All things that we consider to be essences are composites; nothing is simple or single, either in works of art, or in the products of nature.[113] Works of art, indeed, contain metal, wood, stone, and are derived from these substances only by the labor of the artist, who, by giving matter its form makes of it a statue, or bed, or house. Among the products of nature, those that are compounds or mixtures may be analyzed into the form impressed on the elements of the compound; so, for instance, we may in a man, distinguish a soul and body, and in the body four elements. Since the very matter of the elements, taken in itself, has no form, every object seems composed of matter and of some principle that supplies it with form.[114] So we are led to ask whence matter derives its form, and to seek whether the soul is simple, or whether it contains two parts, one of which plays the parts of matter, and the other of form,[115] so that the first part would be similar to the form received by the metal of a statue, and the latter to the principle which produces the form itself. THE WORLD-SOUL ALSO IS A COMPOUND OF FORM AND MATTER. Applying this conception to the universe, we rise to Intelligence, recognizing therein the demiurgic creator of the world. It was in receiving from it its shapes by the intermediation of another principle, the universal Soul, that the (material) substances became water, air, earth and fire. On the one hand, the Soul shapes the four elements of the world;[116] on the other, she receives from Intelligence the (seminal) reasons,[117] as the souls of the artists themselves receive from the arts the reasons which they work out.[118] In Intelligence, therefore, there is a part which is the form of the soul; it is intelligence considered, as shape. There is another which imparts shape, like the sculptor who gives the metal the shape of the statue, and which in itself possesses all it gives.[119] Now the (shapes) which the Intelligence imparts to the soul connect with the truth as closely as possible, while those which the soul imparts to the body are only images and appearances.[120] WHY OUR ASCENT CANNOT STOP WITH THE SOUL.
