Chapter V.

Whence Does the World Receive its Nutriment?

Aristotle says that, if the world be nourished, it will likewise be dissolved; but it requires no aliment, and will therefore be eternal. Plato, that this very world prepares for itself a nutriment, by the alteration¹ of those things which are corruptible² in it. Philolaus affirms that a destruction happens to the world in two ways; either by fire failing from heaven, or by the sublunary water being poured down through the whirling of the air; and the exhalations proceeding³ from thence are aliment of the world.
