Second Theory.—Whilst one part of the Universe owes its existence to Providence and is under control of a ruler and governor, another part is abandoned and left to chance. This is the view of Aristotle about Providence... He holds that God controls the spheres and what they contain; therefore the individual beings in the spheres remain permanently in the same form.... From the existence of the spheres other beings derive existence, which are constant in their species but not in their individuals.
