The rational understanding of the self is referred to as "Philosophical Psychology." Philosophical epistemology, by distinguishing humans into selves and faculties, evaluates and measures human cognitive faculties. Each faculty is an instrument of knowledge for one of the worlds or hierarchies of existence because each has an origin beyond human existence and is capable of perceiving its own related existence. This research aims to clarify the position of philosophical psychology in two works, Hadīqah and Sīral-Ibād, through a comparative analysis of psychology in the views of the Peripatetic philosophers. Thus, by considering Avicenna's perspective on the self in the section on the soul in his book Shifā and the views of the scholars of the City of Virtue of Al-Farabi, it reaches the structure of philosophical anthropology in Peripatetic wisdom and examines Sīral-Ibād and Hadīqah from this perspective. This research examines the perspective that leads to the perfection of the human self-culminating in happiness and light, seeking its starting point in psychology, as ontology and self-awareness in Sanāyi’s view are based on psychology. Sanāyi, in the manner of philosophers, dissects humans and the world for identification into disconnected and fragmented parts; the fragments connect through numerous intermediaries; thus, existence is ranked and tiered, just as it was for identification. According to Sanāyi, the stages of human journey exist in the worlds of perception, and the beginning of happiness is based on sensory perception. Ascension in the structure of philosophical psychology is not an ascent but a return to the origin.
