The spirits of those two provinces are completely separated, in a miraculous way, for the sake of the spiritual - when nevertheless they should make one - just as, in man also, the cerebellum is separated from the cerebrum; but still they communicate, both in general, as in the medulla oblongata, and in the single fibers and nerves; so that there is not a fiber which has not something from the cerebrum and from the cerebellum, thus, from the voluntary and from the involuntary part; unless which were the case, man would perish in a moment. The voluntary part is miraculously ruled by means of the involuntary.
