HUMAN PSYCHOLOGY.

denies the existence of spirit ; Scepticism that either doubts or 

 denies the existence of both : and Kealism that affirms the existence 

 of both spirit and matter. 



And this history is the history of man's experience in the great 

 realm of thought as to the nature of the mind, what is it ? what 

 can it do ? and what can't it do ? And the answers given enable 

 us to say what the answerer's psychology will be before he utters 

 another word. At least I believe so. 



(4) The one class of phenomena implies the substance we call 

 matter, the other class the substance we call spirit. 



(5) Anabolic and katabolic are merely stages in the process of 

 metabolism whereby the body is built up and maintained. They 

 are vegetative processes. 



As I said before, the body is the seat of the senses. These are 

 the organs of world-consciousness. Hence my use of the term 

 organic. This body has to be built up, maintained, etc. Hence 

 my use of the term vegetative. Of course there must be organs by 

 which these processes are carried on, but these are merely secondary 

 to the first. Life governs all, but without motion our senses would 

 be idle. Light, heat, sound, magnetism, and so on, are but modes 

 of motion. Light is etheric movement, but it is material, for, as 

 Einstein has shown, it is bent by the force of gravity. Motion is 

 change of position. Change in position of what ? Matter. " Spirit 

 (or force) " Dr. Schofield says, but not I. To say spirit is identical 

 with force is simply materialism. 



(6) I do not say that mental processes are only possible through 

 the brain." 



But in man's case the seat of consciousness is in the brain, and 

 injury to the brain often upsets his mental processes. The quotation 

 is meant to show that there is a great gulf between modifications of 

 matter and mental states. 



To knov) all is to forgive all I The knowledge of my imperfections 

 may incline you to the forgiveness of the shortcomings in my attempt 

 at the elucidation of some of the difficulties that have puzzled the 

 students of psychology from the earliest (of whom we have any 

 records) down through the ages unto this present day.
