God moves the highest sphere. It is formed of the four essences of Empedocles, and its motion is from higher to lower or vice versa. Movement, which comes from the heavenly bodies, is the proximate cause of all the becoming in the world. In the cosmology of Aristotle there are some theoretical points that are worthy of consideration. Precisely because these points are theoretical they do not have essential dependence upon his physics.

Psychology Life is called soul by Aristotle, and is the form of organized matter, and the principle of immanent action . Consequently, living beings are distinguished from minerals, whose form is the principle of transient action . Sensible cognition, sensation, is objective and presupposes a physical fact, a contact of the object with an organ or sense of the subject, who then transforms the physical contact into a psychic act, or cognition of the object. The proper object of sensitive knowledge is the individual, the particular, the contingent and material thing. The intellect, on the other hand, has as its object the universal, the necessary, the immutable, the essences, the forms of things abstracted from their individuation.
