For through some parts it passes as a “hold” or containing force, as is the case with our bones and sinews; while through others it passes as intelligence, as in the ruling part of the soul. Thus, then, the whole world is a living being, endowed with soul and reason, and having aether for its ruling principle: so says Antipater of Tyre in the eighth book of his treatise On the Cosmos. Chrysippus in the first book of his work On Providence and Posidonius in his book On the Gods say that the heaven, but Cleanthes that the sun, is the ruling power of the world. Chrysippus, however, in the course of the same work gives a somewhat different account, namely, that it is the purer part of the aether; the same which they declare to be preeminently God and always to have, as it were in sensible fashion, pervaded all that is in the air, all animals and plants, and also the earth itself, as a principle of cohesion.
