(56) Timaeus: and the fractions of air which come from the dissolving of one particle will form two corpuscles of fire. And again, when a small quantity of fire is enclosed by a large quantity of air and water, or of earth, and moves within them as they rush along, and is defeated in its struggle and broken up, then two corpuscles of fire unite to make one form of air. And when air is defeated and disintegrated, from two whole forms of air and a half, one whole form of water will be compounded.

(2) Air is, therefore, twofold in nature-tangible atmosphere and an intangible, volatile substratum which may be termed spiritual air. Fire is visible and invisible, discernible and indiscernible--a spiritual, ethereal flame manifesting through a material, substantial flame. Carrying the analogy further, water consists of a dense fluid and a potential essence of a fluidic nature. Earth has likewise two essential parts--the lower being fixed, terreous, immobile; the higher, rarefied, mobile, and virtual. The general term elements has been applied to the lower, or physical, phases of these four primary principles, and the name elemental essences to their corresponding invisible, spiritual constitutions. Minerals, plants, animals, and men live in a world composed of the gross side of these four elements, and from various combinations of them construct their living organisms.

(20) And if you open the Eyes of your Mind, you will see that Fire is in Water, as may be seen in a Storm of Lightening, and yet it is no durable Fire, though it be true Fire, which sets Houses on Fire, and burns them. So also you may see that there goes forth from it a mighty forcible Air, and that they are in one another; and besides, you see that Water is generated in the Storm.

(61) Timaeus: Thus earth when it is not forcibly condensed is dissolved only by water; and when it is condensed it is dissolved by fire only, since no entrance is left for anything save fire. Water, again, when most forcibly massed together is dissolved by fire only, but when massed less forcibly both by fire and air, the latter acting by way of the interstices, and the former by way of the triangles; but air when forcibly condensed is dissolved by nothing save by way of its elemental triangles, and when unforced it is melted down by fire only. As regards the classes of bodies which are compounds of earth and water,

(59) Timaeus: but because of their outflow it is compressed upon itself; and when it is thus solidified, the part of it above the earth which is most affected by this process is termed “hail,” and the part upon the earth “ice” and the part which is less affected and is still only half-solid is called snow when it is above the earth, but when it is upon the earth and solidified out of dew it is called “hoar-frost.” Now as regards most forms of water that are intermingled one with another, the kind as a whole, consisting of water that has been strained through earth-grown plants,

(2) All these, through growth, or the body which is formed, mingle again with the rivers, for the body which is formed and the growth are both one.

(2) This, however, raises a problem deserving investigation in itself: what has happened when a definite magnitude of water becomes air, and how do we explain the increase of volume? But for the present we must be content with the matter thus far discussed out of all the varied controversy accumulated on either side.

It remains for us to make out on our own account the true explanation of the phenomenon of mixing, without regard to the agreement or disagreement of that theory with any of the current opinions mentioned.

When water runs through wool or when papyrus-pulp gives up its moisture why is not the moist content expressed to the very last drop or even, without question of outflow, how can we possibly think that in a mixture the relation of matter with matter, mass with mass, is contact and that only the qualities are fused? The pulp is not merely in touch with water outside it or even in its pores; it is wet through and through so that every particle of its matter is drenched in that quality. Now if the matter is soaked all through with the quality, then the water is everywhere in the pulp.

"Not the water; the quality of the water."

But then, where is the water? and why is there a change of volume? The pulp has been expanded by the addition: that is to say it has received magnitude from the incoming substance but if it has received the magnitude, magnitude has been added; and a magnitude added has not been absorbed; therefore the combined matter must occupy two several places. And as the two mixing substances communicate quality and receive matter in mutual give and take so they may give and take magnitude. Indeed when a quality meets another quality it suffers some change; it is mixed, and by that admixture it is no longer pure and therefore no longer itself but a blunter thing, whereas magnitude joining magnitude retains its full strength.

But let it be understood how we came to say that body passing through and through another body must produce disintegration, while we make qualities pervade their substances without producing disintegration: the bodilessness of qualities is the reason. Matter, too, is bodiless: it may, then, be supposed that as Matter pervades everything so the bodiless qualities associated with it- as long as they are few- have the power of penetration without disintegration. Anything solid would be stopped either in virtue of the fact that a solid has the precise quality which forbids it to penetrate or in that the mere coexistence of too many qualities in Matter produces the same inhibition.

If, then, what we call a dense body is so by reason of the presence of many qualities, that plenitude of qualities will be the cause .

If on the other hand density is itself a quality like what they call corporeity, then the cause will be that particular quality.

This would mean that the qualities of two substances do not bring about the mixing by merely being qualities but by being apt to mixture; nor does Matter refuse to enter into a mixing as Matter but as being associated with a quality repugnant to mixture; and this all the more since it has no magnitude of its own but only does not reject magnitude.

(1) Second causes only operate in subordination to, and form the impulsion of, the First Cause. Air, earth, water, and fire are God's servants. To us they seem lifeless, but to God living. In God's presence fire ever waits to do its service, When you strike steel on flint fire leaps forth; But 'tis by God's command it thus steps forth. Strike not together the flint and steel of wrong, For the pair will generate more, like man and woman. The flint and steel are themselves causes, yet

(4) Panvotrus saith:—I signify to posterity that air is a tenuous matter of water, and that it is not separated from it. It remains above the dry earth, to wit, the air hidden in the water, which is under the earth. If this air did not exist, the earth would not remain above the humid water. They answer:—Thou hast said well; complete, therefore, thy speech. Sut he continueth: The air which is hidden in the water under the earth is that which sustains the earth, lest it should be plunged into the said water; and it, moreover, prevents the earth from being overflowed by that water. The province of the air is, therefore, to fill up and to make separation between diverse things, that is to say, water and earth, and it is constituted a peacemaker between hostile things, namely, water and fire, dividing these, lest they destroy one another.

The Turba saith:—If you gave an illustration hereof, it would be clearer to those who do not understand.

He answereth:—An egg is an illustration, for therein four things are conjoined; the visible cortex or shell represents the earth, and the albumen, or white part, is the water.* But a very thin inner cortex is joined to the outer cortex, representing, as I have signified to you, the separating medium between earth and water, namely, that air which divides the earth from the water. The yolk also of the egg represents fire; the cortex which contains the yolk corresponds to that other air which separates the water from the fire. But they are both one and the same air, namely, that which separates things frigid, the earth from the water, and that which separates the water from the fire. But the lower air is thicker than the upper air, and the upper air is more rare and subtle, being nearer to the fire than the lower air. In the egg, therefore, are four things—earth, water, air, and fire. But the point of the Sun, these four excepted, is in the centre of the yolk, and this is the chicken. Consequently, all philosophers in this most excellent art have described the egg as an example, which same thing they have set over their work.

(97) 3. The first elements are air, water, and fire; the fire is above, the water is below, and a breath of air establishes balance between them. The token is: the fire carries the water. The letterמ (M) is mute; ש (Sh) is hissing like fire; there is א (A) among them, a breath of air which reconciles the two.

(19) And so every Element qualifies [or acts] in its own Source [or Manner of Operation,] and one could do nothing without the other, neither could one have any Mobility without the other. For one generates the other, and they go all four out of one Original, and it is in its Birth but one only [Thing or] Substance as I have mentioned before at large about the Creation, concerning the Birth of the four Elements.

(2) 'When water dries up, it goes into air. Air indeed consumes them all. So much with reference to the Devas.

(58) Timaeus: So likewise of air, there is the most translucent kind which is called by the name of aether, and the most opaque which is mist and darkness, and other species without a name, which are produced by reason of the inequality of the triangles. The kinds of water are, primarily, two, the one being the liquid, the other the fusible kind. Now the liquid kind, inasmuch as it partakes of those small particles of water which are unequal, is mobile both in itself and by external force owing to its non-uniformity and the shape of its figure. But the other kind, which is composed of large

(44) As an illustration of the fact just stated, we may consider the two opposites known as Hot and Cold, respectively; surely there can be no two qualities apparently more distinct and separate from each other—more diametrically different from each other. But careful examination shows us that the two contrasting things are really but degrees, conditions, and states of the same thing. There is no such thing as an "absolute hot," or an "absolute cold." There are merely different degrees of this Hot-Cold pair of opposites, which for convenience we call "Heat." We cannot point out a place on the thermometer where Hot ceases and Cold begins, or vice versa. The two states or conditions blend into each other, and any statement regarding them is found to be merely comparative. If we place one hand in a bowl of very hot water, and the other in a bowl of ice-cold water, and then suddenly withdraw both hands and plunge them into a bowl of lukewarm water, what happens d Simply this, that we find that the hot-water hand feels a sensation of coolness, while the cold-water hand feels a sensation of heat—each experience resulting from the comparison with the previous experience.

(1) Some enquiry must be made into what is known as the complete transfusion of material substances.

Is it possible that fluid be blended with fluid in such a way that each penetrate the other through and through? or- a difference of no importance if any such penetration occurs- that one of them pass completely through the other?

Those that admit only contact need not detain us. They are dealing with mixture, not with the coalescence which makes the total a thing of like parts, each minutest particle being composed of all the combined elements.

But there are those who, admitting coalescence, confine it to the qualities: to them the material substances of two bodies are in contact merely, but in this contact of the matter they find footing for the qualities of each.

Their view is plausible because it rejects the notion of total admixture and because it recognizes that the masses of the mixing bodies must be whittled away if there is to be mixture without any gap, if, that is to say, each substance must be divided within itself through and through for complete interpenetration with the other. Their theory is confirmed by the cases in which two mixed substances occupy a greater space than either singly, especially a space equal to the conjoined extent of each: for, as they point out, in an absolute interpenetration the infusion of the one into the other would leave the occupied space exactly what it was before and, where the space occupied is not increased by the juxtaposition, they explain that some expulsion of air has made room for the incoming substance. They ask further, how a minor quantity of one substance can be spread out so as to interpenetrate a major quantity of another. In fact they have a multitude of arguments.

Those, on the other hand, that accept "complete transfusion," might object that it does not require the reduction of the mixed things to fragments, a certain cleavage being sufficient: thus, for instance, sweat does not split up the body or even pierce holes in it. And if it is answered that this may well be a special decree of Nature to allow of the sweat exuding, there is the case of those manufactured articles, slender but without puncture, in which we can see a liquid wetting them through and through so that it runs down from the upper to the under surface. How can this fact be explained, since both the liquid and the solid are bodily substances? Interpenetration without disintegration is difficult to conceive, and if there is such mutual disintegration the two must obviously destroy each other.

When they urge that often there is a mixing without augmentation their adversaries can counter at once with the exit of air.

When there is an increase in the space occupied, nothing refutes the explanation- however unsatisfying- that this is a necessary consequence of two bodies bringing to a common stock their magnitude equally with their other attributes: size is as permanent as any other property; and, exactly as from the blending of qualities there results a new form of thing, the combination of the two, so we find a new magnitude; the blending gives us a magnitude representing each of the two. But at this point the others will answer, "If you mean that substance lies side by side with substance and mass with mass, each carrying its quantum of magnitude, you are at one with us: if there were complete transfusion, one substance sinking its original magnitude in the other, we would have no longer the case of two lines joined end to end by their terminal points and thus producing an increased extension; we would have line superimposed upon line with, therefore, no increase."

But a lesser quantity permeates the entire extent of a larger; the smallest is sunk in the greatest; transfusion is exhibited unmistakably. In certain cases it is possible to pretend that there is no total penetration but there are manifest examples leaving no room for the pretence. In what they say of the spreading out of masses they cannot be thought very plausible; the extension would have to be considerable indeed in the case of a very small quantity ; for they do not suggest any such extension by change as that of water into air.

(3) 'It thought , may I be many, may I grow forth. It sent forth fire . 'That fire thought, may I be many, may I grow forth. It sent forth water . 'And therefore whenever anybody anywhere is hot and perspires, water is produced on him from fire alone.

(1) Iximiprus saith:—I testify that the beginning of all things is a Certain Nature, which is perpetual, coequalling all things, and that the visible natures, with their births and decay, are times wherein the ends to which that nature brings them are beheld and summoned.* Now, I instruct you that the stars are igneous, and are kept within bounds by the air. If the humidity and density of the air did not exist to separate the flames of the sun from living things, then the Sun would consume all creatures. But God has provided the separating air, lest that which He has created should be burnt up. Do you not observe that the Sun when it rises in the heaven overcomes the air by its heat, and that the warmth penetrates from the upper to the lower parts of the air? If, then, the air did not presently breathe forth those winds whereby creatures are generated, the i Sun by its heat would certainly destroy all that lives. But the Sun is kept in check by the air, which thus conquers because it unites the heat of the Sun to its own heat, and the humidity of water to its own humidity. Have you not remarked how tenuous water.

is drawn up into the air by the action of the heat of the Sun, which thus helps the water against itself? If the water did not nourish the air by such tenuous moisture, assuredly the Sun would overcome the air. The fire, therefore, extracts moisture from the water, by means of which the air conquers the fire itself. Thus, fire and water are enemies between which there is no consanguinity, for the fire is hot and dry, but the water is cold and moist.. The air, which is warm and moist, joins these together by its concording medium; between the humidity of water and the heat of fire the air is thus placed to establish peace. And lock ye all how there shall arise a spirit from the tenuous vapour of the air, because the heat being joined to the humour, there necessarily issues something tenuous, which will become a wind. For the heat of the Sun extracts something tenuous out of the air, which also becomes spirit and life to all creatures. All this, however, is disposed in such manner by the will of God, and a coruscation appears when the heat of the Sun touches and breaks up a cloud.

The Turba saith:—Well hast thou described the fire, even as thou knowest concerning it, and thou hast believed the word of thy brother.
