Two of the main contenders in the debate about personal persistence over time are the neo-Lockean psychological continuity view and animalism as defended by Olson and Snowdon. Both are wrong. The position I shall argue for, which I call, following Olson, the hybrid view, takes psychological continuity as a sufficient but, pace the neo-Lockeans, not necessary condition for personal persistence. It sides with the animalist in allowing that mere biological continuity is also sufficient. So I am, in a sense, a (...) psychological continuity theorist. But I am also in a sense, a biological theorist. (shrink)

To the extent that the performance of embodied and situated cognitive agents is predicated on fore- thought;such agents must remember; and learn from; the past to predict the future. In complex; non-stationaryenvironments; such learning is facilitated by an intrinsic motivation to seek novelty. A significant part of anagent’s identity is thus constituted by its remembered distilled cumulative life experience; which the agent isdriven to constantly expand. The combination of the drive to novelty with practical limits on memorycapacity posits a problem. (...) On the one hand; because novelty seekers are unhappy when bored; merelyreliving past positive experiences soon loses its appeal: happiness can only be attained sporadically; via anopen-ended pursuit of new experience. On the other hand; because the experiencer’s memory is finite;longevity and continued novelty; taken together; imply eventual loss of at least some of the stored content;and with it a disruption of the constructed identity. In this essay; I examine the biobehavioral and cognitive-computational circumstances that give rise to this problem and explore its implications for the humancondition. (shrink)

Derek Parfit’s early work on the metaphysics of persons has had a vast influence on Western philosophical debates about the nature of personal identity and moral theory. Within the study of Buddhism, it also has sparked a continuous comparative discourse, which seeks to explicate Buddhist philosophical principles in light of Parfit’s conceptual framework. Examining important Parfitian-inspired studies of Buddhist philosophy, this article points out various ways in which a Parfitian lens shaped, often implicitly, contemporary understandings of the anātman doctrine and (...) its relation to Buddhist ethics. I discuss in particular three dominant elements appropriated by Parfitian-inspired scholarship: Parfit’s theoretical categories; philosophical problems raised by his reductionist theory of persons; and Parfit’s argumentative style. I argue that the three elements used in this scholarship constitute different facets of one methodological approach to cross-cultural philosophy, which relies on Western terminology and conceptual schemes to establish a conversation with non-Western philosophy. I suggest that while this methodology is fruitful in many ways, philosophy as a cosmopolitan space may benefit significantly from approaching Buddhist philosophy using its own categories and terminology.

Traditionally, this puzzle has been solved in various ways. Aristotle, for example, distinguished between “accidental” and “essential” changes. Accidental changes are ones that don't result in a change in an objects' identity after the change, such as when a house is painted, or one's hair turns gray, etc. Aristotle thought of these as changes in the accidental properties of a thing. Essential changes, by contrast, are those which don't preserve the identity of the object when it changes, such as when (...) a house burns to the ground and becomes ashes, or when someone dies. Armed with these distinctions, Aristotle would then say that, in the case of accidental changes, (1) and (2) are both false—a changing thing can really change one of its “accidental properties” and yet literally remain one and the same thing before and after the change.

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)

This PhD thesis focuses on the philosophical foundations of Neuroeconomics, an innovative research program which combines findings and modelling tools from economics, psychology and neuroscience to account for human choice behaviour. The proponents of Neuroeconomics often manifest the ambition to foster radical modifications in the accounts of choice behaviour developed by its parent disciplines. This enquiry provides a philosophically informed appraisal of the potential for success and the relevance of neuroeconomic research for economics. My central claim is that neuroeconomists can (...) help other economists to build more predictive and explanatory models, yet are unlikely to foster revolutionary modifications in the economic theory of choice. The contents are organized as follows. In chapters 1-2, I present neuroeconomists’ investigative tools, distinguish the most influential approaches to neuroeconomic research and reconstruct the case in favour of a neural enrichment of economic theory. In chapters 3-7, I combine insights from neuro-psychology, economic methodology and philosophy of science to develop a systematic critique of Neuroeconomics. In particular, I articulate four lines of argument to demonstrate that economists are provisionally justified in retaining a methodologically distinctive approach to the modelling of decision making. My first argument points to several evidential and epistemological concerns which complicate the interpretation of neural data and cast doubt on the inferences neuroeconomists often make in their studies. My second argument aims to show that the trade-offs between the modelling desiderata that neuroeconomists and other economists respectively value severely constrain the incorporation of neural insights into economic models. My third argument questions neuroeconomists’ attempts to develop a unified theory of choice behaviour by identifying some central issues on which they hold contrasting positions. My fourth argument differentiates various senses of the term ‘revolution’ and illustrates that neuroeconomists are unlikely to provide revolutionary contributions to economic theory in any of these senses.

The cohabitation theory is a popular solution to the problem of personal fission. It affirms that all the people who result from fission were there cohabiting the pre-fission body all along. Adopting this solution is an uncontroversial move for four-dimensionalists, but is it open to three-dimensionalists too? Some have thought so, but Katherine Hawley, Mark Johnston, and Eric Olson have argued to the contrary. They claim three-dimensionalists simply cannot be cohabitation theorists. In this paper, I explain how they can.

As common experience confirms, procrastination seems not only possible, but widespread. However, procrastination should not be taken for granted. Often, the procrastinator harms herself knowingly. It thus clearly seems that such a person lacks the self-concern that usually characterises us. After having spelled out what procrastination is, and having explored its main varieties, I consider the relation between procrastination and risk-taking. After this, I discuss the implications of this phenomenon for the debates about personal identity. The upshot, I argue, is (...) that reductionist accounts, according to which identity is a matter of psychological continuity, are in a better position as might have been thought. (shrink)

It is often argued that associations are intelligent organisms with minds and intentional states of their own. It is also argued that groups are merely a plurality of individuals who are related or associated only in a specific and limited sense. This paper draws on both classical and contemporary scholarship to develop an ontological account of persons which has real-world legal and ethical implications.

Philosophers have long suggested that our attitude of special concern for the future is problematic for a reductionist view of personal identity, such as the one developed by Derek Parfit in Reasons and Persons. Specifically, it is often claimed that reductionism cannot provide justification for this attitude. In this paper, I argue that much of the debate in this arena involves a misconception of the connection between metaphysical theories of personal identity and our special concern. A proper understanding of this (...) connection reveals that the above-mentioned objection to reductionism cannot get off the ground. Though the connection I propose is weaker than the connection typically presupposed, I nonetheless run up against a conclusion reached by Susan Wolf in “Self-Interest and Interest in Selves.” According to Wolf, metaphysical theses about the nature of personal identity have no significance for our attitude of special concern. By arguing against Wolf’s treatment of self-interest, I suggest that her arguments for this conclusion are misguided. This discussion leads to further clarification of the nature of the link between theories of personal identity and our special concern and, ultimately, to a better understanding of the rationality of this attitude.

Richard Swinburne is one of the most important figures in philosophy of religion who took special interest in the soul. Also he is one of the most prominent defenders of dualism –also known as mind-body dualism or substance dualism– that regards humans as composed of two different substances called body and the soul. He defended the dualist view against contemporary problems of dualism and contributed to it with his three books, namely The Evolution of the Soul; Mind, Brain and Free (...) Will and Are We Bodies or Souls? alongside with other publications. In this paper, I will introduce Swinburne’s version of Cartesian dualism and critically investigate whether it provides us some reasons to believe in the soul. For this reason, I will examine the two principle arguments Swinburne offers in the explanations of dualism –one of them is known as the conceivability argument and the other is based on an imaginary scenario from transplants– along with their critics. To sum up, the main point drawn in this paper will be Swinburne’s arguments for dualism along with some of their critics. (shrink)

Two conditions guiding permissible use of force in self-defence are proportionality and success. According to the proportionality condition the means used to prevent an attack can be permissible only if they are proportional to the interest at stake.1 According to the success condition, otherwise impermissible acts can be justified under the right to self-defence only if they are likely to succeed in preventing the perceived threat.2 These requirements should not always be interpreted narrowly.

Eric Olson has argued, startlingly, that no coherent account can be giv- en of the distinction made in the personal identity literature between ‘complex views’ and ‘simple views’. ‘We tell our students,’ he writes, ‘that accounts of personal identity over time fall into [these] two broad categories’. But ‘it is impossible to characterize this distinction in any satisfactory way. The debate has been systematically misdescribed’. I argue, first, that, for all Olson has said, a recent account by Noonan provides the (...) coherent characterization he claims impossible. If so we have not been wrong all along in the way he says in what we have been telling our students. I then give an account of the distinction between the reductionist and non-reductionist positions which makes it differ- ent from the complex/simple distinction. The aim is to make clear sense of the notion of a not simple but non-reductionist position — which seems an eminently reasonable possibility and something it may also be useful to tell our students about.

In African philosophical literature, and especially in Afro-communitarianism, there are discussions about the value of the relationship an individual has with her respective community. By community, reference is made to the metaphysical holistic view of community which includes all beings in nature. But since the article deals with gender, which is a social construction, most of the arguments appeal to a narrower version of community, that of human beings. Therefore, discussions about “value” refer to the value that is given to (...) the relationship that surpasses any individual value, and it applies or appeals to human beings. One implication of this understanding and the prioritisation of the relationship is that identity is something that is conferred by this sort of relationship. In this article, we argue that this way of understanding “identity” from an Afro-communitarian world view has something to offer in understanding or conceptualising gender(ed) identity(ies). The assumption is that gender identity will be understood as socially conferred and most importantly, one that takes community as essential. (shrink)

If a brain is uploaded into a computer, will consciousness continue in digital form or will it end forever when the brain is destroyed? Philosophers have long debated such dilemmas and classify them as questions about personal identity. There are currently three main theories of personal identity: biological, psychological, and closest continuer theories. None of these theories can successfully address the questions posed by the possibility of uploading. I will argue that uploading requires us to adopt a new theory of (...) identity, psychological branching identity. Psychological branching identity states that consciousness will continue as long as there is continuity in psychological structure. What differentiates this from psychological identity is that it allows identity to continue in multiple selves. According to branching identity, continuity of consciousness will continue in both the original brain and the upload after nondestructive uploading. Branching identity can also resolve long standing questions about split-brain syndrome and can provide clear predictions about identity in even the most difficult cases imagined by philosophers.

Ordinary normative discourse includes talk about the reasons for action we had in the past but only came to discover in hindsight. In some cases, we come to discover these reasons not because new information has come to light, but because our values have changed. Contemporary metaethical views, namely Street's Humean constructivism and Blackburn's and Gibbard's quasi-realism, have some difficulty accounting for these reasons and the claims we make about them. This difficulty hinges on the diachronic complexity of these reasons (...) and claims. It cannot be the case that these reasons were constructed by the perspective we had in the past before our values changed. If there were no extant reasons in the past, then it would seem that our claims about them in the present cannot be true. Quasi-realists can account for the way in which reason claims purport to be true by appealing to a deflationary sense of truth and so can remain agnostic on the actual existence of these reasons. Nevertheless, Street argues that t.. (shrink)

This paper examines three proposals on the difference between the complex and the simple view about personal identity: Parfit’s original introduction of the distinction, Gasser and Stefan’s definition, and Noonan’s recent proposal. I argue that the first two classify the paradigm cases of simplicity as complex, while Noonan’s proposal makes simplicity and complexity turn on features whose relevance for the distinction is questionable. Given these difficulties, I examine why we should be interested in whether a position is complex or simple. (...) I describe two purposes of having a distinction, and show that extant accounts of the complex versus simple distinction fail to serve these. I argue that unless we find a satisfying account of the difference between complex and simple positions, we should not frame discourses on personal identity in these terms. (shrink)

Is amnesia the mother of discontinuity? Perhaps surprisingly, amnesia is perfectly compatible with psychological continuity. Think, for example, of David Wiggins’ version of Locke.

This paper seeks to lay down the theoretical groundwork for the emergence of holistic cross-cultural philosophical investigations of personal identity ¾ investigations that approach the theoretical, phenomenological, psychological, and practical-ethical dimensions of selfhood as indissociable. My strategy is to discuss three closely connected conceptual distinctions that the Buddhist approach to personal identity urges us to draw, and a lucid understanding of which is essential for the emergence of appropriately comprehensive and thus genuinely cosmopolitan discussions at the cross-road between Western and (...) Buddhist philosophical traditions. The first, primary distinction is that between the “visceral sense of self” and the “substance view of self”. This in turn gives rise to two derivative distinctions, namely between “harbouring VSS” and “believing SVS”, and between “overcoming VSS” and “rejecting SVS”. After discussing these distinctions, I consider and respond to three philosophical objections to features of Buddhist approach to selfhood that are thrown into sharper relief when attention is paid to these three distinctions. I then discuss some of the ways the foregoing may inform research in cross-cultural philosophy of personal identity. This discussion focuses on: the primacy of the first-person stance in matters of personal identity; the relationship between numerical identity and narrative identity; interdisciplinarity in the study of selfhood; and personal identity and egoism.
