We cannot think of soul being diffused as a quality is, say sweetness or colour, for while these are actual states of the masses affected so that they show that quality at every point, none of them has an independent existence; they are attributes of body and known only as in body; such quality is necessarily of a definite extension. Further, the colour at any point is independent of that at any other; no doubt the Form, White, is the same all over, but there is not arithmetical identity; in soul there is; it is one soul in foot and in hand, as the facts of perception show. And yet in the case of qualities the one is observably distributed part for part; in the soul the identity is undistributed; what we sometimes call distribution is simply omnipresence.
Obviously, we must take hold of the question from the very beginning in the hope of finding some clear and convincing theory as to how soul, immaterial and without magnitude, can be thus broad-spread, whether before material masses exist or as enveloping them. Of course, should it appear that this omnipresence may occur apart from material things, there is no difficulty in accepting its occurrence within the material.
