Kathleen Hall Jamieson has an enlightenment faith in “eloquentia perfecta” – faith in reason, faith in facts, faith in public debate and civil discourse. Sometimes – and especially these days – that faith might feel in short supply. But that faith took Jamieson from Marquette University, class of 1967, to the heights of political communication scholarship – authoring a library shelf of pioneering books, achieving a CV’s worth of distinguished career awards, and serving as both dean and public policy center director at the University of Pennsylvania’s Annenberg School for Communication. In episode 14 of Formative, we talk about presidential communication styles from Reagan’s televisual charm to Trump’s norm-shattering volume; the epistemological peril in discrediting expertise; and how rhetoric, at its best, can open up the humanity of an audience.
