“Revision of character will be a much more tangible and scientific thing when the physiology of psychology becomes more than a controverted conjecture. There has been no attempt, no methodical attempt, to amend character thru physiological and neural violence; and about all we know about the possibilities of such a surgery consists of glimpses caught on occasions of casualty. We do know, however, that neural changes appear promptly and invariably in consciousness, and that there is every reason to suspect perfect parallelism between the neural and psychic processes. This unfailing attendance and dependence of mind on physical phenomena, and the superior tangibility of matter over consciousness, assure the prophet that an accomplished and sensitized attention is the all-essential to the achievement of psychical amendment by neural and physiological alteration. In the New Age which we prevision and approach, among the marvels to amaze our clumsy contemplations will be the miracles of cerebral surgery, the physics of the humors, the science of the physiology of consciousness.”
