 According to Leibowitz, the central idea of Jewish monotheism is the radical transcendence of God, a view that has previously been given its starkest exposition by his philosophical hero, Maimonides. Postponing discussion of its precise logical status for Leibowitz, and provisionally accepting that “God is radically transcendent” is a cognitive statement, a rough first formulation of its meaning would be that God is an existent entity that is absolutely incomparable to any other form of reality that we can possibly encounter.
