Note 72 — LECTURE VI SUBCONSCIOUS PROCESSES

I forbear to enter into the question of the nature of consciousness and matter. In the last analysis, matter and mind probably are to be identified as different manifestations of one and the same principle—the doctrine of monism—call it psychical, spiritual, or material, or energy, as you like, according to your fondness for names. For our purpose it is not necessary to touch this philosophical problem as we are dealing only with specific biological experiences.
