MOST OF THE ARTS ACHIEVE THEIR OWN ENDS.
Architecture and the fine arts, fulfil themselves in such an object. Medicine, agriculture and similar professions, however, are auxiliary arts, and obey the laws of nature, assisting their efficient production so as to make them as natural as possible. As to rhetoric, music, and other arts of refinement, which serve the education of souls in improving or degrading men, it remains an open question how many there are of them, and what power they possess. In all these things, we will have to examine what may be of use to us for the questions we are treating, and we will have to discover the cause of the facts, as far as possible.
ABSURDITY OF PTOLEMEAN ASTROLOGY.
It is evident that the revolution of the stars exercises an influence first by disposing them in different arrangement; then the things contained within its spheres; then terrestrial beings, not only in body, but in soul; further, each part of the heavens exercises influence on terrestrial and inferior things. We shall indeed inquire whether the lower things in turn exercise some influence on the superior ones. For the present, however, granting that the facts admitted by all, or at least a majority, are what they seem to be, we shall have to try to explain how they are produced, by following them up to their origins. We must indeed not say that all things are caused exclusively by heat or cold, with possibly the other qualities named the "primary qualities of the elements," or with those that derive from their mixture[157]; neither should we assert that the sun produces everything by the heat, or some other star (like Saturn), by cold. For indeed what would cold amount to in the heavens, which are a fiery body, or in fire, which has no humidity? Moreover, in this manner it would be impossible to recognize the difference of the stars. Then there are many facts that could not be traced to their influence. If the influence of the stars is to be made to account for the differences of human character, which are supposed to correspond to mixtures of corporeal elements, producing a temperament in which there is an excess of cold or heat, to which such causes would one trace hate, envy, and malice? Granting even that this were possible, how would one then by the same causes explain good and bad fortune, poverty and wealth, nobility of fathers and children, and the discovery of treasures? A thousand facts equally as foreign to the influence exercised by the physical qualities of the elements on the bodies or souls of animals, could be cited.
NO CRIMES SHOULD BE ATTRIBUTED TO THE INFLUENCE OF SUBLUNARY DIVINITIES.
Neither should the things which happen to sublunary beings be attributed to either a voluntary decision, or to deliberations of the universe, or the stars. It is not permissible to imagine that the divinities sway events in a manner such that some should become thieves, others should enslave their fellow-beings, or capture cities, or commit sacrilege in temples, or be cowards, effeminate in their conduct, or infamous in their morals. To favor such crimes would be unworthy of men of the most commonplace virtue, let alone divinities. Besides, what beings would be likely to busy themselves favoring vices and outrages from which they were not to reap any advantage?
HAVING CONFUTED ASTROLOGY AND DEVILTRY, WORLD INFLUENCE IS ATTRIBUTED TO THE WORLD-SOUL.
32. Since the influence exteriorly exercised by the heavens on us, on animals, and on human affairs generally has been excluded from physical causes (of astrology) and from voluntary decisions of divinities, it remains for us to find some cause to which it may reasonably be attributed. First, we will have to admit that this universe is a single living being, which contains within its own organism all living beings; and that it contains a single Soul, which is communicated to all its parts; namely, to all beings that form part of the universe. Now every being that is contained in the sense-world is a part of the universe. First, and unrestrictedly, it is a part of the universe by its body. Then, it is again part of the universe by its soul, but only so far as it participates (in the natural and vegetative power) of the universal Soul. The beings which only participate in (the natural and vegetative power) of the universal Soul are completely parts of the universe. Those who participate in another soul (the superior power of the universal Soul), are not completely parts of the universe (because they are independent by their rational souls); but they experience passions by the actions of the other beings, as far as they have something of the universe (so far as by their irrational souls, they participate in the natural and vegetative power of the universe), and in the proportion in which they possess some part of the universe. This universe is therefore a single living being that is self-sympathetic. The parts that seem distant are not any the less near, as, in each animal, the horns, nails, fingers, the organs at distance from each other, feel, in spite of the interval which separates them, the affection experienced by any other one of them. In fact, as soon as the parts are similar, even when they are separated by an interval instead of being placed by each others' side, they sympathize by virtue of this their similarity, and the action of the distant one is felt by all the others. Now in this universe which is a single living being, and which forms a single organism, there is nothing distant enough in place not to be near because of the nature of this being whose unity makes it self-sympathetic. When the suffering being resembles the acting one, it experiences a passion conformable to its nature; when on the contrary it differs, it experiences a passion that is foreign to its nature, and painful. It is therefore not surprising that though the universe be single, one of its parts can exert on another a harmful influence, since it often happens to ourselves that one of our parts wounds another by its action; as for instance, that the bile, setting anger in motion, should crush and tear some other part of the body. Now something analogous to this bile which excites anger, and to other parts that form the human body, is discovered in the universe. Even in plants there are certain things which form obstacles to others, and even destroy them. Now the world forms not only a single animal, but also a plurality of animals; each of them, as far as it has a share in the singleness of the universe, is preserved thereby; but, in so far as this animal enters into the multiplicity of some other animal, he can wound it, or be wounded by it, make use of it, or feed on it, because it differs from itself as much as it resembles itself; because the natural desire of self-preservation leads us to appropriate what is suitable to itself, and in its own interest to destroy what is contrary thereto. Finally, each being, fulfilling its part in the universe, is useful to those that can profit by its action, and wounds or destroys those who cannot support it; thus plants are scorched by the passage of fire, and the little animals are dragged along or trampled by the greater. This generation and this corruption, this betterment and deterioration of things render easy and natural the life of the universe considered as a single living being. Indeed, it would not otherwise have been possible that the particular beings it contains should have lived as if they were alone, should possess their ends in themselves, and should live only for themselves; since they are only parts, they must, as such, concur in the ends of the whole of which they are parts; and, so far as they are different, they could not each preserve its own life, because they are contained in the unity of the universal life; neither could they entirely remain in the same state, because the universe must possess permanence, and because of the universe, permanence consists in ever remaining in motion.
