Knowledge Quotes

“There are for man only two principles available for a mental grasp of reality, namely, those of teleology and causality. What cannot be brought under either of these categories is absolutely hidden to the human mind. An event not open to an interpretation by one of these two principles is for man inconceivable and mysterious. Change can be conceived as the outcome either of the operation of mechanistic causality or of purposeful behavior; for the human mind there is no third way available.”

“Knowledge has two extremes. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great minds, who, having run through all that men can know, find they know nothing, and come back again to that same natural ignorance from which they set out; this is a learned ignorance which is conscious of itself.”

“I am not of the opinion generally entertained in this country [England], that man lives by Greek and Latin alone; that is, by knowing a great many words of two dead languages, which nobody living knows perfectly, and which are of no use in the common intercourse of life. Useful knowledge, in my opinion, consists of modern languages, history, and geography; some Latin may be thrown into the bargain, in compliance with custom, and for closet amusement.”

“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.”

“There are two ways of spreading light: to be the candle or the mirror that reflects it.”

“All schools, all colleges, have two great functions: to confer, and to conceal, valuable knowledge. The theological knowledge which they conceal cannot justly be regarded as less valuable than that which they reveal. That is, when a man is buying a basket of strawberries it can profit him to know that the bottom half of it is rotten.”

“Economic development over the past two centuries has taken most of humanity from lives that were brutal, ignorant and short, to personal health and security, material comfort and knowledge that were unknown to the elites of the wealthiest and most powerful societies in earlier times.”

“Whoever wishes to acquire a deep acquaintance with Nature must observe that there are analogies which connect whole branches of science in a parallel manner, and enable us to infer of one class of phenomena what we know of another. It has thus happened on several occasions that the discovery of an unsuspected analogy between two branches of knowledge has been the starting point for a rapid course of discovery.”

“A discovery must be, by definition, at variance with existing knowledge. During my lifetime, I made two. Both were rejected offhand by the popes of the field. Had I predicted these discoveries in my applications, and had those authorities been my judges, it is evident what their decisions would have been.”

“By this we may understand, there be two sorts of knowledge, whereof the one is nothing else but sense, or knowledge original (as I have said at the beginning of the second chapter), and remembrance of the same; the other is called science or knowledge of the truth of propositions, and how things are called, and is derived from understanding.”

“It is better to have a few forms well known than to teach a little about many hundred species. Better a dozen specimens thoroughly studied as the result of the first year's work, than to have two thousand dollars' worth of shells and corals bought from a curiosity-shop. The dozen animals would be your own.”

“Our knowledge springs from two fundamental sources of the mind; the first is the capacity of receiving representations (receptivity for impressions), the second is the power of knowing an object through these representations (spontaneity [in the production] of concepts).”

“[At the end of the story, its main character, Tom] is now a great man of science, and can plan railroads, and steam-engines, and electric telegraphs, and rifled guns, and so forth; and knows everything about everything, except why a hen's egg don't turn into a crocodile, and two or three other little things that no one will know till the coming of the Cocqcigrues.”

“During the last two centuries and a half, physical knowledge has been gradually made to rest upon a basis which it had not before. It has become mathematical. The question now is, not whether this or that hypothesis is better or worse to the pure thought, but whether it accords with observed phenomena in those consequences which can be shown necessarily to follow from it, if it be true”

“Neither theological knowledge nor social action alone is enough to keep us in love with Christ unless both are proceeded by a personal encounter with Him. Theological insights are gained not only from between two covers of a book, but from two bent knees before an altar. The Holy Hour becomes like an oxygen tank to revive the breath of the Holy Spirit in the midst of the foul and fetid atmosphere of the world”

“A pin lies in wait for every bubble. And when the two eventually meet, a new wave of investors learns some very old lessons: First, many in Wall Street (a community in which quality control is not prized) will sell investors anything they will buy. Second, speculation is most dangerous when it looks easiest.”

“Knowing has two poles, and they are always poles apart: carnal knowing, the laying on of hands, the hanging of the fact by head or heels, the measurement of mass and motion, the calibration of brutal blows, the counting of supplies; and spiritual knowing, invisibly felt by the inside self, who is but a fought-over field of distraction, a stage where we recite the monotonous monologue that is our life, a knowing governed by internal tides, by intimations, motives, resolutions, by temptations, secrecy, shame, and pride.”

“Our society cannot afford a two-tiered system in which the affluent have access to superior education, while everyone else is subjected to a dull and incoherent classroom experience. Academic excellence, educational equity, and fairness demand a strong foundation of knowledge for all learners.”
