Reason, which is one of the sources of knowledge, is divided into theoretical and practical; There is no difference in the existence of theoretical intellect and its role in the perception of generalities. But there is a difference in the fact that practical intellect has an existence independent of theoretical intellect and is evidence; Some philosophers deny the existence of practical reason independent of theoretical reason and some believe in it; The second group, some deny the perceptual dimension and some believe in evidence of its partiality. Considering the appearance of Mulla Sadra's expressions, it seems at first that he considers the existence of practical intellect to be independent of theoretical intellect by two criteria (separation and contradictory existential verbs) and because of documents such concepts as inference, thought, Troy, conjecture. And inspiration (belief, and judgment), which are associated with perception, attribute partial perception to it. However, in this paper, we came to this conclusion by descriptive-analytical method after minor (not cobra) damage in the two mentioned criteria and considering that all types of partial perceptions have appropriate powers (such as sense, imagination and delusion). That neither practical intellect has an existence independent of theoretical intellect nor can a partial perception be invoked to it, and therefore we should consider Mulla Sadra to be of the same view.
