 is best in the whole universe must exist in some complete and perfect being. But nothing is more perfect than the world, and nothing better than virtue. Virtue, therefore, is an attribute of the world. But human nature is not perfect, and nevertheless virtue is produced in it: with how much greater reason, then, do we conceive it to be inherent in the world! Therefore the world has virtue, and it is also wise, and consequently a Deity.

XV. The divinity of the world being now clearly perceived, we must acknowledge the same divinity to be likewise in the stars, which are formed from the lightest and purest part of the ether, without a mixture of any other matter; and, being altogether hot and transparent, we may justly say they have life, sense, and understanding. And Cleanthes thinks that it may be established by the evidence of two of our senses—feeling and seeing—that they are entirely fiery bodies; for the heat and brightness of the sun far exceed any other fire, inasmuch as it enlightens the whole universe, covering such a vast extent of space, and its power is such that we perceive that it not only warms, but often even burns: neither of which it could do if it were not of a fiery quality. Since, then, says he, the sun is a fiery body, and is nourished by the vapors of the ocean (for no fire can continue without some sustenance), it must be either like that fire which we use to warm us and dress our food, or like that which is contained in the bodies of animals.

And this fire, which the convenience of life requires, is the devourer and consumer of everything, and throws into confusion and destroys whatever it reaches. On the contrary, the corporeal heat is full of life, and salutary; and vivifies, preserves, cherishes, increases, and sustains all things, and is productive of sense; therefore, says he, there can be no doubt which of these fires the sun is like, since it causes all things in their respective kinds to flourish and arrive to maturity; and as the fire of the sun is like that which is contained in the bodies of animated beings, the sun itself must likewise be animated, and so must the other stars also, which arise out of the celestial ardor that we call the sky, or firmament.

As, then, some animals are generated in the earth, some
