Abstract
Defining a rhetoric as a social invention arising out of a particular time, place, and set of circumstances, Berlin notes that no rhetoricnot Plato s or Aristotle s or Quintilian s or Perelman sis permanent. At any given time several rhetorics vie for supremacy, with each attracting adherents representing various views of reality expressed through a rhetoric.Traditionally rhetoric has been seen as based on four interacting elements: reality, writer or speaker, audience, and language. As emphasis shifts from one element to another, or as the interaction between elements changes, or as the definitions of the elements change, rhetoric changes. This alters prevailing views on such important questions as what is appearance, what is reality.In this interpretive study Berlin classifies the three 19th-century rhetorics as classical, psychological-epistemological, and romantic, a uniquely American development growing out of the transcendental movement. In each case studying the rhetoric provides insight into society and the beliefs of the people.
