HOW SOULS COME TO DESCEND.
13. What is called inevitable necessity and divine justice consists in the sway of nature which causes each soul to proceed in an orderly manner into the bodily image which has become the object of her affection, and of her predominating disposition. Consequently the soul, by her form, entirely approaches the object towards which her interior disposition bears her. Thus she is led and introduced where she is to go; not that she is forced to descend at any particular moment into any particular body; but, at a fixed moment, she descends as it were spontaneously where she ought to enter. Each (soul) has her own hour. When this hour arrives, the soul descends as if a herald was calling her, and she penetrates into the body prepared to receive her, as if she had been mastered and set in motion by forces and powerful attractions exerted by magic. Similarly in an animal, nature administers all the organs, solves or beets everything in its own time, grows the beard or the horns, gives special inclinations and powers to the being, whenever they become necessary. Similarly, in plants, (nature) produces flowers or fruits at the proper season. The descent of souls into the bodies is neither voluntary nor forced; it is not voluntary, since it is not chosen or consented to by souls. It is not compulsory, in the sense that the latter obey only a natural impulsion, just as one might be led to marriage, or to the accomplishment of various honest actions, rather by instinct than by reasoning. Nevertheless, there is always something fatal for each soul. One accomplishes her destiny at some one moment; the other soul at some other moment. Likewise, the intelligence that is superior to the world also has something fatal in its existence, since itself has its own destiny, which is to dwell in the intelligible world, and to make its light radiate therefrom. Thus individuals come here below by virtue of the common law to which they are subjected. Each one, indeed, bears within himself this common law, a law which does not derive its power from outside, but which depends on the nature of those who are subject to it, because it is innate in them. Consequently all voluntarily carry out its decrees at the predestined time, because this law impels them to their goal; and because, deriving its force from those whom it commands, it presses and stimulates them and inspires them with the desire to go whither their interior vocation calls them.
