Philosophers tend to be pretty impressed by human self-knowledge. Descartes (1641/1984) thought our knowledge of our own stream of experience was the secure and indubitable foundation upon which to build our knowledge of the rest of the world. Hume – who was capable of being skeptical about almost anything – said that the only existences we can be certain of are our own sensory and imagistic experiences (1739/1978, p. 212). Perhaps the most prominent writer on self-knowledge in contemporary philosophy is (...) Sydney Shoemaker. The central aim of much of his work has been to show that certain sorts of error are impossible (1963, 1988, 1994). David Chalmers has likewise attempted to show that, for a suitably constrained class of beliefs about one’s own consciousness, error is impossible (2003, sec. 4.1). Even philosophers most of the community thinks of as pessimistic about self-knowledge of consciousness seem to me, really, to be fairly optimistic. Paul Churchland, famous for his disdain of ordinary people’s knowledge about the mind, compares the accuracy of introspection to the accuracy of sense perception – pretty good, presumably, about medium-sized, nearby matters (1985, 1988). Dan Dennett, often cited as a pessimist about introspective report, actually says that we can come close to infallibility when charitably interpreted (2002). The above references concern knowledge of the stream of conscious experience, but philosophers have also tended to be impressed with our self-knowledge of our attitudes, such as our beliefs and desires. Consider this: Although I can be wrong about its being sunny outside, I can’t in the same way be wrong, it seems, about the fact that I think it’s sunny outside. Some.. (shrink)

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.

Can identity itself be vague? Can there be vague objects? Does a positive answer to either question entail a positive answer to the other? In this paper we answer these questions as follows: No, No, and Yes. First, we discuss Evans’s famous 1978 argument and argue that the main lesson that it imparts is that identity itself cannot be vague. We defend the argument from objections and endorse this conclusion. We acknowledge, however, that the argument does not by itself establish (...) either that there cannot be vague objects or that there cannot be identity statements that are indeterminate for ontic reasons. And we further acknowledge that it does not by itself establish that there cannot be identity statements that are indeterminate in virtue of the existence of vague objects. We then go on to argue that, despite this, one who believes in vague objects cannot endorse Evans’s argument. To establish this we offer supplementary arguments that show that if vague objects exist then identity is vague, and that if identity is vague then vague objects exist. Finally we draw attention to an argument parallel to that of Evans’s, but safer, which can be employed against the putative ontic indeterminacy in identity of vague objects which can be differentiated by identity-free properties.

There is much to be said for a diachronic or interpersonal individuation of singular modes of presentation (MOPs) in terms of a criterion of epistemic transparency between thought tokens. This way of individuating MOPs has been discussed recently within the mental files framework, though the issues discussed here arise for all theories that individuate MOPs in terms of relations among tokens. All such theories face objections concerning apparent failures of the transitivity of the ‘same MOP’ relation. For mental files, these (...) transitivity failures most obviously occur because mental files can merge or undergo fission. In this paper I argue that this problem is easily resolved once mental files are properly construed as continuants, whose metaphysics is analogous to that of persons or physical objects. All continuants can undergo fission or fusion, leading to similar transitivity problems, but there are well-established theories of persistence that accommodate this. I suggest that, in particular, the stage theory best suits the purposes of a continuant theory of MOPs. (shrink)

Algorithms are used across a wide range of societal sectors such as banking, administration, and healthcare to make predictions that impact on our lives. While the predictions can be incredibly accurate about our present and future behavior, there is an important question about how these algorithms in fact represent human identity. In this paper, we explore this question and argue that machine learning algorithms represent human identity in terms of what we shall call the statistical individual. This statisticalized representation of (...) individuals, we shall argue, differs significantly from our ordinary conception of human identity, which is tightly intertwined with considerations about biological, psychological, and narrative continuity—as witnessed by our most well-established philosophical views on personal identity. Indeed, algorithmic representations of individuals give no special attention to biological, psychological, and narrative continuity and instead rely on predictive properties that significantly exceed and diverge from those that we would ordinarily take to be relevant for questions about how we are.

In this quite modestly ambitious essay, I'll generally just assume that, for the most part, our "scientifically informed" commonsense view of the world is true. Just as it is with such unthinking things as planets, plates and, I suppose, plants, too, so it also is with all earthly thinking beings, from people to pigs and pigeons; each occupies a region of space, however large or small, in which all are spatially related to each other. Or, at least, so it is (...) with the bodies of these beings. And, even as each of these ordinary entities extends through some space, so, also, each endures through some time. In line with that, each ordinary entity is at least very largely, and is perhaps entirely, an enduring physical entity (which allows that many might have certain properties that aren't purely physical properties.) Further, each ordinary enduring entity is a physically complex entity: Not only is each composed of parts, but many of these parts, whether or not absolutely all of them, are themselves enduring physical entities, and many of them also are such physically complex continuing entities. When an ordinary entity undergoes a significant change, then, at least generally, this change will involve changes concerning that entity's constituting physical parts, whether it be a rearrangement of (some of) these parts, or a loss of parts, or a gain of parts, or whatever. Often, the entity will still exist even after the change occurs. As we may well suppose, this happens when, from two strokes of an ax, an ordinary log loses just a chip of wood. As we may then say, such a change conforms with the log's "persistence conditions." Somewhat less often, such an ordinary entity undergoes a change that means an end to it: When a bomb's explosion makes our log become just so many widely scattered motes of dust, the log will no longer exist. Such a momentous change doesn't conform with the log's persistence conditions. (shrink)

Locke defined a person as ‘a thinking intelligent being, that has reason and reflection, and can consider itself as itself, the same thinking thing, in different times and places”. To many who have been excited by the same thought as Locke, continuity of consciousness has seemed to be an integral part of what we mean by a person. The intuitive appeal of the idea that to secure the continuing identity of a person one experience must flow into the next experience (...) in some ‘stream of consciousoness” is evidenced by the number of attempts in the so-called constructionalist tradition to explain continuity of consciousness in terms of memory, and then build or reconstruct the idea of a person with these materials. The philosophical difficulty of the idea is plain from the failure of these attempts. Hindsight suggests this was as inevitable as the failure of the attempt to make bricks from straw alone—and as a failure just as uninteresting. Which is not to deny that the memory theorist might get from it a sense that some of the difficulties in his programme have arisen from his leaving flesh and bones, the stuff of persons, out of his construction.

Thought experiments that concoct bizarre possible world modalities are standard fare in debates on personal identity. Appealing to intuitions raised by such evocations is often taken to settle differences between conflicting theoretical views that, albeit, have practical implications for ethical controversies of personal identity in health care. Employing thought experiments that way is inadequate, I argue, since personhood is intrinsically linked to constraining facts about the actual world. I defend a moderate modal skepticism according to which intuiting across conceptually incongruent (...) worlds constitutes ‘invalid intuitioninferences’—i.e., carrying over intuitions gathered from facts about possible worlds that are at odds with facts about the actual world, for the purpose of making claims about real-life persons and their identity, leads to conceptual incongruences. Such a methodological fallout precludes accurate, informative judgments about personal identity in the actual world, calling into question the adequacy of thought experimental considerations for potential real world applications in medical ethics.

The article argues that there is a specific role for narrative consciousness in our understanding of justified responsibility ascription. Starting from a short review of empirical findings that suggest that we do not consciously control our actions, the article proceeds to spell out a concept of willed actions that does justice to the scientific results, conceptual requirements, and our most important intuitions on the ascription of responsibility. In order to do this, the article develops a concept of how narrative monitoring (...) can be said to control actions that are performed on very small time scales. This concept understands narrative monitoring as the self interpretation and disambiguation of complex cognitive systems. Finally, consequences of this concept for the ascription of responsibility are explored. (shrink)

If personhood is the quality or condition of being an individual person, brainhood could name the quality or condition of being a brain. This ontological quality would define the `cerebral subject' that has, at least in industrialized and highly medicalized societies, gained numerous social inscriptions since the mid-20th century. This article explores the historical development of brainhood. It suggests that the brain is necessarily the location of the `modern self', and that, consequently, the cerebral subject is the anthropological figure inherent (...) to modernity (at least insofar as modernity gives supreme value to the individual as autonomous agent of choice and initiative). It further argues that the ideology of brainhood impelled neuroscientific investigation much more than it resulted from it, and sketches how an expanding constellation of neurocultural discourses and practices embodies and sustains that ideology.

In the first part of the paper an argument is developed to the effect that (1) there is no moral ground for individual persons to feel responsible for or guilty about crimes of their group to which they have in no way contributed; and (2) since there is no irreducibly collective responsibility nor guilt at any time, there is no question of them persisting over time. In the second part it is argued that there is nevertheless sufficient reason for innocent (...) individual members of a group (that persists over time) to take on responsibility and guilt for the evil other (earlier) members have committed. The reason depends on the acceptability of a particular psychological theory of personal identity. (shrink)

Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the notion of fallible knowledge, (...) I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.

Philosophers commonly distinguish emotions from other feelings. For example, Anthony Kenny distinguishes emotions from both sensations and perceptions. Perceptions are connected with a specific organ or part of the body and sensations such as hunger or thirst are sometimes characteristically located in parts of the body. Emotions, however, are neither connected with organs nor characteristically felt in specific parts of the body. Kenny rightly points out that emotions and sensations are alike in one important respect, namely they are both linked (...) to characteristic forms of expression. He then says “ … the existence of characteristic expre5sions of emotion itself provides a further link between emotion and sensations: for the expression characteristic of each emotion—e.g., weeping—is itself felt, and this feeling is a genuine sensation”.

Philosophy is a radical inquiry whose task is to interrogate the fundamental assumptions of some given activity, discipline, or set of beliefs. In doing so, philosophical inquiry must attempt to delineate a problem and to develop a method for resolving that problem. However, to be true to its intention, philosophy must be able to examine not only the object of its inquiry but also its own method of interrogation. To accomplish this task, philosophical inquiry must be able to create a (...) distance not only from the assumptions under investigation but also from its own assumptions, which is to say, that it must be able to raise questions about its own method. This self-reflexivity requires that any given philosophical investigation must be examined from an alternative vantage point. Since the assumptions which inform the inquiry are deeply imbedded within a given culture, immanent critique is insufficient. The only way to step outside the boundaries of these cultural presuppositions is to reflect on the given problem from the vantage point of another culture's philosophical tradition. Thus, I argue that philosophical inquiry is unable to go beyond certain limits without being cross-cultural philosophy. I illustrate the way in which cross-cultural philosophy does this with respect to the problem of the self by placing the Western philosophical approach to this problem in dialogue with the Indian Hindu-Buddhist narrative.

Suicide as a form of political protest is a little studied social phenomenon that cannot be dismissed simply as being irrational or patholognomic. We consider protest suicide to be a meaningful social action as purposive political act intended to change oppressive policies or practices. This paper synthesizes theoretical propositions associated with suicide in general, and protest suicide in particular, so as to construct a general explanatory model of protest suicide as a social phenomenon. Then, it analyzes protest suicide as a (...) meaningful social action. People considering protest suicide have to discern the logic of the situation in which such action is to take place. This involves answering two fundamental questions: Is suicide an acceptable course of social action? Is the envisaged protest suicide likely to achieve their hopes, aspirations and goals? How these questions are answered gives rise to a set of protest suicide archetypes. Our analysis generates a more sophisticated understanding of the potential reasons for, and motivations behind, protest suicide as a social phenomenon. (shrink)

In this article, I develop and defend a conception of psychological continuity that differs from the 'orthodox' conception in terms of overlapping chains of strongly connected mental states. By recognizing the importance of the (narrative) interrelatedness of qualitatively dissimilar mental contents, as well as the role of the body in psychological continuity, I argue, serious problems confronting the orthodox view can be solved.

Animalism, the view that human persons are human animals in the most straightforward, non-derivative sense, is typically taken to conflict with the intuition that a human person would follow her functioning cerebrum were it to be transplanted into another living human body. Some animalists, however, have recently called into question the incompatibility between animalism and this “Transplant Intuition,” arguing that a human animal would be relocated with her transplanted cerebrum. In this paper, we consider the prospects for this cerebrum transplant-compatible (...) variant of animalism, which we call “Transplanimalism.” After presenting its account of three related thought experiments, and outlining its key advantages over Standard Animalism, we raise two concerns for Transplanimalism. First, we argue that Transplanimalism, like other closest-continuer accounts of the human person, encounters difficulties with symmetrical fission cases. Second, we introduce a new thought experiment that pushes Transplanimalism into surprisingly counterintuitive results. As a result of these concerns, we conclude that, despite its attractiveness, animalists should not endorse Transplanimalism. (shrink)

Issues pertaining to sex and gender continue to be some of the most hotly debated topics of our time. While many of the most heated disputes occur at the level of politics and public policy, metaphysics, too, has a crucial role to play in these debates. In this essay, I explore several key metaphysical debates concerning sex and gender through the lenses of two important areas in contemporary metaphysics: the metaphysics of essence and the ontology of the human person. The (...) goal here is not to advocate any particular position on these issues, but to show how the tools of contemporary metaphysics can help to offer a more comprehensive map of the conceptual terrain, indicating where major areas of agreement can be found and where the most important disagreements really lie.

This article intends to show that the defense of “understanding” as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one (...) hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

The so-called expertise defence against sceptical challenges from experimental philosophy has recently come under attack: there are several studies claiming to have found direct evidence that philosophers’ judgments in thought experiments are susceptible to erroneous effects. In this paper, we distinguish between the customary ‘immune experts’ version of the expertise defence and an ‘informed experts’ version. On the informed expertise defence, we argue, philosophers’ judgments in thought experiments could be preferable to those by the folk even if it were true (...) that philosophers’ judgments are no less immune to confounders than judgments by the folk are. We present results from an experimental study comparing philosophers and non-philosophers (n = 484), which support this version of the expertise defence. (shrink)

What makes an object the same persisting individual over time? Philosophers and psychologists have both grappled with this question, but from different perspectives—philosophers conceptually analyzing the criteria for object persistence, and psychologists exploring the mental mechanisms that lead us to experience the world in terms of persisting objects. It is striking that the same themes populate explorations of persistence in these two very different fields—e.g. the roles of spatiotemporal continuity, persistence through property change, and cohesion violations. Such similarities may reflect (...) an underlying connection, in that psychological mechanisms of object persistence (especially relevant parts of mid-level visual object processing) may serve to underlie the intuitions about persistence that fuel metaphysical theories. This would be a way for cognitive science to join these two disparate fields, helping to explain the possible origins and reliability of some metaphysical intuitions, and perhaps leading to philosophical progress.

The vast majority of philosophers of personal identity since John Locke have been convinced that the persistence of persons is not grounded in bodily continuity. Why? As numerous ‘textbooks’ on personal identity attest, their conviction rests, to a large extent, on an objection to the bodily approach, which concerns episodic memory. The objection invites us to a thought experiment in which we meet a person who experientially remembers events from the past of a person with a different body. The nature (...) of such first-personal memory-links is viewed as strongly suggesting that the rememberer is identical with the remembered, and hence, given the possibility of such a case, as suggesting that a person can transgress its bodily limits. The memory objection is as influential as it gets in the metaphysics of personal identity. Textbooks often portray it as the starting point of the contemporary debate about personal identity. And it has been widely perceived as a success. As everyone who has taught an introductory course on personal identity knows, the recognition of episodic-memory links in body-switching cases has the power to turn any group of novice students against bodily criteria of personal identity. In this essay, I shall specify and undermine the memory objection. I shall attempt to establish two theses. The first thesis is that the memory objection is only viable if construed as resting on the view that episodic memory contains a sense of personal identity, which teaches us about the reality of personal identity. The second thesis is that there is no such sense of personal identity, that episodic memory teaches us nothing at all about personal identity. (shrink)

It is commonly believed that our episodic memory teaches us about the reality of personal identity over time. Derek Parfitt’s notion of quasi-memory challenges this belief. According to Parfit, q-memories provide us with knowledge of past experiences in the same way that memory does, without presupposing that the rememberer and the experiencer are the same person. Various aspects of Parfit’s theory have met with criticism from scholars such as D. Wiggins, J. McDowell, M. Schechtman, and others. In this paper, I (...) will focus primarily on the holistic argument that q-memories cannot be squared with the complex nature of mental life. This is a well-known argument and, when understood as criticism of memory-trace copying, is accepted by some q-memory proponents. In this paper, I will try to show why it is impossible to defend quasi-memory, even when wholesale psychological continuity applies, and why post-fission persons are not genuine cases of q-memories.

Several contemporary philosophical theories of introspection have been offered, yet each faces a number of difficulties in providing an explanation of the exact nature of introspection. I contrast the inner-sense view that argues for a causal awareness with the acquaintance view that argues for a non-causal or direct awareness. After critically examining the inner-sense and the acquaintance views, I claim that these two views are complementary and not mutually exclusive, and that both perspectives, conceived of as modes of introspective access, (...) actually broaden the notion of introspection. I then propose a useful distinction between stimuli-induced introspection—i.e., a receptive process whereby some specific mental states induce introspection—and self-triggered introspection—i.e., a selective process whereby the individual’s own interest and volition initiates introspection. I argue that that distinction may eliminate the false dichotomy which claims that only one of those types of awareness, either the causal one or the direct one, is conducive to introspection or is defined as introspection.

Habermas's transcendentalism in Knowledge and Human Interests ( KHI) deserves to be reappraised for a number of reasons. Prevailing conceptions of strong transcendental arguments, which inform many of his critics, cannot be sustained. The analytic reception of Kant suggests a more modest role for them that is remarkably similar to Habermas's claims for the paradigm of rational reconstruction. Hence a reinterpretation of transcendentalism provides a new basis for establishing a continuity between his early and later work. Habermas's underlying argument structure (...) owes much, albeit unconsciously, to Kant's concept of a regulative idea. Only the "as if" status of regulative ideas allows one to make sense of the metacritical structure of KHI and Habermas's transcendental arguments emerge as deeply hermeneutic in character rather than logical in any formal sense.

The possibility of a human head transplant poses unprecedented philosophical and neuroethical questions. Principal among them are the personal identity of the resultant individual, her metaphysical and social status: Who will she be and how should the “new” person be treated - morally, legally and socially - given that she incorporates characteristics of two distinct, previously unrelated individuals, and possess both old and new physical, psychological, and social experiences that would not have been available without the transplant? We contend that (...) this situation challenges linguistic conventions and conceptual binaries, and calls into question the major philosophical approaches to personal identity: animalism and reductionism. We examine these views critically vis-a-vis head transplantation and conclude that they fail to provide an adequate account of the identity of the resultant individual because both neglect the key role of embodiment for personal identity. We maintain that embodiment is central to personal identity and a radical alteration of the body will also radically alter that person, making her a different person. Consequently, a human head transplant will result in an individual partly continuous with the head/brain, and partly continuous with the body donor. We conclude that the resultant person would be different from both the individual whose head was transplanted and the one to whose body the “new” head is attached. (shrink)

The supporter of vague objects has been long challenged by the following ‘Argument from Identity’: 1) if there are vague objects, then there is ontically indeterminate identity; 2) there is no ontically indeterminate identity; therefore, 3) there are no vague objects. Some supporters of vague objects have argued that 1) is false. Noonan (Analysis 68: 174–176, 2008) grants that 1) does not hold in general, but claims that ontically indeterminate identity is indeed implied by the assumption that there are vague (...) objects of a certain special kind (i.e. vague objects*). One can therefore formulate a ‘New Argument from Identity’: 1′) if there are vague objects*, then there is ontically indeterminate identity; 2) there is no ontically indeterminate identity; therefore, 3′) there are no vague objects*. Noonan’s strategy is to argue that premiss 1′) is inescapable, and, as a consequence, that Evans’s alleged defence of 2) is a real challenge for any supporter of vague objects. I object that a supporter of vague objects who grants the validity of Evans’s argument allegedly in favour of 2) should reject premiss 1′). The threat of the New Argument from Identity is thus avoided. (shrink)

According to philosophers who ground your anticipation of future experiences in psychological continuity and connectedness, it is rational to anticipate the experiences of someone other than yourself, such as a self that is the product of fission or of replication. In this article, I concur that it is rational to anticipate the experiences of the product of fission while denying the rationality of anticipating the experiences of a replica. In defending my position, I offer the following explanation of why you (...) have good reason to anticipate the experiences of your post-fission successor but not your replica: in the former case, you become somebody else, whereas, in the latter case, you are merely replaced by somebody else.

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)

Jacob Ross argues that the fission cases discussed in the personal identity literature cannot be accommodated without rejecting basic intuitions of everyday ethical thinking. He notes that many philosophers have responded to the challenge of fission ‘by rejecting the metaphysical assumptions on which it rests’. In particular, that many have denied that in fission one ceases to exist. He contends that these denials do not meet the challenge to commonsense ethical thinking. I reject these claims. One of the metaphysical views (...) he considers is the multiple occupancy view of Lewis and Robinson, according to which in fission there are all along two numerically distinct, initially collocated, persons. I claim that Ross has not shown that this view has counterintuitive ethical implications. (shrink)

Williams's famous thought experiment in "The Self and the Future" supports the Simple View of personal identity over time.

When one considers one's own persistence over time from the first-person perspective, it seems as if facts about one's persistence are "further facts," over and above facts about physical and psychological continuity. But the idea that facts about one's persistence are further facts is objectionable on independent theoretical grounds: it conflicts with physicalism and requires us to posit hidden facts about our persistence. This essay shows how to resolve this conflict using the idea that imagining from the first-person point of (...) view is a guide to centered possibility, a type of possibility analyzed in terms of centered worlds.

According to one argument for Animalism about personal identity, animal , but not person , is a Wigginsian substance concept—a concept that tells us what we are essentially. Person supposedly fails to be a substance concept because it is a functional concept that answers the question “what do we do?” without telling us what we are. Since person is not a substance concept, it cannot provide the criteria for our coming into or going out of existence; animal , on the (...) other hand, can provide such criteria. This argument has been defended by Eric Olson, among others. I argue that this line of reasoning fails to show Animalism to be superior to the Psychological Approach, for the following two reasons: (1) human animal , animal , and organism are all functional concepts, and (2) the distinction between what something is and what it does is illegitimate on the reading that the argument needs.

Many philosophers believe that the criteria of identity over time for ordinary objects entail that such objects are permanent members of certain sortal kinds. The sortal kinds in question have come to be known as substance sortal kinds.

The criterion I defend is a sortal‐weighted version of a change‐minimizing criterion first discussed by Eli Hirsch. (...) I present this criterion and then argue that it withstands attempts to show that it is inferior to non‐phasalist rivals. (shrink)

According to the Psychological Account of personal identity, personal identity across time is maintained by some form of psychological overlap or continuance. I show that the Psychological Account has trouble accommodating cases of transient retrograde amnesia. In such cases, the transitivity of psychological continuity may break down. I consider various means of responding to this problem, arguing that the best available response will undercut our ability to rely on intuitions about brain transplantation to support the Psychological Account. When the Psychological (...) Account is re-interpreted in such a way as to overcome the problems posed by cases of transient retrograde amnesia, it turns out that standard brain transplantation cases involve details which are strictly irrelevant according to the theory. On the other hand, these features seem to drive our intuitions about survival in these cases. In this way, my argument undermines one of the key motivations for adopting the Psychological Account.

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.

ABSTRACTOne of the most significant features of Wittgenstein's Remarks on the Philosophy of Psychology is his reflections on emotions. Wittgenstein's treatment of this topic was developed in direct response to his reading of William James’s chapter on emotions in his 1890 masterpiece, The Principles of Psychology. This paper examines the competing views of emotions that emerge in these works, both of which attempt to overcome the Cartesian dualist conception in different ways. The main point of disagreement concerns the relation between (...) emotions and their bodily expression. My interpretation focuses on Wittgenstein's remarks on the emotion of love because, I argue, it is a particularly problematic case. To elucidate his largely unexplored view of love, I draw on his remarks on understanding and criteria in the Philosophical Investigations. I argue that by examining the examples of comple... (shrink)
