It is widely held that the classic reassembly model of resurrection faces intractable problems. What happens to someone if God assembles two individuals at the resurrection which are equally good candidates for being the original person? If two or more people, such as a cannibal and the cannibal’s victim, were composed of the same particles at their respective deaths, can they both be resurrected? If they can, who gets the shared particles? And would an attempt to reassemble a long-gone individual (...) result in a genuine resurrection, or merely an intrinsic duplicate of the original person? In this paper, I argue that the first of these problems has, in effect, been solved by defenders of a rival view; I propose a novel solution to the second problem; and I show that the third can be solved by upgrading the naïve reassembly model to a novel variety of reassembly model.

What are we? Despite much discussion in historical and contemporary philosophy, we have not yet settled on an answer. A satisfactory personal ontology, an account of our metaphysical nature, will be informed by issues in the metaphysics of material objects. In the dissertation, I target two prominent materialist ontologies: animalism, the view that we are numerically identical to human organisms, and constitutionalism, the view that we are constituted by, but not identical to, human organisms. Because of the problems that arise (...) from endorsing these ontologies, I instead advance immaterialism, the view that we are essentially immaterial. In Chapter 2, I discuss how animalists must respond to a widely-discussed metaphysical puzzle, the problem of the many. This puzzle prompts some to endorse revisionary ontologies of material objects, and I argue that the animalist cannot appeal to these revisionary ontologies to solve the puzzle as it arises for personal ontology. In addition, solutions that don’t involve a commitment to revisionary ontology will be unavailable to the animalist: I argue that if animalists make use of non-revisionary solutions to the problem, they must abandon the most successful argument for their view. Absent their most successful argument, animalists will need to motivate the view in some other way. Some new arguments for animalism have been proposed, and I argue that they fail to give us reason to endorse animalism over competing ontologies. Without a strong argument, we should not prefer animalism over the other, more attractive, views. In Chapter 3, I show how constitutionalists face a different problem: explaining how the person is not the very same thing as the human organism, despite sharing the very same parts and occupying the very same physical space. We think that the person and the organism are different things because they have different modal profiles – the human organism can survive permanent loss of psychological life, but the person, presumably, cannot. Constitutionalists must then explain what grounds the difference in modal profiles, but such an explanation is hard to come by. This is an instance of the grounding problem, which is notoriously intractable. While the grounding problem is a well-known challenge to constitutional accounts of objects, I demonstrate that this puzzle is even more threatening when applied to persons. Some “solutions” to the problem fail to solve it at all, and solutions that might get the right result for ordinary objects require accepting that there are a multitude of persons where we ordinarily take there to be only one. We should not accept a personal ontology that requires a commitment to that multitude. I argue that the threat of the grounding problem is so great that we must reject the constitutionalist personal ontology. We will see from these puzzles in personal ontology that materialist solutions are either unsuccessful or yield unacceptable consequences. This should prompt us toward considering, instead, immaterialism. According to immaterialism, persons are not material objects, and the immaterialist can then provide solutions to the puzzles that threatened materialist ontologies. In Chapter 4, I outline these immaterialist solutions and show that the puzzles cannot be reinstantiated successfully against the immaterialist. I then discuss different available varieties of immaterialism and argue in defense of my preferred version. Ultimately, I argue that we are simple, immaterial entities that come into existence at the proper functioning of the brain. Endorsing this view of personal ontology permits us to adequately respond to metaphysical puzzles and retain judgments about persons that should be most important to us. In particular, the immaterialist has the resources to avoid the problem of too many thinkers and retain the judgment that there is exactly one person in circumstances where we take there to be just one. The immaterialist also has the resources to plausibly analyze thought experiments, such as cerebrum-swap cases, that threaten materialist ontologies. All things considered, it remains to be seen which personal ontology has the most evidence in its favor. In the context of debates that arise from material object metaphysics, however, evidence weighs in favor of immaterialism. Materialist personal ontologies are saddled with unacceptable responses to metaphysical puzzles, and endorsing materialism about persons requires taking on a very high cost: Either there are far more of us than we ordinarily take there to be, or there are no persons – far fewer of us than we ordinarily take there to be. Some might argue that these are the only acceptable options, so cost be damned. But we cannot afford to be so cavalier about our personal ontology. Instead, I advance immaterialist solutions to puzzles in personal ontology and propose that, in the interest of saving ourselves and everyone we love, we should seriously consider accounts according to which we are immaterial entities.

According to philosophical orthodoxy, there are informative criteria of identity over time. Anti-criterialism rejects this orthodoxy and claims that there are no such criteria. This paper examines anti-criterialism in the light of recent attacks on the thesis by Matt Duncan, Sydney Shoemaker and Dean Zimmerman. It is argued that those attacks are not successful. Along the way, a novel strategy to defend anti-criterialism against the critics’ most challenging objection is developed. Under-appreciated difficulties for criterialism are also raised which, I claim, (...) there is no obvious way to solve. It is concluded that anti-criterialism may be a much stronger rival to criterialism than is often supposed. (shrink)

Sometimes in philosophy one view engenders another. If you hold the first, chances are you hold the second. But it’s not always because the first entails the second. Sometimes the tie is less clear, less clean. One such tie is between substance dualism and anti-criterialism. Substance dualism is the view that people are, at least in part, immaterial mental substances. Anti-criterialism is the view that there is no criterion of personal identity through time. Most philosophers who hold the first view (...) also hold the second. In fact, many philosophers just assume that substance dualists ought to, or perhaps even have to, accept anti-criterialism. But I aim to show that this assumption is baseless. Substance dualism doesn’t entail, suggest, support, or in any way motivate anti-criterialism, and anti-criterialism confers no benefit on dualism. Substance dualists have no special reason—and, indeed, no good reason at all—to accept anti-criterialism. Or so I shall argue. My aim isn’t to defend substance dualism, nor is it to attack anti-criterialism. My aim is to show that, contrary to a long-standing trend, dualists needn’t be anti-criterialists. Nor, as it will turn out, should they be. (shrink)

In the first part of the paper, I argue that Christians should incorporate the theory of reincarnation into their belief system. The problem of the apparent disproportion between finite human sin and infinite punishment in Hell becomes far more tractable against the background of reincarnation. In the second part of the paper, I address and answer three objections that may be raised against a Christian theory of reincarnation. The first objection is based on the role of memory in identity, the (...) second points to the essential unity of body and soul, and the third revolves around the suggestion that living multiple lives may more easily lead to damnation than to salvation.

Most theists believe that they will survive death. Indeed, they believe that any given person will survive death and persist into an afterlife while remaining the very same person. In light of this belief, one might ask: how—or, in virtue of what—do people survive death? Perhaps the most natural way to answer this question is by appealing to some general account of personal identity through time. That way one can say that people persist through the time of their death in (...) the same way that people persist through time in general. Then the obvious question is: how—or, in virtue of what—do people persist through time in general? Many different answers to this question have been proposed. Some philosophers think that personal identity through time consists in something, such as psychological or biological continuity. They think that there are informative necessary and sufficient conditions—i.e., criteria—for personal identity through time. These philosophers are criterialists. Other philosophers are anti-criterialists. Anti-criterialists believe that people persist through time, but they deny that there are any informative criteria for personal identity through time. In this paper I develop a challenge to anti-criterialism. I begin by spelling out the commitments of anti-criterialism. Then I argue that there are good reasons for anyone to reject anti-criterialism. And then I argue that theists have special reasons to reject anti-criterialism (This is particularly important and noteworthy because a substantial portion of those who defend anti-criterialism are theists. Examples include [but may not be limited to] Trenton Merricks, Richard Swinburne, Joseph Butler, and Thomas Reid). I conclude that there is an informative criterion for personal identity through time and death, even if we haven’t heard of it yet. (shrink)

The paper concerns the metaphysical possibility of life after death. It argues that the existence of a psychological duplicate is insufficient for resurrection, even if psychological continuity suffices for personal identity. That is because our persistence requires immanent causation. There are at most three ways of having life after death: if we are immaterial souls; if we are snatched bodily from our deathbeds; or if there is immanent causation ‘at a distance’ as Zimmerman proposes--but this requires an ontology of temporal (...) parts.

I argue that ensouled animalism—the view that we are identical to animals that have immaterial souls as parts—has a pair of advantages over its two nearest rivals, materialistic animalism and pure dualism. Contra pure dualism, ensouled animalism can explain how physical predications can be literally true of us. Contra materialistic animalism, ensouled animalism can explain how animals can survive death. Furthermore, ensouled animalism has these advantages without creating any problems beyond those already faced by animalism and by belief in souls. (...) However, some animalists, including Eric Olson, think that animals cannot have immaterial parts. I present a sufficient condition for animal parthood that implies animals can have immaterial parts. Ensouled animalism is not only possible, but also doubly attractive. (shrink)

Physicalist Christology is the view that God the Son, in the Incarnation, became identical with the body of Jesus. The goal of this paper is to defend PC from two recent objections. One is that if GS is a physical object, then he cannot have properties had by God. Then, by Leibniz’s law, the incarnate GS cannot be identical with the second Person of the Trinity. The other objection is that PC implies that the incarnate GS did not exist in (...) the interim period between his death and resurrection. PC then leads to the theologically absurd consequence that one of the three Persons of the Trinity did not exist during this period. I argue that the first objection fails because the very same argumentative strategy applies to the Incarnation on any view. As for the second objection, I endorse an animalist theory of death and argue that the incarnate GS continues to exist as a dead person from his death to resurrection. This shows that there is still continuing Trinity of GS during this period. (shrink)

The relationship of minds, bodies, and persons has been a central topic of debate in Western philosophy and theology. This article reviews the ongoing debates about the relationship and nature of bodies, minds, and persons among contemporary Christian analytic philosophers and theologians. The first two parts present some general theological constraints for philosophical theories of persons and describe the basic concepts used (substance, property, supervenience, and physicalism). The views themselves fall into three broad categories. Dualists think that persons are either (...) identical with or partly constituted by non-physical souls. On this view, there are immaterial substances and properties. Hylomorphists maintain that persons are composites of bodies and the souls that inform them. Finally, physicalists claim that there are no immaterial parts to persons. Instead, persons are composed of bodies and brains; the mental properties they have supervene on physical properties.

In this paper, I state the what I call the “problem of life after death,” survey some responses to it, and highlight a way in which the field might progress. Put simply, the problem of life after death is the problem of reconciling the fact that when we die, we will be totally destroyed with the belief that we will exist again at some time after our deaths. Contemporary solutions to the problem have focussed on the “logical” version of this (...) problem. I highlight that the problem would be better thought of as an evidential problem. (shrink)
