Limits Of Knowledge Quotes & Sayings

Reason should take on anew the most difficult of all its tasks, namely, that of self-knowledge, and to institute a court of justice, by which reason may secure its rightful claims while dismissing all its groundless pretensions, and this not by mere decrees but according to its own eternal and unchangeable laws; and this court is none other than the critique of pure reason itself. — Immanuel Kant

A man's pursuit of knowledge is greater than his shortcomings, the limits of his vision. — Natasha Trethewey

For every decision a 'man' makes, he makes it with the best of the depth of knowledge he possess at that particular instant and the quality of experiences he's passed through. It's not an excuse though for mediocrity, but an avenue to learn, rise, and conquer your inefficient self. By inference, beyond an extreme line, there might not necessarily be a qualification of a choice as wrong or right, but an avenue to grow depending on how the intricacies of such a choice and its consequences are handled. — Ufuoma Apoki

This is known, and what is not known does not undermine it. This is the scientific way. To be open about the limits of one's knowledge increases public confidence in what one says is known. — Salman Rushdie

The fact that no limits exist to the destructiveness of this weapon [the 'Super', i.e. the hydrogen bomb] makes its very existence and the knowledge of its construction a danger to humanity as a whole. It is necessarily an evil thing considered in any light. For these reasons, we believe it important for the President of the United States to tell the American public and the world what we think is wrong on fundamental ethical principles to initiate the development of such a weapon. — Enrico Fermi

The pretensions of final truth are always partlyan effort to obscure a darkly felt consciousness of the limits of human knowledge. — Reinhold Niebuhr

The conventional explanation, that God sends us the burden He knows that we are strong enough to handle it, has it all wrong. Fate, not God, sends us the problem. When we try to deal with it, we find out that we are not strong. We are weak, we get tired, we get angry, overwhelmed. We begin to wonder how we will ever make it through all the years. But when we reach the limits of our own strength, and courage, something unexpected happens. We find reinforcement coming from a source outside of ourselves. And in the knowledge that we are not alone, that God is on our side, we manage to go on. — Harold S. Kushner

If we would serve science, we must extend her limits, not only as far as our own knowledge is concerned, but in the estimation of others. — Rudolf Virchow

the past, like the future, is dark. There is so much we don't know, and to write truthfully about a life, your own or your mother's, or a celebrated figure's, an event, a crisis, another culture is to engage repeatedly with those patches of darkness, those nights of history, those places of unknowing. They tell us that there are limits to knowledge, that there are essential mysteries, starting with the notion that we know just what someone thought or felt in the absence of exact information. Often — Rebecca Solnit

Skepticism is thus a resting-place for human reason, where it can reflect upon its dogmatic wanderings and make survey of the region in which it finds itself, so that for the future it may be able to choose its path with more certainty. But it is no dwelling-place for permanent settlement. Such can be obtained only through perfect certainty in our knowledge, alike of the objects themselves and of the limits within which all our knowledge of objects is enclosed. — Immanuel Kant

I came to accept during my freshman year that many of the gaps in my knowledge and understanding were simply limits of class and cultural background, not lack of aptitude or application as I'd feared. — Sonia Sotomayor

Knowledge for the sake of understanding, not merely to prevail, that isthe essence of ourbeing.None candefine its limits, or set its ultimate boundaries. — Vannevar Bush

At present, however, science, spurred on by its powerful delusion, is hurrying unstoppably to its limits, where the optimism hidden in the essence oflogic will founder and break up. For there is an infinite number ofpoints on the periphery ofthe circle ofscience, and while we have no way of foreseeing how the circle could ever be completed, a noble and gifted man inevitably encounters, before the mid-point of his existence, boundary points on the periphery like this, where he stares into that which cannot be illuminated. When, to his horror, he sees how logic curls up around itself at these limits and finally bites its own tail, then a new form ofknowledge breaks through, tragic knowledge, which, simply to be endured, needs art for protection and as medicine."
Friedrich Nietzsche, "Foreword to Richard Wagner" in The Birth of Tragedy, ed. R. Geuss & R. Speirs, Cambridge, 2007, 163. (p.114) — Friedrich Nietzsche

Your minds have limits but not your hearts, for they are receptacles of endless capacity; but you must open your hearts to this knowledge, as nothing may pass through what is closed. Allah loves the brokenhearted. You are coveting a little water in a clay jug, but when you break it that water rejoins the lake from whence it came. Our egos try to prevent that reunion, and always object to any suggestion of the need to seek reunion. The main purpose of spiritual exercises in any tradition, East or West, is to enable us to overcome the objections put forward by our egos, so that we may pursue our journey to Unity Oceans. — Muhammad Nazim Adil Al-Haqqani

The people I go after are the false experts, those who do not accept the limits of their knowledge. — Nassim Nicholas Taleb

Either god exists or it doesn't exist. If a god does exist, it either interacts with the universe in some detectable way or it doesn't. If it doesn't, that god is indistinguishable from a non-existent god. That only leaves a god who interacts with the universe in some detectable way. But if science, which is the greatest realization of the use of our senses to, you know, detect things, hasn't found this god, that doesn't say much for individuals.
In short, the god you've created is, in fact, undetectable by science. The limits of science are not the province of religious knowledge. Where science is ignorant, so is religion. The only difference is that religion lacks the integrity of science. — Matt Dillahunty

It is human nature to believe that the phenomena we know are the only ones that exist," Marie wrote, "and whenever some chance discovery extends the limits of our knowledge we are filled with amazement." She was talking about radioactivity, but she could almost have been talking about the supernatural: "We cannot become accustomed to the idea that we live in a world that is revealed to us only in a restricted portion of its manifestations. — Kathleen Krull

At the opposite pole to this nature of shadows, madness fascinates because it is knowledge. It is knowledge, first, because all these absurd figures are in reality elements of a difficult, hermetic, esoteric learning. These strange forms are situated, from the first, in the space of the Great Secret, and the Saint Anthony who is tempted by them is not a victim of the violence of desire but of the much more insidious lure of curiosity; he is tempted by that distant and intimate knowledge which is offered, and at the same time evaded, by the smile of the gryllos; his backward movement is nothing but that step by which he keeps from crossing the forbidden limits of knowledge; he knows already - and — Michel Foucault

For the stone from the top for geologists, the knowledge of the limits of endurance for the doctors, but above all for the spirit of adventure to keep alive the soul of man. — George Mallory

Like all schools, we are always interested in learning, in research, in pushing the limits of knowledge. But we must balance that with our duty to protect the world, even from ourselves. — Holly Black

Knowledge about yourself binds, weighs, ties you down; there is no freedom to move, and you act and move within the limits of thatknowledge. Learning about yourself is never the same as accumulating knowledge about yourself. Learning is active present and knowledge is the past; if you are learning to accumulate, it ceases to be learning; knowledge is static, more can be added to it or taken away from it, but learning is active, nothing can be added or taken away from it for there is no accumulation at any time. — Jiddu Krishnamurti

There may be things that are completely unknowable to us, so we must be careful not to treat the limits of our knowledge as sure guides to the limit of what there is. — Daniel Dennett

The good pupils are often brilliant, and they keep you on your toes and take you to the limits of your knowledge. The worst pupils provide a unique insight into the criminal mind. — John Le Carre

Whereas young people become accomplished in geometry and mathematics, and wise within these limits, prudent young people do not seem to be found. The reason is that prudence is concerned with particulars as well as universals, and particulars become known from experience, but a young person lacks experience, since some length of time is needed to produce it. — Aristotle.

Realization is not knowledge about the universe, but the living experience of the nature of the universe. Until we have such living experience, we remain dependent on examples, and subject to their limits. — Namkhai Norbu

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary - the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation. — Edwin Powell Hubble

A blind man's world is bounded by the limits of his touch; an ignorant man's world by the limits of his knowledge: a great man's world by the limits of his vision. — E. Paul Hovey

I felt compassion for the poor people who were taken in by [supernatural] follies. And now I think that I was at least as much to be pitied myself. Not that experience has since shown me anything surpassing my first beliefs, and that through no fault of my curiosity; but reason has taught me to condemn a thing thus, dogmatically, as false and impossible, is to assume the distinction of knowing the bounds and limits of God's will and of the power of our mother Nature; and that there is no more notable folly in the world than to measure these things by our capacity and competence. If we call prodigies or miracles whatever our reason cannot reach, how many of these appear continually before our eyes! Let us consider through what clouds and how gropingly we are led to the knowledge of most of the things that are right in our hands; assuredly we shall find that it is rather familiarity than knowledge that takes away their strangeness. — Michel De Montaigne

Our categories arise from the fact that we are neural beings, from the nature of our bodily capacities, from our experience interacting in the world, and from our evolved capacity for basic-level categorization - a level at which we optimally interact with the world. Evolution has not required us to be as accurate above and below the basic level as at the basic level, and so we are not. — George Lakoff

He is a pandit (man of knowledge) who speaks what is suitable to the occasion, who renders loving service according to his ability, and who knows the limits of his anger. — Chanakya

There seems no limit to research, for as been truly said, the more the sphere of knowledge grows, the larger becomes the surface of contact with the unknown. — William Cecil Dampier

I remember Bob saying, 'Some people who believe in God are good, and some people who believe in God are not good. So where does that leave you?' He had looked around and decided that religion is responsible for a lot of trouble in the world.' Noyce, always pushing against the limits of accepted knowledge, told Bowers that what bothered him most about organized religions was that 'people don't think in churches. — Leslie Berlin

When it comes to identity we are all constructs. Who we think we are is the result of our upbringing, memories, skill set, knowledge, experiences and personal belief system. Of all the onion layers that make us who we are, our belief system is what powers our core. It's what creates the essence of a human being and makes it possible for each of us to exceed our limits, confound expectations and do the impossible. — David Amerland

Only the heart knows the correct answer. Most people think the heart is mushy and sentimental. But it's not. The heart is intuitive; it's holistic, it's contextual, it's relational. It doesn't have a win-lose orientation. It taps into the cosmic computer - the field of pure potentiality, pure knowledge, and infinite organizing power - and takes everything into account. At times it may not even seem rational, but the heart has a computing ability that is far more accurate and far more precise than anything within the limits of rational thought. — Deepak Chopra

Education: that which reveals to the wise, and conceals from the stupid, the vast limits of their knowledge. — Mark Twain

Spurious prudence, making the senses final, is the god of sots and cowards, and is the subject of all comedy. It is nature's joke, and therefore literature's. True prudence limits this sensualism by admitting the knowledge of an internal and real world. — Ralph Waldo Emerson

We have done everything within the scope of modern medicine.' Those are just words. They apparently did everything within their erratic knowledge and the limits of their vanity. — Sandor Marai

When my generation grew up, our only sources of knowledge were books, teachers, parents and friends. The encyclopedia was an item of luxury. We faced big limits in what we could learn, where we could be and who we could reach. — Vivek Wadhwa

Believe it or not, the notions of free will and destiny are not mutually exclusive.
Predestination is the universal framework of limits (based on natural physical laws) placed upon us.
Free will is our infinite ability to make choices within that framework.
Because the universal scale is so great - and most of it constitutes an undiscovered frontier - our choices are only limited by our knowledge, our abilities, and our imagination.
To put it simply, the world is such a huge playground sandbox that we will never run out of sand or reach the faraway safety fence of destiny.
So go out there and play! — Vera Nazarian

My path to wisdom began when I stopped pretending to know things I didn't know. When I explicitly admitted to the limits of my knowledge, stopped building on ambiguity and ignorance, and instead realized that I knew nothing, not even the things I thought I knew. — Tucker Max

Freethinkers reject faith as a valid tool of knowledge. Faith is the opposite of reason because reason imposes very strict limits on what can be true, and faith has no limits at all. A Great Escape into faith is no retreat to safety. It is nothing less than surrender. — Dan Barker

Get a millionaire mentor. Most of us were brought up middle class or poor and then hold ourselves to the limits and ideas of that group. I have been studying millionaires to duplicate what they did. Get your own personal millionaire mentor and study them. Most rich people are extremely generous with their knowledge and their resources. — Grant Cardone

It would seem that by our sorrows only are we called to a knowledge of the Infinite. Are we happy? The limits of life constrain us on all sides. — Sophie Swetchine

The one thing we do not know is the limit of the knowable. — Jean-Jacques Rousseau

Schemata are our necessary instruments for making the surfaces of what we read connect significantly with the background knowledge that is wittheld from immediate conciousness by the limits of short-term memory. — E.D. Hirsch Jr.

Oppressive language does more than represent violence; it is violence; does more than represent the limits of knowledge; it limits knowledge. — Toni Morrison

Given the limits of our knowledge of such psychological problems as belief and motivation, the question of sincerity ... is misleading and fruitless. — Donald Weinstein

Truly to realize the ambitions of a science of mind does not solely involve learning about such issues as how we know, perceive and solve problems; it involves finding out tow hat extent the world outside us is knowable by us, and indeed prescribing the limits of inquiry for disciplines like Physics which claim to afford knowledge of the external physical world. — Sean O Nuallain

The task of science is to stake out the limits of the knowable, and to center consciousness within them. — Rudolf Virchow

Anyone who has experienced a strange episode in their life that defies all present scientific knowledge can appreciate the limits of human knowledge. There's nothing like such an event to make you keenly aware of how little we truly know and understand. — Steven Symes

Our power knows no limits, yet we cannot find food for a starving child, or a home for a refugee. Our knowledge is without measure and we build the weapons that will destroy us. We live on the edge of ourselves, terrified of the darkness within. We have harmed, corrupted and ruined, we have made mistakes and deceived. — John Le Carre

It's not always easy to find the motivation to push yourself to higher limits. But when you surround yourself with people who inspire you, you'll find that their attitudes and their outlook on life are contagious. You will learn from their mistakes and their successes. You will gain a wealth of knowledge and wisdom, which will only help you grow and get you closer to your own goals. — Anonymous

Faced with the immensity of the universe, Job realized that there are limits to man's rationalizing, that we cannot find where the cloud of sorrow starts, that all our boasted knowledge is but an island in the vast ocean of mystery, and as the island of knowledge grows larger, the shore line of mystery becomes longer. At the end of his wits, he surrendered in trust to a Higher Wisdom. — Ralph Washington Sockman

Our dreams and imagination set the limits of our achievement. — Debasish Mridha

My father taught me that learning is an endless process, and that there is no limit to the amount of knowledge a person can contain. You are never too old to learn something new, or too young to learn too much. — Suzy Kassem

Cognitive science has something of enormous importance to contribute to human freedom: the ability to learn what our unconscious conceptual systems are like and how our cognitive unconscious functions. If we do not realize that most of our thought is unconscious and that we think metaphorically, we will indeed be slaves to the cognitive unconscious. Paradoxically, the assumption that we have a radically autonomous rationality as traditionally conceived actually limits our rational autonomy. It condemns us to cognitive slavery - to an unaware and uncritical dependence on our unconscious metaphors. To maximize what conceptual freedom we can have, we must be able to see through and move beyond philosophies that deny the existence of an embodied cognitive unconscious that governs most of our mental lives. — George Lakoff

The mind remains undetermined in the great Void. Here the highest knowledge is unbounded. That which gives things their thusness cannot be delimited by things. So when we speak of 'limits', we remain confined to limited things. The limit of the unlimited is called 'fullness.' The limitlessness of the limited is called 'emptiness.' Tao is the source of both. But it is itself neither fullness nor emptiness — Zhuangzi

It is not good for a man to be too cognizant of his physical and spiritual mechanisms. Complete knowledge reveals limits to human possibilities, and the less a man is by nature limited in his purposes, the less he can tolerate limits. — Stanislaw Lem

We are, each of us, alone. And this is the first law of masculinity. And it is the most important law. Your value is equal to the value which you bring to the tribe. We are not equal. You are not special. Respect is earned, not given. Your brothers will not love you unconditionally for who you are, just being yourself. They will criticise you, push you to your limits, bring out the best in you, and give you their respect when earned. And this isn't shocking at all. This is common knowledge to any man. Your childhood is over. The boy is dead. It's time to be a man for the rest of your life. — Jack Donovan

In Darwin's time no serious attempt had been made to examine the manifestations of variability. A vast assemblage of miscellaneous facts could formerly be adduced as seemingly comparable illustrations of the phenomenon "Variation." Time has shown this mass of evidence to be capable of analysis. When first promulgated it produced the impression that variability was a phenomenon generally distributed amongst living things in such a way that the specific divisions must be arbitrary. When this variability is sorted out, and is seen to be in part a result of hybridisation, in part a consequence of the persistence of hybrids by parthenogenetic reproduction, a polymorphism due to the continued presence of individuals representing various combinations of Mendelian allelomorphs, partly also the transient effect of alteration in external circumstances, we see how cautious we must be in drawing inferences as to the indefiniteness of specific limits from a bare knowledge that intermediates exist. — William Bateson

The existence of inherent limits of experience in no way settles the question about the subordination of facts of the human world to our knowledge of matter. — Wilhelm Dilthey

Man is a glorious and unique species of animal. The species originated by evolution.... Future evolution could raise man to superb heights as yet hardly glimpsed, but it will not automatically do so. As far as can now be foreseen, evolutionary degeneration is at least as likely in our future as is further progress.The only way to ensure a progressive evolutionary future for mankind is for man himself to take a hand in the process. Although much further knowledge is needed, it is unquestionably possible for man to guide his own evolution (within limits) along desirable lines. But the great weight of the most widespread...beliefs and institutions is against even attempting such guidance. ["Man's evolutionary future," 1960, p. 134.] — George Gaylord Simpson

Many of the gaps in my knowledge and understanding were simply limits of class and cultural background, not lack of aptitude or application as I feared. Page 135 — Sonia Sotomayor

How would it alter Juliet's love perception to learn the sea is but a rounded jug of water? Would her sensuous analogy turned simple simile unveil to her the limits of herself? Or would she forget the ocean, that deplorable casket, and turn on the true bottomless tumbler, the only running tap: the sky? It may have lost the title 'heavens' when its gods were dethroned, but its infinity reigns. So long as you walk, it reigns. So long as I talk and you listen, there's a voice and ears to keep it active, moving, and reason to say: look! infinity lives. And when we and the other consciousnesses pass, though it in part dies with us, still it reigns. It will, in a sense, plod on, like a lifeless coffin through its own space, sails set for nothing, unstoppable when trailing its fabric. — Richard Ronald Allan

Knowledge, which is power, knows no limits, either in its enslavement of creation or in its deference to worldly masters. — Theodor Adorno

What a misfortune it isto be bornawoman!? Why seek for knowledge, which can prove only that our wretchedness is irremediable? If a ray of light break in upon us, it is but to make darkness more visible; to show usthenew limits, the Gothic structure, theimpenetrable barriers of our prison. — Maria Edgeworth

Theology emerged not as a course of knowledge but as a feast of homily and imagination and exaggeration in which every man could find his image and his portion. And yet there were limits. — Israel Shenker

Too many writers cannot come to terms with the ways in which the past, like the future, is dark. There is so much we don't know, and to write truthfully about a life, your own or your mother's, or a celebrated figure's, an event, a crisis, another culture is to engage repeatedly with those patches of darkness, those nights of history, those places of unknowning. They tell us that there are limits to knowledge, that there are essential mysteries, starting with the notion that we know just what someone thought or felt in the absence of exact information. — Rebecca Solnit

Our life is a short time in expectation, a time in which sadness and joy kiss each other at every moment. There is a quality of sadness that pervades all the moments of our lives. It seems that there is no such thing as a clear-cut pure joy, but that even in the most happy moments of our existence we sense a tinge of sadness. In every satisfaction, there is an awareness of limitations. In every success, there is the fear of jealousy. Behind every smile, there is a tear. In every embrace, there is loneliness. In every friendship, distance. And in all forms of light, there is the knowledge of surrounding darkness ... But this intimate experience in which every bit of life is touched by a bit of death can point us beyond the limits of our existence. It can do so by making us look forward in expectation to the day when our hearts will be filled with perfect joy, a joy that no one shall take away from us. — Henri J.M. Nouwen

The people with this disposition believe that wisdom begins with an awareness of our own ignorance. We can design habits, arrangements, and procedures that partially compensate for the limits on our knowledge. — David Brooks

Then perhaps there is a third kind of loss
the loss that comes when you notice the limits of your knowledge of God, when you feel bereft of guidance, when you feel the loss of God's saving power or of God's grace. This feeling of loss is really a way of noting, and mourning, God's hiddenness. This is the loss you name when you ask why God does not answer your prayers. It is the loss entailed when you realize that Jesus is more mysterious and more inscrutible than you had at first understood. — Lauren F. Winner

There are genuine mysteries in the world that mark the limits of human knowing and thinking. Wisdom is fortified, not destroyed, by understanding its limitations. Ignorance does not make a fool as surely as self-deception. — Mortimer J. Adler

The task of science, therefore, is not to attack the objects of faith, but to establish the limits beyond which knowledge cannot go and found a unified self-consciousness within these limits. — Rudolf Virchow

Scientific knowledge is as much an understanding of the diversity of situations for which a theory or its models are relevant as an understanding of its limits. — Elinor Ostrom

Corporations, in the name of efficiency, suppress variation by "getting all the ducks in line."To optimize productivity, they evolve highly refined and internally consistent operating systems. Payoff - results - as long as the music lasts. But ... all that streamlining and re-engineering limits diversity, suppresses self-organization ... and curtails a bottom up emergent response to disruptive change. — Richard Pascale

... the fabric of family, the limits of love, the loss of innocence and the birth of knowledge. — Betty Smith

My mistake was to project my skill beyond the limits of experience. I began investing outside the I began investing outside of the industries which I believe I thoroughly understood, in completely different spheres of activity; situations where I did not have comparable background knowledge. — Philip Arthur Fisher

The ancient priests had said, "Thus far and no farther. We set the limits to thought." The Greeks said, "All things are to be examined and called into question. There are no limits set to thought." It is an extraordinary fact that by the time we have actual, documentary knowledge of the Greeks there is not a trace to be found of that domination over the mind by the priests which played such a decisive part in the ancient world. The priest plays no real part in either the history or the literature of Greece. — Edith Hamilton

It's a wise man who kens the limits of his knowledge, Ian. — Diana Gabaldon

The great gift of the human imagination is that it has no limits or ending. — Jim Rohn

True wisdom lies in one's confession about the limits of one's knowledge. — Socrates

The single thing which makes any man happiest is the realization that he has worked up to the limits of his ability, his capacity. It's all the better, of course, if this work has made a contribution to knowledge, or toward moving the human race a little farther forward. — Neil Armstrong

Absolute trust in the reality of things begins to be shaken as the problem of truth enters upon the scene. The moment man ceases merely to live in and with reality and demands a knowledge of this reality, he moves into a new and fundamentally different relation to it. At first, to be sure, the question of truth seems to apply only to particular parts and not to the whole of reality. Within this whole different strata of validity begin to be marked off, reality seems to separate sharply from appearance. But it lies in the very nature of the problem of truth that once it arises it never comes to rest. The concept of truth conceals an immanent dialectic that drives it inexorably forward, forever extending its limits. — Ernst Cassirer

The recognition of the insuperable limits to his knowledge ought indeed to teach the student of society a lesson of humility which should guard him against becoming an accomplice in men's fatal striving to control society - a striving which makes him not only a tyrant over his fellows, but which may well make him the destroyer of a civilization which no brain has designed but which has grown from the free efforts of millions of individuals. — Friedrich Hayek

The end of man is God, an end obviously exceeding the limits of reason. Yet man should have some knowledge of his end in order to regulate and order his intentions and actions towards that end. The salvation of man, therefore, demands that divine revelation should make him know a certain number of truths quite beyond the grasp of his reason.43 In other words, since man requires knowledge of the infinite God, who is his end, and since such knowledge exceeds the limits of his reason, he simply must get it by way of faith. Nor does such faith do violence to our reason. Rather, faith in the incomprehensible confers on rational knowledge its perfection and consummation. — Etienne Gilson

I like the notion of stubborn incuriosity. To cultivate a stubborn incuriosity, you have to limit yourself to certain areas of knowledge. You cannot be totally greedy. You have to oblige yourself not to learn everything. Or else you will learn nothing. — Umberto Eco

The world needs the kind of education by means of which character is formed, strength of the mind is increased and the human intellect is expanded beyond its own limits. — Abhijit Naskar

The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge. — Charles Sanders Peirce
