Depersonalization is a pathological condition consisting in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, his mind and even from himself. In this article, I argue that the study of depersonalization raises three challenges for recent theories of the sense of bodily ownership. These challenges—which I call the centrality challenge, the dissociation challenge and the grounding challenge— thwart most of these theories and suggest that the (...) sense of bodily ownership hinges on a phenomenal mark of mineness that can not be accounted for in terms of our sensory, interoceptive, agentive, cognitive or affective dispositions and that is psychologically primitive. In short: that mineness is first. (shrink)

In a previous article on cosmological arguments, I have put forward a few examples of complete infinite and circular explanations, and argued that complete non-wellfounded explanations such as these might explain the present state of the world better than their well-founded theistic counterparts (Billon, 2021). Although my aim was broader, the examples I gave there implied merely causal explanations. In this article, I would like to do three things: • Specify some general informative conditions for complete and incomplete non-wellfounded causal (...) explanations that can be used to assess candidate explanations and to generate new examples of complete non-wellfounded explanations. • Show that these conditions, which concern chains of causal explanations, easily generalize to chains of metaphysical, grounding explanations and even to chains involving other “determination relations” such as supervenience. • Apply these general conditions to the recent debates against the existence of nonwellfounded chains of grounds and show, with a couple of precise examples, that the latter can be complete, and that just like in the case of causal explanations, non-wellfoundedness can in fact be an aset rather than a liability.

We examine how Frege’s contrast between identity judgments of the forms “a=a” vs. “a=b” would fare in the special case where ‘a’ and ‘b’ are complex mental representations, and ‘a’ stands for an introspected ‘I’-thought. We first argue that the Fregean treatment of I-thoughts entails that they are what we call “one-shot thoughts”: they can only be thought once. This has the surprising consequence that no instance of the “a=a” form of judgment in this specific case comes out true, let (...) alone a priori true. This further reinforces Glezakos’s objections against the set-up of Frege’s puzzle, while also raising what we think is an acute problem for Fregeans, insofar as I-thought (and indexical thinking more generally), understood in their way, turns out to be incompatible with some basic features of rationality.

Patients suffering from depersonalization complain of feeling detached from their body, their mental states, and actions or even from themselves. In this chapter, I argue that depersonalization consists in the lack of a phenomenal feature that marks my experiences as mine, which is usually called “mineness,” and that the study of depersonalization constitutes a neglected yet incomparable probe to assess empirically the scope, role, and even the nature of mineness. Here is how I will proceed. After describing depersonalization (§2) and (...) arguing that it involves a lack of mineness (§3) I will confront a series of objections (§4). I will then spell out what depersonalization can teach us about the scope of mineness (§5), about its role and psychological function (§6) and even about its nature (§7). (shrink)

Most of what has been written about Buber and education tend to be studies of two kinds: theoretical studies of his philosophical views on education, and specific case studies that aim at putting theory into practice. The perspective taken has always been to hold a dialogue with Buber's works in order to identify and analyse critically Buber's views and, in some cases, to put them into practice; that is, commentators dialogue with the text. In this article our aims are of (...) a different kind. First and fundamentally, we demonstrate the political and social ontological basis of Buber's thought; that is, we show that Buber, the philosopher of dialogue, held an authentic dialogue with his time, and demonstrate that Buber's work, in this case I and Thou, holds a dialogue with its Zeitgeist; that is the text dialogues with its Zeitgeist. This approach leads us to our second aim, which is to demonstrate that Buber's thought remains relevant to our times, particularly when it serves as a dialogical educational tool with which to resolve conflict of all types and to aid dialogue towards peace in inter‐community relations.

Depersonalization consists in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, and his mind, and even from himself. Even though, when it was discovered at the end of the 19th century, this psychiatric condition was widely used to probe certain aspects of bodily awareness, and more specifically the sense of bodily ownership (SBO), it has been strangely neglected in contemporary debates. In this chapter, I argue (...) that because of three specific features, depersonalization raises some important challenges for current theories of the SBO. The first feature — call it “generality” — is that depersonalization does not only affect the sense of bodily ownership but also, typically, the sense of ``mental ownership’’ (SMO), the sense of agency or ``action ownership’’ (SOA), and the subject’s core sense of herself (CSS), that is, her awareness of herself as an I. The second feature is that except for the symptoms of depersonalization, depersonalized patients are hard to distinguish, psychologically, from normal subjects. This makes it hard to find psychological features that might explain their condition. The last feature, call it “fundamentality” is that the psychological features that do seem abnormal among depersonalized patients seem more likely to be explained by depersonalization than to explain it. These three features raise three challenges — the centrality challenge, the dissociation challenge, and the grounding challenge. Taken together, I will argue, these challenges suggest that the SBO depends on a form of phenomenal “mineness” that would mark my mental states as mine and that cannot be accounted for in sensorimotor, cognitive, or even affective terms. A phenomenal mineness that indeed seems to be psychologically primitive, and only accountable in neurophysiological terms. (shrink)

In this article I interpret John Rawls’s concept of the original position as a spiritual exercise. In addition to the standard interpretation of the original position as an expository device to select principles of justice for the fundamental institutions of society, I argue that Rawls also envisages it as a “spiritual exercise”: a voluntary personal practice intended to bring about a transformation of the self. To make this argument, I draw on the work of Pierre Hadot, a philosopher and classicist, (...) who introduced the idea of spiritual exercises as central to ancient and modern conceptions of philosophy. By reading Rawls alongside Hadot, this article portrays Rawls as a thinker deeply concerned with the question of how subjects can lead more just and fulfilling lives. It also proposes that the original position as a spiritual exercise can help defend liberalism as a social and political doctrine. (shrink)

Patients suffering from the Cotard syndrome can deny being alive, having guts, thinking or even existing. They can also complain that the world or time have ceased to exist. In this article, I argue that even though the leading neurocognitive accounts have difficulties meeting that task, we should, and we can, make sense of these bizarre delusions. To that effect, I draw on the close connection between the Cotard syndrome and a more common condition known as depersonalisation. Even though they (...) are not delusional, depersonalised patients seem to have experiences that are quite similar to those of Cotard patients. I argue that these experiences are essentially characterised by a lack of subjective character and of two other structural features of experience, which I call ‘the present character’ and ‘the actual character’. Cotard's nihilistic delusions simply consist in taking these anomalous experiences at face value. (shrink)

This is a commentary on Andrea Lavazza and Murilo Vilaça's article "Human Extinction and AI: What We Can Learn from the Ultimate Threat" (Lavazza & Vilaça, 2024). I discuss the potential concern that their proposal to create artificial successors to "insure" against the tragedy of human extinction might mean being too quick to accept that catastrophic prospect as inevitable, rather than single-mindedly focusing on avoiding it. I also consider the question of the value that we might reasonably assign to such (...) a future of artificial successors under the assumption that they do not enjoy phenomenal consciousness.

Fichte is the first great Post-Kantian Idealist and his debt to Spinozism has been acknowledged by virtually all of his commentators. However, the extent of Spinoza’s influence on Fichte has not been spelled out in much detail. In response to this I propose to do two things. Firstly, I propose to provide a typology of interpretations of Fichte’s Absolute I, as some commentators seem to get entangled in these different interpretations, which can be very confusing to their readership. Secondly, I (...) wish to demonstrate that the Fichtean system is better understood in the light of its Spinozist influences. (shrink)

I first propose to distinguish between two kinds of external validity inferences, predictive and explanatory. I then argue that we have a satisfactory answer to the question of the conditions under which predictive external validity inferences are good. If this claim is correct, then it has two immediate consequences: First, some external validity inferences are deductive, contrary to what is commonly assumed. Second, Steel’s requirement that an account of external validity inference break what he calls the ‘Extrapolator’s Circle’ is misplaced, (...) at least when it comes to predictive external validity inferences.

Consider an infinite series whose items are each explained by their immediate successor. Does such an infinite explanation explain the whole series or does it leave something to be explained? Hume arguably claimed that it does fully explain the whole series. Leibniz, however, designed a very telling objection against this claim, an objection involving an infinite series of book copies. In this paper, I argue that the Humean claim can, in certain cases, be saved from the Leibnizian “infinite book copies” (...) objection, and that this provides an interesting way to defuse some cosmological arguments for the existence of God and to give a non-theistic but complete explanation of the Universe. In the course of my argumentation, I also show that circular explanations can be “self-explanatory” as well: explaining two items by each other can explain the couple of items tout court. (shrink)

Ttler=‘Ttler is true’ says of itself that it is true. It is a truth-teller. I argue that we have equally telling arguments (i) to the effect that all truth-tellers must have the same truth-value (ii) and the effect that truth-tellers differ in truth-value. This is what I call the Truth-Tellers paradox. This paradox stems from the fact that the truth-value of a truth-teller like Ttler should be determined by the fact that it says of itself that it is true (which (...) entails (i)) but that it cannot be determined by that fact (as witnessed by (ii)). The Truth-Tellers paradox resem- bles the classical semantic paradoxes like the Liar. In both cases, a form of self-reference allows us to derive a contradiction from oth- erwise plausible semantic and logical principles. Furthermore the Truth-Tellers paradox can be formulated without using sentences which are in an intuitive sense ungrounded, it thus severs the link, almost universally taken for granted, between the semantic para- doxes and ungroundedness. Finally, some classical solutions to the Liar do not generalize to the Truth-Tellers paradox. (shrink)

One objection to enhancement technologies is that they might lead us to live inauthentic lives. Memory modification technologies (MMTs) raise this worry in a particularly acute manner. In this paper I describe four scenarios where the use of MMTs might be said to lead to an inauthentic life. I then undertake to justify that judgment. I review the main existing accounts of authenticity, and present my own version of what I call a “true self” account (intended as a complement, rather (...) than a substitute, to existing accounts). I briefly describe current and prospective MMTs, distinguishing between memory enhancement and memory editing . Moving then to an assessment of the initial scenarios in the light of the accounts previously described, I argue that memory enhancement does not, by its very nature, raise serious concerns about authenticity. The main threat to authenticity posed by MMTs comes, I suggest, from memory editing. Rejecting as inadequate the worries about identity raised by the President’s Council on Bioethics in Beyond Therapy , I argue instead that memory editing can cause us to live an inauthentic life in two main ways: first, by threatening its truthfulness, and secondly, by interfering with our disposition to respond in certain ways to some past events, when we have reasons to respond in such ways. This consideration allows us to justify the charge of inauthenticity in cases where existing accounts fail. It also gives us a significant moral reason not to use MMTs in ways that would lead to such an outcome. (shrink)

Descartes was certain that he was thinking and he was accordingly certain that he existed. Like Descartes, we seem to be more certain of our thoughts and our existence than of anything else. What is less clear is the reason why we are thus certain. Philosophers throughout history have provided different interpretations of the cogito, disagreeing both on the kind of thoughts it characterizes and on the reasons for its cogency. According to what we may call the empiricist interpretation of (...) the cogito, I can only claim to be certain of having experiences, and this certainty, as well as that of my own existence, stems from their phenomenal and subjective character. According to rationalist interpretations, on the other hand, I am certain of having some self-reflexive propositional attitudes, and this certainty derives from their rational features. Psychiatric patients suffering from acute forms of depersonalization or of the Cotard syndrome often doubt that they think and exist, and might even believe that they don't. I argue that their study allows us to favor the empiricist interpretation of the cogito. (shrink)

Gilbert and colleagues are to be commended for drawing our attention to the need for a sounder empirical basis, and for more careful reasoning, in the context of the neuroethics debate on Deep Brain Stimulation (DBS) and its potential impact on the dimensions of personality, identity, agency, authenticity, autonomy and self (PIAAAS). While acknowledging this, this extended commentary critically examines their claim that the real-world relevance of the conclusions drawn in the neuroethics literature is threatened by the fact that the (...) concepts at the center of the discussion have “weak empirical grounding”. First, I show that while some possible understandings of multifaceted concepts like identity, authenticity and autonomy may indeed be unsuitable for a purely empirical inquiry, this is not the case of all of them. Secondly, I call into question the authors’ apparent suggestion that reliance on constructs involving an irreducibly normative dimension makes for a suboptimal state of affairs, and that they should ideally be replaced with substitutes taken from the language of neuroscience or social science in order to ensure an adequate empirical grounding for the debate. Such a suggestion, I argue, commits the authors to a controversial reductionist view in metaethics that the valid empirical concerns they raise in the rest of their article do not presuppose, and which could potentially us lead to lose sight of important ethical considerations.

A recent proposal by Norton (2003) to show that a simple Newtonian system can exhibit stochastic acausal behavior by giving rise to spontaneous movements of a mass on the dome of a certain shape is examined. We discuss the physical significance of an often overlooked and yet important Lipschitz condition the violation of which leads to the existence of anomalous nontrivial solutions in this and similar cases. We show that the Lipschitz condition is closely linked with the time reversibility of (...) certain solutions in Newtonian mechanics and the failure to incorporate this condition within Newtonian mechanics may unsurprisingly lead to physically impossible solutions that have no serious metaphysical implications. ‡I thank Steven Savitt of the Philosophy Department at the University of British Columbia for drawing my attention to the Lipschitz condition, and Alexei Cheviakov of the Mathematics Department at the University of British Columbia for useful discussions. †To contact the author, please write to: Department of Philosophy, University of British Columbia, Vancouver, BC, V6T 1Z1, Canada; e-mail: [email protected].

In their target article, Kammerer and Frankish (K&F) wonder what forms introspection could take in non-human animals, enhanced humans, artificial intelligences, and aliens. In this short note, I focus on disordered or neurodiverse minds. More specifically, I assess a claim that has often been made more or less implicitly to the effect that, in virtue of their conditions, people with schizophrenia or depersonalization disorder have superior introspective abilities that allow them to discern some important but normally hidden characteristics of our (...) experiences — call this the superintrospectionitis thesis. In the course of my argumentation, I introduce distinctions and questions concerning the nature of the architecture and the function of introspection that might enrich K&F's framework. (shrink)

Basic self-awareness is the kind of self-awareness reflected in our standard use of the first-person. Patients suffering from severe forms of depersonalization often feel reluctant to use the first-person and can even, in delusional cases, avoid it altogether, systematically referring to themselves in the third-person. Even though it has been neglected since then, depersonalization has been extensively studied, more than a century ago, and used as probe for understanding the nature and the causal mechanisms of basic self-awareness. In this paper, (...) I argue that depersonalized patients indeed have an impaired basic self-awareness, and that their study allows us both to favor one specific theory of basic self-awareness and to understand what is wrong with its rivals. According to the favored theory, which I call Cartesian, we are basically self-aware in virtue of being acquainted with ourselves through introspection. (shrink)

Many philosophers regard the persistence of philosophical disputes as symptomatic of overly ambitious, ill-founded intellectual projects. There are indeed strong reasons to believe that persistent disputes in philosophy (and more generally in the discourse at large) are pointless. We call this the pessimistic view of the nature of philosophical disputes. In order to respond to the pessimistic view, we articulate the supporting reasons and provide a precise formulation in terms of the idea that the best explanation of persistent disputes entails (...) that they are pointless. We then show how to answer the pessimistic argument. Taking a well-known mathematical controversy as our paradigm example, we argue that some persistent disputes reflect substantive disagreements at the “meta-analytic” level, i.e., disagreements about the best way, among quite different candidates, to understand the topic at issue, and the best associated cluster of analytic truths one should accept concerning it. Moreover, our concrete example shows that such meta-analytic disagreements can in principle be settled and yield a genuine theoretical (as opposed to merely pragmatic) breakthrough. We conclude optimistically that persistent disputes can be an important means of fostering epistemic progress. (shrink)

Le problème du partage des bénéfices liés aux ressources naturelles ne peut faire l’économie de la question territoriale. Cette question est de plus en plus abordée sous l’angle des droits territoriaux sans toutefois reposer sur une théorie générale de la territorialité qui permettrait d’éviter l’écueil de l’ethnocentricité. Nous proposons donc une définition fonctionnaliste de la territorialité permettant de distinguer des territorialités matérielles et idéelles, des territoires formels et fonctionnels, et des conceptions verticale et horizontale du territoire. Ces distinctions nous permettent (...) de formuler une question fondamentale que la philosophie politique a trop peu abordée : comment gérer la concurrence des légitimités territoriales dans un même espace ?The problem of how to share the benefits generated from the extraction of natural resources is directly linked to territorial issues. These issues have been increasingly addressed from a perspective of territorial rights without, however, developing a theory of territoriality that would avoid the risk of ethnocentrism. I thus propose a functionalist definition of territoriality that would allow for a distinction between two types of territoriality , two kinds of territories , and two different conceptions of territory . These distinctions lay the groundwork for formulating a fundamental question that has been neglected by political philosophy — how should concurrent territorial legitimacies be managed ? — and provide us with the conceptual tools to tackle it.

The neural correlates of two hypothesized emotional processing modes, i.e., schematic and propositional modes, were investigated with positron emission tomography. Nineteen subjects performed an emotional mental imagery task while mentally repeating sentences linked to the meaning of the imagery script. In the schematic conditions, participants repeated metaphoric sentences, whereas in the propositional conditions, the sentences were explicit questions about specific emotional appraisals of the imagery scenario. Five types of emotional scripts were proposed to the subjects (happiness, anger, affection, sadness, and (...) a neutral scenario). The results supported the hypothesized distinction between schematic and propositional emotional processing modes. Specifically, schematic mode was associated with increased activity in the ventromedial prefrontal cortex whereas propositional mode was associated with activation of the anterolateral prefrontal cortex. In addition, interaction analyses showed that schematic versus propositional processing of happiness (compared with the neutral scenario) was associated with increased activity in the ventral striatum whereas “schematic anger” was tentatively associated with activation of the ventral pallidum. © 2003 Elsevier Science (USA).

In this paper, I will look at the relationship between Weitz’s claim that art is an “open” concept and Dickie’s institutional theory of art, in its most recent form. Dickie’s theory has been extensively discussed, and often criticized, in the literature on aesthetics, yet it has rarely been observed – to my knowledge at least – that the fact that his theory actually incorporates, at least to some extent, Weitz’s claim about the “openness” of the concept of art, precisely accounts (...) for what I take to be the main flaws in the theory. In what follows I present arguments for that claim, looking briefly at the position of both authors with respect to the concept of art, then showing how they relate to each other, and what implications this has for Dickie’s institutional theory, and more generally for the traditional project of characterising art.

Advocates of the counterfactual approach to causal inference argue that race is not a cause, and this despite the fact that it is commonly treated as such by scientists in many disciplines. I object that their argument is unsound since two of its premises are false.

Most paradoxes of self-reference have a dual or ‘hypodox’. The Liar paradox (Lr = ‘Lr is false’) has the Truth-Teller (Tt = ‘Tt is true’). Russell’s paradox, which involves the set of sets that are not self-membered, has a dual involving the set of sets which are self-membered, etc. It is widely believed that these duals are not paradoxical or at least not as paradoxical as the paradoxes of which they are duals. In this paper, I argue that some paradox’s (...) duals or hypodoxes are as paradoxical as the paradoxes of which they are duals, and that they raise neglected and interestingly different problems. I first focus on Richard’s paradox (arguably the simplest case of a paradoxical dual), showing both that its dual is as paradoxical as Richard’s paradox itself, and that the classical, Richard-Poincaré solution to the latter does not generalize to the former in any obvious way. I then argue that my argument applies mutatis mutandis to other paradoxes of self-reference as well, the dual of the Liar (the Truth-Teller) proving paradoxical. (shrink)

Spinoza, according to common opinion, could only have written lamentable platitudes on sexual love, narrowly inspired by the prejudices of his time and without serious philosophical foundation: that for which, in the past, he has been congratulated,1 he is now reproached; or, at best, excused. He would even have, some believe to be able to add, increased the pervading puritanism: sexuality, as such, would give rise in him to a deep repulsion and women would horrify him. The second of these (...) two assertions, if one sticks to the manifest content of the texts, actually rests on nothing; if one calls upon their latent content, it would require, to be established with a minimum of rigor, a study of which we will not dispute the theoretical possibility, but which, in fact, has not yet been undertaken. The first, on the other hand, has all the appearance of the obvious: that men love women for their beauty and do not support their attachment to someone else,2 that they desire them more the more admirers they have,3 that the jealousy of the male is exacerbated by the representation of the pudenda and of the excrementa of his rival,4 that sensual attachment is unstable and conflictual,5 that it often turns to obsession,6 that Adam loved Eve because of their similarity of nature,7 that he who remains insensitive to the generosity of a courtesan does not offend by ingratitude,8 that only free men and free women can marry one another and only if they want children,9 well, it seems, that isn’t anything sensational; now these eight passages, if the two definitions of the libido are added to them,10 are the only, if I’m not mistaken, that Spinoza expressly devoted to the question! He would therefore, apparently, only have drawn up a report of deficiency. (shrink)

There has been a shift from teaching to learning, the so-called process of ‘learnification’, which promotes the idea that teaching should be primarily concerned with the creation of rich learning environments and scaffolding student learning. In doing so, this process of ‘learnification’ has also attacked the idea that teachers have something to teach and that students have something to learn from their teachers. The influence of constructivism, and thinkers like Piaget, Vygotsky, and Bruner in this paradigm shift is quite evident; (...) however, this gives rise to a tension in what a teacher is and what teaching entails, because the teacher, by definition, is someone who has something to teach students, and not merely a facilitator of the learning process. Moreover, because of constructivism and ‘learnification’, current educational practices and policies seem to pay little attention to the importance of ‘relations’ and ‘the encounter with the Other’, which become merely desirable by-products. In this article I criticise constructivism and ‘learnification’ by proposing that the teacher is a community ‘builder’ and teaching a ‘situational revelation’, while also emphasising the importance of ‘relations’ in the educational process. The starting point for my discussion is a much neglected passage of I and Thou where Martin Buber discusses the importance of the ‘living centre’ [lebendigen Mitte] for ‘true community’ [Die wahre Gemeinde] formation.

TOPOGRAPHICAL MISSIONS ΤΟ LATO I (2005-2007): A CRITICAL ANALYSIS OF THE PLAN BY J. DEMARGNE AND V. SEYK (1901) In the years 2005 and 2007 the site of Lato in Crete was the object of three new topographical and geomorphological study campaigns. The works carried out over the entire site permitted in particular the analysis of the only to date available complete plan of the city, that of J. Demargne and the architect V. Seyk undertaken in 1900. The objectif was (...) to establish its documentary interest and limits in use, and thus better prepare new measurements and guide renewed field work. To do this, it was first necessary (I) to retrace the history of previous graphic documentation, (II) to analyse the work of J. Demargne and V. Seyk, so as (III) to gauge its value against the standards of current research, and (IV) to establish its interest in terms of the cultural resource management of the site. A second paper to appear in BCH will develop, on basis of a new documentation, the urban and morphological analysis of the remains of Lato. (shrink)

According to David Chalmers, the virtual entities found in Virtual Reality (VR) and Augmented Reality (AR) environments instantiate virtual properties of a specific kind. It has recently been objected that such a view (i) can’t extend to all types of properties; (ii) leads to a proliferation of property-types; (iii) implausibly ascribes massive errors to VR and AR users; and (iv) faces an analogue of Jackson’s “many-property problem”. My first objective here is to show that advocates of virtual properties can deal (...) with each of these objections. The other goal of this paper is to examine the consequences of Chalmers’ theory in the particular case of AR. If we countenance virtual properties, AR highlights that non-virtual objects can possess both non-virtual and virtual properties. With AR, it also appears that a same non-virtual object can have different and even incompatible properties across augmented environments. Lastly, considering properties in light of AR highlights the risk of an “augmented solipsism”, and calls forth interesting questions about the persistence conditions of non-virtual objects in AR environments.

This paper considers the medium of videogames from a goodmanian standpoint. After some preliminary clarifications and definitions, I examine the ontological status of videogames. Against several existing accounts, I hold that what grounds their identity qua work types is code. The rest of the paper is dedicated to the epistemology of videogaming. Drawing on Nelson Goodman and Catherine Elgin's works, I suggest that the best model to defend videogame cognitivism appeals to the notion of understanding.

Open Peer Commentary on P. Zawadzki and A. K. Adamczyk's target article in AJOB Neuroscience on the potential of optogenetics for memory modification.

I focus on the method designed by the young Leibniz in order to analyze specific legal modalities, the so-called suspensive conditions. Such a method, to analyze the specific conditionals whose if-part is a suspensive condition, gives Leibniz access to the resources of logical analysis of conditionals. I show that the contribution of logic to the law goes hand in hand with an extended complication of the former thanks to which Leibniz achieves at capturing a number of dynamical features of suspensive (...) conditions, but also of resolutory and temporal legal modalities.

Many believe that the treatment-enhancement distinction marks an important ethical boundary that we should use to shape public policy on biomedical interventions. A common justification for this purported normative force appeals to the idea that, whereas treatments respond to genuine medical needs, enhancements can only satisfy mere preferences or “expensive tastes”. This article offers a critique of that justification, while still accepting the TED as a conceptual tool, as well as some of the key ethical axioms endorsed by its proponents. (...) I begin by laying out the TED, the practical implications that tend to be drawn from it, and the justification just sketched for these implications. Using examples drawn from preventive medicine, biomedical technology, and other categories of biomedical interventions, I then go on to challenge both the presupposition of a fundamental dichotomy between treatments and enhancements, and the assumption that enhancements – barring rare exceptions – cannot serve legitimate medical needs. Finally, I consider some ways in which supporters of the TED might try re-formulating the distinction to blunt the force of my critique. I conclude that such a move cannot fully succeed, and that while the TED does have some degree of normative force, it nevertheless cannot play the role that its advocates expect from it. Seeking to justify a general presumption against enhancements based on the rationale I critique here would mean ignoring their various potential benefits, including medical or therapeutic, and would reflect a prejudice – which I refer to as “treatment fetishism”.
