CHAPTER VIII. WHAT IS THE CAUSE OF THE WORLD'S INCLINATION.
Diogenes and Anaxagoras state that, after the world was composed and had produced living creatures, the world out of its own propensity made an inclination toward the south. Perhaps this may be attributed to a wise Providence (they affirm), that thereby some parts of the world may be habitable, others uninhabitable, according as the various climates are affected with a rigorous cold, or a scorching heat, or a just temperament of cold and heat. Empedocles, that the air yielding to the impetuous force of the solar rays, the poles received an inclination; whereby the northern parts were exalted and the southern depressed, by which means the whole world received its inclination.
CHAPTER IX. 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 infinite space 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 a vacuum does not exist. Plato concludes that neither within nor without the world there is any vacuum.
CHAPTER X. WHAT PARTS OF THE WORLD ARE ON THE RIGHT HAND, AND WHAT ON THE LEFT.
Pythagoras, Plato, and Aristotle declare that the eastern parts of the world, from whence motion commences, are of the right, those of the western are of the left hand of the world. Empedocles, that those that are of the right hand face the summer solstice, those of the left the winter solstice.
