THE SOUL IS SAID TO BE IN THE BODY BECAUSE THE BODY ALONE IS VISIBLE.
All men say that the soul is in the body, however, because the soul is not visible, while the body is. Observing the body, and judging that it is animated because it moves and feels, we say that it has a soul, and we are thereby led to suppose that the soul is in the body. But if we could see and feel the soul, and if we could realize that she surrounds the whole body by the life she possesses, and that she extends around it equally on all sides till the extremities, we would say that the soul is in no way in the body, but that on the contrary the accessory is within its principle, the contained within the container, what flows within the immovable.
