From “On Intellectual Craftsmanship,” an essay from The Sociological Imagination that I love:
In many academic circles today anyone who tries to write in a widely intelligible manner is liable to be condemned as a ‘mere literary man’ or, worse still, ‘a mere journalist.’ Perhaps you have already learned that these phrases, as commonly use, only indicate the spurious inference: superficial because readable. The academic man in America is trying to carry on a serious intellectual life in a social context that often seems quite set against it. His prestige must make up for many of the dominant values he has sacrificed by choosing an academic career. His claims for prestige readily become tied to his self-image as a ‘scientist.’… It is this situation, I think, that is often at the bottom of the elaborate vocabulary and involved manner of speaking and writing. It is less difficult to learn this manner than not. It has become a convention–those who do not use it are subject to moral disapproval.
…Desire for status is one reason why academic men slip so readily into unintelligibility. And that, in turn, is one reason why they do not have the status they desire. A truly vicious circle–but one out of which any scholar can easily break.
