Aristotle: The Unmoved Mover

Our everyday knowledge and the knowledge of the sciences are based on presuppositions of different fundamentality. The most general framework includes opinions about being, then the way a particular language sorts reality, precepts of logic, what Husserl called the natural attitude. Furthermore, specific content-related prerequisites and convictions are decisive in the individual sciences. Also modern readers of Aristotelian texts share some such specific convictions. I would like to speak of two of them here, since they are evidently false and considerably (...) hindering the understanding of the texts. The first conviction is that Aristotle developed a metaphysics of substance, the second that he thereby founded a theology with an ‘unmoved mover’ as its center, which can be identified with God. Since this text is a kind of pamphlet, I have summarized the remarks in endnotes. (shrink)

Biology and theology are interdependent theoretical sciences for Aristotle. In prominent discussions of the divine things (the stars and their unmoved movers) Aristotle appeals to the science of living things, and in prominent discussions of the nature of plants and animals Aristotle appeals to the nature of the divine. There is in fact a single continuous series of living things that includes gods, humans, animals, and plants, all of them in a way divine. Aristotle has this continuum of divine beings, (...) and a theory of value that corresponds to it, in mind not only in key parts of his theology and biology, but also in his practical philosophy. Here I call attention to some important texts and attempt to offer a coherent account of them, without being able to enter into the usual interpretive disputes. I begin by clarifying the terms “theology” and “biology” and their place in Aristotle's division of philosophy. Next, I discuss how Aristotle’s theology is informed by his biology, and then how his biology is informed by his theology. I end by discussing some implications of the interdependence of biology and theology for Aristotle’s ethics and exhortation to philosophy. (shrink)

I argue that the science of the soul only covers sublunary living things. Aristotle cannot properly ascribe ψυχή to unmoved movers since they do not have any capacities that are distinct from their activities or any matter to be structured. Heavenly bodies do not have souls in the way that mortal living things do, because their matter is not subject to alteration or generation. These beings do not fit into the hierarchy of soul powers that Aristotle relies on to provide (...) unity to ψυχή. Their living consists in their activities, not in having a capacity for activity.

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

This article faces the classic problem of the interpretation of what Aristotle calls in de An. III, 5 “the intellect that produces all things”, which is commonly named agent intellect. Historically, there have been two approaches: one that goes back to Alexander of Aphrodisias, who associates the agent intellect with the unmoved mover and the divinity, and another one, associated with Theophrastus but whose major representatives are Philoponus and St. Thomas of Aquinas, who consider that agent intellect is an exclusively (...) human faculty. This last interpretation has been the most accepted historically. Nevertheless, in recent years there has been a resurgence of interpretations of the agent intellect as divine (Caston, Frede, Burnyeat, and others). What we want to demonstrate in this article is that this revival, more than responding to a reinterpretation of the agent intellect, is due to a different understanding of the divinity in Aristotle’s philosophy, which supposes immanent characteristics closer to the human intellect.

Argues that Aristotle regarded the universe, or Totality, as a single substance with form and matter, and that he regarded this substance together with the Prime Mover as a self-mover.
