[88] Nor, again, would it become flame; for that can only exist in connexion with nourishment; and, if nothing is left behind, being deprived of all nourishment it will immediately be extinguished. It follows from all this, that it cannot become light either; for light by itself has no substance at all, but flows from the things before mentioned, coal and flame, not in a great degree from the coal, but very much from the flame; for it is diffused over a very great space indeed. But if, as has been already proved, those things had no existence from the conflagration of all things, then there could not be any light either. For the abundant, and vast, and extensive brilliancy of mid-day, when the sun proceeds under the earth, is at once caused to disappear by night, especially if it be a moonless night. Therefore the world is not destroyed by fire, but is indestructible. And if it should be destroyed by fire, there could not be another created.
