The connection of human being's levels and the degrees of existence in Mulla sadra

Mulla Sadra, regards existence as something simple and gradual. Rather, he believes that human being have one identity. It is, however, of simplicity and gradation both. For him there are close relation between the stages of soul and the degrees of existence and perceptions. As a result of this relation, every one of human perceptions connects with one of degrees of existence. The knower, in Mulla Sadra, unites with the known and with the active intellect. Then all of existents become the constituents of his essence and man’s relation to them is the same as the relation of the soul to the body. Therefore, it can be said that human being in the every level of knowledge have the same level of existence and his/her world is his/her perceptual data.
