The discussion of man’s existence and his truth and station in the world of creation has always attracted the attention of philosophers as one of the important philosophical issues. Muslim philosophers have also dealt with the problem of man in their discussions. The fundamental point in philosophical anthropology is to speak about the truth of man as a distinct and chosen existent among all others. Abulhassan ‘Amiri Nishaburi, the Iranian Muslim philosopher, is one of the thinkers who has posed certain discussions regarding the truth of man in his philosophical works. As a result, here the writers have compared his views in this regard with those of Mulla Sadra as a distinguished philosopher with some novel theories about the truth of man. In doing so, they have tried to analyze their ideas and reveal their points of agreement and disagreement. Here, their conception of man as a creature of God composed of soul and body, their conception of the soul as the truth of man and, as a result, their opposition to materialistic approaches can be considered to be among their common points. On the other hand, their views concerning the body-soul relationship and its quality can be viewed as their points of difference. Mulla Sadra believes that the body-soul relationship is a necessary and ontological one, and introduces the steam-like spirit as the mediator between the two. Then, by posing the theory of corporeal origination, he provides a more comprehensive theory. Nevertheless, ‘Amiri considers this relationship to be an accidental one and does provide a clear explanation to justify his position in this regard. It is emphasized that both of them conceive of the intellect as one of the levels of the soul, the element distinguishing man from other existents, and the criterion for the truth of man.
