Thomas Davidson taught a philosophy called "apeirotheism", a "form of pluralistic idealism...coupled with a stern ethical rigorism" which he defined as "a theory of Gods infinite in number." The theory was indebted to <answer>Aristotle</answer>'s pluralism and his concepts of Soul, the rational, living aspect of a living substance which cannot exist apart from the body because it is not a substance but an essence, and nous, rational thought, reflection and understanding. Although a perennial source of controversy, <answer>Aristotle</answer> arguably views the latter as both eternal and immaterial in nature, as exemplified in his theology of unmoved movers. Identifying <answer>Aristotle</answer>'s God with rational thought, Davidson argued, contrary to <answer>Aristotle</answer>, that just as the soul cannot exist apart from the body, God cannot exist apart from the world.
