This workshop is focused on Martin Heidegger’s most concentrated engagement with thinking about history, his 1926 summer seminar on Johann Gustav Droysen’s textbook on historical methodology (Grundriss der Historik). While Heidegger’s teacher, Heinrich Rickert, was a central figure in the late nineteenth-century German debate about what constituted historical knowledge (as opposed to natural scientific knowledge), and while history was the subject of the public lecture that marked his entry into university life in 1915 (“The Concept of Time in the Science of History”), and while history occupied a major role in Being and Time, his classic work of 1927, that 1926 seminar, which was his most direct engagement with academic history and its practice has neither been published, translated, or commented upon. Peter N. Miller (Bard Graduate Center), Jan Eike Dunkhase (a 2019 research fellow at Bard Graduate Center) and Ingo Farin (University of Tasmania) are currently producing an edition, translation, and series of essays on that seminar and its importance for Heidegger and twentieth century thought. For it turns out that among the auditors of that seminar were Paul Oskar Kristeller, later doyen of Renaissance studies in the United States, Karl Löwith, the polymathic commentator on philosophy and history in the nineteenth century, and Hans-Georg Gadamer, philosopher and theorist of hermeneutics, while the literary remains of the slightly younger Reinhart Koselleck, the most important German historian of the second half of the twentieth century, show his deep debt to Heidegger’s “philosophy of history.”
