has learned so much; wisdom is humble that he knows no more.”
“Since we can't know what knowledge will be most needed in the future, it is senseless to try to teach it in advance. Instead, we should try to turn out people who love learning so much and learn so well that they will be able to learn whatever needs to be learned.”
“Man is distinguished, not only by his reason; but also by this singular passion from other animals... which is a lust of the mind, that by a perseverance of delight in the continual and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.”
“Knowledge, without common sense, says Lee, is folly; without method, it is waste; without kindness, it is fanaticism; without religion, it is death. But with common sense, it is wisdom with method, it is power; with clarity, it is beneficence; with religion, it is virtue, and life, and peace.”
“The use of knowledge in our sex (beside the amusement of solitude) is to moderate the passions and learn to be contented with a small expense, which are the certain effects of a studious life and, it may be, preferable even to that fame which men have engrossed to themselves and will not suffer us to share.”
“The knowledge of an unlearned man is living and luxuriant like a forest, but covered with mosses and lichens and for the most part inaccessible and going to waste; the knowledge of the man of science is like timber collected in yards for public works, which still supports a green sprout here and there, but even this is liable to dry rot.”
“Of a truth, Knowledge is power, but it is a power reined by scruple, having a conscience of what must be and what may be; whereas Ignorance is a blind giant who, let him but wax unbound, would make it a sport to seize the pillars that hold up the long-wrought fabric of human good, and turn all the places of joy as dark as a buried Babylon.”
“We have no organ at all for knowledge, for ''truth'': we ''know'' (or believe or imagine) precisely as much as may be useful in the interest of the human herd, the species: and even what is here called ''usefulness'' is in the end only a belief, something imagined and perhaps precisely that most fatal piece of stupidity by which we shall one day perish.”
“We are in fact convinced that if we are ever to have pure knowledge of anything, we must get rid of the body and contemplate things by themselves with the soul by itself. It seems, to judge from the argument, that the wisdom which we desire and upon which we profess to have set our hearts will be attainable only when we are dead and not in our lifetime.”
“I would have the studies elective. Scholarship is to be created not by compulsion, but by awakening a pure interest in knowledge. The wise instructor accomplishes this by opening to his pupils precisely the attractions the study has for himself. The marking is a system for schools, not for the college; for boys, not for men; and it is an ungracious work to put on a professor.”
“Vague and mysterious forms of speech, and abuse of language, have so long passed for mysteries of science; and hard or misapplied words with little or no meaning have, by prescription, such a right to be mistaken for deep learning and height of speculation, that it will not be easy to persuade either those who speak or those who hear them, that they are but the covers of ignorance and hindrance of true knowledge.”
“''Knowledge is power.'' Rather, knowledge is happiness, because to have knowledge -- broad, deep knowledge -- is to know true ends from false, and lofty things from low. To know the thoughts and deeds that have marked man's progress is to feel the great heartthrobs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.”
“The hunger and thirst for knowledge, the keen delight in the chase, the good humored willingness to admit that the scent was false, the eager desire to get on with the work, the cheerful resolution to go back and begin again, the broad good sense, the unaffected modesty, the imperturbable temper, the gratitude for any little help that was given -- all these will remain in my memory though I cannot paint them for others.”
“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
“There's a theory, one I find persuasive, that the quest for knowledge is, at bottom, the search for the answer to the question: ''Where was I before I was born.'' In the beginning was what? Perhaps, in the beginning, there was a curious room, a room like this one, crammed with wonders; and now the room and all it contains are forbidden you, although it was made just for you, had been prepared for you since time began, and you will spend all your life trying to remember it.”
