It is a common saying that Islamic philosophy ended after the Iranian scientist and philosopher, Avicenna [Ebn-e Sina](d. 1037 A.D.). But is that true? The recently discovered Nur al-Fu’ad, “Inner Light,” written in Persian by an innovative exponent of the Illuminationist (Ishraqi) school, Shihab al-Din Kumijani (d. 1895 A.D.,) shows that in fact systematic, analytical discourse continued to evolve into the 19th century, especially in Iran. Based on four manuscripts, this first edition of Nur al-Fu’ad—one among hundreds of unpublished philosophical works in Arabic and Persian dating from the 12th - 19th century—should be of great interest to scholars, in particular as it shines the light on Iranian philosophy.
