This article analyzes Heidegger's rhetoric in his most famous political address, the Rektoratsrede, which he delivered at the University of Freiburg on 27 May 1933. After I set out the political and philosophical kairos of the Rektoratsrede by drawing on Heidegger's contemporary lectures, letters, and Ponderings, in part 2 I use classical rhetorical resources and Heidegger's philosophy of temporality in Sein und Zeit (1927) to analyze the arrangement of his speech. In part 3, I examine two key National Socialist terms in the speech's climax. In part 4, I consider Heidegger's elocutio—his artful use of charged figures of speech and thought in the Rektoratsrede—in more detail. Concluding remarks reflect on the value and limits of the analysis in the context of debates about Heidegger's politics and its imbrication with his thought.
