one divine spirit." On the contrary, the whole subsists by the power of nature, independently of the Gods, and there is a kind of sympathy (as the Greeks call it) which joins together all the parts of the universe; and the greater that is in its own power, the less is it necessary to have recourse to a divine intelligence.
XII. But how will you get rid of the objections which Carneades made? "If," says he, "there is no body immortal, there is none eternal; but there is no body immortal, nor even indivisible, or that cannot be separated and disunited; and as every animal is in its nature passive, so there is not one which is not subject to the impressions of extraneous bodies; none, that is to say, which can avoid the necessity of enduring and suffering: and if every animal is mortal, there is none immortal; so, likewise, if every animal may be cut up and divided, there is none indivisible, none eternal, but all are liable to be affected by, and compelled to submit to, external power. Every, animal, therefore, is necessarily mortal, dissoluble, and divisible."
For as there is no wax, no silver, no brass which cannot be converted into something else, whatever is composed of wax, or silver, or brass may cease to be what it is. By the same reason, if all the elements are mutable, every body is mutable.
Now, according to your doctrine, all the elements are mutable; all bodies, therefore, are mutable. But if there were any body immortal, then all bodies would not be mutable. Every body, then, is mortal; for every body is either water, air, fire, or earth, or composed of the four elements together, or of some of them. Now, there is not one of all these elements that does not perish; for earthly bodies are fragile: water is so soft that the least shock will separate its parts, and fire and air yield to the least impulse, and are subject to dissolution; besides, any of these elements perish when converted into another nature, as when water is formed from earth, the air from water, and the sky from air, and when they change in the same manner back again. Therefore, if there is nothing but what is perishable in the composition of all animals, there is no animal eternal.
XIII. But, not to insist on these arguments, there is no
