Opinion Is Not Knowledge Quotes & Sayings

The true lover of knowledge naturally strives for truth, and is not content with common opinion, but soars with undimmed and unwearied passion till he grasps the essential nature of things. — Plato

There is nothing so difficult as to persuade men that they are ignorant. Bertha, exaggerating the seriousness of the affair, thought it charlatanry to undertake a post without knowledge and without capacity. Fortunately that is not the opinion of the majority, or the government of this enlightened country could not proceed. — W. Somerset Maugham

People can have their opinions about everything in the world, but people's opinions end where the tip of my nose begins. Your opinions of others can only go so far as to where their own shoreline is. The world is for your taking, but other people are not. One is only allowed to have an opinion of me, if that person is done educating him/herself on everything about me. Before people educate themselves on everything about you, they're not allowed to open their venomous mouthes and have an opinion about you. — C. JoyBell C.

The knowledge of Natural-History, being Observation of Matters of Fact, is more certain than most others, and in my slender Opinion, less subject to Mistakes than Reasonings, Hypotheses, and Deductions are; ... These are things we are sure of, so far as our Senses are not fallible; and which, in probability, have been ever since the Creation, and will remain to the End of the World, in the same Condition we now find them. — Hans Sloane

The theory of medicine, therefore, presents what is useful in thought, but does not indicate how it is to be applied in practice-the mode of operation of these principles. The theory, when mastered, gives us a certain kind of knowledge. Thus we say, for example, there are three forms of fevers and nine constitutions. The practice of medicine is not the work which the physician carries out, but is that branch of medical knowledge which, when acquired, enables one to form an opinion upon which to base the proper plan of treatment. — Avicenna

The trouble is that many people regard disagreement as unrelated to either teaching or being taught. They think that everything is just a matter of opinion. I have mine, and you have yours; and our right to our opinions is as inviolable as our right to private property. On such a view, communication cannot be profitable if the profit to be gained is an increase in knowledge. Conversation is hardly better than a ping-pong game of opposed opinions, a game in which no one keeps score, no one wins, and everyone is satisfied because he does not lose - that is, he ends up holding the same opinions he started with. — Mortimer J. Adler

Men ought to know that from nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations. And by this, in an especial manner, we acquire wisdom and knowledge, and see and hear and know what are foul and what are fair, what are bad and what are good, what are sweet and what are unsavory ... . And by the same organ we become mad and delirious, and fears and terrors assail us ... .All these things we endure from the brain when it is not healthy ... .In these ways I am of the opinion that the brain exercises the greatest power in the man. — Hippocrates

If you deliver an opinion at all, it is mere stupidity not to do it with an air of conviction and well-founded knowledge. You make it your own in uttering it, and naturally get fond of it. — George Eliot

Wolf's wool is the best wool, but it cannot be sheared, because the wolf will not comply. With knowledge as with wolves' surliness, the student studies voluntarily, refusing to be less than individual. He "gives his opinion and then rests upon it"; he renders service when there is no reward, and is too reclusive for some things to seem to touch him; not because he has no feeling but because he has so much. — Marianne Moore

Nobody cares about feminist academic writing. That's careerism. These poor women in academia have to talk this silly language that nobody can understand in order to be accepted ... But I recognize the fact that we have this ridiculous system of tenure, that the whole thrust of academia is one that values education, in my opinion, in inverse ratio to its usefulness - and what you write in inverse relationship to its understandability. [ ... ] Academics are forced to write in language no one can understand so that they get tenure. They have to say 'discourse', not 'talk'. Knowledge that is not accessible is not helpful. — Gloria Steinem

Then may we not fairly plead in reply that our true lover of knowledge naturally strives for truth, and is not content with common opinion, but soars with undimmed and unwearied passion till he grasps the essential nature of things with the mental faculty fitted to do so, that is, with the faculty which is akin to reality, and which approaches and unites with it, and begets intelligence and truth as children, and is only released from travail when it has thus reached knowledge and true life and satisfaction? — Plato

It is a paradox that men will gladly devote time every day for many years to learn a science or an art; yet will expect to win a knowledge of the gospel, which comprehends all sciences and arts, through perfunctory glances at books or occasional listening to sermons. The gospel should be studied more intensively than any school or college subject. They who pass opinion on the gospel without having given it intimate and careful study are not lovers of truth, and their opinions are worthless. — G. Homer Durham

It is only because the majority opinion will always be opposed by some that our knowledge and understanding progress. In the process by which opinion is formed, it is very probable that, by the time any view becomes a majority view, it is no longer the best view: somebody will already have advanced beyond the point which the majority have reached. It is because we do not yet know which of the many competing new opinions will prove itself the best that we wait until it has gained sufficient support. — Friedrich August Von Hayek

Locke made the case that religious beliefs are, in the words of the scholar Adam Wolfson, "matters of opinion, opinions to which we are all equally entitled, rather than quanta of truth or knowledge."1 In Locke's formulation, protection against persecution is one of the highest responsibilities of any government or ruler. Locke also argued that where there is coercion and persecution to change hearts and minds, it will "work" only at a very high human cost, producing in its wake both cruelty and hypocrisy. For Locke, no one person should "desire to impose" his or her view of salvation on others. Instead, in his vision of a tolerant society, each individual should be free to follow his or her own path in religion, and respect the right of others to follow their own paths: "Nobody, not even commonwealths," Locke wrote, "have any just title to invade the civil rights and worldly goods of each other upon pretense of religion."2 — Ayaan Hirsi Ali

It indicates a person who has not only good manners but who possesses a sense of balance, a sure mastery of himself, a moral discipline that permits him to subordinate voluntarily his own selfish interest to the wider interests of the society in which he lives. The gentleman, therefore is a cultural person in the noblest sense of the word, if by culture we mean not simply wealth of intellectual knowledge but also the ability to fulfil one's duty and understand one's fellow man by respecting / every principle, every opinion, every faith that is sincerely professed. — Antonio Gramsci

There are many subjects upon which, if we hold an opinion at all, we should hold it tentatively, waiting for more light, and retaining a willingness to be enlightened. Many a bitter and fruitless quarrel might be avoided, if more persons found it possible to maintain this philosophical attitude of mind. Philosophy is, after all, reflection, and the reflective man must realize that he is probably as liable to error as are other men. He is not infallible, nor has the limit of human knowledge been attained in his day and generation. He who realizes this will not assume that his neighbor is always wrong, and he will come to have that wide, conscientious tolerance, which is not indifference, but which is at the farthest remove from the zeal of mere bigotry. — George Stuart Fullerton

There's a voice that says: "So what?"
It's not my voice, it's probably not yours, but it makes itself heard in the arenas of public opinion, querulous and smug and fortified by just a little knowledge, which as always is a dangerous thing. "So what if a bunch of species go extinct?" It says. "Extinction is a natural process. Darwin himself said so, didn't he? Extinction is the complement of evolution, making room for new species to evolve. There have always been extinctions. So why worry about these extinctions currently being caused by humanity?" And there has always been a pilot light burning in your furnace. So why worry when your house is on fire? — David Quammen

Men should friendly confer together, and offer one another their gifts and knowledge in love, and try things one with another, and hold that which is best, and not so stand in their own opinion as if they could not err. — Jakob Bohme

Intelligence is an interesting word. It is also something which, in my opinion, is misunderstood by many people. There are those who believe that we go to school to become intelligent. Or, the more experience a person has on a particular job, the more intelligent they become. This notion is not so. All knowledge is one hundred percent evenly present in all places, at all times. Aware is what you and I want to become. The more aware we become of this truth about intelligence, the better off we will be. — Bob Proctor

Ideological opinion is not merely distinct from knowledge but the enemy of knowledge. — Roger Scruton

Small people delight in what they call consistency-that is, it gives them immense pleasure to say that they believe now exactly as they did ten years ago. This simply amounts to a certificate that they have not grown-that they have not developed-and that they know just as little now as they ever did. The highest possible conception of consistency is to be true to the knowledge of today, without the slightest reference to what your opinion was years ago. — Robert Green Ingersoll

An opinion is not a momentary thing but a process of thinking, shaped by the continuous acquisition of knowledge and the activity of questioning, discussion, and debate. — Neil Postman

Who is so wise as to have a perfect knowledge of all things? Therefore trust not too much to thine own opinion, but be ready also to hear the opinion of others. Thought thine own opinion be good, yet if for the love of God thou foregoest it, and followest that of another, thou shalt the more profit thereby. — Thomas A Kempis

Finally, let me share a feeling of mine, I hope it will not be misinterpreted as pride. I am seventy four now. But still, if they give me a duty in the wooden hut where I used to stay when I was a mentor long years ago, I will gladly run there and try to fulfill that duty. Perhaps, some of our friends can see that task as a simple and trivial one. But I have not underestimated this duty and would never do so. Even today, some people may consider our having lessons with the small circle of young scholars here as a simple and trivial job. However, in my opinion, this is the most important occupation that can take human to the highest levels. — M. Fethullah Gulen

Prejudice is not bigotry or superstition, although prejudice sometimes may degenerate into these. Prejudice is pre-judgment, the answer with which intuition and ancestral consensus of opinion supply a man when he lacks either time or knowledge to arrive at a decision predicated upon pure reason. — Russell Kirk

The shades of difference between other people and me serve to make variety and prevent monotony, but that is all; broadly speaking, we are all alike; and so by studying myself carefully and comparing myself with other people, and noting the divergences, I have been enabled to acquire a knowledge of the human race which I perceive is more accurate and more comprehensive than that which has been acquired and revealed by any other member of our species. As a result, my private and concealed opinion of myself is not of a complimentary sort. It follows that my estimate of the human race is the duplicate of my estimate of myself. — Mark Twain

Our opinion of the gods and our knowledge of men lead us to conclude that it is a general and necessary law of nature to rule whatever one can. This is not a law that we made ourselves, nor were we the first to act upon it when it was made. We found it already in existence, and we shall leave it to exist for ever among those who come after us. We are merely acting in accordance with it, and we know that you or anybody else with the same power as ours would be acting in precisely the same way.
Goodwill shown by the party that is asking for help does not mean security for the prospective ally. What is looked for is a positive preponderance of power in action. — Thucydides

Not all men (and especially the wisest) share the opinion that it is bad for women to be educated. But it is very true that many foolish men have claimed this because it displeased them that women knew more than they did. — Christine De Pizan

What we firmly believe, if it is true, is called knowledge, provided it is either intuitive or inferred (logically or psychologically) from intuitive knowledge from which it follows logically. What we firmly believe, if it is not true, is called error. What we firmly believe, if it is neither knowledge nor error, and also what we believe hesitatingly, because it is, or is derived from, something which has not the highest degree of self-evidence, may be called probable opinion. Thus the greater part of what would commonly pass as knowledge is more or less probable opinion. — Bertrand Russell

Clearly, we have entered a world very different from the world of modernity as previously described. The subject/object distinction has broken down. In this world, foundationalism is a washout;49 the old distinction between fact and opinion is disappearing from view. The quest for certainty, precision, and ahistorical knowledge of objective truth is judged impossible. "Truth" is not an objective entity; the classic dikes between fact and opinion are springing leaks. Of course, not all the tenets of modernity have been sacrificed. Irrationally, philosophical naturalism (for most advocates of this radical hermeneutics), still holds sway; moreover, I must still say something about the place of science in this new model. But some variation of what once held the status of a minority report advanced only by a few intellectuals is now adopted almost everywhere. — D. A. Carson

There is a twofold knowledge of good of which God has made the mind of man capable. The first, that which is merely notional . . . and the other is, that which consists in the sense of the heart, as when the heart is sensible of pleasure and delight in the presence of the idea of it. In the former is exercised merely . . . the understanding, in distinction from the . . . disposition of the soul. Thus there is a difference between having an opinion that God is holy and gracious, and having a sense of the loveliness and beauty of that holiness and grace. There is a difference between having a rational judgment that honey is sweet and having a sense of its sweetness. A man may have the former that knows not how honey tastes; but a man cannot have the latter unless he has an idea of the taste of honey in his mind. — Timothy Keller

Modesty becomes blameworthy if it prevents one from denouncing what clearly should be denounced, such as tyranny or corruption. This form of modesty results in meekness at a time when one needs to be forthright and courageous. Something condemnable (munkar) is condemnable regardless of the status of the person who is engaged in it - whether he or she is a close relative or a person of status, wealth, or authority. There must be agreement, however, among scholars on what is condemnable. One cannot, for example, declare decisively that something is considered condemnable if there is a difference of opinion on it among the scholars. Scholars knowledgeable of the plentitude of juristic differences rarely condemn others. They refrain from such condemnation not because of modesty but because of their extensive knowledge and scholarly insight. Unfortunately, many people today are swift to condemn, which creates another disease: self-righteousness. — Hamza Yusuf

Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. — Bertrand Russell

I am not of the opinion that one can ever lack the power to express perfectly what one wants to write or say. Observations on the weakness of language, and comparisons between the limitations of words and the infinity of feelings, are quite fallacious. The infinite feeling continues to be as infinite in words as it was in the heart. What is clear within is bound to become so in words as well. This is why one need never worry about language, but at sight of words may often worry about oneself. After all, who knows within himself how things really are with him? This tempestuous or floundering or morasslike inner self is what we really are, but by the secret process by which words are forced out of us, our self-knowledge is brought to light, and though it may still be veiled, yet it is there before us, wonderful or terrible to behold. — Franz Kafka

My curiosity, alas, is not the kind that can be satisfied by objective knowledge. Plato said that opinion is worthless and that only knowledge counts, which is a neat formulation. But melancholy [men] from the northern mists understand that opinion is all there is. The great questions transcend fact, and discourse is a process of personality. Knowledge cannot respond to knowledge. And wisdom? Is it not opinion refined, opinion killed and resuscitated upward? Maybe Plato would have agreed with this. — Hayden Carruth

I do not think it is wise to force them to study one thing or another, although persuading them to do so would not be harmful; and when there is no need to study pane lucrando,1 if the student is so fortunate that heaven has endowed him with parents who can spare him that, it would be my opinion that they should allow him to pursue the area of knowledge to which they can see he is inclined; although poetry is less useful than pleasurable, it is not one of those that dishonors the one who knows it. — Miguel De Cervantes Saavedra

If the painter has clumsy hands, he will be apt to introduce them into his works, and so of any other part of his person, which may not happen to be so beautiful as it ought to be. He must, therefore, guard particularly against that self-love, or too good opinion of his own person, and study by every means to acquire the knowledge of what is most beautiful, and of his own defects, that he may adopt the one and avoid the other. — Leonardo Da Vinci

Knowledge is power, as some say. But on some days it is just as much pain and confusion as it is power; and any wise man worth his salt as a wise man at least understands this. One may be able to comprehend all the human perspectives in the universe, but this gives more to decipher regarding what is actually true; and even after discovering the truth, the challenge is in maintaining a patience for the infinite number of opinions that do not reflect that truth. Its consistency in man is challenge. A worldly knowledge ends at the former challenge of confusion, but the knowledge of Christ ends at the latter challenge of patience. — Criss Jami

On religion in particular, the time appears to me to have come, when it is a duty of all who, being qualified in point of knowledge, have, on mature consideration, satisfied themselves that the current opinions are not only false, but hurtful, to make their dissent known. — John Stuart Mill

Professional opinion is skeptical about anything that doesn't fit in with the version of reality it has been programmed to believe in. The skepticism comes from a lack of understanding and the need to defend the status quo and not from actual knowledge of the subject. — David Icke

Always keep in mind that an article of faith is not something that the faithful assume. Faith, for those who have it, is the most certain form of knowledge, not a tentative opinion. — Mortimer J. Adler

You've heard the teachings, oh son of a Brahman, and good for you that you've thought about it thus deeply. You've found a gap in it, an error. You should think about this further. But be warned, oh seeker of knowledge, of the thicket of opinions and of arguing about words. There is nothing to opinions, they may be beautiful or ugly, smart or foolish, everyone can support them or discard them. But the teachings, you've heard from me, are no opinion, and their goal is not to explain the world to those who seek knowledge. They have a different goal; their goal is salvation from suffering. This is what Gotama teaches, nothing else. — Hermann Hesse

I have never worked on interrogation; I have never seen an interrogation, and I have only a passing knowledge of the literature on interrogation. With that qualification, my opinion is that the point of interrogation is to get at the truth, not to get at what the interrogator wants to hear. — Martin Seligman

The philosopher is in love with truth, that is, not with the changing world of sensation, which is the object of opinion, but with the unchanging reality which is the object of knowledge. — Plato

Yet while nature is in constant flux, we always go against the grain and try to freeze our ideas and experiences and make them absolute. It is egotism that makes us identify with one opinion rather than another, become quarrelsome and unkind, say *this* could not mean *that*, and think we have a duty to change others to suit ourselves. — Karen Armstrong

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. — Lord Chesterfield

I suspect that in this comprehensive and (may I say) commonplace censure, you are not judging from yourself, but from prejudiced persons, whose opinions you have been in the habit of hearing. It is impossible that your own observation can have given you much knowledge of the clergy. You can have been personally acquainted with very few of a set of men you condemn so conclusively. — Jane Austen

True it is that every man willingly followeth his own bent, and is the more inclined to those who agree with him. But if Christ is amongst us, then it is necessary that we sometimes yield up our own opinion for the sake of peace. Who is so wise as to have perfect knowledge of all things? Therefore trust not too much to thine own opinion, but be ready also to hear the opinions of others. — Thomas A Kempis

Between knowledge of what really exists and ignorance of what does not exist lies the domain of opinion. It is more obscure than knowledge, but clearer than ignorance. — Plato
