[102] and it is easy to see the truth of what is here said. Every body, when it is resolved into fire, is dissolved, and melted, and diffused; and when the flame which is in it is extinguished, it is then contracted and shrunk up to nothing; but there is no need of arguments to prove a thing which is so clear, as if it were obscure; and, indeed, the world, if consumed by fire, will become greater, inasmuch as all its essence will then be dissolved into the thinnest air; and it appears to me that the Stoics have foreseen this, and on that account have, in their arguments, assumed that a vacuum of infinite extent will be left abandoned on the outside of the world; that so, since it is fated to be subjected to a certain diffusion of boundless extent, it may not be in want of a place which may be capable of receiving that diffusion.
