Final answer:
Aristotle identified God as the 'prime mover' or 'First Cause,' a non-interventionist self-thinking entity, which he considered as the necessary existence causing itself and other contingent beings.
Step-by-step explanation:
Aristotle, who is often referred to as "the Philosopher," defined God as the prime mover and "thought thinking itself." He believed that the existence of the universe needed an explanation beyond an infinite regression of causes, thus leading to the concept of a First Cause. Aristotle's interpretation of God was not interventionist; instead, God was the necessary existence that brought other contingent beings into existence and served as the ultimate cause in the universe, best thought of as complete actuality or perfection. Therefore, God was motivated by no external force but acted as a self-contained actuality whose nature was to think.
