In this volume, the John Duns Scotus Research Group under the direction of Professor Antonie Vos at Utrecht University has provided scholars of medieval philosophy and theology with an accurate and readable English translation of John Duns Scotus's earliest treatment of divine foreknowledge and future contingents. Interweaving the Latin text of Scotus's Lectura with their translation, the translators provide a very useful commentary on Scotus's text on the facing pages. The Lectura, as the introduction to the volume rightly notes, is the written version of Scotus's first lectures at Oxford on Peter Lombard's Sentences and, despite its early date, it reveals the extent to which the central ideas of Scotus's thought were already in place. Furthermore, although many of the Subtle Doctor's characteristic doctrines are mentioned herein, pride of place is given, both in the introduction and in the commentary accompanying the text, to Scotus's outstanding contribution to the medieval discussion of divine foreknowledge: his substantial revision of the modal notions of necessity, possibility, and contingency. The text translated in this volume is the entirety of Scotus's commentary on distinction thirty-nine ofthe first book of the Lombard's Sentences, the customary place in medieval theological commentaries for raising questions about the reality of future contingents, their knowability, and the compatibility of future contingency with divine foreknowledge. In his commentary, Scotus raises five questions in connection with distinction thirty-nine: 1) whether God has determinate knowledge of things according to every aspect of their existence, including the future; 2) whether God has infallible knowledge of things according to every aspect of their existence; 3) whether God has immutable knowledge; 4) whether God necessarily knows every changeable aspect of things; and 5) whether the contingency of things is compatible with God's knowledge. Prompted by these questions, Scotus reviews traditional explanations of God's infallibility and immutability as well as contemporary accounts of how the future is knowable. Regarding the former, Scotus first introduces an explanation, similar in its outlines to that found in St. Bonaventure's Commentary on the Sentences and St. Thomas's Summa theologiae, of the infallibility of God's knowledge b,ased on the preeminence and lucidity of the Divine Ideas. According to this explanation, the Divine Ideas are so comprehensive and so distinctive that they allow any mind aware of them to perceive the most intimate and subtle connections between things as well as the things themselves; yet the things known through the Ideas need not be necessary since the mode of the cognition does not necessarily reflect the mode of the BOOK REVIEWS 507 things known through it. Scotus's main objection to this explanation is that it does not adequately account for how God could know contingent things since the truth of contingent things is not, by definition, contained in the notions of the simple terms, to which the Divine Ideas are often likened, composing a contingent proposition; indeed, if the truth of contingent things were contained in the notions of the simple terms composing the propositions that express them, the truth of contingent things would not be contingent but necessary . The failure of this explanation is traceable, in Scotus's view, to an insufficient appreciation for the role of the Divine Will in the production of created things. As to the matter of how the future is knowable, the Subtle Doctor reviews Aquinas's theory that God's eternity is present to all times. Scotus rejects this theory on the ground that, among other difficulties, God cannot cause something new in the future since the future, qua present, is already laid out before God as something that is caused. Hence, unless the theory can accommodate the possibility of God causing something twice, God's causal role in the future is nugatory. In other words, the notion of the past and the future being somehow...
