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; 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 moneymaker 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. 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. He who has a right to judge judges thus. Next comes the life of ambition, and, in the third place, that of moneymaking.
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; 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. 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 natural pleasure. 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
