Page "belles_lettres" Paragraph 359

First, we realize that a pure specialist does not exist.

But, for practical purposes, we have people who can be considered as such.

For example, there are persons who are in physical science, in the field of mineralogy, trained in crystallography, who use only X-rays, applying only the powder technique of X-ray diffraction, to clay minerals only, and who have spent the last fifteen years concentrating on the montmorillonites ; ;

or persons in the social sciences in the field of anthropology, studying the lung capacity of seven Andean Indians.

So we see that a specialist is a man who knows more and more about less and less as he develops, as contrasted to the generalist, who knows less and less about more and more.
