150 Human Personality. 



personality. A glance at the . organic mechanism is suffi- 

 cient to show that these cells and groups of cells can 

 have but a secondary, or reflex representation ; a faint 

 twice-reflected sense, like earth-shine on the unlighted 

 segment of the moon. For muscle and gland cells form 

 groups by themselves, not interlaced with the neurons and 

 having no interlacing processes, being only reported, if we 

 may use that word in this sense, to the neuron group by 

 means of immensely long filaments which the latter have 

 sent forth. In fact, all those vast groups of cells in 

 muscle, bone, and gland are, so far as the human person- 

 ality is concerned, but so many outlying, alien provinces 

 of an empire, controlled and stimulated to action from the 

 central capital, but only reflexly and faintly symbiotic 

 with it. 



The manner in which personality — intellect and mind 



— fell to the lot and became the task of the neuron group, 

 is now apparent and can be demonstrated. A trace of it 

 appears even in the zoaria of polyzoa. Something like an 

 incipient nervous system exists in christatella mucedo and 

 in kinetoskias where a colony of unicells is seen to act as 

 an individual, by transmission of impulses from cell to 

 cell to insure simultaneous action to a certain end on the 

 part of all the cells. The same is observed in the volvo- 

 cine colonies. This is the first step to a nervous system, 



— the transmission of a directive impulse from cell to cell. 

 At this early stage of differentiation of function, any
