Jewish religion, Greek philosophy and Islamic thought mold the philosophy and theology of Maimonides and characterize his work as an excellent example of the fruitful transfer of culture in the Middle Ages. The authors show various aspects of this cultural cross-fertilization, despite religious and ethnic differences. The studies promptthoughts on a question which is important for the present and the future: How may the different religions, cultures and concepts of knowledge continue to be conveyed in synthesis? The volume publishes the lectures given at the July 2004 international congress at the occasion of the 800th anniversary of Maimonides¿ death.
