The Rhetoric of Expertise conceptualizes expertise as a function of persuasion; specifically, it explores four different contexts-politics, history, medicine, and information-in which expertise is rhetorically constructed in a tension between two competing alternatives. In this book, E. Johanna Hartelius provides a rhetorical theory and vocabulary for understanding expertise. This enriches such perennial concerns in rhetorical studies as credibility, artistic and inartistic means of persuasion, the discursive nature of knowledge, and the rhetoric of power and authority.
