 Strauss’s distinction between Judaism and Islam, on the one hand, and Christianity, on the other, is decisive for understanding his conception of the relation between Jerusalem and Athens as well as for appreciating his conception of the theologico-political problem, as a diagnosis of modernity’s philosophical, theological, and political ills. On an epistemological level, philosophy may well have good arguments to make in response to revelation. Strauss explicitly criticizes what he regards as Rosenzweig’s and Karl Barth’s decisionist conception of revelation, i.e. revelation as a leap of faith, which, he maintains, holds no promise of rationalism. From an epistemological point of view, philosophy understood as a way of life, concerned with problems and unconvinced of promises of absolute solutions, will appear more rational to potential philosophers.
