(8) A. There are those who insist on the activities observed in bodies- warming, chilling, thrusting, pressing- and class soul with body, as it were to assure its efficacy. This ignores the double fact that the very bodies themselves exercise such efficiency by means of the incorporeal powers operating in them, and that these are not the powers we attribute to soul: intellection, perception, reasoning, desire, wise and effective action in all regards, these point to a very different form of being.

In transferring to bodies the powers of the unembodied, this school leaves nothing to that higher order. And yet that it is precisely in virtue of bodiless powers that bodies possess their efficiency is clear from certain reflections:

It will be admitted that quality and quantity are two different things, that body is always a thing of quantity but not always a thing of quality: matter is not qualified. This admitted, it will not be denied that quality, being a different thing from quantity, is a different thing from body. Obviously quality could not be body when it has not quantity as all body must; and, again, as we have said, body, any thing of mass, on being reduced to fragments, ceases to be what it was, but the quality it possessed remains intact in every particle- for instance the sweetness of honey is still sweetness in each speck- this shows that sweetness and all other qualities are not body.

Further: if the powers in question were bodies, then necessarily the stronger powers would be large masses and those less efficient small masses: but if there are large masses with small while not a few of the smaller masses manifest great powers, then the efficiency must be vested in something other than magnitude; efficacy, thus, belongs to non-magnitude. Again; Matter, they tell us, remains unchanged as long as it is body, but produces variety upon accepting qualities; is not this proof enough that the entrants are Reason-Principles and not of the bodily order?

They must not remind us that when pneuma and blood are no longer present, animals die: these are necessary no doubt to life, but so are many other things of which none could possibly be soul: and neither pneuma nor blood is present throughout the entire being; but soul is.

(4) Our opponents themselves are driven by stress of fact to admit the necessity of a prior to body, a higher thing, some phase or form of soul; their "pneuma" is intelligent, and they speak of an "intellectual fire"; this "fire" and "spirit" they imagine to be necessary to the existence of the higher order which they conceive as demanding some base, though the real difficulty, under their theory, is to find a base for material things whose only possible base is, precisely, the powers of soul.

Besides, if they make life and soul no more than this "pneuma," what is the import of that repeated qualification of theirs "in a certain state," their refuge when they are compelled to recognize some acting principle apart from body? If not every pneuma is a soul, but thousands of them soulless, and only the pneuma in this "certain state" is soul, what follows? Either this "certain state," this shaping or configuration of things, is a real being or it is nothing.

If it is nothing, only the pneuma exists, the "certain state" being no more than a word; this leads imperatively to the assertion that Matter alone exists, Soul and God mere words, the lowest alone is.

If on the contrary this "configuration" is really existent- something distinct from the underlie or Matter, something residing in Matter but itself immaterial as not constructed out of Matter, then it must be a Reason-Principle, incorporeal, a separate Nature.

There are other equally cogent proofs that the soul cannot be any form of body.

Body is either warm or cold, hard or soft, liquid or solid, black or white, and so on through all the qualities by which one is different from another; and, again, if a body is warm it diffuses only warmth, if cold it can only chill, if light its presence tells against the total weight which if heavy it increases; black, it darkens; white, it lightens; fire has not the property of chilling or a cold body that of warming.

Soul, on the contrary, operates diversely in different living beings, and has quite contrary effects in any one: its productions contain the solid and the soft, the dense and the sparse, bright and dark, heavy and light. If it were material, its quality- and the colour it must have- would produce one invariable effect and not the variety actually observed.

(5) Again, there is movement: all bodily movement is uniform; failing an incorporeal soul, how account for diversity of movement? Predilections, reasons, they will say; that is all very well, but these already contain that variety and therefore cannot belong to body which is one and simplex, and, besides, is not participant in reason- that is, not in the sense here meant, but only as it is influenced by some principle which confers upon it the qualities of, for instance, being warm or cold.

Then there is growth under a time-law, and within a definite limit: how can this belong strictly to body? Body can indeed be brought to growth, but does not itself grow except in the sense that in the material mass a capacity for growing is included as an accessory to some principle whose action upon the body causes growth.

Supposing the soul to be at once a body and the cause of growth, then, if it is to keep pace with the substance it augments, it too must grow; that means it must add to itself a similar bodily material. For the added material must be either soul or soulless body: if soul, whence and how does it enter, and by what process is it adjoined ; if soulless, how does such an addition become soul, falling into accord with its precedent, making one thing with it, sharing the stored impressions and notions of that initial soul instead, rather, of remaining an alien ignoring all the knowledge laid up before?

Would not such a soulless addition be subject to just such loss and gain of substance, in fact to the non-identity, which marks the rest of our material mass?

And, if this were so, how explain our memories or our recognition of familiar things when we have no stably identical soul?

Assume soul to be a body: now in the nature of body, characteristically divisible, no one of the parts can be identical with the entire being; soul, then, is a thing of defined size, and if curtailed must cease to be what it is; in the nature of a quantitative entity this must be so, for, if a thing of magnitude on diminution retains its identity in virtue of its quality, this is only saying that bodily and quantitatively it is different even if its identity consists in a quality quite independent of quantity.

What answer can be made by those declaring soul to be corporeal? Is every part of the soul, in any one body, soul entire, soul perfectly true to its essential being? and may the same be said of every part of the part? If so, the magnitude makes no contribution to the soul's essential nature, as it must if soul were a definite magnitude: it is, as body cannot be, an "all-everywhere," a complete identity present at each and every point, the part all that the whole is.

To deny that every part is soul is to make soul a compound from soulless elements. Further, if a definite magnitude, the double limit of larger or smaller, is to be imposed upon each separate soul, then anything outside those limits is no soul.

Now, a single coition and a single sperm suffice to a twin birth or in the animal order to a litter; there is a splitting and diverging of the seed, every diverging part being obviously a whole: surely no honest mind can fail to gather that a thing in which part is identical with whole has a nature which transcends quantity, and must of necessity be without quantity: only so could it remain identical when quantity is filched from it, only by being indifferent to amount or extension, by being in essence something apart. Thus the Soul and the Reason-Principles are without quantity.

(29) But- keeping to our illustration, by which the body is warmed by soul and not merely illuminated by it- how is it that when the higher soul withdraws there is no further trace of the vital principle?

For a brief space there is; and, precisely, it begins to fade away immediately upon the withdrawal of the other, as in the case of warmed objects when the fire is no longer near them: similarly hair and nails still grow on the dead; animals cut to pieces wriggle for a good time after; these are signs of a life force still indwelling.

Besides, simultaneous withdrawal would not prove the identity of the higher and lower phases: when the sun withdraws there goes with it not merely the light emanating from it, guided by it, attached to it, but also at once that light seen upon obliquely situated objects, a light secondary to the sun's and cast upon things outside of its path ; the two are not identical and yet they disappear together.

But is this simultaneous withdrawal or frank obliteration?

The question applies equally to this secondary light and to the corporeal life, that life which we think of as being completely sunk into body.

No light whatever remains in the objects once illuminated; that much is certain; but we have to ask whether it has sunk back into its source or is simply no longer in existence.

How could it pass out of being, a thing that once has been?

But what really was it? We must remember that what we know as colour belongs to bodies by the fact that they throw off light, yet when corruptible bodies are transformed the colour disappears and we no more ask where the colour of a burned-out fire is than where its shape is.

Still: the shape is merely a configuration, like the lie of the hands clenched or spread; the colour is no such accidental but is more like, for example, sweetness: when a material substance breaks up, the sweetness of what was sweet in it, and the fragrance of what was fragrant, may very well not be annihilated, but enter into some other substance, passing unobserved there because the new habitat is not such that the entrant qualities now offer anything solid to perception.

May we not think that, similarly, the light belonging to bodies that have been dissolved remains in being while the solid total, made up of all that is characteristic, disappears?

It might be said that the seeing is merely the sequel to some law , so that what we call qualities do not actually exist in the substances.

But this is to make the qualities indestructible and not dependent upon the composition of the body; it would no longer be the Reason-Principles within the sperm that produce, for instance, the colours of a bird's variegated plumage; these principles would merely blend and place them, or if they produced them would draw also on the full store of colours in the sky, producing in the sense, mainly, of showing in the formed bodies something very different from what appears in the heavens.

But whatever we may think on this doubtful point, if, as long as the bodies remain unaltered, the light is constant and unsevered, then it would seem natural that, on the dissolution of the body, the light- both that in immediate contact and any other attached to that- should pass away at the same moment, unseen in the going as in the coming.

But in the case of the soul it is a question whether the secondary phases follow their priors- the derivatives their sources- or whether every phase is self-governing, isolated from its predecessors and able to stand alone; in a word, whether no part of the soul is sundered from the total, but all the souls are simultaneously one soul and many, and, if so, by what mode; this question, however, is treated elsewhere.

Here we have to enquire into the nature and being of that vestige of the soul actually present in the living body: if there is truly a soul, then, as a thing never cut off from its total, it will go with soul as soul must: if it is rather to be thought of as belonging to the body, as the life of the body, we have the same question that rose in the case of the vestige of light; we must examine whether life can exist without the presence of soul, except of course in the sense of soul living above and acting upon the remote object.

(27) But, neither is the Evil in bodies. For deformity and disease are a defect of form, and a deprivation of order. And this is not altogether an evil, but a less good; for if a dissolution of beauty and form and order become complete, the body itself will be gone. But that the body is not cause of baseness to the soul is evident, from the fact that baseness continues to coexist even without a body, as in demons. For this is evil to minds and souls and bodies, (viz.) the weakness and declension from the habitude of their own proper goods.
