Mentalistic (or Lockean) accounts of personal identity are normally formulated in terms of causal relations between psychological states such as beliefs, memories, and intentions. In this paper we develop an alternative (but still Lockean) account of personal identity, based on phenomenal relations between experiences. We begin by examining a notorious puzzle case due to Bernard Williams, and extract two lessons from it: first, that Williams's puzzle can be defused by distinguishing between the psychological and phenomenal approaches, second, that so far (...) as personal identity is concerned, it is phenomenal rather than psychological continuity that matters. We then consider different ways in which the phenomenal approach may be developed, and respond to a number of objections. That with which the consciousness of this present thinking thing can join itself, makes the same person, and is one self with it, and with nothing else; and so attributes to itself and owns all the actions of that thing, as its own, as far as that consciousness reaches, and no farther; as every one who reflects will perceive.

I am a person. But am I fundamentally and essentially a person? The animalist says no. So must the phenomenal continuity theorist, or so I will argue. Even if, contra animalism, we cannot survive zombification, being a subject of experience is not sufficient for being a person, and phenomenal continuity is not sufficient for our survival as the same person over time. These observations point the way to a positive account of personhood, and provide further insight into the conditions under (...) which literal survival preserves what matters. (shrink)

Here is a question as intriguing as it is brief: what are we? The animalist’s answer is equal in brevity: we are animals. This stark formulation of the animalist slogan distances it from nearby claims—that we are essentially animals, for example, or that we have purely biological criteria of identity over time. Is the animalist slogan—unburdened by modal or criterial commitments—still interesting, though? Or has it lost its bite? In this article we address such questions by presenting a positive case (...) for the importance of animalism and applying that case to recent critiques. (shrink)

The animalist says we are animals. This thesis is commonly understood as the universal generalization that all human persons are human animals. This article proposes an alternative: the thesis is a generic that admits of exceptions. We defend the resulting view, which we call ‘generic animalism’, and show its aptitude for diagnosing the limits of eight case-based objections to animalism.

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)

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.

I go deep into the biology of the human organism to argue that the psychological features and functions of persons are realized by cellular and molecular parallel distributed processing networks dispersed throughout the whole body. Persons supervene on the computational processes of nervous, endocrine, immune, and genetic networks. Persons do not go with brains.

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.

This article examines Derek Parfit's claim in Reasons and Persons that personal identity consists in non-branching psychological continuity with the right kind of cause. It argues that such psychological accounts of our identity fail, but that their main rivals, biological or animalist accounts do not fare better. Instead it proposes an error-theory to the effect that common sense takes us to be identical to our bodies on the erroneous assumption that our minds belong non-derivatively to them, whereas they in fact (...) belong to them derivatively in virtue of belonging to some proper parts of them, namely certain features of their brains. However, these features do not meet another necessary condition of being the subject or owner of our minds: the condition of being “accessible” so that we can attribute our mental states to them in everyday life. There is also the problem of specifying these features more precisely. Nothing meets these two conditions, so we are not identical to anything. This conclusion fits well with Parfit's claim that personal identity is not what matters. But although this negative claim is true, it is suggested that Parfit's positive account of what matters is mistaken: it is rather psychological similarity than psychological continuity/connectedness that matters.

The debate on personal persistence has been characterized by a dichotomy which is due to its still Cartesian framwork: On the one side we find proponents of psychological continuity who connect, in Locke’s tradition, the persistence of the person with the constancy of the first-person perspective in retrospection. On the other side, proponents of a biological approach take diachronic identity to consist in the continuity of the organism as the carrier of personal existence from a third-person-perspective. Thus, what accounts for (...) someone’s persistence over time, is the continuity of his mind on the one hand, and the continuity of his body on the other. In contrast to those views, the paper intends to show that bodily existence represents the basis of selfhood across time, both as the continuity of the experiential self and as the continuity of the autopoietic organism. On the one hand, the lived body conveys a continuity of the self from a first-person perspective, namely a pre-reflective feeling of sameness or a felt constancy of subjectivity. Moreover, an analysis of awakening and sleep shows that there is a continuous transition from full wakefulness to periods of deep sleep which may thus not be regarded as a complete interruption of subjective experience. On the other hand, this constancy converges with the continuity of the organismic life process as conceived from a third-person perspective. Thus, the experiential self of bodily subjectivity and the autopoietic self of the living organism should be regarded as two aspects of one and the same life process. Finally, the lived body also exhibits a specific form of memory that results from the continual embodiment of existence: it consists of all the affinities, capacities and experiences, which a person has acquired throughout his life. Thus, it provides a continuity of self that must not be actively produced through remembering, but rather integrates the person’s entire past in his present being and potentiality. (shrink)

Among your closest associates is a certain human animal – a living, breathing, organism. You see it when you look in the mirror. When it is sick, you don't feel too well. Where it goes, you go. And, one thinks, where you go, it must follow. Indeed, you can make it move through sheer force of will. You bear, in short, an important and intimate relation to this, your animal. So too rest of us with our animals. Animalism says that (...) this relation is nothing short of identity. According to animalists, we do not only coincide with or constitute or inhabit or otherwise hang out with these close associates, our animals: we are them. In this article, I offer an opinionated take on what animalism might be and situate it against contemporary rivals. Then, I outline a simple case for animalism. Finally, I sketch non-standard routes for animalists to take in light of standard challenges. My goal in all of this is to open up some new avenues of animalist thinking. (shrink)

Among the questions to be raised under the heading of “personal identity” are these: “What are we?” (fundamental nature question) and “Under what conditions do we persist through time?” (persistence question). Against the dominant neo-Lockean approach to these questions, the view known as animalism answers that each of us is an organism of the species Homo sapiens and that the conditions of our persistence are those of animals. Beyond describing the content and historical background of animalism and its rivals, this (...) entry explores some of the arguments for and objections to this controversial account of our nature and persistence.

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)

This paper describes the results of our study of folk theories of Americans and Indians, using a brain transplant paradigm. We found significant cultural differences between Americans and Indians. The majority of Americans believed that a brain transplant would result in change in gender behavior whereas the majority of Indians, particularly Brahmin males, believed that a brain transplant would change only the gender behavior of men not women. Qualitative analysis of open-ended responses found that American men believed in the computational (...) model of identity, whereas American women believed in the distributed notion of identity. Among Indians, Brahmin males believed in the biological notion of identity more than any other group. (shrink)

I respond to criticisms by David Mackie of my previous paper on animalism and Lockeanism. I argue that the ‘transplant intuition’, that a person goes where his brain (or cerebrum) goes, is compatible both with animalism and Lockeanism. I give three arguments for this conclusion, two of them developing lines of thought in Parfit's work. However, I accept that animalism and Lockeanism are incompatible, and I go on to consider the difficulties for Lockeanism that this raises. The principal difficulty, concerning (...) the reference of ‘I’, can be met by distinguishing the thinker of an ‘I’‐thought from the reference of an ‘I’‐thought. The reference is always the person thinking the thought, but when the thought is simultaneously that of an animal coincident but non‐identical with that person, there is not a unique thinker. Mackie's criticisms of this view are ineffective. (shrink)

Plans to attempt what has been called a head transplant, a body transplant, and a head-to-body transplant in human beings raise numerous ethical, social, and legal questions, including the circumstances, if any, under which it would be ethically permissible to attempt whole-body transplantation (WBT) in human beings, the possible effect of WBT on family relationships, and how families should shape WBT decisions. Our assessment of many of these questions depends partially on how we respond to sometimes centuries-old philosophical thought experiments (...) about personal identity. As with so much in bioethics, it is impossible to escape, or at least inadvisable to try to bypass, the relevant foundational philosophical concerns. (shrink)

According to philosophers who ground your anticipation of future experiences in psychological continuity and connectedness, it is rational to anticipate the experiences of someone other than yourself, such as a self that is the product of fission or of replication. In this article, I concur that it is rational to anticipate the experiences of the product of fission while denying the rationality of anticipating the experiences of a replica. In defending my position, I offer the following explanation of why you (...) have good reason to anticipate the experiences of your post-fission successor but not your replica: in the former case, you become somebody else, whereas, in the latter case, you are merely replaced by somebody else.

ABSTRACT: There are some problems with Lynne Baker’s constitution account of personal identity that become evident when we consider brain transplant thought experiments and two kinds of rare cases of conjoined twins — the first appears to be one organism but two persons and the second seems to involve two organisms associated with one person. To handle the problems arising from brain transplants, the constitution theorist must admit an additional level of constitution between the organism and the person. To resolve (...) the problems posed by the two kinds of conjoined twins, the constitution theorist must accept that constitution is not always a one-to-one relationship. RESUME: La théorie constitutionnelle de l’identité personnelle de Lynne Baker soulève certains problèmes qui deviennent évidents lorsque l’on considère des expériences de pensée sur des transplantations de cerveaux et deux genres de cas rares de jumeaux conjoints — du premier cas paraît s’ensuivre qu’il y a deux personnes pour un seul organisme alors que du deuxième découle qu’une seule personne existe dans deux organismes. Afin d’expliquer les problèmes qui surviennent avec les transplantations de cerveaux, le théoricien de la constitution doit admettre un niveau de constitution intermédiaire entre l’organisme et la personne. Pour résoudre les problèmes que posent les cas de jumeaux conjoints, le théoricien de la constitution doit accepter que la relation de constitution ne se réalise pas toujours entre deux termes.
