Even in the simplest human societies, linguistic competence is the price of admission. In our own modern society, no hermit, no fugitive, can escape the range of our communication technology. From writing to printing to telegraphy to radio to television the pace of that technology has steadily accelerated.
Wise men knew their importance long ago, but only in the twentieth century have we begun to subject communication and language to the kind of scholarly and scientific analysis their importance merits. Today the study of communication and language flourishes as never before.

Because communication and language are so ubiquitous and have been studied from so many points of view for so many di
