Joseph Dan, the Gershom Scholem Professor of Kabbalah Emeritus at the Hebrew University and long-time Professor of Jewish Studies at the Freie Universitat Berlin, is one of the most influential figures in the fields of Jewish mystical thought, homiletical and ethical literature, modern Messianism and Hasidism, and contemporary 'belles-lettres'. His studies of the diverse aspects of Jewish creativity, with close attention to the dialectics of religious-cultural continuity versus historical innovation, provide a comprehensive overview of the complex history of Jewish thought and its multiple creative faces. It is precisely for this reason, to honor Joseph Dan's multifaceted research, that his many colleagues, students, and friends, scattered among universities around the world, have decided to focus their contributions in this Festschrift on the continuing process of creation and re-creation in Jewish thought throughout the centuries.
