(18) There remains the question whether the body possesses any force of its own- so that, with the incoming of the soul, it lives in some individuality- or whether all it has is this Nature we have been speaking of, the superior principle which enters into relations with it.

Certainly the body, container of soul and of nature, cannot even in itself be as a soulless form would be: it cannot even be like air traversed by light; it must be like air storing heat: the body holding animal or vegetive life must hold also some shadow of soul; and it is body thus modified that is the seat of corporeal pains and pleasures which appear before us, the true human being, in such a way as to produce knowledge without emotion. By "us, the true human being" I mean the higher soul for, in spite of all, the modified body is not alien but attached to our nature and is a concern to us for that reason: "attached," for this is not ourselves nor yet are we free of it; it is an accessory and dependent of the human being; "we" means the master-principle; the conjoint, similarly is in its own way an "ours"; and it is because of this that we care for its pain and pleasure, in proportion as we are weak rather than strong, gripped rather than working towards detachment.

The other, the most honourable phase of our being, is what we think of as the true man and into this we are penetrating.

Pleasure and pain and the like must not be attributed to the soul alone, but to the modified body and to something intermediary between soul and body and made up of both. A unity is independent: thus body alone, a lifeless thing, can suffer no hurt- in its dissolution there is no damage to the body, but merely to its unity- and soul in similar isolation cannot even suffer dissolution, and by its very nature is immune from evil.

But when two distinct things become one in an artificial unity, there is a probable source of pain to them in the mere fact that they were inapt to partnership. This does not, of course, refer to two bodies; that is a question of one nature; and I am speaking of two natures. When one distinct nature seeks to associate itself with another, a different, order of being- the lower participating in the higher, but unable to take more than a faint trace of it- then the essential duality becomes also a unity, but a unity standing midway between what the lower was and what it cannot absorb, and therefore a troubled unity; the association is artificial and uncertain, inclining now to this side and now to that in ceaseless vacillation; and the total hovers between high and low, telling, downward bent, of misery but, directed to the above, of longing for unison.

(20) As with bodily pain and pleasure so with the bodily desires; their origin, also, must be attributed to what thus stands midway, to that Nature we described as the corporeal.

Body undetermined cannot be imagined to give rise to appetite and purpose, nor can pure soul be occupied about sweet and bitter: all this must belong to what is specifically body but chooses to be something else as well, and so has acquired a restless movement unknown to the soul and by that acquisition is forced to aim at a variety of objects, to seek, as its changing states demand, sweet or bitter, water or warmth, with none of which it could have any concern if it remained untouched by life.

In the case of pleasure and pain we showed how upon distress follows the knowledge of it, and that the soul, seeking to alienate what is causing the condition, inspires a withdrawal which the member primarily affected has itself indicated, in its own mode, by its contraction. Similarly in the case of desire: there is the knowledge in the sensation and in the next lower phase, that described as the "Nature" which carries the imprint of the soul to the body; that Nature knows the fully formed desire which is the culmination of the less formed desire in body; sensation knows the image thence imprinted upon the Nature; and from the moment of the sensation the soul, which alone is competent, acts upon it, sometimes procuring, sometimes on the contrary resisting, taking control and paying heed neither to that which originated the desire nor to that which subsequently entertained it.

But why, thus, two phases of desire; why should not the body as a determined entity be the sole desirer?

Because there are two distinct things, this Nature and the body, which, through it, becomes a living being: the Nature precedes the determined body which is its creation, made and shaped by it; it cannot originate the desires; they must belong to the living body meeting the experiences of this life and seeking in its distress to alter its state, to substitute pleasure for pain, sufficiency for want: this Nature must be like a mother reading the wishes of a suffering child, and seeking to set it right and to bring it back to herself; in her search for the remedy she attaches herself by that very concern to the sufferer's desire and makes the child's experience her own.

In sum, the living body may be said to desire of its own motion in a fore-desiring with, perhaps, purpose as well; Nature desires for, and because of, that living body; granting or withholding belongs to another again, the higher soul.

(3) For that, in order that a man should be complete in either part, observe that he hath been composed of elements of either part in sets of four;—with hands, and feet, both of them pairs, and with the other members of his body, by means of which he may do service to the lower (that is to say the terrene) world. And to these parts [are added other] four;—of sense, and soul, of memory, and foresight, by means of which he may become acquainted with the rest of things divine, and judge of them. Hence it is brought about that man investigates the differences and qualities, effects and quantities of things, with critical research; yet, as he is held back with the too heavy weight of body’s imperfection, he cannot properly descry the causes of the nature of [all] things which [really] are the true ones.

(2) So, then, although it may do good to few alone, ’tis proper to develope and explain this thesis:—wherefore Divinity hath deigned to share His science and intelligence with men alone. Give ear, accordingly! When God, [our] Sire and Lord, made man, after the Gods, out of an equal mixture of a less pure cosmic part and a divine,—it [naturally] came to pass the imperfections of the cosmic part remained commingled with [our] frames, and other ones [as well], by reason of the food and sustenance we have out of necessity in common with all lives ; by reason of which things it needs must be that the desires, and passions, and other vices, of the mind should occupy the souls of human kind.

(5) Now this Animate might be merely the body as having life: it might be the Couplement of Soul and body: it might be a third and different entity formed from both.

The Soul in turn- apart from the nature of the Animate- must be either impassive, merely causing Sense-Perception in its yoke-fellow, or sympathetic; and, if sympathetic, it may have identical experiences with its fellow or merely correspondent experiences: desire for example in the Animate may be something quite distinct from the accompanying movement or state in the desiring faculty.

The body, the live-body as we know it, we will consider later.

Let us take first the Couplement of body and Soul. How could suffering, for example, be seated in this Couplement?

It may be suggested that some unwelcome state of the body produces a distress which reaches to a Sensitive-Faculty which in turn merges into Soul. But this account still leaves the origin of the sensation unexplained.

Another suggestion might be that all is due to an opinion or judgement: some evil seems to have befallen the man or his belongings and this conviction sets up a state of trouble in the body and in the entire Animate. But this account leaves still a question as to the source and seat of the judgement: does it belong to the Soul or to the Couplement? Besides, the judgement that evil is present does not involve the feeling of grief: the judgement might very well arise and the grief by no means follow: one may think oneself slighted and yet not be angry; and the appetite is not necessarily excited by the thought of a pleasure. We are, thus, no nearer than before to any warrant for assigning these affections to the Couplement.

Is it any explanation to say that desire is vested in a Faculty-of-desire and anger in the Irascible-Faculty and, collectively, that all tendency is seated in the Appetitive-Faculty? Such a statement of the facts does not help towards making the affections common to the Couplement; they might still be seated either in the Soul alone or in the body alone. On the one hand if the appetite is to be stirred, as in the carnal passion, there must be a heating of the blood and the bile, a well-defined state of the body; on the other hand, the impulse towards The Good cannot be a joint affection, but, like certain others too, it would belong necessarily to the Soul alone.

Reason, then, does not permit us to assign all the affections to the Couplement.

In the case of carnal desire, it will certainly be the Man that desires, and yet, on the other hand, there must be desire in the Desiring-Faculty as well. How can this be? Are we to suppose that, when the man originates the desire, the Desiring-Faculty moves to the order? How could the Man have come to desire at all unless through a prior activity in the Desiring-Faculty? Then it is the Desiring-Faculty that takes the lead? Yet how, unless the body be first in the appropriate condition?
