"The professor of social science, for example, is not very likely to have as balanced an intellect as a top-flight journalist, and it is usually considered poor taste, inside the academies, to write a book outside of one's own field"  (White Collar: The American Middle Classes, 1951, p. 131).

"The professionalization of knowledge has thus narrowed the grasp of the individual professor; the means of his success further this trend; and in the social studies and humanities, the attempt to imitate exact science narrows the mind to microscopic fields of inquiry, rather than expanding it to embrace man and society as a whole"  (White Collar: The American Middle Classes, 1951, p. 131).
