Physical and Animalist Theories Of Personal Identity

Recent decades have seen an increasing tendency to exclude the phenomenon of personality from the metaphysical investigation of personal identity. We are advised not to confuse personal identity as a philosophical subject, namely as the metaphysical issue of specifying what it is that makes a person staying numerically self-identical over time, with the psychological question of 'personal identity' which asks what makes someone the individual person they are with their particular character and history. However, one might be unsatisfied with this. (...) If (as common sense takes for granted) persons are to be conceived as beings possessing a personality, should there not be some more than superficial connection between personality and personal identity in the philosophical sense? This paper investigates this question by revealing the guiding - metaphysical assumptions behind the claim that personality and personal identity must be treated separately as well as by presenting the metaphysical alternative brushed aside by the adherents of this claim. In fact, I argue, there are two opposing views of the relation between personality and personal identity, these being grounded in two opposing metaphysical models of what a person is: the substance model and the bundle model of the person. However, it turns out that ultimately both competing models fail for fundamental reasons, which raises the question of what a way out of the dilemma might look like. (shrink)

Eric Olson distinguishes his animalistic account of transtemporal personal identity from the apparently similar Bodily Criterion, among other things, by accusing the latter of being contaminated with Cartesian implications owing to its usage of the term ‚body‘. In contrast, Olson argues, Animalism is able to avoid these implications by substituting the concept of body for the concept of organism, which makes Animalism not only a distinct position, but also the better alternative to the Bodily Criterion. The paper critically reconstructs Olson’s (...) charge of Cartesianism against the Bodily Criterion, thereby differentiating between several variants of it. This eventually adds up to an evaluation of how suitable these criticisms are for defending Animalism at the expense of the Bodily Criterion. (shrink)

Können wir als Personen irreversible Gedächtnisverluste überleben? Wie steht es mit Teletransportationen? Wie mit jahrelangem Einfrieren? Fragen wie diese sind weit davon entfernt, bloße Denksportaufgaben für Science-Fiction-Fans zu sein. Vielmehr verraten uns Antworten darauf, welche unserer Eigenschaften uns wirklich wichtig sind und was unser Wesen ausmacht. -/- Unglücklicherweise beantworten Vertreter unterschiedlicher Theorien personaler Identität diese Fragen auf völlig verschiedene Weise. Manche schöpfen die Plausibilität ihrer Positionen aus phantasievollen Gedankenexperimenten; anderen sind dieselben Gedankenexperimente für eine ernsthafte Einbeziehung in die philosophische Theoriebildung (...) schlicht zu wirklichkeitsfern. Es überrascht daher kaum, dass jene Anhänger unterschiedlicher Theorien einander oft wenig zu sagen haben. Im ersten Teil des Buches wird untersucht, unter welchen Umständen Gedankenexperimente aussagekräftige philosophische Werkzeuge sind. Auf der Basis dieser Analyse werden die diversen zeitgenössischen Theorien personaler Identität dann im zweiten Teil einer Neubewertung unterzogen – nicht ohne dass dabei mit vielen selbstverständlich erscheinenden Überzeugungen aufgeräumt wird.

Theories of personal identity face a paradox, which traces back to Bernard Williams: some scenarios obviously show that mental continuity is what solely matters in survival; others, on the contrary, show with equal obviousness that it is bodily continuity. Different authors have produced diverging and partly conflicting answers in response to that problem. Based on recent research concerning the structure of philosophical thought experiment, this paper reevaluates and, for the first time, neatly classifies those answers. What is more, several existing (...) approaches of how to answer the paradox are developed further, and two new answers are introduced. (shrink)

The problem of defining the self has traditionally been conceived as a task for philosophers. However, the development of immunology in the second part of the 20th century has led many scientists to conclude that immunology is the science of the self. This led to two different approaches to biological individuality: physiological individuation that is mostly concerned with organisms seen as strongly cohesive and unified metabolic entities, and evolutionary individuation where evolution by natural selection is seen as the best framework (...) for individuating biological entities. I discuss physiological approaches to biological individuation with a special focus on the immunological theories of the self. I argue that the immunological theories can only function as vague metaphors that do not provide a valid criterion for individuating organisms in biology. (shrink)

În acest eseu evidențiez principalele aspecte psihologice și filosofice desprinse din filmul Solaris regizat de Andrei Tarkovski, precum și tehnicile cinematografice utilizate de regizor pentru a-și transmite mesajele spectatorului. În ”Introducere” prezint pe scurt elementele relevante din biografia lui Tarkovski și o prezentare generală a romanului Solaris a lui Stanislav Lem și filmul Solaris în regia lui Andrei Tarkovsky. În ”Tehnica cinematografică” vorbesc despre ritmul specific al scenelor, mișcarea radicală declanșată de Tarkovsky în cinematografia modernă, rolul elementelor simbolice și iconice, (...) , și afinitățile cu zona fantastică a literaturii ruse. În ”Aspecte psihologice” analizez problema comunicării într-o societate umană a viitorului considerată de Tarkovsky ca rigidă, obsesia casei, și evoluția personală a lui Kris, Hari, și a relațiilor dintre ei. În ”Aspecte filosofice” se analizează filmul prin prisma filosofiei minții (dualismul cartezian, reducționismul și funcționalismul), a problemei identității personale, a teoriei spațiilor heterotopice dezvoltată de Michel Foucault, și interpretările semantice care se pot deduce din film. De asemenea, se analizează problema identității personale prin prisma filosofiei lui Locke. ”Concluziile” expun ideile generale rezultate din acest eseu, respectiv că Tentativele omului de a clasifica și de a păstra forme de interacțiune cu entități necunoscute vor fi întotdeauna condamnate la eșec și vor reflecta o greșeală majoră în lumea panoptică în care trăim. În acest cadru de analiză a filosofiei minții, funcționalismul pare a fi cel mai intuitiv. Solaris este, totuși, un film care începe ca o căutare a răspunsurilor și ajunge să ofere aceste răspunsuri împreună cu o serie de întrebări cu totul diferite. (shrink)

The topic of this paper is the general thesis that the death of the human organism is what constitutes the death of a person. All admit that when the death of a human organism occurs, in some form or another, this normally does result in the death of a person. But, some maintain, organismic death is not the same thing as personal death. Why? Because, they maintain, despite the fact that persons are associated with a human organism (‘their organism’), they (...) are not identical with their organism, and so they can, at least in principle and perhaps in actuality, die before or after their organism dies. The thesis described above I shall call ‘the two-deaths thesis’ in virtue of the fact that its proponents believe that there are two kinds of death, viz. organismic death and personal death. The opposing thesis, according to which the death of a human organism does constitute the death of a person, I call the ‘one death thesis’. After giving some background remarks in section 2 of this paper, in section 3 I argue that, if we take linguistic usage seriously, neither the two-deaths thesis nor the one-death thesis is true. I argue, rather, that so far as linguistic usage goes it is indeterminate which of them is true. In section 4 I go further and argue that if one accepts a widely held metaphysical view, viz. that the world itself partially determines reference and the extensions of our concepts, then it is plausible that the one-death thesis is true despite the facts about linguistic usage.

This article, the first of a two-part essay, presents an account of Aristotelian hylomorphic animalism that engages with recent work on neuroscience and philosophy of mind. I show that Aristotelian hylomorphic animalism is compatible with the new mechanist approach to neuroscience and psychology, but that it is incompatible with strong emergentism in the philosophy of mind. I begin with the basic claims of Aristotelian hylomorphic animalism and focus on its understanding of psychological powers embodied in the nervous system. Next, I (...) introduce the new mechanist approach to neuroscience and psychology and illustrate how it can enrich the more abstract ontological framework of Aristotelian hylomorphic animalism. In the third section of this article I establish in detail the many ways Aristotelian hylomorphic animalism is incompatible with strong emergentism in the philosophy of mind. Based on these fundamental differences I show why a criticism leveled against emergentism by the new mechanist philosophy does not hamper my proposed rapprochement between hylomorphism and the new mechanist philosophy. This conclusion, however, leaves untouched the problem I address in the second article, namely, is the new mechanist philosophy compatible with Aristotelian philosophical anthropology’s contention that intellectual operations are immaterial and interact with the psychosomatic operations of the rational animal?

One of the main problems of personal identity is supposed to be how we relate to our bodies. A few philosophers endorse what is called a 'bodily criterion of personal identity': they say that we are our bodies, or at any rate that our identity over time consists in the identity of our bodies. Many more deny this--typically on the grounds that we can imagine ourselves coming apart from our bodies. But both sides agree that the bodily criterion is an (...) important view which anyone thinking about personal identity must consider. (shrink)

Sydney Shoemaker has argued that, because we can imagine a people who take themselves to survive a 'brain-state-transfer' procedure, cerebrum transplant, or the like, we ought to conclude that we could survive such a thing. I claim that the argument faces two objections, and can be defended only by depriving it any real interest.

What are we? What is the nature of the human person? Animalism has a straightforward answer to these long-standing philosophical questions: we are animals. After being ignored for a long time in philosophical discussions of our nature, this idea has recently gained considerable support in metaphysics and philosophy of mind. Containing mainly new papers as well as two highly important articles that were recently published elsewhere, this volume's contributors include both emerging voices in the debate and many of those who (...) have been instrumental in shaping it. Some of their contributions defend animalism, others criticize it, still others explore its more general implications. The book also contains a substantial introduction by the editors explaining what animalism is, identifying leading issues that merit attention, and highlighting many of the issues that the contributors have raised.

Animalism claims that we are animals, i.e. biological organisms of the primate species Homo sapiens. If there is a case in which the number of persons differs from the number of organisms, then animalism is false. Timothy Campbell and Jeff McMahan hold that there are, at least, two such cases: the dicephalus and the cephalopagus conjoined twinning cases. Recently, Eric Olson argued that either Campbell and McMahan's arguments assume the point at issue, rely on undefended assumptions, or constitute paradigmatic anti-animalist (...) claims. After characterising animalism, we address Campbell and McMahan's arguments and Olson's replies. We endorse Olson's first general objection and reject the second and third, nonetheless concluding that animalism isn't undermined by conjoined twinning cases. (shrink)

The reduplication argument advanced by Bernard Williams in 1956 has greatly stimulated the contemporary debate on personal identity. The argument relies on a famous thought experiment that, although not new in the history of philosophy, has engaged some of the most influential contemporary philosophers on the topic. I propose here an interpretation of the argument and a reconstruction of the early reception that Williams’ paper had in the 6 years immediately after its publication. The works discussed include papers by C. (...) B. Martin, G. C. Nerlich, R. Coburn, and J. M. Shorter. (shrink)

Part of the philosophical interest of the topic of organic individuals is that it promises to shed light on a basic and perennial question of philosophical self-understanding, the question what are we? The class of organic individuals seems to be a good place to look for candidates to be the things that we are. However there are, in principle, different ways of locating ourselves within the class of organic individuals; organic individuals occur at both higher and lower mereological levels than (...) the stereotypical bounded and physiologically unified vertebrate organism. The view that we are organic individuals smaller than the physiological organism is one that has recently been endorsed by Derek Parfit. This paper attempts to resolve a dispute between Parfit’s ‘embodied part’ view and a contrary ‘animalist’ view according to which we are whole organisms. It is explained why a problem of multiple thinkers presents a serious obstacle to a straightforward resolution of this dispute. Parfit’s own strategy for dealing with this obstacle is found to be problematic. However his strategy has a certain general shape, which can be instantiated in a different, and better, specific way. I close in the final section, not with a definite resolution of the dispute, but with illustration of how progress on the question of about which organic individuals we are requires engagement with questions about the nature and function of self-awareness.

In her essay, “People and their Bodies,” Judith Thomson writes an evaluation of several formulations of the psychological criterion for personal identity and attempts a strategy of criticizing each formulation of the psychological theory. This is done in order to conclude that a physical theory must be the only remaining viable sufficient candidate for explaining personal identity that is both necessary and sufficient, despite its theoretical weaknesses. This paper seeks to analyze Thomson's critique and explain why her chosen formulations of (...) psychological criterion are inadequate and easy to refine against some of her rather hasty objections. In addition, counterarguments in favor of an 'impure' psychological criterion for personal identity are presented in the hopes of clarifying the philosophical discourse. (shrink)

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head. But, wanting to be sure of your mathematical insight, you once again think ‘2 + 2 = 4’, this time really meditating on your thought. Now suppose that you're sitting in an empty movie theatre. The lighting is normal (...) and the screen in front of you is blank. Then at some point an image of a peach is flashed on the screen. The image isn't up there for long. In fact, it's only on the screen for what seems like an instant—just long enough for you to see it. These two scenarios are a bit mundane. But, as I will show, reflection on them can yield significant results concerning the nature of persons and their persistence through time. First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (shrink)

Shoemaker maintains that when a functionalist theory of mind is combined with his belief about individuating properties and the well-known cerebrumtransplant thought experiment, the resulting position will be a version of the psychological approach to personal identity that can avoid The Problem of Too Many Thinkers. I maintain that the costs of his solution—that the human animal is incapable of thought—are too high. Shoemaker also has not provided an argumentagainst there existing a merely conscious being that is not essentially self-conscious (...) but is spatially coincident with a person who is essentially self-conscious. Both the person and the merely sentient being will be transplanted when the cerebrum is. And another thought experiment will make it impossible for Shoemaker to identify the person and the merely conscious being. (shrink)

In this essay I explore the idea that the solution to some important problems of personal identity lies in the philosophy of language: more precisely in the nature of first-person reference. I will argue that the “linguistic solution” is at best partly successful.

I consider, and rebut, the argument from "twinning" - that zygotes can't be considered human individuals as two or more such individuals could be (sometimes are) produced from one zygote.

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)

A high level of confidence in the identity of individuals is required to let them die as ordered by an advance directive. Thus, if we are animalists, then we should lack the confidence required to apply lethal advance directives to the cheerfully demented, or so I argue. In short, there is consensus among animalists that the best way to avoid serious objections to their account is to adopt an ontology that denies the existence of brains, hands, tables, chairs, iced-tea, and (...) lemonade. The adoption of such an ontology reduces the justificatory force of commonsense, which is key in arguing that we are animals and that we persist as long as we are biologically alive. With this loss of justification comes the loss of a high level of confidence that Quinn-pre-dementia’s lethal advanced directive applies to Quinn-post-dementia, via identity. If we do not have a high level of confidence that Quinn-pre-dementia’s advanced directive applies to Quinn-post- dementia, then it is not enough (on its own) to let Quinn-post-dementia die. (shrink)

Animalism is the thesis that each human person is numerically identical to an animal. This work remains neutral on the truth of animalism. Instead of addressing the thesis, it considers the logical implications regarding a range of thought experiments in the personal identity literature, such as the brain transplant case, and argues that many prominent defenders of animalism have misapplied their own view. Based on what is generally accepted in the philosophy of biology, animalists ought to change their positions on (...) these case studies. Along with better matching our best theories of biology, this new perspective helps animalists avoid some of the most counter-intuitive implications of their position. (shrink)

My aim in this paper is to destabilise the brain-is-self thesis, something that is now regarded in some quarters as philosophical commonsense. My contention is that it is the epithelial body that enters into the formation of our sense of self and that largely bears the burden of personal identity as well as playing the key role in grounding our psychological ascriptions. Lacking any sensorimotor or social presence of its own, the brain by itself cannot "underlie" selfhood, but only as (...) part of the whole living human being. If the minded individual is embodied, this must mean more than being embrained. (shrink)

The paper takes off from the problem of finding a proper content for the relation of identity as it holds or fails to hold among ordinary things or substances. The necessary conditions of identity are familiar, the sufficient conditions less so. The search is for conditions at once better usable than the Leibnizian Identity of Indiscernibles (independently suspect) and strong enough to underwrite all the formal properties of the relation.It is contended that the key to this problem rests at the (...) level of metaphysics and epistemology alike with a sortalist position. Sortalism is the position which insists that, if the question is whether a and b are the same, it has to be asked what are they? Any sufficiently specific answer to that question will bring with it a principle of activity or functioning and a mode of behaviour characteristic of some particular kind of thing by reference to which questions of persistence or non-persistence through change can be adjudicated.These contentions are illustrated by reference to familiar examples such as the human zygote, the Ship of Theseus and Shoemaker's Brown-Brownson. The first example is hostage for a mass of unproblematical cases. The problems presented by the second and third sort of examples arise chiefly (it is claimed) from an incompleteness in our conceptions of the relevant sort—the what the thing in question is. That incompleteness need not prevent us from knowing perfectly well which thing we are referring to. In the concluding section, sortalism is defended against various accusations of anthropocentrism.The paper touches on the interpretation of Heraclitus, Leibniz's theory of clear indistinct ideas, the difficulties of David Lewis's ‘perdurantist’ or stroboscopic view of persistence, four-dimensionalism, and the relation of personal identity both to experiential memory and to the particular bodily physiognomy of a subject. At some points—as in connection with the so-called Only a and b rule—the paper corrects, supplements or extends certain theses or formulations proposed in the author's Sameness and Substance Renewed (2001).

Sydney Shoemaker leads today’s “neo-Lockean” liberation of persons from the conservative animalist charge of “neo-Aristotelians” such as Eric Olson, according to whom persons are biological entities and who challenge all neo-Lockean views on grounds that abstracting from strictly physical, or bodily, criteria plays fast and loose with our identities. There is a fundamental mistake on both sides: a false dichotomy between bodily continuity versus psychological continuity theories of personal identity. Neo-Lockeans, like everyone else today who relies on Locke’s analysis of (...) personal identity, including Derek Parfit, have either completely distorted or not understood Locke’s actual view. Shoemaker’s defense, which uses a “package deal” definition that relies on internal relations of synchronic and diachronic unity and employs the Ramsey–Lewis account to define personal identity, leaves far less room for psychological continuity views than for my own view, which, independently of its radical implications, is that (a) consciousness makes personal identity, and (b) in consciousness alone personal identity consists—which happens to be also Locke’s actual view. Moreover, the ubiquitous Fregean conception of borders and the so-called “ambiguity of is” collapse in the light of what Hintikka has called the “Frege trichotomy.” The Ramsey–Lewis account, due to the problematic way Shoemaker tries to bind the variables, makes it impossible for the neo-Lockean ala Shoemaker to fulfill the uniqueness clause required by all such Lewis style definitions; such attempts avoid circularity only at the expense of mistaking isomorphism with identity. Contrary to what virtually all philosophers writing on the topic assume, fission does not destroy personal identity. A proper analysis of public versus perspectival identification, derived using actual case studies from neuropsychiatry, provides the scientific, mathematical and logical frameworks for a new theory of self-reference, wherein “consciousness,” “self-consciousness,” and the “I,” can be precisely defined in terms of the subject and the subject-in-itself.

Four non-Cartesian conceptions of a person are considered. I argue tor one of these, a position called animalism. I reject the idea that a (human) person coincides with, but is numerically distinct from, a certain human animal. Coinciding physical beings would both be psychological subjects. I argue that such subjects could not engage in self-reference. Since self-reference (or the capacity tor self-reference) is a necessary condition for being a person, no physical subject coincident with another such subject can be a (...) person. I take all of this to support the view that we (human persons) are identical with human animals. (shrink)

Animalism—the view that the identity across time of individuals like us consists in the persistence of our animal organisms—does poorly at accounting for our identity-related practical concerns. The reason is straightforward: whereas our practical concerns seem to track the identity of psychological creatures—persons—animalism focuses on the identity of human organisms who are not essentially persons. This lack of fit between our practical concerns and animalism has been taken to reduce animalism’s plausibility (relative to psychological criteria of identity). In this paper, (...) I survey the three leading replies to this challenge, finding them either implausible or incomplete. I will then attempt to construct the only viable response, one that begins by admitting that our practical concerns actually do not consist in a monolithic set; rather, there are distinctly different types of practical concerns, and while some are clearly grounded on psychological relations, some are actually grounded on others, including animalistic and humanistic relations; furthermore, their actual connection to identity is tenuous at best. What these concerns are, how they divide up, and what they are grounded on in each instance—these are the issues it is my second aim in this paper to take up. (shrink)

Animalism is at once a bold metaphysical theory and a pedestrian biological observation. For according to animalists, human persons are organisms; we are members of a certain biological species. In this article, I introduce some heretofore unnoticed data concerning the interlocking interests of human persons and human organisms. I then show that the data support animalism. The result is a novel and powerful argument for animalism. Bold or pedestrian, animalism is true.

If we are physical things with parts, then accounts of what we are and accounts of when composition occurs have important implications for one another. Defenders of restricted composition tend to endorse a sparse ontology in taking an eliminativist stance toward composite objects that are not organisms, while claiming that we are organisms. However, these arguments do not entail that we are organisms, for they rely on the premise that we are organisms. Thus, sparsist reasoning need not be paired with (...) animalism, but could instead be paired with other accounts according to which we are composites. The embodied mind account—a version of the brain view—is one such account. Replacing the premise that we are organisms with the premise that we are embodied minds, in arguments that otherwise parallel those supporting animalist sparsism, yields an account according to which composite objects include thinkers, but perhaps nothing else. Since animalism has implausible implications about scenarios which are handled better by the embodied mind account, this approach is preferable to animalist sparsism. Furthermore, the role of mental features in sparsism makes embodied mind sparsism the more reasonable conclusion. Meanwhile, adopting sparsism allows the embodied mind account to dodge objections that may not be as easily avoided by it or other versions of the brain view if not paired with sparsism. These include objections about brains that are not persons, inorganic part replacement, and another form of part replacement that might seem to allow one to get a new brain. (shrink)

In his 1998 postscript to ‘The Possibility of Resurrection’ Peter van Inwagen argues that the scenario he describes by which God might resurrect a human organism, even though probably not true, is still conceivable and, consequently, ‘serves to establish a possibility’, namely, the metaphysical possibility of the resurrection of material beings. Van Inwagen, however, has also argued in favour of ‘modal scepticism’ [van Inwagen in, God, knowledge and mystery: essays in philosophical theology, Cornell University Press, Ithaca 1995b, pp. 11–12; van (...) Inwagen in, Philos Stud 92:67–84, 1998a]. That is, he thinks that we should limit all our claims about what is possible to ‘ordinary propositions about everyday matters’, 1998a). In this paper I argue that van Inwagen’s modal argument as found in ‘The Possibility of Resurrection’ is inconsistent with his modal scepticism as found in ‘Modal Epistemology’. In consequence, I argue that, given his modal scepticism, the task van Inwagen set himself in ‘The Possibility of Resurrection’ has not been achieved. (shrink)

Defendemos que a continuidade física garante a persistência pessoal no tempo. Determinamos, primeiro, os fundamentos teóricos e conceptuais do problema metafísico da identidade pessoal no tempo: apuramos a noção relevante de «identidade pessoal», a questão da persistência temporal simpliciter e aquilo em que consistem critérios identitários e princípios de individuação. Examinamos propriedades lógicas e formais do conceito de identidade: as leis da congruência, o princípio lógico da identidade, a reflexividade, simetria e transitividade, distinguimos as relações de identidade qualitativa e numérica (...) e problematizamos o Princípio dos Indiscerníveis. Diferenciamos as simple e complex views da taxinomia de critérios identitários, evidenciando a tese reducionista transversal às perspetivas complexas. Nas secções centrais, analisamos e discutimos os principais argumentos e objeções aduzidos aos critérios identitários dominantes, a saber, o critério lockeano da memória, critérios de dependência causal da conetividade e continuidade psicológicas, a partir do «paradoxo da fissão» cerebral, e seguidamente, o critério corpóreo ou físico, o animalismo, a perspetiva somática e o critério cerebral. Os critérios psicológicos não são considerados promissores. Desenvolvemos a hipótese de que a identidade pessoal consiste numa relação causal de continuidade física bruta original, demonstrando que a defesa de, pelo menos, um «fisicalismo mínimo» em relação à identidade mente-cérebro, assegura o seu reforço. Para tal, refinamos o critério corpóreo original, demonstrando que a defesa de, pelo menos, um «fisicalismo mínimo» em relação à identidade mente-cérebro, assegura o seu reforço. (shrink)

I argue that a form of animalism that does not include the belief that ‘human animal’ is a substance-sortal has a dialectical advantage over other versions of animalism. The main reason for this advantage is that Phase Animalism, the version of animalism described here, has the theoretical resources to provide convincing descriptions of the outcomes of scenarios problematic for other forms of animalism. Although Phase Animalism rejects the claim that ‘human animal’ is a substance-sortal, it is still appealing to those (...) who believe that our nature is continuous or of a similar kind to that of other physical entities.

Animalism is the view that human persons are human animals – biological organisms that belong to the species Homo sapiens. This paper concerns a family of modal objections to animalism based on the essentiality of personhood (persons and animals differ in their persistence conditions; psychological considerations are relevant for the persistence of persons, but not animals; persons, but not animals, are essentially psychological beings). Such arguments are typically used to support constitutionalism, animalism’s main neo-Lockean rival. The problem with such arguments (...) is that they wrongly assume that animalism is incompatible with our essentially being psychological beings. In this paper, I discuss a formulation of animalism, what I call psychologically-serious animalism, according to which human persons are essentially human animals and essentially persons. I show how the availability of this neglected formulation of animalism undermines objections based on the essentiality of personhood. (shrink)

Hylomorphism provides an attractive framework for addressing issues in philosophical anthropology. After describing a hylomorphic theory that dovetails with current work in philosophy of mind and in scientific disciplines such as biology and neuroscience, I discuss how this theory meshes with Christian eschatology, the doctrine of resurrection in particular.

Objects and Persons presents an original theory about what kinds of things exist. Trenton Merricks argues that there are no non-living inanimate macrophysical objects -- no statues or rocks or chairs or stars -- because they would have no causal role over and above the causal role of their microphysical parts. Humans do exist: we have non-redundant causal powers. Along the way, Merricks has interesting things to say about mental causation, free will, and various philosophical puzzles. Anyone working in metaphysics (...) will enjoy this lucid and provocative book. (shrink)

The topic of this book is material objects. Like most interesting concepts, the concept of a material object is one without precise boundaries.
