In response to the grim realities of the present world Jewish thought has not tended to retreat into eschatological fantasy, but rather to project utopian visions precisely on to the present moment, envisioning redemptions that are concrete, immanent, and necessarily political in nature. In difficult times and through shifting historical contexts, the messianic hope in the Jewish tradition has functioned as a political vision: the dream of a peaceful kingdom, of a country to return to, or of a leader who will administer justice among the nations. Against this background, it is unsurprising that Jewish messianism in modern times has been transposed, and lives on in secular political movements and ideologies. The purpose of this book is to contribute to the deeper understanding of the relationship between Jewish thought, utopia, and revolution, by taking a fresh look at its historical and religious roots. We approach the issue from several perspectives, with differences of opinion presented both in regard to what Jewish tradition is, and how to regard utopia and revolution. These notions are multifaceted, comprising aspects such as political messianism, religious renewal, Zionism, and different forms of Marxist and Anarchistic movements.
