But against this great gift of God, these reasoners, “whose thoughts the Lord knows that they are vain” bring arguments from the weights of the elements; for they have been taught by their master Plato that the two greatest elements of the world, and the furthest removed from one another, are coupled and united by the two intermediate, air and water. And consequently they say, since the earth is the first of the elements, beginning from the base of the
series, the second the water above the earth, the third the air above the water, the fourth the heaven above the air, it follows that a body of earth cannot live in the heaven; for each element is poised by its own weight so as to preserve its own place and rank. Behold with what arguments human infirmity, possessed with vanity, contradicts the omnipotence of God! What, then, do so many earthly bodies do in the air, since the air is the third element from the earth? Unless perhaps He who has granted to the earthly bodies of birds that they be carried through the air by the lightness of feathers and wings, has not been able to confer upon the bodies of men made immortal the power to abide in the highest heaven. The earthly animals, too, which cannot fly, among which are men, ought on these terms to live under the earth, as fishes, which are the animals of the water, live under the water. Why, then, can an animal of earth not live in the second element, that is, in water, while it can in the third? Why, though it belongs to the earth, is it forthwith suffocated if it is forced to live in the second element next above earth, while it lives in the third, and cannot live out of it? Is there a mistake here in the order of the elements, or is not the mistake rather in their reasonings, and not in the nature of things? I will not repeat what I said in the thirteenth book, that many earthly bodies, though heavy like lead, receive from the workman’s hand a form which enables them to swim in water; and yet it is denied that the omnipotent Worker can confer on the human body a property which shall enable it to pass into heaven and dwell there.
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?
