Was Wittgenstein Jewish?

Did Ludwig Wittgenstein consider himself a Jew? Should we? Wittgenstein repeatedly wrote about Jews and Judaism in the 1930s (Wittgenstein 1980/1998, 1997) and the biographical studies of Wittgenstein by Brian McGuinness (1988), Ray Monk (1990), and Béla Szabados (1992, 1995, 1997, 1999) make it clear that this writing about Jewishness was a way in which he thought about the kind of person he was and the nature of his philosophical work. On the other hand, many philosophers regard Wittgenstein's thoughts about the Jews as relatively unimportant. Many studies of Wittgenstein's philosophy as a whole do not even mention the matter, and those that do usually give it little attention. For instance, Joachim Schulte recognizes that “Jewishness was an important theme forWittgenstein” (1992, 16–17) but says very little more, except that the available evidence makes precise statements difficult. Rudolf Haller's approach in his paper, “What do Wittgenstein and Weininger have in Common?,” is probably more representative of the received wisdom among Wittgenstein experts.
