On the Intrinsics of Individual Human Activity

We consider the activities of a matured individual human being. We adopt the opinion that the world is a collection of a variety of independent entities, in which and with which independent entities interact. A matured individual humans being is one independent entity. His/Her activities have a physical component and a mental component. Correspondingly, it has a physical existence, which we will also refer as his/her body, and a mental existence, which we will also refer as his/her mind. Between the two, the physical existence is basic in the sense that a mental existence is always attached to a physical existence. There exist no mental activities without a physical host. An individual interacts with the world through its physical existence. Mental activities are internal and they do not directly interact with the world. The mind receives feedbacks through the sensors attached to the body. The feedbacks presented to the mind are organized subjecting to the a priori framework of space, time and relationships. The mind works on and responds to the feed backs, directing the physical activity of the individual.
