Can identity itself be vague? Can there be vague objects? Does a positive answer to either question entail a positive answer to the other? In this paper we answer these questions as follows: No, No, and Yes. First, we discuss Evans’s famous 1978 argument and argue that the main lesson that it imparts is that identity itself cannot be vague. We defend the argument from objections and endorse this conclusion. We acknowledge, however, that the argument does not by itself establish (...) either that there cannot be vague objects or that there cannot be identity statements that are indeterminate for ontic reasons. And we further acknowledge that it does not by itself establish that there cannot be identity statements that are indeterminate in virtue of the existence of vague objects. We then go on to argue that, despite this, one who believes in vague objects cannot endorse Evans’s argument. To establish this we offer supplementary arguments that show that if vague objects exist then identity is vague, and that if identity is vague then vague objects exist. Finally we draw attention to an argument parallel to that of Evans’s, but safer, which can be employed against the putative ontic indeterminacy in identity of vague objects which can be differentiated by identity-free properties.

We are all familiar with judgements about the persistence of people. Furthermore, we tend to structure certain attitudes and practices around such judgements because we think that personal identity matters for the relevant practical concerns. Response‐dependence views try to accommodate that personal identity matters by letting relevant attitudes and practices determine the personal identity relation for a particular person. This paper argues that genuine response‐dependence views are not well positioned to accommodate the connection between personal identity and what matters. Rather, (...) if we accept such a connection, this supports normative‐facts‐first views, according to which relevant normative facts determine personal identity. (shrink)

This paper defends a version of strong conventionalism minus the ontological commitments of that view. It defends the claim that strictly speaking there are no persons, whilst explicating how to make sense of talk that is about (or purportedly about) persons, by appealing to features in common to conventionalist accounts of personal identity. This view has the many benefits of conventionalist accounts in being flexible enough to deal with problem cases, whilst also avoiding the various worries associated with the existence (...) of both persons and human animals occupying the same place at the same time to which conventionalist accounts are committed.

Persons care about their future selves. They reason about their future selves’ interests; they plan for their future selves’ happiness and they worry about their future selves’ suffering. This paper is interested in the interplay between diachronic prudential reason and certain accounts of the metaphysics of personal identity that fall under the broad umbrella ‘conventionalist’. Some conventionalists conclude that under certain conditions there are intractable decisions for there is no fact of the matter regarding whether a person-stage ought (prudentially) to (...) ϕ. This paper will suggest otherwise. These decisions are not intractable if we allow that it is sometimes rational for a person-stage to discount the utility of certain future person-stages. The paper then goes on to explore an alternative position that conventionalists might occupy which does not involve any such discounting: prudential relativism. According to prudential relativism it is impossible to offer a single, correct, answer to the question: should person-stage, P, ϕ at t? For according to prudential relativism there is no stage-independent stance from which to evaluate whether a person-stage ought to ϕ. Yet it is not, for all that, intractable, from P’s perspective, whether or not to ϕ. (shrink)

Many metaphysicians tell us that our world is one in which persisting objects are four-dimensionally extended in time, and persist by being partially present at each moment at which they exist. Many normative theorists tell us that at least some of our core normative practices are justified only if the relation that holds between a person at one time, and that person at another time, is the relation of strict identity. If these metaphysicians are right about the nature of our (...) world, and these normative theorists are right about what justifies our normative practices, then we should be error theorists about the justification of at least some of our core normative practices and in turn, arguably we should eliminate those practices for which justification is lacking. This paper offers a way of resolving the tension between these two views that does not lead into the grips of error theory. It is a way that is amenable to “exceptionists” about persons: those who think there is something special about persons and the first-person perspective; that personhood cannot be explained naturalistically, and the first-person perspective is naturalistically irreducible. The conclusion is thus a conditional: given that one is an exceptionist, an attractive way to resolve this tension is to embrace the view that persons are sui generis ontological kinds. (shrink)

Recent work in personal identity has emphasized the importance of various conventions, or ‘person-directed practices’ in the determination of personal identity. An interesting question arises as to whether we should think that there are any entities that have, in some interesting sense, conventional identity conditions. We think that the best way to understand such work about practices and conventions is the strongest and most radical. If these considerations are correct, persons are, on our view, conventional constructs: they are in part (...) constituted by certain conventions. A person exists only if the relevant conventions exist. A person will be a conscious being of a certain kind combined with a set of conventions. Some of those conventions are encoded in the being itself, so requiring the conventions to exist is requiring the conscious being to be organized in a particular way. In most cases the conventions in question are settled. There is no dispute about what the conventions are, and thus no dispute about which events a person can survive. These are cases where we take the conventions so much for granted, that it is easy to forget that they are there, and that they are necessary constituents of persons. Sometimes though, conventions are not settled. Sometimes there is a dispute about what the conventions should be, and thus a dispute about what events a person can survive. These are the traditional puzzle cases of personal identity. That it appears that conventions play a part in determining persons’ persistence conditions only in these puzzle cases is explained by the fact that only in these cases are the conventions unsettled. Settled or not though, conventions are necessary constituents of persons. (shrink)

According to conventionalist or conativist views about personal-identity, utterances of personal-identity sentences express propositions that are, in part, made true by the conative attitudes of relevant persons-stages. In this paper I introduce assessor relative conativism: the view that a personal-identity proposition can be true when evaluated at one person-stage's context and false when evaluated at another person-stage's context, because person-stages have different patterns of conative attitudes. I present several reasons to embrace assessor relative conativism over its more familiar realizer relative (...) cousin. (shrink)

The Zhuangzi 莊子 depicts persons as surviving their deaths through the natural transformations of the world into very different forms—such as roosters, cart-wheels, rat livers, and so on. It is common to interpret these passages metaphorically. In this essay, however, I suggest employing a “Conventionalist” view of persons that says whether a person survives some event is not merely determined by the world, but is partly determined by our own attitudes. On this reading, Zhuangzi’s many teachings urging us to embrace (...) transformation are not merely a psychological aid for dealing with death, but also serve as a tool for literally surviving it.

Conventionalists hold that the sorts of events that one survives—such as teletransportation, or a brain transplant—is at least partly determined by our attitudes. But if Conventionalism is true, whose attitudes directly determine whether one survives? Do the individual's attitudes do all the work as Private Conventionalists hold, or do the community's attitudes also factor in as Public Conventionalists hold? There has recently been a greater push towards Private Conventionalism, while explicit arguments for Public Conventionalism are difficult to come by. In (...) this paper, I attempt to rectify the situation by presenting my case for Public Conventionalism. (shrink)

ABSTRACT I motivate ‘Origin Conventionalism’—the view that which facts about one’s origins are essential to one’s existence depends partly on our person-directed attitudes. One important upshot is that the view offers a novel and attractive solution to the Nonidentity Problem. That problem typically assumes that the sperm-egg pair from which a person originates is essential to that person’s existence; in which case, for many future persons that come into existence under adverse conditions, had those conditions not been realized, the individuals (...) wouldn’t have existed. This is problematic because it delivers the counter-intuitive conclusion that it’s not wrong to bring about such adverse conditions since they don’t harm anyone. Origin Conventionalism, in contrast, holds that whether a person’s sperm-egg origin is essential to their existence depends on their person-directed attitudes. I argue that this provides a unique and attractive way of preserving the intuition that the actions in the ‘nonidentity cases’ are morally wrong because of the potential harm done to the individuals in question.

On a plenitudinous ontology, in every filled region of spacetime, there is at least one object that’s ‘exactly then and there’; one per each modal profile that the matter in the region satisfies. One of the strongest arguments for plenitude, the “argument from anthropocentrism”, puts pressure on us to accept that members of different communities correctly self-identify under different subject concepts. I explore this consequence and offer an account of selves on which self-determination is both socially and individually variant; we (...) determine our spatiotemporal boundaries, our de re modal properties, and the kind of being that we are. We do this by determining which of many candidate beings has the property of being a self. (shrink)

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)

Do pregnant mothers have fetuses as parts? According to the “parthood view” they do, while according to the “containment view” they don’t. This paper raises a novel puzzle about pregnancy: if mothers have their fetuses as parts, then wherever there is a pregnant mother, there is also a smaller thinking being that has every part of the mother except for those that overlap with the fetus. This problem resembles a familiar overpopulation puzzle from the personal identity literature, known as the (...) “Thinking Parts Problem”, but it’s not merely a special case of that problem. Rather, the fact that late-term fetuses have a mental life of their own makes the Problem of Pregnant Thinkers, as I will call it, a sui generis and especially recalcitrant problem. (shrink)

This paper develops the Diachronic Self-Making View, the view that we are the non-accidentally best candidate referents of our ‘I’-beliefs. A formulation and defence of DSV is followed by an overview of its treatment of familiar puzzle cases about personal identity. The rest of the paper focuses on a challenge to DSV, the Puzzle of Inconstant ‘I’-beliefs: the view appears to force on us inconsistent verdicts about personal identity in cases that we would naturally describe as changes in one’s de (...) se beliefs. To solve this problem, the paper defends the possibility of overlapping people, and addresses a number of objections to this idea. (shrink)

One argument that has been suggested for conventionalism about personal identity is that it captures that certain disagreements about personal identity seem irresolvable, without being committed to the view that these disagreements are merely verbal. In this paper, I will take the considerations about disagreement used to motivate conventionalism seriously. However, I will use them to motivate a very different, novel, and as yet unexplored view about personal identity. This is the view that personal identity is a non-representational concept, the (...) nature of which isn’t to be accounted for in terms of what entity it represents, but its non-representational role. I highlight that we find structurally very similar concerns about disagreement in another philosophical debate, namely in meta-ethics. But, in meta-ethics, such sorts of considerations are, traditionally, thought to support one distinctive view: meta-ethical expressivism, a non-representational view about normative thought and discourse. This suggests that we should take a similar view seriously for personal identity. I also develop what such an unfamiliar view might look like, using expressivism as a template. On this view, judgements about personal identity are plans that regulate who to hold accountable. (shrink)

One reading of the Doctrine of Original Sin has it that we are guilty of a sin committed by Adam, thousands of years ago. Fission theorists account for this by saying that Adam fissioned after he sinned and that each of us is one of his ‘fission successors’. This paper recaps the current discussion in the literature about this theory, arguing that the proposed version does not work for reasons already raised by Rea and Hudson. I then introduce a new (...) version of fission theory that avoids the Rea-Hudson objection. (shrink)

One of the standard approaches to the metaphysics of personal identity has some counter-intuitive ethical consequences when combined with maximising consequentialism and a plausible doctrine about aggregation of consequences. This metaphysical doctrine is the so-called ‘multiple occupancy’ approach to puzzles about fission and fusion. It gives rise to a new version of the ‘utility monster’ problem, particularly difficult problems about infinite utility, and a new version of a Parfit-style ‘repugnant conclusion’. While the article focuses on maximising consequentialism for simplicity, the (...) problems demonstrated apply more widely to a range of ethical views, especially flavours of consequentialism. This article demonstrates how these problems arise, and discusses a number of options available in the light of these problems for a consequentialist tempted by a multiple occupancy metaphysics.

In this paper we argue that reflection on the patterns of practical concern that agents like us exhibit strongly suggests that the same person relation comes in continuous degrees rather than being an all or nothing matter. We call this the SP-degree thesis. Though the SP-degree thesis is consistent with a range of views about personal-identity, we argue that combining desire-first approaches to personal-identity with the SP-degree thesis better explains our patterns of practical concern, and hence gives us reason to (...) endorse such an approach. We then argue that the combination of the SP-degree thesis and the desire-first approach are best modelled by a stage-theoretic view of persistence according to which temporal counterpart relations are non-symmetric relations that come in continuous degrees. Ultimately, we think that the overall appeal of this package of views provides reason to accept the package: reasons that outstrip the reasons we have to endorse any particular member of the package.

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be (...) vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong. (shrink)

Current debate in the metaphysics of time ordinarily assumes that we should be realists about time. Recently, however, a number of physicists and philosophers of physics have proposed that time will play no role in a completed theory of quantum gravity. This paper defends fictionalism about temporal thought, on the supposition that our world is timeless. We argue that, in the face of timeless physical theories, realism about temporal thought is unsustainable: some kind of anti-realism must be adopted. We go (...) on to provide an argument against eliminativism about temporal thought. While it doesn't follow from this argument that fictionalism about temporal thought is true, we suggest that this nonetheless shows that fictionalism should be regarded as the preferred view.

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property possession is not analysed as bundle-membership, as in traditional bundle theories, since accidental properties are not included in the object’s bundle. We have a different story to tell about accidental property possession. This move reaps many benefits. Essential bundle theory delivers (...) a simple theory of the essential properties of material objects; an explanation of how object coincidence can arise; an actual-world ground for modal differences between coincident objects; a simple story about intrinsic properties; and a plausible account of certain ubiquitous cases of causal overdetermination.

According to conventionalist accounts of personal identity, persons are constituted in part by practices and attitudes of certain sorts of care. In this paper, we concentrate on the most well-developed and defended version of conventionalism currently on offer (namely, that proposed by David Braddon-Mitchell, Caroline West, and Kristie Miller) and discuss how the conventionalist appears forced either (1) to accept arbitrariness concerning from which perspective to judge one's survival or (2) to maintain egalitarianism at the cost of making “transfiguring” decisions (...) such as Pascal's Wager rationally intractable. We consider three ways the egalitarian conventionalist could make these choices tractable and show that each one comes at significant cost to the view. We end the paper by considering whether accepting arbitrariness would be a better move for the conventionalist and conclude that, even here, she runs the risk of transfiguring choices being rationally intractable.

This unique anthology of new, contributed essays offers a range of perspectives on various aspects of ontic vagueness. It seeks to answer core questions pertaining to onticism, the view that vagueness exists in the world itself. The questions to be addressed include whether vague objects must have vague identity, and whether ontic vagueness has a distinctive logic, one that is not shared by semantic or epistemic vagueness. The essays in this volume explain the motivations behind onticism, such as the plausibility (...) of mereological vagueness and indeterminacy in quantum mechanics and they offer various arguments both for and against ontic vagueness; onticism is also compared with other, competing theories of vagueness such as semanticism, the view that vagueness exists only in our linguistic representation of the world. Gareth Evans’s influential paper of 1978, “Can There Be Vague Objects?” gave a simple but cogent argument against the coherence of ontic vagueness. Onticism was subsequently dismissed by many. However, in recent years, researchers have become aware of the logical gaps in Evans’s argument and this has triggered a new wave of interest in onticism. Onticism is now widely regarded as at least a coherent view. Reflecting this growing consensus, the present anthology for the first time puts together essays that are focused on onticism and its various facets and it fills in the lacuna in the literature on vagueness, a much-discussed subject in contemporary philosophy.

Pluralists about coincident entities say that distinct entities may be spatially coincident throughout their entire existence. The most pressing issue they face is the grounding problem. They say that coincident entities may differ in their persistence conditions and in the sortals they fall under. But how can they differ in these ways, given that they share all their microphysical properties? What grounds those differences, if not their microphysical properties? Do those differences depend only on the way we conceptualise those objects? (...) Are they primitive facts about reality? Neither option is pleasant for the pluralist, but what else can she say? To respond to the grounding problem, the pluralist should first tell a story about what material objects are. If that story explains how the modal and sortal properties of objects are grounded, in a way that allows for differences between coincident objects, then she has a response to the problem. That is precisely my aim in this paper. (shrink)

There is a connection between moral facts and personal identity facts: morality grounds personal identity. If, for example, old Sally enters a teletransporter, and new Sally emerges, the fundamental question to ask is: is new Sally morally responsible for actions (and omissions) of old Sally? If the moral facts are such that she is morally responsible, then Sally persisted through the teletransporter event, and if not, Sally ceased to exist.
