(1) The readiness acquired by previous training conduces much to the perception of such things as are requisite; but those things which can be perceived only by mind are the special exercise for the mind. And their nature is triple according as we consider their quantity, their magnitude, and what can be predicated of them. For the discourse which consists of demonstrations, implants in the spirit of him who follows it, clear faith; so that he cannot conceive of that which is demonstrated being different; and so it does not allow us to succumb to those who assail us by fraud. In such studies, therefore, the soul is purged from sensible things, and is excited, so as to be able to see truth distinctly. For nutriment, and the training which is maintained gentle, make noble natures I; and noble natures, when they have received such training, become still better than before both in other respects, but especially in productiveness, as is the case with the other creatures. Wherefore it is mid, "Go to the ant, thou sluggard, and become wiser than it, which provideth much and, varied food in the harvest against the inclemency of winter." Or go to the bee, and learn how laborious she is; for she, feeding on the whole meadow, produces one honey-comb.

(1) For to him knowledge (gnosis) is the principal thing. Consequently, therefore, he applies to the subjects that are a training for knowledge, taking from each branch of study its contribution to the truth. Prosecuting, then, the proportion of harmonies in music; and in arithmetic noting the increasing and decreasing of numbers, and their relations to one another, and how the most of things fall under some proportion of numbers; studying geometry, which is abstract essence, he perceives a continuous distance, and an immutable essence which is different from these bodies. And by astronomy, again, raised from the earth in his mind, he is elevated along with heaven, and will revolve with its revolution; studying ever divine things, and their harmony with each other; from which Abraham starting, ascended to the knowledge of Him who created them.

(9) ’Tis mind that all things sees and hears;

What else exists is deaf and blind.

But the precept which is next to this in efficacy is that which exhorts to be beyond measure studious of purifying the intellect, and by various methods adapting it through mathematical orgies to receive something divinely beneficial, so as neither to fear a separation from body, nor, when led to incorporeal natures, to be forced to turn away the eyes, through their most refulgent splendor, nor to be converted to those passions which nail and fasten the soul to the body. And, in short, which urges the soul to be untamed by all those passions which are the progeny of the realms of generation, and which draw it to an inferior condition of being. For the exercise and ascent through all these, is the study of the most perfect fortitude. And such are the instances adduced by us of the fortitude of Pythagoras, and the Pythagoreans.

(531) regard the skilled mathematician as a dialectician? Assuredly not, he said; I have hardly ever known a mathematician who was capable of reasoning. But do you imagine that men who are unable to give and take a reason will have the knowledge which we require of them? Neither can this be supposed. And so, Glaucon, I said, we have at last arrived at the hymn of dialectic. This is that strain which is of the intellect only, but which the faculty of sight will nevertheless be found to imitate; for sight, as you may remember, was imagined by us after a while to behold the real animals and stars, and last of all the sun himself. And so with dialectic; when a person starts on the discovery of the absolute by the light of reason only, and without any assistance of sense, and perseveres until by pure intelligence he arrives at the perception of the absolute good, he at last finds himself at the end of the intellectual world, as in the case of sight at the end of the visible. Exactly, he said. Then this is the progress which you call dialectic? True. But the release of the prisoners from chains, and their translation from the shadows to the images and to the light, and the ascent from the underground den to the sun, while in his presence they are vainly trying to look on animals and plants and the light of the sun, but are able to perceive

(13) In scientific matters, as being alone possessed of scientific knowledge, he will hold the pre-eminence, and will discourse on the discussion respecting the good, ever intent on intellectual objects, tracing out his procedure in human affairs from the archetypes above; as navigators direct the ship according to the star; prepared to hold himself in readiness for every suitable action; accustomed to despise all difficulties and dangers when it is necessary to undergo them; never doing anything precipitate or incongruous either to himself or the common weal; fore-seeing; and inflexible by pleasures both of waking hours and of dreams. For, accustomed to spare living and frugality, he is moderate, active, mad grave; requiring few necessaries for life; occupying himself with nothing superfluous. But desiring not even these things as chief, but by reason of fellowship in life, as necessary for his sojourn in life, as far as necessary.

(18) In a civilization primarily concerned with the accomplishment of the extremes of temporal activity, the philosopher represents an equilibrating intellect capable of estimating and guiding the cultural growth. The establishment of the philosophic rhythm in the nature of an individual ordinarily requires from fifteen to twenty years. During that entire period the disciples of old were constantly subjected to the most severe discipline. Every activity of life was gradually disengaged from other interests and focalized upon the reasoning part. In the ancient world there was another and most vital factor which entered into the production of rational intellects and which is entirely beyond the comprehension of modern thinkers: namely, initiation into the philosophic Mysteries. A man who had demonstrated his peculiar mental and spiritual fitness was accepted into the body of the learned and to him was revealed that priceless heritage of arcane lore preserved from generation to generation. This heritage of philosophic truth is the matchless treasure of all ages, and each disciple admitted into these brotherhoods of the wise made, in turn, his individual contribution to this store of classified knowledge.

(535) Further, he of whom we are in search should have a good memory, and be an unwearied solid man who is a lover of labour in any line; or he will never be able to endure the great amount of bodily exercise and to go through all the intellectual discipline and study which we require of him. Certainly, he said; he must have natural gifts. The mistake at present is, that those who study philosophy have no vocation, and this, as I was before saying, is the reason why she has fallen into disrepute: her true sons should take her by the hand and not bastards. What do you mean? In the first place, her votary should not have a lame or halting industry—I mean, that he should not be half industrious and half idle: as, for example, when a man is a lover of gymnastic and hunting, and all other bodily exercises, but a hater rather than a lover of the labour of learning or listening or enquiring. Or the occupation to which he devotes himself may be of an opposite kind, and he may have the other sort of lameness. Certainly, he said. And as to truth, I said, is not a soul equally to be deemed halt and lame which hates voluntary falsehood and is extremely indignant at herself and others when they tell lies, but is patient of involuntary falsehood, and does not mind wallowing like a swinish beast in the mire of ignorance, and has no shame at being detected? To be sure.

(525) And they appear to lead the mind towards truth? Yes, in a very remarkable manner. Then this is knowledge of the kind for which we are seeking, having a double use, military and philosophical; for the man of war must learn the art of number or he will not know how to array his troops, and the philosopher also, because he has to rise out of the sea of change and lay hold of true being, and therefore he must be an arithmetician. That is true. And our guardian is both warrior and philosopher? Certainly. Then this is a kind of knowledge which legislation may fitly prescribe; and we must endeavour to persuade those who are to be the principal men of our State to go and learn arithmetic, not as amateurs, but they must carry on the study until they see the nature of numbers with the mind only; nor again, like merchants or retail-traders, with a view to buying or selling, but for the sake of their military use, and of the soul herself; and because this will be the easiest way for her to pass from becoming to truth and being. That is excellent, he said. Yes, I said, and now having spoken of it, I must add how charming the science is! and in how many ways it conduces to our desired end, if pursued in the spirit of a philosopher, and not of a shopkeeper! How do you mean? I mean, as I was saying, that arithmetic has a very great and elevating effect, compelling the soul to reason about abstract number, and rebelling against the introduction of visible or tangible objects into the argument. You know

(2) But indications of this theory worthy of notice may be mentioned, by which it is possible for you, and those who resemble you, to be conducted by intellect to the essence of [real] beings. And with respect to such things as become known by a reasoning process, we shall leave no one of these without a perfect demonstration. But in all things we shall give to each that which is appropriate. And such questions, indeed, as are theological, we shall answer theologically; such as are theurgic, theurgically; but such as are philosophical, we shall, in conjunction with you, philosophically explore. Of these, also, such as extend to first causes, we shall unfold into light, by following them conformably to first principles. But such as pertain to morals, or to ends, we shall fitly discuss, according to the ethical mode. And, in a similar manner, we shall examine other things methodically and appropriately. Let us, therefore, now betake ourselves to your inquiries.

(533) Dear Glaucon, I said, you will not be able to follow me here, though I would do my best, and you should behold not an image only but the absolute truth, according to my notion. Whether what I told you would or would not have been a reality I cannot venture to say; but you would have seen something like reality; of that I am confident. Doubtless, he replied. But I must also remind you, that the power of dialectic alone can reveal this, and only to one who is a disciple of the previous sciences. Of that assertion you may be as confident as of the last. And assuredly no one will argue that there is any other method of comprehending by any regular process all true existence or of ascertaining what each thing is in its own nature; for the arts in general are concerned with the desires or opinions of men, or are cultivated with a view to production and construction, or for the preservation of such productions and constructions; and as to the mathematical sciences which, as we were saying, have some apprehension of true being—geometry and the like—they only dream about being, but never can they behold the waking reality so long as they leave the hypotheses which they use unexamined, and are unable to give an account of them. For when a man knows not his own first principle, and when the conclusion and intermediate steps are also constructed out of he knows not what, how can he imagine that such a fabric of convention can ever become science? Impossible, he said. Then dialectic, and dialectic alone, goes directly to the first principle and is the only science which does away with hypotheses in order to make her ground secure; the eye of

(490) which is an appearance only, but will go on—the keen edge will not be blunted, nor the force of his desire abate until he have attained the knowledge of the true nature of every essence by a sympathetic and kindred power in the soul, and by that power drawing near and mingling and becoming incorporate with very being, having begotten mind and truth, he will have knowledge and will live and grow truly, and then, and not till then, will he cease from his travail. Nothing, he said, can be more just than such a description of him. And will the love of a lie be any part of a philosopher’s nature? Will he not utterly hate a lie? He will. And when truth is the captain, we cannot suspect any evil of the band which he leads? Impossible. Justice and health of mind will be of the company, and temperance will follow after? True, he replied. Neither is there any reason why I should again set in array the philosopher’s virtues, as you will doubtless remember that courage, magnificence, apprehension, memory, were his natural gifts. And you objected that, although no one could deny what I then said, still, if you leave words and look at facts, the persons who are thus described are some of them manifestly useless, and the greater number utterly depraved; we were then led to enquire into the grounds of these accusations, and have now arrived at the point of asking why are the majority bad, which question of necessity brought us back to the examination and definition of the true philosopher.

(1) The prudent [i. e. the wise] man will especially become so as follows: In the first place, being naturally sagacious, possessing a good memory, and being a lover of labor, he should exercise his dianoetic power immediately from his youth in reasonings and disciplines, and in accurate theories, and adhere to genuine philosophy. But after this he should acquire knowledge and experience in what pertains to the Gods, the laws, and human lives. For there are two things from which the disposition of prudence is produced; one of which consists in obtaining a mathematical and gnostic habit; but the other, in a man perceiving by himself many theorems and things, and understanding other things through a certain different mode. For neither is he sufficient to the possession of prudence, who immediately from his youth has exercised his dianoetic power in reasonings and disciplines; nor he who being destitute of these, has heard and has been conversant with a multitude of things.

But the latter will have his dianoetic power blind, through judging of particulars; and the former through always surveying universals. For as in computations the amount of the whole is obtained by the addition of the parts, thus also in things, reason is able to delineate the theory of universals; but experience has the power of forming a judgment of particulars.

(532) even with their weak eyes the images 6 in the water (which are divine), and are the shadows of true existence (not shadows of images cast by a light of fire, which compared with the sun is only an image)—this power of elevating the highest principle in the soul to the contemplation of that which is best in existence, with which we may compare the raising of that faculty which is the very light of the body to the sight of that which is brightest in the material and visible world—this power is given, as I was saying, by all that study and pursuit of the arts which has been described. I agree in what you are saying, he replied, which may be hard to believe, yet, from another point of view, is harder still to deny. This, however, is not a theme to be treated of in passing only, but will have to be discussed again and again. And so, whether our conclusion be true or false, let us assume all this, and proceed at once from the prelude or preamble to the chief strain 7 , and describe that in like manner. Say, then, what is the nature and what are the divisions of dialectic, and what are the paths which lead thither; for these paths will also lead to our final rest.

(486) Then a soul which forgets cannot be ranked among genuine philosophic natures; we must insist that the philosopher should have a good memory? Certainly. And once more, the inharmonious and unseemly nature can only tend to disproportion? Undoubtedly. And do you consider truth to be akin to proportion or to disproportion? To proportion. Then, besides other qualities, we must try to find a naturally well-proportioned and gracious mind, which will move spontaneously towards the true being of everything. Certainly. Well, and do not all these qualities, which we have been enumerating, go together, and are they not, in a manner, necessary to a soul, which is to have a full and perfect participation of being? They are absolutely necessary, he replied. And must not that be a blameless study which he only can pursue who has the gift of a good memory, and is quick to learn,—noble, gracious, the friend of truth, justice, courage, temperance, who are his kindred? The god of jealousy himself, he said, could find no fault with such a study. And to men like him, I said, when perfected by years and education, and to these only you will entrust the State.

(527) Yes, that is what we assert. Yet anybody who has the least acquaintance with geometry will not deny that such a conception of the science is in flat contradiction to the ordinary language of geometricians. How so? They have in view practice only, and are always speaking, in a narrow and ridiculous manner, of squaring and extending and applying and the like—they confuse the necessities of geometry with those of daily life; whereas knowledge is the real object of the whole science. Certainly, he said. Then must not a further admission be made? What admission? That the knowledge at which geometry aims is knowledge of the eternal, and not of aught perishing and transient. That, he replied, may be readily allowed, and is true. Then, my noble friend, geometry will draw the soul towards truth, and create the spirit of philosophy, and raise up that which is now unhappily allowed to fall down. Nothing will be more likely to have such an effect. Then nothing should be more sternly laid down than that the inhabitants of your fair city should by all means learn geometry. Moreover the science has indirect effects, which are not small. Of what kind? he said. There are the military advantages of which you spoke, I said; and in all departments of knowledge, as experience proves, any one who has studied geometry is infinitely quicker of apprehension than one who has not. Yes indeed, he said, there is an infinite difference between them. Then shall we propose this as a second branch of knowledge which our youth will study? Let us do so, he replied.

(526) And indeed, you will not easily find a more difficult study, and not many as difficult. You will not. And, for all these reasons, arithmetic is a kind of knowledge in which the best natures should be trained, and which must not be given up. I agree. Let this then be made one of our subjects of education. And next, shall we enquire whether the kindred science also concerns us? You mean geometry? Exactly so. Clearly, he said, we are concerned with that part of geometry which relates to war; for in pitching a camp, or taking up a position, or closing or extending the lines of an army, or any other military manoeuvre, whether in actual battle or on a march, it will make all the difference whether a general is or is not a geometrician. Yes, I said, but for that purpose a very little of either geometry or calculation will be enough; the question relates rather to the greater and more advanced part of geometry— whether that tends in any degree to make more easy the vision of the idea of good; and thither, as I was saying, all things tend which compel the soul to turn her gaze towards that place, where is the full perfection of being, which she ought, by all means, to behold. True, he said. Then if geometry compels us to view being, it concerns us; if becoming only, it does not concern us?

(527) And suppose we make astronomy the third—what do you say? I am strongly inclined to it, he said; the observation of the seasons and of months and years is as essential to the general as it is to the farmer or sailor. I am amused, I said, at your fear of the world, which makes you guard against the appearance of insisting upon useless studies; and I quite admit the difficulty of believing that in every man there is an eye of the soul which, when by other pursuits lost and dimmed, is by these purified and re-illumined; and is more precious far than ten thousand bodily eyes, for by it alone is truth seen. Now there are two classes of persons: one class of those who will agree with you and will take your words as a revelation; another class to whom they will be utterly unmeaning, and who will naturally deem them to be idle tales, for they see no sort of profit which is to be obtained from them. And therefore you had better decide at once with which of the two you are proposing to argue. You will very likely say with neither, and that your chief aim in carrying on the argument is your own improvement; at the same time you do not grudge to others any benefit which they may receive. I think that I should prefer to carry on the argument mainly on my own behalf. Then take a step backward, for we have gone wrong in the order of the sciences. What was the mistake? he said. After plane geometry, I said, we proceeded at once to

(9) Ruling, then, over himself and what belongs to him, and possessing a sure grasp, of divine science, he makes a genuine approach to the truth. For the knowledge and apprehension of intellectual objects must necessarily be called certain scientific knowledge, whose function in reference to divine things is to consider what is the First Cause, and what that "by whom all things were made, and without whom nothing was made; " and what things, on the other hand, are as pervasive, and what is comprehensive; what conjoined, what disjoined; and what is the position which each one of them holds, and what power and what service each contributes. And again. among human things, what man himself is, and what he has naturally or preternaturally; and how, again, it becomes him to do or to suffer; and what are his virtues and what his vices; and about things good, bad, and indifferent; also about fortitude, and prudence, and self-restraint, and the virtue which is in all respects complete, namely, righteousness.

(37) From the world of physical pursuits the initiates of old called their disciples into the life of the mind and the spirit. Throughout the ages, the Mysteries have stood at the threshold of Reality--that hypothetical spot between noumenon and phenomenon, the Substance and the shadow. The gates of the Mysteries stand ever ajar and those who will may pass through into the spacious domicile of spirit. The world of philosophy lies neither to the right nor to the left, neither above nor below. Like a subtle essence permeating all space and all substance, it is everywhere; it penetrates the innermost and the outermost parts of all being. In every man and woman these two spheres are connected by a gate which leads from the not-self and its concerns to the Self and its realizations. In the mystic this gate is the heart, and through spiritualization of his emotions he contacts that more elevated plane which, once felt and known, becomes the sum of the worth-while. In the philosopher, reason is the gate between the outer and the inner worlds, the illumined mind bridging the chasm between the corporeal and the incorporeal. Thus godhood is born within the one who sees, and from the concerns of men he rises to the concerns of gods.

(534) 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 are to assign these studies, and in what way they are to be assigned, are questions which remain to be considered. Yes, clearly. You remember, I said, how the rulers were chosen before? Certainly, he said. The same natures must still be chosen, and the preference again given to the surest and the bravest, and, if possible, to the fairest; and, having noble and generous tempers, they should also have the natural gifts which will facilitate their education. And what are these? Such gifts as keenness and ready powers of acquisition; for the mind more often faints from the severity of study than from the severity of gymnastics: the toil is more entirely the mind’s own, and is not shared with the body. Very true, he replied.
