Trenton Merricks presents an original argument for the existence of propositions, and defends an account of their nature. He draws a variety of controversial conclusions, for instance about supervaluationism, the nature of possible worlds, truths about non-existent entities, and whether and how logical consequence depends on modal facts.

Suppose that time t is just a few moments from now. And suppose that the proposition that Jones sits at t was true a thousand years ago. Does the thousand-years-ago truth of that proposition imply that Jones's upcoming sitting at t will not be free? This article argues that it does not. It also argues that Jones even now has a choice about the thousand-years-ago truth of that Jones sits at t . Those arguments do not require the complex machinery (...) of Ockhamism, with its distinction between hard facts and soft facts; indeed, those arguments do not require any complex machinery at all. Instead, those arguments are built on an uncontroversial understanding of the idea that truth depends on the world. In the final section of the article, those arguments are extended to show that foreknowledge of an action does not threaten that action's freedom. (shrink)

Objects and Persons presents an original theory about what kinds of things exist. Trenton Merricks argues that there are no non-living inanimate macrophysical objects -- no statues or rocks or chairs or stars -- because they would have no causal role over and above the causal role of their microphysical parts. Humans do exist: we have non-redundant causal powers. Along the way, Merricks has interesting things to say about mental causation, free will, and various philosophical puzzles. Anyone (...) working in metaphysics will enjoy this lucid and provocative book. (shrink)

other things, that the Vagueness Argument for unrestricted composition fails. In ‘Vagueness and Arbitrariness: Merricks on Composition’, Elizabeth Barnes objects to my argument. This paper replies to Barnes, and also offers further support for the views defended in my original paper.

Truth and Ontology concludes that some truths do not depend on being in any substantive way at all.

The personal identity literature is fragmented. There is a literature on the normative topic of 'what matters in survival'. And there is a separate literature on the metaphysics of persons. But in Self and Identity, Trenton Merricks shows that some important claims about personal identity cannot even be articulated, much less evaluated, unless these topics are brought together. Merricks says that what matters in survival is constituted by its being appropriate for a present person to first-personally anticipate, (...) and have self-interested concern with regard to, a future person's experiences. So what matters in survival is not constituted by identity with a future person. So identity is not what matters in survival. But Merricks argues that--given a metaphysics of 'enduring' persons--identity with a future person explains why it is appropriate to first-personally anticipate, and have self-interested concern with regard to, that person's experiences. So identity delivers what matters in survival. Some claim that what matters in survival is delivered not by identity, but instead by psychological continuity. Or by having the 'same self'. Or by narrative connectedness. Or by unity of agency. Merricks argues that these claims--unlike the claim that identity delivers what matters in survival--cannot accommodate all the ways in which personal transformations can be good, or bad, for someone. At the end of Self and Identity, Merricks puts his conclusions about what matters in survival through their paces by applying them to a new topic: personal immortality. (shrink)

I show that the arguments of Ch. 2, while giving good reasons to eliminate statues and other inanimate composita, do not provide equally good reasons to eliminate us human organisms. As with Ch. 2, the arguments discussed touch on a variety of topics, including vagueness and the ‘Sorites Game,’ worries about co‐location and constitution, and the way a thinker is related to her brain.

This article focuses on two questions about the doctrine of the resurrection, questions that will occur to most philosophers and theologians interested in identity in general, and in personal identity in particular. The first question is: how? How could a body that at the end of this life was frail and feeble be the very same body as a resurrection body, a body which will not be frail or feeble, but will instead be glorified? Moreover, how could a body that (...) has passed out of existence – perhaps as a result of decay or cremation – come back into existence on the Day of Resurrection? The second question is: why? Why would anyone want a resurrection of the body? And even if the resurrection delivers something that we want – maybe one's current body has some sentimental value and so having it back would be nice – we might still wonder why any religion would give the doctrine a central place, as Judaism, Christianity, and Islam all do.

Being conscious is intrinsic. Suppose P, a conscious human being, “shrinks” by losing an atom from her left index finger. Suppose that at the very first instant at which P has lost that atom, the atoms that then compose her remain just as they were immediately before “the loss.” This implies—assuming MS for reductio—that, just as those atoms compose a conscious object after the loss, so they composed a conscious object before the loss. Name that latter object ‘the atom-complement’.

The doctrine of Microphysical Supervenience (MS) states that: Necessarily, if atoms A1 through An compose an object that exemplified intrinsic qualitative properties Q1 through Qn, then atoms like A1 through An (in all their respective intrinsic qualitative properties), related to one another by all the same restricted atom-to-atom relations as A1 through An, compose an object that exemplifies Q1 through Qn. I show that MS entails a contradiction and so must be rejected. And my argument against MS provides the resources (...) to show that Global Microphysical Supervenience (GMS) is false. GMS states that possible worlds qualitatively exactly alike at the microphysical level are qualitatively exactly alike at the macrophysical level. (shrink)

These comments were presented as part of an exchange with Peter van Inwagen in January of 2014 during the California Metaphysics Conference at the University of Southern California. They have not been updated or changed since their presentation. (I refer to van Inwagen as ‘Peter’, which I would not do in a published paper. I make some jokey remarks that might have been sort of alright if you heard them only once spoken aloud, but as I read them now make (...) me cringe a bit. And so on.) These comments were never published. (shrink)

‘Restricted composition’ says that there are some composite objects. And it says that some objects jointly compose nothing at all. The main threat to restricted composition is the influential and widely defended Vagueness Argument. We shall see that the Vagueness Argument fails. In seeing how this argument fails, we shall discover a new focus for the debate over composition's extent.

This paper argues that if persons last over time by “enduring”, then no analysis or reduction of personal identity over time in tenus of any sort of psychological continuity can be correct. In other words, any analysis of personal identity over time in tenus of psychological continuity entails that persons are four-dimensional and have temporal parts. The paper then shows that if we abandon psychological analyses of personal identity---as we must if persons endure---Parfit’s argument for the claim that identity does (...) not matter in survival is easily undenuined. The paper then suggests that this offers support for the claim that persons endure. Along the way the paper tries to clarify the contrast between the doctrine that persons endure and its rival, four-dimensionalism. (shrink)

Warrant is “that, whatever precisely it is, which makes the difference between knowledge and mere true belief.” S knows that p, therefore, if and only if S’s belief that p is warranted and p is true. This is a purely formal characterization of warrant. Warrant may, no doubt, be a messy item: a substantive analysis might be full of disjuncts and conjuncts and conditionals and caveats. But if there are true beliefs that are not knowledge, then there is something that (...) all beliefs that are knowledge share, and all merely true beliefs lack. This is warrant. I want to argue that warrant, whatever it is that makes the difference between mere true belief and knowledge, entails truth. (shrink)

According to one account, vagueness is "metaphysical." The friend of metaphysical vagueness believes that, for some object and some property, there can be no determinate fact of the matter whether that object exemplifies that property. A second account maintains that vagueness is due only to ignorance. According to the epistemic account, vagueness is explained completely by and is nothing over and above our not knowing some relevant fact or facts. These are the minority views. The dominant position maintains that there (...) is a third possible variety of vagueness, linguistic vagueness. And, it goes on to insist, all vagueness is of this third variety. I shall argue, however, that linguistic vagueness is not a third variety of vagueness. Either it is a species of metaphysical vagueness or a kind of ignorance. And this, I argue, makes trouble for the claim that all vagueness is linguistic. (shrink)

The bulk of the essay “Truth and Freedom” (Philosophical Review 118 [2009]: 29–57) opposes fatalism, which is the claim that if there is a true proposition to the effect that an action A will occur, then A will not be free. But that essay also offers a new way to reconcile divine foreknowledge and human freedom. In “The Truth about Freedom: A Reply to Merricks” (Philosophical Review 120 [2011]: 97–115), John Martin Fischer and Patrick Todd raise a number of (...) objections to “Truth and Freedom,” most of which are objections to its treatment of foreknowledge. Their central complaint seems to be that that treatment is, despite its claims to the contrary, merely a form of Ockhamism—and a poorly developed form of Ockhamism at that. This essay replies to Fischer and Todd's specific objections. But, more importantly, it further clarifies the fundamental differences between the way it reconciles divine foreknowledge and human freedom and the Ockhamist's way. In particular, this essay further demonstrates that when it comes to divine foreknowledge's compatibility with human freedom, the fundamental question is not the Ockhamist's question of whether God's beliefs about what an agent will do in the future are “hard facts.” Rather, the fundamental question is whether God's beliefs about what an agent will do in the future depend on what that agent will do in the future.

Further clarifies eliminativism, and further demonstrates its intelligibility, by showing eliminativism's novel and interesting solutions to a number of philosophical puzzles. The arguments of this chapter also support the truth of eliminativism. The arguments touch on a variety of topics, including vagueness and the ‘Sorites Game,’ worries about co‐location and constitution, and the way a thinker is related to her brain.

Folk ontology includes statues. Eliminativism denies that statues exist but says that there are atoms arranged statuewise. In this chapter, I explain eliminativism and define ‘arranged statuewise’. I also argue that eliminativism is neither obviously false nor contradictory. In presenting this argument, I consider, among other things, ‘reductionism’ and composition as identity.

Warrant is that, whatever it is, which makes the difference between knowledge and mere true belief. In "Warrant Entails Truth" (PPR, December 1995), I argued that it is impossible that a false belief be warranted. Sharon Ryan attacked the argument of that paper in her "Does Warrant Entail Truth?" (PPR, March 1996). In "More on Warrant's Entailing Truth" I present arguments for the claim that warrant entails truth that are, I think, significantly more compelling than the arguments of my original (...) "Warrant Entails Truth." This paper responds to Ryan's objections, but it is not merely a reply to Ryan's article. It is, rather, a free-standing defense of warrant's entailing truth that is the product of discussion and argument for over two years with many philosophers, including Ryan, over the arguments contained in my original paper.

Like many others interested in Derek Parfit’s work, I’ve been awaiting this collection of original essays on Reasons and Persons, having placed an order with my bookstore at least a year before the book was finally published. The delay was due to the editor’s original plan of including Parfit’s responses, a plan that had to be abandoned. Eventually, Jonathan Dancy tells us, Parfit will publish responses to these pieces. And at least one response has already appeared in print, Parfit’s discussion (...) of Mark Johnston’s contribution to the—then forthcoming—Dancy volume. So the bad news is that all of these essays were in their completed form five or six years before the book was published; as a result, the arguments sometimes seem a little bit familiar and, of course, neither profit from nor engage the most recent literature on the topics they address.
