Abstract
This intelligent and often subtle introduction to rationalist metaphysics focuses on the development of the concept of substance in Descartes, Spinoza, and Leibniz. After briefly reviewing the Aristotelian background in the introduction, Woolhouse spends the first three chapters presenting the broad outlines of each thinker’s account of substance. These are followed by three chapters devoted more specifically to the metaphysics of extended substance and to foundational issues in early modern physics. Next come two chapters on thinking substance and its relation to extended substance, and finally a chapter on the relation between created and uncreated substance, which Woolhouse describes as "an organizing centre of the whole book".
