Quotes & Sayings About Knowledge From Philosophers

Let me whisper my belief, entre nous, that of those eminent philosophers who cry out against parsons the loudest, there are not many who have got their knowledge of the church by going thither often. — William Makepeace Thackeray

Scholars love knowledge.
Philosophers love wisdom.
The most knowledgeable become professors.
The most wise become sages. — Matshona Dhliwayo

Men are not philosophers, but are rather very foolish children, who, by reason of their partiality, see everything in the most absurd manner, and are the victims at all times of the nearest object. There is even no philosopher who is a philosopher at all times. Our experience, our perception is conditioned by the need to acquire in parts and in succession, that is, with every truth a certain falsehood. — Ralph Waldo Emerson

Progress in science and technology is real, but it builds on past truths without rejecting them. Computers don't have to be re-invented in order to keep getting better; innovations expand what they already do. Knowledge accumulates, so it can increase. Scientists and engineers know this, but artists, authors, and philosophers keep trying to start over from ground zero in the humanities. Thus, they don't really progress - they become primitive. — Gene Edward Veith Jr.

Even those who have desired to work out a completely positive philosophy have been philosophers only to the extent that, at the same time, they have refused the right to install themselves in absolute knowledge. They taught not this knowledge, but its becoming in us, not the absolute but, at most, our absolute relation to it, as Kierkegaard said. What makes a philosopher is the movement which leads back without ceasing from knowledge to ignorance, from ignorance to knowledge, and a kind of rest in this movement. — Maurice Merleau Ponty

[T]he whole undertaking of philosophical inquiry requires a prior understanding of the conceptual system in which the undertaking is set. That is an empirical job for cognitive science and cognitive semantics ... Unless this job is done, we will not know whether the answers philosophers give to their questions are a function of the conceptualization built into the questions themselves. — George Lakoff

No one really knew the sciences except the Lord Robert, Bishop of Lincoln, by reason of his length of life and experience, as well as of his studiousness and zeal. He knew mathematics and perspective, and there was nothing which he was unable to know; and at the same time he was sufficiently acquainted with languages to be able to understand the saints and the philosophers and the wise men of antiquity but his knowledge of languages was not such as to enable him to effect translations until the latter portion of his life ... — Roger Bacon

some Japanese philosophers have been eager to graft the newly introduced discipline of western academic philosophy onto its premodern Japanese antecedents. The conflict with traditional values proposed a whole host of new questions: Can one articulate an original yet comprehensive epistemology that would give western empiricism and logic an appropriate place but subordinate it to a dominant "Asian" basis for thought and values? Can one develop a viable ethics that places agency in a socially interdependent, rather than isolated and discrete, individual? Can one construct an interpretation of artistry based in a mode of responsiveness that is also the ground for knowledge and moral conduct? Can one envision a political theory of the state that allows for personal expression without assuming a radical individualism? Along with these fundamental issues, a great deal of attention was devoted to a still more basic question: What is culture and what affect does it have on philosophizing? — James W. Heisig

In saying that the truth is both said and not said by the philosopher (said and not said in the form of stammering), Aristotle was still close to the methods of interpretation used by grammarians in their commentaries on the poets. Symbolic or allegorical methods pointing out what was deliberately hidden by Homer behind the figure of Nestor or Ulysses.

But there is a difference however - and a crucial one - which is that for Aristotle the equivocation of the said and the not-said, this distance without gap which means that the truth is both hidden and present in the philosopher's words, this light that is shadow, is not the effect of an oracular kind of intentional secret or prudent reserve. If philosophers do not speak the truth, this is not because their indulgence wishes to protect men from its terrible face; it is because they lack a certain knowledge (savoir). — Michel Foucault

If Socrates was alive today he would say : I know that I know everything. That's what contemporary philosophers do. — Ljupka Cvetanova

The Prayer of Examine produces within us the priceless grace of self-knowledge. I wish I could adequately explain to you how great a grace this truly is. Unfortunately, contemporary men and women simply do not value self-knowledge in the same way that all preceding generations have. For us technocratic knowledge reigns supreme. Even when we pursue self-knowledge, we all too often reduce it to a hedonistic search for personal peace and prosperity. How poor we are! Even the pagan philosophers were wiser than this generation. They knew that an unexamined life was not worth living. — Richard J. Foster

An Islamic university ... structure is different from a Western University; [its] conception of what constitutes knowledge is different from what Western philosophers set forth as knowledge; [its] aims and aspirations are different from Western conceptions. The purpose of higher education is not, like in the West, to produce the complete citizen, but rather, as in Islam, to produce the complete man, or the universal man ... A Muslim scholar is a man who is not a specialist in any one branch of knowledge but is universal in his outlook and is authoritative in several branches of related knowledge. — Syed Muhammad Naquib Al-Attas

Philosophy treats of physics where a more careful knowledge is required because the problems which come under this head are numerous ... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers. — Marcus Vitruvius Pollio

Philosophers of science constantly discuss theories and representation of reality, but say almost nothing about experiment, technology, or the use of knowledge to alter the world. This is odd, because 'experimental method' used to be just another name for scientific method ... I hope [to] initiate a Back-to-Bacon movement, in which we attend more seriously to experimental science. Experimentation has a life of its own. — Ian Hacking

To the philosophers of India, however, Relativity is no new discovery, just as the concept of light years is no matter for astonishment to people used to thinking of time in millions of kalpas, (A kalpa is about 4,320,000 years). The fact that the wise men of India have not been concerned with technological applications of this knowledge arises from the circumstance that technology is but one of innumerable ways of applying it. — Alan W. Watts

I had a dream about you. You were trying to understand the nature of nature, and I was trying to understand understanding. I thought we looked like philosophers, but your mother thought we looked like porn stars. Yes, we were naked, and yes, we were having sex, but isn't that the best way to really go about knowing knowledge? Anyway, if your mother wasn't happy with our teaching methods, she shouldn't have signed up for our class. — Jarod Kintz

Contemporary philosophers have exercised themselves with the problem of our knowledge of other minds. Enmeshed in the dogma of the ghost in the machine, they have found it impossible to discover any logically satisfactory evidence warranting one person in believing that there exist minds other than his own. I can witness what your body does, but I cannot witness what your mind does, and my pretensions to infer from what your body does to what your mind does all collapse, since the premises for such inferences are either inadequate or unknowable. — Gilbert Ryle

It is not in the books of the Philosophers, but in the religious symbolism of the Ancients, that we must look for the footprints of Science, and re-discover the Mysteries of Knowledge. — Albert Pike

You ask: What is it that philosophers have called qualitative states? I answer, only half in jest: As Louis Armstrong said when asked what jazz is, 'If you got to ask, you ain't never gonna get to know.' — Ned Block

The nature of God is something that is of serious interest to believers, to theologians, and to philosophers. And yet we can't come to the nature of God, unless we also have some knowledge of the nature of the universe as having come from God. — George Coyne

I became a virtuoso of deceit. It wasn't pleasure I was after, it was knowledge. I consulted the strictest moralists to learn how to appear, philosophers to find out what to think and novelists to see what I could get away with. — Christopher Hampton

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics. — Max Born

Indeed, at hearing the news that 'the old god is dead', we philosophers and 'free spirits' feel illuminated by a new dawn; our heart overflows with gratitude, amazement, forebodings, expectation - finally the horizon seems clear again, even if not bright; finally our ships may set out again, set out to face any danger; every daring of the lover of knowledge is allowed again; the sea, our sea, lies open again; maybe there has never been such an 'open sea'. — Friedrich Nietzsche

The phaenomena afforded by trades, are a part of the history of nature, and therefore may both challenge the naturalist's curiosity and add to his knowledge, Nor will it suffice to justify learned men in the neglect and contempt of this part of natural history, that the men, from whom it must be learned, are illiterate mechanicks ... is indeed childish, and too unworthy of a philosopher, to be worthy of an honest answer. — Robert Boyle

I care not for the girdings of superstition, for superstition is the bitter enemy of knowledge & true morality. Yes; it has come to this! Men who openly confess that they can form no idea of God, & only know him through created things, of which they know not the causes, can unblushingly accuse philosophers of Atheism. — Baruch Spinoza

The knowledge that is suited to our situation and powers, the whole compass of moral, natural, and mathematical science, was neglected by the new Platonists; whilst they exhausted their strength in the verbal disputes of metaphysics, attempted to explore the secrets of the invisible world, and studied to reconcile Aristotle with Plato, on subjects of which both these philosophers were as ignorant as the rest of mankind. — Edward Gibbon

It seems to me that philosophers should be more relaxed about whether or not some form of materialism is true. — Tyler Burge

Intuition does not in itself amount to knowledge, yet cannot be disregarded by philosophers and psychologists. — Corliss Lamont

When philosophers use a word
"knowledge," "being," "object," "I," "proposition," "name"
and try to grasp the essence of the thing, one must always ask oneself: is the word ever actually used in this way in the language-game which is its original home?
What we do is to bring words back from their metaphysical to their everyday use. — Ludwig Wittgenstein

Linnaeus's last lesson, of which he himself was unaware, was that professorships kill philosophers. Oh, I'm vain enough to want my burgeoning Flora Japonica to be published one day
as a votive offering to human knowledge
but a seat at Uppsala, or Leiden, or Cambridge, holds no allure. My heart is the East's in this lifetime. This is my third year in Nagasaki, and I have work enough for another three, or six. During the court embassy I can see landscapes no European botanist ever saw. My seminarians are keen young men
with one young woman
and visiting scholars bring me specimens from all over the empire. — David Mitchell

The finest SF comes to grips with life's mysteries, with our resentments against our own natures and our limited societies. It does so by asking basic questions in the artful, liberating way that is unique to this form of writing. Echoes of it are found in other forms of fiction - in the novel of ideas, in the historical novel, in the writings of the great philosophers and scientists; but the best SF does this all more searchingly, by taking what is in most people only a moment of wonder and rebellion against the arbitrariness of existence and making of it an art enriched by knowledge and possibility, expressing our deepest human longing to penetrate into the dark heart of the unknown. — George Zebrowski

Confronted with such a variety most philosophers try to establish one approach to the exclusion of all others. As far as they are concerned there can only be one true way- and they want to find it. Thus normative philosophers argue that knowledge is a result of the application of certain rules, they propose rules which in their opinion constitute knowledge and reject what clashes with them. — Paul Feyerabend

Your remarks upon chemical notation with the variety of systems which have arisen, &c., &c., had almost stirred me up to regret publicly that such hindrances to the progress of science should exist. I cannot help thinking it a most unfortunate thing that men who as experimentalists & philosophers are the most fitted to advance the general cause of science & knowledge should by promulgation of their own theoretical views under the form of nomenclature, notation, or scale, actually retard its progress. — Michael Faraday

Scientists and philosophers tend to treat knowledge, imagination and love as if they were all very separate parts of human nature. But when it comes to children, all three are deeply entwined. Children learn the truth by imagining all the ways the world could be, and testing those possibilities. — Alison Gopnik

Epistemologists should be concerned with knowledge and justification and so on, not our concepts of them; philosophers of mind should be concerned with various features of our mental life and the large-scale structure of the mind, not our concepts of mind, or consciousness, or anything else — Hilary Kornblith

Conclusions that philosophers first establish by way of torturous reasoning have a way, over time, of leaking into shared knowledge. — Rebecca Goldstein

The scientific revolution was part of a wider intellectual revolution, the Enlightenment, which also brought progress in other fields, especially moral and political philosophy, and in the institutions of society. Unfortunately, the term 'the Enlightenment' is used by historians and philosophers to denote a variety of different trends, some of them violently opposed to each other. What I mean by it will emerge here as we go along. It is one of several aspects of 'the beginning of infinity', and is a theme of this book. But one thing that all conceptions of the Enlightenment agree on is that it was a rebellion, and specifically a rebellion against authority in regard to knowledge. — David Deutsch

Some philosophers are drawn to the subject [of philosophy] via their interest in the nature and structure of the world external to us. Others are drawn to it by an interest in the capacities that make humans distinctive in the world. I am a philosopher of the latter sort. My work thus far has been clustered around the nexus of knowledge, communication, and human action. — Jason Stanley

The criers of the Mysteries speak again, bidding all men welcome to the House of Light. The great institution of materiality has failed. The false civilization built by man has turned, and like the monster of Frankenstein, is destroying its creator. Religion wanders aimlessly in the maze of theological speculation. Science batters itself impotently against the barriers of the unknown. Only transcendental philosophy knows the path. Only the illumined reason can carry the understanding part of man upward to the light. Only philosophy can teach man to be born well, to live well, to die well, and in perfect measure be born again. Into this band of the elect
those who have chosen the life of knowledge, of virtue, and of utility
the philosophers of the ages invite YOU. — Manly P. Hall

Architects should be educated, skillful with the pencil, instructed in geometry, know much history, have followed the philosophers with attention, understand music, have some knowledge of medicine, know the opinions of the jurists, and be acquainted with astronomy and the theory of the heavens — Marcus Vitruvius Pollio

He remembers the philosophers dead with detail, and how they honed their trade into the grave for the sake of their livelihoods. Incapable of audacity, they pleasured themselves with a maze constructed of nothing but dead-ends. They were so petrified they might happen upon the truth, might come to know something for certain, that they deployed some of their best minds to obliterate it, scattering its shards into infinity. But they were only trying to keep the dream alive, after all, fighting to keep the questions outnumbering the answers, picking away at the odd dropped stitch in an otherwise ever-tightening blanket of sacrosanct precision. They fought hard, if unwittingly, against the encroaching dullness of complete knowledge, but ultimately paid the price of becoming as dull as their enemy - at least the chemical truths of literature sometimes bothered to wear a suit and tie. — Gary J. Shipley

To test a perfect theory with imperfect instruments did not impress the Greek philosophers as a valid way to gain knowledge. — Isaac Asimov

Einstein's results again turned the tables and now very few philosophers or scientists still think that scientific knowledge is, or can be, proven knowledge. — Imre Lakatos

The motive that impels modern reason to know must be described as the desire to conquer and dominate. For the Greek philosophers and the Fathers of the church, knowing meant something different: it meant knowing in wonder. By knowing or perceiving one participates in the life of the other. Here knowing does not transform the counterpart into the property of the knower; the knower does not appropriate what he knows. On the contrary, he is transformed through sympathy, becoming a participant in what he perceives. — Jurgen Moltmann

Mathematicians have sought knowledge in figures, Philosophers in systems, Logicians in subtleties, and Metaphysicians in sounds. It is not in any nor in all of these. He that studies only men, will get the body of knowledge without the soul, and he that studies only books, the soul without the body. — Charles Caleb Colton

Debates about the imagination and its role in human knowledge go back in the West to ancient Greece around the secrets and enigmas of the revealed "symbol" and its relationship to the more plodding ways of reason and rational knowledge. The most recent chapter of that larger conversation goes back to the eighteenth century and what we now call the Romantic movement. The poets and philosophers of the latter asked: What is the imagination? Is it simply a spinner of fantasies? Or can it also become a "window" of revealed truths from some other deeper part of the soul or world? Or, better yet, like some secret two-way mirror in a modern-day police station, is the imagination both, depending on whether one is looking at or through its reflecting surface, that is, depending on which side of it one is standing? Can one stand on both sides? — Whitley Strieber

Therefore, if we would listen to the voice of God15 with due reverence, the soul must stand upright, and not lean on the affections of sense for support. As the prophet Habakkuk says of himself, "I will stand upon my watch, and fix my step upon the munition, and I will behold to see what may be said to me."16 To stand upon the watch is to cast off all desires; to fix the step, is to cease from reflections of sense, that I may behold and understand what God will speak to me. Thus out of this night springs first the knowledge of one's self, and on that, as on a foundation, is built up the knowledge of God. "Let me know myself," says St. Augustine, "and I shall then know Thee, O my God," for, as the philosophers say, one extreme is known by another. — San Juan De La Cruz

Symbols and emblems were everywhere. Buildings and pictures were designed to be read like books. Everything stood for something else; if you had the right dictionary, you could read Nature itself. It was hardly surprising to find philosophers using the symbolism of their time to interpret knowledge that came from a mysterious source. — Philip Pullman

The fact that these scientific theories have a fine track record of successful prediction and explanation speaks for itself. (Which is not to say that I don't directly discuss the work of those philosophers who would disagree.) But even if we grant this, many will argue that scientific knowledge in humans, and, indeed, reflective knowledge in general, is quite different in kind from the knowledge we see in other animals. — Hilary Kornblith

The natural scientists of the previous age knew less than we do and believed they were very close to the goal: we have taken very great steps in its direction and now discover we are still very far away from it. With the most rational philosophers an increase in their knowledge is always attended by an increased conviction of their ignorance. — Georg C. Lichtenberg

It is certain that the labors of these early workers in the field of natural knowledge were brought to a standstill by the decay and disruption of the Roman Empire, the consequent disorganisation of society, and the diversion of men's thoughts from sublunary matters to the problems of the supernatural world suggested by Christian dogma in the Middle Ages. And, notwithstanding sporadic attempts to recall men to the investigation of nature, here and there, it was not until the fifteenth and sixteenth centuries that physical science made a new start, founding itself, at first, altogether upon that which had been done by the Greeks. Indeed, it must be admitted that the men of the Renaissance, though standing on the shoulders of the old philosophers, were a long time before they saw as much as their forerunners had done. — Thomas Henry Huxley

Demetrius the grammarian finding in the temple of Delphos a knot of philosophers set chatting together, said to them, "Either I am much deceived,
or by your cheerful and pleasant countenances, you are engaged in no very deep discourse." To which one of them, Heracleon the Megarean, replied: " 'Tis for such as are puzzled about inquiring whether the future tense of the verb Ballo be spelt with a
double L, or that hunt after the derivation of the comparatives Cheirou and Beltiou, and the superlatives Cheiriotou and Beliotou, to knit their brows whilst discoursing of their science; but as to philosophical discourses, they always divert and cheer up those that entertain them, and never deject them or make them sad. — Michel De Montaigne

I would simply ask why so many critics, so many writers, so many philosophers take such satisfaction in professing that the experience of a work of art is ineffable, that it escapes by definition all rational understanding; why are they so eager to concede without a struggle the defeat of knowledge; and where does their irrepressible need to belittle rational understanding come from, this rage to affirm the irreducibility of the work of art, or, to use a more suitable word, its transcendence. — Pierre Bourdieu

Many modern artists, philosophers, and theologians reject the knowledge of the past. Thus they must continually start over again from ground zero, their vision restricted to their own narrow perspectives, making themselves artificially primitive. — Gene Edward Veith Jr.

IN THE THEOPHANY, TECCAM writes of secrets, calling them painful treasures of the mind. He explains that what most people think of as secrets are really nothing of the sort. Mysteries, for example, are not secrets. Neither are little-known facts or forgotten truths. A secret, Teccam explains, is true knowledge actively concealed. Philosophers — Patrick Rothfuss

Socrates ... is the first philosopher of life [Lebensphilosoph], ... Thinking serves life, while among all previous philosophers life had served thought and knowledge ... Thus Socratic philosophy is absolutely practical: it is hostile to all knowledge unconnected to ethical implications. — Friedrich Nietzsche

Was not Hypatia the greatest philosopher of Alexandria, and a true martyr to the old values of learning? She was torn to pieces by a mob of incensed Christians not because she was a woman, but because her learning was so profound, her skills at dialectic so extensive that she reduced all who queried her to embarrassed silence. They could not argue with her, so they murdered her. — Iain Pears

In recent philosophy there has been a growing awareness of the gap between the abstract principles proposed by philosophers and the ways in which people actually think. The kind of rationality admired in the theory of knowledge is idealization. In the real world people have to act on beliefs often based on fragmentary and unreliable evidence. — Jonathan Glover

Today secular philosophers call that kind of divine invocation God of the gaps-which comes in handy, because there has never been a shortage of gaps in people's knowledge. — Neil DeGrasse Tyson

In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: Did the universe have a beginning? However, in the nineteenth and twentieth centuries, science became too technical and mathematical for the philosophers, or anyone else except a few specialists. Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, "The sole remaining task for philosophy is the analysis of language." What a comedown from the great tradition of philosophy from Aristotle to Kant! — Stephen Hawking

What we encounter in works of art and philosophy are objective versions of our own pains and struggles, evoked and defined in sound, language or image. Artists and philosophers not only show us what we have felt, they present our experiences more poignantly and intelligently than we have been able; they give shape to aspects of our lives that we recognise as our own, yet could never have understood so clearly on our own. They explain our condition to us, and thereby help us to be less lonely with, and confused by it. — Alain De Botton
