Gustav Landauer was an unconventional anarchist who aspired to a return to a communal life. His antipolitical rejection of authoritarian assumptions is based on a radical linguistic scepticism that could be considered the theoretical premise of his anarchism. The present volume aims to add to the existing scholarship on Landauer by shedding new light on his work, focussing on the two interrelated notions of skepsis and antipolitics. In a time marked by a deep doubt concerning modern politics, Landauer's alternative can help us to more seriously address the struggle for a different articulation of our communitarian and ecological needs.

Don Isaac Abravanel (1437-1508) was one of the great inventors of Jewish modernity. A merchant, banker, and court financier, a scholar versed in both Jewish and Christian writings, a preacher and exegete, a prominent political actor in royal entourages and Jewish communities, Abravanel was one of the greatest leaders and thinkers of Iberian Jewry in the aftermath of the expulsion of 1492. This book, the first new intellectual biography of Abravanel in twenty years, depicts his life in three cultural milieus-Portugal, Castile, and post-expulsion Italy-and analyzes his major literary accomplishments in each period. Abravanel was a traditionalist with innovative ideas, a man with one foot in the Middle Ages and the other in the Renaissance. An erudite scholar, author of a monumental exegetical opus that is still studied today, and an avid book collector, he was a transitional figure, defined by an age of contradictions. Yet, it is these very contradictions that make him such an important personality for understanding the dawn of Jewish modernity.

Almost five hundred years after his death, Don Isaac Abravanel (1437-1508) remains a legendary figure of Sephardic history, and above all of the Expulsion of 1492. There are numerous"portraits" that have been painted of him by pre-modern and modern scholars. And still we hesitate and cannot discern which is the true one. This first critical edition of Abravanel's Portuguese and Hebrew letters opens a unique window on a complex cultural process of assimilation and dissimulation of humanism among the fifteenth-century Jewish elite. On the one hand, it establishes Abravanel's assimilation of Iberian humanism and of major aspects of the Petrarchian consolatio; on the other hand, it points at the strategies used by him to dissimulate and adapt humanism to Jewish leadership. The duality of Jewish humanists like Don Isaac was obviously a great richness, but it indicated as well their difficulty in expressing themselves coherently and comprehensively in one of the two agoras - Jewish or Christian - in which they were involved as literati and writers. The present edition and study of Abravanel's Portuguese and Hebrew letters sheds a new light on the complexity of this new figure of the Jewish humanist.
