Certain Knowledge Quotes & Sayings

There was never a tutor that did professly teach Felicity, though that be the mistress of all other sciences. Nor did any of us study these things but as aliena, which we ought to have studied as our enjoyments. We studied to inform our knowledge, but knew not for what end we so studied. And for lack of aiming at a certain end we erred in the manner. Howbeit there we received all those seeds of knowledge that were afterwards improved; and our souls were awakened to a discerning of their faculties, and exercise of their powers. — Thomas Traherne

That Muhammad could predict certain events does not prove that he was a prophet: he may have been able to guess successfully, but this does not mean that he had real knowledge of the future. And certainly the fact that he was able to recount events from the past does not prove that he was a prophet, because he could have read about those events in the Bible and, if he was illiterate, he could still have had the Bible read to him. — Muhammad Al Warraq

Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science - by far the most successful claim to knowledge accessible to humans - teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. — Carl Sagan

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

You would be miserable if you had to go through life with a human doormat with 'Welcome' written on him. You want some one made of sterner stuff. You want, as it were, a sparring-partner, some one with whom you can quarrel happily with the certain knowledge that he will not curl up in a ball for you to kick, but will be there with the return wallop. — P.G. Wodehouse

He did not know, and perhaps this doctor did. And he could not take the chance of pitting his certain ignorance against this man's possible knowledge. He was trapped as his people were always trapped, and would be until, as he had said, they could be sure that the things in the books ere really in the books. — John Steinbeck

rationalist believes in reason as the primary source of knowledge, and he may also believe that man has certain innate ideas that exist in the mind prior to all experience. And the clearer such ideas may be, the more certain it is that they correspond to reality. You — Jostein Gaarder

Robert A. Bjork It is natural for people to think that learning is a matter of building up skills or knowledge in one's memory, and that forgetting is a matter of losing some of what was built up. From that perspective, learning is a good thing and forgetting is a bad thing. The relationship between learning and forgetting is not, however, so simple, and in certain important respects is quite the opposite: Conditions that produce forgetting often enable additional learning, for example, and learning or recalling some things is a contributor to the forgetting of other things. — Aaron S. Benjamin

I remember it was with extreme difficulty that I could bring my master to understand the meaning of the word opinion, or how a point could be disputable; because reason taught us to affirm or deny only where we are certain; and beyond our knowledge we cannot do either. — Jonathan Swift

Even the tail of the Sphinx is wrapped around its right hind paw signaling thereby the Earth's direction of rotation as we see with Menkaure's spatial lag (i.e., longitudinal and hence related to the Sunrise) in reference to the other two pyramids. With all other clues popping up in my research, this adds up to the evidence that there were a certain type of knowledge which the later generations of the ancient Egyptians were not aware of even though the structures and monuments of Egypt testified for its presence as we especially observe on the Sphinx. This is an unequivocal manifestation of the loss of that knowledge as a consequence of rebellion and revolution instead of uninterrupted inheritance and authentic tradition. — Ibrahim Ibrahim

Modern physics has changed nothing in the great classical disciplines of, for instance, mechanics, optics, and heat. Only the conception of hitherto unexplored regions, formed prematurely from a knowledge of only certain parts of the world, has undergone a decisive transformation. This conception, however, is always decisive for the future course of research. — Werner Heisenberg

[Photography] allows me to accede to an infra-knowledge; it supplies me with a collection of partial objects and can flatter a certain fetishism of mine: for this 'me' which like knowledge, which nourishes a kind of amorous preference for it. In the same way, I like certain biographical features which, in a writer's life, delight me as much as certain photographs; I have called these features 'biographemes'; Photography has the same relation to History that the biographeme has to biography. — Roland Barthes

The second reason to abandon environmental religion is more pressing. Religions think they know it all, but the unhappy truth of the environment is that we are dealing with incredibly complex, evolving systems, and we usually are not certain how best to proceed. Those who are certain are demonstrating their personality type, or their belief system, not the state of their knowledge. — Michael Crichton

To a certain degree,
We all seek, life's purpose and meaning,
love, peace and joy,
and knowledge, wealth and power ... — I. Alan Appt

One of the things that makes our military the best in the world is the certain knowledge of each soldier, sailor, airman, and Marine that they can always count on their comrades should they need help - that they will never be abandoned. — Jon Kyl

The version of technology we live with most closely resembles the one that Scots such as James Watt organized and perfected. It rests on certain basic principles that the Scottish Enlightenment enshrined: common sense, experience as our best source of knowledge, and arriving at scientific laws by testing general hypotheses through individual experiment and trial and error. — Arthur Herman

I thought they may have presumed too much knowledge of certain things for people who are not comedians. Like Montreal. A comic understands what it is and its importance, but someone else may not know about it. — Todd Barry

Not only is there an art in knowing a thing, but also a certain art in teaching it. — Marcus Tullius Cicero

I used to think I had no will to power. Now I perceive that I vented it on thoughts, rather than people. Conquering an unknown province of knowledge. Getting the better of a problem. Forcing ideas to associate or come apart. Bullying recalcitrant words to assume a certain pattern. All the fun of being a dictator without any risks and responsibilities. — Aldous Huxley

When we approach theology as facts to look at, it is easy to allow certain theological debates to replace Scripture as our primary theological subject matter. These debates - such as the categorization of God's attributes, the nature of predestination, the age of the earth, and the continuation of certain spiritual gifts - are not unimportant issues, and sometimes the church must return to them for extended theological reflection. However, the church's mission is derailed when theology becomes little more than a discipline helping people know what to believe about these particular issues. These debates are necessary to the task of theology, but they are not primary. The primary role of theology is to cultivate in us a love for and knowledge of — Daniel L. Akin

The worthiest man to be known, and for a pattern to be presented to the world, he is the man of whom we have most certain knowledge. He hath been declared and enlightened by the most clear-seeing men that ever were; the testimonies we have of him are in faithfulness and sufficiency most admirable. — Michel De Montaigne

The damned had been given that insight which makes hardship so easy to bear - the absolute and certain knowledge that things could be worse. — Terry Pratchett

Unfortunately, the optimistic view that "classical civilization" handed down certain fundamental works that managed to include the knowledge contained in the lost writings has proved groundless. In fact, in the face of a general regression in the level of civilization, it's never the best works that will be saved through an automatic process of natural selection. — Lucio Russo

Faith is indeed intellectual; it involves an apprehension of certain things as facts; and vain is the modern effort to divorce faith from knowledge. But although faith is intellectual, it is not only intellectual. You cannot have faith without having knowledge; but you will not have faith if you have only knowledge. — J. Gresham Machen

Knowledge is never in doubt. Wisdom is never certain. — Dee Hock

Now, it's common knowledge that most towns of a certain size have a witch, if only to eat misbehaving children and the occasional puppy who wanders into her yard. — John August

As a little kid, Peter had figured that once you reached a certain age, somebody just handed you all the knowledge you'd need in order to be an adult. But it turned out that wasn't how it worked. — Tommy Wallach

The epoch of doubt and transition during which the Greeks passed from the dim fancies of mythology to the fierce light of science was the age of Pericles, and the endeavour to substitute certain truth for the prescriptions of impaired authorities, which was then beginning to absorb the energies of the Greek intellect, is the grandest movement in the profane annals of mankind, for to it we owe, even after the immeasurable progress accomplished by Christianity, much of our philosophy and far the better part of the political knowledge we possess. — Lord Acton

The more certain our knowledge the less we know. — Georg Wilhelm Friedrich Hegel

I had grown accustomed to living within myself. I was resigned to the knowledge that I had lost all appreciation of the outside world, that the loss of its bright colors was an inseparable part of the loss of my childhood, and that, in a certain sense, one had to pay for freedom and maturity of the soul with the renunciation of this cherished aura. But now, overjoyed, I saw that all this had only been buried or clouded over and that it was still possible - even if you had become liberated and had renounced your childhood happiness - to see the world shine and to savor the delicious thrill of the child's vision. — Hermann Hesse

Let us being again. To take some examples: why should "literature" still designate that which already breaks away from literature - away from what has always been conceived and signified under that name - or that which, not merely escaping literature, implacably destroys it? (Posed in these terms, the question would already be caught in the assurance of a certain fore-knowledge: can "what has always been conceived and signified under that name" be considered fundamentally homogeneous, univocal, or nonconflictual?) To take other examples: what historical and strategic function should henceforth be assigned to the quotation marks, whether visible or invisible, which transform this into a "book," or which still make the deconstruction of philosophy into a "philosophical discourse"? — Jacques Derrida

No progressive knowledge will ever medicine that dread misgiving of a mysterious and pathless power given to words of a certain import. — Thomas De Quincey

Americans live with the certain knowledge that the source of their greatness has not yet been released. — Ralph Steadman

There is no such thing as absolute cost of labour; it is all a matter of comparison. Every one gets the most which he can for his exertions; some can get little or nothing, because they have not sufficient strength, knowledge or ingenuity; others get much, because they have, comparatively speaking, a monopoly of certain powers. — William Stanley Jevons

One thing in any case is certain: man is neither the oldest nor the most constant problem that has been posed for human knowledge. — Michel Foucault

Nor is it in fact a purely human knowledge bound by the context and categories of the human mind. Rather, metaphysics, which some of his translators render as metaphysic in order to emphasize its non-multiple but unitary nature, is the science of Ultimate Reality, attainable through the intellect and not reason, of an essentially suprahuman character and including in its fullness the whole of man's being. It is a sacred science or scientia sacra, a wisdom which liberates and which requires not only certain mental capacities but also moral and spiritual qualifications. It — Frithjof Schuon

In the years after the death of Petrus, Hillegond had refused all offers of marriage, certain that her knowledge of men, despite her uncountable intimate encounters with them, was seriously bescrewed. Further, she grew certain from a recurring nightmare that should she ever consider a man as a second spouse, he would strangle her in her bed with a ligature. — William Kennedy

I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don't have time for such study. — Donald Knuth

If you are armed with knowledge, if you are aware that certain dynamics are at play then you have options. You can play defense, you can ignore certain person and take the consequences perhaps with a game plan in mind and it goes on, you've increased your options. — Robert Greene

The engineered built environments or domesticated landscapes of certain Amazonian peoples were as impressive as any Egyptian pyramid, Mesopotamian city, or Chinese terrace-irrigiation system. In the Amazon, the transformation was driven by social demands: social group formation, domestic routines, territoriality, local environmental knowledge, gifting, and competitive feasting. — Clark L. Erickson

Young Reggie Foljambe to my certain knowledge offered him double what I was giving him, and Alistair Bingham-Reeves, who's got a valet who had been known to press his trousers sideways, used to look at him, when he came to see me, with a kind of glittering, hungry eye which disturbed me deucedly. Bally pirates! — P.G. Wodehouse

In some subsequent episodes, certain individuals have certain knowledge of certain events that they wouldn't have, if they didn't have access to the future. — Andrew Kreisberg

Archimedes was a mathematician," blurted Ethan from the back of the room. "And he was Greek. And he invented things." Ethan was the sort of student who was always keeping score
if he couldn't be the first to declare his knowledge of something, he would make certain you understood that he'd known it already. One day he would be declared the winner, and there would be a Smartest Boy trophy and a parade. — Adam Rex

The town draws a veil over certain events. This is a small community where everyone knows that sometimes the contract to forget is as important as any promise to remember. Children can grow up having no knowledge of the indiscretion of their father in his youth or the illegitimate sibling who lives fifty miles away and bears another man's name. History is that which is agreed upon by mutual consent. That's how life goes on; protected by the silence that anaesthetises shame. — M.L. Stedman

For me, the present agony of departure, the silent terror of leaving a place known to me if hated, the well-nigh impossible task of conquering the fear that possessed me. Not the fear of that hasty look round, the sudden plunge headlong and the giddy shock of hard, cold water, the river itself entering my lungs, rising in my throat, tossing me upon my back with my arms outflung - I could hear the sob strangled in my chest and the blood leave me - but fear of the certain knowledge that there was no returning, no possible means of escape, and no other thing beyond. — Daphne Du Maurier

He feared at certain moments that the only new knowledge he would take away from this country was learning how to swim and use the telephone. — Damon Galgut

The beatings at Repton were more fierce and more frequent than anything I had yet experienced. And do not think for one moment that the future Archbishop of Canterbury objected to these squalid exercises. He rolled up his sleeves and joined in with gusto. His were the bad ones, the really terrifying occasions. Some of the beatings administered by this man of God, this future Head of the Church of England, were very brutal. To my certain knowledge he once had to produce a basin of water, a sponge and a towel so that the victim could wash the blood away afterwards. No joke, that. Shades of the Spanish Inquisition. — Roald Dahl

Truth ain't be in secret site to be found.
It lies within certain levels of understanding and knowledge. — Toba Beta

The problem is, at a certain point you can't stop thinking even if you want to. I swear, sometimes you just wish you could go back into the dark like a primitive person. But you cant, that's the problem with evolution. Once you have a little bit of knowledge, more of it just keeps coming at you like birds around a bagel. Sometimes when I learn things, I wish I hadn't learned them. — Victor Lodato

I don't think you have to wait for knowledge and balance to come before you seek power because you need a certain amount of power to gain knowledge and balance. — Frederick Lenz

Aging offers certain rewards that youth cannot. It represents the culmination of our efforts in building self-knowledge, families, friendships, careers, and the sense of self that comes from facing whatever adversity we may have encountered. Aging is to be honored. Youth certainly has its own set of rewards, but to dwell on them to the exclusion of those that come later in life causes a stagnation of the self. It keeps us from experiencing an appreciation of living an entire (ital) life, not just the beginning. When we're really old we will likely measure our lives by how well we loved, how well we were loved, and by what we created, whether that be family, work, art, or friendships. Even if we have chosen to have them, we will probably not measure our lives collagen injection by collagen injection. — Joyce T. McFadden

Power doesn't make you happy. Actually, power without knowledge and balance is problematic. Power is something that will automatically follow when you have knowledge. The two are really the same, in a certain sense. — Frederick Lenz

First, you must be certain that you are ready for knowledge. There are many things that we bury in our minds for a reason. Are you sure that you want to go digging up the past?"- Elsie (Marked Book #1) page 226 — A.N. Meade

There are proven ways to win the loyalty of tough, strong, ferocious men: play on the certain knowledge of their superiority, the mystique of secret covenant, the esprit of shared suffering. — Frank Herbert

village." The scholar, Lewis declares, has "lived in many times" and can thus challenge the automatic presumption of finality inherent in present judgements and trends: We need intimate knowledge of the past. Not that the past has any magic about it, but because we cannot study the future, and yet need something to set against the present, to remind us that the basic assumptions have been quite different in different periods and that much which seems certain to the uneducated is merely temporary fashion.58 — Alister E. McGrath

Human knowledge progresses when people recognize that they may be wrong even on issues that seem certain to them. Wisdom involves openness to those who disagree with us. It is only when our ideas have been subjected to criticism and all objections considered - if necessary seeking these objections out - that we have any right to think of our judgement as better than another's. — Nigel Warburton

The divine Ground of all existence is a spiritual Absolute, ineffable in terms of discursive thought, but (in certain circumstances) susceptible of being directly experienced and realized by the human being. This Absolute is the God-without-form of Hindu and Christian mystical phraseology. The last end of man, the ultimate reason for human existence, is unitive knowledge of the divine Ground - the knowledge that can come only to those who are prepared to "Die to self" and so make room, as it were, for God. — Aldous Huxley

There are certain truths which stand out so openly on the roadsides of life, as it were, that every passer-by may see them. Yet, because of their obviousness, the general run of people disregard such truths or at least they do not make them the object of any concious knowledge. People are so bliend to some of the simplest facts in everyday life that they are highly surprised when somebody calls attention to what everybody ought to know. — Adolf Hitler

I practiced law for five years and that gives you insight into a certain mind-set that maybe a lot of writers haven't had firsthand access to. There's an almost casual cruelty, a very low level of overall awareness, but sometimes there's also knowledge that real damage is being done - this attitude of "Oh, what the hell," this kind of moral cognitive dissonance. These are people who have never missed a meal. It's an unknowingness, an unawareness ... Many people were operating from a very narrow range of experience, and yet they had complete faith in it. Their way was the correct way, the only way. They had virtually no awareness of any other way of life except in terms of demonizing things ... It's an extremely blindered experience of the world. — Ben Fountain

The slenderest knowledge that may be obtained of the highest things is more desirable than the most certain knowledge obtained of lesser things. — Thomas Aquinas

As we gain knowledge, we do not become more certain, we become certain of more. — Ayn Rand

Our first wisdom as a species, that unique metaphorical knowledge that distinguishes us, grew out of such an intimacy with the earth; and, however far we may have come since that time, it did not seem impossible to me that night to go back and find it. I wanted to enquire among these people, for what we now decide to do in the North has a certain frightening irrevocability about it. — Barry Lopez

Can the same nature be a lover of wisdom and a lover of falsehood? Never. The true lover of learning then must from his earliest youth, as far as in him lies, desire all truth? Assuredly. But then again, as we know by experience, he whose desires are strong in one direction will have them weaker in others; they will be like a stream which has been drawn off into another channel. True. He whose desires are drawn towards knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasure - I mean, if he be a true philosopher and not a sham one. That is most certain. Such — Plato

Critics for established venues are vetted by editors; they usually demonstrate a certain objectivity; and they come with known backgrounds and specialized knowledge. — Michael Dirda

The Unknown is not the Unknowable; it need not remain the unknown for us, unless we choose ignorance or persist in our first limitations. For to all things that are not unknowable, all things in the universe, there correspond in that universe faculties which can take cognisance of them, and in man, the microcosm, these faculties are always existant and at a certain stage capable of development. We may choose not to develop them; where they are partially developed, we may discourage and impose on them a kind of atrophy. But, fundamentally all possible knowledge is knowledge within the power of humanity. And since in man there is the inalienable impulse of Nature towards self-realisation, no struggle of the intellect to limit the action of our capacities within a determined area can for ever prevail. — Sri Aurobindo

In M
, an important town in northern Italy, the widowed Marquise of O
, a lady of unblemished reputation and the mother of several well-brought-up children, inserted the following announcement in the newspapers: that she had, without knowledge of the cause, come to find herself in a certain situation; that she would like the father of the child she was expecting to disclose his identity to her; that she was resolved, out of consideration to her family, to marry him. — Heinrich Von Kleist

Scientific knowledge is a body of statements of varying degrees of certainty
some most unsure, some nearly sure, none absolutely certain. — Richard P. Feynman

Paul observed, We brought nothing into this world, and it is certain we can carry nothing out (1 Timothy 6:7). He was referring to material things, wealth. However, we will take our knowledge and experience and training from this life with us into the next life. — David Berg

To young people born under the weird planet of the SAT, intelligence was equated with agility, with raw acuity. It produced a certain sort of person of which I was a typical specimen: the mental contortionist, able to rise to almost every challenge placed before him, except the challenge of real self-knowledge. — Walter Kirn

For successful education there must always be a certain freshness in the knowledge dealt with. It must be either new in itself or invested with some novelty of application to the new world of new times. Knowledge does not keep any better than fish. You may be dealing with knowledge of the old species, with some old truth; but somehow it must come to the students, as it were, just drawn out of the sea and with the freshness of its immediate importance. — Alfred North Whitehead

His ministrations were tender, his eyes hooded as he seemed to withhold certain emotions from her. She allowed him his secrets, and took what he gave with a greed that shocked her with its intensity. But he never had to know. He never had to glimpse how deeply she felt for him, or discover the secret she had always suspected and finally admitted to herself.
She loved him.
Completely. Every part of him, good and bad, her friend and lover and partner and rival. She wanted to spend the rest of her life with him, giving him everything, even though she knew he didn't want her. She crammed the knowledge to a secret place in- side. Then realized she'd take whatever he gave, even though it would never be enough. — Jennifer Probst

We love certain things because they are longing for us. — Debasish Mridha

In mysticism, knowledge cannot be separated from a certain way of life which becomes its living manifestation. To acquire mystical knowledge means to undergo a transformation; one could even say that the knowledge is the transformation. Scientific knowledge, on the other hand, can often stay abstract and theoretical. Thus most of today's physicists do not seem to realize the philosophical, cultural and spiritual implications of their theories. — Lois McMaster Bujold

I think that we shall have to get accustomed to the idea that we must not look upon science as a 'body of knowledge,' but rather as a system of hypotheses; that is to say, as a system of guesses or anticipations which in principle cannot be justified, but with which we work as long as they stand up to tests, and of which we are never justified in saying that we know they are 'true' or 'more or less certain' or even 'probable.' — Karl Popper

Its true that we learn a lot from science about how we function but there's a danger in thinking knowledge of how we function is the full account of what we are. If you're a chemist who is really interested in the optical properties of certain pigments you could analyse the Mona Lisa and describe it completely but you would never have mentioned the face, which is the meaning of this thing. In that way a neuroscientist can put together an enormously impressively picture of the brain but he would not have described what goes on when we react to another person. — Roger Scruton

America's libraries are the fruits of a great democracy. They exist because we believe that memory and truth are important. They exists because we believe that information an knowledge are not the exclusive domain of a certain type or class of person but rather the province of all who seek to learn. A democratic society holds these institutions in high regard. — Robert S Martin

There are certain things that have universal attributes, like music. Something of greater magnitude is conveyed by them. They connect us with the universal storehouse of life and knowledge. — Swami Paramananda

An increased power of reflection like an increased knowledge only adds to man's affliction, and above all it is certain that for the individual as for the generation no task is more difficult than to escape from the temptations of reflection, simply because they are so dialectical and the result of one clever discovery may give the whole question a new turn, because at any moment reflection is capable of explaining everything quite differently and allowing one some way of escape; because at the last moment of a reflective decision reflection is capable of changing everything
after one has made far greater exertions than are necessary to get a man of character into the midst of things. — Soren Kierkegaard

And here are trees and I know their gnarled surface, water and I feel its taste. These scents of grass and stars at night, certain evenings when the heart relaxes-how shall I negate this world whose power and strength I feel? Yet all the knowledge on earth will give me nothing to assure me that this world is mine. You describe it to me and you teach me to classify it. You enumerate its laws and in my thirst for knowledge I admit that they are true. You take apart its mechanism and my hope increases. At the final stage you teach me that this wondrous and multicolored universe can be reduced to the atom and that the atom itself can be reduced to the electron. All this is good and I wait for you to continue. But you tell me of an invisible planetary system in which electrons gravitate around a nucleus. You explain this world to me with an image. I realize then that you have been reduced to poetry: I shall never know. — Albert Camus

Bealer argues that the kind of naturalistic view which Quine holds will rob him of the ability to make the normative claims which (many) naturalists wish to make in epistemology. I don't think this is right about Quine, but I'm certain it's not right about my own view. To the extent that I can show that talk of knowledge is firmly rooted within empirical theories where it plays an important explanatory role, I thereby demonstrate its naturalistic credentials. — Hilary Kornblith

It takes a certain skill set to be partnered. You have the biological knowledge of the machine. What are the parts, where are they located, how do they work, what do they do? Then there is your intellectual understanding about sex, in history, what you believe about sex, what you were taught about sex. Then there's you intrapersonal skill, your relationship with yourself. Then there are interpersonal skills. — Nina Hartley

I seriously feel like the best days are ahead, and I like the idea of getting to do everything I did before but with more knowledge, experience, and street smarts. There's a certain love, appreciation, and gratitude that you have at 40 that you don't have when you're younger, and it makes every accomplishment feel so much better. — Jennifer Lopez

It is by no means certain that we advance our philosophical quest by reading Plato or Aristotle. It may increase our knowledge of history but not of the world. — Jostein Gaarder

There's a difference between suspecting a thing and finally knowing it for certain. — Glenn Beck

In real science a hypothesis can never be proved true ... A science which confines itself to correlating phenomena can never learn anything about the reality underlying the phenomena, while a science which goes further than this and introduces hypotheses about reality, can never acquire certain knowledge of a positive kind about reality; in whatever way we proceed, this is forever denied us. — James Jeans

Beyond the element of giving, the active characteristic of love becomes evident in the fact that it always implies certain basic elements, common to all forms of love. These are care, responsability, respect and knowledge — Erich Fromm

Logic is our assurance," MacDonald said calmly. "The only thing worth sending from star to star is information, and the certain profit from such an exchange far outweighs the uncertain advantage from any other kind of behavior. The first benefit is the knowledge of other intelligent creatures in the universe - this alone gives us strength and courage. Then comes information from an alien world; it is like having our own instruments there, even our own scientists, to measure and record, only with the additional advantage of a breadth and duration of measurements under a variety of conditions. Finally comes the cultural and scientific knowledge and development of another race, and the treasure to be gained from this kind of exchange is beyond calculation. — James Edwin Gunn

There is cold comfort to be drawn from the sure and certain knowledge that the correct way to deal with the problem you're facing in your job involves napalm, if — Charles Stross

At this point, godless materialists might be cheering. If humans evolved strictly by mutation and natural selection, who needs God to explain us? To this, I reply: I do. The comparison of chimp and human sequences, interesting as it is, does not tell us what it means to be human. In my views, DNA sequence alone, even if accompanied by a vast trove of data on biological function, will never explain certain special human attributes, such as the knowledge of the Moral Law and the universal search for God. Freeing God from the burden of special acts of creation does not remove Him as the source of the things that make humanity special, and of the universe itself. It merely shows us something of how He operates. — Francis S. Collins

Yet there is
no return: rolling up out of chaos,
a nine months' wonder, the city
the man, an identity - it can't be
otherwise - an
interpenetration, both ways. Rolling
up! Obverse, reverse;
the drunk the sober; the illustrious
the gross; one. In ignorance
a certain knowledge and knowledge,
undispersed, its own undoing. — William Carlos Williams

What each man does is based not on direct and certain knowledge, but on pictures made by himself or given to him ... The way in which the world is imagined determines at any particular moment what men will do. — Walter Lippmann

It is clear, then, that wisdom is knowledge having to do with certain principles and causes. But now, since it is this knowledge that we are seeking, we must consider the following point: of what kind of principles and of what kind of causes is wisdom the knowledge? — Aristotle.

They knew many things but had no idea why. And strangely this made them more, rather than less, certain that they were right. — Neal Stephenson

Relations of power "are indissociable from a discourse of truth, and they can neither be established nor function unless a true discourse is produced, accumulated, put into circulation, and set to work. Power cannot be exercised unless a certain economy of discourses of truth functions in, on the basis of, and thanks to, that power." — Michel Foucault

Yes, there have been ET visitations. There have been crashed craft. There have been material and bodies recovered. There has been a certain amount of reverse engineering that has allowed some of these craft, or some components, to be duplicated. And there is some group of people that may or may not be associated with government at this point that have this knowledge. They have been attempting to conceal this knowledge. People in high level government have very little, if any, valid information about this. It has been the subject of disinformation in order to deflect attention and create confusion so the truth doesn't come out. — Edgar D. Mitchell

The thing I understood least of all was that knowledge led to despair and damnation. Our spiritual mentor had not said that those bad books had given a false picture of life: if that had been the case, he could easily have exposed their falsehood; the tragedy of the little girl whom he had failed to bring to salvation was that she had made a premature discovery of the true nature of reality. Well, anyhow, I thought, I shall discover it myself one day, and it isn't going to kill me: the idea that there was a certain age when knowledge of the truth could prove fatal I found offensive to common sense. — Simone De Beauvoir

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

IGNORAMUS, n. A person unacquainted with certain kinds of knowledge familiar to yourself, and having certain other kinds that you know nothing about. — Ambrose Bierce

To minds tormented by the divine thirst, it is useless to offer the most certain knowledge of the laws of numbers and the arrangement of the universe — Etienne Gilson

The truly educated man is not a man who knows a bit of everything, not even a man who knows all the details of all subjects (if such a thing were possible). The whole man in fact may have little detailed knowledge of facts and theories ... but he will be truly in touch with the centre. He will not be in doubt about his basic convictions, about his own view on the meaning and purpose of life. He may not be able to explain these matters in words, but the conduct of his life will show a certain sureness of touch which stems from his inner clarity. — E.F. Schumacher
