Recently, I’ve championed the doctrine that fundamentally different sorts of things exist in fundamentally different ways.1 On this view, what it is for an entity to be can differ across ontological categories.2 Although historically this doctrine was very popular, and several important challenges to this doctrine have been dealt with, I suspect that contemporary metaphysicians will continue to treat this view with suspicion until it is made clearer when one is warranted in positing different modes of existence.3 I address this (...) concern here. The question of when to posit ways of being is closely related to a more general question: when should one think that some philosophically interesting expression is analogous? Accordingly, my strategy here is as follows. First, I briefly explain my interpretation of ontological pluralism, the doctrine that there are ways of being.4 Second, I introduce the notion of an analogous term, and show how, on most ways of implementing ontological pluralism, “existence” is analogous. Third, I discuss two sufficient conditions for when one is warranted in claiming that a philosophically interesting term is analogous. Fourth, I present a series of ontological schemes, each of which satisfies at least one of the sufficient conditions. The upshot is this: if you are attracted to one of these ontologies, you have reason to believe in ways of being. The careful reader will have noted the apparent modesty of my conclusion. Unfortunately, I do not believe that one could ever be rationally required to believe in ways of being. Still, in general a metaphysic is a live option to the extent that it is shown to be rationally permissible to believe. Since the apparent consensus among contemporary analytic metaphysicians is that believing that things can exist in different ways is silly or confused, establishing the rational permissibility of belief in ways of being is a non-trivial task. Let us begin. (shrink)

I am attracted to ontological pluralism, the doctrine that some things exist in a different way than other things.1 For the ontological pluralist, there is more to learn about an object’s existential status than merely whether it is or is not: there is still the question of how that entity exists. By contrast, according to the ontological monist, either something is or it isn’t, and that’s all there is say about a thing’s existential status. We appear to be to be (...) ontological committed to what I will call almost nothings. Examples of almost nothings include holes, cracks, and shadows; almost nothings thrive in the absence of ‘positive’ entities such as donuts, walls, and sunlight. Let’s focus on holes, since the literature on them is voluminous.2 We quantify over holes, and even count them: we say, for example, that there are some holes in the cheese, seven to be precise. We ascribe features to them and talk as though they stand in relations: that hole is three feet wide, much wider than that tire over there. Holes apparently persist through time, as evidenced by the fact that my sweater has the same hole in it as the last time you saw me wear it. We even talk as though holes are causally efficacious: my ankle was badly sprained because I stepped in that hole in the sidewalk.3 It seems then that we believe in holes. If our beliefs are true, holes must enjoy some kind of reality. This puts the ontological monist in an uncomfortable position. According to her, everything that there is enjoys the same kind of reality, which is the kind of reality enjoyed by full-fledged concrete entities such as ourselves. She is committed to the unpleasant claim that holes are just as real as concretia, a claim that is apt to be met with incredulous stares by those not acquainted with contemporary metaphysics. Roy Sorensen (2008, p. 19) notes the tension almost nothings generate for ontological monists: ‘… it feels paradoxical to say that absences exist—but no better to say that absences do not exist’..

Composition as Identity is the view that, in some sense, a whole is numerically identical with its parts. Compositional universalism is the view that, whenever there are some things, there is a whole composed of those things. Despite the claims of many philosophers, these views are logically independent. Here, I will show that composition as identity does not entail compositional universalism.

Philosophical questions concerning parts and wholes have received a tremendous amount of the attention of contemporary analytic metaphysicians. In what follows, I discuss some of the central questions. The questions to be discussed are: how general is parthood? Are there different kinds of parthood or ways to be a part? Can two things be composed of the same parts? When does composition occur? Can material objects gain or lose parts? What is the logical form of the parthood relation enjoyed by (...) material objects? (shrink)

The problem of qualitative heterogeneity is to explain how an extended simple can enjoy qualitative variation across its spatial or temporal axes, given that it lacks both spatial and temporal parts. I discuss how friends of extended simples should address the problem of qualitative heterogeneity. I present a series of arguments designed to show that rather than appealing to fundamental distributional properties one should appeal to tiny and short-lived tropes. Along the way, issues relevant to debates about material composition, persistence (...) over time and existence monism are discussed.  . (shrink)

Friends of states of affairs and structural universals appeal to a relation, structure-making, that is allegedly a kind of composition relation: structure-making ?builds? facts out of particulars and universals, and ?builds? structural universals out of unstructured universals. D. M. Armstrong, an eminent champion of structures, endorses two interesting theses concerning composition. First, that structure-making is a composition relation. Second, that it is not the only (fundamental) composition relation: Armstrong also believes in a mode of composition that he calls mereological, and (...) which he takes to be the only kind of composition recognized by his philosophical adversaries, such as David Lewis. Armstrong, accordingly, is a kind of pluralist about compositional relations: there is more than one way to make wholes from parts. In this paper, I critically evaluate Armstrong's compositional pluralism. (shrink)

There are many kinds of beings – stones, persons, artifacts, numbers, propositions – but are there also many kinds of being? The world contains a variety of objects, each of which exists – but do some objects exist in different ways? The historically popular answer is yes. This answer is suggested by the Aristotelian slogan that “being is said in many ways”, and according to some interpretations is Aristotle’s view.1 Variants of this slogan were championed by medieval philosophers, such as (...) Aquinas, who worried that God cannot be said to exist in the same sense (or in the same way?) as created things.2 Descartes alluded to the medievals’ worry, but extensive discussion of the problem of being disappeared from the central stage by the time of the modern period.3 However, in the early 20th century, friends of ways of being included Alexius Meinong (1910: 49- 62), G.E. Moore (1903: 161-163), Russell (1912: 91-100), Husserl (1901: 249-250), and Heidegger (1927).4 In what follows, I develop a meta-ontological theory based on the work of Martin Heidegger circa Being and Time. I take Heidegger’s work as my inspiration because of the historical importance of Heidegger’s philosophy, and because Heidegger provides a particularly clear statement of the doctrine that there are many ways to be. I begin by carefully discussing and then formulating the relevant aspects of Heidegger’s metaontological theory. Heidegger claims both that the word “being” has many meanings and that there are different ways in which things exist. Section 2 explicates the former thesis, as well as elucidates the connection between senses of “being” and quantification. Most contemporary analytic metaphysicians believe that the idea that different kinds of beings can enjoy different ways of being is metaphysically bankrupt, and probably even meaningless.5 They are mistaken. In section 3, I discuss the doctrine that there are ways of being, and show how we can understand this doctrine in terms of the meta-ontological framework defended by Theodore Sider.. (shrink)

The claim that composition is identity is an intuition in search of a formulation. The farmer’s field is made of six plots, and in some sense is nothing more than those six plots. According to the friend of composition as identity, the six plots are identical with the farmer’s field.1 Some philosophers, such as Peter van Inwagen (1994), have claimed that the view that composition is identity is incoherent. Van Inwagen cites the apparent ungrammaticality of sentences like ‘the six plots (...) are the farmer’s field’ as evidence for his view. Perhaps van Inwagen is right, but I needn’t settle this question here. I will argue against the view that composition is identity, whatever that view amounts to, in the following way. First, I will elucidate a principle called ‘the Plural Duplication Principle’ [PDP]. Any acceptable way of making sense of the slogan that composition is identity— i.e., any way that properly conforms to the intuitions that lead one to utter this slogan— must validate PDP. Second, I argue that PDP is false. So any acceptable way of making sense of the slogan that composition is identity is false. The slogan that composition is identity will be refuted prior to being properly formulated. Following David Lewis (1986: 59-63), let us say that x and y are duplicates just in case there is a 1-1 correspondence between their parts that preserves perfectly natural properties and relations. Suppose that A is identical with B. Then any duplicate of A must also be a duplicate of B. This follows via Leibniz’s Law: if some duplicate of A were not.. (shrink)

It is not at all obvious how best to draw the distinction between conditional and unconditional desires. In this paper we examine extant attempts to analyse conditional desire. From the failures of those attempts, we draw a moral that leads us to the correct account of conditional desires. We then extend the account of conditional desires to an account of all desires. It emerges that desires do not have the structure that they have been thought to have. We attempt to (...) explain the distinction between intrinsic and extrinsic desire in light of our account of desire. We show how to use our account to solve Wollheim's paradox of democracy and to save modus ponens. Finally, we extend the account of desire to related phenomena, such as conditional promises, intentions, and commands. (shrink)

I argue that extended simples are possible. The argument given here parallels an argument given elsewhere for the claim that the shape properties of material objects are extrinsic, not intrinsic as is commonly supposed. In the final section of the paper, I show that if the shape properties of material objects are extrinsic, the most popular argument against extended simples fails.

Suppose that a material object is gunky: all of its parts are located in space, and each of its parts has a proper part. Does it follow from this hypothesis that the space in which that object resides must itself be gunky? I argue that it does not. There is room for gunky objects in a space that decomposes without remainder into mereological simples.

Possibilism—the view that there are non-actual, merely possible entities—is a surprisingly resilient doctrine.1 One particularly hardy strand of possibilism—the modal realism championed by David Lewis—continues to attract both foes who seek to demonstrate its falsity (or at least stare its advocates into apostasy) and friends who hope to defend modal realism (or, when necessary, modify modal realism so as to avoid problematic objections).2 Although I am neither a foe nor friend of modal realism (but some of my best friends are!), (...) like many I continue to be fascinated by the doctrine.

In this paper, I formulate, elucidate, and defend a version of modal realism with overlap , the view that objects are literally present at more than one possible world. The version that I defend has several interesting features: (i) it is committed to an ontological distinction between regions of spacetime and material objects; (ii) it is committed to compositional pluralism , which is the doctrine that there is more than one fundamental part-whole relation; and (iii) it is the modal analogue (...) of endurantism , which is the doctrine that objects persist through time by being wholly present at each moment they are located.

In a recent paper titled 'Simples', Ned Markosian asks and answers the Simple Question, which is, 'under what circumstances is it true of some object that it has no proper parts?' Markosian's answer to the simple question is MaxCon , which states that an object is a simple if and only if it is a maximally continuous object. I present several arguments against MaxCon.

In a recent paper, Stephen Barker and Phil Dowe (2003)1 argue that multilocation is impossible. An object enjoys multi-location just in case it is wholly present at more than one (distinct) space-time region (106). One popular view that is committed to multi-located objects is endurantism, the doctrine that objects persist through time by being wholly present at each time they are located.2 So if Barker and Dowe are right, endurantism is in big trouble.

I argue that a solution to puzzles concerning the relationship ofobjects and their properties – a version of the `bundle' theory ofparticulars according to which ordinary objects are mereologicalfusions of monadic and relational tropes – is also a solution topuzzles of material constitution involving the allegedco-location of material objects. Additionally, two argumentsthat have played a prominent role in shaping the current debate,Mark Heller's argument for Four Dimensionalism and Peter vanInwagen's argument against Mereological Universalism, are shownto be unsound given this version (...) of the bundle theory.
