This volume introduces the major classical Arabic philosophers through substantial selections from the key works (many of which appear in translation for the first time here) in each of the fields--including logic, philosophy of science, natural philosophy, metaphysics, ethics, and politics--to which they made significant contributions. An extensive Introduction situating the works within their historical, cultural, and philosophical contexts offers support to students approaching the subject for the first time, as well as to instructors with little or no formal training in Arabic thought. A glossary, select bibliography, and index are also included.
