Qutb al-Din Razi

Quṭb al-Dīn al-Rāzī al-Taḥtānī was a 14th-century Islamic philosopher, logician, jurist, and commentator in the post-Avicennan philosophical tradition. He played a significant role in refining logical and philosophical discourse, particularly in relation to issues such as universals, and was associated with the Shafi'i legal school.

Philosophical and logical contribution

His philosophical corpus includes major works in logic such as Taḥrīr al-qawāʿid al-manṭiqiyya and Lawāmiʿ al-asrār, as well as philosophical commentaries like al-Muḥākamāt bayna sharḥay al-Ishārāt.
He contributed significantly to the study of universals, particularly through critical engagement with Avicenna’s theory of the natural universal the view that universal quiddity exists within particulars as a part of their essence.
His treatises such as Risāla fī taḥqīq al-kulliyāt and Risālat al-maʿmūla fī al-taṣawwur wa-l-taṣdīq shaped later debates in predication, definition, and universal concepts.
