Ṣadr al-Dīn Muḥammad b. Isḥāq b. Muḥammad b. Yūnus Qūnawī;
[alternatively, Qūnavī, Qūnyawī], (Persian: صدر الدین قونوی), (Turkish: Sadreddin Konevî), (1207-1274 CE/605-673 AH), was a Persian philosopher, and one of the most influential thinkers in mystical or Sufi philosophy. He played a pivotal role in the study of knowledge—or epistemology, which in his context referred specifically to the theoretical elaboration of mystical/intellectual insight. He combined a highly original mystic-thinker, Muḥyī al-Dīn Ibn ‘Arabī (1165-1240 CE/560-638 AH), whose arcane teachings Qūnavī codified and helped incorporate into the burgeoning pre-Ottoman intellectual tradition, on the one hand, with the logical/philosophical innovations of Ibn Sīnā (Lat., Avicenna), on the other. Though relatively unfamiliar to Westerners, the spiritual and systematic character of Qūnawī’s approach to reasoning, in the broadest sense of the term, have found fertile soil in modern-day Turkey, North Africa and Iran not to mention India, China, the Balkans and elsewhere over the centuries.
