158 ANIMAL LIFE AND SOCIAL GROWTH 



the more primitive animals with distinct heads. 

 In these higher forms, the parts of the body, the 

 viscera, the muscles, the endocrine glands acting 

 through the blood stream, co-operate in deter- 

 mining the physiological condition of brain cor- 

 tex and hence the content of awareness and the 

 nervous impulses that may result. 



Similarly within societies, as the connections 

 between the different animals composing the group 

 become more direct, as means of communication 

 either by abstract signs, words in man, or by a 

 flow of stimuli or of materials become more direct 

 and rapid, and as the region of dominance becomes 

 so developed that these impulses register rapidly, 

 even so does the social control tend to become 

 less autocratic and more democratic. 



In Amoeba and other lower animals the commu- 

 nications are through protoplasms only, which 

 have slight ability to transmit stimuli. The 

 regions of dominance are little different, and 

 then only temporarily so, from the subordinate 

 regions and a state of physiological anarchy fre- 

 quently exists, as in the sea anemones, where one 

 part of the animal's body may work in direct 

 opposition to another. This is similar to the 

 social anarchy of the more loosely organized 

 animal aggregations. At the other extreme, 

 when a body becomes so highly organized that
