This volume brings together essays spanning four decades of Nasr's prolific and learned scholarship.

This volume gathers together the numerous essays by the Iranian metaphysician and ontologist, Seyyed Hossein Nasr, on Islamic philosophers and the intricate relationship between Persian culture and its philosophical schools. Brought together into a single volume for the first time, these essays span four decades of Nasr's prolific and learned scholarship on the development of Islamic philosophy, as well as the general history of Islam, and expound his belief that philosophy is not merely a rational but a sacred activity.

'The book demonstrates Nasr's profound and extensive knowledge of the Islamic intellectual tradition and his exceptional scholarship which is the result of a rare combination of a traditional Islamic intellectual training and a Western education. It is also a witness to his tremendous contribution to studies on the structure, history and development of Islamic thought and philosophy which is of great importance and value to scholars and students of Islamic thought and philosophy both in the West and in the Muslim world.' - Zailan Moris, The Muslim World
