Why choose fire as the primal substancec?

Besides, why should any one rather annul all things, and wish to leave only the nature of heat, than deny that fire exists, and grant in its stead that another nature exists?

For it seems equal madness to say the one or the other.

That (a) other elements are the primal substance,Wherefore those who have thought that fire is the substance of things, and that the whole sum may be built of fire, and those who have set up air as the first-beginning for the begetting of things, or again all who have thought that moisture fashions things alone by itself, or that earth creates all and passes into all the natures of things, seem to have strayed very far away from the truth.or

(b)a combination of two, or

(c) of four.

Add to them too those who make the first-beginnings of things twofold, linking air to fire or earth to water, and those who think that all can grow up out of four things, fire, earth, wind, and rain.

Of them in the forefront comes Empedocles of Acragas.

him that island bore within the three-cornered coasts of its lands, around which flows the Ionian ocean, with many a winding inlet,Empedocles. splashing salt foam from its green waves, while with narrow strait a tearing sea sunders with its waves the coasts of Italy’s lands from the island-borders.

Here is devastating Charybdis, and here the rumblings of Aetna threaten to gather once more the flames of its wrath, that again in its might it may belch forth the fires bursting from its throat, and once more dash to the sky its flashing flames. And though this mighty country seems in many ways marvellous to the tribes of men, and is said to deserve seeing, rich in goodly things, and strengthened with a mighty wealth of men, yet it is seen to have held nothing in it more glorious than this man, nothing more holy, more marvellous and loved. Nay, the songs of his godlike heart lift up their voice and set forth his glorious discoveries, so that he seems scarce born of human stock.

Errors of Empedocles and his school:

Yet he and those whom I named before, weaker than he by exceeding many degrees, and far beneath him, though they discovered much in good, nay godlike fashion, and gave answers as from the shrine of their hearts in more holy wise and with reasoning far more sure than the Pythian priestess who speaks out from the tripod and laurel of Phoebus, yet in the first-beginnings of things they came to grief: great were they, and great and heavy their fall therein.1. they deny the void:

First because they take away the void from things, but suppose movement, and leave things soft and rare, air, sunlight, fire, earth, beasts, and crops, and yet mingle no void in their body.

  1. they set no limit to division;

Then because they hold that there is no limit at all to the cutting of bodies, that no halting-place is set to their breaking, nor again is there any least among things. And that when we see that there is that extreme point in each thing, which is seen to be the least to our senses, so that you can infer from this that the extreme point in things which you cannot see is the least in them. Then follows this that,3. their elements are soft since they suppose the first-beginnings of things soft, things which we see come to birth and endowed throughout with a mortal body, the whole sum of things must then return to naught, and the store of things be born again, and grow strong out of nothing.

How far both this and that are from the truth, you will know by now.4. and pernicious to one another. Then again, these things are in many ways hostile, nay poison, the one to the other; therefore either when they meet they will pass away, or they will so fly apart, as when a storm gathers we see the thunderbolts and rain and wind fly asunder.

  1. Why not call things the primal substance of the elements?Again, if from four things all are created and all again are dissolved into those things, how can they be called the first-beginnings of things any more than things the first-beginnings of them, with our thought reversed? For they are begotten turn by turn, and change their colour and all their nature one with the other from all time onward. But if perchance you think that the body of fire and the body of earth and the breezes of the air and the dewy moisture so unite,6. or, if the elements do not change in compounds, what else could they create? that in union no one of them changes its nature, you will see that nothing can be created out of them, no, not a living thing, nor one with lifeless body, like a tree. Indeed in the mingling of this diverse mass each thing will reveal its own nature, and air will be seen to be mixed together with earth, and heat to cleave to moisture. But first-beginnings ought in the begetting of things to bring to bear a secret and unseen nature, that nothing may stand out which might bar and thwart whatever is created from existing with its own true being.

  2. The flux of the elements destroys permanence;But indeed they trace it back to heaven and heaven’s fires, and hold that fire first turns itself into the breezes of the sky, that thence is begotten rain, and of rain is created earth, and then all things pass back again from earth, first moisture, next air, then heat, and that these things never cease their mutual changes, in their path from heaven to earth, from earth to the stars of the firmament. 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 altogether 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. Wherefore since the things we have named a little before pass into a state of interchange, they must needs be made of other things, which cannot in any case be altered, lest you find all things returning altogether to naught. Why not rather suppose that there are certain bodies endowed with such a nature, and that, if by chance they have created fire, they can too, when a few are removed and a few added, and their order and movement is changed, make the breezes of the sky, and that thus all things are changed one into another?

  3. the argument from the presence of the four elements in growth;‘But,’ you say, ‘the facts show clearly that all things are nourished and grow from the earth up into the breezes of the sky; and unless the season at a propitious time fosters them with rain, so that the trees rock beneath the outpouring of the storm-clouds, and the sun for its part cherishes them, and bestows its heat on them, crops, trees, living creatures, none could grow.’ Yes, in very truth, unless we too were nurtured by dry food and soft moisture, we should lose our flesh, and all the life too would be loosened from all our sinews and bones.its true atomic explanation. For beyond all doubt we are nurtured and nourished upon things determined, and other things again, each in their turn, on things determined. Yea, we may be sure, it is because many first-beginnings common in many ways to many things are mingled among things, that so diverse things are nourished on diverse food. And often it is of great matter with what others those first-beginnings are bound up, and in what position, and what movements they mutually give and receive; for the same build up sky, sea, earth, rivers, sun, the same too crops, trees, living creatures, but only when mingled with different things and moving in different ways. Indeed scattered abroad in my verses you see many letters common to many words, and yet you must needs grant that verses and words are unlike both in sense and in the ring of their sound. So great is the power of letters by a mere change of order. But the first-beginnings of things can bring more means to bear, by which all diverse things may be created.

The homoeomeria of Anaxagoras:Now let us also search into the homoeomeria of Anaxagoras, n as the Greeks term it, though the poverty of our country’s speech does not suffer us to name it in our own tongue; nevertheless the thing itself it is easy to set forth in words. First—what he calls the homoeomeria of things—you must know that he thinks that bones are made of very small and tiny bones, and flesh of small and tiny pieces of flesh, and blood is created of many drops of blood coming together in union, and that gold again can be built up of grains of gold, and the earth grow together out of little earths, that fire is made of fires, and water of water-drops, and all the rest he pictures and imagines in the same way.

  1. he denies the void; And yet he does not allow that there is void in things on any side, nor that there is a limit to the cutting up of bodies. Therefore in this point and that he seems to me to go astray just as they did

  2. he sets no limit to division; of whom I told above. Add too to this that he pictures his first-beginnings too weak: if indeed those are first-beginnings, which exist endowed with a nature like things themselves, which suffer none the less, and pass away, nor does anything rein them back from their destruction.

  3. his first particles are soft; For which of them all will hold out beneath strong pressure, so as to escape death in the very jaws of destruction? fire or moisture or breeze? which of these? blood or bones? Not one, I trow, when everything alike will be altogether as mortal as the things we see clearly before our eyes vanquished by some violence and passing away. But that things cannot fall away into nothing, nor again grow from nothing, I call to witness what I have before now proved.4. he does not account for change. Moreover, since ’tis food that increases and nourishes the body, you may know that our veins and blood and bones and sinews are created of parts alien in kind

or if they say that all foods are of mingled substance, and have in them little bodies of sinews, and bones and indeed veins and portions of gore, then it will be that all food, both dry, yes and liquid too, must be thought to consist of things alien in kind, of bones and sinews and matter and blood mingled together. Moreover, if all bodies that grow from out the earth are in the earth, the earth must be composed of things alien in kind, which rise up out of the earth. Shift this to another field, you may use the same words again. If in logs flame lurks hidden, and smoke and ash, it must needs be that the logs are composed of things alien in kind. Moreover, all the bodies which the earth nourishes, it increases from things alien in kind, which rise up out of the earth. So too the bodies which logs emit, are nourished

upon things alien in kind, which rise up out of the logs.

Anaxagoras’s evasion: ‘all things are in all things’;Herein there is left a slight chance of hiding from justice, which Anaxagoras grasps for himself, to hold that all things are mingled, though in hiding, in all things, but that that one thing comes out clear, whereof there are most parts mingled in, stationed more ready to view and in the forefront. But this is very far banished from true reasoning. For it were right then that corn also,then they ought to appear. when crushed by the threatening strength of rock, should often give out some sign of blood, or one of those things which are nourished in our body, and that when we rub it with stone on stone, gore should ooze forth. In the same way it were fitting that blades of grass too and pools of water should often give out sweet drops with a savour like the richness of the milk of fleecy beasts, and that often when sods of earth are crumbled, kinds of grasses and corn and leaves should be seen, hiding in tiny form, scattered about among the earth, lastly that ash and smoke should be seen in logs, when they were broken off, and tiny flames in hiding. But since facts clearly show that none of these things comes to pass, you may be sure that things are not so mingled in other things, but that seeds common to many things lie mingled and hidden in things in many ways.

The argument from forest conflagrations.

‘But often on mighty mountains it comes to pass,’ you say, ‘that the neighbouring tops of tall trees rub together, when the strong south winds constrain them to it, until at last a flowery flame gathers, and they blaze with fire.’

Yet you know that fire is not implanted in their wood, but there are many seeds of heat, which when they have flowed together through the rubbing, create fires in the forests. But if the flame had been hidden away ready-made in the forests, the fires could not have been concealed for any time, they would consume the forests one and all, and burn the trees to ashes.

The true atomic explanation.

It is of very great matter often with what others those same first-beginnings are bound up, and in what position, and what movements they mutually give and receive, and that the same a little changed with one another can create bearns or flames? Even as the words themselves have their letters but little changed, when with sound distinct we signify beams or flames.Reductio ad absurdum.

If you think that all that you can descry in things clear to be seen cannot come to being, but that you must suppose first-bodies of matter endowed with a nature like the whole, by this reasoning you see the first-beginnings of things pass away. Nay, it will come to be that they will be shaken with quivering mirth and laugh aloud, and wet face and cheeks with salt tears.
