Jonathan Cohen brings together the views of three of the greatest scholar-thinkers in the area of Jewish philosophy of the twentieth century, Harry Austryn Wolfson (1887-1974), Julius Guttmann (1880-1950), and Leo Strauss (1899-1973). Each thinker’s construction of Jewish philosophy is presented through individual definitions of Judaism and philosophy, understandings of its historical development, and analyses of the canons used in interpretations of Jewish philosophical texts.
