The Epistemology of Rhetoric

Erik Bengtson’s The Epistemology of Rhetoric is an insightful exploration into the intersection of rhetoric and knowledge, particularly in the context of contemporary post-truth society. The book argues that the discipline of rhetorical studies must reassess its epistemological foundations to remain relevant and to address the challenges posed by post-truth rhetoric​. Bengtson navigates through historical and contemporary rhetorical theories, drawing heavily on classical Greek texts, particularly the works of Plato and Aristotle, to build a framework for understanding rhetoric as a form of argumentation that supports knowledge claims.

A key strength of the book is its dual focus on both the practice of rhetoric and its academic study, emphasizing that both are deeply embedded in knowledge formation and use​. Bengtson critiques postmodern rhetorical theories for their tendency to question truth claims without providing mechanisms for substantiating knowledge, advocating instead for a more constructive approach that recognizes the value of rhetorical argumentation in knowledge production​.

The author also engages with the historical tension between doxa (opinion) and episteme (knowledge), proposing that contemporary rhetorical studies should embrace doxa as a legitimate form of knowledge, thereby challenging the traditional Platonic hierarchy that privileges episteme over doxa​. This perspective is particularly relevant in today’s landscape where the lines between opinion and fact are often blurred.

However, the book is not without its shortcomings. While Bengtson offers a thorough critique of existing rhetorical theories, some readers may find the text dense and challenging due to its extensive engagement with philosophical concepts and historical analysis. Additionally, the author’s attempt to bridge classical rhetoric with modern epistemological concerns, though commendable, occasionally feels stretched.

Overall, The Epistemology of Rhetoric is a valuable contribution to rhetorical studies, providing a well-argued case for the epistemological significance of rhetoric in both theory and practice. It is particularly recommended for scholars interested in the philosophical underpinnings of rhetoric, the evolution of rhetorical theory, and its application in contemporary discourse.
