Abu Hafs 'Umar al-Suhrawardi (1145-1234) is the author of a classic work of Muslim piety, a key figure in the rise of institutional Sufism in the form of "orders" called "tariqas," and the influential eponym of one of these famous orders. This book presents studies, editions, and English translations of his shorter treatises that were originally penned in Arabic and Persian. Relying on global archival research, the book discovers materials that shed new light on his teachings and networks, as it traces the context, sources, and reception of his works. Carefully identifying the authentic works of 'Umar al-Suhrawardi, the book presents significant new information on a key moment in the history of Muslim piety and mysticism.

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.
