(4) Life through those first elements is present from every part in the whole, and from the whole in every part. The reason is that the whole, which includes both the brain and the body, consists initially
only of fibers which issue from their first elements in the brain. It has no other beginning, as is apparent from what we have shown just above in no. 366. Consequently the whole arises from every
part. Life through those first elements is present also from the whole in every part for the reason that the whole supplies to every part its portion and requirement, and so makes it to be a part
of the whole. In a word, the whole arises from the parts, and the parts are dependent on the whole. The existence of such a reciprocal relationship and consequent conjunction is apparent from many
illustrations of it in the body. For the case in it is the same as in a city, republic or kingdom, that the whole is formed of the people who are its parts, and the parts or people are dependent on
the whole. It is the same with everything that has some structure; especially so in the human being.
