From the beginning, rhetoric has been a productive and practical art aimed at preparing citizens to participate in communal life. Possibilities for this participation are continually evolving in light of cultural and technological changes. The Available Means of Persuasion: Mapping a Theory and Pedagogy of Multimodal Public Rhetoric explores the ways that public rhetoric has changed due to emerging technologies that enable us to produce, reproduce, and distribute compositions that integrate visual, aural, and alphabetic elements. David M. Sheridan, Jim Ridolfo, and Anthony J. Michel argue that to exploit such options fully, rhetorical theory and pedagogy need to be reconfigured.
