De Stoicorum repugnantiis

He says, that the infant in the womb is nourished by Nature, like a plant; but when it is brought forth, being cooled and hardened by the air, it changes its spirit and becomes an animal; whence the soul is not unfitly named Psyche because of this refrigeration (ψύχειν). But again he esteems the soul the more subtile and fine spirit of Nature, therein contradicting himself; for how can a subtile thing be made of a gross one, and be rarefied by refrigeration and condensation? And what is more, how does he, declaring an animal to be made by refrigeration, think the sun to be animated, which is of fire and made of an exhalation changed into fire? For he says in his Third Book of Nature: Now the change of fire is such, that it is turned by the air into water; and the earth subsiding from this, the air exhales; the air being subtilized, the ether is produced round about it; and the stars are, with the sun, kindled from the sea. Now what is more contrary to kindling than refrigeration, or to rarefaction than condensation? For the one makes water and earth of fire and air, and the other changes that which is moist and earthy into fire and air. But yet in one place he makes kindling, in another cooling, to be the beginning of animation. And he moreover says, that when the inflammation is throughout, it lives and is an animal, but being again extinct and thickened, it is turned into water and earth and corporeity. Now in his First Book of Providence he says: For the world, indeed, being wholly set on fire, is presently also the soul and guide of itself; but when it is changed into moisture, and has changed the soul remaining within it in some sort into a body and soul, so as to consist of these two, it is then after another manner. Here, forsooth, he plainly says, that the inanimate parts of the world are by

inflammation turned into an animated thing, and that again by extinction the soul is relaxed and moistened, being changed into corporeity. He seems therefore very absurd, one while by refrigeration making animals of senseless things, and again, by the same changing the greatest part of the world’s soul into senseless and inanimate things.

But besides this, his discourse concerning the generation of the soul has a demonstration contrary to his own opinion; for he says, that the soul is generated when the infant is already brought forth, the spirit being changed by refrigeration, as by hardening. Now for the soul’s being engendered, and that after the birth, he chiefly uses this demonstration, that the children are for the most part in manners and inclinations like to their parents. Now the repugnancy of these things is evident. For it is not possible that the soul, which is not generated till after the birth, should have its inclination before the birth; or it will fall out that the soul is like before it is generated; that is, it will be in likeness, and yet not be, because it is not yet generated. But if any one says that, the likeness being bred in the tempers of the bodies, the souls are changed when they are generated, he destroys the argument of the soul’s being generated. For thus it may come to pass, that the soul, though not generated, may at its entrance into the body be changed by the mixture of likeness.

He says that the air is by nature dark, and uses this

as an argument of its being also the first cold; for that its darkness is opposite to the brightness, and its coldness to the heat of fire. Moving this in his First Book of Natural Questions, he again in his treatise of Habits says, that habits are nothing else but airs; for bodies are contained by these, and the cause that every one of the bodies contained in any habit is such as it is, is the containing air, which they call in iron hardness, in stone solidness, in silver whiteness. These words have in them much absurdity and contradiction. For if the air remains such as it is of its own nature, how comes black, in that which is not white, to be made whiteness; and soft, in that which is not hard, to be made hardness; and rare, in that which is not thick, to be made thickness? But if, being mixed with these, it is altered and made like to them, how is it a habit or power or cause of these things by which it is subdued? For such a change, by which it loses its own qualities, is the property of a patient, not of an agent, and not of a thing containing, but of a thing languishing. Yet they everywhere affirm, that matter, being of its own nature idle and motionless, is subjected to qualities, and that the qualities are spirits, which, being also aerial tensions, give a form and figure to every part of matter to which they adhere. These things they cannot rationally say, supposing the air to be such as they affirm it. For if it is a habit and tension, it will assimilate every body to itself, so that it shall be black and soft. But if by the mixture with these things it receives forms contrary to those it has, it will be in some sort the matter, and not the cause or power of matter.

It is often said by Chrysippus, that there is without the world an infinite vacuum, and that this infinity has neither beginning, middle, nor end. And by this the Stoics chiefly refute that spontaneous motion of the atoms downward, which is taught by Epicurus; there not being in

infinity any difference according to which one thing is thought to be above, another below. But in his Fourth Book of Things Possible, having supposed a certain middle place and middle region, he says that the world is situated there. The words are these: Wherefore, if it is to be said of the world that it is corruptible, this seems to want proof; yet nevertheless it rather appears to me to be so. However, its occupation of the place wherein it stands cooperates very much towards its seeming to be incorruptible, because it is in the midst; since if it were thought to be anywhere else, corruption would absolutely take hold of it. And again, a little after: For so also in a manner has essence happened eternally to possess the middle place, being immediately from the beginning such as it is; so that both by another manner and through this chance it admits not any corruption, and is therefore eternal. These words have one apparent and visible contradiction, to wit, his admitting a certain middle place and middle region in infinity. They have also a second, more obscure indeed, but withal more absurd than this. For thinking that the world would not have remained incorruptible if its situation had happened to have been in any other part of the vacuum, he manifestly appears to have feared lest, the parts of essence moving towards the middle, there should be a dissolution and corruption of the world. Now this he would not have feared, had he not thought that bodies do by nature tend from every place towards the middle, not of essence, but of the region containing essence; of which also he has frequently spoken, as of a thing impossible and contrary to Nature; for that (as he says) there is not in the vacuum any difference by which bodies are drawn rather this way than that way, but the construction of the world is the cause of motion, bodies inclining and being carried from every side to the centre and middle of it. It is sufficient to this purpose, to set down the text out of his Second Book of Motion; for having discoursed, that the world indeed is a perfect body, but that the parts of the world are not perfect, because they have in some sort respect to the whole and are not of themselves; and going forward concerning its motion, as having been framed by Nature to be moved by all its parts towards compaction and cohesion, and not towards dissolution and breaking, he says thus: But the universe thus tending and being moved to the same point, and the parts having the same motion from the nature of the body, it is probable that all bodies have this first motion according to Nature towards the centre of the world,—the world being thus moved as regards itself, and the parts being thus moved as being its parts. What then ailed you, good sir (might some one say to him), that you have so far forgotten those words, as to affirm that the world, if it had not casually possessed the middle place, would have been dissoluble and corruptible? For if it is by Nature so framed as always to incline towards the middle, and its parts from every side tend to the same, into what place soever of the vacuum it should have been transposed,—thus containing and (as it were) embracing itself,—it would have remained incorruptible and without danger of breaking. For things that are broken and dissipated suffer this by the separation and dissolution of their parts, every one of them hasting to its own place from that which it had contrary to Nature. But you, being of opinion that, if the world should have been seated in any other place of the vacuum, it would have been wholly liable to corruption, and affirming the same, and therefore asserting a middle in that which naturally can have no middle,— to wit, in that which is infinite,—have indeed dismissed these tensions, coherences, and inclinations, as having nothing available to its preservation, and attributed all the cause of its permanency to the possession of place. And, as if you were ambitious to confute yourself, to the things you have said before you join this also: In whatsoever manner every one of the parts moves, being coherent to the rest, it is agreeable to reason that in the same also the whole should move by itself; yea, though we should, for argument’s sake, imagine and suppose it to be in some vacuity of this world; for as, being kept in on every side, it would move towards the middle, so it would continue in the same motion, though by way of disputation we should admit that there were on a sudden a vacuum round about it. No part then whatsoever, though encompassed by a vacuum, loses its inclination moving it towards the middle of the world; but the world itself, if chance had not prepared it a place in the middle, would have lost its containing vigor, the parts of its essence being carried some one way, some another.
