Certainly not the last, he replied ; for I know of many things-meats, drinks, medicines, and ten thousand other things, which are inexpedient for man, and some which are expedient ; and some which are neither expedient nor inexpedient for man, but only for horses ; and some for oxen only, and some for dogs ; and some for no animals, but only for trees ; and some for the roots of trees and not for their branches, as for example, manure, which is a good thing when laid about the roots of a tree, but utterly destructive if thrown upon the shoots and young branches ; or I may instance olive oil, which is mischievous to all plants, and generally most injurious to the hair of every animal with the exception of man, but beneficial to human hair and to the human body generally ; and even in this application (so various and changeable is the nature of the benefit), that which is the greatest good to the outward parts of a man, is a very great evil to his INWARD parts : and for this reason physicians always forbid their patients the use of oil in their food, except in very small quantities, just enough to extinguish the disagreeable sensation of smell in meats and sauces.

Soc. I believe that what you say may be true about numbers, which must be just what they are, or not be at all ; for example, the number ten at once becomes other than ten if a unit be added or subtracted, and so of any other number : but this does not apply to that which is qualitative or to anything which is represented under an image. I should say rather that the image, if expressing in every point the entire reality, would no longer be an image. Let us suppose the existence of two objects : one of them shall be Cratylus, and the other the image of Cratylus ; and we will suppose, further, that some God makes not only a representation such as a painter would make of your outward form and colour, but also creates an INWARD organization like yours, having the same warmth and softness ; and into this infuses motion, and soul, and mind, such as you have, in a word copies all your qualities, and places them by you in another form ; would you say that this was Cratylus and the image of Cratylus, or that there were two Cratyluses ? CRATYLUS
Soc. Beloved Pan, and all ye other gods who haunt this place, give me beauty in the INWARD soul ; and may the outward and INWARD man be at one. May I reckon the wise to be the wealthy, and may I have such a quantity of gold as a temperate man and he only can bear and carry. — Anything more ? The prayer, I think, is enough for me. PHAEDRUS
Str. There is the purification of living bodies in their INWARD and in their outward parts, of which the former is duly effected by medicine and gymnastic, the latter by the not very dignified art of the bath-man ; and there is the purification of inanimate substances — to this the arts of fulling and of furbishing in general attend in a number of minute particulars, having a variety of names which are thought ridiculous. SOPHIST
And so in the vessel of the head, they first of all put a face in which they inserted organs to minister in all things to the providence of the soul, and they appointed this part, which has authority, to be by nature the part which is in front. And of the organs they first contrived the eyes to give light, and the principle according to which they were inserted was as follows : So much of fire as would not burn, but gave a gentle light, they formed into a substance akin to the light of every-day life ; and the pure fire which is within us and related thereto they made to flow through the eyes in a stream smooth and dense, compressing the whole eye, and especially the centre part, so that it kept out everything of a coarser nature, and allowed to pass only this pure element. When the light of day surrounds the stream of vision, then like falls upon like, and they coalesce, and one body is formed by natural affinity in the line of vision, wherever the light that falls from within meets with an external object. And the whole stream of vision, being similarly affected in virtue of similarity, diffuses the motions of what it touches or what touches it over the whole body, until they reach the soul, causing that perception which we call sight. But when night comes on and the external and kindred fire departs, then the stream of vision is cut off ; for going forth to an unlike element it is changed and extinguished, being no longer of one nature with the surrounding atmosphere which is now deprived of fire : and so the eye no longer sees, and we feel disposed to sleep. For when the eyelids, which the gods invented for the preservation of sight, are closed, they keep in the internal fire ; and the power of the fire diffuses and equalises the INWARD motions ; when they are equalised, there is rest, and when the rest is profound, sleep comes over us scarce disturbed by dreams ; but where the greater motions still remain, of whatever nature and in whatever locality, they engender corresponding visions in dreams, which are remembered by us when we are awake and in the external world. And now there is no longer any difficulty in understanding the creation of images in mirrors and all smooth and bright surfaces. For from the communion of the internal and external fires, and again from the union of them and their numerous transformations when they meet in the mirror, all these appearances of necessity arise, when the fire from the face coalesces with the fire from the eye on the bright and smooth surface. And right appears left and left right, because the visual rays come into contact with the rays emitted by the object in a manner contrary to the usual mode of meeting ; but the right appears right, and the left left, when the position of one of the two concurring lights is reversed ; and this happens when the mirror is concave and its smooth surface repels the right stream of vision to the left side, and the left to the right. Or if the mirror be turned vertically, then the concavity makes the countenance appear to be all upside down, and the lower rays are driven upwards and the upper downwards. TIMAEUS
On my arrival, I thought that first I must put to the test the question whether Dionysios had really been kindled with the fire of philosophy, or whether all the reports which had come to Athens were empty rumours. Now there is a way of putting such things to the test which is not to be despised and is well suited to monarchs, especially to those who have got their heads full of erroneous teaching, which immediately my arrival I found to be very much the case with Dionysios. One should show such men what philosophy is in all its extent ; what their range of studies is by which it is approached, and how much labour it involves. For the man who has heard this, if he has the true philosophic spirit and that godlike temperament which makes him a kin to philosophy and worthy of it, thinks that he has been told of a marvellous road lying before him, that he must forthwith press on with all his strength, and that life is not worth living if he does anything else. After this he uses to the full his own powers and those of his guide in the path, and relaxes not his efforts, till he has either reached the end of the whole course of study or gained such power that he is not incapable of directing his steps without the aid of a guide. This is the spirit and these are the thoughts by which such a man guides his life, carrying out his work, whatever his occupation may be, but throughout it all ever cleaving to philosophy and to such rules of diet in his daily life as will give him INWARD sobriety and therewith quickness in learning, a good memory, and reasoning power ; the kind of life which is opposed to this he consistently hates. Those who have not the true philosophic temper, but a mere surface colouring of opinions penetrating, like sunburn, only skin deep, when they see how great the range of studies is, how much labour is involved in it, and how necessary to the pursuit it is to have an orderly regulation of the daily life, come to the conclusion that the thing is difficult and impossible for them, and are actually incapable of carrying out the course of study ; while some of them persuade themselves that they have sufficiently studied the whole matter and have no need of any further effort. This is the sure test and is the safest one to apply to those who live in luxury and are incapable of continuous effort ; it ensures that such a man shall not throw the blame upon his teacher but on himself, because he cannot bring to the pursuit all the qualities necessary to it. Thus it came about that I said to Dionysios what I did say on that occasion. LETTERS LETTER VII
Now that those who practise justice do so involuntarily and because they have not the power to be unjust will best appear if we imagine something of this kind : having given both to the just and the unjust power to do what they will, let us watch and see whither desire will lead them ; then we shall discover in the very act the just and unjust man to be proceeding along the same road, following their interest, which all natures deem to be their good, and are only diverted into the path of justice by the force of law. The liberty which we are supposing may be most completely given to them in the form of such a power as is said to have been possessed by Gyges, the ancestor of Croesus the Lydian. According to the tradition, Gyges was a shepherd in the service of the King of Lydia ; there was a great storm, and an earthquake made an opening in the earth at the place where he was feeding his flock. Amazed at the sight, he descended into the opening, where, among other marvels, he beheld a hollow brazen horse, having doors, at which he, stooping and looking in, saw a dead body of stature, as appeared to him, more than human and having nothing on but a gold ring ; this he took from the finger of the dead and reascended. Now the shepherds met together, according to custom, that they might send their monthly report about the flocks to the King ; into their assembly he came having the ring on his finger, and as he was sitting among them he chanced to turn the collet of the ring inside his hand, when instantly he became invisible to the rest of the company and they began to speak of him as if he were no longer present. He was astonished at this, and again touching the ring he turned the collet outward and reappeared ; he made several trials of the ring, and always with the same result — when he turned the collet INWARD he became invisible, when outward he reappeared. Whereupon he contrived to be chosen one of the messengers who were sent to the court ; where as soon as he arrived he seduced the Queen, and with her help conspired against the King and slew him and took the kingdom. Suppose now that there were two such magic rings, and the just put on one of them and the unjust the other ; no man can be imagined to be of such an iron nature that he would stand fast in justice. No man would keep his hands off what was not his own when he could safely take what he liked out of the market, or go into houses and lie with anyone at his pleasure, or kill or release from prison whom he would, and in all respects be like a god among men. Then the actions of the just would be as the actions of the unjust ; they would both come at last to the same point. And this we may truly affirm to be a great proof that a man is just, not willingly or because he thinks that justice is any good to him individually, but of necessity, for wherever anyone thinks that he can safely be unjust, there he is unjust. For all men believe in their hearts that injustice is far more profitable to the individual than justice, and he who argues as I have been supposing, will say that they are right. If you could imagine anyone obtaining this power of becoming invisible, and never doing any wrong or touching what was another’s, he would be thought by the lookers-on to be a most wretched idiot, although they would praise him to one another’s faces, and keep up appearances with one another from a fear that they too might suffer injustice. Enough of this. THE REPUBLIC BOOK II
And therefore, I said, Glaucon, musical training is a more potent instrument than any other, because rhythm and harmony find their way into the INWARD places of the soul, on which they mightily fasten, imparting grace, and making the soul of him who is rightly educated graceful, or of him who is ill-educated ungraceful ; and also because he who has received this true education of the inner being will most shrewdly perceive omissions or faults in art and nature, and with a true taste, while he praises and rejoices over and receives into his soul the good, and becomes noble and good, he will justly blame and hate the bad, now in the days of his youth, even before he is able to know the reason why ; and when reason comes he will recognize and salute the friend with whom his education has made him long familiar. THE REPUBLIC BOOK III
But in reality justice was such as we were describing, being concerned, however, not with the outward man, but with the INWARD, which is the true self and concernment of man : for the just man does not permit the several elements within him to interfere with one another, or any of them to do the work of others — he sets in order his own inner life, and is his own master and his own law, and at peace with himself ; and when he has bound together the three principles within him, which may be compared to the higher, lower, and middle notes of the scale, and the intermediate intervals — when he has bound all these together, and is no longer many, but has become one entirely temperate and perfectly adjusted nature, then he proceeds to act, if he has to act, whether in a matter of property, or in the treatment of the body, or in some affair of politics or private business ; always thinking and calling that which preserves and co-operates with this harmonious condition just and good action, and the knowledge which presides over it wisdom, and that which at any time impairs this condition he will call unjust action, and the opinion which presides over it ignorance.
