The centuries immediately following upon the monumental achievements of Avicenna (d. 1036) have been rightly characterized as a golden age of science and philosophy. Generation after generation scrutinized the Avicennan legacy, explicating and expanding upon the wealth of writings left by the master. Critical thinking in logic and astronomy, medicine and metaphysics spurred many new developments. This volume presents seventeen essays on Avicenna, his followers and his critics, many of whom are just now being introduced to western scholarship. The contributors to Avicenna and his Legacy include both established scholars as well as some of the best of the new generation.
