14. Can we identify the nature that contains all the intelligibles (Intelligence) with the supreme Principle? Impossible, because the supreme Principle must be essentially one, and simple, while essences form a multitude. But as these essences form a multitude, we are forced to explain how this multitude, and all these essences can exist. How can (the single) Intelligence be all these things? Whence does it proceed? This we shall have to study elsewhere.[146] THE SOUL RECEIVES ACCIDENTS FROM MATTER, BUT DEFECTS ARE NOT IN THE INTELLIGIBLE. It may further be asked whether the intelligible world contains the ideas of objects which are derived from decay, which are harmful or disagreeable, such as, for instance, mud or excreta. We answer that all the things that universal Intelligence receives from the First are excellent. Among them are not found ideas of those dirty and vile objects mentioned above; Intelligence does not contain them. But though receiving from Intelligence ideas, the soul receives from matter other things, among which may be found the above-mentioned accidents. Besides, a more thorough answer to this question must be sought for in our book where we explain "How the Multitude of Ideas Proceeds from the One."[147] NOT ALL EARTHLY ENTITIES HAVE CORRESPONDING IDEAS. In conclusion, the accidental composites in which Intelligence does not share and which are formed by a fortuitous complex of sense-objects, have no ideas corresponding to them in the intelligible world. Things that proceed from decay are produced only because the Soul is unable to produce anything better in this case; otherwise she would have rather produced some object more agreeing with nature; she therefore produces what she can. EVEN THE ARTS ARE DEPENDENT ON THE SOUL. All the arts concerned with things natural to man are contained within the ideas of Man himself. The Art that is universal is prior to the other arts; but Art is posterior to the Soul herself, or rather, to the life that is in Intelligence before becoming soul, and which, on becoming soul, deserves to be called the Soul herself.
