The present volume is the product of a conference held in 2005 at the Institute for Advanced Studies in Jerusalem to mark the fifteenth anniversary of the passing of Shlomo Pines (1908-1990). The papers assembled in this volume give a glimpse of the many fascinating insights that can be obtained by examining interactions between religious traditions and schools of thought. The participants, some of them Pines's former students and all of them contributors to the field of cross-cultural studies, seek to explore meaningful areas in the transmission of literary and intellectual content across the boundaries of religions and cultures, in which Muslims, Christians and Jews took part in antiquity and in the Medieval period.
