This piece is a contribution to a book symposium on Fabrice Correia and Sven Rosenkranz's _Nothing to Come: A Defense of the Growing Block Theory of Time_. I start by considering one of the main objections that has been raised against the Growing Block Theory, namely, the Epistemic Objection, together with Correia and Rosenkranz's response to that objection. This leads to a question about whether Correia and Rosenkranz’s view is a Four-Dimensionalist version of the Growing Block Theory or a Three-Dimensionalist version of the theory. I argue that there are three possible ways Correia and Rosenkranz might respond to this question, and I raise several worries for each of those ways. Then I offer some free advice about how I think Correia and Rosenkranz ought to respond to the question.

Many of the leading accounts of what makes a life meaningful are goal-based theories, according to which it is the pursuit of some specific goal (such as love for things that are worthy of love) that gives meaning to our lives. In this chapter I consider how these goal-based theories of meaning in life interact with the two main theories of the nature of time that have been defended in the recent metaphysics literature, namely, The Dynamic Theory of Time and The Static Theory of Time. I argue that The Dynamic Theory fits well with goal-based theories of meaning in life, but The Static Theory does not. Then I close with some thoughts about what a Static Theorist should make of this conclusion.

I argue that time travel to the past is impossible, given a certain metaphysical theory, namely, The Dynamic Theory of Time. I first spell out my particular way of capturing the difference between The Dynamic Theory of Time and its rival, The Static Theory of Time. Next I offer four different arguments for the conclusion that The Dynamic Theory is inconsistent with the possibility of time travel to the past. Then I argue that, even if I am wrong about this, it will still be true that The Dynamic Theory entails that you should not want to travel back to the past. Finally, I conclude by considering a puzzle that arises for those who believe that time travel to the past is metaphysically impossible: What exactly are we thinking about when we seem to be thinking about traveling back in time? For it certainly does not feel like we are thinking about something that is metaphysically impossible.

There is a popular theory in the metaphysics of time according to which time is one of four similar dimensions that make up a single manifold that is appropriately called spacetime. One consequence of this thesis is that changing an object’s orientation in the manifold does not change its intrinsic features. In this paper I offer a new argument against this popular theory. I claim that an especially good performance of a particularly beautiful piece of music, when oriented within the manifold in the normal way, adds to the intrinsic value of the world, but that if the same performance is turned sideways within the manifold, so that it involves a number of different notes spread out in space and all occurring at the same time, then it does not add the same intrinsic value to the world.

In this essay for a PPR book symposium on Theodore Sider's _Four-Dimensionalism<D>, I focus on two of Sider's arguments for four-dimensionalism: (i) his argument from vagueness, and (ii) his argument from time travel. Concerning (i), I first show that Sider's argument commits him to certain strange consequences that many four-dimensionalists may not endorse, and then I discuss an objection that involves appealing to 'brutal composition', the view that there is no informative answer to Peter van Inwagen's 'special composition question'. Concerning (ii), I argue that the three-dimensionalist can account for time travel scenarios in a way that is analogous to Sider's four-dimensionalist account of such scenarios

This book is an accessible introduction to the central themes of contemporary metaphysics. It carefully considers accounts of causation, freedom and determinism, laws of nature, personal identity, mental states, time, material objects, and properties, while inviting students to reflect on metaphysical problems. The philosophical questions discussed include: What makes it the case that one event causes another event? What are material objects? Given that material objects exist, do such things as properties exist? What makes it the case that a person may exist at two different times? An Introduction to Metaphysics makes these tough questions tractable by presenting the features and flaws of current attempts to answer them. Intended primarily for students taking a first class in metaphysics, this lucid and well-written text would also provide an excellent introduction for anyone interested in knowing more about this important area of philosophy.

I believe that time passes. In the last one hundred years or so, many philosophers have rejected this view. Those who have done so have generally been motivated by at least one of three different arguments: (i) McTaggart's argument, (ii) an argument from the theory of relativity, and (iii) an argument concerning the alleged incoherence of talk about the rate of the passage of time. There has been a great deal of literature on McTaggart's argument (although no concensus has been reached).1 There has been a relatively small amount of literature on the argument from the theory of relativity, but this is perhaps not surprising, since most of us philosophers don't understand that theory.2 Meanwhile, there has not been a great deal of literature on the rate of passage argument, and this is surprising, I think, considering that the argument is easy to..

The Theory of Agent Causation has always been formulated as an incompatibilist view, but I think that this has been a mistake. The aim of this paper is to argue that, contrary to what agent causation theorists and their opponents have always believed, the most plausible version of the Theory of Agent Causation is actually a compatibilist version of that theory. I formulate the traditional version of the Theory of Agent Causation, and consider a series of objections to it and related views. With each objection comes a corresponding revision of the theory that is motivated by that objection, and with each revision the theory becomes increasingly compatibilistic until, finally, we arrive at a completely compatibilistic version of the Theory of Agent Causation, which I take to be the most plausible version of that theory.

When do several objects compose a further object? The last twenty years have seen a great deal of discussion of this question. According to the most popular view on the market, there is a physical object composed of your brain and Jeremy Bentham’s body. According to the second-most popular view on the market, there are no such objects as human brains or human bodies, and there are also no atoms, rocks, tables, or stars. And according to the third-ranked view, there are human bodies, but still no brains, atoms, rocks, tables, or stars. Although it’s pleasant to have so many crazy-sounding views around, I think it would also be nice to have a commonsense option available. The aim of this paper is to offer such an option. The approach I offer begins by considering a mereological question other than the standard one that has been the focus of most discussions in the literature. I try to show that the road to mereological sanity begins with giving the most straightforward and commonsensical answer to this other question, and then extending that answer to further questions about the mereology of physical objects. On the approach I am recommending, it turns out that all of the mereological properties and relations of physical objects are determined by their spatial properties and relations.

Since the early part of this century there has been a considerable amount of discussion of the question 'Does time pass?'. A useful way of approaching the debate over the passage of time is to consider the following thesis: The space-time thesis (SPT): Time is similar to the dimensions of space in at least this one respect: there is no set of properties such that (i) these properties are possessed by time, (ii) these properties are not possessed by any dimension of space, and (iii) in virtue of time's possession of these properties it is true to say that time passes. Those who say that time does not pass generally want to affirm something like SPT. But those, on the other hand, who say that time does pass generally want to deny SPT. Of course, SPT is, as it stands, a mere skeleton of a thesis. It needs to be fleshed out. What could the relevant properties be? Why exactly would it be that in virtue of time's possession of these properties it is true to say that time passes? What exactly would it mean to say that time passes? These are all matters that require considerable discussion. The aim of this paper, however, is to take up some linguistic issues that have been considered central to the debate over the passage of time. There are two main reasons why I think it is appropriate to discuss these linguistic issues independently of the relevant metaphysical issues. The first reason is historical: many of the writers who have taken up the issue of whether or not time passes have begun their discussions by focusing on linguistic..

Worlds, Lewis says this: Let us say that something persists iff, somehow or other, it exists at various times; this is the neutral word. Something perdures iff it persists by having different temporal parts, or stages, at different times, though no one part of it is wholly present at more than one time; whereas it endures iff it persists by being wholly present at more than one time. Perdurance corresponds to the way a road persists through space; part of it is here, and part of it is there, and no part is wholly present at two different places. Endurance corresponds to the way a universal, if there are such things, would be wholly present wherever and whenever it is instantiated. Endurance involves overlap: the content of two different times has the enduring thing as a common part. Perdurance does not.1 Lewis's remarks suggest the following formulations of the two views in the 3D/4D controversy.2..

Some people think that pastness, presentness and futurity (and their metric variants, such as being two days past) are genuine propeties of times and events. These putative properties are sometimes called “A properties” and the philosopers who believe in them are often called “A Theorists.” Other philosophers don’t believe in the reality of A properties, but instead say that talk that appears to be about such properties is really about “B relations” – two-place temporal relations like earlier than, simultaneous with, and later than (together with their metric variants, like two days earlier than). The latter philosophers are often called “B Theorists,” and the debate between A Theorists and B Theorists has dominated the philosophy of time since 1908.1 The two views can be put this way. The A Theory: There are genuine, irreducible A properties; talk that appears to be about A properties is not analyzable in terms of B relations.

Since the publication of Peter van Inwagen's book, Material Beings,1 there has been a growing body of philosophical literature on the topic of composition. The main question addressed in both van Inwagen's book and subsequent discussions of the topic is a question that van Inwagen calls "the Special Composition Question." The Special Composition Question is, roughly, the question Under what circumstances do several things compose, or add up to, or form, a single object? For the purposes of formulating a more precise version of the Special Composition Question, we can adopt the following technical terms.

Once upon a time, during a large and international conference of the world's leading philosophers, an angel miraculously appeared and said, "I come to you as a messenger from God. You will be permitted to ask any one question you want - but only one! - and I will answer that question truthfully. What would you like to ask?" The philosophers were understandably excited, and immediately began a discussion of what would be the best question to ask. But it quickly became obvious that they needed more time to discuss the matter, so they asked the angel if he could get back to them. The angel was obliging, and said that he would return at the same time the next day. "But be prepared then," he warned them, "for you will only get this one chance." All of the philosophers gathered at the convention worked at a frenzied pace for the next twenty-four hours, proposing and weighing the merits of various questions. Other philosophers from around the world became involved as well, faxing and emailing their suggestions. Some were in favor of asking the kind of practical question that lots of people might like to know the answer to, such as this one: Q1 Is it better to check your oil when the car is hot or when it is cold? But others said they should not squander this rare opportunity, which gave them a chance to learn something about a truly important and intrinsically interesting topic, and after some discussion it was generally agreed that this was right.
