Naṣīr al-Dīn Ṭūsī (d. 672/1274) was an influential philosopher, theologian, mathematician and astronomer, besides being the first director of the famous observatory at Marāghah near Tabriz as well as a man of politics. The author of a large number of scholarly works, he is especially famous for such treatises as his Tajrīd al-iʿtiqād on theology; the Zīj-i Īlkhānī on astronomy; the Ḥall mushkilāt al-Ishārāt ; his influential commentary on Avicenna's (428/1037) Kitāb al-ishārāt wal-tanbīhāt on philosophy and logic; and his Akhlāq-i Nāṣirī on ethics. In the brief Arabic treatise that is the subject of this publication, Ṭūsī proves that there is a separate intellect in which all contingent being is semperternally represented, unchanging, as a kind of 'interface' between God and the human mind ( dhihn ). Even though this treatise is extremely short, it certainly had an impact, as is clear from the variety of critical reactions in the commentaries and glosses published alongside it in this volume.
