It has been argued that St. Thomas Aquinas’s anthropological views fall prey to the problem of “Too Many Thinkers.” The worry, roughly, is that his views entail that I—a human person—am able to think, but that my soul—which is not a human person—is also able to think. Hence, too many thinkers: there are too many ofus having my thoughts. In this paper, I show why this is not a problem for St. Thomas. Along the way, I also address Peter Unger’s (...) argument for substance dualism. (shrink)

Since St. Thomas Aquinas holds that death is a substantial change, a popular current interpretation of his anthropology must be mistaken. According to that interpretation – the ‘survivalist’ view – St. Thomas holds that we human beings survive our deaths, constituted solely by our souls in the interim between death and resurrection. This paper argues that St. Thomas must have held the ‘corruptionist’ view: the view that human beings cease to exist at their deaths. Certain objections to the corruptionist view (...) are also met.

Abstract: There is no such thing as ‘the’ hylemorphic account of personal identity. There are several views that count as hylemorphic, and these views can be grouped into two main families—the corruptionist view, and the survivalist view. The differentiating factor is that the corruptionist view holds that the persistence of the soul is not sufficient for the persistence of the person, while the survivalist view holds that the persistence of the soul is sufficient for the persistence of the person. In (...) this paper, I argue that hylemorphists should prefer the corruptionist view. This project ought to be of interest to anyone working on issues of personal identity, not only because hylemorphic views are historically important, but also because they are currently receiving significant attention in the personal identity literature.

More than twenty years after its original publication, _The Case for Animal Rights _is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

Philosophers of mind have not in general been very attentive to metaphysics. This book is a salutary exception to this general observation. A philosopher of mind—at least the body of her very influential work would be classified by most philosophers as belonging to the philosophy of mind—attempts to ground a theory of the relation between human persons and their bodies in an extended essay on the metaphysics of the natural world. Baker is a materialist : in her book, you and (...) I and everyone we know is a material thing. But then how are we material persons related to our bodies, which are also material things? Unlike many materialists, she rejects the following answer to this question: We are identical with our bodies. The bulk of this review is no more than a summary of her answer to the “person-body question.” My summary will use language very different from hers, since it will rely heavily on the language of parthood, and she is extremely hostile to any attempt to use the concept “part” in connection with her theory. Nevertheless, the use I make of this concept is innocuous, and my representation of her answer to the person-body question is accurate. (shrink)

In this paper, I offer a theory of substance. There are three steps in the argument. First, I present and explain my definition of substance. Second, I argue that the definition yields the right results: that is, my definition rules that (among other things) events and universals, privations and piles of trash, are not substances, but at least some ordinary physical objects are. Third, I defend the definition by rebutting two obvious objections to it.

My wife and I and our three children may stand in various relations: being a family, being a basketball team, and so on. I show that Frege's doctrine of existence, when coupled with this simple point, easily solves the problem of material constitution and blocks the overdetermination argument for eliminativism. It does all this work while providing a plausible and clear reductionistic account of material objects. These seem to be very good reasons for accepting Frege's doctrine of existence.

Roughly, animalism is the doctrine that each of us is identical with an organism. This paper explains and defends a hylemorphic version of animalism. I show how hylemorphic animalism handles standard objections to animalism in compelling ways. I also show what the costs of endorsing hylemorphic animalism are. The paper's contention is that despite the costs, the view is worth taking seriously.

In this paper, I develop an ontological position according to which substances such as you and I have no substantial parts. The claim is not that we are immaterial souls. Nor is the claim that we are “human atoms” co-located with human organisms. It is, rather, that we are macrophysical objects that are, in the relevant sense, simple. I contend that despite initial appearances, this claim is not obviously false, and I defend it by showing how much work it can (...) do. (shrink)

We can start with some science fiction. Here on Earth, I enter the Teletransporter. When I press some button, a machine destroys my body, while recording the exact states of all my cells. This information is sent by radio to Mars, where another machine makes, out of organic materials, a perfect copy of my body. The person who wakes up on Mars seems to remember living my life up to the moment when I pressed the button, and is in every (...) other way just like me. (shrink)

Hylomorphism offers a third way between animalist approaches to personal identity, which maintain that psychology is irrelevant to our persistence, andneo-Lockean accounts, which deny that humans are animals. This paper provides a Thomistic account that explains the intuitive responses to thought experiments involving brain transplants and the transformation of organic bodies into inorganic ones. This account does not have to follow the animalist in abandoning the claim that it is our identity which matters in survival, or countenance the puzzles of (...) spatially coincident entities that plague the neo-Lockean. The key is to understand the human being as only contingently an animal. This approach to our animality is one that Catholics have additional reason to hold given certain views about purgatory, our uniqueness as free and rational creatures, and our having once existed as zygotes.

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

Persons and Bodies develops and defends an account of persons and of the relation between human persons and their bodies. Human persons are constituted by bodies, without being identical to the bodies that constitute them—just as, I argue, statues are constituted by pieces of bronze, say, without being identical to the pieces of bronze that constitute them. The relation of constitution, therefore, is not peculiar to persons and their bodies, but is pervasive in the natural world.

This bold and original work of philosophy presents an exciting new picture of concrete reality. Peter Unger provocatively breaks with what he terms the conservatism of present-day philosophy, and returns to central themes from Descartes, Locke, Berkeley, Hume and Russell. Wiping the slate clean, Unger works, from the ground up, to formulate a new metaphysic capable of accommodating our distinctly human perspective. He proposes a world with inherently powerful particulars of two basic sorts: one mental but not physical, the other (...) physical but not mental. Whether of one sort or the other, each individual possesses powers for determining his or her own course, as well as powers for interaction with other individuals. It is only a purely mental particular--an immaterial soul, like yourself--that is ever fit for real choosing, or for conscious experiencing. Rigorously reasoning that the only satisfactory metaphysic is one that situates the physical alongside the non-physical, Unger carefully explains the genesis of, and continual interaction of, the two sides of our deeply dualistic world. Written in an accessible and entertaining style, while advancing philosophical scholarship, All the Power in the World takes readers on a philosophical journey into the nature of reality. In this riveting intellectual adventure, Unger reveals the need for an entirely novel approach to the nature of physical reality--and shows how this approach can lead to wholly unexpected possibilities, including disembodied human existence for billions of years. All the Power in the World returns philosophy to its most ambitious roots in its fearless attempt to answer profoundly difficult human questions about ourselves and our world. (shrink)

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability (...) of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

_Metaphysics: A Contemporary Introduction_ is for students who have already completed an introductory philosophy course and need a fresh look at the central topics in the core subject of metaphysics. It is essential reading for any student of the subject. This Fourth Edition is revised and updated and includes two new chapters on Parts and Wholes, and Metaphysical Indeterminacy or vagueness. This new edition also keeps the user-friendly format, the chapter overviews summarizing the main topics, concrete examples to clarify difficult (...) concepts, annotated further reading at the end of each chapter, endnotes, and a full bibliography. Topics addressed include: the problem of universals the nature of abstract entities the problem of individuation the nature of modality identity through time the nature of time the nature of parts and wholes the problem of metaphysical indeterminacy the Realism/anti-Realism debate. Wherever possible, Michael J. Loux and Thomas M. Crisp relate contemporary views to their classical sources in the history of philosophy. As experienced teachers of philosophy and important contributors to recent debates, Loux and Crisp are uniquely qualified to write this book. (shrink)

What is a human person, and what is the relation between a person and his or her body? In her third book on the philosophy of mind, Lynne Rudder Baker investigates what she terms the person/body problem and offers a detailed account of the relation between human persons and their bodies. Baker's argument is based on the 'Constitution View' of persons and bodies, which aims to show what distinguishes persons from all other beings and to show how we can be (...) fully material beings without being identical to our bodies. The Constitution View yields answers to the questions 'What am I most fundamentally?', 'What is a person?', and 'What is the relation between human persons and their bodies'? Baker argues that the complex mental property of first-person perspective enables one to conceive of one's body and mental states as one's own. (shrink)
