İbn Sînâ’da İdrak Mertebeleri ve İkinci Felsefî Ma’kûller

Perception and its quality are one of the most significant problems of philosophy. Ibn Sīnā expresses four different perception levels which are sense perception, imaginative perception, illusory perception and intellectual perception. In this regard, the human soul perceives the objects through their sense abilities. Then, they deliver these forms to the imagination skills, the mind separates the material accidents which this form contains and prepares the grounds required for the intellectual forms. Active intellect, then, gives intellectual forms to the human soul. There are other concepts that are perceived with senses in the human mind other than these concepts. These universal concepts do not belong to objective universe but to subjective universe. Fārābī was the first person in Islamic philosophy tradition to make this distinction and classified the intelligibles in two categories as primary and secondary intelligible. Ibn Sīnā adopts this classification and adds new explanations regarding the issue.
