About as eminent an academic philosopher as they come these days, Robert B. Pippin made his reputation with a sequence of brilliant studies rehabilitating the great names of German Idealism – Immanuel Kant, G.W.F. Hegel – for a (mainly) baby boomer American audience. In the wake of the path-breaking interventions of Wilfrid Sellars and Richard Rorty, Pippin, alongside such colleagues as Terry Pinkard, Robert Brandom, and John McDowell, has argued for a version of the essentially dialogic nature of all philosophy, which seeks to bring together metalogical ratiocinations and nitty-gritty semantic theories with reflections on the diversity of social interactions.
