  The centuries following the remarkable achievement of Ibn Sina (Avicenna; d. 1037) were a remarkably creative period in the sciences and philosophy. Sa‘d ibn Mansur Ibn Kammūna, a Jew from Baghdad, actively participated in the lively discourse of his day. In his copious writings he takes up the entire gamut of philosophical issues discussed by his contemporaries. Editions, translations and studies of works by Ibn Kammūna and other thinkers of the time have appeared in recent years. Nonetheless, it remains difficult at this stage to contextualize Ibn Kammūna’s work, or to decide wherein lies his most noteworthy contribution.
