In her first book, Marleen Rozemond explicates Descartes's aim to provide a metaphysics that would accommodate mechanistic science and supplant scholasticism.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

The doctrine of God’s absolute simplicity denies the possibility of real distinctions in God. It is, e.g., impossible that God have any kind of parts or any intrinsic accidental properties, or that there be real distinctions among God’s essential properties or between any of them and God himself. After showing that some of the counter-intuitive implications of the doctrine can readily be made sense of, the authors identify the apparent incompatibility of God’s simplicity and God’s free choice as a special (...) difficulty and associate it with two others: the apparent incompatibilities between essential omnipotence and essential goodness, and between perfect goodness and moral goodness. Since all three of these difficulties are associated with a certain understanding of the nature of God’s will, the authors base their resolution of them on an account of will in general and of God’s will in particular, drawing on Aquinas’s theory of will.Taking creation as their paradigm of divine free choice, the authors develop a solution of the principal incompatibility based on three claims: God’s acts of choice are both free and conditionally necessitated; the difference between absolutely and conditionallynecessitated acts of will is not a real distinction in God; and the conditional necessity of God’s acts of will is compatible with contingency in the objects of those acts. The heart of their solution consists in their attempt to make sense of and support those claims.The authors extend their solution to cover the two associated apparent incompatibilities as well.The article concludes with observations on the importance of the doctrine of God’s absolute simplicity for resolving problems in religious morality and in the cosmological argument.

THERE are several answers in Aquinas to the question, what is the ground of the world's intelligibility. The fullest- answer is contained by the account of creation and expressed in the doctrine of divine Ideas. I would like to trace the lines of that doctrine in Aquinas's corpus as a means of showing how an account of creation at once clarifies and inverts the analysis of natural intelligibility.

Descartes's view of modality is analyzed by contrast to two earlier models: the ancient realist one, defended by Boethius, where possibility and necessity are connected to natural potency, and the modern intensionalist one, which dissociates necessary and possible truths from any ontological foundation, treating them as conceptual, a priori given preconditions for any intellect. The emergence of this view is traced from Gilbert of Poitiers to duns Scotus, Ockham and Suarez. The Cartesian theory of the creation of eternal truths, it (...) is argued, involves a rejection of this idea of absolute conceivability and can be seen as a constructivist view of intelligibility and rationality.

[I] Divine Simplicity: God and His Existence Types of Divine Simplicity Of the properties ascribed to God in Aquinas' natural theology, we may call one sort ...

The nature and content of the thought of Duns Scotus (c. 1266-1308) remains largely unknown except by the expert. This book provides an accessible account of Scotus' theology, focusing both on what is distinctive in his thought, and on issues where his insights might prove to be of perennial value.

In The City of God , XI, 10, St Augustine claims that the divine nature is simple because ‘it is what it has’ . We may take this as a slogan for the Doctrine of Divine Simplicity , a doctrine which finds its way into orthodox medieval Christian theological speculation. Like the doctrine of God's timeless eternality, the DDS has seemed obvious and pious to many, and incoherent, misguided, and repugnant to others. Unlike the doctrine of God's timeless eternality, the (...) DDS has received very little critical attention. The DDS did not originate with Augustine, but I am not primarily concerned with its pedigree. Nor am I concerned to ask how the doctrine interacts with trinitarian speculation. I will have my hands full as it is. In Section I of this paper I shall provide a rough characterization of the DDS, indicate its complexity, and focus on a particular aspect of the doctrine which will exercise us in the remainder of the paper, namely, the thesis that the divine attributes are all identical with each other and with God. In section n I shall discuss Alvin Plantinga's recent objections to Aquinas' version of the DDS. I shall then offer a more detailed presentation of what I take to be Aquinas' version , and recast it in terms of a theory of attributes which is significantly different from Plantinga's . Although the recasting of the doctrine will enable me to rebut Plantinga's objections , it by no means solves all the problems of the DDS. In section vi I shall discuss the chief lingering problem facing a defender of the DDS. (shrink)

Cottingham aims to present Descartes' philosophy in a way that makes "the issues reasonably accessible to students who may be approaching the Cartesian system for the first time". He also aims to do "justice to the complexities of argument involved". There is a potential conflict here: making the issues accessible can lead one to oversimplify them; capturing the complexities of Descartes' thought can cause one to leave inexperienced readers behind. When the conflict arises, Cottingham routinely picks accessibility over philosophical complexity. (...) As a result, his book is not as philosophically sophisticated as other commentaries, such as E. M. Curley's, Margaret Wilson's and Bernard Williams's, but it is a superb introduction to Descartes' philosophy for the uninitiated. Cottingham places Descartes' philosophical ideas within the context of the intellectual climate of his time and shows the interrelations between major elements of Descartes' system, from his epistemology to his view of the physical universe to his physiological and psychological theories. The book's only drawback as an introduction is its limited bibliography. Many who read this book will be inspired to learn more; a more extensive, perhaps topically organized, bibliography would have helped them get started. (shrink)

IN THIS study I shall concentrate on three leading philosophical and theological thinkers of the thirteenth century: Thomas Aquinas, Henry of Ghent, and Godfrey of Fontaines. Of these, Thomas Aquinas is surely the best known. But I have selected these three because their discussions of nonexisting possibles are sufficiently different from one another to illustrate some of the major solutions proposed to this issue at that time.

One of the most difficult and perplexing tenets of classical theism is the doctrine of divine simplicity. Broadly put, this is generally understood to be the thesis that God is altogether without any proper parts, composition, or metaphysical complexity whatsoever. For a good deal more than a millennium, veritable armies of philosophical theologians – Jewish, Christian and Islamic – proclaimed the truth and importance of divine simplicity. Yet in our own time, the doctrine has enjoyed no such support. Among many (...) otherwise orthodox theists, those who do not just disregard it completely explicitly deny it. However, in a couple of recent articles, William E. Mann has attempted to expound the idea of divine simplicity anew and to defend it against a number of criticisms. He even has gone so far as to hint at reaffirming its importance, suggesting that the doctrine may have a significant amount of explanatory power and other theoretical virtue as part of an overall account of the nature of God, by either entailing or in other ways providing for much else that traditional theists have wanted to say about God. In this paper, I want to take a close look at Mann's formulation of the doctrine and at a general supporting theory he adumbrates in his attempt to render more plausible, or at least more defensible, various of its elements and implications. As Mann has made what is arguably the best attempt to defend the doctrine in recent years, I think that such an examination is important and will repay our efforts. (shrink)

The essays in this volume form a commentary on Descartes' _Meditations_. Following the sequence of the meditational stages, the authors analyze the function of each stage in transforming the reader, to realize his essential nature as a rational inquirer, capable of scientific, demonstrable knowledge of the world. There are essays on the genre of meditational writing, on the implications of the opening cathartic section of the book on Descartes' theory of perception and his use of skeptical arguments; essays on the (...) theory of ideas and their role of Descartes' reconstructive analytic method; essays on the proofs for the existence of God, on the role of the will in the formation and malformation of judgments; and the essays on the foundations of the science of extension and on Descartes' account of the union of mind and body.
