【Summary】

In Tajrīd al-Iʿtiqād, Naṣīr al-Dīn al-Ṭūsī critically examines prevailing philosophical arguments for the existence of immaterial intellects, identifying conceptual weaknesses without fully rejecting the doctrine. In a later, concise treatise devoted specifically to this issue, he presents an original proof for the existence of a separate, immaterial intellect based on the ontological status of extra-mental truths (ḥaqāʾiq nafs al-amr).

Having established the existence of a transcendent intellectual reality, al-Ṭūsī identifies it with the Qurʾānic notions of the Lawḥ Maḥfūẓ (Preserved Tablet) and Kitāb Mubīn (Clear Book), understood as loci of comprehensive knowledge of all that was and will be. This innovative synthesis of philosophical reasoning and scriptural concepts attracted sustained attention from later Muslim scholars.

The treatise was discussed and cited in major philosophical and theological works, including Mullā Ṣadrā’s Asfār al-Arbaʿa and al-Taftāzānī’s Sharḥ al-Maqāṣid, and inspired numerous independent commentaries and glosses by scholars such as Shams al-Dīn Kīshī, Jalāl al-Dīn Dawānī, Shamsā Gīlānī, and Ḥusayn Ilāhī Ardabīlī.
The present volume offers a critical edition of al-Ṭūsī’s treatise together with its principal commentaries, based on a comprehensive survey of extant manuscripts.
