In this chapter, we outline the interdisciplinary contributions that philosophy, psychology, and neuroscience have provided in the understanding of the self and identity, focusing on one specific line of burgeoning research: the importance of morality to perceptions of self and identity. Of course, this rather limited focus will exclude much of what psychologists and neuroscientists take to be important to the study of self and identity (that plethora of self-hyphenated terms seen in psychology and neuroscience: self-regulation, self-esteem, self-knowledge, self-concept, self-perception, (...) and more). We will likewise not engage with many canonical philosophical treatments of self and identity. But we will lay out a body of research that brings together classic themes in philosophy, psychology, and neuroscience to raise empirically tractable philosophical questions, and philosophically rigorous empirical questions about self and identity. More specifically, in section 4.2, we will review some recent research that has treated traditional philosophical questions about self and identity as empirical questions. Within this body of work, we will be primarily concerned with the finding that morality (more so than memory) is perceived to be at the core of self and identity. Then, in section 4.3, we raise and respond to a variety of questions and criticisms: first, about the operationalization of identity concepts in the empirical literature; second, about the generalizability of the moral self effect; third, about the direction of change; fourth, about connections with recent work in neuroscience; and fifth, about the target of evaluation. Finally, in section 4.4, we consider a variety of implications and applications of this work on the moral self. Throughout, we aim to highlight connections between classical themes in philosophy, psychology, and neuroscience, while also suggesting new directions for interdisciplinary collaboration. (shrink)

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on personal identity.

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person.

Much work has highlighted the degree to which children and adults view human characteristics as immutable. Less work has elucidated how people may conceptualize such immutability. Using immigration as an example domain, we examined the extent to which children’s (N=112 5- to 10-year-olds) immutability concepts reflected beliefs about others lacking the ability and/or the desire to change. Children readily agreed that immigrants could—and wanted to—change certain aspects of their identities (i.e., by adopting the norms of their new country). We also (...) investigated the social ramifications of messages focusing on different aspects of immutability. Children felt and behaved more positively toward people who had the ability and desire to change than toward those who did not. Moreover, information about desires played a greater role in shaping children’s attitudes and behaviors than did information about abilities. This work extends scholarship on psychological essentialism by highlighting the need to study sub-components of a specific pillar of essentialist thought (i.e., separating the immutability component of essentialism into perceptions regarding people's perceived desire and, separately, perceived ability to change), partially because essentialism impacts social cognition and behavior differently across sub- components.

ABSTRACTJohn Locke is famous for popularizing the method of the philosophical thought experiment in discussions of personal identity; the cases introduced in the second edition of An Essay Concerning Understanding are still employed by contemporary philosophers. Here I argue that Locke’s method is nonetheless importantly different from later efforts in ways that can help us better appreciate his larger projects. Rather than pumping the reader’s intuitions in support of his preferred account, Locke’s thought experiments serve to illustrate common errors in (...) assessments of identity that he sees as particularly prevalent and problematic. Locke defends his idea of ‘person’ otherwise, through what I call his ‘lived experiments’: observations about linguistic usage that serve to illustrate the term’s role in practical reasoning. I focus especially on Locke’s example of the forensic status of the madman. Examples like these do not, for Locke, demonstrate the intuitiveness of his analysis, but rather bolste... (shrink)

Most contemporary accounts of moral responsibility take desert to play a central role in the nature of moral responsibility. It is also assumed that desert is a backward-looking concept that is not directly derivable from any forward-looking or consequentialist considerations, such as whether blaming an agent would deter the agent from performing similar bad actions in the future. When determining which account of moral responsibility is correct, proponents of desert-based accounts often take intuitions about cases to provide evidence either in (...) favor of or against a proposed theory. In this paper, I discuss two experiments that test whether folk intuitions accord with what desert-based accounts would predict. Results suggest that moral responsibility intuitions are sensitive to forward-looking considerations, thus posing a problem for desert-based accounts of moral responsibility. If appealing to intuitions about cases is a valid method of discovering the nature of moral responsibility and desert, it seems either desert is not entirely backward-looking or moral responsibility is not exclusively desert-based. These experimental results also suggest that consequentialist accounts of moral responsibility, which have largely been abandoned due to their counterintuitive nature, are perhaps not so counterintuitive after all.

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)

A dissociated area of medical research warrants bioethical consideration: a proposed transplantation of a donor’s entire body, except head, to a patient with a fatal degenerative disease. The seeming improbability of such an operation can only underscore the need for thorough bioethical assessment: Not assessing a case of such potential ethical import, by showing neglect instead of facing the issue, can only compound the ethical predicament, perhaps eroding public trust in ethical medicine. This article discusses the historical background of full-body (...) transplantation, documents the seriousness of its current pursuit, and builds an argument for why prima facie this type of transplant is bioethically distinct. Certainly, this examination can only be preliminary, indicating what should be a wide and vigorous discussion among practitioners and ethicists. It concludes with practical suggestions for how the medical and bioethics community may proceed with ethical assessment. (shrink)

In a recent paper, I argued that philosophical intuitions are surprisingly robust both across demographic groups and across development. Machery and Stich reply by reviewing a series of studies that do show significant differences in philosophical intuition between different demographic groups. This is a helpful point, which gets at precisely the issues that are most relevant here. However, even when one looks at those very studies, one finds truly surprising robustness. In other words, despite the presence of statistically significant differences (...) between demographic groups, a core finding coming out of those studies is that philosophical intuitions are surprisingly robust across demographic groups.

Our study explores the folk concept of personal identity in the developmental context. Two hundred and seventeen Czech children participated in an interview study based on a hypothetical scenario about a sudden change in their friend, someone they know, or some other unspecified person. The children were asked to judge to what extent particular changes (from six categories of traits) would change the identity core of their friend or some other person on a seven-point scale. We introduced both positive and (...) negative versions of the changes. Our data suggest that children considered moral traits connected to interpersonal relationships crucial for preserving personal identity. Memory connected to personal experiences also scored highly. On the other hand, a change in physical appearance seemed to have the least important impact on personal identity. Negative changes turned out to have a significantly greater impact than positive changes in all categories, except the physical. Possible effects of scenario and the participants’ age and sex were further explored. We discuss the possible causes of the effect of negative moral change and the role of social dimension in the development of the concept of personal identity. (shrink)

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)

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person after (...) becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.

The question of transtemporal identity of objects in general and persons in particular is an important issue in both philosophy and psychology. While the focus of philosophers traditionally was on questions of the nature of identity relation and criteria that allow to settle ontological issues about identity, psychologists are mostly concerned with how people think about identity, and how they track identity of objects and people through time. In this article, we critically engage with widespread use of inferring folk judgments (...) of identity from study participants’ use of proper names in response to experimental vignettes. We provide reasons to doubt that using this method one can reliably infer judgments of numerical identity over time and transformations. We also critically examine allegedly-Kripkean justification of this method and find it lacking. Merely assuming that names are rigid designators will not help. A study participant’s use of proper names can be taken to track the participant’s identity judgments only if supported by the participant’s belief that names used in the scenario are used rigidly.

People sometimes explain behavior by appealing to an essentialist concept of the self, often referred to as the true self. Existing studies suggest that people tend to believe that the true self is morally virtuous; that is deep inside, every person is motivated to behave in morally good ways. Is this belief particular to individuals with optimistic beliefs or people from Western cultures, or does it reflect a widely held cognitive bias in how people understand the self? To address this (...) question, we tested the good true self theory against two potential boundary conditions that are known to elicit different beliefs about the self as a whole. Study 1 tested whether individual differences in misanthropy—the tendency to view humans negatively—predict beliefs about the good true self in an American sample. The results indicate a consistent belief in a good true self, even among individuals who have an explicitly pessimistic view of others. Study 2 compared true self-attributions across cultural groups, by comparing samples from an independent country and a diverse set of interdependent countries. Results indicated that the direction and magnitude of the effect are comparable across all groups we tested. The belief in a good true self appears robust across groups varying in cultural orientation or misanthropy, suggesting a consistent psychological tendency to view the true self as morally good.

Why is it that forgetting moral knowledge, unlike other paradigmatic examples of knowledge, seems so deeply absurd? Previous authors have given accounts whereby moral forgetting in itself either is uniformly absurd and impossible (Gilbert Ryle, Adam Bugeja) or is possible and only the speech act is absurd (Sarah McGrath). Considering findings in moral psychology and the experimental philosophy of personal identity, I argue that the knowledge of some moral truths—especially those that are emotional, widely held, subjectively important, and contribute to (...) social relationships—cannot be forgotten because they’re too tightly tied to one’s true self. Moral knowledge at the level of individual propositions, when it does not have these attributes and so is not so tied to the agent’s identity, can sometimes be forgotten. I identify two such cases: (1) where the moral knowledge results partly from an emotional trigger that has been forgotten, and (2) where the moral knowledge results partly from a process of reflection that has been forgotten.

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)

What justifies our holding a person morally responsible for some past action? Why am I justified in having a special prudential concern for some future persons and not others? Why do many of us think that maximizing the good within a single life is perfectly acceptable, but maximizing the good across lives is wrong? In these and other normative questions, it looks like any answer we come up with will have to make an essential reference to personal identity. So, for (...) instance, it seems we are justified in holding X responsible for some past action only if X is identical to the person who performed that action. Further, it seems I am justified in my special concern for some future person only if he will be me. Finally, many of us think that while maximization within a life affects only one person, a metaphysical unity, maximization across lives affects many different, metaphysically distinct, persons, and so the latter is wrong insofar as it ignores this fundamental separateness of persons.

A long tradition of psychological research has explored the distinction between characteristics that are part of the self and those that lie outside of it. Recently, a surge of research has begun examining a further distinction. Even among characteristics that are internal to the self, people pick out a subset as belonging to the true self. These factors are judged as making people who they really are, deep down. In this paper, we introduce the concept of the true self and (...) identify features that distinguish people’s understanding of the true self from their understanding of the self more generally. In particular, we consider recent findings that the true self is perceived as positive and moral, and that this tendency is actor-observer invariant and cross-culturally stable. We then explore possible explanations for these findings and discuss their implications for a variety of issues in psychology. (shrink)
