The article examines Voegelin's understanding of nous as the ground for theorizing, and relates this back to Aristotle. Aristotle is shown to have understood the activities of nous in two distinct ways. On the one hand, nous is the divine activity of the soul exploring its own ground. But nous is also induction (epagôgê) of the first principles of science through sense perception, memory and experience. The two basic activities of nous are related, but they have different values when it comes to the world of particulars. The argument is that a substantive ethical and political science—one that sheds light on particulars—must include the inductive employment of nous and that the exclusion of this from Voegelin's political science results in some discernible limitations.
The limitations of Eric Voegelin—s work are sometimes difficult to keep in view, particularly while he is expounding upon the totality of Being, the myriad dimensions of human consciousness, and the nature of order in personal, social, and historical existence. But in fact Voegelin's work is more limited than his magisterial tone might suggest. The argument of this article is that while Voegelin offers his readers profoundly important insights into the structure of human consciousness and into what Aristotle called first philosophy, the study of being qua being, he does not offer his readers much in the way of a substantive ethical or political science.
