Abstract

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:God’s Knowledge of the World: Medieval Theories of Divine Ideas from Bonaventure to Ockham by Carl A. VaterBenjamin R. DeSpainVATER, Carl A. God’s Knowledge of the World: Medieval Theories of Divine Ideas from Bonaventure to Ockham. Washington, D.C.: The Catholic University of America Press, 2022. xi + 294 pp. Cloth, $75.00Carl Vater skillfully blends historical and constructive concerns in his study of medieval theories of the divine ideas. The book, first, makes a significant contribution to the body of scholarly resources on medieval philosophy by systematically mapping out the complex intellectual history of the divine ideas between the years 1250 and 1325. Throughout the work Vater displays a staggering command of the relevant literature, figures, and ideas from this period of philosophical development. Second, he provides a robust defense and promotion of John Duns Scotus’s theory of the divine ideas, which he regularly insists is the best theory. Through careful analysis of the often subtle differences in medieval articulations of the divine ideas to answer the questions of how God knows and produces creatures, Vater makes the case that Scotus avoided certain pitfalls in earlier theories that rely on a flawed understanding of relations influenced, principally, by Avicenna’s notion of essence.The book itself is divided into five parts with each systematically detailing a particular theory, beginning with the “imitability theory” represented by Thomas Aquinas, Henry of Ghent, and Bonaventure—the one figure, in Vater’s narrative, capable of escaping Scotus’s subsequent critiques. According to Vater, the imitability theory is defined by several notable characteristics, including that the divine ideas are “secondary objects of the divine intellect when it knows the divine essence,” that they perform both cognitive and causal roles, that they are relations, and that there are many of them. The “infinite intellect theory” critiques the imitability theory for depending on a notion of relations that is mistaken for supposing that relations can be known before the terms of the relation are themselves known. In this section, Vater examines the works of Peter John Olivi and his student Petrus de Trabibus. The third part considers what Vater calls the “objectum cognitum theory” developed by James of Viterbo. Here, according to Vater, we encounter the first signs, following Olivi and de Trabibus’s critique of the imitability theory, of the shift away from identifying the divine ideas with relations to defining them as creatures themselves. This shift culminates in the “creatura intellecta theory” introduced by Richard of Mediavilla, but it is not properly developed until Scotus, who concludes that “God knows relations because he knows possible creatures.” The section ends with an analysis of Scotus’s influence on the theories of early Thomists and Scotists, including John of Paris, Thomas of Sutton, and Henry of Harclary. In the fifth part, Vater turns to the “nominalist theory” of Peter Auriol and [End Page 373] William of Ockham. Although both Auriol and Ockham offer accounts of the divine ideas, these are, as Vater says, little more than nods to the Augustinian tradition that ultimately amount to a rejection of the divine ideas.Vater’s approach to these medieval theories has many strengths. By not only classifying the prominent theories during this period but also systematically organizing his interpretation of each respective author, he is able to create a comparative framework for assessing the central issues at play in the divine ideas, such as their status, definition, cognitive and causal roles, plurality and unity, exemplarity, and the question of nonexistent possibles, and he traces variations in each area to identify where change, development, and critique are actually occurring within this seventy-five years of intellectual history. He also is attentive to figures often overlooked in larger narrations of medieval philosophy, and he locates their contributions to the varied development of the divine ideas. More importantly, however, Vater is able to maintain coherence in his evaluation of these complex, intertwining layers of medieval philosophical reflection by constantly returning to the overarching theme of relations in the movement from identifying the divine ideas with relations to approaching them as creatures themselves. Vater is correct when he notes that the divine ideas form a...
