Lynne Rudder Baker and many others think that paradigmatic instances of one object constituting another — a piece of marble constituting a statue, or an aggregate of particles constituting a living body — involve two distinct (i.e., not numerically identical) objects in the same place at the same time.1 Some who say this believe in the doctrine of temporal parts2; but others, like Baker, reject this doctrine.3 Such philosophers, whom one might call “coincidentalists”, cannot say that these objects manage to share space in virtue of sharing a temporal part confined to just that place and time. But what can or should coincidentalists say about the nature of constitution?

We run into instances of material constitution everywhere we turn. Material constitution is the relation that obtains between an octagonal piece of metal and a Stop sign, between strands of DNA molecules and genes, between pieces of paper and dollar bills, between stones and monuments, between lumps of clay and statues, between human persons and their bodies—the list is endless. Although there has been a great deal of controversy recently about the nature of material constitution, I want to enter the fray by setting out and defending an explicit definition of what it is for an object x to constitute an object y at time t.

The nature of persons is a perennial topic of debate in philosophy, currently enjoying something of a revival. In this volume for the first time metaphysical debates about the nature of human persons are brought together with related debates in philosophy of religion and theology. Fifteen specially written essays explore idealist, dualist, and materialist views of persons, discuss specifically Christian conceptions of the value of embodiment, and address four central topics in philosophical theology: incarnation, resurrection, original sin, and the trinity.

In her recent book Persons and Bodies1, Lynne Rudder Baker has defended what she calls the constitution view of persons. On this view, persons are constituted by their bodies, where “constitution” is a ubiquitous, general metaphysical relation distinct from more familiar relations, such as identity and part-whole composition.

We human persons have an abiding interest in understanding what kind of beings we are. However, it is not obvious how to attain such an understanding. Traditional analytic metaphysicians start with a priori accounts of the most general, abstract features of the world— e.g., accounts of properties and particulars—features that, they claim, in no way depend upon us or our activity.1 Such accounts are formulated in abstraction from what is already known about persons and other things, and are used as constraints on metaphysical investigation of everything else. So, if we accept traditional metaphysics, we should be prepared to yield to abstruse pronouncements—either by giving up our most secure beliefs about the world that we encounter or by abandoning our conception of what those beliefs are really about.

The question—Are Persons More than Social Objects?—is an important one, and my answer is somewhat complicated. What I shall talk about here is the way in which persons are natural objects, but I do not want to deny that we are also social objects. I believe that to be a person in the way that I shall describe—as a natural object—is a necessary condition for various enterprises that may be thought of as the social construction of persons. For example, one could not construct a self­narrative that makes sense of one’s life as a whole unless one had the formal ontological property of personhood that I’ll discuss.

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.

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.

In the large recent literature on the nature of human persons, persons are usually studied in isolation from the world in which they live. What persons are most fundamentally, philosophers say, are human animals, or brains, or perhaps souls—without any consideration of the social and physical environments without which persons would not exist. I confess that I, too, have been guilty at times of focusing narrowly on persons without regard to the world in which they live.

In the large recent literature on the nature of human persons, persons are usually studied in isolation from the world in which they live. What persons are most fundamentally, philosophers say, are human animals, or brains, or perhaps souls -- without any consideration of the social and physical environments without which persons would not exist. In this article, I want to compensate for such overly narrow focus. Instead of beginning with the nature of persons cut off from any environment, I shall begin with metaphysical consideration of the world of which persons are a part. I shall then briefly describe my view of persons, according to which persons are material objects like other concrete things in the world, but are unique in their first-person perspectives. Finally, I shall consider some of the special relations that persons, and only persons, have to other things in the world.
