The purpose of this paper is to present a comprehensive and systematic study of Avicenna's account of animal self-awareness and cognition. In the first part, I explain how, for Avicenna, in contrast to human self-awareness, animal self-awareness is taken to be indirect, mixed-up (makhlūṭ), and an intermittent awareness. In his view, animal self-awareness is provided by the faculty of estimation (wahm); hence, in the second part, I explore the cognitive role of the faculty of estimation in animals, and how that relates to self-awareness. The faculty of estimation, according to Avicenna, serves to distinguish one's body and its parts from external objects, and plays a role in connecting the self to its perceptual activities. It follows that animal self-awareness, unlike human self-awareness, is essentially connected to the body. In the third part of the paper, I show that, while Avicenna denies animals awareness of their self-awareness, he explicitly affirms that animals can grasp their individual identity, but, unlike humans, do so incidentally, as part of their perceptual awareness.
