This article argues that both courage and reason are necessary aspects of moral action. It begins by examining Plato’s changing conceptions of these two virtues, and, in particular, the settled view he arrives at in The Statesman. Sloterdijk’s recent attempt in his book advocating rage to appropriate this dialogue in order to criticize Habermas is then considered. I suggest, by interpreting various claims by these two authors, that neither understands that both reason and courage have essential roles in moral action. (...) Additional support for this conclusion is found, not just in Plato’s late work, but in a ‘third generation’ reworking of critical theory recently developed by Menke. (shrink)
