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' (that is, the same values, desires, and projects). 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.

Propositions has two main goals. The first is to show that there are propositions. The second is to defend an account of their nature. While pursuing these goals, Trenton Merricks draws a variety of controversial conclusions about related issues, including, among others, supervaluationism, the nature of possible worlds, truths about non-existent entities, and whether and how logical consequence depends on modal facts. An argument is modally valid just in case, necessarily, if its premises are true, then its conclusion is true. Propositions begins with the assumption that some arguments are modally valid. Merricks then argues that the premises and conclusions of modally valid arguments are not sentences. Instead, he argues, they are propositions. So, because there are modally valid arguments, there are propositions. Merricks defends the claim that propositions are not structured and are not sets of possible worlds. He thereby presents arguments against the two leading accounts of the nature of propositions. Those arguments are intended not only to oppose those accounts, but also to deliver conclusions about what a satisfactory account of the nature of propositions should say. Of particular importance in this regard are arguments concerning the alleged explanations of how a set of possible worlds or a structured proposition would manage to represent thing as being a certain way. Merricks then defends his own account of the nature of propositions, which says only that each proposition is a necessary existent that essentially represents things as being a certain way.

That there are no white ravens is true because there are no white ravens. And so there is a sense in which that truth 'depends on the world'. But this sort of dependence is trivial. After all, it does not imply that there is anything that is that truth's 'truthmaker'. Nor does it imply that something exists to which that truth corresponds. Nor does it imply that there are properties whose exemplification grounds that truth. Trenton Merricks explores whether and how truth depends substantively on the world or on things or on being. And he takes a careful look at philosophical debates concerning, among other things, modality, time, and dispositions. He looks at these debates because any account of truth's substantive dependence on being has implications for them. And these debates likewise have implications for how and whether truth depends on being. Along the way, Merricks makes a number of new points about each of these debates that are of independent interest, of interest apart from the question of truth's dependence on being. Truth and Ontology concludes that some truths do not depend on being in any substantive way at all. One result of this conclusion is that it is a mistake to oppose a philosophical theory merely because it violates truth's alleged substantive dependence on being. Another result is that the correspondence theory of truth is false and, more generally, that truth itself is not a relation of any sort between truth-bearers and that which 'makes them true'.

There are no statues. Or rocks. Or chairs. Or stars. But there are microscopic objects arranged statuewise and rockwise and chairwise and starwise. Moreover, there are--in addition to microscopic objects arranged humanwise--composite human beings. Or so Trenton Merricks argues.The ontology of Objects and Persons is motivated, in large part, by causal considerations. One of the central ideas is that physical objects are causally non-redundant: physical objects cause things that are not wholly overdetermined by their proper parts. Merricks 'eliminates' statues and other inanimate composite macrophysical objects on the grounds that they would--if they existed--be at best completely causally redundant.Merricks defends our existence by arguing, from certain facts about mental causation, that we human beings cause things that are not overdetermined by our proper parts.A second strand of argument for Merricks's overall ontology involves a variety of philosophical puzzles, puzzles that are dealt with in illuminating and often novel ways.Many other issues are addressed along the way, including free will, the 'reduction' of a composite object to its parts, and the ways in which identity over time can "for practical purposes" be a matter of convention.
