Nonphilosophers, if they think of philosophy at all, wonder why people work in metaphysics. After all, metaphysics, as Auden once said of poetry, makes nothing happen.1 Yet some very intelligent people are driven to spend their lives exploring metaphysical theses. Part of what motivates metaphysicians is the appeal of grizzly puzzles (like the paradox of the heap or the puzzle of the ship of Theseus). But the main reason to work in metaphysics, for me at least, is to understand the shared world that we all encounter and interact with. And the shared world that we all encounter includes us self-conscious beings and our experience. The world that we inhabit is unavoidably a temporal world: the signing of the Declaration of Independence is later than the Lisbon earthquake; the Cold War is in the past; your death is in the future. There is no getting away from time.

Nevertheless, I believe that, as it has been construed recently, the assumption is false. At the very least, it does not deserve the largely unquestioned status it enjoys, as I hope to show by a graduated series of thought experiments. I present the thought experiments as a series to expose a shared inadequacy in a variety of individualistic views, from type-type physicalism to the most sophisticated methodological solipsism; and I present them as graduated to suggest that having accepted the first relatively uncontroversial story, one has no principled place to demur later

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

The ontological argument in Anselm’s Proslogion II continues to generate a remarkable store of sophisticated commentary and criticism. However, in our opinion, much of this literature ignores or misrepresents the elegant simplicity of the original argument. The dialogue below seeks to restore that simplicity, with one important modification. Like the original, it retains the form of a reductio, which we think is essential to the argument’s great genius. However, it seeks to skirt the difficult question of whether 'exists' is a genuine predicate by appealing instead to a distinction between having only mediated causal powers and having unmediated causal powers. Pegasus has no unmediated causal powers, but he has mediated causal powers through the thoughts, depictions, and literature in which he figures. This distinction allows us to argue about the existence of God without begging any questions.

The first-person perspective is a challenge to naturalism. Naturalistic theories are relentlessly third-personal. The first-person perspective is, well, first-personal; it is the perspective from which one thinks of oneself as oneself* without the aid of any third-person name, description, demonstrative or other referential device. The exercise of the capacity to think of oneself in this first-personal way is the necessary condition of all our self-knowledge, indeed of all our self-consciousness. As important as the first-person perspective is, many philosophers have not appreciated the force of the data from the first-person perspective, and suppose that the first-person perspective presents no particular problems for the naturalizing philosopher. For example, Ned Block commented, “It is of course [phenomenal] consciousness rather than...self-consciousness that has seemed such a scientific mystery.” And David Chalmers says that self-consciousness is one of those psychological states that “pose no deep metaphysical enigmas.”

What is this thing called ‘Commonsense Psychology’? The first matter to settle is what the issue is here. By ‘commonsense psychology,’ I mean primarily the systems of describing, explaining and predicting human thought and action in terms of beliefs, desires, hopes, fears, expectations, intentions and other so-called propositional attitudes. Although commonsense psychology encompasses more than propositional attitudes--e.g., emotions, traits and abilities are also within its purview--belief-desire reasoning forms the core of commonsense psychology. Commonsense psychology is what we use to explain intentional action as ordinarily described--e.g., Jack went to the store because he wanted some ice cream. Commonsense psychology also is used to explain mental states--e.g., Jill feared that she would be late because she thought that the meeting began at 4:00. Commonsense psychology is the province of everyone; we all use it all the time

According to the Constitution View of persons, a human person is wholly constituted by (but not identical to) a human organism. This view does justice both to our similarities to other animals and to our uniqueness. As a proponent of the Constitution View, I defend the thesis that the coming-into-existence of a human person is not simply a matter of the coming-into-existence of an organism, even if that organism ultimately comes to constitute a person. Marshalling some support from developmental psychology, I give a broadly materialistic account of the coming-into-existence of a human person. I argue for the metaphysical superiority of the Constitution View to Biological Animalism, Thomistic Animalism, and other forms of Substance Dualism. I conclude by discussing the single implication of the Constitution View for thinking about abortion. Footnotesa Thanks to Gareth Matthews and Catherine E. Rudder for comments.

After an undergraduate degree with a major in mathematics, I turned to philosophy—in part because philosophy had all the interest of math (and logic) plus an indefinitely wide range of subject matter. I began philosophy at an intersection of metaphysics and philosophy of science. My dissertation, Ontological and Linguistic Aspects of Temporal Becoming, was on the philosophy of time. A convinced physicalist, I defended the idea that past, present and future (the A-series) are merely “mind-dependent.” I spent a year as a Mellon postdoctoral fellow at the University of Pittsburgh, working mainly with Adolf Grünbaum, who was very generous to me with his time. Other members of the philosophical community in Pittsburgh suggested that there was no philosophical interest in nowness; the word ‘now’ exhausted whatever there was of real interest concerning the status of the present. I therefore turned my attention from the status of the present (nowness) to the word ‘now’.

Through the ages, Christians have almost automatically been Mind-Body dualists. The Bible portrays us as spiritual beings, and one obvious way to be a spiritual being is to be (or to have) an immaterial soul. Since it is also evident that we have bodies, Christians naturally have thought of themselves as composite beings, made of two substances—a material body and a nonmaterial soul. Despite the historical weight of this position, I do not think that it is required either by Scripture or by Christian doctrine as it has developed through the ages. So, I want to argue that there is a Christian alternative to Mind-Body Dualism, and that the reasons in favor of the alternative outweigh those in favor of Mind-Body Dualism

I want to raise a question for which I have no definitive answer. The question is how to understand first-personal phenomena—phenomena that that can be discerned only from a first-personal point of view. The question stems from reflection on two claims: First, the claim of scientific naturalism that all phenomena can be described and explained by science; and second, the claim of science that everything within its purview is intersubjectively accessible, and hence that all science is constructed exclusively form the third-personal point of view. Using these two claims as premises, we can construct a simple valid argument, which I’ll label ‘The Master Argument:’.

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.

On September 11, 2001, as everyone knows, the towers of the World Trade Center in New York were attacked. I want to discuss this event in order to motivate a nonreductionist view of the extensions of everyday concepts. Next, I shall set out, and begin to defend, the particular view of nonreductionism that I favor—the Constitution View. Then, I shall consider two venerable metaphysical issues (the nature of vagueness and the mind-independent/mind- dependent distinction) in light of the Constitution View. If the Constitution View is correct, then everyday concepts are a good guide to reality. My aim is to offer a metaphysical theory that acknowledges the genuine reality of what our everyday concepts (as well as our scientific concepts) are concepts of.

The Representational Theory of the Mind (RTM) has been forcefully and subtly developed by Jerry A. Fodor. According to the RTM, psychological states that explain behavior involve tokenings of mental representations. Since the RTM is distinguished from other approaches by its appeal to the meaning or "content" of mental representations, a question immediately arises: by virtue of what does a mental representation express or represent an environmental property like coto or shoe? This question asks for a general account of the semantics of mental representation. Fodor places two conditions on the requisite theory: it must be physi calistic (that is, it must be couched in nonsemantic and nonintentional terms, free of expressions like "refers to" or "denotes" or "means that"), and it must be atomistic (that is, it must allow that the thinker can have a single intentional state without having any others). What is wanted, then, is a reductive theory that "naturalizes" content by specifying sufficient conditions, in physicalistic and atomistic terms, for a mental symbol to represent or express a certain property

Arguments about temporal becoming often get nowhere. One reason for the impasse lies in the fact that the issue has been formulated as a choice between science on the one hand and common sense (or ordinary language) on the other as the primary source of ontological commitment.' Often' proponents of attributing temporal becoming to the physical universe look to everyday temporal concepts, find them infested with notions involving temporal becoming and conclude that becoming is a basic feature of the physical world. Their opponents may look to physical science, find no reference to temporal becoming and conclude that becoming is not part of the extramental universe.2 Thus construed, the issue of temporal becoming is not directly amenable to argument. This stalemate will be broken, however, if I accomplish my aim: to (re)formulate the question of temporal becoming so that it is subject to adjudication; to show how objections to the thesis of the mind-dependence of becoming can fruitfully be seen (and in a sense unified) as attacks on a single argument for the thesis, an argument from physics; and to defend the con'elusion of the argument from physics from heretofore unanswered objections. The question of the status of temporal becoming is the question of the status of past, present and future.' Events which are at one time in the future, are said to become present and subsequently to recede into the past. Since past and future can be defined as 'earlier than now' and 'later than..
