Abstract

In contemporary philosophical thought, Leo Strauss is associated with the rediscovery of ancient political philosophy against modern political philosophy. The rediscovery of ancient political philosophy is the rediscovery of classical rationalism or “moderate Enlightenment” against modern rationalism or “radical Enlightenment” and can be understood as recapturing the “the question of man’s right life” and “the question of the right order of society”. This article would like to show that it was his study of medieval Islamic and Jewish texts that enabled Strauss to rediscover the classical rationalism. Also, in this article we would like to argue that although the opposition between Athens and Jerusalem, Reason and Revelation embodies two irreconcilable alternatives or a way of life in his thought, this opposition should be only examined with references to claims about radical rationalism of modern philosophy. In this case, we would like to argue that there can be seen a commonality between these “opponents”, i.e., Athens and Jerusalem, Reason and Revelation in terms of both their attitudes towards morality and their approaches to the relationship between philosophy and society.
