In this essay, we trace Perelman and Olbrechts-Tyteca‟s turn from logical positivism and the accepted belief that reason‟s domain was the vita contemplativa to rhetoric and its use as a reason designed for the vita activa. Our effort to tell the story of their rhetorical turn, which took place between 1944 and 1950, is informed by an account of the context in which they considered questions of reason, responsibility, and action in the wake of World War II.en-USPerelman, ChaimOlbrechts-Tyteca, LucieArticle
