Menaḥem Mendel Schneerson (1902-1994) was the seventh and seemingly last Rebbe of the Habad-Lubavitch dynasty. Marked by conflicting tendencies, Schneerson was a radical messianic visionary who promoted a conservative political agenda, a reclusive contemplative who built a hasidic sect into an international movement, and a man dedicated to the exposition of mysteries who nevertheless harbored many secrets. Schneerson astutely masked views that might be deemed heterodox by the canons of orthodoxy while engineering a fundamentalist ideology that could subvert traditional gender hierarchy, the halakhic distinction between permissible and forbidden, and the social-anthropological division between Jew and Gentile. While most literature on the Rebbe focuses on whether or not he identified with the role of Messiah, Elliot R. Wolfson, a leading scholar of Jewish mysticism and the phenomenology of religious experience, concentrates instead on Schneerson's apocalyptic sensibility and his promotion of a mystical consciousness that undermines all discrimination. For Schneerson, the ploy of secrecy is crucial to the dissemination of the messianic secret. To be enlightened messianically is to be delivered from all conceptual limitations, even the very notion of becoming emancipated from limitation. The ultimate liberation, or true and complete redemption, fuses the believer into an infinite essence beyond all duality, even the duality of being emancipated and not emancipated--an emancipation, in other words, that emancipates one from the bind of emancipation. At its deepest level, Schneerson's eschatological orientation discerned that a spiritual master, if he be true, must dispose of the mask of mastery. Situating Habad's thought within the evolution of kabbalistic mysticism, the history of Western philosophy, and Mahayana Buddhism, Wolfson articulates Schneerson's rich theology and profound philosophy, concentrating on the nature of apophatic embodiment, semiotic materiality, hypernomian transvaluation, nondifferentiated alterity, and atemporal temporality.

On the last day of his life, Otto Neurath had given help to a Chinese philosopher who was writing about Schlick. Only an hour before his death he said to me: "Nobody will do such a thing for me." My answer then was: "Never mind, you have Bilston, isn't that better?" There were con sultations in new housing schemes, an exhibition, and hopes for a fruitful relationship of longer duration. I did not dream at that time that I would one day work on a book like this. The idea came from Horace M. Kallen, of the New School for Social Research, New York, years later; to encourage me he sent me his selection from William James' writings. Later I met Robert S. Cohen. Carnap had sent him to me with the message: "If you want to find out what my political views were in the twenties and thirties, read Otto Neurath's books and articles of that time; his views were also mine." In this way Robert Cohen became ac quainted with Otto Neurath. Even more: he became interested; and when I asked him, would he help me as an editor of an Otto N eurath volume, he agreed at once. In previous years I had already asked a number of Otto Neurath's friends to write down for me what they especially remembered about him.

Throughout the ages philosophers have examined their own lives in an attempt both to find some meaning and to explain the roots of their philosophical perspectives. This volume is an introduction to philosophical autobiography, a rich but hitherto ignored literary genre that questions the self, its social context, and existence in general. The author analyzes representative narratives from antiquity to postmodernity, focusing in particular on three case studies: the autobiographies of St. Augustine, Rousseau, and Sartre. Through the study of these exemplary texts, philosophical reflection on the self emerges as a valid alternative to Freudian psychoanalysis and as a way of promoting self-renewal and change.
