The limbs and senses were not created for the purpose of their use,Herein you must eagerly desire to shun this fault, and with foresighted fear to avoid this error; do not think that the bright light of the eyes was created in order that we may be able to look before us, or that, in order that we may have power to plant long paces, therefore the tops of shanks and thighs, based upon the feet, are able to bend; or again, that the forearms are jointed to the strong upper arms and hands given us to serve us on either side, in order that we might be able to do what was needful for life.
All other ideas of this sort, which men proclaim, by distorted reasoning set effect for cause, since nothing at all was born in the body that we might be able to use it, but what is born creates its own use.but being created evolved their use. Nor did sight exist before the light of the eyes was born, nor pleading in words before the tongue was created, but rather the birth of the tongue came long before discourse, and the ears were created much before sound was heard, and in short all the limbs, I trow, existed before their use came about: they cannot then have grown for the purpose of using them.Art may create things for a purpose, But, on the other side, to join hands in the strife of battle, to mangle limbs and befoul the body with gore; these things were known long before gleaming darts flew abroad, and nature constrained men to avoid a wounding blow, before the left arm, trained by art, held up the defence of a shield. And of a surety to trust the tired body to rest was a habit far older than the soft-spread bed, and the slaking of the thirst was born before cups. These things, then, which are invented to suit the needs of life, might well be thought to have been discovered for the purpose of using them.but nature has no design. But all those other things lie apart, which were first born themselves, and thereafter revealed the concept of their usefulness. In this class first of all we see the senses and the limbs; wherefore, again and again, it cannot be that you should believe that they could have been created for the purpose of useful service.
The desire for food is caused by the waste of the body’s tissue, which food in turn repairs.This, likewise, is no cause for wonder, that the nature of the body of every living thing of itself seeks food. For verily I have shown n that many bodies ebb and pass away from things in many ways, but most are bound to pass from living creatures. For because they are sorely tried by motion and many bodies by sweating are squeezed and pass out from deep beneath, many are breathed out through their mouths, when they pant in weariness; by these means then the body grows rare, and all the nature is undermined; and on this follows pain. Therefore food is taken to support the limbs and renew strength when it passes within, and to muzzle the gaping desire for eating through all the limbs and veins.Drink quenches the excessive dryness and heat in the body. Likewise, moisture spreads into all the spots which demand moisture; and the many gathered bodies of heat, which furnish the fires to our stomach, are scattered by the incoming moisture, and quenched like a flame, that the dry heat may no longer be able to burn our body. Thus then the panting thirst is washed away from our body, thus the hungry yearning is satisfied.
Causes of our movements.Next, how it comes to pass that we are able to plant our steps forward, when we wish, how it is granted us to move our limbs in diverse ways, and what force is wont to thrust forward this great bulk of our body, I will tell: do you hearken to my words.1. The image of ourselves moving is presented to the mind: then follows an act of will. The mind then stirs the soul-atoms. I say that first of all idols of walking fall upon our mind, and strike the mind, as we have said before. Then comes the will; for indeed no one begins to do anything, ere the mind has seen beforehand what it will do, and inasmuch as it sees this beforehand, an image of the thing is formed. And so, when the mind stirs itself so that it wishes to start and step forward, it straightway strikes the force of soul which is spread abroad in the whole body throughout limbs and frame. And that is easy to do, since it is held in union with it. Then the soul goes on and strikes the body,and the soul-atoms those of body. 2. Exercise rarefies the body, and its spaces are filled with air, which helps in motion. and so little by little the whole mass is thrust forward and set in movement. Moreover, at such times the body too becomes rarefied, and air (as indeed it needs must do, since it is always quick to move), comes through the opened spaces, and pierces through the passages in abundance, and so it is scattered to all the tiny parts of the body. Here then it is brought about by two causes acting severally, that the body, like a ship, is borne on by sails and wind. n Nor yet herein is this cause for wonder,There are parallels for the moving of a great mass by tiny causes: e. g. a ship in a wind or a crane. that such tiny bodies can twist about a body so great, and turn round the whole mass of us. For in very truth the wind that is finely wrought of a subtle body drives and pushes on a great ship of great bulk, and a single hand steers it, with whatever speed it be moving, and twists a single helm whithersoever it will; and by means of pulleys and tread-wheels a crane can move many things of great weight, and lift them up with light poise.
The cause of sleep.Now in what ways this sleep floods repose over the limbs, and lets loose the cares of the mind from the breast, I will proclaim in verses of sweet discourse, rather than in many; even as the brief song of the swan is better than the clamour of cranes, which spreads abroad among the clouds of the south high in heaven. Do you lend me a fine ear and an eager mind, lest you should deny that what I say can be, and with a breast that utterly rejects the words of truth part company with me, when you are yourself in error and cannot discern.It comes when the soul is scattered in the limbs, or driven out, or hidden deep within. For sense is due to the soul: and its cessation shows that the soul has gone: but not utterly, for that would mean death. First of all sleep comes to pass n when the strength of the soul is scattered about among the limbs, and in part has been cast out abroad and gone its way, and in part has been pushed back and passed inward deeper within the body. For then indeed the limbs are loosened and droop. For there is no doubt that this sense exists in us, thanks to the soul; and when sleep hinders it from being, then we must suppose that the soul is disturbed and cast out abroad: yet not all of it; for then the body would lie bathed in the eternal chill of death. For indeed, when no part of the soul stayed behind hidden in the limbs, as fire is hidden when choked beneath much ashes, whence could sense on a sudden be kindled again throughout the limbs, as flame can rise again from a secret fire?
This is brought about because the body is constantly buffeted by air outsideBut by what means this new state of things is brought about, and whence the soul can be disturbed and the body grow slack, I will unfold: be it your care that I do not scatter my words to the winds. First of all it must needs be that the body on the outer side, since it is touched close at hand by the breezes of air, is thumped and buffeted by its oft-repeated blows, and for this cause it is that wellnigh all things are covered either by a hide,and inside, as we breathe. or else by shells, or by a hard skin, or by bark. Further, as creatures breathe, the air at the same time smites on the inner side, when it is drawn in and breathed out again. Wherefore,The blows spread and cause disruption; since the body is buffeted on both sides alike, and since the blows pass on through the tiny pores to the first parts and first particles of our body, little by little there comes to be, as it were, a falling asunder throughout our limbs. For the positions of the first-beginnings of body and mind are disordered.and so the soul is driven out or sinks within or is distracted, Then it comes to pass that a portion of the soul is cast out abroad, and part retreats and hides within; part too, torn asunder through the limbs, cannot be united in itself, nor by motion act and react; for nature bars its meetings and chokes the ways; and so, when the motions are changed, sense withdraws deep within.and the unsupported body sinks in slackness. And since there is nothing which can, as it were, support the limbs, the body grows feeble, and all the limbs are slackened; arms and eyelids droop, and the hams, even as you lie down, often give way, and relax their strength. Again,Food acts in just the same way as air. sleep follows after food, because food brings about just what air does, while it is being spread into all the veins, and the slumber which you take when full or weary, is much heavier because then more bodies than ever are disordered, bruised with the great effort. In the same manner the soul comes to be in part thrust deeper within; it is also more abundantly driven out abroad, and is more divided and torn asunder in itself within.
Dreams repeat the actions which we pursue in waking life.And for the most part to whatever pursuit each man clings and cleaves, or on whatever things we have before spent much time, so that the mind was more strained in the task than is its wont, in our sleep we seem mostly to traffic in the same things; lawyers think that they plead their cases and confront law with law, generals that they fight and engage in battles, sailors that they pass a life of conflict waged with winds, and we that we pursue our task and seek for the nature of things for ever, and set it forth, when it is found, in writings in our country’s tongue. Thus for the most part all other pursuits and arts seem to hold the minds of men in delusion during their sleep.For instance, the games. And if ever men have for many days in succession given interest unflagging to the games, we see for the most part, that even when they have ceased to apprehend them with their senses, yet there remain open passages in their minds, whereby the same images of things may enter in. And so for many days the same sights pass before their eyes, so that even wide awake they think they see men dancing and moving their supple limbs, and drink in with their ears the clear-toned chant of the lyre, and its speaking strings,This is true even of animals: and behold the same assembly and at the same time the diverse glories of the stage all bright before them. So exceeding great is the import of zeal and pleasure, and the tasks wherein not only men are wont to spend their efforts, but even every living animal. In truth you will see strong horses,horses, when their limbs are lain to rest, yet sweat in their sleep, and pant for ever, and strain every nerve as though for victory, or else as though the barriers were opened
The nature of love and desire.There is stirred in us that seed, whereof we spoke before, when first the age of manhood strengthens our limbs. For one cause moves and rouses one thing, a different cause another; from man only the influence of man stirs human seed. And as soon as it has been aroused, bursting forth it makes its way from out the whole body through the limbs and frame, coming together into fixed places, and straightway rouses at last the natural parts of the body;It makes us seek union with the object by which we are smitten. and there arises the desire to seek that body, by which the mind is smitten with love. For as a rule all men fall towards the wound, and the blood spirts out in that direction, whence we are struck by the blow, and, if it is near at hand, the red stream reaches our foe. Thus, then, he who receives a blow from the darts of Venus, whoso’er it be who wounds him, inclines to that whereby he is smitten; for an unspoken desire foretells the pleasure to come.
