VIII. Man's First Ancestors

We now find the physical human ancestor in possession of two principles: one being the physical body, which is subject to the chemical and physical laws of the world surrounding it; and the second, the sum total of the organs directly controlled by the individual life-principle. In this manner a part of the activity of the soul has been liberated. No longer retaining power over the physical sheath, the soul turns this part of its activity inwards, transforming part of the body into special organs; and so begins an inner life of the body. It no longer merely participates in the vibrations from without, but begins to feel them inwardly as individual experiences. Here sensation begins. At first, the sensation somewhat resembles the sense of touch: the subject feels the movements of the outer world, the pressure caused by substances, and so on; also a sensation of heat and cold began now to be developed.
