In a word, generation, as I have said, proceeding from two causes, the chiefest and most ancient poets and divines have stuck only to the first and most excellent of these, having on all occasions these known words in their mouths, Jove, the beginning, middle, source of all; but as to the necessary and natural causes, they concern not themselves with them. Whereas their successors, who were for that reason called natural philosophers, took a different course; for they, forsaking this admirable and divine principle, ascribe all matter and the passions of it to the motions, mutations, and mixtures of its parts. So that both of these are defective in their methods, because they omit, through ignorance or design, the one the efficient, the others the material cause. Whereas he that first pointed at both causes, and manifestly joined with the reason, which freely operateth and moveth, the matter, which necessarily is obedient and passive, does defend both himself and us from all calumny and censure. For we do not deprive divination either of God or of reason; seeing we allow it for its subject the soul of man, and for its instrument an enthusiastic exhalation. For first, the earth, out of which exhalations are generated, and then the sun, which in and upon the earth works all the infinite possibilities of mixture and alteration, are. in the divinity of our forefathers, esteemed Gods. And hereunto if we add the Daemons as superintendents and guardians of this temperature, as of a harmony and consort, who in due time slacken or stretch the virtue of this exhalation, sometimes taking from it the too great activity which it has to torment the soul and transport it beyond itself, and mingling with it a virtue of moving, without causing pain to those that are possessed with it; in all this it seems to me that we do nothing that can look strange or impossible or unagreeable to reason.
