Abstract
This article focuses on some topics in Jeffrey Brower’s recent and excellent book, Aquinas’s Ontology of the Material World: Change, Hylomorphism, and Material Objects. Part of Brower’s goal for the book is to reconstruct Aquinas’s views. I offer some reflections on Brower’s use of this metaphor of reconstruction, before considering four topics in some detail. These are: 1. Brower’s discussion of the relation between Aristotle’s Ten Categories and the not-obviously-connected four-fold division of being into substance, form, prime matter, and accidental unity. 2. Brower’s interpretation of prime matter as “non-individual stuff.” 3. Brower’s account of numerical sameness without identity along with some discussion of how this is supposed to be useful for solving a particular puzzle about accidental change. 4. I’ll close with some reflections on Brower’s somewhat novel solution to a longstanding problem with Aquinas’s metaphysics of the afterlife.
