(37) In Meno, Plato, speaking through Socrates, describes color as "an effluence of form, commensurate with sight, and sensible." In Theætetus he discourses more at length on the subject thus: "Let us carry out the principle which has just been affirmed, that nothing is self-existent, and then we shall see that every color, white, black, and every other color, arises out of the eye meeting the appropriate motion, and that what we term the substance of each color is neither the active nor the passive element, but something which passes between them, and is peculiar to each percipient; are you certain that the several colors appear to every animal--say a dog--as they appear to you?"

(47) Moreover, it is the imaging or forming of all sorts of red colours in its own quality; in the sweet it imageth or formeth all sorts of white and blue; in the astringent, or harsh and sour, it formeth all sorts of green, dusky and mixed colours, with all manner of forms or figures and smells.

(3) 'The red colour of the moon is the colour of fire, the white of water, the black of earth. Thus vanishes what we call the moon, as a mere variety, being a name, arising from speech. What is true are the three colours.

(4) 'The red colour of the lightning is the colour of fire, the white of water, the black of earth. Thus vanishes what we call the lightning, as a mere variety, being a name, arising from speech. What is true are the three colours.

(17) Zimon* saith: O Turba of Philosophers and disciples, now hast thou spoken about making into white, but it yet remains to treat concerning the reddening! Know, all ye seekers after this Art, that unless ye whiten, ye cannot make red, because the two natures are nothing other than red and white. Whiten, therefore, the red, and redden the white!* Know, also, that the year is divided into four seasons; the first season is of a frigid complexion, and thisis Winter; the second is of the complexion of air, and this is Spring; then follows the third, which is summer, and is of the complexion of fire; lastly, there is the fourth, wherein fruits are matured, which is Autumn. In this manner, therefore, ye are to rule your natures, namely, to dissolve in winter, to cook in spring, to coagulate in summer, and to gather and tinge the fruit in autumn. Having, therefore, given this example, rule the tingeing natures, but if ye err, blame no one save yourselves.

The Turba answereth: Thou hast treated the matter extremely well; add, therefore, another teaching of this kind for the sake of posterity. And he: I will speak of making lead red.* Take the copper which the Master ordered you to take at the beginning of his book, combine lead therewith, and cook it until it becomes thick; congeal also and desiccate until it becomes red. Here certainly is the Red Lead of which the wise spake; copper and lead become a precious stone; mix them equally, let gold be roasted with them, for this, if ye rule well, becomes a tingeing spirit in spirits.t So when the male and the female are conjoined there is not produced a volatile wife, but a spiritual composite. From the composite turned into a red spirit is produced the beginning of the world.

Behold this is the lead which we have called Red Lead, which is of our work, and without which nothing is effected!

(50) The ancients conceived the spirit of man to correspond with the color blue, the mind with yellow, and the body with red. Heaven is therefore blue, earth yellow, and hell--or the underworld--red. The fiery condition of the inferno merely symbolizes the nature of the sphere or plane of force of which it is composed. In the Greek Mysteries the irrational sphere was always considered as red, for it represented that condition in which the consciousness is enslaved by the lusts and passions of the lower nature. In India certain of the gods--usually attributes of Vishnu--are depicted with blue skin to signify their divine and supermundane constitution. According to esoteric philosophy, blue is the true and sacred color of the sun. The apparent orange-yellow shade of this orb is the result of its rays being immersed in the substances of the illusionary world.

(6) We may now consider the question whether fire is the sole element existing in that celestial realm and whether there is any outgoing thence with the consequent need of renewal.

Timaeus pronounced the material frame of the All to consist primarily of earth and fire for visibility, earth for solidity- and deduced that the stars must be mainly composed of fire, but not solely since there is no doubt they are solid.

And this is probably a true account. Plato accepts it as indicated by all the appearances. And, in fact, to all our perception- as we see them and derive from them the impression of illumination- the stars appear to be mostly, if not exclusively, fire: but on reasoning into the matter we judge that since solidity cannot exist apart from earth-matter, they must contain earth as well.

But what place could there be for the other elements? It is impossible to imagine water amid so vast a conflagration; and if air were present it would be continually changing into fire.

Admitting that two self-contained entities, standing as extremes to each other need for their coherence two intermediaries; we may still question whether this holds good with regard to physical bodies. Certainly water and earth can be mixed without any such intermediate. It might seem valid to object that the intermediates are already present in the earth and the water; but a possible answer would be, "Yes, but not as agents whose meeting is necessary to the coherence of those extremes."

None the less we will take it that the coherence of extremes is produced by virtue of each possessing all the intermediates. It is still not proven that fire is necessary to the visibility of earth and earth to the solidarity of fire.

On this principle, nothing possesses an essential-nature of its very own; every several thing is a blend, and its name is merely an indication of the dominant constituent.

Thus we are told that earth cannot have concrete existence without the help of some moist element- the moisture in water being the necessary adhesive- but admitting that we so find it, there is still a contradiction in pretending that any one element has a being of its own and in the same breath denying its self-coherence, making its subsistence depend upon others, and so, in reality, reducing the specific element to nothing. How can we talk of the existence of the definite Kind, earth- earth essential- if there exists no single particle of earth which actually is earth without any need of water to secure its self-cohesion? What has such an adhesive to act upon if there is absolutely no given magnitude of real earth to which it may bind particle after particle in its business of producing the continuous mass? If there is any such given magnitude, large or small, of pure earth, then earth can exist in its own nature, independently of water: if there is no such primary particle of pure earth, then there is nothing whatever for the water to bind. As for air- air unchanged, retaining its distinctive quality- how could it conduce to the subsistence of a dense material like earth?

Similarly with fire. No doubt Timaeus speaks of it as necessary not to the existence but to the visibility of earth and the other elements; and certainly light is essential to all visibility- we cannot say that we see darkness, which implies, precisely, that nothing is seen, as silence means nothing being heard.

But all this does not assure us that the earth to be visible must contain fire: light is sufficient: snow, for example, and other extremely cold substances gleam without the presence of fire- though of course it might be said that fire was once there and communicated colour before disappearing.

As to the composition of water, we must leave it an open question whether there can be such a thing as water without a certain proportion of earth.

But how can air, the yielding element, contain earth?

Fire, again: is earth perhaps necessary there since fire is by its own nature devoid of continuity and not a thing of three dimensions?

Supposing it does not possess the solidity of the three dimensions, it has that of its thrust; now, cannot this belong to it by the mere right and fact of its being one of the corporeal entities in nature? Hardness is another matter, a property confined to earth-stuff. Remember that gold- which is water- becomes dense by the accession not of earth but of denseness or consolidation: in the same way fire, with Soul present within it, may consolidate itself upon the power of the Soul; and there are living beings of fire among the Celestials.

But, in sum, do we abandon the teaching that all the elements enter into the composition of every living thing?

For this sphere, no; but to lift clay into the heavens is against nature, contrary to the laws of her ordaining: it is difficult, too, to think of that swiftest of circuits bearing along earthly bodies in its course nor could such material conduce to the splendour and white glint of the celestial fire.
