Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

Hud Hudson presents an innovative view of the metaphysics of human persons according to which human persons are material objects but not human organisms. In developing his account, he formulates and defends a unique collection of positions on parthood, persistence, vagueness, composition, identity, and various puzzles of material constitution. The author also applies his materialist metaphysics to issues in ethics and in the philosophy of religion. He examines the implications for ethics of his metaphysical views for standard arguments addressing the (...) moral permissibility of our treatment of human persons and their parts, fetuses and infants, the irreversibly comatose, and corpses. He argues that his metaphysics provides the best foundation in the philosophy of religion for the Christian doctrine of the resurrection of the body. Hudson addresses a broad range of metaphysical issues, but among his most strikingly original contributions are his defense of the "Partist" view and his argument for the compatibility of Christianity with a materialistic theory of human persons.

The subject of personal identity is one of the most central and most contested and exciting in philosophy. Ever since Locke, psychological and bodily criteria have vied with one another in conflicting accounts of personal identity. Carol Rovane argues that, as things stand, the debate is unresolvable since both sides hold coherent positions that our common sense, she maintains, is conflicted; so any resolution to the debate is bound to be revisionary. She boldly offers such a revisionary theory of personal (...) identity by first inquiring into the nature of persons. Rovane begins with a premise about the distinctive ethical nature of persons to which all substantive ethical doctrines, ranging from Kantian to egoist, can subscribe. From this starting point, she derives two startling metaphysical possibilities: there could be group persons composed of many human beings and muliple persons within a single human being. Her conclusions supports Locke's distinction between persons and human beings, but on altogether new grounds. These grounds lie in her radically normative analysis of the condition of personal identity, as the condition in which a certain normative commitment arises, namely, the commitment to achieve overall rational unity within a rational point of view. It is by virtue of this normative commitment that individual agents can engage one another specifically as persons, and possess the distinctive ethical status of persons. Carol Rovan is Associate Professor of Philosophy at Yale University. Originally published in 1997.

I argue against two popular claims. The first is a descriptive, empirical thesis about the nature of ordinary human experience: ‘each of us constructs and lives a “narrative” . . . this narrative is us, our identities’ (Oliver Sacks); ‘self is a perpetually rewritten story . . . in the end, we become the autobiographical narratives by which we “tell about” our lives’ (Jerry Bruner); ‘we are all virtuoso novelists. . . . We try to make all of our material (...) cohere into a single good story. And that story is our autobiography. The chief fictional char- acter . . . of that autobiography is one’s self’ (Dan Dennett). The second is a normative, ethical claim: we ought to live our lives narratively, or as a story; a ‘basic condition of making sense of ourselves is that we grasp our lives in a narrative’ and have an understanding of our lives ‘as an unfolding story’ (Charles Taylor). A person ‘creates his identity [only] by forming an autobiographical narrative – a story of his life’, and must be in possession of a full and ‘explicit narrative [of his life] to develop fully as a person’ (Marya Schechtman).

In this paper I discuss a number of different relationships between two kinds of obligation: those which have individuals as their subject, and those which have groups of individuals as their subject. I use the name collective obligations to refer to obligations of the second sort. I argue that there are collective obligations, in this sense; that such obligations can give rise to and explain obligations which fall on individuals; that because of these facts collective obligations are not simply reducible (...) to individual obligations; and that collective obligations supervene on individual obligations, without being reducible to them. The sort of supervenience I have in mind here is what is sometimes called ‘global supervenience’. In other words, there cannot be two worlds which differ in respect of the collective obligations which exist in them without also differing in respect of the individual obligations which exist in them.

Precis of my book by this title, for a symposium.

A property, F, is maximal i?, roughly, large parts of an F are not themselves Fs. Maximal properties are typically extrinsic, for their instantiation by x depends on what larger things x is part of. This makes trouble for a recent argument against microphysical superve- nience by Trenton Merricks. The argument assumes that conscious- ness is an intrinsic property, whereas consciousness is in fact maximal and extrinsic.

Derek Parfit claims that, at certain times and places, the metaphysical units he labels *'selves" may be thought of as the morally significant units (I.e., the objects of moral concern) for such things as resource distribution, moral responsibility, commitments, etc. But his concept of the self is problematic in important respects, and it remains unclear just why and how this entity should count as a moral unit in the first place. In developing a view I call *'Moderate Reductionism," I attempt (...) to resolve these worries, first by offering a clearer, more consistent account of what the concept of *'self ' should involve, and second by arguing for why selves should indeed be viewed as moral (and prudential) units. I then defend this view in detail from both *'conservative" and *'extreme" objections. (shrink)

Many philosophers think that, if your “day self” and “night self” are physically, psychologically, and narratively continuous with each other, then they are the same unit of moral concern. But I argue that your day self and night self can share all of these relations and still be different units of moral concern, on the grounds that they can share all of these relations and still be in the circumstances of justice. I then argue that this conception of the scope (...) of morality has revisionary, but ultimately plausible, implications for the morality of self-binding. For example, it implies that your day self and night self have a prima facie duty not to coerce or physically restrain each other in order to get what they want. But it also implies that they are morally permitted to coerce and physically restrain each other much more often, and with respect to many more issues, than, say, you and your friend are. (shrink)

In this paper, I present a new account of akrasia based on the idea that human psychology and self-narrativity are more complex and layered than we have traditionally thought. I begin by arguing that, if we have at least some different beliefs, desires, preferences, etc. in different situations, then we can rationally do what we think, at the time of action, is best for, or from the standpoint of, “part of me” while acting contrary to what we think, at the (...) time of action, is best for, or from the more comprehensive standpoint of, “me.” I then argue that many of us do, in fact, think and act this way in everyday life, and that this kind of action satisfies all the criteria for akrasia. Finally, I briefly argue that on my account of akrasia, akratic actions are not necessarily irrational or blameworthy, though they often will be. (shrink)

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

In this essay I explore the idea that the solution to some important problems of personal identity lies in the philosophy of language: more precisely in the nature of first-person reference. I will argue that the “linguistic solution” is at best partly successful.

According to a view attractive to both metaphysicians and ethicists, every period in a person’s life is the life of a being just like that person except that it exists only during that period. These “subpeople” appear to have moral status, and their interests seem to clash with ours: though it may be in some person’s interests to sacrifice for tomorrow, it is not in the interests of a subperson coinciding with him only today, who will never benefit from it. (...) Or perhaps there is no clash, and a subperson’s interests derive from those of the person it coincides with. But this makes it likely that our own interests derive from those of other beings coinciding with us. (shrink)

Just as there are rational requirements on thought, there are rational requirements on action. This book defends a conception of ethics, and a related conception of human nature, according to which altruism is included among the basic rational requirements on desire and action. Altruism itself depends on the recognition of the reality of other persons, and on the equivalent capacity to regard oneself as merely one individual among many.

Being conscious is intrinsic. Suppose P, a conscious human being, “shrinks” by losing an atom from her left index finger. Suppose that at the very first instant at which P has lost that atom, the atoms that then compose her remain just as they were immediately before “the loss.” This implies—assuming MS for reductio—that, just as those atoms compose a conscious object after the loss, so they composed a conscious object before the loss. Name that latter object ‘the atom-complement’.

Peter Unger's 'problem of the many' has elicited many responses over the past quarter of a century. Here I present a new problem of the many. This new problem, I claim, is resistant to the solutions cunently on offer for Unger's problem.

The Problem of Overlappers is a puzzle about what makes it the case, and how we can know, that we have the parts we intuitively think we have. In this paper, I develop and motivate an overlooked solution to this puzzle. According to what I call the self-making view it is within our power to decide what we refer to with the personal pronoun ‘I’, so the truth of most of our beliefs about our parts is ensured by the very (...) mechanism of self-reference. Other than providing an elegant solution to the Problem of Overlappers, the view can be motivated on independent grounds. It also has wide-ranging consequences for how we should be thinking about persons. Among other things, it can help undermine an influential line of argument against the permissibility of elective amputation. After a detailed discussion and defence of the self-making view, I consider some objections to it. I conclude that none of these objections is persuasive and we should at the very least take seriously the idea that we are to some extent self-made. (shrink)

Hurley here revives a classical idea about rationality in a modern framework, by developing analogies between the structure of personality and the structure of society in the context of contemporary work in philosophy of mind, ethics, decision theory and social choice theory. The book examines the rationality of decisions and actions, and illustrates the continuity of philosophy of mind on the one hand, and ethics and jurisprudence on the other. A major thesis of the book is that arguments drawn from (...) the philosophy of mind may be used to undermine widely-held subjectivist positions in ethics and politico-economic theory. The work is inspired by the philosophies of Wittgenstein and Davidson, but goes on to connect their arguments about interpretation with formal work in decision theory and social choice theory, and with the theory of adjudication.

Introduction In the first four chapters of this book, I develop and defend a monistic account of human persons according to which human persons are highly ...

I argue that we have not only individual reasons for action but also collective reasons for action: reasons which apply to us as a group. I next argue that if we together have a reason to act, then I may have a reason to do my part, but only when others will do theirs. Finally, I argue that collective reasons to do good can never make a difference to what individuals ought to do, but that other kinds of collective reasons (...) can. (shrink)

We consider one of Eric Olson's chief arguments for animalism about personal identity: the view that we are each identical to a human animal. The argument was originally given in Olson's book The Human Animal . Olson's argument presupposes an epistemological premise which we examine in detail. We argue that the premise is implausible and that Olson's defense of animalism is therefore in trouble.

Brian Hedden defends a radical view about the relationship between rationality, personal identity, and time. On the standard view, personal identity over time plays a central role in thinking about rationality, because there are rational norms for how a person's attitudes and actions at one time should fit with her attitudes and actions at other times. But these norms are problematic. They make what you rationally ought to believe or do depend on facts about your past that aren't part of (...) your current perspective on the world, and they make rationality depend on controversial, murky metaphysical facts about what binds different instantaneous snapshots into a single person extended in time. Hedden takes a different approach, treating the relationship between different time-slices of the same person as no different from the relationship between different people. On his account, the locus of rationality is the time-slice rather than the temporally extended agent. This impersonal, time-slice-centric approach to rationality yields a unified approach to the rationality of beliefs, preferences, and actions where what rationality demands of you is solely determined by your evidence, with no special weight given to your past beliefs or actions.

John Hawthorne is widely regarded as one of the finest philosophers working today. He is perhaps best known for his contributions to metaphysics, and this volume collects his most notable papers in this field. Hawthorne offers original treatments of fundamental topics in philosophy, including identity, ontology, vagueness, and causation. Six of the essays appear here for the first time, and there is a valuable introduction to guide the reader through the selection.

Four- Dimensionalism defends the thesis that the material world is composed of temporal as well as spatial parts. This defense includes a novel account of persistence over time, new arguments in favour of the four-dimensional ontology, and responses to the challenges four- dimensionalism faces." "Theodore Sider pays particular attention to the philosophy of time, including a strong series of arguments against presentism, the thesis that only the present is real. Arguments offered in favour of four- dimensionalism include novel arguments based (...) on time travel, the debate between spacetime substantivalists and relationalists, and vagueness. Also included is a comprehensive discussion of the paradoxes of coinciding material objects, and a novel resolution of those paradoxes based on temporal counterpart theory. In conclusion Sider replies to prominent objections to four- dimensionalism, including discussion of the problem of the rotating homogenous disk. (shrink)

Our world is full of composite objects that persist through time: dogs, persons, chairs and rocks. But in virtue of what do a bunch of little objects get to compose some bigger object, and how does that bigger object persist through time? This book aims to answer these questions, but it does so by looking at accounts of composition and persistence through a new methodological lens. It asks the question: what does it take for two theories to be genuinely different, (...) and how can we know whether what seems like metaphysical disagreement is really just semantic disagreement? By offering a framework within which to explore issues of theoretical diversity, this book provides a novel way of thinking about the inter-relationship between composition and persistence. Ultimately, it argues for a new way of thinking about these issues, a way that does not preserve the standard theoretical dichotomies between four-dimensionalist theories on the one hand, and three-dimensionalist theories on the other.

Dion is a full-bodied man. Theon is that part of him which consists of all of him except his left foot. What becomes of Dion and Theon when Dion’s left foot is amputated? Employing the doctrine of sortal essentialism, I defend a surprising answer last defended by Chrysippus: that Dion survives while the seemingly unscathed Theon perishes. For replies to critics, see my publications of 1997 and (especially) 2004.

Could space consist entirely of extended regions, without any regions shaped like points, lines, or surfaces? Peter Forrest and Frank Arntzenius have independently raised a paradox of size for space like this, drawing on a construction of Cantor’s. I present a new version of this argument and explore possible lines of response.
