Section 39
CHAPTER XL — OF THE OUTSIDE OF THE WORLD, WHETHER IT IS A VACUUM.
'THE Pythagoreans: outside the world there is a vacuum, into and out of which the world breathes.
'The Stoics: infinite (vacuum), into which the world is also dissolved by the conflagration.
'Poseidonius: not infinite, but sufficiently large for the dissolution.
'Plato, Aristotle: no vacuum either outside the world or inside.'
