ABSTRACT In the close to medium future, the life sciences might permit a vast extension of the human life span. I will argue that this is a very desirable development for the individual person. The question whether death is a harm to the dying is irrelevant here. All it takes is that being alive is good for the living person and not being alive is not good for anyone. Thus, living persons who expect to live on happily are rationally required (...) to want to stay alive. Eventual uncertainty whether it will be possible to be happy in the future provides no objection, but rather an incentive to try. This view, however, may be naive in assuming that persons are unchanging entities that exist separately from their psychological information. Objections have been derived from reductionistic views that value our future experiences in a way that declines with time, so that there will be a future point beyond which only negligible value accrues. If we adopt such a view, then we cannot now be concerned to have experiences beyond that point. I argue that these arguments fail to take into account all the reasons we might have to be concerned for the future and all the kinds of such concern that come from them. The adoption of a plausible reductionistic account can arguably weaken our concern for the future and certainly change its quality in important ways. But this provides no objection to the desire to live forever, nor to live at all. (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 virtue of what do things persist through time? Are there criteria of their identities through time? Anti-criterialists say no. One prominent challenge to anti-criterialism comes in two steps. The first step is to show that anti-criterialists are committed specifically to the claim that there are no informative metaphysically sufficient conditions for identity through time. The second step is to show that this commitment yields absurd results. Each step of this challenge is open to objection. However, in what follows, I (...) will refortify this challenge to anti-criterialism by offering new reasons to take each step. (shrink)

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)

Do I have a special reason to care about my future, as opposed to yours? We reject the common belief that I do. Putting our thesis paradoxically, we say that nothing matters in survival: nothing in our continued existence justifies any special self-concern. Such an "extreme" view is standardly tied to ideas about the metaphysics of persons, but not by us. After rejecting various arguments against our thesis, we conclude that simplicity decides in its favor. Throughout the essay we honor (...) Jim Rachels, whose final days exemplified his own unselfish morality as well as the “neutralist” ideal we espouse. As an appendix, we include the last original work to be published by James Rachels, in which he criticizes Sidgwick’s most famous defense of egoism. (shrink)
