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.

After describing the disorder of psychopathy, I examine the theories and the evidence concerning the psychopaths’ deficient moral capacities. I first examine whether or not psychopaths can pass tests of moral knowledge. Most of the evidence suggests that they can. If there is a lack of moral understanding, then it has to be due to an incapacity that affects not their declarative knowledge of moral norms, but their deeper understanding of them. I then examine two suggestions: it is their deficient (...) practical reason or their stunted emotions that are at fault. The evidence supports both explanations. I conclude with an overview of the debate concerning whether they are morally or legally responsible for their actions. (shrink)

The family of theories dubbed ‘luck egalitarianism’ represent an attempt to infuse egalitarian thinking with a concern for personal responsibility, arguing that inequalities are just when they result from, or the extent to which they result from, choice, but are unjust when they result from, or the extent to which they result from, luck. In this essay I argue that luck egalitarians should sometimes seek to limit inequalities, even when they have a fully choice-based pedigree (i.e., result only from the (...) choices of agents). I grant that the broad approach is correct but argue that the temporal standpoint from which we judge whether the person can be held responsible, or the extent to which they can be held responsible, should be radically altered. Instead of asking, as Standard (or Static) Luck Egalitarianism seems to, whether or not, or to what extent, a person was responsible for the choice at the time of choosing, and asking the question of responsibility only once, we should ask whether, or to what extent, they are responsible for the choice at the point at which we are seeking to discover whether, or to what extent, the inequality is just, and so the question of responsibility is not settled but constantly under review. Such an approach will differ from Standard Luck Egalitarianism only if responsibility for a choice is not set in stone—if responsibility can weaken then we should not see the boundary between luck and responsibility within a particular action as static. Drawing on Derek Parfit’s illuminating discussions of personal identity, and contemporary literature on moral responsibility, I suggest there are good reasons to think that responsibility can weaken—that we are not necessarily fully responsible for a choice for ever, even if we were fully responsible at the time of choosing. I call the variant of luck egalitarianism that recognises this shift in temporal standpoint and that responsibility can weaken Dynamic Luck Egalitarianism (DLE). In conclusion I offer a preliminary discussion of what kind of policies DLE would support. (shrink)

Phineas Gage’s story is typically offered as a paradigm example supporting the view that part of what matters for personal identity is a certain magnitude of similarity between earlier and later individuals. Yet, reconsidering a slight variant of Phineas Gage’s story indicates that it is not just magnitude of similarity, but also the direction of change that affects personal identity judgments; in some cases, changes for the worse are more seen as identity-severing than changes for the better of comparable magnitude. (...) Ironically, thinking carefully about Phineas Gage’s story tells against the thesis it is typically taken to support. (shrink)

Current discussions on social cognition, empathy, and interpersonal understanding are largely built on the question of how we recognize and access particular mental states of others. Mental states have been treated as temporally individuated, momentary or temporally narrow unities that can be grasped at one go. Drawing on the phenomenological tradition—on Stein and Husserl in particular—I will problematize this approach, and argue that the other’s experiential states can appear meaningful to us only they are viewed in connection with further, non-simultaneous (...) experiential states of the other. I will focus on the temporal structure of mental states which has received less attention in the available literature. Building a comparison between empathy and music perception, I will argue that approaching the problem of other minds from the point of view of particular mental states is like considering music from the point of view of particular notes.

Abstract: A person who remembers having done something has a belief that she did it from having done it. To have a belief that one did something from having done it is to believe that one did the action on the (causal) basis of having done it, where this belief (in order for one to have it) need not be (causally) based even in part on any contributor to the belief other than doing the action. The notion of a contributor (...) to a belief (as opposed to a mere facilitating cause of the belief) is explicated through a series of examples. The account of having a belief that one did something from having done it is then deployed in criticising Ginet's account of ‘memory connection’, in assessing Martin and Deutscher's causal theory of remembering, in indicating how diachronic justification functions in a nontraditional theory of memory, and in setting forth one type of psychological connectedness which, according to advocates of a psychological continuity theory of personal identity, may be employed (noncircularly) in formulating the theory, and which, according to opponents of the theory, provides a target for criticising the theory.

In this paper, I first consider a famous objection that the standard interpretation of the Lockean account of diachronicity (i.e., one’s sense of personal identity over time) via psychological connectedness falls prey to breaks in one’s personal narrative. I argue that recent case studies show that while this critique may hold with regard to some long-term autobiographical self-knowledge (e.g., episodic memory), it carries less warrant with respect to accounts based on trait-relevant, semantic self-knowledge. The second issue I address concerns the (...) question of diachronicity from the vantage point that there are (at least) two aspects of self—the self of psychophysical instantiation (what I term the epistemological self) and the self of first person subjectivity (what I term the ontological self; for discussion, see Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). Each is held to be a necessary component of selfhood, and, in interaction, they are appear jointly sufficient for a synchronic sense of self (Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). As pertains to diachronicity, by contrast, I contend that while the epistemological self, by itself, is precariously situated to do the work required by a coherent theory of personal identity across time, the ontological self may be better positioned to take up the challenge.

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the other generating (...) the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

1. What is the Problem of Personal Identity?Locke posed the problem of personal identity in one brief question, “What makes the same person?” This formulation is deceptively simple. My aim is to offer a new interpretation of the problem and to suggest a method for finding a solution.Investigations of personal identity are usually cast in terms of finding the criterion for personal identity. Yet talk of criteria is ambiguous. In one sense of the term, the criterion of personal identity would (...) be special evidence for personal identity. According to the second usage, the criterion of personal identity would be that state of affairs for which evidence for personal identity is evidence. We will not be concerned with the first construal. On that reading, the problem of personal identity would be an epistemological issue. But the basic question concerning personal identity, “What is one person?” does not appear to be an epistemological question. (shrink)

In discussing Disembodied Persons we need to confront two problems:A. Under what conditions would we consider that a person was present in the absence of the normal bodily cues?B. Could such circumstances arise?The first question may be regarded as epistemic and the second as metaphysical.

This paper addresses a question concerning psycho­logical continuity, i.e., which features preserve the same psychological subject over time; this is not the same question as the one concerning the necessary and sufficient conditions for personal identity. Marc Slors defends an account of psychological continuity that adds two features to Derek Parfit’s Relation R, namely narrativity and embodiment. Slors’s account is a significant improvement on Parfit’s, but still lacks an explicit acknowledgment of a third feature that I call relationality. Because they (...) are usually regarded as cases of radical discontinuity, I start my discussion from the experiences of psychological disruption undergone by victims of severe violence and trauma. As it turns out, the challenges we encounter in granting continuity to the experiences of violence and trauma victims are germane to those we encounter in granting continuity to the experiences of subjects in non-traumatic contexts. What is missing in the most popular accounts of psychological continuity is an explicit acknowledgment of the links that tie our psychological lives to other subjects. A more persuasive notion of psychological continuity is not only embodied and narrative, as is Slors’s notion, but also explicitly relational. (shrink)

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head. But, wanting to be sure of your mathematical insight, you once again think ‘2 + 2 = 4’, this time really meditating on your thought. Now suppose that you're sitting in an empty movie theatre. The lighting is normal (...) and the screen in front of you is blank. Then at some point an image of a peach is flashed on the screen. The image isn't up there for long. In fact, it's only on the screen for what seems like an instant—just long enough for you to see it. These two scenarios are a bit mundane. But, as I will show, reflection on them can yield significant results concerning the nature of persons and their persistence through time. First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (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)

Brian Garrett claims, in defence of Gaunilo’s Perfect Island and contra Plantinga, that ‘Properly understood, the great-making qualities of an island are maximal’. This article demonstrates that they are not, thus ‘the greatest conceivable island’ remains an incoherent concept and Gaunilo’s parody fails.

Considerations of personal identity bear on John Searle's Chinese Room argument, and on the opposed position that a computer itself could really understand a natural language. In this paper I develop the notion of a virtual person, modelled on the concept of virtual machines familiar in computer science. I show how Searle's argument, and J. Maloney's attempt to defend it, fail. I conclude that Searle is correct in holding that no digital machine could understand language, but wrong in holding that (...) artificial minds are impossible: minds and persons are not the same as the machines, biological or electronic, that realize them.

The paper explores what it could mean to speak of love as involving a delight in ‘the simple actuality’ of another, or, as Buber does, of the ‘touchable’ human being as ‘unique and devoid of qualities’. Developing strands in Merleau-Ponty’s treatment of perception, it is argued that the relation between recognising this as a particular individual and recognising particular qualities in her may be close to the reverse of what might be supposed: a recognition of this distinctive smile being dependent (...) on a recognition of who this is. The fundamental place of particulars, as opposed to kinds, in our thought about those we know and care for is developed in part through a phenomenological treatment of our perception of faces. That treatment is set in a context of the justification of our judgements about who someone is, and is linked with a critique of treatments of proper names of individuals in the spirit of Frege. It is in our speaking to those we know that we find a relation to a particular that is direct—not mediated by a description of its properties—that Russell sought in ‘knowledge by acquaintance’.

This article compares the ability to track individuals lacking mental states with the ability to track intentional agents. It explains why reference to individuals raises the problem of explaining how cognitive agents track unique individuals and in what sense reference is based on procedures of perceptual-motor and epistemic tracking. We suggest applying the notion of singular-files from theories in perception and semantics to the problem of tracking intentional agents. In order to elucidate the nature of agent-files, three views of the (...) relation between object- and agent-tracking are distinguished: the Independence, Deflationary and Organism-Dependence Views. The correct view is argued to be the latter, which states that perceptual and epistemic tracking of a unique human organism requires tracking both its spatio-temporal object-properties and its agent-properties.

The problem of diachronic personal identity is this: what explains why a person P1 at time T1 is numerically identical with a person P2 at a later time T2, even if they are not at those times qualitatively identical? One traditional explanation is the soul theory, according to which persons persist in virtue of their nonphysical souls. I argue here that this view faces a new and arguably insuperable dilemma: either souls, like physical bodies, change over time, in which case (...) the soul theory faces an analogue problem of diachronic soul identity, or souls, unlike physical bodies, do not change over time, in which case the soul theory cannot explain why souls relate to particular bodies over time and so at best only partially explains personal identity. I conclude that the soul theory fares no better than physicalist-friendly accounts of personal identity such as bodily- or psychological-continuity-based views. (shrink)

I defend the claim that bodily continuity is the primary criterion of personal identity by arguing there is an important sense in which it (unlike rival criteria) is a necessary condition of such identity. This claim is shown to be misunderstood in recent discussions because of a confusion of it with the claim that bodily continuity is a sufficient condition of personal identity. In the course of my argument, I criticize williams, Shoemaker, Puccetti, Quinton, Miri, And others.

The view that we are human animals, " animalism ", is deeply unpopular. This paper explains what that claim says and why it is so contentious. It then argues that those who deny it face an awkward choice. They must either deny that there are any human animals, deny that human animals can think, or deny that we are the thinking things located where we are.

Este trabajo examina si la pregunta “¿puede pensar una máquina?” ha sido respondida de manera satisfactoria. La primera sección, justamente, examina el dictum cartesiano según el cual una máquina no puede pensar en principio. La segunda trata sobre una rebelión en contra de Descartes, encabezada por Babbage. A su vez, la tercera describe una segunda rebelión encabezada por Turing. En ambas se examina, primero el lenguaje mentalista/instrumentalista para describir a una máquina programada y segundo, el reemplazo de la pregunta por (...) el Juego de la Imitación. En la cuarta sección sostengo que la evidencia aportada por dicho juego nos devuelve a la pregunta, pese a Turing. Por último, la quinta sección versa sobre cómo la Habitación China de Searle, paradójicamente, apoya el dictum cartesiano, y lo hace porque tal experimento mental se basa en una capacidad mental falible: la introspección. Se concluye que la pregunta acerca de si puede pensar una máquina es derivada de otra pregunta filosófica compleja: la de la naturaleza de lo mental y el problema mente-cuerpo. (shrink)

Survival is the theory that some significant part of man continues after the death of his physical body. This dissertation studies philosophical argumentation of Christians and Buddhists, and analyzes the latest available empirical data, to determine which if any forms of survival are most probable. ;Part I finds insuperable difficulties in the purely materialistic resurrection theory, and in survival of disembodied minds as pure process. To make sense, resurrection must postulate either invisible bodies as conscious carriers of personal identity, or (...) a next world of Berkeleyan or Leibnizian idealism entered at death. ;Part II studies Buddhist views of survival. Early Buddhism proposes the alternatives of perpetual rebirth and transcendent nirvana. Pure Land Buddhism propounds objective idealist heavens accessible both in meditation and at death. Tibetan Buddhism further defends the mind-dependent nature of the intermediate state between rebirths. Thus Buddhism also requires either invisible bodies or an idealist next world. ;Part III examines empirical evidence indicative of survival: claimed memories of former lives; apparitions and out-of-body experiences ; and visions of dead people or other worlds at death . Questionable materials are discarded and evidence is presented with sample cases and experimental results. Alternative hypotheses are adduced to interpret the data. The evidence that NDE's are independent of culture and personality, and that some subjects have experiences while "brain dead," shows the falsity of the mind-brain identity theory, and is strongly indicative of survival. ;Part IV considers survival research as a case history of resistance to counter-paradigmatic scientific theories. Change and conservatism in science prove more dependent on sociological and psychological variables than on objective or logical grounds. The study concludes that at least some consciousnesses survive in ethereal or idealistic states, but broader generalization is dangerous without further empirical studies. (shrink)

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the (...) concept of personhood. By demonstrating that our understanding of personhood is relative to frameworks of understanding based on assumption, the meta-theory states that propositions made about persons are not factual statements, but are, rather, matters of contingency. As such, propositions about persons contain truth-value only within a particular frame of reference that is based on these assumptions. Therefore, the problems that traditionally arise in theories of personal identity -- problems with dualism, the mental criterion, and bodily criterion -- result from a flawed approach to the problem altogether. The conclusion is that it is possible to construct a theory of personal identity, but not the theory of personal identity. (shrink)
