Kenneth Burke's concept of communication spans multiple disciplines, ranging from rhetoric to literary theory to sociology to philosophy, but is focused on bridging multiple and competing points of view. Widely regarded as the most important rhetorician of the 20th century, Burke is equally a dialectician: a Socratic midwife who seeks to unsettle and then bridge partial and partisan perspectives. He captures these partial perspectives in creative concepts such as perspective by incongruity, frames of acceptance and rejection, dramatism, the pentad, the human barnyard, the parliamentary wrangle, and terministic screens and seeks to bridge them via identification—the concept for which he is most famous; the human drama of the unending conversation; and dialectical processes of transcendence.
