Recently I looked at my copy of Buber’s I and Thou translated by Walter Kaufmann which had been sitting on my shelf unread for decades; somewhere Leibowitz had referred to Buber’s philosophy as “ladies' philosophy“ so I’d dismissed it. I knew of Kaufmann from reading Nietzsche, and considered (again) the former’s extraordinary accomplishment in bringing that philosopher’s work to the English-speaking world. After reading his introduction to I and Thou, I immediately turned to Kaufmann’s The Faith of a Heretic, where he tells us that at age 12 he converted from his parents’ chosen religion, Protestantism, to the Judaism of his birth. If converting to Judaism in 1930s Germany sounds heroic, consider that Martin Buber’s wife, Paula, Catholic by birth, converted to Judaism in 1904 (overseen by a Liberal rabbi) and in 1934 made the remarkable choice of undergoing conversion again, this time by an Orthodox court in an increasingly perilous Germany. In Stanley Corngold’s fine intellectual biography of Kaufmann, Walter Kaufmann: Philosopher, Humanist, Heretic, I learned that in The Faith of a Heretic, published just a year after Critique of Religion and Philosophy, Kaufmann criticizes Christianity for prizing personal salvation above all else. He is dismissive of the concept ”Judeo-Christian” because he views the younger of the two religions more as a product of Greek philosophical thought combined with paganism than as a later iteration of Hebraic Prophetic thought.
