Much of the debate about identity in recent decades has been about personal identity, and specifically about personal identity over time, but identity generally, and the identity of things of other kinds, have also attracted attention. Various interrelated problems have been at the centre of discussion, but it is fair to say that recent work has focussed particularly on the following areas: the notion of a criterion of identity; the correct analysis of identity over time, and, in particular, the disagreement (...) between advocates of perdurance and advocates of endurance as analyses of identity over time; the notion of identity across possible worlds and the question of its relevance to the correct analysis of de re modal discourse; the notion of contingent identity; the question of whether the identity relation is, or is similar to, the composition relation; and the notion of vague identity. A radical position, advocated by Peter Geach, is that these debates, as usually conducted, are void for lack of a subject matter: the notion of absolute identity they presuppose has no application; there is only relative identity. Another increasingly popular view is the one advocated by Lewis: although the debates make sense they cannot genuinely be debates about identity, since there are no philosophical problems about identity. Identity is an utterly unproblematic notion. What there are, are genuine problems which can be stated using the language of identity. But since these can be restated without the language of identity they are not problems about identity. (For example, it is a puzzle, an aspect of the so-called “problem of personal identity”, whether the same person can have different bodies at different times. But this is just the puzzle whether a person can have different bodies at different times. So since it can be stated without the language of personal “identity”, it is not a problem about identity, but about personhood.) This article provides an overview of the topics indicated above, some assessment of the debates and suggestions for further reading. (shrink)

relation between, say, a lump of clay and a statue that it makes up, or between a red and white piece of metal and a stop sign, or between a person and her body? Assuming that there is a single relation between members of each of these pairs, is the relation “strict” identity, “contingent” identity or something else?1 Although this question has generated substantial controversy recently,2 I believe that there is philo- sophical gain to be had from thinking through the (...) issues from scratch. Many of the charges and countercharges are based on the following dichotomy: For any x and y that are related as the lump of clay is to the statue that it makes up, either x is identical to y, or x and y are separate entities, independent of each other. By giving up this dichotomy, we will be able to begin to make sense, I hope, of an intermediate unity relation that holds promise for solving a raft of philosophical problems, including the problem of how persons are related to their bodies.3 And if I am correct, then this relation—constitution without identity—is ubiquitous and interesting in its own right, apart from the light that it sheds on human persons.

Throughout his illustrious career, Roderick Chisholm was concerned with the nature of persons. On his view, persons are what he called ‘entia per se.’ They exist per se, in their own right. I too have developed an account of persons—I call it the ‘Constitution View’—an account that is different in important ways from Chisholm’s. Here, however, I want to focus on a thesis that Chisholm and I agree on: that persons have ontological significance in virtue of being persons. Although I’ll (...) make the notion of ontological significance more precise later, the rough idea is that Fs (persons, or whatever) have ontological significance just in case a new F is a new thing and not just a change in some already-existing thing.

A bronze statue is a lump of bronze – or so it might appear. But appearances are not always to be trusted, and this one is notoriously problematic. To see why, imagine a bronze statue (perhaps a statue of David) and ask yourself: Which lump of bronze is the statue? Presumably, it is the lump that makes up the statue (or, as we say, the lump that constitutes the statue). After all, why should the statue be any other lump of (...) bronze? But if that is right, if the statue is the lump of bronze that constitutes it, then why can the lump of bronze survive being melted down whereas the statue it constitutes cannot? It seems that in fact the bronze statue is not the lump of bronze that constitutes it, since the statue and the lump of bronze have different persistence conditions. But then is it some other lump of bronze? Is it a lump of bronze at all? These questions are troubling; they appear to have no easy answers. (shrink)

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

In “Was I Ever a Fetus?” I argued that, since each of us was once an unthinking fetus, psychological continuity cannot be necessary for us to persist through time. Baker claims that the argument is invalid, and that both the premise and the conclusion are false. I attempt to defend argument, premise, and conclusion against her objections.

This is an investigation of Aristotle's conception of accidental compounds (or "kooky objects," as Gareth Matthews has called them)—entities such as the pale man and the musical man. I begin with Matthews's pioneering work into kooky objects, and argue that they are not so far removed from our ordinary thinking as is commonly supposed. I go on to assess their utility in solving some familiar puzzles involving substitutivity in epistemic contexts, and compare the kooky object approach to more modern approaches (...) involving the notion of referential opacity. I conclude by proposing that Aristotle provides an implicit role for kooky objects in such metaphysical contexts as the Categories and Metaphysics. (shrink)

Beginning with Aristotle, philosophers have taken artifacts to be ontologically deficient. This paper proposes a theory of artifacts, according to which artifacts are ontologically on a par with other material objects. I formulate a nonreductive theory that regards artifacts as constituted by - but not identical to - aggregates of particles. After setting out the theory, I rebut a number of arguments that disparage the ontological status of artifacts.

Chisholm held that persons are essentially persons. The Constitution View affords a non-Chisholmian way to defend the thesis that persons are essentially persons. The Constitution View shows how persons are constituted by---but not identical to---human animals. On the Constitution View, being a person determines a person’s persistence conditions. On the Animalist View, being an animal determines a person’s persistence conditions.Things of kind K have ontological significance if their persistence conditions are determined by their being members of K. On Chisholm’s view, (...) persons have ontological significance, but animals do not. On Animalism, animals have ontological significance, but persons do not. After explaining the notion of ontological significance, this article argues that persons do have ontological significance, and hence that Animalism is not true. (shrink)

Theories of the human person differ greatly in their ability to underwrite a metaphysics of resurrection. This paper compares and contrasts a number of such views in light of the Christian doctrine of resurrection. In a Christian framework, resurrection requires that the same person who exists on earth also exists in an afterlife, that a postmortem person be embodied, and that the existence of a postmortem person is brought about by a miracle. According to my view of persons (the Constitution (...) View), a human person is constituted by—but not identical to—a human organism. A person has a first-person perspective essentially, and an organism has interrelated biological functions essentially. I shall argue for the superiority the Constitution View as a metaphysical basis for resurrection. (shrink)

Many Christians assume that there are only two possibilities for what a human person is: either Animalism (the view that we are fundamentally animals) or Immaterialism (the view that we are fundamentally immaterial souls). I set out a third possibility: the Constitution View (the view that we are material beings, constituted by bodies but not identical to the bodies that now constitute us.) After setting out and briefly defending the Constitution View, I apply it to the doctrine of resurrection. I (...) conclude by giving reasons for Christians to prefer the Constitution View of human persons to both Animalism and Immaterialism. (shrink)

Lynne Rudder Baker presents and defends a unique account of the material world: the Constitution View. In contrast to leading metaphysical views that take everyday things to be either non-existent or reducible to micro-objects, the Constitution View construes familiar things as irreducible parts of reality. Although they are ultimately constituted by microphysical particles, everyday objects are neither identical to, nor reducible to, the aggregates of microphysical particles that constitute them. The result is genuine ontological diversity: people, bacteria, donkeys, mountains and (...) microscopes are fundamentally different kinds of things - all constituted by, but not identical to, aggregates of particles. Baker supports her account with discussions of non-reductive causation, vagueness, mereology, artefacts, three-dimensionalism, ontological novelty, ontological levels and emergence. The upshot is a unified ontological theory of the entire material world that irreducibly contains people, as well as non-human living things and inanimate objects. (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)
