 For Avicenna, the faculty of imagination plays crucial roles in steps (1) and (3). Imagination enables us to arrive at meaningful propositions by exploring our storage of previously grasped concepts and combining them to make various ordered structures of concepts (and to examine whether or not they form a meaningful proposition). Moreover, imagination enables us to consider combinations of propositions in order to find the suitable (series of consecutive) syllogism(s) which can lead us to the desired proposition. The most crucial part of this process is to find suitable middle terms for the syllogisms which can lead us to the desired conclusion. In Avicenna’s philosophy, the faculty of imagination undertakes this search operation. An immediate question regarding this view is how imagination, as a bodily faculty, can entertain universal concepts that are supposed to be fully immaterial intelligible entities. Various possible answers to this question are investigated by, among others, Gutas (2001), Adamson (2004), and Black (2013). In Ibn al-Haytham’s philosophy, this is the faculty of distinction that plays the central role regarding (1) and (3). (More on (3) will be said in the next section).
