194 THE GLANDS REGULATING PERSONALITY 



the endocrine part of it, that is the latent power of each gland 

 to secrete at a minimum or a maximum, and the balance between 

 them. 



Education of the Vegetative System 



3. Training or education involves, beside other effects, a 

 training of the endocrines, and hence of the entire vegetative 

 apparatus, to respond in a particular way to a particular stimu- 

 lus. Experience is like the introduction of new push-buttons, 

 levers, and wheels into the mechanism. All learning which calls 

 out or arrests the functioning of an instinct, must, from what we 

 have learned of the chemical dynamics of instincts as reactions 

 between hormones, nerves and viscera, affect the vegetative sys- 

 tem. When there is a conflict between two or more instincts, 

 between pressures of energy flowing in different directions, there 

 may be compromise and normality, or a grinding of the gears and 

 abnormality. 



Where does the brain come in, in all this? As the servant of 

 the vegetative apparatus. To call it the master tissue is mani- 

 festly absurd, when it can only be the diplomatic constitutional 

 monarch of the system. It can, in fact, act only as the great 

 central station for associative memory, as only one of the factors 

 implicated in education. 



The most powerful educative agents of the vegetative appa- 

 ratus of a human being are the other humans around him. And 

 they comprise the most powerful of the ts of 



education, for better, for worse. The training and education of 

 ndocrine-ve<:et alive system is the b:t 1 social rules 



rn. Convention, Law, Conscience). An unresolved 

 discord, a continued conflict among the parts of the \ 



system, in spite of such education, is the foundation of the un- 

 happiness of the acute or chronic misfits and maladjusted, the 

 rotic and the psychotic.
