I critically discuss both the particular doctrinal and general meta-philosophical or methodological tenets of Mark Johnston's paper "Human Beings", attending to several weaknesses in his argument. One of the most important amongst them is an apparent reliance on a substitution of identicals within an intensional context as he argues that continuity of functioning brain is essential to the persistence of "Human Beings" as allegedly singled out by his methodology; another equally important is a simple lacuna in place of an argument (...) that candidate entities for re-identification by means we take for granted in the case of persons cannot be what I call "mentalistically" individuated.

RésuméLes philosophes appartenant à la tradition lockienne considèrent qu'en tant que personnes ou sujets de pensée et d'expérience, nous sommes distincts de nos organismes humains. Cela conduirait, selon des théoriciens qui veulent plutôt nous identifier à ces organismes, à un dédoublement paradoxal des sujets en question. Les objectifs principaux de cet article sont, premièrement, de soutenir à l'encontre de cet argument que la séparabilité des personnes par rapport à leurs organismes peut être comprise d'une manière non paradoxale; et deuxièmement, de (...) souligner qu'il ne faut par inférer de cette séparabilité que nous soyons identiques aux personnes plutôt qu'aux organismes humains.

ABSTRACT: There are some problems with Lynne Baker’s constitution account of personal identity that become evident when we consider brain transplant thought experiments and two kinds of rare cases of conjoined twins — the first appears to be one organism but two persons and the second seems to involve two organisms associated with one person. To handle the problems arising from brain transplants, the constitution theorist must admit an additional level of constitution between the organism and the person. To resolve (...) the problems posed by the two kinds of conjoined twins, the constitution theorist must accept that constitution is not always a one-to-one relationship. RESUME: La théorie constitutionnelle de l’identité personnelle de Lynne Baker soulève certains problèmes qui deviennent évidents lorsque l’on considère des expériences de pensée sur des transplantations de cerveaux et deux genres de cas rares de jumeaux conjoints — du premier cas paraît s’ensuivre qu’il y a deux personnes pour un seul organisme alors que du deuxième découle qu’une seule personne existe dans deux organismes. Afin d’expliquer les problèmes qui surviennent avec les transplantations de cerveaux, le théoricien de la constitution doit admettre un niveau de constitution intermédiaire entre l’organisme et la personne. Pour résoudre les problèmes que posent les cas de jumeaux conjoints, le théoricien de la constitution doit accepter que la relation de constitution ne se réalise pas toujours entre deux termes.

A number of claims are closely connected with, though logically distinct from, animalism. One is that organisms cease to exist when they die. Two others concern the relation of the brain, or the brainstem, to animal life. One of these holds that the brainstem is necessary for life—more precisely, that (say) my cat's brainstem is necessary for my cat's life to continue. The other is that it is sufficient for life—more precisely, that so long as (say) my cat's brainstem continues (...) to function, so too does my cat. I argue against these claims. (shrink)

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of psychological characteristics is (...) required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

Volumes I and II provided a completely new translation of the philosophical works of Descartes, based on the best available Latin and French texts. Volume III contains 207 of Descartes' letters, over half of which have previously not been translated into English. It incorporates, in its entirety, Anthony Kenny's celebrated translation of selected philosophical letters, first published in 1970. In conjunction with Volumes I and II it is designed to meet the widespread demand for a comprehensive, authoritative and accurate edition (...) of Descartes' philosophical writings in clear and readable modern English.

What does it mean to say that this person at this time is 'the same' as that person at an earlier time? If the brain is damaged or the memory lost, how far does a person's identity continue? In this book two eminent philosophers develop very different approaches to the problem.

Lockean accounts of personal identity face a problem of too many thinkers arising from their denial that we are identical to our animals and the assumption that our animals can think. Sydney Shoemaker has responded to this problem by arguing that it is a consequence of functionalism that only things with psychological persistence conditions can have mental properties, and thus that animals cannot think. I discuss Shoemaker’s argument and demonstrate two ways in which it fails. Functionalism does not rid the (...) Lockean of the problem of too many thinkers. (shrink)

The view that we are human animals, " animalism ", is deeply unpopular. This paper explains what that claim says and why it is so contentious. It then argues that those who deny it face an awkward choice. They must either deny that there are any human animals, deny that human animals can think, or deny that we are the thinking things located where we are.

What are you and I essentially? When do you and I come into and go out of existence? A common response is that we are essentially organisms, that is, we come into existence as organisms and go out of existence when we cease to be organisms. Jeff McMahan has put forward two arguments against the Organism View: the case of dicephalus and a special case of hemispheric commissurotomy. In this paper, I defend the Organism View against these two cases. Because (...) it is possible to devise more McMahanian-type cases, I also provide a more general solution to these kinds of cases. (shrink)

One increasingly popular approach to personal identity is called ‘animalism.’ Unfortunately, it is unclear just what the doctrine says. In this paper, I criticise several different ways of stating animalism, and put forward one formulation that I find more promising.

The rare condition known as dicephalus occurs when (prior to implantation) a zygote fails to divide completely, resulting in twins who are conjoined below the neck. Human dicephalic twins look like a two-headed person, with each brain supporting a distinct mental life. Jeff McMahan has recently argued that, because they instance two of us but only one animal, dicephalic twins provide a counterexample to the animalist's claim that each of us is identical with a human animal. To the contrary, I (...) argue that in cases of dicephalus it is obvious neither that there is one animal nor that there are two of us. Consequently, the animalist criterion does not straightforwardly apply to cases of dicephalus. I defend an account of dicephalus that is both sensitive to the complexity of twinning phenomena and not inconsistent with animalism. In my view, dicephalic twins are a borderline case of the concept HUMAN ANIMAL. I conclude with some speculative remarks concerning the normative import (if any) of my claim that dicephalic twins are a borderline case. (shrink)

In ‘Animalism versus Lockeanism: a Current Controversy’, The Philosophical Quarterly, 48 (1998), pp. 302–18, Harold Noonan examined the relation between animalist and neo‐Lockean theories of personal identity. As well as presenting arguments intended to support a modest compatibilism of animalism and neo‐Lockeanism, he advanced a new proposal about the relation between persons and human beings which was intended to evade the principal animalist objections to neo‐Lockean theories. I argue both that the arguments for compatibilism are without force, and that Noonan’s (...) new neo‐Lockean proposal is inadequate. (shrink)

My purpose is to explore the possible lines of reply available to a defender of the neo‐Lockean position on personal identity in response to the recently popular ‘animalist’ objection. I compare the animalist objection with an objection made to Locke by Bishop Butler, Thomas Reid and, in our own day, Sydney Shoemaker. I argue that the only possible response available to a defender of Locke against the Butler–Reid–Shoemaker objection is to reject Locke's official definition of a person as a thinking, (...) intelligent thing and replace it with the concept of the self– the object of self‐reference – and that this response is equally obligatory for the neo‐Lockean in replying to the animalist. I explore other possibilities, including the position that there is no sense in talking about personal identity at all. (shrink)

The apparent fact that each of us coincides with a thinking animal looks like a strong argument for our being animals (animalism). Some critics, however, claim that this sort of reasoning actually undermines animalism. According to them, the apparent fact that each human animal coincides with a thinking body that is not an animal is an equally strong argument for our not being animals. I argue that the critics' case fails for reasons that do not affect the case for animalism.

One reason why the Biological Approach to personal identity is attractive is that it doesn’t make its advocates deny that they were each once a mindless fetus.[i] According to the Biological Approach, we are essentially organisms and exist as long as certain life processes continue. Since the Psychological Account of personal identity posits some mental traits as essential to our persistence, not only does it follow that we could not survive in a permanently vegetative state or irreversible coma, but it (...) would appear that none of us was ever a mindless fetus. But what happens to the organism that was a mindless fetus when the _person_ arrives on the scene?[ii] Can the acquisition of thought destroy an organism? That would certainly be news to biologists. Does one organism cease to exist with the emergence of thought and another organism, one identical to the person, take its place? (Burke,1994) That doesn’t seem much more plausible than the previous move. Should identity and Leibniz. (shrink)

Defenders of the Psychological Approach to Personal Identity (PAPI) insist that the possession of some kind of mind is essential to us. We are essentially thinking beings, not living creatures. We would cease to exist if our capacity for thought was irreversibly lost due to a coma or permanent vegetative state. However, the onset of such conditions would not mean the death of an organism. It would survive in a mindless state. But this would appear to mean that before the (...) loss of cognition and the destruction of the person, the organism and the person were spatially coincident entities – two beings composed of the same matter at the same time and place. Perhaps the most problematic aspect of positing spatially coincident material entities is that it would seem to result in there being one too many thinkers. Since the person can obviously think, the organism should also have such a capacity as a result of possessing the same brain as well as every other atom of the person. This means that there now exist two thinking beings under the reader’s clothes! (shrink)

What is the self? And how does it relate to the body? In the second edition of Personal Identity, Harold Noonan presents the major historical theories of personal identity, particularly those of Locke, Leibniz, Butler, Reid and Hume. Noonan goes on to give a careful analysis of what the problem of personal identity is, and its place in the context of more general puzzles about identity. He then moves on to consider the main issues and arguments which are the subject (...) of current debate, including the work of Bernard Williams and Derek Parfit, and makes new and challenging interpretations of them. This new edition contains additional material assessing the biological approach which has become increasingly popular in recent years, and extends the treatment of indeterminate identity to take account of the epistemic view of vagueness. This book covers the problem of personal identity from its origin in Locke's work to the most recent debates in the philosophical literature, and will be invaluablereading for any student of the topic.

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

A key to modern studies of 18th century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity and morality. This abridged edition has an introduction which explain's Hume's thought and places it in the context of its times.

Hud Hudson presents an innovative view of the metaphysics of human persons according to which human persons are material objects but not human organisms. In developing his account, he formulates and defends a unique collection of positions on parthood, persistence, vagueness, composition, identity, and various puzzles of material constitution. The author also applies his materialist metaphysics to issues in ethics and in the philosophy of religion. He examines the implications for ethics of his metaphysical views for standard arguments addressing the (...) moral permissibility of our treatment of human persons and their parts, fetuses and infants, the irreversibly comatose, and corpses. He argues that his metaphysics provides the best foundation in the philosophy of religion for the Christian doctrine of the resurrection of the body. Hudson addresses a broad range of metaphysical issues, but among his most strikingly original contributions are his defense of the "Partist" view and his argument for the compatibility of Christianity with a materialistic theory of human persons.

I respond to criticisms by David Mackie of my previous paper on animalism and Lockeanism. I argue that the ‘transplant intuition’, that a person goes where his brain (or cerebrum) goes, is compatible both with animalism and Lockeanism. I give three arguments for this conclusion, two of them developing lines of thought in Parfit's work. However, I accept that animalism and Lockeanism are incompatible, and I go on to consider the difficulties for Lockeanism that this raises. The principal difficulty, concerning (...) the reference of ‘I’, can be met by distinguishing the thinker of an ‘I’‐thought from the reference of an ‘I’‐thought. The reference is always the person thinking the thought, but when the thought is simultaneously that of an animal coincident but non‐identical with that person, there is not a unique thinker. Mackie's criticisms of this view are ineffective. (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)

Both advocates and opponents of the animalist view that we are fundamentally biological organisms have typically assumed that animalism is incompatible with intuitive verdicts about cerebrum isolation and transplantation. It is argued here that this assumption is a mistake. Animalism, developed in a natural way, in fact strongly supports these intuitive verdicts. The availability of this attractive resolution of a central puzzle in the personal identity debate has been obscured by a range of factors, including the prevalence in contemporary metaphysics (...) of a certain conception of the nature of organisms. I end by explaining how the animalist can use intuitive verdicts, usually thought to present a difficulty for the view, as positive evidence for claims about the persistence conditions of the relevant kind of organism. (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.

‘Soul’, ‘self’, ‘substance’ and ‘person’ are just four of the terms often used to refer to the human individual. Cutting across metaphysics, ethics, and religion the nature of personal identity is a fundamental and long-standing puzzle in philosophy. Personal Identity and Applied Ethics introduces and examines different conceptions of the self, our nature, and personal identity and considers the implications of these for applied ethics. A key feature of the book is that it considers a range of different approaches to (...) personal identity; philosophical, religious, and cross-cultural, including perspectives from non-Western traditions. Within this comparative framework, Andrea Sauchelli examines the following topics: -Early views of the soul in Plato, Christianity, and Descartes -The Buddhist ‘no-self’ views and the self as a fiction -Confucian ideas of our nature and the importance of self-cultivation as constitutive of the self -Locke’s theory of personal identity as continuity of consciousness and memory and objections to Locke’s argument by Butler and Reid as well as contemporary critics -The theory of ‘animalism’ and arguments concerning embodied concepts of personal identity -Practical and narrative theories of personal identity and moral agency -Personal identity and issues in applied ethics, including abortion, organ transplantation, and the idea of life after death -Implications of life-extending technologies for personal identity. Throughout the book Sauchelli also considers the views of important recent philosophers of personal identity such as Sydney Shoemaker, Bernard Williams, Derek Parfit, Marya Schechtman, and Christine Korsgaard, placing these in helpful historical context. Chapter summaries, a glossary of key terms, and suggestions for further reading make this a refreshing, approachable introduction to personal identity and applied ethics. It is an ideal text for courses on personal identity that consider both Western and non-Western approaches and that apply theories of personal identity to ethical problems. It will also be of interest to those in related subjects such as religious studies and history of ideas. (shrink)

In this innovative study of the relationship between persons and their bodies, E. J. Lowe demonstrates the inadequacy of physicalism, even in its mildest, non-reductionist guises, as a basis for a scientifically and philosophically acceptable account of human beings as subjects of experience, thought and action. He defends a substantival theory of the self as an enduring and irreducible entity - a theory which is unashamedly committed to a distinctly non-Cartesian dualism of self and body. Taking up the physicalist challenge (...) to any robust form of psychophysical interactionism, he shows how an attribution of independent causal powers to the mental states of human subjects is perfectly consistent with a thoroughly naturalistic world view. He concludes his study by examining in detail the role which conscious mental states play in the human subject's exercise of its most central capacities for perception, action, thought and self-knowledge.

John Locke is the greatest English philosopher. _An Essay Concerning Human Understanding_, one of the most influential books in the history of thought, is his greatest work. In this study the historical meaning and philosophical significance of Locke's _Essay_ are investigated more comprehensively than ever before. _Locke_ was originally published in two volumes, _Epistemology_ and _Ontology_. This paperback edition has within its covers the full text of both volumes.

A major objection to the view that the relation of persons to human animals is coincidence rather than identity is that on this view the human animal will share the coincident person's physical properties, and so should (contrary to the view) share its mental properties. But while the same physical predicates are true of the person and the human animal, the difference in the persistence conditions of these entities implies that there will be a difference in the properties ascribed by (...) these predicates, with the result that the physical properties that determine the person's mental states will belong to the person and not to the human animal.

Johnston presents an argument for a form of immortality that divests the notion of any supernatural elements. The book is packed with illuminating philosophical reflection on the question of what we are, and what it is for us to persist over time.

What is a human person, and what is the relation between a person and his or her body? In her third book on the philosophy of mind, Lynne Rudder Baker investigates what she terms the person/body problem and offers a detailed account of the relation between human persons and their bodies. Baker's argument is based on the 'Constitution View' of persons and bodies, which aims to show what distinguishes persons from all other beings and to show how we can be (...) fully material beings without being identical to our bodies. The Constitution View yields answers to the questions 'What am I most fundamentally?', 'What is a person?', and 'What is the relation between human persons and their bodies'? Baker argues that the complex mental property of first-person perspective enables one to conceive of one's body and mental states as one's own. (shrink)

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a form (...) of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

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.
