On the Incorruptibility of the World (26-30)

in the first place, in order that the whole might be as far as possible a perfect animal made up of perfect parts. And besides all these things, he ordained that it should be one, inasmuch as there is nothing left out of which another similar world could be composed. Moreover, he willed that it should be exempt from old age, and free from all disease, considering that those things which in the body are hot or cold, or which have mighty powers, if standing all around and falling upon it unseasonably, would be likely to dissolve it, and, by introducing diseases and old age, cause it to decay and perish. For this cause, and because of this reason, God made the whole universe to consist of entire and perfect elements, and exempt from old age and free from disease."

The argument may be stated in a different way as follows. All compound things which are destroyed are dissolved into the elements of which they were compounded; accordingly, dissolution is nothing else but a return of everything to its original constituent parts; just as, on the contrary, composition is that which compels the things combined to come together in a manner contrary to their nature; and indeed, this appears to be the most exact truth;

for men are composed of the four elements which together make up the whole of the universe, the heaven, the earth, the air, and fire, borrowing a few parts of each in a manner at first sight hardly consistent with nature. But the things which are thus combined together are necessarily deprived of a motion in accordance with nature; for instance, warmth is deprived of its upward motion, and coldness of its downward tendency, the earthy and somewhat weighty substance being lightened and assuming the higher place, which the most earth-like of our own parts, the head, has obtained in us.

But of all bonds, that is the worst which is forged by violence, and which, being violent, is also short-lived; for it is speedily broken by those who are bound in it, since they become restive from their desire for a motion in accordance with nature, to which they hasten; for as the tragic poet says, — [*]"And for things sprung from earth, they must Return unto their parent dust, While those from heavenly seed which rise Are borne uplifted to the skies. Nought that has once existed dies, Though often what has been combined Before, we separated find, Invested with another form."
