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)

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)

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)

On the most popular account of material constitution, it is common for a material object to coincide precisely with one or more other material objects, ones that are composed of just the same matter but differ from it in sort. I argue that there is nothing that could ground the alleged difference in sort and that the account must be rejected.

The book also includes a chronological table of significant events, select bibliography, succinct explanatory notes, and an index--all of which supply ...

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.

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.

There is a well-known argument from Leibniz's Law for the view that coincident material things may be distinct. For given that they differ in their properties, then how can they be the same? However, many philosophers have suggested that this apparent difference in properties is the product of a linguistic illusion; there is just one thing out there, but different sorts or guises under which it may be described. I attempt to show that this ‘opacity’ defence has intolerable consequences for (...) the functioning of our language and that the original argument should therefore be allowed to stand. (shrink)

It is often said that the same particles can simultaneously make up two or more material objects that differ in kind and in their mental, biological, and other qualitative properties. Others wonder how objects made of the same parts in the same arrangement and surroundings could differ in these ways. I clarify this worry and show that attempts to dismiss or solve it miss its point. At most one can argue that it is a problem we can live with.

The Standard View of personal identity says that someone who exists now can exist at another time only if there is continuity of her mental contents or capacities. But no person is psychologically continuous with a fetus, for a fetus, at least early in its career, has no mental features at all. So the Standard View entails that no person was ever a fetus--contrary to the popular assumption that an unthinking fetus is a potential person. It is also mysterious what (...) does ordinarily happen to a human fetus, if it does not come to be a person. Although an extremely complex variant of the Standard View may allow one to persist without psychological continuity before one becomes a person but not afterwards, a far simpler solution is to accept a radically non-psychological account of our identity.

The Termination Thesis (or “TT”) is the view that people go out of existence when they die. Lots of philosophers seem to believe it. Epicurus, for example, apparently makes use of TT in his efforts to show that it is irrational to fear death. He says, “as long as we exist, death is not with us; but when death comes, then we do not exist.”1 Lucretius says pretty much the same thing, but in many more words and more poetically: “Death (...) therefore to us is nothing, concerns us not a jot, since the nature of the mind is proved to be mortal; . . . when we shall be no more, when there shall have been a separation of body and soul, out of both of which we are each formed into a single being, to us, you may be sure, who then shall be no more, nothing whatever can happen to excite sensation.”. (shrink)

A lot of people believe that distinct objects can occupy precisely the same place for the entire time during which they exist. Such people have to provide an answer to the 'grounding problem' – they have to explain how such things, alike in so many ways, nonetheless manage to fall under different sortals, or have different modal properties. I argue in detail that they cannot say that there is anything in virtue of which spatio-temporally coincident things have those properties. However, (...) I also argue that this may not be as bad as it looks, and that there is a way to make sense of the claim that such properties are primitive. (shrink)

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous thought-experiments dealing (...) with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

Sydney Shoemaker argues that the functionalist theory of mind entails a psychological-continuity view of personal identity, as well as providing a defense of that view against a crucial objection. I show that his view has surprising consequences, e.g. that no organism could have mental properties and that a thing's mental properties fail to supervene even weakly on its microstructure and surroundings. I then argue that the view founders on "fission" cases and rules out our being material things. Functionalism tells us (...) little if anything about personal identity. (shrink)

Personal identity deals with questions about ourselves qua people (or persons). Many of these questions are familiar ones that occur to everyone at some time: What am I? When did I begin? What will happen to me when I die? Discussions of personal identity go right back to the origins of Western philosophy, and most major figures have had something to say about it. (There is also a rich literature on personal identity in Eastern philosophy, which I am not competent (...) to discuss. Collins 1982 is a good source.). (shrink)

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 paper is concerned with how neo-Lockean accounts of personal identity should respond to the challenge of animalist accounts. Neo-Lockean accounts that hold that persons can change bodies via brain transplants or cerebrum transplants are committed to the prima facie counterintuitive denial that a person is an (biologically individuated) animal. This counterintuitiveness can be defused by holding that a person is biological animal (on neo-Lockean views) if the “is” is the “is” of constitution rather than the “is” of identity, and (...) that a person is identical with an animal in a sense of “animal” different from that which requires the persistence conditions of animals to be biological. Another challenge is the “too many minds problem”: if persons and their coincident biological animals share the same physical properties, and mental properties supervene on physical properties, the biological animal will share the mental properties of the person, and so should itself be a person. The response to this invokes a distinction between “thin” properties, which are shared by coincident entities, and “thick” properties which are not so shared. Mental properties, and their physical realizers, are thick, not thin, so are not properties persons share with their bodies or biological animals. The paper rebuts the objection that neo-Lockean accounts cannot explain how persons can have physical properties. To meet a further problem it is argued that the biological properties of persons and those of biological animals are different because of differences in their causal profiles. (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.

Eric Olsen argues from the fact that we once existed as fetal individuals to the conclusion that the Standard View of personal identity is mistaken. I shall establish that a similar argument focusing upon dead people opposes Olson’s favored Biological View of personal identity.

What is the relation between a clay statue andthe lump of clay from which it is made? According to the defender of the standardaccount, the statue and the lump are distinct,enduring objects that share the same spatiallocation whenever they both exist. Suchobjects also seem to share the samemicrophysical structure whenever they bothexist. This leads to the standard objection tothe standard account: if the statue and thelump of clay have the same microphysicalstructure whenever they both exist, how canthey differ in their (...) de re temporalproperties, de re modal properties and soon? In this paper I develop amereological answer to this question – thestatue and the lump differ with respect totheir parts and this explains theirdifference with respect to de re temporalproperties, de re modal properties andthe like.

[Sydney Shoemaker] 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. /// [Galen Strawson] What are the grounds of self-consciousness? I consider 29 proposals and reject 22, including a number of proposals that experience of body (or bodies) is necessary for self-consciousness. A popular strategy in debates of this sort is to argue that one cannot be said to have some concept C (e.g. the concept ONESELF, necessary for self-consciousness) unless one has a need or a use for C given the character of one's experience considered independently of the character that it has given that one possesses C. I suggest that such arguments are invalid. (shrink)
