Michel Gondry and Charlie Kaufman’s 2004 Eternal Sunshine of the Spotless Mind, which celebrated its fifteenth anniversary in 2019, is an extended thought experiment on the nature of memory, minds, and persons. The memory erasure thought experiment presented in the film—and its implications for personal identity—raises poignant questions for the ethicist, epistemologist, neuroscientist, metaphysician, and cognitive scientist. In this paper, I explore the rich insights the film has to offer interdisciplinary studies of memory, providing a case study in how narrative (...) can uniquely contribute to memory research, while also maintaining philosophical rigor and fidelity to scientific discoveries about memory. Turning to the philosophical implications of memory erasure, I consider memory erasure in the context of several leading views of personal identity and proposed answers to the persistence question of personal identity, assessing the challenges and complications that the memory erasure thought experiment brought to life by Eternal Sunshine poses to these theories. I argue that the psychological continuity view of personal identity—in its various iterations—does not allow an individual to truly survive the memory erasure procedure. The memory erasure thought experiment presented in Eternal Sunshine—and its metaphysical and epistemological consequences—reveal how we establish the relationship between memories and selfhood, how to define personhood in the presence of both hypothetical and real-world memory loss, and what experiences we value in human life.

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same time. This result undermines (...) some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

Philosophers disagree about whether there could be “zombies”: beings physically identical to normal human people but lacking consciousness. Establishing their possibility would refute physicalism. But it is seldom noted that the popular “constitution view” of human people implies that our bodies actually are zombies. This would contradict several widely held views in the philosophy of mind.

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

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.

In this paper, I focus on a kind of medical intervention that is at the same time fascinating and disturbing: identity-changing interventions. My guiding question is how such interventions can be ethically justified within the bounds of contemporary bioethical mainstream that places great weight on the patient9s informed consent. The answer that is standardly given today is that patients should be informed about the identity effects, thus suggesting that changes in identity can be treated like ‘normal’ side effects. In the (...) paper, I argue that this approach is seriously lacking because it misses important complexities going along with decisions involving identity changes and consequently runs into mistakes. As a remedy I propose a new approach, the ‘perspective-sensitive account’, which avoids these mistakes and thus provides the conceptual resources to systematically reflect on and give a valid consent to identity-changing interventions.

This paper outlines the often striking parallels of various approaches to ontic vagueness, as well as their even more striking differences. Though circling around the same idea, some of these approaches were developed to solve quite diverse theoretical problems and encounter different challenges. In addition to these difficulties, the frequently disregarded epistemological problems of all theories of ontic vagueness turn out to be even more serious under critical scrutiny. The same holds for the difficulties of deciding, for every case of (...) vagueness, whether the vagueness involved is semantic or ontic. (shrink)

I examine the familiar criterial view of personhood, according to which the possession of personal properties such as self-consciousness, emotionality, sentience, and so forth is necessary and sufficient for the status of a person. I argue that this view confuses criteria for personhood with parts of an ideal of personhood. In normal cases, we have already identified a creature as a person before we start looking for it to manifest the personal properties, indeed this pre-identification is part of what makes (...) it possible for us to see and interpret the creature as a person in the first place. This pre-identification is typically based on biological features. Except in some interesting special or science-fiction cases, some of which I discuss, it is human animals that we identify as persons. (shrink)

Genetic information is becoming increasingly used in modern life, extending beyond medicine to familial history, forensics and more. Following this expansion of use, the effect of genetic information on people’s identity and ultimately people’s quality of life is being explored in a host of different disciplines. While a multidisciplinary approach is commendable and necessary, there is the potential for the multidisciplinarity to produce conceptual misconnection. That is, while experts in one field may understand their use of a term like ‘gene’, (...) ‘identity’ or ‘information’ for experts in another field, the same term may link to a distinctly different concept. These conceptual misconnections not only increase inefficiency in complex organisational practices, but can also have important ethical, legal and social consequences. This paper comes at the problem of conceptual misconnection by clarifying different uses of the terms ‘gene’, ‘identity’ and ‘information’. I start by looking at three different conceptions of the gene; the Instrumental, the Nominal and the Postgenomic Molecular. Secondly, a taxonomy of four different concepts of identity is presented; Numeric, Character, Group and Essentialised, and their use is clarified. A general concept of Information is introduced, and finally three distinct kinds of information are described. I then introduce Concept Creep as an ethical problem that arises from conceptual misconnections. The primary goal of this paper is to reduce the potential for conceptual misconnection when discussing genetic identity and genetic information. This is complimented by three secondary goals—1) to clarify what a conceptual misconnection is, 2) to explain why clarity of use is particularly important to discussions of genes, identity and information and 3) to show how concept creep between different uses of genetic identity and genetic information can have important ethical outcomes.

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.

_Purpose._ The authors of this article aim to reveal how motivation and legitimacy ensure the normativity of the structuring and genesis of multiple social identity. _Theoretical basis._ Social constructivism was chosen as a research methodology. It reveals social identity as an identity constructed by its bearer on the basis of ready-made versions of social identity proposed by social groups and society. Social circles, identified by Georg Simmel, unite representatives of different social groups into a wider oneness, which can be interpreted (...) as a multiple social identity, and the motivation for its formation can be identified on the basis of Weber’s concept of legitimacy. _Originality._ Identifying the structure and genesis of a multiple social identity creates prerequisites for establishing its normative foundations, as well as for a specific analysis of the procedures for achieving its motivation and legitimacy. Georg Simmel’s concept of social virtues promotes consideration of the basic virtues of an individual as those that enable one’s to be a member of various social groups in which these virtues are manifested. _Conclusions._ The social virtues present in the social identities that are part of a multiple social identity determine not only the social status of these individuals in these social groups but also the ranking and normative significance of these groups for this individual. If the observance of virtues in a certain social group causes a higher motivation of an individual’s behavior, then this group acquires a higher legitimacy for her/him. Using the example of virtues, it is possible to search for other possible grounds for the formation of multiple social identity. Such grounds are primarily other characteristics of key social practices that support different social groups. (shrink)

Memory, as is well known, makes up a large part of our identity (even though the criterion of this “identity” is controversial). Documents – understood as inscriptions – make up our external memory in a peculiar way: they constitute both a stable anchor and a reference-point for our personal transformations over time. There is, however, also an internal memory, residing in our brain. This is based in part on external documentation; but it is of course not exclusively tied thereto. Rather (...) it evolves dynamically over time, in part reflecting ethical debates which we carry on within ourselves and which is influenced also by emotional factors, for example as we try to erase memories that are unpleasant. If, for example, the internal memory of some offense against our person is erased, then the motivation to testify against those who offended against us no longer exists or is greatly reduced, and this is so even though the documents that record the offense remain. Our motivations here depend on the emotional factor in our memories; once this has been lost, even though the autobiographical, episodic memory still remains, then the value-significance of the event fades from our view, and with it the impulse to act. Emotions are in large part responsible for creating a bond with documents; they make it possible for our internal and external memories to have significance. There must be some degree of emotional resonance in inscriptions relating to events in the past, which arises out of our own experience of these events and from our memory of these experiences, for these inscriptions to have significance in our lives. Documents are thus fundamental. But for ourselves and for our social lives, they must be supplemented by internal memories. (shrink)

Ein Leitmotiv der medizinethischen Auseinandersetzung mit der tiefen Hirnstimulation (THS) ist die Beschäftigung mit Fragen personaler Identität. Da es sich bei personaler Identität auch um ein Problem der theoretischen Philosophie handelt, wird in diesem Aufsatz nicht nur die praktische Frage nach der ethischen Legitimation der THS durch informierte Einwilligung gestellt und ein modifiziertes Legitimationskriterium für wesensändernde THS erarbeitet. Vielmehr wird zunächst versucht, das Problem, um das es in der Debatte um THS und personaler Identität geht, besser zu verstehen.
