But against what I have formerly said they can find nothing to say, even though they introduce and make the most of this order of the elements in which they confide. For if the order be that the earth is first, the water second, the air third, the heaven fourth, then the soul is above all. For Aristotle said that the soul was a fifth body, while Plato denied that it was a body at all. If it were a fifth body, then certainly it would be above the rest; and if it is not a body at all, so much the more does it rise above all. What, then, does it do in an earthly body? What does this soul, which is finer than all else, do in such a mass of matter as this? What does the lightest of substances do in this ponderosity? this swiftest substance in such sluggishness? Will not the body be raised to heaven by virtue of so excellent a nature as this? and if now earthly bodies can retain the souls below, shall not the souls be one day able to raise the earthly bodies above?
