 Rather than setting out his philosophy comprehensively in the form of a system based on foundational premises, Leibowitz generally wrote short articles devoted to specific topics. It is nonetheless fair to say that there is a single axis around which his philosophy of Judaism revolves and to which many of his views can ultimately be traced – the radical transcendence of God. In what follows we will begin with Leibowitz’s understanding of God’s transcendence, which will enable us to proceed to his conceptions of theology, Scripture, Jewish faith, ethics, and briefly politics, all of which ultimately wend their way back to that fundamental idea. While occasionally developments and changes in his thought will be noted, particularly in the political section, on the whole we will be dealing with his mature views since, as Hannah Kasher has argued, in the 1992 English translations to which most readers of this will have access, even the earlier essays have been translated in a manner that often reflects the later views (Kasher, 2000, 54).
