1031. Light polarizes the Material by mere fixation or discharging of poles, and thus in a spiritual manner. So also does the light-system of the organism. It governs the organism not by mechanical power, not by mass, but by a spiritual breath or aura.
1032. The organic light-system is the Animative of the organism. In it the spirit exercises its power over the mucous mass. It is the nervous system.
LIFE OF THE NERVOUS SYSTEM.
1033. The light-polarity can bring about no other tension in the mass than that which is peculiar to it, and thus the galvanic tension, whose highest and purest phenomenon is motion. The light-system principally causes motion in the mass, like as in æther.
1034. The nervous system has, however, a life also in itself, or the internal light-polarity that is without any relation to the organic mass. This action of the nerves is called sensibility, and its phenomenon, feeling or sensation. The system of sensation is the nervous system as sun in itself; in the motor-system it is as sun in a centre of planets.
1035. The organism, like the elementary nature, is completed by four systems.
1. By the Nutrient,
2. " Digestive,
3. " Respiring, and
4. " Motive, unto which the nerves, muscles, and bones belong.
1036. It is impossible for more than these to be developed in an organism; impossible, for any thing else but what is in nature to originate therein; impossible, that any thing new be born by it. Everything in nature is only repetition of an Antecedent or something that has gone before. How could the organism be aught else, how aught else than the focus of the four elements!
