Pythagoras says that, of his principles, unity is God; and the good, which is indeed the nature of a unity, is mind itself; but the binary number, which is infinite, is a daemon, and evil,--about which the multitude of material beings and this visible world are related. Socrates and Plato agree that God is that which is one, hath its original from its own self, is of a singular subsistence, is one only being perfectly good; all these various names signifying goodness do all centre in mind; hence God is to be understood as that mind and intellect, which is a separate idea, that is to say, pure and unmixed of all matter, and not mingled with anything subject to passions. Aristotle's sentiment is, that God hath his residence in superior regions, and hath placed his throne in the sphere of the universe, and is a separate idea; which sphere is an ethereal body, which is by him styled the fifth essence or quintessence. For there is a division of the universe into spheres, which are contiguous by their nature but appear to reason to be separated; and he concludes that each of the spheres is an animal, composed of a body and soul; the body of them is ethereal, moved orbicularly, the soul is the rational form, which is unmoved, and yet is the cause that the sphere is in motion. The Stoics affirm that God is a thing more common and obvious, and is a mechanic fire which every way spreads itself to produce the world; it contains in itself all seminal virtues, and by this means all things by a fatal necessity were produced. This spirit, passing through the whole world, received different names from the mutations in the matter through which it ran in its journey. God therefore is the world, the stars, the earth, and (highest of all) the mind in the heavens. In the judgment of Epicurus all the gods are anthropomorphites, or have the shape of men; but they are perceptible only by reason, for their nature admits of no other manner of being apprehended, their parts being so small and fine that they give no corporeal representations. The same Epicurus asserts that there are four other natural beings which are immortal: of this sort are atoms, the vacuum, the infinite, and the similar parts; and these last are called Homoeomeries and likewise elements. CHAPTER VIII. OF THOSE THAT ARE CALLED GENIUSES AND HEROES Having treated of the essence of the deities in a just order, it follows that we discourse of daemons and heroes. Thales, Pythagoras, Plato, and the Stoics do conclude that daemons are essences endowed with souls; that the heroes are the souls separated from their bodies, some are good, some are bad; the good are those whose souls are good, the evil those whose souls are wicked. All this is rejected by Epicurus. CHAPTER IX. OF MATTER. Matter is that first being which is substrate for generation, corruption, and all other alterations.
