APPLICATIONS AND POSSIBILITIES 265 



accurate examination, was possible, in the matter of classifica- 

 tion for vocation, without the insight into the physiology of the 

 candidate that the analysis of his endocrine formula will pro- 

 vide. 



One need not dilate upon the value of such an examination. 

 Civilization has not yet learned how to pick its personnel. And 

 so artists and scientists, philosophers and politicians, financiers 

 and religious leaders, arise and survive by the operation of the 

 laws of probabilities and chances, rather than by any intelligent 

 selection and cultivation of material. The case, indeed, is simply 

 a subdivision of the vast subject: haphazard muddle in the con- 

 duct of life. A cry has been raised for the superman, and a cry 

 has been raised for a method of anthropometry. For the lack of 

 these two, it has been said, all governments have been doomed 

 to defeat. The study of the endocrines will by no means supply 

 a panacea. But as it will furnish a means of approach to the 

 determination of how men and women are built, and why they 

 are built differently, no one can gainsay the tremendous advan- 

 tages to the nation that will proceed to classify its population 

 accordingly, and know its strength and weakness in terms of the 

 actual generators of success and failure. 



Suggestions have been offered in the preceding pages of con- 

 crete applications of endocrine knowledge to the understanding 

 of behaviour, of the genius and commonplace, criminal and Puri- 

 tan. And in the chapter on historic personages, we tracked some 

 of the story in detail. This vein when explored will quarry un- 

 told riches. It has been observed that financiers of mark, like 

 great musicians, are special pituitary types. Also that the finan- 

 ciers are voracious meat eaters and the musicians inordinately 

 fond of sweets. Differences in anterior and posterior predomi- 

 nances might account for this. That we are playing here with 

 no phantasy is proven by the fact that we can effect changes of 

 tastes as well as of intellectual direction by^ appropriate feeding 

 of various glandular extracts. Just as much, indeed, as we can 

 influence sex susceptibility, and the reaction to sex stimulation, 

 by the artificial introduction from without of the proper hor- 

 mones.
