On the Incorruptibility of the World (126-130)

And so also the corruptions of the air are plain to everyone, for it is the nature of the atmosphere to become sick and to decay, and, as one may say, in a manner to die; since what else is it which a man, who is not aiming at selecting plausible language, but only at truth, would call a plague except a death of the atmosphere, which diffuses its own disease and suffering to the destruction of everything which is endowed with life?

And why need I speak at great length concerning fire? for if it is deprived of nourishment it is immediately extinguished, becoming, as the poets say, tame by its own natural qualities, on which account it depends upon, and is raised up by the duration of the fuel which is supplied and kindled, but when that is expended the fire also disappears.

And they say that the dragons in India are exposed to the same kind of fate, for that they crawl upon the greatest of all beasts, namely elephants, and creep over their backs and the whole of their bellies, and then, if they can find a vein, they divide that and

since the dragons have no longer any nourishment, they attempt to loosen the bonds with which they twined themselves round the elephants, wishing now to get released from them, but they are pressed down by the weight of the elephants and crushed, and much more so when the animal has become a lifeless, hard, and stone-like substance; for though they wriggle about and try every expedient in order to effect their release from the power of the animal which weighs them down, and by which they are entangled, though they have long practised themselves in every variety of wile, amid all kinds of difficulties and distresses, they at last become too weak to resist, like men who have been starved to death, or who have been caught by a wall which has suddenly fallen down upon them, and not being able even to lift up their heads they die of suffocation. If then, each of the separate parts of the world awaits utter destruction, it is plain that the world which is compounded of these can not be itself exempt from destruction.

We must now consider with accuracy the fourth and remaining argument. Thus they argue: if the world were eternal then the animals also would be eternal, and much more the human race, in proportion as that is more excellent than the other animals; but, on the contrary, those who take delight in investigating the mysteries of nature consider that man has only been created in the late ages of the world; for it is likely, or I should rather say it is inevitably true, that the arts co-exist with man, so as to be exactly co-eval with him, not only because methodical proceedings are appropriate to a rational nature, but also because it is not possible to live without them;
