30 Quotes on Truth and Knowledge

"No more useful inquiry can be proposed than that which seeks to determine the nature and the scope of human knowledge. ... This investigation should be undertaken once at least in his life by anyone who has the slightest regard for truth, since in pursuing it the true instruments of knowledge and the whole method of inquiry come to light. But nothing seems to me more futile than the conduct of those who boldly dispute about the secrets of nature ... without yet having ever asked even whether human reason is adequate to the solution of these problems."

— René Descartes

"We both are, and know that we are, and delight in our being, and our knowledge of it. Moreover, in these three things no true-seeming illusion disturbs us; for we do not come into contact with these by some bodily sense, as we perceive the things outside of us of all which sensible objects it is the images resembling them, but not themselves which we perceive in the mind and hold in the memory, and which excite us to desire the objects. But, without any delusive representation of images or phantasms, I am most certain that I am, and that I know and delight in this. In respect of these truths, I am not at all afraid of the arguments of the Academicians, who say, What if you are deceived? For if I am deceived, I am. For he who is not, cannot be deceived; and if I am deceived, by this same token I am. And since I am if I am deceived, how am I deceived in believing that I am? for it is certain that I am if I am deceived. Since, therefore, I, the person deceived, should be, even if I were deceived, certainly I am not deceived in this knowledge that I am. And, consequently, neither am I deceived in knowing that I know. For, as I know that I am, so I know this also, that I know. And when I love these two things, I add to them a certain third thing, namely, my love, which is of equal moment. For neither am I deceived in this, that I love, since in those things which I love I am not deceived; though even if these were false, it would still be true that I loved false things. For how could I justly be blamed and prohibited from loving false things, if it were false that I loved them? But, since they are true and real, who doubts that when they are loved, the love of them is itself true and real? Further, as there is no one who does not wish to be happy, so there is no one who does not wish to be . For how can he be happy, if he is nothing?"

— Augustine of Hippo

"In this present life, I reckon that we make the nearest approach to knowledge when we have the least possible concern or interest in the body, and are not saturated with the bodily nature, but remain pure until the hour when God himself is pleased to release us. And then the foolishness of the body will be cleared away and we shall be pure and hold converse with othe pure souls, and know of ourselves the clear light everywhere; and this is surely the light of truth. For no impure thing is allowed to approach the pure. These are the sort of words, Simmias, which the true lovers of wisdom cannot help saying to one another, and thinking."

"That condition which man terms the life of man in unity with nature, and in which man meets with God in nature because he finds his satisfaction there, has ceased to exist. The unity of man with the world is for this end broken, that it may be restored in a higher unity, that the world, as an intelligible world, may be received into God. The relation of man to God thereby reveals itself in the way provided for our salvation in worship, but more particularly it likewise shows itself in Philosophy; and that with the express consciousness of the aim that the individual should render himself capable of belonging to this intelligible world. The manner in which man represents to himself his relation to God is more particularly determined by the manner in which man represents to himself God. What is now often said, that man need not know God, and may yet have the knowledge of this relation, is false. Since God is the First, He determines the relation, and therefore in order to know what is the truth of the relation, man must know God. Since therefore thought goes so far as to deny the natural, what we are now concerned with is not to seek truth in any existing mode, but from our inner Being to go forth again to a true objective, which derives its determination from the intrinsic nature of thought."

— Georg Wilhelm Friedrich Hegel

"The beginning of religion, more precisely its content, is the concept of religion itself, that God is the absolute truth, the truth of all things, and subjectively that religion alone is the absolutely true knowledge."

— Georg Wilhelm Friedrich Hegel

"In affirming that "what is true is the sign of itself and of what is false", Spinoza avoided any problematic which depended on a "criterion of truth ". If you claim to judge the truth of something by some "criterion", you face the problem of the criterion of this criterion -- since it also must be true -- and so on to infinity. Whether the criterion is external or internal , in either case the criterion can be rejected: for it only represents a form of Jurisdiction, a Judge to authenticate and guarantee the validity of what is True. And at the same time Spinoza avoids the temptation of talking about the Truth: as a good nominalist Spinoza only talks about what is "true". In fact the idea of Truth and the idea of the Jurisdiction of a Criterion always go together, because the function of the criterion is to identify the Truth of what is true. Once he has set aside the temptations of a theory of knowledge, Spinoza then says that "what is true" "identifies itself", not as a Presence but as a Product, in the double sense of the term "product" , as it emerges in its own production. Now this position is not unrelated to the "criterion of practice", a major thesis of Marxist philosophy: for this Marxist "criterion" is not exterior but interior to practice, and since this practice is a process the criterion is no form of Jurisdiction; items of knowledge emerge in the process of their production. There again, by the contrast between them, Spinoza allows us to perceive Hegel's mistake."

— Baruch Spinoza

"The significance of that 'absolute commandment', know thyself — whether we look at it in itself or under the historical circumstances of its first utterance — is not to promote mere self-knowledge in respect of the particular capacities, character, propensities, and foibles of the single self. The knowledge it commands means that of man's genuine reality — of what is essentially and ultimately true and real — of spirit as the true and essential being."

— Georg Wilhelm Friedrich Hegel

"If one prefers to have little with blessing, to have truth with concern, to suffer instead of exulting over imagined victories, then one presumably will not be disposed to praise the knowledge, as if what it bestows were at all proportionate to the trouble it causes, although one would not therefore deny that through its pain it educates a person, if he is honest enough to want to be educated rather than to be deceived, out of the multiplicity to seek the one, out of abundance to seek the one thing needful, as this is plainly and simply offered precisely according to the need for it."

— Søren Kierkegaard

"Happily for the country, happily for you and for me, the judgment of James Buchanan, the patrician, was not the judgment of Abraham Lincoln, the plebeian. He brought his strong common sense, sharpened in the school of adversity, to bear upon the question. He did not hesitate, he did not doubt, he did not falter; but at once resolved that at whatever peril, at whatever cost, the union of the States should be preserved. A patriot himself, his faith was strong and unwavering in the patriotism of his countrymen. Timid men said before Mister Lincoln’s inauguration, that we have seen the last president of the United States. A voice in influential quarters said, 'Let the Union slide'. Some said that a Union maintained by the sword was worthless. Others said a rebellion of eight million cannot be suppressed; but in the midst of all this tumult and timidity, and against all this, Abraham Lincoln was clear in his duty, and had an oath in heaven. He calmly and bravely heard the voice of doubt and fear all around him; but he had an oath in heaven, and there was not power enough on earth to make this honest boatman, backwoodsman, and broad-handed splitter of rails evade or violate that sacred oath. He had not been schooled in the ethics of slavery; his plain life had favored his love of truth. He had not been taught that treason and perjury were the proof of honor and honesty. His moral training was against his saying one thing when he meant another. The trust that Abraham Lincoln had in himself and in the people was surprising and grand, but it was also enlightened and well founded. He knew the American people better than they knew themselves, and his truth was based upon this knowledge."

— Frederick Douglass

"Does it follow that I reject all authority? Far from me such a thought. In the matter of boots, I refer to the authority of the bootmaker; concerning houses, canals, or railroads, I consult that of the architect or engineer. For such or such special knowledge I apply to such or such a savant. But I allow neither the bootmaker nor the architect nor the savant to impose his authority upon me. I listen to them freely and with all the respect merited by their intelligence, their character, their knowledge, reserving always my incontestable right of criticism and censure. I do not content myself with consulting authority in any special branch; I consult several; I compare their opinions, and choose that which seems to me the soundest. But I recognize no infallible authority, even in special questions; consequently, whatever respect I may have for the honesty and the sincerity of such or such an individual, I have no absolute faith in any person. Such a faith would be fatal to my reason, to my liberty, and even to the success of my undertakings; it would immediately transform me into a stupid slave, an instrument of the will and interests of others."

— Mikhail Bakunin

"We have reached the point where the Objective Logic turns into the Subjective Logic, or, where subjectivity emerges as the true form of objectivity. We may sum up Hegel’s analysis in the following schema: The true form of reality requires freedom. Freedom requires self-consciousness and knowledge of the truth. Self-consciousness and knowledge of the truth are the essentials of the subject. The form of reality must be conceived as subject. P. 154-155"

— Herbert Marcuse

"I'm interested in truth, I like science. But truth's a menace, science is a public danger. As dangerous as it's been beneficent. … It's curious … to read what people in the time of Our Ford used to write about scientific progress. They seemed to imagine that it could go on indefinitely, regardless of everything else. Knowledge was the highest good, truth the supreme value; all the rest was secondary and subordinate. True, ideas were beginning to change even then. Our Ford himself did a great deal to shift the emphasise from truth and beauty to comfort and happiness. Mass production demanded the shift. Universal happiness keeps the wheels steadily turning; truth and beauty can't. And, of course, whenever the masses seized political power, then it was happiness rather than truth and beauty that mattered. Still, in spite of everything, unrestricted scientific resarch was still permitted. People still went on talking about truth and beauty as though they were sovereign goods. Right up to the time of the Nine Years' War. That made them change their tune all right. What's the point of truth or beauty or knowledge when the anthrax bombs are popping all around you? That was when science first began to be controlled — after the Nine Years' War. People were ready to have even their appetites controlled then. Anything for a quiet life. We've gone on controlling ever since. It hasn't been very good for truth, of course. But it's been very good for happiness. One can't have something for nothing. Happiness has got to be paid for."

— Aldous Huxley

"I affirm, in words as true and literal as any that belong to geometry, that the man who withholds knowledge from a child not only works diabolical miracles for the destruction of good, but for the creation of evil also. He who shuts out truth, by the same act opens the door to all the error that supplies its place. Ignorance breeds monsters to fill up all the vacuities of the soul that are unoccupied by the verities of knowledge. He who dethrones the idea of law, bids chaos welcome in its stead. Superstition is the mathematical complement of religious truth; and just so much less as the life of a human being is reclaimed to good, just so much more is it delivered over to evil. The man or the institution, therefore, that withholds knowledge from a child, or from a race of children, exercises the awful power of changing the world in which they are to live, just as much as though he should annihilate all that is most lovely and grand in this planet of ours, or transport the victim of his cruelty to some dark and frigid zone of the universe, where the sweets of knowledge are unknown, and the terrors of ignorance hold their undisputed and remorseless reign."

— Horace Mann

"“Lines and colors made with earth on earth may hold knowledge in them. All knowledge is local, all truth is partial,” Havzhiva said with an easy, colloquial dignity that he knew was an imitation of his mother, the Heir of the Sun, talking to foreign merchants. “No truth can make another truth untrue. All knowledge is a part of the whole knowledge. A true line, a true color. Once you have seen the larger pattern, you cannot go back to seeing the part as the whole."

— Ursula K. Le Guin

"To say categorically, 'There is no God,' is to make an absolute statement. For the statement to be true, I must know for certain that there is no God in the entire universe. No human being has all knowledge. Therefore, none of us is able to truthfully make this assertion."

— Ray Comfort

"Unfortunately there was one thing that the white South feared more than Negro dishonesty, ignorance, and incompetency, and that was Negro honesty, knowledge, and efficiency."

— W. E. B. Du Bois

"KNOWING YOURSELF means being able to separate the true from the false in yourself - love from emotion, joy from sentiment, Will from desire. No man can teach another self-knowledge. He can only lead him or her up to self-discovery - the source of truth."

"When knowledge is the slave of social considerations, it defines a special class; when it serves its own ends only, it no longer does so. There is of course a profound logic in this paradox: genuine knowledge is egalitarian in that it allows no privileged source, testers, messengers of Truth. It tolerates no privileged and circumscribed data. The autonomy of knowledge is a leveller."

— Ernest Gellner

"Examine the man who lives in misery because he does not shine above other men; who goes about producing himself, pruriently anxious about his gifts and claims; struggling to force everybody, as it were begging everybody for God's sake, to acknowledge him a great man, and set him over the heads of men! Such a creature is among the wretchedest sights seen under this sun. A great man? A poor morbid prurient empty man; fitter for the ward of a hospital, than for a throne among men. I advise you to keep out of his way. He cannot walk on quiet paths; unless you will look at him, wonder at him, write paragraphs about him, he cannot live. It is the emptiness of the man, not his greatness. Because there is nothing in himself, he hungers and thirsts that you would find something in him. In good truth, I believe no great man, not so much as a genuine man who had health and real substance in him of whatever magnitude, was ever much tormented in this way."

— Thomas Carlyle

"An integral approach acknowledges that all views have a degree of truth, but some views are more true than others, more evolved, more developed, more adequate. And so let's get that part out of the way right now: homophobia in any form, as far as I can tell, stems from a lower level of human development — but it is a level, it exists, and one has to make room in one's awareness for those lower levels as well, just as one has to include third grade in any school curriculum. Just don't, you know, put those people in charge of anything important."

"For the truth of the conclusions of physical science, observation is the supreme Court of Appeal. It does not follow that every item which we confidently accept as physical knowledge has actually been certified by the Court; our confidence is that it would be certified by the Court if it were submitted. But it does follow that every item of physical knowledge is of a form which might be submitted to the Court. It must be such that we can specify an observational procedure which would decide whether it is true or not. Clearly a statement cannot be tested by observation unless it is an assertion about the results of observation. Every item of physical knowledge must therefore be an assertion of what has been or would be the result of carrying out a specified observational procedure."

— Arthur Eddington

"If you can’t show that it’s true, then you can’t call it truth. Knowledge is similar to truth in that it a justified belief. Knowledge is demonstrable and testable with measurable accuracy. If you can’t demonstrate your knowledge to any degree at all by any means whatsoever then you don’t actually know what you think you do, no matter how convinced of it you are. Without evidentiary support, then it is only an empty assertion unworthy of serious consideration."

"Whoever wants to know a thing has no way of doing so except by coming into contact with it, that is, by living in its environment. ... If you want knowledge, you must take part in the practice of changing reality. 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."

"The rejection of all myth explanation, the reception of all ascertained truths with regard to the relation of the finite to the infinite is what I term freethought or true religious knowledge. ...he freethinker ...possesses more real religion, more of the relation of the finite to the infinite than any mere believer in myth; his very knowledge makes him in the highest sense of the word a religious man."

— Karl Pearson

"My own experience with regard to the native character has been, of course, very limited. Those Hindus whom I have had the pleasure to know personally in Europe may be looked upon as exceptional, as the best specimens, it may be, that India could produce. Also, my intercourse with them has naturally been such that it could hardly have brought out the darker sides of human nature. During the last twenty years, however, I have had some excellent opportunities of watching a number of native scholars under circumstances where it is not difficult to detect a man's true character — I mean in literary work and, more particularly, in literary controversy. I have watched them carrying on such controversies both among themselves and with certain European scholars, and I feel bound to say that, with hardly one exception, they have displayed a far greater respect for truth and a far more manly and generous spirit than we are accustomed to even in Europe and America. They have shown strength, but no rudeness; nay, I know that nothing has surprised them so much as the coarse invective to which certain Sanskrit scholars have condescended, rudeness of speech being, according to their view of human nature, a safe sign not only of bad breeding, but of want of knowledge. When they were wrong, they have readily admitted their mistakes; when they were right, they have never sneered at their European adversaries. There has been, with few exceptions, no quibbling, no special pleading, no untruthfulness on their part, and certainly none of that low cunning of the scholar who writes down and publishes what he knows perfectly well to be false, and snaps his fingers at those who still value truth and self-respect more highly than victory or applause at any price. Here, too, we might possibly gain by the import cargo."

— Max Müller

"When I attempted, a few minutes ago, to describe our spiritual longings, I was omitting one of their most curious characteristics. We usually notice it just as the moment of vision dies away, as the music ends or as the landscape loses the celestial light. What we feel then has been well described by Keats as “the journey homeward to habitual self.” You know what I mean. For a few minutes we have had the illusion of belonging to that world. Now we wake to find that it is no such thing. We have been mere spectators. Beauty has smiled, but not to welcome us; her face was turned in our direction, but not to see us. We have not been accepted, welcomed, or taken into the dance. We may go when we please, we may stay if we can: “Nobody marks us.” A scientist may reply that since most of the things we call beautiful are inanimate, it is not very surprising that they take no notice of us. That, of course, is true. It is not the physical objects that I am speaking of, but that indescribable something of which they become for a moment the messengers. And part of the bitterness which mixes with the sweetness of that message is due to the fact that it so seldom seems to be a message intended for us but rather something we have overheard. By bitterness I mean pain, not resentment. We should hardly dare to ask that any notice be taken of ourselves. But we pine. The sense that in this universe we are treated as strangers, the longing to be acknowledged, to meet with some response, to bridge some chasm that yawns between us and reality, is part of our inconsolable secret. And surely, from this point of view, the promise of glory, in the sense described, becomes highly relevant to our deep desire. For glory meant good report with God, acceptance by God, response, acknowledgment, and welcome into the heart of things. The door on which we have been knocking all our lives will open at last."

— C. S. Lewis

"The moral relativists ask: what do you mean by should? Here's how you should act: Act in a way so that things are good for you like they would be for someone you're taking care of. But they have to be good for you in a way that's also good for your family, and they have to be good for you and your family also in a way that's good for society , so it's balanced at all those levels. And it has to be good for you, your family, and society right now, AND next week, AND next month, AND a year from now, AND ten years from now. It's this harmonious balancing of multiple layers of Being simultaneously, and that's a Darwinian reality, I would say. Your brain is actually attuned to tell you when you are doing that. And the way it tells you is that it reveals that what you're doing is meaningful. That's the sign. Your nervous system is adapted to do this. It's adapted to exist on the edge between order and chaos. Chaos is where things are so complex that you can't handle it, and order is where things are so rigid that it's too restrictive. In between that, there's a place. It's a place that's meaningful. It's where you're partly stabilized, and partly curious. You're operating in a manner that increases your scope of knowledge, so you're inquiring and growing, and at the same time you're stabilizing and renewing you, your family, society, nature; now, next week, next month, and next year. When you have an intimation of meaning, then you know you're there.""Lies and deception destroy people's lives. When they start telling the truth and acting it out, things get a lot better."

— Jordan Peterson

"Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends — hard work and honesty, courage and fair play, tolerance and curiosity, loyalty and patriotism — these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility — a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task."

— Barack Obama

"I said you know what, I thought my transformation was that I needed to transform into Erika Jayne, but my true transformation took place when Erika Jayne showed me that Erika Girardi was just fine the whole time. It was just a truer, shinier version of myself. And you can be fluent in both of your personas, both your personalities. We all have them, whether you’re on a reality television show or not, whether you’re 47 years old and you’re out there singing and dancing. You’re not the same person at home as you are at work, or with other people, so there are performance personas whether you acknowledge them or not. And transformation is individual. This is my story, my experiences, doing this stuff. Maybe yours is something different, but they’re equally important."

— Erika Jayne

"The truth is that once you discover something is false you lose interest in it. Man no longer treasures what he thought was genuine once he discovers it is false. In this way truth is its own solution. Self-knowledge is the discovery of the false. You do not have to find what is true: when the false is discarded truth is there. It always was. Just keep observing the fact and the change will come automatically and will he lasting."
