of existence, is the inherent attribute of matter. In the historical evolution of the natural sciences, the forms of motion governing non-living nature has advanced in propor. tion with the progress of Mechanics, Physics and Chemistry, Hence the Causa finalis is matter and its inherent motion. 1 From matter develop various kinds of physiological mechanisms. Changes in matter are always arising out of the situation caused by the self-development of a given situation. All nature is made up of processes. The living man, the corpse, death, are processes, 9 It is an eternal cycle in which matter moves, a cycle that certainly only completes its orbit in periods of time. Eternal cycle of matter in motion is the ultimate conclusion of science. 3 Mind is the mere effect of matter At one level matter is mindless, at the next, it is minded. Master itself thinks when organised in a brain. Mind is a characteristic of matter at a high stage of its development. There is unity and identity of matter and mind.
So far science is quite correct. Science lands itself in difficulty when it deals with life. Life is the mode of existence of albuminous substances. The organic cxchange of matter is the most general and most characteristic phenomenon of life. Non-living bodies change, decompose and enter into combinations in the course of natural processes; but in doing this they cease to be what they were. But what with non-living bodies is the cause of destruction, with albumen is the fundamental condition of existence. When the uniterrupted metamorphosis of its constituents, the canstant alternation of nutrition and excretion, no longer takes place in an albuminous body itself comes to an end, it decomposes ; that is, dies. Life, the mode of existence of albuminous substance, therefore, consists primarily in the fact that at each moment it is itself and at the same time something 1.
