We see consequently that the cells may do without the soul in such functions as are not related to the exterior world comprehensible through our senses. Here they need the guidance of a higher, more developed intelligence. In the outside world with its more complicated relations, the soul is to the cells very nearly what we mean by the word _Providence_. The soul performs, in the interest of the cells, such a higher, regulating and guiding function. The organism, then, is divided into two sections, separated by a sharply defined boundary. As independent and autocratic as the cells are in one of them, is the soul in the other. This bisection in two widely separated spheres is in itself remarkable, but may be explained, if we remember that the organism is an individual composed of lower individuals. As different as these classes of individuals are in their nature and faculties, equally incongruous are also the realms in which they dwell. The cells move in the atomic and molecular world. To them the molecules and atoms appear with a clearness comparable to the plainness with which the exterior world reveals itself to us. It is natural then that the cells attend to the vegetative functions of the organism which just fall within their sphere of life, a sphere of which the soul can obtain knowledge only indirectly by way of deductions. Equally obvious it is that only the soul can employ the organs of the body, the functions of which fall within the visible world. We have now endeavored to obtain an understanding of the importance of the soul to the cells by depriving the latter of the direct influence of the former. This resulted from the removal of the brain, the organ by which the soul more directly expresses itself. But the soul is not actually removed from the body. It still remains in the whole cell-mass. The brain itself consists of cells, in which the soul is not present except as in all the other cells. The difference is only that the brain-cells are developed for the functions of thought, whereas the cells in the other organs are intended for their specific purposes. In order to remove the soul from the body we must remove the life from every cell. The soul, as we intend to show, is inseparably connected with every particular cell-individual. But in order to understand how the cells may be at once independent of, and yet intimately united with the soul, we must first know what an organism really is. Its nature and fundamental idea is the only thing that can explain this remarkable relationship. But it is just here as to the essential qualities of an organism that the conceptions are generally very dim and vague.
