   Farabi expounds upon this and other issues pertaining to the soul in his wide-ranging masterpiece, “Principles of the Views of the Citizens of the Perfect  State.”[13] He recounts the various faculties of the soul, following the model of Aristotle's De anima, emphasizing the presence of an inclination or propensity (nizâ‘) concomitant with each  one.[14] Thus, the senses immediately like or dislike what they perceive, depending on whether it is attractive or repulsive to them. This affective reaction accompanies the imaginative faculty as well as the practical intellect, which chooses its course of action accordingly.
