"Alexander Orwin combines extraordinary linguistic skills with a finely tuned knowledge of political philosophy which he uses to cast new light on Alfarabi's concept of Umma, and to reveal and explore the core of his teaching." (Joshua Parens, University of Dallas) "This is an ambitious book. Alexander Orwin transforms Alfarabi's abstract works into rich and evocative characterizations of the dilemmas posed by the social, ethnic, and political forces of his time." (Miriam Galston, author of Politics and Excellence: The Political Philosophy of Alfarabi)
