successes of a man's everyday
life. And no doubt there is a relation. Sublimation plays its part in
the explanation of vocational idiosyncrasies. The fact, however, that
perfect success in sex may occur with absolute failure in the career,
however, splits the problem for good into its realities: a physiologic
aspect as well as a psychologic.

So, as school education will have to take serious account of endocrine
anomalies and possibilities, will the institution which selects and
trains for a career. Vocational misfits have aroused the ardor of our
efficiency experts. And again, the sweeping psychological attack has
beaten its head against the stonewall of ignorance of constitutional
predispositions and tendencies of material. The attempt to erect
psychologic types for vocational selections could never make much
headway because it could only flounder in a swamp of metaphors,
product of the vices of its methods. Not that anyone would wish to
discard at all the psychologic mode of approach. But no science, in
the sense of accurate examination, was possible, in the matter of
classification for vocation, without the insight into the physiology
of the candidate that the analysis of his endocrine formula will
provide.

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 conduct 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
advantages 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 concrete
applications of endocrine knowledge to the understanding of behaviour,
