Aristotle believed that the soul, having integrity, is none other than the body inseparable from its organizing principle, the source and mode of regulation of the body, it is objectively observable behavior. Soul - is the entelechy of the body. The soul can not be separated from the body, but the immaterial, non-skin. That, thanks to which we live, feel and reflect - it's soul. "The soul is the cause as something from the movement as a goal and as the essence of animate bodies."

Thus, the soul is a kind of meaning and form, not matter, not the substrate.

The body is inherent in the living condition, forming its orderliness and harmony. It is the soul, it is a reflection of the actual reality of the world and the eternal Mind. Aristotle gave an analysis of the different parts of the soul: memory, emotions, sensations of the transition to a common perception, and from him - to the generalized representation; on the opinion through the concept of knowledge, and by directly perceived desires - to the rational will.

The soul discriminates, and learns things, but she had a lot of "time spent in error." "To achieve the soul of something authentic in every respect, of course, the most difficult."
