Lynne Rudder Baker and many others think that paradigmatic instances of one object constituting another—a piece of marble constituting a statue, or an aggregate of particles constituting a living body—involve two distinct objects in the same place at the same time. Some who say this believe in the doctrine of temporal parts; but others, like Baker, reject this doctrine. Such philosophers, whom one might call “coincidentalists”, cannot say that these objects manage to share space in virtue of sharing a temporal part confined to just that place and time. But what can or should coincidentalists say about the nature of constitution? Many have analyzed the relation as one of sharing, “at some level”, all and only the same parts. Most have agreed that such massive part-sharing is at least a central component of and necessary condition for constitution. The heart of Baker’s Persons and Bodies, and its most significant contribution to the development of coincidentalism, is a theory of constitution that makes no appeal to mereology. The leading idea in Baker’s account is, instead, a modal one: objects belonging to constituted kinds are the necessary result of putting objects belonging to appropriate constituting kinds in the right circumstances, circumstances which the constituting objects need not have been in. So putting a piece of man-shaped marble in the right circumstances necessarily results in the existence of a second object, a statue, constituted by the marble; but the piece of marble need not have fallen into these circumstances or any others in which it would constitute a statue.

Mark Johnston’s book, Saving God (Princeton University Press, 2010) has two main goals, one negative and the other positive: (1) to eliminate the gods of the major Western monotheisms (Judaism, Christianity, and Islam) as candidates for the role of “the Highest One”; (2) to introduce the real Highest One, a panentheistic deity worthy of devotion and capable of extending to us the grace needed to transform us from inwardly-turned sinners to practitioners of agape. In this review, we argue that Johnston’s attack on traditional forms of monotheism has less force than his criticism of the “undergraduate atheists” (e.g., Hitchens, Harris, Dawkins); and that his candidate for Highest One is not the greatest possible being, and so could not play the role Johnston casts for it.

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”?

This book addresses two basic questions: What is the proper philosophical analysis of the concept of substance? and What kinds of compound substances are there? The second question is mainly addressed by asking what relations among objects are necessary and sufficient for their coming to compose a larger whole. The first 72 pages of the book contain a short history of attempts to answer the first question, and a brief presentation of the analysis the authors defend at length in their earlier book, Substance Among Other Categories. In the remaining 119 pages, the authors take up the second question. This order of presentation makes sense; but it may help to create a false impression in those who only glance at the first few pages—that this book is just a simplified version of the earlier one, with a little bit of history thrown in. It would be quite unfortunate, however, if very many potential readers get this impression; for it might discourage them from looking closely at the bulk of the book, which is new. The issues discussed in the later chapters are at the center of one of the most lively debates in contemporary metaphysics; and the position Hoffman and Rosenkrantz stake out is appealing and carefully articulated. Their views deserve careful attention from philosophers working on the metaphysics of persistence through time, personal identity, artifact identity, and mereology.

My comments have two parts. I begin by laying out the argument that seems to me to be at the core of Olson’s thinking about human persons; and I suggest a problem with his reasons for accepting one of its premises. The premise is warranted by its platitudinous or commonsensical status; but Olson’s arguments lead him to conclusions that undermine the family of platitudes to which it belongs. Then I’ll raise a question about how Olson should construe the vagueness that would seem to infect the boundaries of human animals.

Let us say that an extended object is “composed wholly of simples” just in case it is an aggregate of absolutely unextended parts spread throughout an extended region—that is, just in case there is a set S such that: every member is a point-sized part of the object, and for every x, x is part of the object if and only if it has a part in common with some member of S. Could a truly extended substance be composed entirely of unextended parts? Reflection upon the fact that it must be at least possible for extended objects to touch one another suggests that the answer to this question is: No.

Chapter Four of Richard Gale’s On the Nature and Existence of God constitutes an ambitious 80-page monograph on the “free will defense” (FWD). Much of Gale’s argument is aimed at Plantinga’s FWD, but the scope of his criticism extends, finally, to all versions. Gale’s main contentions are that: (i) no version of the FWD can get off the ground without the substantive, true conditionals often called “counterfactuals of human freedom” by contemporary Molinists; (ii) the best theory of these conditionals (Gale’s “minimalism”) implies that the Molinists’ conditionals are true (so traditional omniscience requires that God know them, as the Molinists allege that he does); (iii) but Molinism would make God a puppet-master, and incapable of creating free persons after all. Gale concludes that proponents of the FWD must accept that there are contingent truths God does not know. I argue that Gale’s objections to non-Molinist versions of FWD are easily rebutted; but that his criticisms of Molinism have considerably more bite.

Oxford Studies in Metaphysics is the forum for the best new work in this flourishing field. Much of the most interesting work in philosophy today is metaphysical in character: this new series is a much-needed focus for it. OSM offers a broad view of the subject, featuring not only the traditionally central topics such as existence, identity, modality, time, and causation, but also the rich clusters of metaphysical questions in neighbouring fields, such as philosophy of mind and philosophy of science. Besides independent essays, volumes will often contain a critical essay on a recent book, or a symposium that allows participants to respond to one another's criticisms and questions. Anyone who wants to know what's happening in metaphysics can start here. Volume Two begins with a major paper on consciousness by Ned Block. Block examines 'Max Black's Objection to Mind-Body Identity', an argument for a dualism of physical and phenomenal properties, closely related to Jackson's 'knowledge argument'. His extensive exploration of this family of arguments for property dualism includes considerable discussion of John Perry and Stephen White; their responses to Block's paper complete the section on the metaphysics of consciousness.Three papers consider the thesis that the future is, in some sense, 'open'. Eli Hirsch elaborates a view according to which contingent statements about the future can be indeterminate in truth-value, while preserving 'straight logic', including a principle of bivalence. Peter Forrest defends a sort of 'growing block' theory of the passage of time, emphasizing the way such a metaphysics, combined with a truth-maker principle, can provide an analysis of natural necessity. Trenton Merricks presents a trenchant and original criticism of the 'growing block' theory of time.The volume continues with a group of papers on problems of ontology. Thomas Hofweber's paper, defending nominalism from the objection that there are 'inexpressible' properties and propositions, won the first annual Oxford Studies in Metaphysics Younger Scholar Prize. The papers by Phillip Bricker and Michael Loux examine a couple of deep divides within ontology. John Hawthorne's paper raises some extremely puzzling questions about the nature of persons, given the ontology needed for Timothy Williamson's theory of vagueness. Hawthorne uses these problems to motivate an alternative style of epistemicism. The final three papers take up several issues in the metaphysics of traditional theism. Michael Bergmann and Jeffrey Brower raise objections to combining a Platonic conception of universals with the doctrine of divine aseity; while Brian Leftow defends a non-Platonic theory of universals - a kind of divine-concept nominalism. Hud Hudson suggests that contemplation of the possibility of higher dimensions opens up new avenues in theodicy.

Description: Since its inception, the discussion surrounding Open Theism has been dominated by polemics. On crucial philosophical issues, Openness proponents have largely been devoted to explicating the underlying framework and logical arguments supporting their perspective against competing theological and philosophical perspectives. As a result, very little constructive work has been done on the interconnections between Open Theism and the natural sciences. Given the central place of sciences in today's world, any perspective that hopes to have a broad impact must necessarily address such disciplines in a sustained and constructive manner. To date such engagements from the Openness perspective have been rare. God in an Open Universe addresses this deficiency. This book demonstrates that Open Theism makes a distinctive and highly fruitful contribution to the conversation and constructive work occurring between philosophy, theology, and the sciences. The various essays explore subjects ranging from physics to prayer, from special relativity to divine providence, from metaphysics to evolution, and from space-time to God. All who work at the intersection of theology and the sciences will benefit greatly from these essays that break new ground in this important conversation. Endorsements: ""These essays present what is, in my view, the most promising development in theological thinking in our time, and they do so in a way that is both scholarly and accessible. The book is a must for anyone interested in Christian faith and in science."" -Keith Ward University of Oxford ""Open theists affirm the same openness of the future that religious believers assume when they pray and almost all humans assume when they act. The open future is intuitive; but can it be rigorously defended? God in an Open Universe shows that it can. Open theism has always been an attractive view of God; now it becomes a philosophically rigorous one as well. -Philip Clayton Claremont School of Theology About the Contributor(s): William Hasker is Profesor Emeritus of Philosophy at Huntington University.
