Abstract

Alongside his much-discussed theory that humans are permanently, if only tacitly, self-aware, Avicenna proposed that in actively conscious self-knowers the subject and object of thought are identical. He applies to both humans and God the slogan that the self-knower is “intellect, intellecting, and object of intellection (‘aql, ‘āqil, ma‘qūl)”. This paper examines reactions to this idea in the Islamic East from the 12th-13th centuries. A wide range of philosophers such as Abū l-Barakāt al-Baghdādī, Faḫr al-Dīn al-Rāzī, al-Šahrastānī, Šaraf al-Dīn al-Mas‘ūdī, al-Abharī, al-Āmidī, and Naṣīr al-Dīn al-Ṭūsī raised and countered objections to Avicenna's position. One central problem was that on widely accepted definitions of knowledge – according to which knowledge is representational or consists in a relation – it seems impossible for the subject and object of knowledge to be the same. Responses to this difficulty included the idea that a self-knower is “present” to itself, or that here subject and object are different only in “aspect (i‘tibār)”.
