[As we have seen, God, by reducing chaos to order, made the world-animal, which contains all other animals, mortal and immortal. The immortal soul of man was created by God, the mortal by his children: the former was set in the head, the latter in the breast and thorax. Of the mortal soul there are two parts:—(1) Passion, seated between the midriff and the neck, and intended to assist reason against desire.] As I said at first, when all things were in disorder God created in each thing in relation to itself, and in all things in relation to each other, all the measures and harmonies which they could possibly receive.
