What makes someone the same person over time? There are (at least) two ways of understanding this question: A person can be the same in the sense of being very similar to how they used to be (similarity), or they can be the same in the sense of being the same individual (numerical identity). In recent years, several papers have claimed to explore the commonsense notion of numerical identity. However, we suggest here that these researchers have instead been studying similarity. (...) We develop a novel method that uses simple intuitions about objects to illustrate these two notions of “same person”, and then asks which concept applies to instances of personal change. Across 4 studies (N = 2446), we find that these previously documented intuitions are best understood as reflecting judgments about similarity, not identity (Experiments 1 and 2). We then use this method to explore the situations in which participants do perceive a change in numerical identity. We find that when a person's entire brain (Experiments 3 and 4) or soul (Experiment 4) has been replaced with that of another person, the majority of participants judge that numerical identity has changed. However, we also note that a substantial minority of participants denied that identity had changed, opening new questions about the role of the body in intuitive judgments of personal identity.

The increasing number of dementia cases has led to renewed interest in philosophical theories of personal identity, because these patients seem to “drop out” of their own identities in some ways. Philosophical positions that try to account for the phenomenon of identity loss include numerical theories of identity which argue for a psychological or a biological continuity criterion, narrative theories of identity, as well as reflections about different forms of memory, some of which have had influence in modern psychology and (...) in the neurosciences. This special issue brings together current articles by experts in these areas. / Die zunehmende Verbreitung von Demenzerkrankungen hat zu einem erhöhten Interesse an philosophischen Theorien der personalen Identität geführt, da diese Patienten in manchen Hinsichten aus ihrer eigenen Identität „herauszufallen“ scheinen.

In contemporary philosophy, the will is often regarded as a sheer philosophical fiction. In Will as Commitment and Resolve , Davenport argues not only that the will is the central power of human agency that makes decisions and forms intentions but also that it includes the capacity to generate new motivation different in structure from prepurposive desires. The concept of "projective motivation" is the central innovation in Davenport's existential account of the everyday notion of striving will. Beginning with the contrast (...) between "eastern" and "western" attitudes toward assertive willing, Davenport traces the lineage of the idea of projective motivation from NeoPlatonic and Christian conceptions of divine motivation to Scotus, Kant, Marx, Arendt, and Levinas. Rich with historical detail, this book includes an extended examination of Platonic and Aristotelian eudaimonist theories of human motivation. Drawing on contemporary critiques of egoism, Davenport argues that happiness is primarily a byproduct of activities and pursuits aimed at other agent-transcending goods for their own sake. In particular, the motives involved in virtue and in its practice as understood by Alasdair MacIntyre are projective rather than eudaimonist. This theory is supported by analyses of radical evil, accounts of intrinsic motivation in existential psychology, and contemporary theories of identity-forming commitment in analytic moral psychology. Following Viktor Frankl, Joseph Raz, and others, Davenport argues that Harry Frankfurt's conception of caring requires objective values worth caring about, which serve as rational grounds for projecting new final ends. The argument concludes with a taxonomy of values or goods, devotion to which can make life meaningful for us. (shrink)

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.

The topic of this paper is the general thesis that the death of the human organism is what constitutes the death of a person. All admit that when the death of a human organism occurs, in some form or another, this normally does result in the death of a person. But, some maintain, organismic death is not the same thing as personal death. Why? Because, they maintain, despite the fact that persons are associated with a human organism (‘their organism’), they (...) are not identical with their organism, and so they can, at least in principle and perhaps in actuality, die before or after their organism dies. The thesis described above I shall call ‘the two-deaths thesis’ in virtue of the fact that its proponents believe that there are two kinds of death, viz. organismic death and personal death. The opposing thesis, according to which the death of a human organism does constitute the death of a person, I call the ‘one death thesis’. After giving some background remarks in section 2 of this paper, in section 3 I argue that, if we take linguistic usage seriously, neither the two-deaths thesis nor the one-death thesis is true. I argue, rather, that so far as linguistic usage goes it is indeterminate which of them is true. In section 4 I go further and argue that if one accepts a widely held metaphysical view, viz. that the world itself partially determines reference and the extensions of our concepts, then it is plausible that the one-death thesis is true despite the facts about linguistic usage.

The philosophical problem of personal identity has been widely discussed in contemporary analytic philosophy. The disputes over identity throughout time abound in references to thought experiments, excluding any connection to practical problems or to scientific knowledge and biotechnological practices. Nevertheless, some real cases challenge the pure metaphysical formulation of the problem and also show how science has an indubitable impact on the issue of identity. I will discuss the case of approximately 500 children who were appropriated during the most recent (...) Argentinian dictatorship (1976–1983), as well as their restitution thanks to Abuelas de Plaza de Mayo’s fight and certain genetics outcomes. I will examine an alleged notion of genetic identity thought to have stemmed from the restitution phenomenon; and I will argue against some criticisms to that notion departing from contemporary philosophy of biology and philosophy of science. Particularly, I will discuss if a genetic stance of personal individual identity can be considered as supported by contemporary biological knowledge; and if a pluralistic perspective on scientific practice that appraises the role of values allows us to maintain the reference to DNA regarding identity but overcoming aforementioned criticisms.

In this paper, it is our purpose to argue for a processual conception of ill-person- identity. To do so, we will review some of the main answers that philosophy has given to the question of personal identity. We will review certain proposals on how to conceive illness and ill-person-identity, as well. Within the frame of a processual approach to ontology, we will focus on a non-dualistic processual-relational interpretation of biological organisms.

Thought experiments are profitably compared to compasses. A compass is a simple but useful device for determining direction. Nevertheless, it systematically errs in the presence of magnets ...it becomes unreliable near the North Pole, in mine shafts, when vibrated, in the presence of metal ...experts will wish to use the compass as one element in a wider portfolio of navigational techniques. Analogously, thought experiments are simple but useful devices for determining the status of propositions. Sadly, they systematically err under certain (...) conditions and so are best used with sensitivity to their foibles and limited scope (Sorensen, 1992, pp. 288–289). (shrink)

It is thought by some philosophers that certain arguments developed by Peter Strawson in Individuals show that Derek Parfit's claim in Reasons and Persons that experiences can be referred to without referring to persons is incoherent. In this paper I argue that Parfit's claim is not threatened by these arguments.

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.

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of psychological characteristics is (...) required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

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)

‘Transplant’ thought-experiments, in which the cerebrum is moved from one body to another, have featured in a number of recent discussions in the personal identity literature. Once taken as offering confirmation of some form of psychological continuity theory of identity, arguments from Marya Schechtman and Kathleen Wilkes have contended that this is not the case. Any such apparent support is due to a lack of detail in their description or a reliance on predictions that we are in no position to (...) make. I argue that the case against them rests on two serious misunderstandings of the operation of thought-experiments, and that even if they do not ultimately support a psychological continuity theory, they do major damage to that theory’s opponents.

Paul Ricoeur and Marya Schechtman express grave doubts about the acceptability and informativeness of the thought-experiments employed by analytic philosophers (notably Derek Parfit) in the debate about personal identity, and for what appear to be related reasons. I consider their reasoning and argue that their reasons fail to justify their doubts. I go on to argue that, from this discussion of possible problems concerning select thought-experiments, something positive can be learned about personal identity.

Nils-Frederic Wagner takes issue with my argument that influential critics of “transplant” thought experiments make two cardinal mistakes. He responds that the mistakes I identify are not mistakes at all. The mistakes are rather on my part, in that I have not taken into account the conceptual genesis of personhood, that my view of thought experiments is idiosyncratic and possibly self-defeating, and in that I have ignored important empirical evidence about the relationship between brains and minds. I argue that my (...) case still stands and that transplant thought experiments can do damage to rivals of a psychological continuity theory of personal identity like Marya Schechtman’s Person Life View.

The thought-experiment presented by Bernard Williams in 'The self and the future' continues to draw the attention of writers in the debate about personal identity. While few of them agree on what implications it has for the debate, almost all agree that those implications are significant ones. Some have even claimed that it has consequences not only for personal identity, but also concerning the viability of thought-experiment as a method. This paper surveys what these consequences might be at both levels (...) - as a substantive contribution to the debate on identity, and as to what it shows about the usefulness of thought-experiments. It argues ultimately that thought-experiments like Williams's do provide a useful philosophical tool as long as we temper our expectations of them, and that it offers some support to a view of personal identity but one which is at odds with Williams's own view.

In this paper, I attempt to map out the 'logical geography' of the territory in which issues of mental content and of personal identity meet. In particular, I investigate the possibility of combining a psychological criterion of personal identity with an externalist theory of content. I argue that this can be done, but only by accepting an assumption that has been widely accepted but barely argued for, namely that when someone switches linguistic communities, the contents of their thoughts do not (...) change immediately, but only after the person becomes integrated within the new linguistic community. I also suggest that recent work on personal identity, notably by Derek Parfit, has tacitly assumed internalism regarding mental content. I do not intend to argue for either externalism or a psychological criterion. My aim is merely to explicate the issues involved in making them compatible. (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.

In ‘Moral Luck,’ Bernard Williams famously argued that “there is a particularly important species of regret, which I shall call ‘agent-regret,’ which a person can feel only towards his past actions.” Much subsequent commentary has focused on Williams’s claim that agent-regret is not necessarily restricted to voluntary actions, and questioned whether such an attitude could be rationally justified. This focus, however, obscures a more fundamental set of questions raised by Williams’s discussion: what is the role in our moral psychology of (...) evaluative attitudes that relate essentially to past exercises of our agency—occurrences which, by their very nature, cannot be repeated? On a standard conception, regret is directed principally towards actions that resulted from suboptimal deliberation. On this view, the main point of regret is to guide us away from similar poor decisions in the future. But Williams’s key insight in ‘Moral Luck,’ I argue, is that there is a mode of evaluation of one’s past actions and decisions that does not track considerations one could and should have been responsive to at the time, and is for this reason essentially retrospective. From this perspective, the full significance of regret cannot be captured in terms of a disposition to deliberate better in the future. Rather, the particular kind of painful of consciousness of the past embodied in regret amounts to a reflective, and essentially backward-looking, insight into the contingency and finitude of our own agency—that I am a particular person leading a particular life, and that the possibility of leading a different life is now gone forever. I end by making some speculative comments about the intractable question whether it is ultimately good or desirable to be disposed to regret one’s past mistakes. (shrink)

In this article, we consider three metaphysical theories of personal identity: the soul theory, the body theory, and the psychological theory. Clinical cases are discussed as they present conceptual problems for each of these theories. For the soul theory, the case of Phineas Gage, and cases of pedophilic behavior due to a brain tumor are discussed. For the body theory, hypothetical cases of cephalosomatic anastomosis and actual cases of dicephalic parapagus and craniopagus parasiticus are discussed. For the psychological theory, cases (...) of delusions and memory impairments are discussed. After a discussion of all these cases, we conclude that it is very difficult to unequivocally favor one of these theories, yet we argue that this discussion must be based not on abstract armchair speculation, but rather, consideration of real clinical cases.

It is argued here that it is part of our concept of a ‘person’ that persons should be, by its nature, able to endure in time. In no conception of persons as ‘perduring’ entities with different temporal parts for different times, or as sequences of stages in the relation of ‘being a survival of ’ between them, it is possible to make sense of some of our normative intuitions about persons. It is argued also that the traditional psychological theory of (...) personal identity is untenable. Psychological continuity appears to be neither sufficient nor necessary for personal identity. A reasonable conception of persons seems to be either a form of ‘animalism’ where persons are biological organisms, or a theory in which persons are primitive substances, with primitive conditions of identity.

There is an intimate connection between personal identity, prudential concern, and anticipation. But just how close is the connection? In this paper, I develop and motivate phenomenal accounts of both anticipation and prudential concern which suggest that the link between anticipation and personal identity and the one between anticipation and prudential concern is less tight than often assumed. I start by arguing against two influential accounts of anticipation, and present an alternative view based on the notion of phenomenal continuity, which (...) detaches anticipation from identity. Next, I consider the relationship between anticipation and prudential concern and make the case that, here too, there is more space between the two than orthodoxy alleges. A qualified form of anticipation may be sufficient for prudential concern, but anticipation is not necessary for prudential concern. Finally, I argue that prudential concern is grounded in phenomenal continuity, rather than psychological continuity. This secures a close alignment between anticipation and prudential concern and offers a plausible explanation as to why anticipation is a guide to prudential concern. (shrink)

Psychologists and philosophers have recently argued that our concepts of ‘person’ or ‘self’ are plural. Some have argued that we should also adopt a corresponding pluralism about the metaphysics of the self. The aim of this paper is twofold. First, I sketch and motivate an approach to personal identity that supports the inference from facts about how we think about the self to facts about the nature of the self. On the proposed view, the self-concept partly determines the nature of (...) the self. This approach provides new justification for the recent empirical turn in the philosophy of personal identity. Second, I argue that closer examination reveals that the empirical evidence does not in fact support pluralism about the self. Instead, the evidence points toward a model of the self-concept as a complex web of attitudes that is disposed toward integration and unity. I ultimately suggest that this unifying disposition of the self-concept helps ground the existence of a singular self. (shrink)

Panpsychism is the view that all things are associated with consciousness. Panpsychism has a number of significant theoretical implications, with respect to the mind–body problem and other problems in metaphysics. Here I will consider one of its potential practical or ethical implications; specifically, whether, if panpsychism is true, it follows that “we are all one”, in a sense that implies that egoism (understood as bias towards what we normally take to constitute the self or ego) is not only immoral but (...) fundamentally irrational (or imprudent).

It is a startling fact that, despite its long and rich history, the debate about per- sonal identity is far from settled. The present paper examines two deflationary explanations for this: a) the dispute is merely verbal (verbalism); b) there cannot be sufficient justification for preferring one theory of personal identity over the others (epistemicism). As this paper argues, there is evidence that either verba- lism or epistemicism provides a correct account of the personal identity debate.

In this volume, thirteen philosophers contribute new essays analyzing the criteria for personal identity and their import on ethics and the theory of action: it presents contemporary treatments of the issues discussed in Personal Identity, edited by John Perry (University of California Press, 1975).

Eric Olson and David Shoemaker argue that our numerical identity over time is irrelevant to such practical issues as moral responsibility or self-concern. Being the same individual at different moments in time may, in our case, can be seen as the preservation of the relevant biological processes (e.g., according to Olson), while psychological continuity, independent of these processes, may be crucial for such issues. I will defend the view that, contrary to the above authors, any conception of our diachronic identity (...) has ethical implications, at least with regard to the aforementioned issues. My argument has two basic assumptions. (1) The dispute over identity of persons is a dispute over the conditions of our persistence in time as the same individuals, whether we consider being a person as our essential property or not (e.g., Olson maintains the latter). The question is under what conditions I am the same as a particular earlier or later individual. (2) The pronoun “I,” on the other hand, is an essential component of practical reasoning, so also of ethical one. Thus, the debate on the persistence of persons concerns the identity conditions of the individuals to whom/which we refer when planning our future actions, formulating our intentions. My rational self-concern or my moral responsibility for past actions regards the individual to whom the pronoun refers. An additional result of my argument is to undermine the influential strategy of defending positions on our diachronic identity against the charge of controversial ethical implications. It cannot be argued in the case of every such controversy that a given ethical issue only apparently involves our identity, while in fact what is relevant to it is a different relation binding persons at different moments in time.

In this paper, I argue that standard psychological continuity theory does not account for an important feature of what is important in survival—having the property of personhood. I offer a theory that can account for this, and I explain how it avoids the implausible consequences of standard psychological continuity theory, as well as having certain other advantages over that theory.

Do you persist as the same person over time because you keep the same mind or because you keep the same body? Philosophers have long investigated this question of personal identity with thought experiments. Cognitive scientists have joined this tradition by assessing lay intuitions about those cases. Much of this work has focused on judgments of identity continuity. But identity also has practical significance: obligations are tagged to one's identity over time. Understanding how someone persists as the same person over (...) time could provide insight into how and why moral and legal obligations persist. In this paper, we investigate judgments of obligations in hypothetical cases where a person's mind and body diverge (e.g., brain transplant cases). We find a striking pattern of results: In assigning obligations in these identity test cases, people are divided among three groups: “body‐followers,” “mind‐followers,” and “splitters”—people who say that the obligation is split between the mind and the body. Across studies, responses are predicted by a variety of factors, including mind/body dualism, essentialism, education, and professional training. When we give this task to professional lawyers, accountants, and bankers, we find they are more inclined to rely on bodily continuity in tracking obligations. These findings reveal not only the heterogeneity of intuitions about identity but how these intuitions relate to the legal standing of an individual's obligations. (shrink)

In this paper, I first argue that sometimes freely and knowingly manipulating oneself does not fully preserve moral responsibility – namely, in cases of practically distinct self-manipulation. However, I argue that practically distinct self-manipulation preserves moral responsibility to some extent because such a self-manipulated person is more morally responsibility than an other-manipulated person. This is an important result: manipulating oneself doesn’t always fully preserve one’s moral responsibility for one’s actions. But in what sense is the self-manipulated person more morally responsible? (...) I argue the self-manipulated person is not a fitting target of the reactive attitudes but continues to have wrongdoing-incurred reparative obligations. This explains the intuitive judgement about the self-manipulated person, provides a better explanation of “tracing” cases, and reveals important requirements for a plausible theory of moral responsibility.

In this discussion note, I aim to reconstruct and assess Korsgaard's recent attempt to extend her regress argument. I begin, in section 1, with a brief recapitulation of the regress argument. Then, in section 2, I turn to the extension.

This study deals specifically with one of the most relevant issues in neuro-ethics, namely the philosophical classification of so-called memory dampening, which refers to the attenuation of traumatic memories with the help of medication. Numerous neuroethical questions emerge from this issue. For example, how is a person’s identity affected by using such drugs? Does one still remain the same person? Would propranolol, for example, as a memory-dampening agent lead to a fundamental change in one’s identity? Are not a person’s negative (...) memories also part of their identity and present personality? These questions are examined from the perspective of the seventeenth-century Islamic philosopher, Mullā Ṣadrā. The goal is to shed light on the neuroethical foundations of memory dampening and personal identity from an Islamic philosophical perspective. (shrink)

The role of autobiographical memory is not just to relate us to our past self, but also to shape the future self of ours by helping us navigate the complex world we encounter in our every-day lives on a stable basis: some more or less vivid idea of who we really are as persons, as individual beings with distinct selves and unique identities. In this sense memory has also to do with being and becoming, and not just with having been. (...) The advances in the field of memory neuroscience have resulted in what is called memory reconsolidation, that is, techniques to suppress, modify, or enhance certain memories that have to do with our moral identity and moral status. In this presentation I will discuss certain potential implications of memory reconsolidation that are in my view of key importance for neuroethics, and especially for the debate concerning moral identity, agency and status in the brand-new landscape that has been shaped by the novel capabilities neuroscience has made available.

The crux of this paper is to provide a concentrated critical evaluation of Galen Strawson's innovative approach to the self. To that end, I will first attempt to concisely introduce his general thesis, which seems appropriate to be broken up into two major pieces: the phenomenology (experience) of the self, what the self would have to be; and the metaphysics of the self (i.e., a query refers to its metaphysics [its existence and nature]: whether there is any). Explaining and discussing (...) Strawson's twofold account of the self is my first target in this paper. And it is with these two parts that I take issues. Accordingly, I shall determinedly try to develop a counterargument according to which Strawson's establishment of his entire enterprise of the self is based merely on unjustified intuitive generalisation. Next, I will put more effort into making some more argumentative points, mainly to show how his metaphysics does not give much thought to some vital matters of the self in comparison with the systems of metaphysics of his forebears of Western philosophers. What all this means is that Strawsonian metaphysical analysis of the self so conceived and so described appears philosophically to drive itself to justly be placed in an ahistorical context.

A prominent view on personal identity over time, Jeff McMahan’s ‘Embodied Mind Account’ (2002) holds that we cease to exist only once our brains can no longer sustain the basic capacity to uphold consciousness. One of the many implications of this view on identity persistence is that we continue to exist throughout even the most severe cases of dementia, until our consciousness irreversibly shuts down. In this paper, I argue that, while the most convincing of prominent accounts of personal identity (...) over time, McMahan’s account faces serious challenges in explanatory power of dementias and related neurodegenerative conditions. Particularly, this becomes visible in the face of emerging methods for neural tissue regeneration, and the possibility of ‘re-emerging patients’. I argue that medical professionals’ neglecting qualitative aspects of identity risks resulting in grave misunderstandings in decision-making processes, and ethically objectionable outcomes in future practices. Finally, I propose revisions which could potentially salvage the great benefits that Embodied Mind Theory still can bring to the field of dementia care in terms of understanding life, death, and identity across the lifespan.

Many philosophers have become sceptical of the use of thought experiments in theorising about personal identity. In large part this is due to work in experimental philosophy that appears to confirm long held philosophical suspicions that thought experiments elicit inconsistent judgements about personal identity, and hence judgements that are thought to be the product of cognitive biases. If so, these judgements appear to be useless at informing our theories of personal identity. Using the methods of experimental philosophy, we investigate whether (...) people exhibit inconsistent judgements and, if they do, whether these judgements are likely to be the source of cognitive bias or, instead, sensitivity to some relevant factor. We do not find that people’s judgements are sensitive to any of the factors we investigate (relevant or irrelevant), nor that people have inconsistent judgements across cases. Rather, people’s judgements are best explained by them having a very minimal account of what it takes for a person to survive. Since this pattern of judgements is no reason to think that we are subject to cognitive bias, we see no reason, as things stand, to be sceptical of our judgements. (shrink)

The view that it is possible for someone to think at a time without existing at that time is not only perfectly coherent but in harmony with an attractive externalist view of the mental. Furthermore, it offers plausible solutions to various puzzles of personal identity.

Good physical experiments conform to the basic methodological standards of experimental design: they are objective, reliable, and valid. But is this also true of thought experiments? Especially problems of personal identity have engendered hypothetical scenarios that are very distant from the actual world. These imagined situations have been conspicuously ineffective at resolving conflicting intuitions and deciding between the different accounts of personal identity. Using prominent examples from the literature, I argue that this is due to many of these thought experiments (...) not adhering to the methodological standards that guide experimental design in nearly all other disciplines. I also show how empirically unwarranted background assumptions about human physiology render some of the hypothetical scenarios that are employed in the debate about personal identity highly misleading.

Ordinary judgments about personal identity are complicated by the fact that phrases like “same person” and “different person” have multiple uses in ordinary English. This complication calls into question the significance of recent experimental work on this topic. For example, Tobia (2015) found that judgments of personal identity were significantly affected by whether the moral change described in a vignette was for the better or for the worse, while Strohminger and Nichols (2014) found that loss of moral conscience had more (...) of an effect on identity judgments than loss of biographical memory. In each case, however, there are grounds for questioning whether the judgments elicited in these experiments engaged a concept of numerical personal identity at all (cf. Berniūnas and Dranseika 2016; Dranseika 2017; Starmans and Bloom 2018). In two pre-registered studies we validate this criticism while also showing a way to address it: instead of attempting to engage the concept of numerical identity through specialized language or the terms of an imaginary philosophical debate, we should consider instead how the identity of a person is described through the connected use of proper names, definite descriptions, and the personal pronouns “I”, “you”, “he”, and “she”. When the experiments above are revisited in this way, there is no evidence that the differences in question had an effect on ordinary identity judgments. (shrink)
