Chapter III

Through the mechanical theory of heat and the wave theory of light and of electric phenomena, I was impelled to a study of theories of cognition. At that time the external physical world was conceived as motion-events in matter. The sensations appeared to be only subjective experiences, as the effects of pure motion-events upon the senses of men. Out there in space occurred the motion-events in matter; if these events affected the human heat-sense, man experienced the sensation of heat. There are outside of man wave-events in the ether; if these affect the optic nerve, light and colour sensations are generated within man.
