Abū Manṣūr al-Māturīdī (d. 944), from Samarqand in Transoxiana, is the eponym of one of the main Sunnī theological traditions. As a practitioner of kalām (dialectical theology), al-Māturīdī’s approach was often at odds with those engaged in falsafa, the main Arabic philosophical discourse in the Islamic world. However, a close examination of al-Māturīdī’s surviving theological text, Kitāb al-tawḥīd, not only reveals influence in some issues from al-Kindī (d. 873), one of the earliest of the falāsifa, but also interesting philosophical positions and arguments. In this chapter, I show that al-Māturīdī articulates a version of nominalism in which a given concrete particular (ʿayn) can be considered a bundle of its possessed qualities (ṣifāt), or as they would be termed today, tropes. He derives this understanding from experience of the world and applies it analogically to God to affirm substantive divine attributes. He also uses his theory of properties to argue against the concept nominalism of a Muʿtazilī opponent, likely Abū al-Qāsim al-Kaʿbī (d. 931). Al-Māturīdī’s philosophical side, albeit with its openly theological agenda, should be made more accessible to historians of philosophy. This chapter is one of the first attempts to treat al-Māturīdī seriously as a philosopher and to present his thought in a way that is relevant to contemporary debates in ontology and for comparison with other medieval traditions
