From the time of Locke, discussions of personal identity have often ignored the question of our basic metaphysical nature: whether we human people are biological organisms, spatial or temporal parts of organisms, bundles of perceptions, or what have you. The result of this neglect has been centuries of wild proposals and clashing intuitions. What Are We? is the first general study of this important question. It beings by explaining what the question means and how it differs from others, such as (...) questions of personal identity and the mind-body problem. It then examines in some depth the main possible accounts of our metaphysical nature, detailing both their theoretical virtues and the often grave difficulties they face. The book does not endorse any particular account of what we are, but argues that the matter turns on more general issues in the ontology of material things. If composition is universal--if any material things whatever make up something bigger--then we are temporal parts of organisms. If things never compose anything bigger, so that there are only mereological simples, then we too are simples--perhaps the immaterial substances of Descartes--or else we do not exist at all (a view Olson takes very seriously). The intermediate view that some things compose bigger things and others do not leads almost inevitably to the conclusion that we are organisms. So we can discover what we are by working out when composition occurs. (shrink)

Might it be morally wrong to procreate? David Benatar answers affirmatively in Better Never to Have Been , arguing that coming into existence is always a great harm. I counter this view in several ways. First, I argue against Benatar’s asserted asymmetry between harm and benefit—which would support the claim that any amount of harm in a human life would make it not worth starting—while questioning the significance of his distinction between a life worth starting and one worth continuing. I (...) further contend that his understanding of hedonism and desire-fulfillment theories distorts their implications for the quality of human life; as for objective-list theories, I rebut his critique of their human-centered basis of evaluation. Notwithstanding this multi-tiered challenge to Benatar’s reasoning, I conclude with praise for his work and the intellectual virtues it embodies. (shrink)

Advance directives permit competent adult patients to provide guidance regarding their care in the event that they lose the capacity to make medical decisions. One concern about the use of advance directives is the possibility that, in certain cases in which a patient undergoes massive psychological change, the individual who exists after such change is literally a (numerically) distinct individual from the person who completed the directive. If this is true, there is good reason to question the authority of the (...) directive Ð which is supposed to apply to the individual who completed it, not to someone else. This is `the someone else problem'. After briefly introducing advance directives as a basis for medical decision-making, this paper elaborates `the someone else problem' in the context of severe dementia. The paper then reconstructs the reasoning that leads to this putative problem and exposes the important underlying assumption that we are essentially persons. An alternative view of what we are, one that regards personhood as inessential, is then considered, before several arguments are advanced in favor of that alternative view. The paper next explores implications for advance directives: `The someone else problem' is effectively dissolved, while it is noted that a related problem (one beyond the paper's scope) may persist. A few implications beyond advance directives are also identified. (shrink)

Catholic opponents of abortion and embryonic stem cell research usually base their position on a hylomorphic account of ensoulment at fertilization. They maintain that we each started out as one-cell ensouled organisms. Critics of this position argue that it is plagued by a number of intractable problems due to fission (twinning) and fusion. We're unconvinced that such objections to early ensoulment provide any reason to doubt the coherence of the hylomorphic account. However, we do maintain that a defense of ensoulment (...) at fertilization must deny that we're essentially organisms. (shrink)

Scheffler's paper divides into two parts. In the first, he argues that Parfit's argument from the complex view of personal identity neither can, nor is intended to, establish any moral theory; in particular, it cannot establish utilitarianism. Rather, Parfit's aim must have been simply to weaken our attachment to non-utilitarian theories. In discovering that the only philosophically respectable view of personal identity holds it to consist simply in bodily or psychological continuities and connections, we come to see that the distinctness (...) of persons is a less deep fact than we naively supposed that it was. And this weakens the attraction of moral theories which take the distinctness of persons as fundamental and reject utilitarianism on that account. Scheffler points out that Parfit's argument cannot establish, nor can it be extended to establish, anything stronger than this. For the complex view can only rule out nonutilitarian theories if it simply denies that in any sense persons exist over time. But this view rules out not only non-utilitarian moral theories, but every moral theory. (shrink)

There is a hoary tradition in moral philosophy that assumes we cannot determine which moral theory is acceptable or correct unless we have available a correct theory of human nature, or, in its more modern form, of the person. With such a theory of the person, however, we could at least narrow down the choice among competing ethical theories. A more recent tradition, at least in one of its standard interpretations, agrees it would be necessary to have a correct theory (...) of the person before we could determine an acceptable moral theory, but it denies there is a determinate nature of the person to be captured in such a theory. The plasticity of the person, according to this strand of Marxist theory, rules out the possibility of there being universal moral theory at all. In this paper, I would like to explore a view that treads an intermediate path. It agrees with the Marxist denial that there is a determinate nature of the person, a deep fact of the matter, that can be abstracted from the social matrix and made the subject of a theory of the person. And, it agrees with both traditions that moral theory depends on and embodies a theory of the person. But, by making the problem of arriving at an acceptable view of the person itself something that depends on overall theoretical considerations, including moral ones, the intermediary, view may be able to avoid the type of moral relativism associated with the Marxist view.

Conclusions about the morality of abortion have been thought to receive some support from metaphysical doctrines about persons. The paper studies four instances in which philosophers have sought to draw such morals from metaphysics. It argues that in each instance the metaphysics makes no moral difference, and the manner of failure seems indicative of a general epistemic irrelevance of metaphysics to the moral issue.

Most of the world now accepts the idea, first proposed four decades ago, that death means “brain death.” But the idea has always been open to criticism because it doesn't square with all of our intuitions about death. In fact, none of the possible definitions of death quite works. Death, perhaps surprisingly, eludes definition, and “brain death” can be accepted only as a refinement of what is in fact a fuzzy concept.

We shall find that the metaphysical views offered on behalf of moral conclusions about abortion do nothing in defence of those conclusions. Other disputable assumptions separate each moral conclusion from the invoked metaphysical view. It is the defensibility of the other assumptions that is crucial. No metaphysical view cited on behalf of a moral conclusion substantially advances the argument in favour of the conclusion.

This paper's ?I examines Derek Parfit's main, metaphysical, argument for reductionism about personal identity. ?II considers three possible ethical arguments for reductionism, and suggests a new approach to the question of what matters about personal identity which has to do with the notion of an ethical narrative.

We defend the view that we are not identical to organisms against the objection that it implies that there are two subjects of every conscious state one experiences: oneself and one’s organism. We then criticize animalism —the view that each of us is identical to a human organism—by showing that it has unacceptable implications for a range of actual and hypothetical cases of conjoined twinning : dicephalus, craniopagus parasiticus, and cephalopagus.

We are often faced with choices that involve the weighing of people's lives against each other, or the weighing of lives against other good things. These are choices both for individuals and for societies. A person who is terminally ill may have to choose between palliative care and more aggressive treatment, which will give her a longer life but at some cost in suffering. We have to choose between the convenience to ourselves of road and air travel, and the lives (...) of the future people who will be killed by the global warming we cause, through violent weather, tropical disease, and heat waves. We also make choices that affect how many lives there will be in the future: as individuals we choose how many children to have, and societies choose tax policies that influence people's choices about having children. These are all problems of weighing lives. How should we weigh lives? Weighing Lives develops a theoretical basis for answering this practical question. It extends the work and methods of Broome's earlier book Weighing Goods to cover the questions of life and death. Difficult problems come up in the process. In particular, Weighing Lives tackles the well-recognized, awkward problems of the ethics of population. It carefully examines the common intuition that adding people to the population is ethically neutral - neither a good nor a bad thing - but eventually concludes this intuition cannot be fitted into a coherent theory of value. In the course of its argument, Weighing Lives examines many of the issues of contemporary moral theory: the nature of consequentialism and teleology; the transitivity, continuity, and vagueness of betterness; the quantitative conception of wellbeing; the notion of a life worth living; the badness of death; and others. This is a work of philosophy, but one of its distinctive features is that it adopts some of the precise methods of economic theory (without introducing complex mathematics). Not only philosophers, but also economists and political theorists concerned with the practical question of valuing life, should find the book's conclusions highly significant to their work.

This chapter sets out an intertemporal addition theorem, the exact analog, across the dimension of time, of the interpersonal addition theorem. A premise of the new theorem is the 'principle of temporal good', the exact analog of the principle of personal good. It turns out that the principle of temporal good would, if true, give crucial support to the utilitarian principle. The chapter explains that the principle of temporal good is dubious, and describes how this principle might nevertheless be defended. (...) The defence is metaphysical. It is founded on a disuniting metaphysics of personhood. A complete argument was made out by deducing the principle of temporal good from a disuniting metaphysics. The chapter shows that the principle of temporal good, if true, lends very strong support to the utilitarian principle of distribution. So a chain of argument would have been completed, linking the disuniting metaphysics to the utilitarian principle. (shrink)

If personal identity consists in non-branching psychological continuity, then the sharp breaks in psychological connectedness characteristic of Multiple Personality Disorder implicitly commit psychological continuity theories to a metaphysically extravagant reification of alters. Animalist theories of personal identity avoid the reification of alternate personalities by interpreting multiple personality as a failure to integrate alternative autobiographical memory schemata. In the normal case, autobiographical memory cross-classifies a human life, and in so doing provides access to a variety of interpretative frameworks with their associated (...) clusters of general event memory and episodic memory. Multiples exhibit erratic behavior because they cannot access reliably the intersecting autobiographical memory schemata that permit graceful transitions between social roles, behavioral repertoire and emotional dispositions. Selves, in both normal and certain pathological cases, are best understood as semi-fictional narratives created by human animals to serve their social, emotional and physical needs. (shrink)

Whether morality has rational authority is an open question insofar as we can seriously entertain conceptions of morality and practical reason according to which it need not be contrary to reason to fail to conform to moral requirements. Doubts about the authority of morality are especially likely to arise for those who hold a broadly prudential view of rationality. It is common to think of morality as including various other-regarding duties of cooperation, forbearance, and aid. Most of us also regard (...) moral obligations as authoritative practical considerations. But heeding these obligations appears sometimes to constrain the agent's pursuit of his own interests or aims. If we think of rationality in prudential terms–as what would promote the agent's own interests–we may wonder whether moral conduct is always rationally justifiable. Indeed, we do not need to think of rationality in exclusively prudential terms to raise this worry. The worry can arise even if there are impartial reasons–that is, nonderivative reasons to promote the welfare of others. (shrink)

The philosophical literature on multiple personality has focused primarily on problems about personal identity and psychological explanation. But multiple personality and other dissociative phenomena raise equally important and even more urgent questions about moral responsibility, in particular: In what respect(s) and to what extent should a multiple be held responsible for the actions of his/her alternate personalities? Cases of dreaming help illustrate why attributions of responsibility in cases of dissociation do not turn on putative changes in identity, as some have (...) supposed. Instead, it is argued that traditional criteria of rationality and behavioral control apply also to cases of dissociation. It is noted, however, that one can distinguish different kinds of responsibility in cases of dissociation, and that one is responsible for one's dreams in a different sense from that in which one is responsible for actions one can control and evaluate. It is also argued that in cases of multiple personality it is important to distinguish control over switching of personalities from an alter's control over its own behavior. Moreover, the author considers reasons for thinking that amnesia is less relevant to attributions of responsibility than many have supposed. (shrink)

Ethical theories and theories of the person constrain each other, in that a proposition about the person may be a reason for or against an ethical proposition, and conversely. An important class of such propositions about the person concern the boundaries of the person. These boundaries enclose a person 's defining properties, which constitute his identity. A person 's identity may partly determine and partly be determined by his ethical judgments. An equilibrium between one's identity and one's ethical judgments is (...) the counterpart, at the personal level, of the philosophical ideal of reflective equilibrium between a theory of the person and an ethical theory.

Derek Parfit's “reductionist” account of personal identity (including the rejection of anything like a soul) is coupled with the rejection of a commonsensical intuition of essential self-unity, as in his defense of the counter-intuitive claim that “identity does not matter.” His argument for this claim is based on reflection on the possibility of personal fission. To the contrary, Simon Blackburn claims that the “unity reaction” to fission has an absolute grip on practical reasoning. Now David Lewis denied Parfit's claim that (...) reductionism contravenes common sense, so I revisit the debate between Parfit and Lewis, showing why Parfit wins it. Is reductionism about persons then inherently at odds with the unity reaction? Not necessarily; David Velleman presents a reductionist theory according to which fission does not conflict with the unity reaction. Nonetheless, relying on the distinction between person level descriptions of first-person states and the first-person perspective itself, I argue that Velleman's theory does not eliminate fission-based conflict with the unity reaction.

The paper takes a close look at Derek Parfit’s example of the Nineteenth Century Russian in 'Reasons and Persons'. Parfit presents it as an example which illustrates the moral consequences of adopting his reductionist view of personal identity in a positive light. I argue that things turn out to be more complex than he envisages, and that it might be far more difficult to live in his world than he allows.

ABSTRACT: This essay examines and criticizes a set of Kantian objections to Parfit's attempt in Reasons and Persons to connect his theory of personal identity to practical rationality and moral philosophy. Several of Parfit's critics have tried to sever the link he forges between his metaphysical and practical conclusions by invoking the Kantian thought that even if we accept his metaphysical theory of personal identity, we still have good practical grounds for rejecting that theory when deliberating about what to do. (...) The argument between Parfit and his opponents illuminates broader questions about the relationship between our metaphysical beliefs and ourpractical reasons.RÉSUMÉ: Cet article examine et critique un ensemble d'objections kantiennes à la tentative de Parfit, dans Reasons and Persons, d'ajuster sa théorie de l'identité personnelle à la rationalité pratique et à la philosophie morale. Plusieurs des critiques de Parfit ont essayé de rompre le lien qu'il tisse entre ses conclusions métaphysiques et pratiques en évoquant l'idée kantienne selon -laquelle, même si nous acceptons sa théorie métaphysique de l'identité personnelle, il existe cependant de bonnes raisons pratiques de rejeter cette théorie lorsque nous délibérons à propos de ce que nous devons faire. Le débat entre Parfit et ses adversaires nous éclaire sur un questionnement plus large à propos du rapport entre croyance métaphysique et raison pratique. (shrink)

Next SectionThe personal identity problem expresses the worry that due to disrupted psychological continuity, one person’s advance directive could be used to determine the care of a different person. Even ethicists, who strongly question the possibility of the scenario depicted by the proponents of the personal identity problem, often consider it to be a very potent objection to the use of advance directives. Aiming to question this assumption, I, in this paper, discuss the personal identity problem’s relevance to the moral (...) force of advance directives. By putting the personal identity argument in relation to two different normative frameworks, I aim to show that whether or not the personal identity problem is relevant to the moral force of advance directives, and further, in what way it is relevant, depends entirely on what normative reasons we have for respecting advance directives in the first place.

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.

I distinguish what I call ?minimal narrative? from narrative of the kind that might disclose a person's identity in biography or autobiography. The latter exists in what I call ?the realm of meaning?; a realm in which, in ways I try to make clear, form and content cannot be separated. The realm of meaning is also the realm in which we develop an understanding of what it means to lead a human life lucidly responsive to the defining facts of the (...) human condition and, interdependently with that, our sense of what it means to wrong someone. To show to what degree assumptions about the realm of meaning set the stage for our understanding of what it is to wrong someone, of the nature of biography and autobiography and of what it is to learn morally from someone's example, I detail the conceptual structure of a certain kind of racist perception. The racist's distinction between ?us? and ?them?, is essentially the distinction between lives that are lived in the realm of meaning and lives that are not. Much of moral philosophy, I argue, takes as it starting point a perception of human life that is little different from the racist's perception of the lives of those whom he regards as less than fully human.

Eric Olson argues in The Human Animal that thought-experiments involving body-swapping do not in the end offer any support to psychological continuity theories, nor do they pose any threat to his Biological View. I argue that he is mistaken in at least the second claim.
