Aquinas accepts the harmony of faith and reason, but he does not think that such harmony is always easily arrived at. After making some background points about his views on faith, reason, philosophy, and theology, I explore two cases drawn from his Christology. In the first, philosophical thinking influences how we understand revelation; in the second, theological thinking influences how we understand a topic normally thought of as part of philosophy. In both cases, harmony is not pre-given but instead arrived at only through a process of adjustment.

This dissertation is an investigation of ontological priority. The Introduction argues that although philosophers have often been concerned with the things that are ontologically prior, they have seldom addressed the question of what ontological priority is. ;Part One gives a detailed analysis of what ontological priority is. Chapter 1 notes that there are two competing theories available: according to the first, ontological priority is a dependence relation; according to the second, it is a degrees-of-being relation. Since the two views are in themselves irreconcilable and since there are no good grounds for choosing between them, it is better to find a "higher" theory that encompasses both of them. Chapter 2 lays the groundwork for the development of this "higher" theory by examining the Scotistic notion of "essential order", a notion that includes the two relations that have been called 'ontological priority' as noted in Chapter 1. Chapter 3 adapts Scotus's understanding of essential order to formulate a definition of ontological priority. The definition does not define just one relation; rather, it gives membership criteria for an entire class of "ontological priority relations". ;Part Two examines some of the members of the class of ontological priority relations. Chapter 4 examines dependence and concludes three things: first, that the received understanding of dependence is incorrect; second, that dependence properly understood is an ontological priority relation; third, that the relation that is usually thought to be dependence is also an ontological priority relation. Chapter 5 examines degrees-of-being. Since the question of what degrees-of-being is is too complicated to deal with in the context of the dissertation, the chapter examines several theories and shows that degrees-of-being is an ontological priority relation according to any of the theories. ;The Conclusion shows some relations among the three ontological priority relations discussed in Part Two. It also shows briefly how the concept of ontological priority relations can be used to talk about the orderings of the universe. Finally, it points the way to further investigation.

The dissertation is a critical study of Thomas Aquinas's views on the hypostatic union. It examines the Latin texts of all of Thomas's major discussions of this topic. In the first chapter, the concepts of nature and person are discussed, and it is argued that these concepts, as Thomas understood them, led to a very problematic position in an early quodlibetal disputation. In the second chapter, the concepts of union-in-person and union-in-nature are discussed, and this permits a better understanding of how the concepts of person and nature are meant to be used than was available in the first chapter. The third chapter deepens the reflection on the hypostatic union by contrasting this relation with other kinds of relations and especially by explaining what Thomas means by denying that the hypostatic union is accidental. The fourth chapter returns to the difficulty brought out in chapter one and locates it in a tension between traditional modes of speech and the technical Thomistic use of the word natura. The fifth chapter discusses the controverted issues surrounding Thomas's understanding of Christ's metaphysical unity. Throughout the dissertation, secondary literature is discussed as appropriate

The hypostatic union of Christ, namely his being simultaneously human and divine, is one of the founding doctrines of Christian theology. In this book Michael Gorman presents the first full-length treatment of Aquinas's metaphysics of the hypostatic union. After setting out the historical and theological background, he examines Aquinas's metaphysical presuppositions, explains the basic elements of his account of the hypostatic union, and then enters into detailed discussions of four areas where it is more difficult to get a clear understanding of Aquinas's views, arguing that in some cases we must be content with speculative reconstructions that are true to the spirit of Aquinas's thought. His study pays close attention to the Latin texts and their chronology, and engages with a wide range of secondary literature. It will be of great interest to theologians as well as to scholars of metaphysics and medieval thought.
