4 o 4 BIOLOGICAL PHYSICS 



internally working neural structural necessities, when we 

 consider that perhaps the greater part of cerebration, con- 

 scious and unconscious, is confined within the precincts 

 of the brain proper, beginning and ending there without 

 necessarily disturbing, to an appreciable extent, the outer 

 nervine calm, or making much, if any, impression on 

 memory. All this vast region of non-peripherally related 

 neuronal activity pertains to the constant ordinary, as well 

 as the higher intellectual and transcendental, regions of 

 man's everyday life and experience, and constitutes a 

 great portion of " the weft and the woof" of the inner 

 life fabric, and determines whether it will be perishing, or 

 lasting, as a contribution to the daily and hourly record of 

 individual effort. 



In this highest sphere of psychological activity we enter 

 in reality the region of human anatomy, where material 

 mechanism is constructed for the performance of func- 

 tions of a materio-dynamic character, the quality of which 

 can only be dimly appreciated by the exercise of those 

 inherent or innate hyper- or meta-physical human 

 qualities which more or less pervade the records of the 

 highest types of materio-dynamic philosophy and spiritual 

 insight. From this point of view it becomes evident that 

 " a whole cosmos " of human experience is confined within 

 the non-peripherally related^ or the highest cerebral centres^ 

 where the higher sensory centres, and the great motor 

 centres, are co-related with, but prohibited from entering, 

 the great mental areas, where the ego, the seat of 

 consciousness and abstract thinking and reasoning, abides, 

 protected, if not free, from friction with the external 

 world, and at liberty solitarily to cogitate, associate, and 

 perchance commingle in activity, with materio-dynamic 

 and spiritual existences on lines altogether transcendental, 

 but nevertheless appreciable by the intellect, or perhaps 

 visible to the "mind's eye," and defined more or less 

 clearly by the " exponents of things spiritual " as seen 

 in what they have handed down to us in the pages of 

 revelation, and the works of " light and leading " which 

 from time to time have been " given to the world " by 

 the highest types of humanity. The mind of man has 

 thus an indefinitely large cerebral materio-dynamic field
