Plato Self Knowledge Quotes & Sayings

In the world of knowledge, the idea of good appears last of all, and is seen only with effort. — Plato

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

The good repent on knowing their sin; the evil become angry when discovered. Ignorance is not the cause of evil, as Plato held; neither is education the answer to the removal of evil. These men had an intellect as well as a will; knowledge as well as intention. Truth can be known and hated; Goodness can be known and crucified. The Hour was approaching, and for the moment the fear of the people deterred the Pharisees. Violence could not be triggered against Him until He would say, 'This is your Hour. — Fulton J. Sheen

So the state founded on natural principles is wise as a whole in virtue of the knowledge inherent in its smallest constituent class, which exercises authority over the rest. And the smallest class is the one which naturally possesses that form of knowledge which alone of all others deserves the title of wisdom. — Plato

Knowledge without justice ought to be called cunning rather than wisdom. — Plato

Then, when the rhetorician is more persuasive than the physician, the ignorant is more persuasive with the ignorant than he who has knowledge? - is not that the inference? — Plato

Sartre, in his memoirs, confessed to much the same experience. Like Plato, I passed from knowledge to its subject. I found more reality in the idea than in the thing because it was given to me first and because it was given for a thing. It was in books that I encountered the universe: digested, classified, labelled, mediated, still formidable. — Alberto Manguel

Whereas, our argument shows that the power and capacity of learning exists in the soul already; and that just as the eye was unable to turn from darkness to light without the whole body, so too the instrument of knowledge can only by the movement of the whole soul be turned from the world of becoming into that of being, and learn by degrees to endure the sight of being, and of the brightest and best of being, or in other words, of the good. — Plato

Plato's sense that this was the only religion that would hold up nowadays was thoroughgoing. The only religion that could be really believed by anyone in his time, he said, is based on belief that the stars have intelligence, and that we and they have immortal souls of some sort.18 The more we learn - and mathematics is the queen of the soul's subjects - the more we will ascend toward self-knowledge and universal truth. This ascension is the drama of Plato's religion. — Jennifer Michael Hecht

Haven't you noticed that opinion without knowledge is always a poor thing? At the best it is blind - isn't anyone who holds a true opinion without understanding like a blind man on the right road? — Plato

The choice of souls was in most cases based on their own experience of a previous life ... Knowledge easily acquired is that which the enduing self had in an earlier life, so that it flows back easily. — Plato

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

Knowledge of the soul is the only universal truth and the only wisdom - all other knowledge is transient. — Plato

Knowledge is the rediscovering of our own insight. — Plato

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

And all knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom; wherefore make this your first and last and constant and all-absorbing aim, to exceed, if possible, not only us but all your ancestors in virtue; and know that to excel you in virtue only brings us shame, but that to be excelled by you is a source of happiness to us. — Plato

The essence of knowledge is self-knowledge, — Plato

Moderation, which consists in indifference about little things, and in a prudent and well-proportioned zeal about things of importance, can proceed from nothing but true knowledge, which has its foundation in self-acquaintance. — Plato

Solomon saith: There is no new thing upon
the earth. So that as Plato had an imagination,
that all knowledge was but remembrance; so
Solomon giveth his sentence, that all novelty is
but oblivion.
Francis Bacon: Essays, LVIII — Jorge Luis Borges

Knowledge unqualified is knowledge simply of something learned. — Plato

Plato believed that insanity was essential to our nature and assumed that it held esoteric knowledge about who we are. — Michael Greenberg

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

Conversation. In Laches, he discusses the meaning of courage with a couple of retired generals seeking instruction for their kinsmen. In Lysis, Socrates joins a group of young friends in trying to define friendship. In Charmides, he engages another such group in examining the widely celebrated virtue of sophrosune, the "temperance" that combines self-control and self-knowledge. (Plato's readers would know that the bright young man who gives his name to the latter dialogue would grow up to become one of the notorious Thirty Tyrants who briefly ruled Athens after its defeat by Sparta in the Peloponnesian War.) None of these dialogues reaches definite conclusions. They end in aporia, contradictions or other difficulties. The Socratic dialogues are aporetic: his interlocutors are left puzzled about what they thought they knew. Socrates's cross-examination, or elenchus, exposes their ignorance, but he exhorts his fellows to — Plato

Modern man, seeking a middle position in the evaluation of sense impression and thought, can, following Plato , interpret the process of understanding nature as a correspondence, that is, a coming into congruence of pre-existing images of the human psyche with external objects and their behaviour. Modern man, of course, unlike Plato , looks on the pre-existent original images also as not invariable, but as relative to the development of a conscious point of view, so that the word "dialectic" which Plato is fond of using may be applied to the process of development of human knowledge. — Wolfgang Pauli

This was her original state; and then, as I was saying, and as the lovers of knowledge are well aware, philosophy, seeing how terrible was her confinement, of which she was to herself the cause, received and gently comforted her and sought to release her, pointing out that the eye and the ear and the other senses are full of deception, and persuading her to retire from them, and abstain from all but the necessary use of them, and be gathered up and collected into herself, bidding her trust in herself and her own pure apprehension of pure existence, and to mistrust whatever comes to her through other channels and is subject to variation; for such things are visible and tangible, but what she sees in her own nature is intelligible and invisible. — Plato

If anyone comes to the gates of poetry and expects to become an adequate poet by acquiring expert knowledge of the subject without the Muses' madness, he will fail, and his self-controlled verses will be eclipsed by the poetry of men who have been driven out of their minds. — Plato

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

Knowledge becomes evil if the aim be not virtuous. — Plato

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

GUARD YOUR WEAK POINT. He that is slow to anger is better than the mighty: and he that ruleth his spirit than he that taketh a city. - Bible. The first and best of victories is for a man to conquer himself: to be conquered by himself is, of all things, the most shameful and vile. - Plato. The worst education which teaches self-denial is better than the best which teaches everything else and not that. - John Sterling. Most powerful is he who has himself in his own power. - Seneca. The energy which issues in growth, or assimilates knowledge, must originate in self and be self-directed. - Thomas J. Morgan. — Orison Swett Marden

The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know. — Plato

The only real ill-doing is the deprivation of knowledge. — Plato

But progress in knowledge has made us aware of the superficiality of Plato's lumping of individuals and their original powers into a few sharply marked-off classes; it has taught us that original capacities are indefinitely numerous and variable. It is but the other side of this fact to say that in the degree in which society has become democratic, social organization means utilization of the specific and variable qualities of individuals, not stratification by classes. — John Dewey

True opinions are a fine thing and do all sorts of good so long as they stay in their place; but they will not stay long. They run away from a man's mind, so they are not worth much until you tether them by working out the reason. Once they are tied down, they become knowledge, and are stable. — Plato

Self-love is the source of that ignorant conceit of knowledge which is always doing and never succeeding. — Plato

Then you will make a law that they shall have such an education as will enable them to attain the greatest skill in asking and answering questions? Yes, he said, you and I together will make it. Dialectic, then, as you will agree, is the coping-stone of the sciences, and is set over them; no other science can be placed higher - the nature of knowledge can no further go? I agree, he said. But to whom we — Plato

In my freshman and sophomore years of college, I read dozens of books by the great thinkers of Western civilization. From Plato to Nietzsche, Homer to Shakespeare - you name it, I read it. At times it drove me crazy - picture reading hundreds of pages that sound like this every week: "All rational knowledge is either material and concerned with some object, or formal and concerned only with the form of understanding and of reason themselves and with the universal rules of thought in general without regard to differences of its objects." Come again, Kant? — Stefanie Weisman

Entire ignorance is not so terrible or extreme an evil, and is far from being the greatest of all; too much cleverness and too much learning, accompanied with ill bringing-up, are far more fatal. — Plato

I should not like to say ... that any kind of knowledge is not to be learned; for all knowledge appears to be a good. — Plato

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

Salomon saith, There is no new thing upon the earth. So that as Plato had an imagination, that all knowledge was but remembrance; so Salomon giveth his sentence, that all novelty is but oblivion. — Francis Bacon

According to Plato, Socrates believed all knowledge came from a divine state, but humans had forgotten it. Most lived in a cave of ignorance, but one could become enlightened by climbing out of the darkness and understanding the divide between the spiritual and material planes. — Gwendolyn Womack

All knowledge is but remembrance. — Plato

Then we shan't regard anyone as a lover of knowledge or wisdom who is fussy about what he studies ... — Plato

The learning and knowledge that we have, is, at the most, but little compared with that of which we are ignorant. — Plato

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

A library of wisdom, is more precious than all wealth, and all things that are desirable cannot be compared to it. Whoever therefore claims to be zealous of truth, of happiness, of wisdom or knowledge, must become a lover of books. — Plato
