XLVIII. ‘The whole matter, as I maintain, stands thus. All becoming has two causes, of which the most ancient theologians and poets chose to turn their attention to the stronger only, pronouncing over all things the universal refrain: _Zeus first, Zeus middle, all things are of Zeus_,[198] while they never approached the necessary or physical causes. Their successors, called physicists, did the very reverse; they [Sidenote: E] strayed away from that beautiful and divine principle, and refer everything to bodies, and pulsations, and changes, and temperaments. Hence the systems of both are deficient; they have ignored or neglected, the latter the person through whom and the agent by whom, the former the things from which and the means through which. He who first distinctly grasped both, and attached by necessary law the subject affected to the rational Maker and Mover, relieves us as well as himself from any charge of contempt or detraction. We do not make [Sidenote: F] prophecy a godless or irrational thing, when we assign to it for its matter the soul of man, and for its instrument, or harp-quill, the inspiring current and the exhalation. For, in the first place, the earth which breeds the exhalations, and the sun who gives to earth all power of temperature or of change, are reckoned Gods in the traditions of our fathers. Further, in leaving daemons to preside over and guard this temperature, as though it were a melody, to relax the strings in due course [Sidenote: 437] or to tighten, to clear away that excess of ecstasy and agitation which it causes in the worshippers, and to leave excitement a painless and harmless compound, we shall not be thought to do what is irrational or impossible. XLIX. ‘Nor can we allow that in offering the previous sacrifice, or crowning the victim, or pouring on it lustral draughts, we do anything repugnant to this view. For when the priests and holy men sacrifice the victim, and sprinkle it, and watch its movement and its trembling, they do not profess to get from it an intimation of anything but the one fact that the God is giving answers. For the thing offered in sacrifice must be pure both in body and in soul, and free from any injury or taint. As to body, it is not very difficult to make [Sidenote: B] out visible proof; the test of soul is to offer corn to the bulls, pease to the he-goats; an animal which refuses is reckoned out of health. For the she-goat it is cold water; a soul in a normal state cannot be apathetic and motionless under the sprinkling. For my own part, even if it be certain that trembling is a sign that the God is ready to give responses, the contrary that he [Sidenote: C] is not, I see no disastrous consequence. As I said before, every natural force produces its result better or worse according to season; if the right season is escaping us, it is to be expected that the God should signify the fact.
