"The specialization that is required for successful operation as a college professor is often deadening to the mind that would grasp for higher culture in the modern world. There now is, as Whitehead has indicated, a celibacy of the intellect. Often the only 'generalization' the professor permits himself is the textbook he writes in the field of his work. Such serious thought as he engages in is thought within one specialty, one groove; the remainder of life is treated superficially"  (White Collar: The American Middle Classes, 1951, pp. 130-131).
