{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
