 My work focuses on the history and theory of rhetoric and especially on the relation between rhetoric and philosophy, but I am also interested in rhetoric’s other dimensions: its close connection with processes of democratization, ancient and modern; its potential for serving as the core of a liberal arts curriculum; its power to inform the teaching of communication, especially the teaching of writing; its ability to describe how people reason and persuade one another in conditions of uncertainty without resorting to threats or violence; its vast resources for comprehending how poetic language works; and its ability to generate ideals for education and human development. My first book, The Rhetoric of Reason, developed a rhetorical framework for understanding reason as communication, and it used that framework to re-think the teaching of writing in colleges and universities. My latest book, Deep Rhetoric, focuses on the very idea of rhetoric, and builds a case for understanding rhetoric as a philosophical enterprise that is linked to the practical project of defeating violence and seeking wisdom by developing robust rhetorical capabilities in individuals and conditions of communicative justice in societies. In addition to my central interest in rhetoric, I am also interested in non-fiction writing about nature and especially in the different ways “nature” comes to presence in different forms of writing and through different media. Here, I have a central concern with the idea of wilderness, something I am inclined to defend. I am also interested in literary theory in a more general way and in the place of rhetoric in that larger critical enterprise. Finally, I have recently found myself reading more and more poetry, and that is surely leading somewhere. Recent Presentations2019.
