Constitution theorists have argued that due to a difference in persistence conditions, persons are not identical with the animals or the bodies that constitute them. A popular line of objection to the view that persons are not identical with the animals/bodies that constitute them is that the view commits one to undesirable overpopulation, with too many minds and too many thinkers. Constitution theorists are well aware of these overpopulation concerns and have gone a long way toward answering them. However, there (...) is one mental excess worry that remains especially problematic. It is argued here that the worry about too many thoughts, or too many instantiations of mentality in general, remains a serious threat to the constitution view of persons. What exactly the threat is and how it arises is described in detail in Section III. It is then shown that attempts to allay the concern are unsuccessful. I argue, in particular, that appealing to the distinction between derivative and non-derivative instantiation fails to solve the problem. (shrink)

Most analytical philosophers consider that we cannot identify with fictional characters in a literal sense. Specifically, Carroll and Gaut argue that doing so would imply a high degree of irrationality. In this paper I stand for the claim that we can identify with fictional characters thanks to a suspension of disbelief. First, I rely on narrative theories of personal identity to propose a model of how the process of identification might happen in real life. Then, I explain how this model (...) can be adapted to account for the suspension of disbelief that occurs in the special case of identification with fictional characters. (shrink)

Abstract The goal of this chapter is to provide an opinionated overview of the psychologically based account of personal identity and the role of agency within such an account. I describe the essential points of the psychological criterion of personal identity. Then, I discuss how the psychological criterion is related to the Reductionist View of personal identity and whether it is committed to what Derek Parfit names the Extreme Claim. I further discuss how the agency-based views of personal identity can (...) be accommodated within Derek Parfit’s psychologically based view of personal identity. I end the chapter by discussing how an agency-based view, as most notably developed by Christine Korsgaard, could be used to vindicate practical concerns that are traditionally related to personal identity.

Most believe that it is worse for a person to die than to continue to exist with a good life. At the same time, many believe that it is not worse for a merely possible person never to exist than to exist with a good life. I argue that if the underlying properties that make us the sort of thing we essentially are can come in small degrees, then to maintain this commonly-held pair of beliefs we will have to embrace (...) an implausible sort of evaluative hypersensitivity to slight nonevaluative differences. Avoidance of such hypersensitivity pressures us to accept that it can be worse for merely possible people never to exist. If this conclusion is correct, then the standard basis for giving no or less priority to merely possible persons would disappear (i.e., that things cannot be better or worse for them). Though defenders of Person-Affecting Views and their opponents may still disagree in theory, they could arrive at the same answers to many monumentally important practical questions. (shrink)

Personal identity deals with the many philosophical questions about ourselves that arise by virtue of our being people. The most frequently discussed is what it takes for a person to persist through time. Many philosophers say that we persist by virtue of psychological continuity. Others say that our persistence is determined by brute physical facts, and psychology is irrelevant. In choosing among these answers we must consider not only what they imply about who is who in particular cases, both real (...) and imaginary, but also their implications about our metaphysical nature in general.

Human heritable genome editing (HHGE) involves editing the genes of human gametes and/or early human embryos. Whilst ‘identity’ is a key concept underpinning the current HHGE debate, there is a lack of inclusive analysis on different concepts of ‘identity’ which renders the overall debate confusing at times. This paper first contributes to reviewing the existing literature by consolidating how ‘identity’ has been discussed in the HHGE debate. Essentially, the discussion will reveal an ontological and empirical understanding of identity when different (...) types of identity are involved. Here, I discuss genetic, numerical, qualitative and narrative and how each of them is relevant in the HHGE context. Secondly, given the different types of identity, the paper explores how we could navigate these different interpretations of identity in a way that promotes an inclusive and informed discussion between primary stakeholders and the general public in the HHGE debate. Here, I argue for and refine a multi-faceted concept of identity as a suitable framework for discussing the ethical and societal implications of HHGE because it not only could integrate different understandings of identity but also highlight the interconnectedness between these different understandings.

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)

Bishop Butler objected to Locke's theory of personal identity on the grounds that memory presupposes personal identity. Most of those sympathetic with Locke's account have accepted Butler's criticism, and have sought to devise a theory of personal identity in the spirit of Locke's that avoids Butler's circularity objection. John McDowell has argued that even the more recent accounts of personal identity are vulnerable to the kind of objection Butler raised against Locke's own account. I criticize McDowell's stance, drawing on a (...) distinction introduced by Annalisa Coliva between two types of immunity to error through misidentification. (shrink)

Many philosophers working on personal identity and ethics say that personal identity is constituted by stories: narratives people tell or would tell about their lives. Most of them also say that this is personal identity in the ‘characterization sense’, that it is the notion people in ordinary contexts are interested in, and that it raises the ‘characterization question’. I argue that these claims are inconsistent. Narrativists can avoid the incompatibility in one of two ways: They can concede that their view (...) is not about the constitution but the epistemology of personal identity. Or they can say that it is not about personal identity at all. (shrink)

It has often been claimed that orthodox thinking about personal identity undermines the moral authority of advance directives in dementia by implying that the signer of the directive is numerically different from the severely demented patient. This is the ‘identity problem'. I introduce the problem, outline some well‐known solutions, and explain why they might be deemed unattractive. I then propose an alternative solution. It promises to be compatible with orthodox thinking about personal identity. I discuss three ways in which it (...) might be challenged and find that none is convincing. Personal identity is no bar to the moral authority of advance directives. (shrink)

When does a developing human being acquire moral status? I outline three different positions based on substance ontology that attempt to solve the question by locating some morally salient event in the process of human development question. In the second section, I consider some specific empirical objections to one of these positions, refute them, and then show how similar objections and responses would generalize to the other substance-based positions on the question. The crucial finding is that all the attempts to (...) answer the question that involve substance ontology need to appeal to dispositions. (shrink)

I discuss three topics. First, there is a philosophical connecting thread between several recent trends in the abortion discussion, namely, the issue of our animal nature, and physical embodiment. The philosophical name given to the position that you and I are essentially human animals is “animalism.” In Section II of this paper, I argue that animalism provides a unifying theme to recent discussions of abortion. In Section III, I discuss what we do not find among recent trends in the abortion (...) discussion, namely “the right to privacy.” I suggest some reasons why the right to privacy is conspicuous by its absence. Finally, I address Patrick Lee's claim that the evil of abortion involves “the moral deterioration that the act brings to those who are complicit in it, and to the culture that fosters it.”. (shrink)

Animalism in its basic form is the view that we are animals. Whether it is a thesis about anything else – like what the conditions of our persistence through time are or whether we're wholly material things – depends on the facts about the persistence conditions and ontology of animals. Thus, I will argue, there are different varieties of animalism, differing with respect to which other theses are taken in conjunction with animalism in its basic form. The different varieties of (...) animalism vary in credibility: some varieties are supported by arguments that are irrelevant to others, and some varieties are susceptible to objections that others can resist. Adequately distinguishing between varieties of animalism is thus an important preliminary to assessing them. In this paper, I'll present and argue for a taxonomy of the most distinctive varieties. (shrink)

This paper defends a hylomorphic version of animalism according to which human persons survive as immaterial, bodiless animals after death. According to the hylomorphism under consideration, human persons have souls that survive death, and according to the animalism under consideration, human persons are necessarily animals. One might think this implies that human persons don't survive their deaths since if they were to survive their deaths, they would be immaterial animals after death, but necessarily animals are material. This paper shows that (...) the hylomorphic animalist can overcome this problem in a way that respects the intuition that animals are material. In addition, the paper defends the hylomorphic animalist survivalist from the objection that her view introduces an insoluble mereological puzzle. (shrink)

One of the most popular and enduring approaches to indeterminacy phenomena (e.g., vagueness) over the past several decades has been some form or another of supervaluationism. I argue that supervaluationism is inadequate as a model of indeterminacy: There is an entire class of examples of indeterminacy, characterized by a common “branching” structure, that cannot be modeled in the way supervaluationism proposes. I demonstrate my conclusion explicitly with respect to two specific examples—indeterminate personal identity and indeterminate reference—showing how supervaluationism can model (...) neither. Importantly, my arguments apply to both traditional “semantic” and more recent “metaphysical” versions of supervaluationism. (shrink)

This paper will argue that there are no people. Let me summarize the argument. In part II of what follows, I argue that if identity isn't what matters in survival, psychological connectedness isn't what matters either. Psychological connectedness, according to Derek Parfit, is the 'holding of particular direct psychological connections,' for example, when a belief, a desire, or some other psychological feature continues to be had ; psychological connectedness consists in two other relations—resemblance plus a cause that produces it. For (...) our purposes, to say of a relation that it is 'what matters in survival' is to say that it carries the burden of responsibility, remorse, and regret for past misdeeds; and that it is what makes rational the anticipation of, and the special hopes and fears we have about, our own future experiences. A consequence of II is that if identity isn't what matters in survival, either something other than psychological connectedness is what matters or nothing matters. (shrink)

The claim that selves are narratively constituted has attained considerable currency in both analytic and continental philosophy. However, a set of increasingly standard objections to narrative identity are also emerging. In this paper, I focus on metaphysically realist versions of narrative identity theory, showing how they both build on and differ from their neo-Lockean counterparts. But I also argue that narrative realism is implicitly committed to a four-dimensionalist, temporal-parts ontology of persons. That exposes narrative realism to the charge that the (...) narratively constituted self, on the one hand, and the self that is the object of much of our everyday self-reference and self-experience, on the other, can't be the same thing. This conclusion may well force narrativists to abandon metaphysical realism about narrative selves—which, in turn, may leave the invocation of ‘narrativity’ as identity-constituting somewhat under-motivated. (shrink)

The concepts of philosophy and imaginative literature have unclear boundaries and blurred edges; they can hardly be defined essentially in any fruitful manner. But we can talk of indicators of a text being philosophical or literary. The concepts of philosophy and literature are contestable. Further, there are no clear‐cut signs of cognitive progress in philosophy and literature. It is also far from certain that there are any philosophical or literary truths. Actually, works of philosophy and literature deal more in possibilities (...) than in actualities. In addition, fictional narratives play an important role in both philosophical and literary texts. Moreover, philosophy and literature share a tendency to thematize themselves, reflect on themselves. If, however, argumentation were to disappear entirely from all philosophical texts, while every literary text is dominated by argumentative discourse, then the concepts of literature and philosophy would become almost devoid of content. Despite this, there is no gap between philosophy and imaginative literature. (shrink)

When is there no fact of the matter about a metaphysical question? When multiple candidate meanings are equally eligible, in David Lewis's sense, and fit equally well with ordinary usage. Thus given certain ontological schemes, there is no fact of the matter whether the criterion of personal identity over time is physical or psychological. But given other ontological schemes there is a fact of the matter; and there is a fact of the matter about which ontological scheme is correct.

Let thin properties be properties shared by coincident entities, e.g., a person and her body, and thick properties ones that are not shared. Thick properties entail sortal properties, e.g., being a person, and the associated persistence conditions. On the first account of realization defined here, the realized property and its realizers will belong to the same individual. This restricts the physical realizers of mental properties, which are thick, to thick physical properties. We also need a sense in which mental properties (...) can be realized in thin physical properties shared by a person and her body. Defining this in turn requires defining a sense in which the instantiations of sortal properties and of thick properties are realized in micro‐structural states of affairs. A fourth notion of realization is needed to allow for the possibility of coincident entities that share a sortal property, e.g., coincident persons. (shrink)

Argues against the rationality of self-concern. Non-instrumental interest in my own well-being is not justified by the fact that it is mine. This follows from the metaphysics of first-person thought, as thought about the object of immediate knowledge. The argument leaves room for rational self-interest as a form of self-love that is justified, like love for others, by the fact of our shared humanity.

In ‘Narrative and Personal Identity’, Mark Schroeder defends an important and exciting account of personal identity. This account starts from insights he finds in Locke and Frankfurt, but moves beyond them in ways that complicate and improve their respective notions of personhood and agency. I argue that he nonetheless retains too much from the views he rejects, especially an undue emphasis on the role of agency in personal identity and an impoverished picture of our embodiment. This paper explains the ways (...) I think Schroeder does not go far enough, and offers an account that takes his insights a step further. (shrink)

Some theists have adopted materialism for human persons. They associate this metaphysics with their belief in resurrection and focus on problems arising from personal identity, temporal gaps or material constitution, but, in this paper, I argue that being a materialist for human persons leads to an epistemological problem regarding our knowledge of God’s life. The only way to avoid this problem is to choose a particular materialist metaphysics for human persons, that is, a constitution theory that emphasizes the irreducibility of (...) the first-person perspective.

We examine the philosophical and ethical issues associated with conjoined twins and their surgical separation. In cases in which there is an extensive sharing of organs, but nevertheless two distinguishable functioning brains, there are a number of philosophical and ethical challenges. This is because such conjoined twins: 1. give rise to puzzles concerning our identity, about whether we are identical to something psychological or biological;2. force us to decide whether what matters from an ethical point of view is the biological (...) life of our organisms or the existence of our consciousness or mind; 3. raise questions concerning when, if ever, it is morally acceptable to sacrifice one of us to save another;4. force us to reflect on the conditions for ownership of organs and the justification of removal of organs for transplantation which causes the death of the donor; 5. raise questions about who should take decisions about life-risking treatments when this cannot be decided by patients themselves.We examine and suggest answers to these questions.

What happens to a person in a case of fission? Does it survive? Does it go out of existence? Or is the outcome indeterminate? Since each description of fission based on the persistence conditions associated with our ordinary concept of a person seems to clash with one or more platitudes of common sense about the spatiotemporal profile of macroscopic objects, fission threatens the common-sense conception of persons with inconsistency. Standard responses to this paradox agree that the common-sense conception of persons (...) is unstable, differing over which part of the conception requires revision. I will show that this entrenched view of fission is not compulsory. I will develop a solution to the paradox that maintains the consistency of the common-sense conception of persons on the basis of an ontology of persons and other ordinary objects as double-layered compounds. Each of various descriptions of the outcome of personal fission is compatible with principles about the spatiotemporal profile of persons, because the descriptions and the principles manifest different perspectives on persons and are made true or false by different ontological components of the latter. What holds for the fission of persons, holds for the fission of other kinds of objects. (shrink)

Four-dimensionalists offer a unified picture of various puzzles about identity over time, including the puzzle of fission, the puzzle of constitution and the puzzle of undetached parts. What unifies the four-dimensionalist approaches to these puzzles is the possibility of temporal overlap—the possibility for distinct continuants to share a common temporal part, or stage. I claim that the unified picture is inconsistent, if there are informative criteria of identity over time. I will show that while temporal overlap is compatible with four-dimensionalist (...) criteria of diachronic composition, temporal overlap is incompatible with any four-dimensionalist criteria of diachronic identity.

: A key consideration in favour of animalism—the thesis that persons like you and me are identical to the animals we walk around with—is that it avoids a too many thinkers problem that arises for non-animalist positions. The problem is that it seems that any person-constituting animal would itself be able to think, but if wherever there is a thinking person there is a thinking animal distinct from it then there are at least two thinkers wherever there is a thinking (...) person. Most find this result unacceptable, and some think it provides an excellent reason for accepting animalism. It has been argued, however, that animalists face an analogous problem of too many thinkers, the so-called corpse problem, as they must accept both 1) that we are distinct from our bodies, as our bodies can and we cannot persist through death as corpses and 2) that our bodies can think. I argue that the best reasons animalists have for accepting the two claims that generate the distinctness part of the problem double up as reasons to reject the claim that our bodies can think, and vice versa. I argue further that Lockeans cannot similarly get around their problem of too many thinkers. (shrink)

It seems plausible that (i) how much punishment a person deserves cannot be affected by the mere existence or nonexistence of another person. We might have also thought that (ii) how much punishment is deserved cannot increase merely in virtue of personal division. I argue that (i) and (ii) are inconsistent with the popular belief that, other things being equal, when people culpably do very wrong or bad acts, they ought to be punished for this—even if they have repented, are (...) now virtuous, and punishing them would benefit no one. Insofar as we cannot deny (i), we are either forced to abandon the popular belief in desert, or else allow that personal division could, as I put it, “multiply desert.” Some may not find the latter, considered by itself, troubling. But I argue that the thesis that division multiplies desert faces a potentially serious problem, which arises in the context of personal fusion. It is difficult to see how to maintain a particular family of desert views in light of the cases here presented. (shrink)

Most nonhuman animals live on the terms imposed on them by human beings. This condition of being under the mastery of another, or domination, is what republicanism identifies as political unfreedom. Yet there are several problems that must be solved in order to successfully extend republicanism to animals. Here I focus on the question of whether freedom can be a benefit for individuals without a free will. I argue that once we understand the grounds that make freedom a desirable property (...) of choices, we can see how it is appropriate to predicate it of those made by any sentient agent. (shrink)

Nonhuman animals are unable to exert any direct control over the functioning of democratic institutions –the decisions of which, nevertheless, have a pervasive impact on their lives. Their interests are therefore likelier to be set back or unfairly discounted, and their choices are more vulnerable to arbitrary interference. Because of this, some authors have suggested that we ought to redesign our political institutions so that they are more responsive to the interests of animals. We argue that this strategy fails to (...) address the root of the problem, which is animals’ lack of robust political agency. We defend that, should it become technologically feasible, we have a pro tanto obligation, derived from the values that underpin democracy, to uplift, or radically enhance, the political agency of nonhuman animals, so that they can better participate in mass democratic politics, express their interests as they see them, self-organise to defend them, and hold their representatives accountable. Finally, we explain how our argument manages to resist the most important objections against animal enhancement and, in some cases, it does so better than alternative proposals based on the value of animal well-being.

Wild animals probably have net negative lives. Christine Korsgaard rejects the view that we might engineer paradise by redesigning nature and animals so that they have the best possible existences. She believes the genetic changes required would not be identity-preserving, thereby causing animals to cease to exist. I argue, first, that paradise engineering is permissible. Many harms are caused by non-sentient natural entities and processes. Moreover, sentient animals can survive modifications compatible with their psychological persistence over time. Second, we are (...) required to re-engineer nature in order to satisfy animals' right to the resources necessary for a reasonable life. (shrink)

ABSTRACTMany philosophers say that the nature of personal identity has to do with narratives: the stories we tell about ourselves. While different narrativists address different questions of personal identity, some propose narrativist accounts of personal identity over time. The paper argues that such accounts have troubling consequences about the beginning and end of our lives, lead to inconsistencies, and involve backwards causation. The problems can be solved, but only by modifying the accounts in ways that deprive them of their appeal.

In this article I attempt to show conclusively that the apparent intrinsic difference between causing collateral damage and directly attacking innocents is an illusion. I show how eleven morally irrelevant alterations can transform an apparently permissible case of harming as a side-effect into an apparently impermissible case of harming as a means. The alterations are as obviously irrelevant as the victims’ skin colour, and consistently treating them as relevant would have unacceptable implications for choices between more and less harmful ways (...) of securing greater goods. This shows not only how the principles philosophers have proposed for distinguishing between these cases cannot withstand scrutiny, but how we can be sure that there are no relevant differences yet to be discovered. I conclude by considering reasons to think that there are deontological constraints against harming, but that they apply just as forcefully against collateral harms as they do against intended harms.

In his book, Eric Olson (2007) makes some criticisms of a response to the problem of the thinking animal (also called the ‘too many minds’ or ‘too many thinkers’ problem) which I have offered, on behalf of the neo-Lockean psychological continuity theorist. Olson calls my proposal ‘personal pronoun revisionism’ (though I am not suggesting any revision). In what follows I shall say what my proposal actually is, defend it and briefly respond to Olson's criticism.

Two of the main contenders in the debate about personal persistence over time are the neo-Lockean psychological continuity view and animalism as defended by Olson and Snowdon. Both are wrong. The position I shall argue for, which I call, following Olson, the hybrid view, takes psychological continuity as a sufficient but, pace the neo-Lockeans, not necessary condition for personal persistence. It sides with the animalist in allowing that mere biological continuity is also sufficient. So I am, in a sense, a (...) psychological continuity theorist. But I am also in a sense, a biological theorist. (shrink)

In this article, I explore difficult and sensitive questions regarding the nature of transgender identity claims and the appropriate medical treatment for those suffering from gender dysphoria. I first analyze conceptions of transgender identity, highlighting the prominence of the wrong-body narrative and its dualist presuppositions. I then briefly argue that dualism is false because our bodily identity is essential and intrinsic to our overall personal identity and explain why a sound, nondualist anthropology implies that gender identity cannot be entirely divorced (...) from sexual identity. Finally, I make the case that arguments in favor of hormonal and surgical treatments for gender dysphoria rest on this mistaken dualist anthropology, and that these treatments therefore give false hope to those suffering from gender dysphoria, while causing irreversible bodily harm and diverting attention from underlying psychological problems that often need to be addressed. I also briefly discuss how these philosophical claims relate to empirical studies on the outcomes of hormonal and surgical treatments for gender dysphoria and to testimonies of transgender individuals who regret having undergone these treatments.

The Problem of Biological Individuality is the problem of how to count organisms. Whilst counting organisms may seem easy, the biological world is full of difficult cases such as colonial siphonophores and aspen tree groves. One of the main solutions to the Problem of Biological Individuality is the Physiological Approach. Drawing on an argument made by Eric Olson in the personal identity debate, I argue that the Physiological Approach faces a metaphysical problem - the ‘Foetus Problem’. This paper illustrates how (...) metaphysics can contribute to debates about organisms in the philosophy of biology. (shrink)

Multiple selves is a conventional assumption in behavioural welfare economics for modelling intrapersonal well-being. Yet an important question is which self has normative authority over others. In this paper, we advance an argument for what we call the ‘ontological approach’ to personal identity in behavioural welfare economics. According to this approach, ethical questions – such as which preference should be granted normative authority over another – can be informed by the ontological criterion of personal persistence, which aims at determining what (...) it takes for an individual to persist from one time to another.

The view to be defended in this paper is intended to be a novel and compelling model of instrumental practical reasoning, reasoning aimed at determining how to act in order to achieve a given end in a certain set of circumstances. On standard views of instrumental reasoning, the end in question is the object of a particular desire that the agent has, a desire which, when combined with the agent’s beliefs about what means are available to him or her in (...) order to satisfy that desire, can cause the formation of an independent desire or intention to engage in the relevant means. One of the main goals in what follows is to show that such views provide an inadequate understanding of instrumental practical reasoning when it comes to the practical lives of agents. We shall proceed as follows. After some background assumptions are outlined in the next section, two important and largely neglected challenges will be raised to any view of instrumental practical reasoning (hereafter IP reasoning) which only countenances the role of end-directed desires and means-end beliefs in the mental economy of agents. In my view, neither of these challenges can be met, or at least not in any straightforward way. Hence the remainder of the paper is devoted to articulating and defending a new approach to understanding the structure of instrumental practical reasoning. The heart of this positive view will involve the addition of a normative belief concerning the desirability of the agent’s end. (shrink)

The Humean theory of motivation remains the default position in much of the contemporary literature in meta-ethics, moral psychology, and action theory. Yet despite its widespread support, the theory is implausible as a view about what motivates agents to act. More specifically, my reasons for dissatisfaction with the Humean theory stem from its incompatibility with what I take to be a compelling model of the role of motivating reasons in first-person practical deliberation and third-person action explanations. So after first introducing (...) some assumptions about the nature of agency in section one, I will turn to articulating and defending this account of motivating reasons in sections two through four of the paper. Section five then provides some background on the Humean theory before I argue directly against it in section six and critically examine the leading arguments for the view in section seven. Given limitations of space, however, I save the task of developing a positive anti-Humean view for another occasion. (shrink)

Plausible assumptions from Cosmology and Statistical Mechanics entail that it is overwhelmingly likely that there will be exact duplicates of us in the distant future long after our deaths. Call such persons “Boltzmann duplicates,” after the great pioneer of Statistical Mechanics. In this paper, I argue that if survival of death is possible at all, then we almost surely will survive our deaths because there almost surely will be Boltzmann duplicates of us in the distant future that stand in appropriate (...) relations to us to guarantee our survival.

ABSTRACT This article defends the following argument: what makes you and I valuable so that it is wrong to kill us now is what we are (essentially). But we are essentially physical organisms, who, embryology reveals, came to be at conception/fertilisation. I reply to the objection to this argument (as found in Dean Stretton, Judith Thomson, and Jeffrey Reiman), which holds that we came to be at one time, but became valuable as a subject of rights only some time later, (...) in virtue of an acquired characteristic. I argue against this position that the difference between a basic, natural capacity and some degree of development of such a capacity is a mere difference in degree, that this position logically implies the denial of equal personal dignity, and that the selection of the required degree of development of a capacity is necessarily arbitrary.

Is the mammalian embryo/fetus a part of the organism that gestates it? According to the containment view, the fetus is not a part of, but merely contained within or surrounded by, the gestating organism. According to the parthood view, the fetus is a part of the gestating organism. This paper proceeds in two stages. First, I argue that the containment view is the received view; that it is generally assumed without good reason; and that it needs substantial support if it (...) is to be taken seriously. Second, I argue that the parthood view derives considerable support from a range of biological and physiological considerations. I tentatively conclude in favour of the parthood view, and end by identifying some of the interesting questions it raises. (shrink)

Many theorists have found the notion of forgiveness to be paradoxical, for it is thought that only the blameworthy can be appropriately forgiven but that the blameworthy are appropriately blamed not forgiven. Some have appealed to the notion of repentance to resolve this tension. But others have objected that such a response is explanatorily inadequate in the sense that it merely stipulates and names a solution leaving the transformative power of repentance unexplained. Worse still, others have objected that such a (...) response cannot succeed because no amount of repentance can render the blameworthy not blameworthy. I argue that this latter objection is based on a mistaken assumption, the acknowledgement of which has the power to resolve the paradox in a way that meets the explanatory adequacy challenge, and, more generally, has significant implications with which any full theory of forgiveness must engage.

Many of those working on moral responsibility assume that "once blameworthy, always blameworthy." They believe that blameworthiness is like diamonds: it is forever. We argue that blameworthiness is not forever; rather, it can diminish through time. We begin by showing that the view that blameworthiness is forever is best understood as the claim that personal identity is sufficient for diachronic blameworthiness. We argue that this view should be rejected because it entails that blameworthiness for past action is completely divorced from (...) the distinctive psychological features of the person at the later time. This is because on none of the leading accounts of personal identity does identity require the preservation of any distinctive psychological features, but merely requires some form of continuity. The claim that blameworthiness is forever should therefore be rejected. We then sketch an account of blameworthiness over time, and consider two objections. (shrink)

Many people believe that the wrongness of killing a person does not depend on factors like her age, condition, or how much she has to lose by dying – a view Jeff McMahan calls the ‘Equal Wrongness Thesis’. This article argues that we should reject the Equal Wrongness Thesis on the basis of the moral equivalence between killing a person and knocking her unconscious.
