Do causes necessitate their effects? Causal necessitarianism is the view that they do. One major objection—the “monotonicity objection”—runs roughly as follows. For many particular causal relations, we can easily find a possible “blocker”—an additional causal factor that, had it also been there, would have prevented the cause from producing its effect. However—the objection goes on—, if the cause really necessitated its effect in the first place, it would have produced it anyway—despite the blocker. Thus, CN must be false. Though different (...) from Hume’s famous attacks against CN, the monotonicity objection is no less important. In one form or another, it has actually been invoked by various opponents to CN, past and present. And indeed, its intuitive appeal is quite powerful. Yet, this paper argues that, once carefully analysed, the objection can be resisted—and should be. First, I show how its success depends on three implicit assumptions concerning, respectively, the notion of cause, the composition of causal factors, and the relation of necessitation. Second, I present general motivations for rejecting at least one of those assumptions: appropriate variants of them threaten views that even opponents to CN would want to preserve—in particular, the popular thesis of grounding necessitarianism. Finally, I argue that the assumption we should reject is the one concerning how causes should be understood: causes, I suggest, include an element of completeness that excludes blockers. In particular, I propose a way of understanding causal completeness that avoids common difficulties. (shrink)

A central dispute in social ontology concerns the existence of group minds and actions. I argue that some authors in this dispute rely on rival views of existence without sufficiently acknowledging this divergence. I proceed in three steps in arguing for this claim. First, I define the phenomenon as an implicit higher-order disagreement by drawing on an analysis of verbal disputes. Second, I distinguish two theories of existence—the theory-commitments view and the truthmaker view—in both their eliminativist and their constructivist variants. (...) Third, I examine individual contributions to the dispute about the existence of group minds and actions to argue that these contributions have an implicit higher-order disagreement. This paper serves two purposes. First, it is a study to apply recent advances in meta-ontology. Second, it contributes to the debate on social ontology by illustrating how meta-ontology matters for social ontology. (shrink)

In this paper I develop a theological account of intrinsic value drawn from some passages in Robert Merrihew Adams’ book Finite and Infinite Goods. First I explain why Adams’ work on this topic is interesting, situate his theory within the broader literature on intrinsic value, and draw attention to some of its revisionist features. Next I state the theory, raise some problems for it, and refine it in light of those problems. Then I illustrate how the refined theory works by (...) showing that it has the resources to deal with some seemingly formidable objections. (shrink)

This paper raises the question under what circumstances a plurality forms a set, parallel to the Special Composition Question for mereology. The range of answers that have been proposed in the literature are surveyed and criticised. I argue that there is good reason to reject both the view that pluralities never form sets and the view that pluralities always form sets. Instead, we need to affirm restricted set formation. Casting doubt on the availability of any informative principle which will settle (...) which pluralities form sets, the paper concludes by affirming a naturalistic approach to the philosophy of set theory.

Michael Dummett offered a semantic characterisation of a variety of realism-antirealism debates. This approach has fallen out of fashion. This has been to the detriment of metaphysics. This paper offers an accurate characterisation of Dummett’s view, often lacking in the literature, and then defends it against a range of attacks (from Devitt, Miller and Williamson). This understanding of realism debates is resilient, and if we take it seriously the philosophical terrain looks importantly different. In particular, the philosophy of language has (...) a foundational role with respect to metaphysics. (shrink)

It is common for contemporary ontologists to claim that they are not concerned with what exists simpliciter, but rather with what exists ’fundamentally’, or what ’really’ exists. I argue that positions of this sort cannot satisfy reasonable constraints concerning the acquisition of language. I assess and dismiss possible responses to this complaint before commenting on the prospects for a metaphysics without bespoke existence claims.

The paper offers a new account of Spinoza's conception of “substance”, the fundamental building block of reality. It shows that it can be demonstrated apriori within Spinoza's metaphysical framework that (i) contrary to Idealist readings, for Spinoza there can be no substance that is not determined or modified by some other entity produced by substance; and that (ii) there can be no substance (and hence no being) that is not a thinking substance.

ABSTRACTThe Ant Trap is a terrific book, which opens up new opportunities to use philosophical methods in the social realm, by drawing on the tools and techniques of contemporary metaphysics. Epstein uses concepts of dependence, constitution, and grounding, of parts and whole, of membership and kindhood, both to clarify existing accounts of social reality and to develop an account of his own. Whilst I admire the general strategy, I take issue with some aspects of Epstein’s implementation, notably his distinction between (...) grounding and anchoring. I recommend that he give up this distinction, which is not crucial to his project. (shrink)

Saying so can make it so, J. L. Austin taught us long ago. Famously, John Searle has developed this Austinian insight in an account of the construction of institutional reality. Searle maintains that so-called Status Function Declarations, allegedly having a “double direction of fit”, synchronically create worldly institutional facts, corresponding to the propositional content of the declarations. I argue that Searle’s account of the making of institutional reality is in tension with the special theory of relativity—irrespective of whether the account (...) is interpreted as involving causal generation or non-causal grounding of worldly institutional facts—and should be replaced by a more modest theory which interprets the results of Status Function Declarations in terms of mere Cambridge change and institutional truth. I end the paper by indicating the import of this more modest theory for theorizing about the causal potency of institutional phenomena generated by declarations. (shrink)

A method of supervaluation for Kripke’s theory of truth is presented. It differs from Kripke’s own method in that it employs trees; results in a compositional semantics; assigns the intuitively correct truth values to the sentences of a particularly tricky example of Gupta’s; and – it is argued – is acceptable as an explication of the correspondence theory of truth.

Setting off from a familiar distinction in the philosophy of properties, this paper introduces a tripartite distinction between sparse causation, abundant causation and mere abundant causation. It is argued that the contrast between sparse and mere abundant causation allows us to resolve notorious philosophical issues having to do with negative causation, causation involving institutional properties and physical macro-causation in a way that is unified, intuitive and in line with scientific doctrines and practices.

A modification of Kripke’s theory of truth is proposed and it is shown how this modification solves some of the problems of expressive weakness in Kripke’s theory. This is accomplished by letting truth values be grounded in facts about other sentences’ ungroundedness.

This paper presents a characterization of the ontological dependence relation between an existent and its sustaining cause, which allows to straightforwardly deduce that the being of any dependent existent is grounded on an independent one. Furthermore, an argument is given to the conclusion that there is a unique independent existent, which is therefore the ultimate ground of being.

A number of philosophers have recently found it congenial to talk in terms of grounding. Grounding discourse features grounding sentences that are answers to questions about what grounds what. The goal of this article is to explore and defend a counterpart-theoretic interpretation of grounding discourse. We are familiar with David Lewis's applications of the method of counterpart theory to de re modal discourse. Counterpart-theoretic interpretations of de re modal idioms and grounding sentences share similar motivations, mechanisms, and applications. I shall (...) explain my motivations and describe two applications of a counterpart theory for grounding discourse. But, in this article, my main focus is on counterpart-theoretic mechanisms.

When the meta-philosophies of Nominalism and Realism are compared, it is often said that Nominalism is motivated by a methodology of ontological economy, while Realism would be motivated by an appeal to Common Sense. In this paper, I argue that this association is misguided. After briefly comparing the meta-philosophy of Common Sense and the meta-philosophy of economy, I show that the core motivation in favour of Realism relies in fact in a principle of economy which violates the methodology of Common (...) Sense. I conclude that Common Sense philosophers should endorse Nominalism. (shrink)

This paper is concerned with the relation between two important metaphysical notions, ‘truthmaking’ and ‘grounding’. I begin by considering various ways in which truthmaking could be explicated in terms of grounding, noting both strengths and weaknesses of these analyses. I go on to articulate a problem for any attempt to analyze truthmaking in terms of a generic and primitive notion of grounding based on differences we find among examples of grounding. Finally, I outline a more complex view of how truthmaking (...) and grounding could relate. On the view explored, truthmaking is a species of grounding differentiated from other species of grounding by the unique form of dependence it involves. (shrink)

The aim of this paper is to bring recent work on metaphysical grounding to bear on the phenomenon of social construction. It is argued that grounding can be used to analyze social construction and that the grounding framework is helpful for articulating various claims and commitments of social constructionists, especially about social identities, e.g., gender and race. The paper also responds to a number of objections that have been leveled against the application of grounding to social construction from Elizabeth Barnes, (...) Mari Mikkola, and Jessica Wilson. (shrink)

The goal of this paper is to make headway on a metaphysics of social construction. In recent work, I’ve argued that social construction should be understood in terms of metaphysical grounding. However, I agree with grounding skeptics like Wilson that bare claims about what grounds what are insufficient for capturing, with fine enough grain, metaphysical dependence structures. To that end, I develop a view on which the social construction of human social kinds is a kind of realization relation. Social kinds, (...) I argue, are multiply realizable kinds. I depart from the Wilson by further arguing that an appeal to grounding is not otiose when it comes to social construction. Social construction, I claim, belongs to the “big-G” Grounding genus, but it is the specific “small-g” relation of realization at work in cases of human kind social construction. (shrink)

Metaphysics is the branch of philosophy that aims to give a theoretical account of what there is and what it is like. Social justice movements seek to bring about justice in a society by changing policy, law, practice, and culture. Evidently, these activities are very different from one another. The goal of this article is to identify some positive connections between recent work in metaphysics and social justice movements. I outline three ways in which metaphysical work on social reality can (...) make a contribution to movements seeking social justice, viz., (1) by providing basic categories and concepts useful for clarifying and defending claims made by social justice movements; (2) by offering accounts of the natures of social categories, structures, and institutions that these movements seek to change; and (3) by contributing to “unmasking” or “debunking” projects that reveal putatively natural arrange- ments to be social in nature and hence subject to moral critique, alteration, and possibly eradication.

Analogical reasoning projects a property taken to hold of something or things (the source) to something else (the target) on the basis of just those similarities premised in the analogy. Standard similarity-based accounts of analogical reasoning face the question: Under what conditions does a collection of similarities sufficiently warrant analogical projection? One answer is: When a thing’s having the premised similarities somehow determines its having the projected property. Standardly, this answer has been interpreted as claiming that a formally defined determination (...) relation exists between the variables of which the determining properties are values and the variable of which the determined property is a value. This paper supplies another answer: Analogical projection is warranted when an item’s having the projected property is grounded in its having the premised similarities. Drawing on the metaphysics of grounding, we propose a model of grounded analogy on which analogical reasoning is valid under metaphysical necessity. Our model thus provides one answer to John Stuart Mill’s question of how analogical reasoning based on limited information about a single source case can provide an indefeasible justification for analogical projection. Once a relation of total grounding is ascertained to hold between some similarities and the projected property, no other properties bear on the projectability of the projected property from the source to the target.

According to the deductive-nomological account of ground, a fact A grounds another fact B in case the laws of metaphysics determine the existence of B on the basis of the existence of A. Accounts of grounding of this particular variety have already been developed in the literature. My aim in this paper is to sketch a new version of this account. My preferred account offers two main improvements over existing accounts. First, the present account is able to deal with necessitarian (...) as well as non-necessitarian cases of grounding by acknowledging the existence of two types of metaphysical laws. I will argue that we should assume that metaphysical laws come in the necessitarian as well as in the non-necessitarian varietyclosely paralleling the distinction between strict and non-strict laws in the philosophy of science. The second main improvement of the present account is that this account is able to provide an explanation of why the laws of metaphysics have a direction built into them. I will argue that we should characterize metaphysical laws with the help of Theodore Sider’s (2011) notion of structure, which is a descendent of David Lewis’s (1983) notion of naturalness. According to the account of metaphysical laws developed in this paper, metaphysical laws express in their antecedents either perfectly structural truths or more structural truths than in their consequents. Since on Sider’s account structural features of reality are fundamental features of reality, the account is able to explain as to why the laws of metaphysics take us from the fundamental to the derivative.

Attempts to explicate the substance-property nexus are legion in the philosophical literature both historical and contemporary. In this paper, I shall attempt to impose some structure into the discussion by exploring ways to combine two unlikely bedfellows—Platonic properties and Aristotelian substances. Special attention is paid to the logical structure of substances and the metaphysics of property exemplification. I shall argue that an Aristotelian-Platonic account of the substance-property nexus is possible and has been ably defended by contemporary philosophers.

Most of the most prominent discussions within metaphysics assume without argument that our metaphysical theorizing should be constrained by classical logic. I examine why this is the case and then argue that it should not be. That is, I argue that we should not take our metaphysical theorizing to be constrained by classical logic.

In the first argument of Metaphysics Μ.2 against the Platonist introduction of separate mathematical objects, Aristotle purports to show that positing separate geometrical objects to explain geometrical facts generates an ‘absurd accumulation’ of geometrical objects. Interpretations of the argument have varied widely. I distinguish between two types of interpretation, corrective and non-corrective interpretations. Here I defend a new, and more systematic, non-corrective interpretation that takes the argument as a serious and very interesting challenge to the Platonist.

Analytic Philosophy, EarlyView. The method of paraphrasing away apparent ontological commitments is a familiar tool for trimming one's ontology. Even so, I argue that aiming to avoid commitment via paraphrase is unjustified. The reason is the standard motivations for paraphrase rest on implicit yet faulty principles regarding ontological categories and categorization- or so I argue. These results also provide indirect support for a permissivist approach to ontology.

The central claim of this paper is that the Aristotelian metaphysics of objects is incompatible with physicalism. This includes the contemporary variant of Aristotelianism I call ‘sortalism’. The core reason is that an object’s identity as an instance of a (natural) kind, as well as its consequent persistence conditions, is neither physically fundamental nor determined by what is physically fundamental. The argument for the latter appeals to what is commonly known as ‘the grounding problem’; in particular I argue that the (...) physicalist has no solution, and this requires that the physicalist jettison the traditional concept of objects having kind-specific identity and persistence conditions. (shrink)

A world where there exists n concrete things is a count-determinate world. The orthodox view is count-determinacy is necessary; if to be is to be the value of a variable and the domain of quantification is enumerable, count-determinacy follows. Yet I argue how many there are can be indeterminate; count-indeterminacy is metaphysically possible and even likely actual. Notably, my argument includes rebuttals of Evans’ reductio of indeterminate identity and the Lewis/Sider ‘argument from vagueness’. Count-indeterminacy should therefore be recognized as another (...) basic form of genuine metaphysical indeterminacy, in addition to types recently defend by Barnes, Williams, and Wilson. (shrink)

Philosophers have observed that metaphysical necessity appears to be a true or real or genuine form of necessity while epistemic necessity does not. Similarly, natural necessity appears genuine while deontic necessity does not. But what is it for a form of necessity to be genuine? I defend an account of genuine necessity in explanatory terms. The genuine forms of necessity, I argue, are those that provide what I call necessitarianexplanation. I discuss the relationship of necessitarian explanation to ground.

Recent years have seen an explosion of interest in metaphysical explanation, and philosophers have fixed on the notion of ground as the conceptual tool with which such explanation should be investigated. I will argue that this focus on ground is myopic and that some metaphysical explanations that involve the essences of things cannot be understood in terms of ground. Such ‘essentialist’ explanation is of interest, not only for its ubiquity in philosophy, but for its being in a sense an ultimate (...) form of explanation. I give an account of the sense in which such explanation is ultimate and support it by defending what I call the inessentiality of essence. I close by suggesting that this principle is the key to understanding why essentialist explanations can seem so satisfying. (shrink)

Priority monism is the doctrine that there is exactly one substance: the whole concrete cosmos. This paper develops an objection to priority monism. The objection is that although every substance is necessarily a substance, for the priority monist the cosmos is not necessarily a substance. It follows that the cosmos is not a substance and so priority monism is false. The priority monist's pluralist opponent, I argue, can avoid a parallel objection to her view.

Dispositional essentialism is the view that all or many fundamental properties are essentially dispositional, orpowers. The literature on the dispositional essence of powers is abundant. In contrast, the question of how to understand the fundamentality of fundamental powers has received scarce interest. Therefore, the fundamentality of powers stands in need of clarification. There are four main conceptions of the fundamental, namely as that which is (i)metaphysically independent; or (ii)belonging to a minimally complete basis; or (iii)perfectly natural; or (iv)metaphysically primitive. Here, (...) I present and discuss each of these approaches from the viewpoint of dispositional essentialism. I show that (i) is incompatible with the metaphysics of powers and (ii)–(iv) have more drawbacks than merits. Therefore, my conclusion is that the dispositional essentialist should seek an alternative. Although I offer no positive account, I pave the way to more fruitful views by identifying the shortcoming of these unpromising options. (shrink)

Establishing Dispositionalism as a viable theory of modality requires the successful fulfilment of two tasks: showing that all modal truths can be derived from truths about actual powers, and offering a suitable metaphysics of powers. These two tasks are intertwined: difficulties in one can affect the chances of success in the other. In this paper, I generalise an objection to Dispositionalism by Jessica Leech and argue that the theory in its present form is ill-suited to account for de re truths (...) about merely possible entities. I argue that such difficulty is rooted in a problem in the metaphysics of powers. In particular, I contend that the well-known tension between two key principle of powers ontology, namely Directedness and Independence has received an unsatisfactory solution so far, and that it is this unsatisfactory solution concerning the status of “unmanifested manifestations” that makes it hard for Dispositionalism to account for mere possibilia. I develop a novel account of the status of unmanifested manifestations and an overall metaphysics of powers which allows to better respond to Leech's objection and handle mere possibilia. The central idea of the proposal is that unmanifested manifestations are akin to mere logical existents, and are best characterised as non-essentially non-located entities. (shrink)

What grounds facts of ground? Some metaphysicians invoke fundamental grounding laws to answer this question. These are general principles that link grounded facts to their grounds. The main business of this paper is to advance the debate about the metaphysics of grounding laws by exploring the prospects of a plausible yet underexplored minimalist account, one which is structurally analogous to a familiar Humean conception of natural laws. In the positive part of this paper, I articulate such a novel view and (...) argue for its merits. The minimalist account shuns essences and takes laws to be unmysterious elite regularities. Therefore, it is a promising alternative for theorists of ground who spurn the acceptance of essentialism about the grounding laws but think that these are needed in our theorizing. In the negative part, I argue that widely accepted principles of ground, coupled with the tenets of minimalism, jeopardize the fundamentality of the grounding laws. I discuss two immediately available and prima facie appealing strategies to evade this threat. However, I show that both have undesirable theoretical costs. I conclude by casting doubts on whether the benefits of a minimalist account of fundamental grounding laws outweigh such costs. (shrink)

Grounding is claimed to offer a promising characterization of the fundamental as thatwhich is ungrounded. Detractors of this view argue that there can be fundamental and yet mutuallygrounded entities. Such a possibility undermines the denition of the fundamental as theungrounded. I aim to show, however, that the possibility of fundamental mutually grounded entitiesdoes not force us to renounce the prospects of characterizing fundamentality in terms of ground-ing. To accomplish this aim, I defend a grounding-based view that accommodates fundamentalmutually grounded entities (...) straightforwardly. My denition of fundamentality is similar to, butimportantly different from, one that Karen Bennett discusses. I conclude by resisting two objec-tions raised by Jessica Wilson against the Bennettian framework that also target theproposed view. (shrink)

In contemporary metaphysics, the doctrine that the fundamental facts are those which are wholly ungrounded is the received view or something near enough. Against this radical brutalism, several metaphysicians argued in favour of the existence of fundamental facts that are moderately brute or merely partially grounded. However, the arguments for moderately brute facts rely on controversial metaphysical scenarios. This paper aims to counteract the tendency in favour of radical brutalism on scientific grounds. It does so by showing that naturalistic metaphysicians (...) can appeal to plausible considerations from physical theory to establish the existence of moderately brute facts. But should the naturalistic metaphysician embrace moderate brutalism, namely the view that the fundamental facts are those which are merely partially ungrounded? Here I argue for a negative answer, recommending a more inclusive pluralism about the kinds of brute facts we can expect to find in nature. (shrink)

There is a largely unrecognized ambiguity concerning the nature of a trope. Disambiguation throws into relief two fundamentally different conceptions of a trope and provides two ways to understand and develop each metaphysical theory that put tropes to use. In this paper I consider the relative merits that result from differences concerning a trope’s ability to ground the character of ordinary objects. I argue that on each conception of a trope, there are unique implications and challenges concerning character-grounding.

Philosophers have applied the framework of constitutive grounds to make sense of the disagreement between subjectivism and objectivism. The framework understands the two theories as being involved in a disagreement about the extent to which value is determined by attitudes. Although the framework affords us with some useful observations about how this should be interpreted, the question how value can be determined by attitudes in the first place is left largely unanswered. Here we explore the benefits of a positive interpretation (...) which aims to address this oversight and make the framework more informative. This interpretation, which is inspired by the recent work of Schroeder and Sobel, claims that the relevant sense in which value can be determined by attitudes is discovered by seeing how facts can be endowed with the normative property of being a reason. We argue that this interpretation significantly deepens our understanding of the disagreement between subjectivism and objectivism. (shrink)

Within the context of the debate between ontological monists and pluralists the paper discusses a number of argumentative strategies that the latter can apply to answer the “there can be only one” argument. I show here that the reply to this argument suggested by J. Turner has its disadvantages and suggest a number of adjustments thereof. In particular, I develop a concept of domain-specific quantifiers that allow the pluralist to elaborate his or her ontological position.

Contra recent, inflationary views, the paper submits a deflationary approach to legal ontology. It argues, in particular, that to answer ontological questions about legal entities, we only need conceptual analysis and empirical investigation. In developing this proposal, it follows Amie Thomasson’s ‘easy ontology’ and her strategy for answering whether ordinary objects exist. The purpose of this is to advance a theory that, on the one hand, does not fall prey to sceptical views about legal reality (viz., that ontological truths about (...) legal entities are established by metaphysical principles); and, on the other, is compatible with common-sense jurisprudence (viz., that there in fact exist legal entities, and they all have important practical implications). While this methodology is common to legal philosophers interested in elucidating the ‘artifactual nature’ of law, the paper departs from their projects by taking a step forward in connecting this deflationary approach to legal ontology with an expressivist account of legal discourse, thus providing enough resources to satisfy the general ambition of jurisprudence, viz., to establish the conditions for the analysis of legal reality and its normative character.

Many questions about wellbeing involve metaphysical dependence. Does wellbeing depend on minds? Is wellbeing determined by distinct sorts of things? Is it determined differently for different subjects? However, we should distinguish two axes of dependence. First, there are the grounds that generate value. Second, there are the connections between the grounds and value which make it so that those grounds generate that value. Given these distinct axes of dependence, there are distinct dimensions to questions about the dependence of wellbeing. In (...) this paper, I offer a view of wellbeing that gives different answers with respect to these different dimensions. The view is subjectivist about connections but objectivist about grounds. Pluralist about grounds but monist about connections. Invariabilist about connections but variabilist about grounds. Thus, the view offers a simple account that captures the complexity of wellbeing. (shrink)

A central tension shaping metaethical inquiry is that normativity appears to be subjective yet real, where it’s difficult to reconcile these aspects. On the one hand, normativity pertains to our actions and attitudes. On the other, normativity appears to be real in a way that precludes it from being a mere figment of those actions and attitudes. In this paper, I argue that normativity is indeed both subjective and real. I do so by way of treating it as a special (...) sort of artifact, where artifacts are mind-dependent yet nevertheless can carve at the joints of reality. In particular, I argue that the properties of being a reason and being valuable for are grounded in attitudes yet are still absolutely structural. (shrink)

Many philosophers are sceptical about the power of philosophy to refute commonsensical claims. They look at the famous attempts and judge them inconclusive. I prove that, even if those famous attempts are failures, there are alternative successful philosophical proofs against commonsensical claims. After presenting the proofs I briefly comment on their significance.

In her book Fiction and Metaphysics (1999) Amie Thomasson, influenced by the work of Roman Ingarden, develops a phenomenological approach to fictional entities in order to explain how non-fictional entities can be referred to intrafictionally and transfictionally, for example in the context of literary interpretation. As our starting point we take Thomasson’s realist theory of literary fictional objects, according to which such objects actually exist, albeit as abstract and artifactual entities. Thomasson’s approach relies heavily on the notion of ontological dependence, (...) but its precise semantics has not yet been developed. Moreover, the modal approach to the notion of ontological dependence underlying the Artifactual Theory has recently been contested by several scholars. The main aims of this paper are (i) to develop a semantic approach to the notion of ontological dependence in the context of the Artifactual Theory of fiction, and in so doing bridge a number of philosophical and logical gaps; (ii) to generalize Thomasson’s categorial theory of ontological dependence by reconstructing ontological categories of entities purely in terms of different structures of ontological dependence, rather than in terms of the basic kinds of entities the categorical entities depend on.

I apply the notion of truthmaking to the topic of fundamentality by articulating a truthmaker theory of fundamentality according to which some truths are truth-grounded in certain entities while the ones that don't stand in a metaphysical-semantic relation to the truths that do. I motivate this view by critically discussing two problems with Ross Cameron's truthmaker theory of fundamentality. I then defend this view against Theodore Sider's objection that the truthmaking approach to fundamentality violates the purity constraint. Truthmaker theorists can (...) have a trouble-free theory of fundamentality. (shrink)

Truthmaker monism is the view that the one and only truthmaker is the world. Despite its unpopularity, this view has recently received an admirable defence by Schaffer :307–324, 2010b). Its main defect, I argue, is that it omits partial truthmakers. If we omit partial truthmakers, we lose the intimate connection between a truth and its truthmaker. I further argue that the notion of a minimal truthmaker should be the key notion that plays the role of constraining ontology and that truthmaker (...) monism is not necessary for an appropriate solution to the problem of finding truthmakers for negative truths. I conclude that we should reject truthmaker monism once and for all. (shrink)

Priority Theory is an increasingly popular view in metaphysics. By seeing metaphysical questions as primarily concerned with what explains what, instead of merely what exists, it promises not only an interesting approach to traditional metaphysical issues but also the resolution of some outstanding disputes. In a recent paper, Louis deRosset argues that Priority Theory isn’t up to the task: Priority Theory is committed to there being explanations that violate a formal constraint on any adequate explanation. This paper critically examines deRosset’s (...) challenge to Priority Theory. We argue that deRosset’s challenge ultimately fails: his proposed constraint on explanation is neither well-motivated nor a general constraint. Nonetheless, lurking behind his criticism is a deep problem for prominent ways of developing Priority Theory, a problem which we develop. (shrink)

‘Thing’ in the titular question should be construed as having the utmost generality. In the relevant sense, a thing just is an entity, an existent, a being. The present task is to say what a thing of any category is. This task is, I believe, the primary one of any comprehensive and systematic metaphysics. Indeed, an answer provides the means for resolving perennial disputes concerning the integrity of the structure in reality—whether some of the relations among things are necessary merely (...) given those relata themselves—and the intricacy of this structure—whether some things are more or less fundamental than others. After considering some reasons for thinking the generality of the titular question makes it unanswerable, I propound the methodology, original inquiry, required to answer it. The key to this methodology is adopting a singular perspective; confronting the world as merely the impetus to inquiry, one can attain an account of what a thing must be. Radical ontology is a systematic metaphysics—broadly Aristotelian, essentialist and nonhierarchical—that develops the consequences of this account. With it, it is possible to move past stalemate in metaphysics by revealing the grounds of a principled choice between seemingly incommensurable worldviews. (shrink)

Each thing is fundamental. Not only is no thing any more or less real than any other, but no thing is prior to another in any robust ontological sense. Thus, no thing can explain the very existence of another, nor account for how another is what it is. I reach this surprising conclusion by undermining two important positions in contemporary metaphysics: hylomorphism and hierarchical views employing so-called building relations, such as grounding. The paper has three main parts. First, I observe (...) hylomorphism is alleged by its proponents to solve various philosophical problems. However, I demonstrate, in light of a compelling account of explanation, that these problems are actually demands to explain what cannot be but inexplicable. Second, I show how my argument against hylomorphism illuminates an account of the essence of a thing, thereby providing insight into what it is to exist. This indicates what a thing, in the most general sense, must be and a correlative account of the structure in reality. Third, I argue that this account of structure is incompatible not only with hylomorphism, but also with any hierarchical view of reality. Although hylomorphism and the latter views are quite different, representing distinct philosophical traditions, I maintain they share untenable accounts of structure and fundamentality and so should be rejected on the same grounds.
