This book on the life and work of Josef Schächter, member of the Vienna Circle and Rabbi, covers all writings of his Viennese period until 1938. The works include his dissertation on Nicolai Hartmann, his monograph Prolegomena zu einer kritischen Grammatik inspired by Wittgenstein, his Introduction to Logic, and several articles on linguistic and analytic philosophy, ethics, and religion. It is an important source for anyone working on Schächter, Wittgenstein and/or the Vienna Circle. It provides students and researchers with a special contribution to the Jewish cultural history of Vienna before the Shoah.
