Averroes held the controversial thesis that there is only one separate material or possible intellect for all humans. This paper analyzes a passage from his Long Commentary on the De Anima which has been thought to constitute a primary philosophical argument for the view. It is called the Determinate Particular Argument, because it contends that the material intellect cannot be a determinate particular if it is to be the ontological receptacle of universal intelligible forms. After defending one crucial premise, it (...) will be shown how the key term “determinate particular” must be qualified to avoid an inconsistency with Averroes’s metaphysics and his position on the species membership of separate substances. Given this qualification in the face of competing views, the paper concludes that the Determinate Particular Argument should not be taken as a sufficient and independent argument for Averroes’s full thesis on the intellect.

I argue that Metaphysicsλ‎ is a unified work, and one which is not a continuation of the central books ΖΗΘ‎. It outlines an extensive project in First Philosophy, which has close connections with ΑΒΓΕ‎, but which proceeds on a different trajectory from ΖΗ‎. The principal problem in understanding λ‎ as a whole is how to reconcile Aristotle's explicit presentation of the book as a highly unified study with the disparate character of its two halves – the first a general‐metaphysical enquiry (...) into the features which changeable substances have as being substances of that kind, the second a detailed investigation of the specific character and activity of immaterial substances. My paper aims to show how this reconciliation is possible, and what we can learn about Aristotle's conception of first philosophy as a result. (shrink)
