C. The atoms have no colour,

Come now, listen to discourse gathered by my joyful labour, lest by chance you should think that these white things, which you perceive shining bright before your eyes are made of white first-beginnings, or that things which are black are born of black seeds; or should believe that things which are steeped in any other colour you will, bear this colour because the bodies of matter are dyed with a colour like it. For the bodies of matter have no colour at all, neither like things nor again unlike them.though the mind can well conceive them. And if by chance it seems to you that the mind cannot project itself into these bodies, you wander far astray. For since those born blind, who have never descried the light of the sun, yet know bodies by touch, never linked with colour for them from the outset of their life, you may know that for our mind too, bodies painted with no tint may become a clear concept.

Again, we ourselves feel that whatever we touch in blind darkness is not dyed with any colour. And since I convince you that this may be, I will now teach you that are .

  1. Colour changes, but the atoms must be unchangeable.

For any colour, whatever it be, changes into any other; but the first-beginnings ought in no wise to do this. For it must needs be that something abides unchangeable, that all things be not utterly brought to naught. For whenever a thing changes and passes out of its own limits, straightway this is the death of that which was before. Therefore take care not to dye with colour the seeds of things, lest you see all things altogether pass away to naught.

  1. If atoms are colourless, their varieties of shape, &c., will account for the different colours of things.Moreover, if the nature of colour has not been granted to the first-beginnings, and yet they are endowed with diverse forms, out of which they beget and vary colours of every kind, forasmuch as it is of great matter with what others all the seeds are bound up, and in what position, and what movements they mutually give and receive, you can most easily at once give account, why those things which were a little while before of black colour, are able of a sudden to become of marble whiteness; as the sea, when mighty winds have stirred its level waters, is turned into white waves of shining marble. For you might say that when the substance of that which we often see black has been mingled up, and the order of its first-beginnings changed and certain things added and taken away,But (a) if they are of the colour of the things they compose, change is impossible, and (b) if they are of all colours, the separate colours would be seen, straightway it comes to pass that it is seen shining and white. But if the level waters of the ocean were made of sky-blue seeds, they could in no wise grow white.

For in whatever way you were to jostle together seeds which are sky-blue, never can they pass into a marble colour. But if the seeds which make up the single unmixed brightness of the sea are dyed with this colour and that, even as often out of different forms and diverse shapes some square thing is made up with a single shape, then it were natural that, as in the square we perceive that there are unlike forms, so we should perceive in the water of the ocean, or in any other single and unmixed brightness, colours far different and diverse one from another.and the whole could not be uniform in colour; Moreover, the unlike shapes do not a whit thwart and hinder the whole from being square in its outline; but the diverse colours in things do check and prevent the whole thing being of a single brightness. Then, further, the reason which leads us on and entices us sometimes to assign colours to the first-beginnings of things,further, this contradicts our reason for thinking atoms might have colour. is gone, since white things are not made of white, nor those which are seen black of black, but of diverse colours. And in very truth much more readily will white things be born and rise up out of no colour than out of black, or any other colour you will which fights with it and thwarts it.

  1. Colour needs light, with which the atoms have no relation.Moreover, since colours cannot be without light nor do the first-beginnings of things come out into the light, you may know how they are not clothed with any colour.

For what colour can there be in blind darkness? Nay even in the light it changes according as it shines brightly, struck with a straight or slanting beam of light; even as the plumage of doves, which is set about their throats and crowns their necks, is seen in the sunshine; for anon it comes to pass that it is red with bright garnet,

  1. The perception of colour is due to a blow on the eye: and for touch it is shape, not colour which matters. sometimes in a certain view it comes to pass that it seems to mingle green emeralds among coral. And the tail of the peacock, when it is bathed in bounteous light, in like manner changes its colours as it moves round; and since these colours are begotten by a certain stroke of light, you may know that we must not think that they could come to be without it. And since the pupil of the eye receives in itself a certain kind of blow, when it is said to perceive white colour, and another again, when it perceives black and the rest, nor does it matter with what colour things you touch may choose to be endowed, but rather with what sort of shape they are fitted, you may know that the first-beginnings have no need of colours, but by their diverse forms produce diverse kinds of touch.

  2. Colour and shape not being connected, if atoms have colour, we should have individuals of different colours in the same species.Moreover, since no fixed nature of colour belongs to fixed shapes, and all conformations of first-beginnings may exist in any hue you will, why on like grounds are not those things which are made out of them steeped with every kind of colour in every kind? For it were natural that often flying crows too should throw off white colour from white wings, and that black swans should be made of black seeds or of any other colour you will, simple or diverse.

Nay again, the more each thing is pulled asunder into tiny parts, the more can you perceive colour little by little fading away and being quenched:6. The smaller a body, the less colour it has. as comes to pass when purple is plucked apart into small pieces: when it has been unravelled thread by thread, the dark purple or the scarlet, by far the brightest of colours, is utterly destroyed; so that you can know from this that the tiny shreds dissipate all their colour before they are sundered into the seeds of things.

  1. Just as some things have not smell or sound, so the atoms are without colourLastly, since you do not allow that all bodies send out sound or smell, it comes to pass, therefore, that you do not assign sound and smell to them. Even so, since we cannot with the eyes descry all things, you may know that some things are made bereft of colour, just as some are without any smell and far parted from sound, yet that the keen mind can come to know them no less than it can mark those devoid of other things.

The atoms are also without heat, sound, taste or smell,But lest by chance you think that the first-bodies abide bereft only of colour, they are also sundered altogether from warmth and cold, and fiery heat, and are carried along barren of sound and devoid of taste, nor do they give off any scent of their own from their body. Even as when you set about to make the delicious liquid of marjoram or myrrh, or scent of nard, which breathes nectar to the nostrils, first of all it is right to seek, in so far as you may and can find it, the nature of scentless oil, which may send off no breath of perfume to the nostrils, so that it may as little as possible taint and ruin with its own strong smell the scents mingled in its body and boiled along with it.for they cannot emit anything from their body. Therefore after all the first-beginnings of things are bound not to bring to the begetting of things their own scent or sound, since they cannot give anything off from themselves, nor in the same way acquire any taste at all, nor cold, nor once more warm and fiery heat … and the rest: 1 yet since they are such as to be created mortal, the pliant of soft body, the brittle of crumbling body, the hollow of rare, they must needs all be kept apart from the first-beginnings, if we wish to place immortal foundations beneath things, on which the sum of life may rest; lest you see all things pass away utterly into nothing.

Neither have atoms sense.It must needs be n that you should admit that all things which we see have sense are yet made of insensible first-beginnings. The clear facts, which are known for all to see, neither refute this nor fight against it, but rather themselves lead us by the hand and constrain us to believe that, as I say, living things are begotten of insensible things.1. We see the sensible created elsewhere from the senseless. 2. Inanimate food makes animate bodies. Why we may see worms come forth alive from noisome dung, when the soaked earth has gotten muddiness from immeasurable rains; moreover, we may see all things in like manner change themselves. Streams, leaves, and glad pastures change themselves into cattle, cattle change their nature into our bodies, and from our bodies the strength of wild beasts often gains increase, and the bodies of birds strong of wing. And so nature changes all foods into living bodies, and out of food brings to birth all the senses of living things, in no far different way than she unfolds dry logs into flames and turns all things into fires. Do you not then see now that it is of great matter in what order all the first-beginnings of things are placed, and with what others mingled they give and receive motions?

  1. The fact that sensible things do not normally arise from the insensible is no objection.Next then, what is it, that strikes on the very mind, which stirs it and constrains to utter diverse thoughts, that you may not believe that the sensible is begotten of the insensible? We may be sure it is that stones 1 and wood and earth mixed together yet cannot give out vital sense. Herein it will be right to remember this, that I do not say that sensations are begotten at once from all and every of the things which give birth to sensible things, but that it is of great matter,All depends on the size, position, arrangements, and motions of the atoms. first of what size are these bodies, which create the sensible, and with what form they are endowed, then what they are in their motions, arrangements and positions. And none of these things can we perceive in logs and sods; and yet, when they are, as it were, made muddy through the rains, they give birth to little worms, because the bodies of matter stirred by the newcomer from their old arrangements are brought into union in the way in which living things are bound to be begotten.4. Sensible seeds would be soft and therefore mortal. Next, those who think n that the sensible could be created out of sensible bodies which in turn were used to owe their sense to others, , 1 when they make them soft. For all sensation is linked to flesh, sinews and veins, which we see are always soft in nature built up of mortal body.5. If everlasting, they must either (a) feel as a part of the whole, or (b) as an independent whole. But (a) a part does not feel by itself; But still let us grant now that these can abide for ever: still doubtless they must either have n the sense proper to a part, or be thought to be of a sense like to that of whole living things. But it must needs be that the parts cannot have sense by themselves; for all sensation in the limbs depends on us, nor severed from us can the hand nor any part of the body at all keep sensation by itself. It remains that they are made like whole living things. Thus it must needs be that they feel likewise what we feel, so that they may be able to share with us in every place in the vital sensations.(b) (1) they could not be eternal; How then will they be able to be called the first-beginnings of things and to shun the paths of death, since they are living things, and living things are one and the same with mortal things?(2) they would only make a confused mass of sentient beings; (3) if in the body they lose their sense, why give it them? But our previous examples are enough. Yet grant that they can, still by their meeting and union, they will make nothing besides a crowd and mob of living things, even as, as you may know, men, herds of cattle and wild beasts could not beget anything by coming together with one another. But if by chance they lose their own sense, when inside a body, and receive another, what good was it that that should be assigned to them which is taken away? Then, moreover, as we saw before, inasmuch as we perceive the eggs of birds turn into living chicknes, and worms swarm out when mud has seized on the earth owing to immoderate rains, we may know that sensations can be begotten out of that which is not sensation.

  2. Sensation cannot arise from the insensate by change or birth; for both imply union. (a) A body cannot have sensation before the union of its substance.But if by chance any one shall say n that sensation can in any case arise from not-sensation by change of substance or, as it were, by a kind of birth, by which it is thrust out into being, it will be enough to make clear and prove to him that birth cannot come to be, unless when a union has been formed before, nor is anything changed except after union. First of all, no body at all can have sensation before the nature of the living thing is itself begotten, because, we may be sure, its substance is scattered abroad and is kept in the air, in streams, in earth and things sprung from earth, nor has it come together in appropriate way and combined with one another the vital motions, whereby the all-seeing senses are kindled and see to the safety of each living thing.

(b) A blow puts an end to sensation, because it dissolves unions and stops the vital motions.Moreover, a heavier blow than its nature can endure, of a sudden fells any living creature, and hastens to stun all the sensations of its body and mind. For the positions of the first-beginnings are broken up and the vital motions are checked deep within, until the substance, after the shock throughout all the limbs, loosens the vital clusters of the soul from the body, scatters it abroad and drives it out through every pore. For what else are we to think that a blow can do when it meets each thing,Recovery means reunion and motion restarted. but shake it to pieces and break it up? It comes to pass too, that when a blow meets us with less force, the vital motions that remain are often wont to win, yea, to win and to allay the vast disturbances of the blow and summon each part back again into its proper path, and to shake to pieces the movement of death that now, as it were, holds sway in the body, and to kindle the sensations almost lost. For by what other means could living things gather their wits and turn back to life even from the very threshold of death rather than pass on, whither their race is already almost run, and pass away?

  1. Pleasure and pain are caused by the internal movements of atoms: atoms cannot then themselves experience them.Moreover, since there is pain when the bodies of matter, disturbed by some force throughout the living flesh and limbs, tremble each in their abode within, and when they settle back into their place, comforting pleasure comes to pass, you may know that the first-beginnings cannot be assailed by any pain, and can find no pleasure in themselves: inasmuch as they are not made of any bodies of first-beginnings, through whose newness of movement they may be in pain or find any enjoyment of life-giving delight. They are bound then not to be endowed with any sensation.

  2. Reductio ad absurdum. Sensible atoms must themselves laugh and cry and think and dispute.Again, if, in order that all living things may be able to feel, we must after all assign sensation to their first-beginnings, what of those whereof the race of men has its peculiar increment? n You must think that they are shaken with quivering mirth and laugh aloud and sprinkle face and cheeks with the dew of their tears. And they have the wit to say much about the mingling of things, and they go on to ask what are their first-beginnings; inasmuch as, being made like to whole mortal men, they too must needs be built of other particles in their turn, and those again of others, so that you may never dare to make a stop: nay, I will press hard on you, so that, whatsoever you say speaks and laughs and thinks, shall be composed of other particles which do these same things. But if we perceive this to be but raving madness, and a man can laugh, though he has not the increment of laughing atoms, and can think and give reasons with learned lore, though he be not made of seeds thoughtful and eloquent, why should those things, which, as we see, have feeling, any the less be able to exist, mingled of seeds which lack sense in every way?

Summary Earth is the universal mother.And so, we are all sprung from heavenly seed; there is the one father of us all, from whom when live-giving earth, the mother, has taken within her the watery drops of moisture, teeming she brings forth the goodly crops and the glad trees and the race of men; she brings forth too all the tribes of the wild beasts, when she furnishes the food, on which all feed their bodies and pass a pleasant life and propagate their offspring; wherefore rightly has she won the name of mother. Even so, what once sprung from earth, sinks back into the earth, and what was sent down from the coasts of the sky, returns again, and the regions of heaven receive it.Death is not destruction but reformation, and combination produces qualities and sensation. Nor does death so destroy things as to put an end to the bodies of matter, but only scatters their union. Then she joins anew one with others, and brings it to pass that all things thus alter their forms, and change their colours, and receive sensations, and in an instant of time yield them up again, so that you may know that it matters with what others the first-beginnings of things are bound up and in what position and what motions they mutually give and receive, and may not think that what we see floating on the surface of things n or at times coming to birth, and on a sudden passing away, can abide in the possession of eternal first-bodies. Nay, indeed, even in my verses it is of moment with what others and in what order each letter is placed. For the same letters signify sky, sea, earth, rivers, sun, the same too crops, trees, living creatures; if not all, yet by far the greater part, are alike, but it is by position that things sound different. So in things themselves likewise when meetings, motions, order, position, shapes are changed, things too are bound to be changed.
