OF THAT THING WHICH IS BEYOND THE WORLD, AND WHETHER IT BE A VACUUM OR
NOT.
Pythagoras and his followers say that beyond the world there is a
vacuum, into which and out of which the world hath its respiration.
The Stoics, that there is a vacuum into which the infinite world by a
conflagration shall be dissolved. Posidonius, not an infinite vacuum,
but as much as suffices for the dissolution of the world; and this he
asserts in his first book concerning the Vacuum. Aristotle affirms,
that there is no vacuum. Plato concludes that neither within nor
without the world there is any vacuum.
