9 It would indeed be easy for us to take a survey of the other elements, the heaven, the air, the earth, the sea, and to show the imbecility of these, and how each requires the assistance of his neighbour, and without this assistance, is lost and destroyed. For as it regards the earth, if the fountains fail it, and the moisture infused from the sea and the rivers, it quickly perishes by being parched. The remaining elements too stand in need of one another, the air of the sun, as well as the sun of the air.
But not to protract this discourse; in what has been said, having given a sufficient supply of reasons to start from for those who are willing to receive them, we shall be content. For if the sun, which is the most surprising part of the whole creation, has been proved to be so feeble and needy, how much more the other parts of the universe? What then I have advanced (offering these things for the consideration of the studious), I will myself again show you in discourse from the Scriptures; and prove, that not only the sun, but also the whole universe is thus corruptible.
For since the elements are mutually destructive, and when much cold intervenes, it chastens the force of the sun's rays; and on the other hand, the heat prevailing, consumes the cold; and since the elements are both the causes and subjects of contrary qualities, and dispositions, in one another; it is very evident that these things offer a proof of great corruptibility; and of the fact, that all these things which are visible, are a corporeal substance.
