This is our first proof. The second is derived from the three kinds of pleasure, which answer to the three elements of the soul—reason, passion, desire; [581]under which last is comprehended avarice as well as sensual appetite, while passion includes ambition, party-feeling, love of reputation. Reason, again, is solely directed to the attainment of truth, and careless of money and reputation. In accordance with the difference of men’s natures, one of these three principles is in the ascendant, and they have their several pleasures corresponding to them. Interrogate now the three natures, and each one will be found praising his own pleasures and depreciating those of others. The money-maker will contrast the vanity of knowledge with the solid advantages of wealth. The ambitious man will despise knowledge which brings no honour; whereas the philosopher will regard only the fruition of truth, and will call other pleasures necessary rather than good. [582]Now, how shall we decide between them? Is there any better criterion than experience and knowledge? And which of the three has the truest knowledge and the widest experience? The experience of youth makes the philosopher acquainted with the two kinds of desire, but the avaricious and the ambitious man never taste the pleasures of truth and wisdom. Honour he has equally with them; they are ‘judged of him,’ but he is ‘not judged of them,’ for they never attain to the knowledge of true being. And his instrument is reason, whereas their standard is only wealth and honour; and if by reason we are to judge, his good will be the truest. And so we arrive at the result that the pleasure of the rational part of the soul, and a life passed in such pleasure is the pleasantest. [583]He who has a right to judge judges thus. Next comes the life of ambition, and, in the third place, that of money-making.

cxl Twice has the just man overthrown the unjust—once more, as in an Olympian contest, first offering up a prayer to the saviour Zeus, let him try a fall. A wise man whispers to me that the pleasures of the wise are true and pure; all others are a shadow only. Let us examine this: Is not pleasure opposed to pain, and is there not a mean state which is neither? When a man is sick, nothing is more pleasant to him than health. But this he never found out while he was well. In pain he desires only to cease from pain; on the other hand, when he is in an ecstasy of pleasure, rest is painful to him. Thus rest or cessation is both pleasure and pain. But can that which is neither become both? Again, pleasure and pain are motions, and the absence of them is rest; [584]but if so, how can the absence of either of them be the other? Thus we are led to infer that the contradiction is an appearance only, and witchery of the senses. And these are not the only pleasures, for there are others which have no preceding pains. Pure pleasure then is not the absence of pain, nor pure pain the absence of pleasure; although most of the pleasures which reach the mind through the body are reliefs of pain, and have not only their reactions when they depart, but their anticipations before they come. They can be best described in a simile. There is in nature an upper, lower, and middle region, and he who passes from the lower to the middle imagines that he is going up and is already in the upper world; and if he were taken back again would think, and truly think, that he was descending. All this arises out of his ignorance of the true upper, middle, and lower regions. And a like confusion happens with pleasure and pain, and with many other things. [585]The man who compares grey with black, calls grey white; and the man who compares absence of pain with pain, calls the absence of pain pleasure. Again, hunger and thirst are inanitions of the body, ignorance and folly of the soul; and food is the satisfaction of the one, knowledge of the other. Now which is the purer satisfaction—that of eating and drinking, or that of knowledge? Consider the matter thus: The satisfaction of that which has more existence is truer than of that which has less. The invariable and immortal has a more real existence than the variable and mortal, and has a corresponding measure of knowledge and truth. The soul, again, has more existence and truth and knowledge than the body, and is therefore more really satisfied and has a more cxli natural pleasure. [586]Those who feast only on earthly food, are always going at random up to the middle and down again; but they never pass into the true upper world, or have a taste of true pleasure. They are like fatted beasts, full of gluttony and sensuality, and ready to kill one another by reason of their insatiable lust; for they are not filled with true being, and their vessel is leaky (cp. Gorgias, 243 A, foll.). Their pleasures are mere shadows of pleasure, mixed with pain, coloured and intensified by contrast, and therefore intensely desired; and men go fighting about them, as Stesichorus says that the Greeks fought about the shadow of Helen at Troy, because they know not the truth.

The same may be said of the passionate element:—the desires of the ambitious soul, as well as of the covetous, have an inferior satisfaction. Only when under the guidance of reason do either of the other principles do their own business [587]or attain the pleasure which is natural to them. When not attaining, they compel the other parts of the soul to pursue a shadow of pleasure which is not theirs. And the more distant they are from philosophy and reason, the more distant they will be from law and order, and the more illusive will be their pleasures. The desires of love and tyranny are the farthest from law, and those of the king are nearest to it. There is one genuine pleasure, and two spurious ones: the tyrant goes beyond even the latter; he has run away altogether from law and reason. Nor can the measure of his inferiority be told, except in a figure. The tyrant is the third removed from the oligarch, and has therefore, not a shadow of his pleasure, but the shadow of a shadow only. The oligarch, again, is thrice removed from the king, and thus we get the formula 3 × 3, which is the number of a surface, representing the shadow which is the tyrant’s pleasure, and if you like to cube this ‘number of the beast,’ you will find that the measure of the difference amounts to 729; the king is 729 times more happy than the tyrant. And this extraordinary number is nearly equal to the number of days and nights in a year (365 × 2 = 730); and is therefore concerned with human life. [588]This is the interval between a good and bad man in happiness only: what must be the difference between them in comeliness of life and virtue!

Perhaps you may remember some one saying at the beginning of our discussion that the unjust man was profited if he had the cxlii reputation of justice. Now that we know the nature of justice and injustice, let us make an image of the soul, which will personify his words. First of all, fashion a multitudinous beast, having a ring of heads of all manner of animals, tame and wild, and able to produce and change them at pleasure. Suppose now another form of a lion, and another of a man; the second smaller than the first, the third than the second; join them together and cover them with a human skin, in which they are completely concealed. When this has been done, let us tell the supporter of injustice [589]that he is feeding up the beasts and starving the man. The maintainer of justice, on the other hand, is trying to strengthen the man; he is nourishing the gentle principle within him, and making an alliance with the lion heart, in order that he may be able to keep down the many-headed hydra, and bring all into unity with each other and with themselves. Thus in every point of view, whether in relation to pleasure, honour, or advantage, the just man is right, and the unjust wrong.

But now, let us reason with the unjust, who is not intentionally in error. Is not the noble that which subjects the beast to the man, or rather to the God in man; the ignoble, that which subjects the man to the beast? And if so, who would receive gold on condition that he was to degrade the noblest part of himself under the worst?—who would sell his son or daughter into the hands of brutal and evil men, for any amount of money? And will he sell his own fairer and diviner part without any compunction to the most godless and foul? [590]Would he not be worse than Eriphyle, who sold her husband’s life for a necklace? And intemperance is the letting loose of the multiform monster, and pride and sullenness are the growth and increase of the lion and serpent element, while luxury and effeminacy are caused by a too great relaxation of spirit. Flattery and meanness again arise when the spirited element is subjected to avarice, and the lion is habituated to become a monkey. The real disgrace of handicraft arts is, that those who are engaged in them have to flatter, instead of mastering their desires; therefore we say that they should be placed under the control of the better principle in another because they have none in themselves; not, as Thrasymachus imagined, to the injury of the subjects, but for cxliii their good. And our intention in educating the young, is to give them self-control; [591]the law desires to nurse up in them a higher principle, and when they have acquired this, they may go their ways.

‘What, then, shall a man profit, if he gain the whole world’ and become more and more wicked? Or what shall he profit by escaping discovery, if the concealment of evil prevents the cure? If he had been punished, the brute within him would have been silenced, and the gentler element liberated; and he would have united temperance, justice, and wisdom in his soul—a union better far than any combination of bodily gifts. The man of understanding will honour knowledge above all; in the next place he will keep under his body, not only for the sake of health and strength, but in order to attain the most perfect harmony of body and soul. In the acquisition of riches, too, he will aim at order and harmony; he will not desire to heap up wealth without measure, but he will fear that the increase of wealth will disturb the constitution of his own soul. For the same reason [592]he will only accept such honours as will make him a better man; any others he will decline. ‘In that case,’ said he, ‘he will never be a politician.’ Yes, but he will, in his own city; though probably not in his native country, unless by some divine accident. ‘You mean that he will be a citizen of the ideal city, which has no place upon earth.’ But in heaven, I replied, there is a pattern of such a city, and he who wishes may order his life after that image. Whether such a state is or ever will be matters not; he will act according to that pattern and no other….

Republic IX.
INTRODUCTION. The most noticeable points in the 9th Book of the Republic are:—(1) the account of pleasure; (2) the number of the interval which divides the king from the tyrant; (3) the pattern which is in heaven.

1. Plato’s account of pleasure is remarkable for moderation, and in this respect contrasts with the later Platonists and the views which are attributed to them by Aristotle. He is not, like the Cynics, opposed to all pleasure, but rather desires that the several parts of the soul shall have their natural satisfaction; he even agrees with the Epicureans in describing pleasure cxliv as something more than the absence of pain. This is proved by the circumstance that there are pleasures which have no antecedent pains (as he also remarks in the Philebus), such as the pleasures of smell, and also the pleasures of hope and anticipation. In the previous book (pp. [558], [559]) he had made the distinction between necessary and unnecessary pleasure, which is repeated by Aristotle, and he now observes that there are a further class of ‘wild beast’ pleasures, corresponding to Aristotle’s θηριότης. He dwells upon the relative and unreal character of sensual pleasures and the illusion which arises out of the contrast of pleasure and pain, pointing out the superiority of the pleasures of reason, which are at rest, over the fleeting pleasures of sense and emotion. The pre-eminence of royal pleasure is shown by the fact that reason is able to form a judgment of the lower pleasures, while the two lower parts of the soul are incapable of judging the pleasures of reason. Thus, in his treatment of pleasure, as in many other subjects, the philosophy of Plato is ‘sawn up into quantities’ by Aristotle; the analysis which was originally made by him became in the next generation the foundation of further technical distinctions. Both in Plato and Aristotle we note the illusion under which the ancients fell of regarding the transience of pleasure as a proof of its unreality, and of confounding the permanence of the intellectual pleasures with the unchangeableness of the knowledge from which they are derived. Neither do we like to admit that the pleasures of knowledge, though more elevating, are not more lasting than other pleasures, and are almost equally dependent on the accidents of our bodily state (cp. Introduction to Philebus).

2. The number of the interval which separates the king from the tyrant, and royal from tyrannical pleasures, is 729, the cube of 9. Which Plato characteristically designates as a number concerned with human life, because nearly equivalent to the number of days and nights in the year. He is desirous of proclaiming that the interval between them is immeasurable, and invents a formula to give expression to his idea. Those who spoke of justice as a cube, of virtue as an art of measuring (Prot. 357 A), saw no inappropriateness in conceiving the soul under the figure of a line, or the pleasure of the tyrant as separated from the cxlv pleasure of the king by the numerical interval of 729. And in modern times we sometimes use metaphorically what Plato employed as a philosophical formula. ‘It is not easy to estimate the loss of the tyrant, except perhaps in this way,’ says Plato. So we might say, that although the life of a good man is not to be compared to that of a bad man, yet you may measure the difference between them by valuing one minute of the one at an hour of the other (‘One day in thy courts is better than a thousand’), or you might say that ‘there is an infinite difference.’ But this is not so much as saying, in homely phrase, ‘They are a thousand miles asunder.’ And accordingly Plato finds the natural vehicle of his thoughts in a progression of numbers; this arithmetical formula he draws out with the utmost seriousness, and both here and in the number of generation seems to find an additional proof of the truth of his speculation in forming the number into a geometrical figure; just as persons in our own day are apt to fancy that a statement is verified when it has been only thrown into an abstract form. In speaking of the number 729 as proper to human life, he probably intended to intimate that one year of the tyrannical = 12 hours of the royal life.

The simple observation that the comparison of two similar solids is effected by the comparison of the cubes of their sides, is the mathematical groundwork of this fanciful expression. There is some difficulty in explaining the steps by which the number 729 is obtained; the oligarch is removed in the third degree from the royal and aristocratical, and the tyrant in the third degree from the oligarchical; but we have to arrange the terms as the sides of a square and to count the oligarch twice over, thus reckoning them not as = 5 but as = 9. The square of 9 is passed lightly over as only a step towards the cube.
