(15) And when the Taste has tried it, and if it be good for the Essences of the Soul, then it gives it to the Feeling, which must try what Quality it is of, whether hot or cold, hard or soft, thick or thin, and then the Feeling a sends it into the Heart, [presenting it] before the Flash of the Life, and before the King of the Light of Life; and the Will of the Mind pierces further into that Thing, a great Depth, and sees what is therein, [considering] how much it will receive and take in of that Thing, and when it is enough, then the Will gives it to the Spirit of the Soul, viz. to the eternal Emperor, who brings it (with his strong and austere Might) out of the Heart, in the Sound upon the Tongue under the Roof of the Mouth, and there the Spirit distinguishes according to the Senses, as the Will has discovered [or manifested] it, and the Tongue distinguishes it in the Noise.

(14) First the King gives it to the Eyes, to see whether it be Good or Evil; and the Eyes give it to the Ears, to hear from whence it comes, whether out of a true, or out of a false Region, and whether it be a Lie or Truth; and the Ears give it to the Nose, (the Smell,) that must smell, whether that which is brought in (and stands before the King) comes out of a good or uevil Essence; and the Nose gives it to the Taste, which must try whether it be pure or impure, and therefore the Taste has the Tongue, that it may spit it out again if it be impure; but if it be a Thought to [be expressed in] a Word, then the Lips are the Door-keepers, which must keep it shut, and not let the Tongue forth, but must bring it into the Region of the Air, into the Nostrils, and not into the Heart, and stifle it, and then it is dead.

(16) For the Region of the Air must here drive the Work through the Throat, where then all the Veins in the whole Body tend and concur, and bring the Virtue of the noble Tincture towards that, and mingle themselves with the Word; and there also all the three Regions of the Mind come, and mingle themselves with the Distinguishing, [Framing, Articulating, or Separating] of Words; and there is a very wonderful Form, [or Manner of Work.] For every Region [or Dominion] will distinguish [or separate] the Word according to its Essences, for the Sound goes out of the Heart, out of all three Principles.

(79) Timaeus: and lays hold on the meats and drinks, it dissolves them, and dividing them into small particles it disperses them through the outlets by which it passes and draws them off to the veins, like water drawn into channels from a spring; and thus it causes the streams of the veins to flow through the body as through a pipe. Once again let us consider the process of respiration, and the causes in virtue of which it has come to be such as it now is.

(23) I explain: A living body is illuminated by soul: each organ and member participates in soul after some manner peculiar to itself; the organ is adapted to a certain function, and this fitness is the vehicle of the soul-faculty under which the function is performed; thus the seeing faculty acts through the eyes, the hearing faculty through the ears, the tasting faculty through the tongue, the faculty of smelling through the nostrils, and the faculty of sentient touch is present throughout, since in this particular form of perception the entire body is an instrument in the soul's service.

The vehicles of touch are mainly centred in the nerves- which moreover are vehicles of the faculty by which the movements of the living being are affected- in them the soul-faculty concerned makes itself present; the nerves start from the brain. The brain therefore has been considered as the centre and seat of the principle which determines feeling and impulse and the entire act of the organism as a living thing; where the instruments are found to be linked, there the operating faculty is assumed to be situated. But it would be wiser to say only that there is situated the first activity of the operating faculty: the power to be exercised by the operator- in keeping with the particular instrument- must be considered as concentrated at the point at which the instrument is to be first applied; or, since the soul's faculty is of universal scope the sounder statement is that the point of origin of the instrument is the point of origin of the act.

Now, the faculty presiding over sensation and impulse is vested in the sensitive and representative soul; it draws upon the Reason-Principle immediately above itself; downward, it is in contact with an inferior of its own: on this analogy the uppermost member of the living being was taken by the ancients to be obviously its seat; they lodged it in the brain, or not exactly in the brain but in that sensitive part which is the medium through which the Reason-Principle impinges upon the brain. They saw that something must be definitely allocated to body- at the point most receptive of the act of reason- while something, utterly isolated from body must be in contact with that superior thing which is a form of soul of that soul apt to the appropriation of the perceptions originating in the Reason-Principle.

Such a linking there must be, since in perception there is some element of judging, in representation something intuitional, and since impulse and appetite derive from representation and reason. The reasoning faculty, therefore, is present where these experiences occur, present not as in a place but in the fact that what is there draws upon it. As regards perception we have already explained in what sense it is local.

But every living being includes the vegetal principle, that principle of growth and nourishment which maintains the organism by means of the blood; this nourishing medium is contained in the veins; the veins and blood have their origin in the liver: from observation of these facts the power concerned was assigned a place; the phase of the soul which has to do with desire was allocated to the liver. Certainly what brings to birth and nourishes and gives growth must have the desire of these functions. Blood- subtle, light, swift, pure- is the vehicle most apt to animal spirit: the heart, then, its well-spring, the place where such blood is sifted into being, is taken as the fixed centre of the ebullition of the passionate nature.

(1) IF we consider now the Springing up of the Life, and in what Place of the Body it is where the Life is generated, then we shall rightly find the whole Ground of Man, and there is nothing so secret in Man but that it may be found. For we must needs say, that the Heart is the Place, wherein the noble Life is generated, and the Life again penetrates the Heart.

(78) Timaeus: its streams as well should be plenished from this. The rest of the enveloping mesh-work He made to grow round all the hollow part of our body; and He caused all this at one time to flow gently into the inner-weels, seeing they were of air, and at another time the weels to flow back into it. And inasmuch as the body was porous, He caused the veil to pass in through it and out again; and the inner rays of fire that were enclosed within it He made to follow the air as it moved in either direction; whence it comes that, so long as the mortal living creature preserves its structure, this process goes on unceasingly.
