Quotes & Sayings About Knowledge Aristotle

What I find in Aristotle is mainly a quite dull collection of generalizations, many of which seem impossible to justify in the light of modern knowledge, — Robert M. Pirsig

It is easy to understand that in the dreary middle ages the Aristotelian logic would be very acceptable to the controversial spirit of the schoolmen, which, in the absence of all real knowledge, spent its energy upon mere formulas and words, and that it would be eagerly adopted even in its mutilated Arabian form, and presently established as the centre of all knowledge. — Arthur Schopenhauer

A right election can only be made by those who have knowledge; — Aristotle.

Hence the young man is not a fit student of Moral Philosophy, for he has no experience in the actions of life, while all that is said presupposes and is concerned with these: and in the next place, since he is apt to follow the impulses of his passions, he will hear as though he heard not, and to no profit, the end in view being practice and not mere knowledge. And I draw no distinction between young in years, and youthful in temper and disposition: the defect to which I allude being no direct result of the time, but of living at the beck and call of passion, and following each object as it rises. For to them that are such the knowledge comes to be unprofitable, as to those of imperfect self-control: — Aristotle.

I see that you have hitherto been one of that herd who, in order to learn how matters such as this take place, and in order to acquire a knowledge of natural effects, do not exhaust themselves in waking and studying, and mortify themselves with experiments and observations, but retire into their studies and glance through an index and a table of contents to see whether Aristotle has said any thing about them; and, being assured of the true sense of his text, consider that nothing else can be known. — Galileo Galilei

I am certainly open to the idea that this might be used to explain other philosophical categories besides knowledge. I have some real sympathy with the work of those moral realists who have tried to give naturalistic accounts of human flourishing, and who offer accounts of right action in such terms. (I suppose this is more evidence that I really do have deep affinities with Aristotle!) — Hilary Kornblith

For imitation is natural to man from his infancy. Man differs from other animals particularly in this, that he is imitative, and acquires his rudiments of knowledge in this way; besides, the delight in it is universal. — Aristotle.

Live as if you are the Jesus and learn as if you are the Aristotle. — Debasish Mridha

For knowing is spoken of in three ways: it may be either universal knowledge or knowledge proper to the matter in hand or actualising such knowledge; consequently three kinds of error also are possible. — Aristotle.

Art is a higher type of knowledge than experience. — Aristotle.

To attain any assured knowledge about the soul is one of the most difficult things in the world. — Aristotle.

Rhetoric is the counterpart of logic; since both are conversant with subjects of such a nature as it is the business of all to have a certain knowledge of, and which belong to no distinct science. Wherefore all men in some way participate of both; since all, to a certain extent, attempt, as well to sift, as to maintain an argument; as well to defend themselves, as to impeach. — Aristotle.

What we know is not capable of being otherwise; of things capable of being otherwise we do not know, when they have passed outsideour observation, whether they exist or not. Therefore the object of knowledge is of necessity. Therefore it is eternal; for things that are of necessity in the unqualified sense are all eternal; and things that are eternal are ungenerated and imperishable. — Aristotle.

All men naturally desire knowledge. An indication of this is our esteem for the senses; for apart from their use we esteem them for their own sake, and most of all the sense of sight. Not only with a view to action, but even when no action is contemplated, we prefer sight, generally speaking, to all the other senses. The reason of this is that of all the senses sight best helps us to know things, and reveals many distinctions. — Aristotle.

Metaphysics involves intuitive knowledge of unprovable starting-points concepts and truth and demonstrative knowledge of what follows from them. — Aristotle.

It will contribute towards one's object, who wishes to acquire a facility in the gaining of knowledge, to doubt judiciously. — Aristotle.

Aristotle described the Crow as chaste. In some departments of knowledge, Aristotle was too innocent for his own good. — Will Cuppy

Actual knowledge is identical with its object: in the individual, potential knowledge is in time prior to actual knowledge, but in the universe as a whole it is not prior even in time. Mind is not at one time knowing and at another not. When mind is set free from its present conditions it appears as just what it is and nothing more: this alone is immortal and eternal (we do not, however, remember its former activity because, while mind in this sense is impassible, mind as passive is destructible), and without it nothing thinks. — Aristotle.

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

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

How can a man know what is good or best for him, and yet chronically fail to act upon his knowledge? — Aristotle.

For to people of that sort, just as to those lacking self-restraint,15 knowledge is without benefit. But to those who fashion their longings in accord with reason and act accordingly, knowing about these things would be of great profit. — Aristotle.

We need both Socrates and Aristotle in the search for knowledge, but in education today there is too much Aristotle and too little Socrates. — Gregory J.E. Rawlins

The intelligence consists not only in the knowledge but also in the skill to apply the knowledge into practice. — Aristotle.

There are branches of learning and education which we must study merely with a view to leisure spent in intellectual activity, and these are to be valued for their own sake; whereas those kinds of knowledge which are useful in business are to be deemed necessary, and exist for the sake of other things. — Aristotle.

Only a few of us retain a childlike wonder throughout our lives. A typical life's journey is one with increasing knowledge but decreasing mental and physical adaptability. Our mindset unknowingly gets trapped in conceptions and categories that we create. As Aristotle observed, as we grow older, we aspire to nothing great and exalted and crave the mere necessities and comforts of existence. Age is a very high price to pay for maturity. — Ted Chu

Saying the words that come from knowledge is no sign of having it. — Aristotle.

Thomas Aquinas said of suffering, as Aristotle had said of shame, that it was a thing not good in itself; but a thing which might have a certain goodness in particular circumstances. That is to say, if evil is present, pain at recognition of the evil, being a kind of knowledge, is relatively good. — C.S. Lewis

It is this simplicity that makes the uneducated more effective than the educated when addressing popular audiences - makes them, as the poets tell us, 'charm the crowd's ears more finely.' Educated men lay down broad general principles; uneducated men argue from common knowledge and draw obvious conclusions. — Aristotle.

The one exclusive sign of thorough knowledge is the power of teaching. — Aristotle.

There is only one good, that is knowledge; there is only one evil, that is ignorance. — Aristotle.

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

The ultimate end ... is not knowledge, but action. To be half right on time may be more important than to obtain the whole truth too late. — Aristotle.

The wise man knows of all things, as far as possible, although he has no knowledge of each of them in detail — Aristotle.

Rhetoric is useful because the true and the just are naturally superior to their opposites, so that, if decisions are improperly made, they must owe their defeat to their own advocates; which is reprehensible. Further, in dealing with certain persons, even if we possessed the most accurate scientific knowledge, we should not find it easy to persuade them by the employment of such knowledge. For scientific discourse is concerned with instruction, but in the case of such persons instruction is impossible. — Aristotle.

[Thomas Henry] Huxley, I believe, was the greatest Englishman of the Nineteenth Century - perhaps the greatest Englishman of all time. When one thinks of him, one thinks inevitably of such men as Goethe and Aristotle. For in him there was that rich, incomparable blend of intelligence and character, of colossal knowledge and high adventurousness, of instinctive honesty and indomitable courage which appears in mankind only once in a blue moon. There have been far greater scientists, even in England, but there has never been a scientist who was a greater man. — H.L. Mencken

It is not easy to determine the nature of music, or why any one should have a knowledge of it. — Aristotle.

Alexander the Great valued learning so highly, that he used to say he was more indebted to Aristotle for giving him knowledge than to his father Philip for life. — Samuel Smiles

When the point of education becomes the production of credentials rather than the cultivation of knowledge, it forfeits the motive recognized by Aristotle: All human beings by nature desire to know. — Matthew B. Crawford

All teaching and all intellectual learning come about from already existing knowledge. — Aristotle.

Knowledge of the fact differs from knowledge of the reason for the fact. — Aristotle.

In practical matters the end is not mere speculative knowledge of what is to be done, but rather the doing of it. It is not enough to know about Virtue, then, but we must endeavor to possess it, and to use it, or to take any other steps that may make. — Aristotle.

Even subjects that are known are known only to a few — Aristotle.

Beside these there is no other way; for the act is necessarily either done or not done, and those who act either have knowledge or do not. — Aristotle.

All men by nature desire knowledge. — Aristotle.

Some things the legislator must find ready to his hand in a state, others he must provide. And therefore we can only say: May our state be constituted in such a manner as to be blessed with the goods of which fortune disposes (for we acknowledge her power): whereas virtue and goodness in the state are not a matter of chance but the result of knowledge and purpose. A city can be virtuous only when the citizens who have a share in the government are virtuous, and in our state all the citizens share in the government; — Aristotle.

I have often wondered and even laughed at those who fancied that everything had been so consummately and absolutely investigated by an Aristotle or a Galen or some other mighty name, that nothing could by any possibility be added to their knowledge. — William Harvey

As we understand philosophy today, we often think of the works of Europeans, who often associate philosophy themselves to Greece and Rome and totally ignoring the true source of the knowledge of the Greeks such as Aristotle, Socrates and Plato, whose references to Africa and Egypt and Nubia can fill up more tomes than have already been presented to us. And — Uwa Afu

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

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.

even if we possessed the most accurate scientific knowledge, we should not find it easy to persuade them by the employment of such knowledge. For scientific discourse is concerned with instruction, but in the case of such persons instruction is impossible; our proofs and arguments must rest on generally accepted principles, as we said in the Topics, when speaking of converse with the multitude. — Aristotle.

Plato would hardly need to change a single word of his myth of the cave. Our knowledge would not be able to furnish an answer to his anxiety, his disquietude, his "premonitions." The world would remain for him, "in the light" of our "positive" sciences, what it was - a dark and sorrowful subterranean region - and we would seem to him like chained prisoners. Life would again have to make superhuman efforts, "as in a battle," to break open for himself a path through the truths created by the sciences which "dream of being but cannot see it in waking reality." [1] In brief, Aristotle would bless our knowledge while Plato would curse it. — Lev Shestov

The knowledge of the soul admittedly contributes greatly to the advance of truth in general, and, above all, to our understanding of Nature, for the soul is in some sense the principle of animal life. — Aristotle.

If Aristotle and his pupil Alexander the Great were brought back to life today, they would believe themselves in the country of the gods and not of men. Ten lives would not suffice Aristotle to assimilate all the knowledge that has been accumulated on earth since his death, and Alexander would perhaps be able to realize his dream and conquer the world. — Lev Shestov

In one of Plato's seminars a young man with a rural accent stood up one day and said Plato's philosophy was nonsense. You can have ideas that are neither real nor permanent. They can be mere fleeting fantasies. Plato evicted the student, whose name was Aristotle. Unlike Plato, Aristotle was not one of the gilded youth of Athenian society. His social background was solid middle class. But such was the encyclopedic knowledge he came to exhibit, and his skill in logical argument, that in time Aristotle gained rich benefactors, including the king of Macedonia who hired Aristotle to tutor his young son, later known as Alexander the Great. — Norman F. Cantor

A young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end that is aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character. — Aristotle.

Because in life, knowledge is only part of the battle. WITHOUT ACTION, KNOWLEDGE IS OFTEN MEANINGLESS. As Aristotle put it, to be excellent we cannot simply think or feel excellent, we must act excellently. Yet the action required to follow through on what we know is often the hardest part. — Shawn Achor

Hence a young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character; the defect does not depend on time, but on his living, and pursuing each successive object, as passion directs. For to such persons, as to the incontinent, knowledge brings no profit; but to those who desire and act in accordance with a rational principle knowledge about such matters will be of great benefit. — Aristotle.

If there is some end of the things we do, which we desire for its own sake, clearly this must be the good. Will not knowledge of it, then, have a great influence on life? Shall we not, like archers who have a mark to aim at, be more likely to hit upon what we should? If so, we must try, in outline at least, to determine what it is. — Aristotle.

Intuition is the source of scientific knowledge. — Aristotle.

At first he who invented any art that went beyond the common perceptions of man was naturally admired by men, not only because there was something useful in the inventions, but because he was thought wise and superior to the rest. But as more arts were invented, and some were directed to the necessities of life, others to its recreation, the inventors of the latter were always regarded as wiser than the inventors of the former, because their branches of knowledge did not aim at utility. — Aristotle.

From Hinduism to the monotheisms through to Socrates, Plato and Aristotle, the common message is that we are all, naturally and potentially, inclined to reject the other, and to be intolerant and racist. Left to our own devices and our own emotions, we can be deaf, blind, dogmatic, closed and xenophobic: we are not born open-minded, respectful and pluralist. We become so through personal effort, education, self-mastery and knowledge. — Tariq Ramadan

The purpose of the present study is not as it is in other inquiries, the attainment of knowledge, we are not conducting this inquiry in order to know what virtue is, but in order to become good, else there would be no advantage in studying it. For that reason, it becomes necessary to examine the problem of our actions and to ask how they are to be performed. For as we have said, the actions determine what kind of characteristics are developed. — Aristotle.

The Greeks, as in the case of Aristotle, whose interpretation of African teachings would, some have said, lead to the foundation of Islam as as a religion, would steal what texts they could, burn the rest and destroy the very place from which all knowledge first came from. — Rick Duncan

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

Art completes what nature cannot bring to finish. The artist gives us knowledge of nature's unrealized ends. — Aristotle.

The business of an animal is not only to reproduce (which is common to all living things), but they all of them also participate in a kind of knowledge (some more, some less, some very little indeed), because they have sense-perception, which is a kind of knowledge. But the worth we assign it hinges on whether we look at it compared with intelligence or with the class of lifeless things. Compared with intelligence it seems like almost nothing to have a share of touch and taste alone, but compared with the absence of all sensation it appears a great thing. For even this form of knowledge would appear a precious thing compared with lying in a state of death or of nonexistence. - Aristotle, Generation of Animals — Michael Augros

In the case of some people, not even if we had the most accurate scientific knowledge, would it be easy to persuade them were we to address them through the medium of that knowledge; for a scientific discourse, it is the privilege of education to appreciate, and it is impossible that this should extend to the multitude. — Aristotle.

So it happens that we must ask ourselves, with regard to truth, not for a new criterion for it, which will be better polished than earlier ones, but, peremptorily and seizing it by the lapels, "what is truth as such," and with regard to reality, not what things are or what and how is that which is, but for what reason that X which we call Being is in the Universe, and with regard to knowledge we must not ask for its bases and limits - as Plato, Aristotle Descartes, Kant did - but for something which comes before all this: for what reason we concern ourselves with trying to know. — Jose Ortega Y Gasset

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.

The truth is that science started its modern career by taking over ideas derived from the weakest side of the philosophies of Aristotle's successors. In some respects it was a happy choice. It enabled the knowledge of the seventeenth century to be formularised so far as physics and chemistry were concerned, with a completeness which has lasted to the present time. But the progress of biology and psychology has probably been checked by the uncritical assumption of half-truths. If science is not to degenerate into a medley of ad hoc hypothesis, it must become philosophical and must enter upon a thorough criticism of its own foundations. — Alfred North Whitehead
