CHAPTER X 

 THE TYPES OF PERSONALITY 



The Endocrine Personality 



If a single gland can dominate the life history of an individual 

 it becomes possible to speak of endocrine types, the result of the 

 endocrine analysis of the individual. Studying endocrine traits of 

 physique, life reactions, disease tendencies, hereditary history 

 and blood chemistry, one may gain an insight into the composi- 

 tion or constitution of an individual. The endocrine type of an 

 individual is a summary of these, his behaviour in the past, and 

 is also a prediction of his reactions in the future, much as a 

 chemical formula outlines what we believe to be the skeleton 

 of a compound substance as deducible from its properties under 

 varying conditions. Only, admittedly, as yet the endocrine 

 label is but roughly qualitative and most crudely quantitative, 

 whereas the chemical formula is the essence of the exact. 



However, the fact remains that though we are only upon the 

 first rungs of the ladder, we are upon the ladder. The horizon 

 undoubtedly broadens. We possess a new way of looking upon 

 humanity, a fresh transforming light upon those strange phe- 

 ourselves. Of the ugly achievements of that dreadful 

 century, the nineteenth, the most illuminating was the discovery 

 If as the ape-parvenu. Yes, we are all animals now, it said 

 If, and set its teeth in the cut-throat game of survival. 

 But there was no understanding in that evil motto of a dis- 

 illusic irt. The ape-pan tely lonely and 



. has still to understand himself. 

 Let us \» ! we can. There is perhaps a certain presump- 



tion in the phrase, the endoerh mbitious, and per-
