Metaphysics between Experience and Transcendence: Thomas Aquinas on Metaphysics as a Science. Münster: Aschendorff Verlag, 2021. vii + 246 pp. 38,00€ In the opening chapter of Metaphysics 4, Aristotle states not only that there is a science of being as being and its per se properties but also that it is the task of the metaphysician to investigate the principles and causes of such being. Does this mean that metaphysics comes in two parts—namely, an ontology that investigates being and its properties, followed by a theology that investigates the first principle of being? Or does it mean that the very investigation into being and its properties involves an investigation into the first principle of being—that is, that ontology in some sense is theology? The central purpose of Rudi A. te Velde's newest book is to show that, at least for Thomas Aquinas and those who would follow him, the answer is emphatically the latter: Thomistic metaphysics is essentially the resolutio, or tracing-back, of common being (ens commune) to divine being (ens divinum). This process of resolution situates Aquinas's metaphysics "between experience and transcendence." Unlike natural philosophy, metaphysics is not focused on reality as it is given to us in and through sensory experience. Unlike Christian theology, metaphysics is not focused on God as revealed to us in and through supernatural faith. Rather, it is focused on what both of these—experience and transcendence—presuppose, namely, the fundamental truth that all of reality comes from, and points back to, God as its principle and source. For te Velde, Aquinas's metaphysics is etiology or, as he puts it, "the science of presuppositions." Chapter 1 offers the reader a synoptic view of the basic outlines and contours of Aquinas's metaphysics, both positively and negatively. Positively, te Velde points out that Aquinas understands metaphysics to be an Aristotelian science, that is, a discipline unified around its subject. For the properties of a subject are what we aim to demonstrate when we engage in Aristotelian science, and its principles are what we appeal to when doing so. Negatively, te Velde contrasts Aquinas's view of metaphysics with that of his contemporary, Siger of Brabant, and that of our contemporary, John Haldane. Unlike the former, Aquinas's metaphysics takes common being, which is participated and created (and so does not include God), as its subject. Unlike the latter, Aquinas's [End Page 162] metaphysics is unified by the intelligibility of being in light of its principles. In chapters 2 through 5, te Velde focuses in on particular themes that are of central importance to Aquinas's account of metaphysics. Chapter 2 examines the role of separatio in distinguishing metaphysics from physics and mathematics. Where physics considers things that require matter both to be and to be understood, and mathematics considers things that require matter to be but not to be understood, metaphysics considers things that require matter neither to be nor to be understood. It does so by means of a judgment of separation—a judgment that something (for example, substance, form, and so on) can be without matter. Chapter 3 turns to the topic of resolutio, wherein the mind moves "from the concrete particular to its intelligible ground." Aquinas's metaphysics is marked by a twofold resolution: one in which being and its attributes are grasped as the intrinsic principles of all things, and a second in which God and separate substances are grasped as the extrinsic principles of all things. Chapter 4 then investigates the notion of transcendentality, which arises in the first of those two resolutive processes—for insofar as being and its attributes are common to all things, they are not limited to just one of the ten categories (that is, they are transcendental). Nevertheless, the way in which predicates like "one," "true," and "good" cut across the categories that divide common being is different from the way that they cut across the divide between God and creatures. This difference ushers in chapter 5's discussion...
