Complete Works of Plutarch — Volume 3: Essays and Miscellanies

by Plutarch

He says sometimes, that the air is light and mounts upwards, and sometimes, that it is neither heavy nor light. For in his Second Book of Motion he says, that the fire, being without gravity, ascends upwards, and the air like to that; the water approaching more to the earth, and the air to the fire. But in his Physical Arts he inclines to the other opinion, that the air of itself has neither gravity nor levity.

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 immunity from corruption, because it is in the midst; since if it were conceived to be anywhere else, corruption would absolutely happen to 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 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 arts 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 concerns itself, and the parts being 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.

And these things indeed contain great contradictions to natural reason; but this is also repugnant to the doctrine concerning God and Providence, that assigning to them the least causes, he takes from them the most principal and greatest. For what is more principal than the permanency of the world, or that its essence, united in its parts, is contained in itself? But this, as Chrysippus says, fell out casually. For if the possession of place is the cause of incorruptibility, and this was the production of chance, it is manifest that the preservation of the universe is a work of chance, and not of Fate and Providence.

Now, as for his doctrine of possibles, how can it but be repugnant to his doctrine of Fate? For if that is not possible which either is true or shall be true, as Diodorus has it, but everything which is capable of being, though it never shall be, is possible, there will be many things possible which will never be according to invincible, inviolable, and all-conquering Fate. And thus either Fate will lose its power; or if that, as Chrysippus thinks, has existence, that which is susceptible of being will often fall out to be impossible. And everything indeed which is true will be necessary, being comprehended by the principal of all necessities; and everything that is false will be impossible, having the greatest cause to oppose its ever being true. For how is it possible that he should be susceptible of dying on the land, who is destined to die at sea? And how is it possible for him who is at Megara to come to Athens, if he is prohibited by Fate?

But moreover, the things that are boldly asserted by him concerning fantasies or imaginations are very opposite to Fate. For desiring to show that fantasy is not of itself a perfect cause of consent, he says, that the Sages will prejudice us by imprinting false imaginations in our minds, if fantasies do of themselves absolutely cause consent; for wise men often make use of falsity against the wicked, representing a probable imagination,—which is yet not the cause of consent, for then it would be also a cause of false apprehension and error. Any one therefore, transferring these things from the wise man to Fate, may say, that consents are not caused by Fate; for if they were, false consents and opinions and deceptions would also be by Fate. Thus the reason which exempts the wise man from doing hurt also demonstrates at the same time that Fate is not the cause of all things. For if men neither opine nor are prejudiced by Fate, it is manifest also that they neither act rightly nor are wise nor remain firm in their sentiments nor have utility by Fate, but that there is an end of Fate's being the cause of all things. Now if any one shall say that Chrysippus makes not Fate the absolute cause of all things, but only a PROCATARCLICAL (or antecedent) one, he will again show that he is contradictory to himself, since he excessively praises Homer for saying of Jupiter,

Receive whatever good or ill
He sends to each of you;

as also Euripides for these words,

O Jove, how can I say that wretched we,
Poor mortals, aught do understand? On thee
We all depend, and nothing can transact,
But as thy sacred wisdom shall enact.
(Euripides, "Suppliants," 734.)

And himself writes many things agreeable to these. In fine, he says that nothing, be it never so little, either rests or is moved otherwise than according to the reason of Jupiter, which is the same thing with Fate. Moreover, the antecedent cause is weaker than the absolute one, and attains not to its effect when it is subdued by others that rise up against it. But he himself declaring Fate to be an invincible, unimpeachable, and inflexible cause, calls it Atropos, (That is, Unchangeable.) Adrasteia, (That is, Unavoidable.) Necessity, and Pepromene (as putting a limit to all things). Whether then shall we say, that neither consents nor virtues nor vices nor doing well nor doing ill is in our power? Or shall we affirm, that Fate is deficient, that terminating destiny is unable to determine, and that the motions and habits of Jupiter cannot be effective? For the one of these two consequences will follow from Fate's being an absolute, the other from its being only an antecedent cause. For if it is an absolute cause, it takes away our free will and leaves nothing in our control; and if it is only antecedent, it loses its being unimpeachable and effectual. For not once or ten times, but everywhere, especially in his Physics, he has written, that there are many obstacles and impediments to particular natures and motions, but none to that of the universe. And how can the motion of the universe, extending as it does to particular ones, be undisturbed and unimpeached, if these are stopped and hindered? For neither can the nature of man be free from impediment, if that of the foot or hand is not so; nor can the motion of a ship but be hindered, if there are any obstacles about the sails or the operation of the oars.
