Social metaphysics is a source of important philosophical and moral insight. Furthermore, much social metaphysics appears to be substantive. However, some have recently argued that standard views of metaphysics cannot accommodate substantive social metaphysics. In this paper I offer a new diagnosis of this problem and defend a new solution, showing that this problem is an illuminating lens through which to examine the nature and boundaries of metaphysics. This case instantiates a broad, common pattern generated by attempts to align distinctions (...) between realism and anti-realism, mind-independence and mind-dependence, and legitimate and non-legitimate inquiry. I show that the best response is to abandon the association between substantive metaphysics and mind-independence, and I sketch a new definition of substantivity, given in terms of explanatory power, that makes room for substantive social metaphysics while also offering an attractive basis for general metaphysics.

The argument from reason states that if naturalism is true, then our beliefs are caused by physical processes rather than being causally based in their reasons, so our beliefs are not knowledge—including the belief in naturalism itself. Recent critics of the argument from reason provide dual process replies to the argument from reason—our beliefs can have both a naturalistic cause/ explanation and be caused/explained by its reasons, thereby showing that naturalism can accommodate knowledge. In this paper I consider three dual (...) process replies and conclude that none of them are successful. (shrink)

In this paper, I consider the relationship between coming to understand why something must be the case and coming to understand why it actually is the case in some particular instance. Peter Lipton uses the possibility of coming to understand a phenomenon via a necessity proof as an argument that there can be understanding with no explanation. Lipton’s argument has come under criticism, at least partially because one might think that understanding why something must be the case has a different (...) object from understanding the actual phenomenon. In this paper, I argue that that under certain circumstances it is fairly straightforward to come to understand an actual phenomenon on the basis of knowing why it had to be the case. Rather than relying on brute intuitions, my primary strategy will be to show that on least some modern accounts of understanding we can validate Lipton’s general point with respect to a variety of possible necessity relations.

There are multiple formal characterizations of the natural numbers available. Despite being inter-derivable, they plausibly codify different possible applications of the naturals – doing basic arithmetic, counting, and ordering – as well as different philosophical conceptions of those numbers: structuralist, cardinal, and ordinal. Nevertheless, some influential philosophers of mathematics have argued for a non-egalitarian attitude according to which one of those characterizations is more “legitmate” in virtue of being “more basic” or “more fundamental”. This paper addresses two related issues. First, (...) we review some of these non-egalitarian arguments, lay out a laundry list of different, legitimate, notions of relative priority, and suggest that these arguments plausibly employ different such notions. Secondly, we argue that given a metaphysical-cum-epistemological gloss suggested by Frege’s foundationalist epistomology, the ordinals are plausibly more basic than the cardinals. This is just one orientation to relative priority one could take, however. Ultimately, we subscribe to an egalitarian attitude towards these formal characterizations: they are, in some sense, equally “legitimate”. (shrink)

Wir Menschen streben danach, die Wirklichkeit zu verstehen. Eine Welt, die wir gut verstehen, ist eine, die wir "im Griff" haben, mit der wir gut umgehen können.

'Chains of Being' argues that there can be infinite chains of dependence or grounding. Cameron also defends the view that there can be circular relations of ontological dependence or grounding, and uses these claims to explore issues in logic and ontology.

Drawing on material from Husserlian phenomenology, we can reconstruct a realist version of anomalous monism (rAM). According to such a view, mental events are identical to some physical events because they simultaneously exemplify mental and physical properties. rAM would have to confront the charge of epiphenomenalism because Husserl rejects psychophysical causal interaction. And as a form of nonreductive physicalism, rAM also faces the challenge of Kim’s supervenience argument and explanatory exclusion. Utilizing Husserl’s conception of mental motivation and contemporary elaborations of (...) substance causation, rAM can refute the accusation of epiphenomenalism and overcome the problem of exclusion.

According to metaphysical coherentism, grounding relations form an interconnected system in which things ground each other and nothing is ungrounded. This potentially viable view’s logical territory remains largely unexplored. In this paper, I describe that territory by articulating four varieties of metaphysical coherentism. I do not argue for any variety in particular. Rather, I aim to show that not all issues which might be raised against coherentism will be equally problematic for all the versions of that view, which features far (...) more nuance and diversity than is typically ascribed to it.

In recent years, several philosophers have argued that their discipline makes no progress (or not enough in comparison to the “hard sciences”). A key argument for this pessimistic position appeals to the purported fact that philosophers widely and systematically disagree on most major philosophical issues. In this paper, we take a step back from the debate about progress in philosophy specifically and consider the general question: How (if at all) would disagreement within a discipline undermine that discipline’s progress? We reject (...) two arguments from disagreement to a lack of progress, and spell out two accounts of progress on which progress is compatible with disagreements that persist or increase over time. However, we also argue that disagreement can undermine our ability to tell which developments are progressive (and to what degree). So, while disagreement can indeed be a threat to progress, the precise nature of the threat has not been appreciated. (shrink)

In this essay, I propose a functionalist theory of grounding (functionalist-grounding). Specifically, I argue that grounding is a second-order phenomenon that is realized by relations that play the noncausal explanatoriness role. I also show that functionalist-grounding can deal with a powerful challenge. Appeals to explanatory unificationism have been made to argue that the success of noncausal explanations does not depend on the existence of grounding relations. Against this, I argue that a systematization involving functionalist-grounding is superior to its anti-relational counterpart.

Ascriptions of truth give rise to an explanatory asymmetry. For instance, we accept ‘ is true because Rex is barking’ but reject ‘Rex is barking because is true’. Benjamin Schnieder and other philosophers have recently proposed a fresh explanation of this asymmetry: they have suggested that the asymmetry has a conceptual rather than a metaphysical source. The main business of this paper is to assess this proposal, both on its own terms and as an option for deflationists. I offer a (...) pair of objections to the proposal and defend them from counter-objections. To conclude, I discuss how else to explain the asymmetry, and set out the implications for deflationism and correspondence theories of truth. (shrink)

Husserl’s early picture of explanation in the sciences has never been completely provided. This lack represents an oversight, which we here redress. In contrast to currently accepted interpretations, we demonstrate that Husserl does not adhere to the much maligned deductive-nomological (DN) model of scientific explanation. Instead, via a close reading of early Husserlian texts, we reveal that he presents a unificationist account of scientific explanation. By doing so, we disclose that Husserl’s philosophy of scientific explanation is no mere anachronism. It (...) is, instead, tenable and relevant. We discuss how Husserl and other contemporary thinkers draw theoretical inspiration from the same source—namely, Bernard Bolzano. Husserl’s theory of scientific explanation shares a common language and discusses the same themes as, for example, Phillip Kitcher and Kit Fine. To advance our novel reading, we discuss Husserl’s investigations of grounding, inter-lawful explanation, intra-mathematical explanation, and scientific unification. (shrink)

El principal problema del panpsiquismo es el problema de la combinación. Como solución se distinguen dos tipos de panpsiquismo: el panpsiquismo constitutivo y el panpsiquismo emergentista. Pero esta distinción opera sobre la distinción entre fundación y causalidad. Sin embargo, se verán razones para considerar que causalidad y fundación no son distintos. De modo que la distinción entre los anteriores panpsiquismos colapsa. Posibilitando la postulación de un nuevo tipo de panpsiquismo, el panpsiquismo de construcción. También, se trazará un primer esbozo de (...) solución para el problema de la combinación desde el punto de vista del panpsiquismo de construcción. (shrink)

Recent years have seen growing interest in modifying interventionist accounts of causal explanation in order to characterise noncausal explanation. However, one surprising element of such accounts is that they have typically jettisoned the core feature of interventionism: interventions. Indeed, the prevailing opinion within the philosophy of science literature suggests that interventions exclusively demarcate causal relationships. This position is so prevalent that, until now, no one has even thought to name it. We call it “intervention puritanism” (I-puritanism, for short). In this (...) paper, we mount the first sustained defence of the idea that there are distinctively noncausal explanations which can be characterized in terms of possible interventions; a position we call “intervention liberalism” (I-liberalism, for short). While many have followed James Woodward (2003) in committing to I-puritanism, we trace support for I-liberalism back to the work of Jaegwon Kim (1974). Furthermore, we analyse two recent sources of scepticism regarding I-liberalism: debate surrounding mechanistic constitution; and attempts to provide a monistic account of explanation. We show that neither literature provides compelling reasons for adopting I-puritanism. Finally, we present a novel taxonomy of available positions upon the role of possible interventions in explanation: weak causal imperialism; strong causal imperialism; monist intervention puritanism; pluralist intervention puritanism; monist intervention liberalism; and finally, the specific position defended in this paper, pluralist intervention liberalism.

Separatists about grounding take explanations to be separate from their corresponding grounding-facts. Grounding-facts are supposed to underlie, or back, such explanations. However, the backing relation hasn’t received much attention in the literature. The aim of this paper is to provide an informative definition of backing. First, I examine two prominent proposals: backing as explaining (Kovacs 2017; 2019a) and backing as grounding (see Sjölin Wirling 2020). Finally, I put forward my own proposal. I argue that under plausible assumptions about the role (...) of backing and the nature of explanation, backing should be understood as a form of truthmaking, minimally construed. (shrink)

A traditional account of coincidences has it that two facts are coincidental whenever they are not related as cause and effect and do not have a common cause. A recent contribution by Lando : 132–151, 2017) showed that this account is mistaken. In this paper, I argue against two alternative accounts of coincidences, one suggested by Lando, and another by Bhogal : 677–694, 2020), and defend a third one in their place. In short, I propose that how explanatory links relate (...) to non-coincidental facts in explanation is what drives a wedge between coincidences and non-coincidences. This proposal is not susceptible to the worries I raise, and is more general, since it is not restricted to coincidences and non-coincidences involving physical facts. (shrink)

Neil Levy mounts two arguments against Robert Kane’s influential libertarian theory. According to the first, because Kanean self-forming actions are undetermined, there can be no contrastive explanation for why agents choose as they do rather than otherwise, in which case how they choose appears to be a matter of luck. According to the second, if one grants Kane the claim that agents are responsible for their undetermined choices in virtue of the fact that they made efforts of will to choose (...) them, the fact that agents engage in dual efforts of will leads to an implausible doubling of the agent’s responsibility. We defend Kane from both objections. We argue against the first by clarifying the nature of contrastive explanation in the context of Kane’s theory and we argue against the second by showing that the kind of doubling of responsibility implied by an agent’s dual efforts of will is, in fact, innocuous.

This paper explores a novel notion of self-explanation that combines ideas from two sources: the tripartite account of explanation, according to which a proposition can help explain another either in the capacity of a reason why the latter obtains or in the capacity of an explanatory link, and the notion of an empty-base explanation, which generalizes the ideas of explanation by zero-grounding and explanation by status. After having introduced these ideas and the novel notion of self-explanation, I argue that the (...) latter has the potential to resist extant arguments against the possibility of self-explanation. In the remainder of the paper, I discuss candidates for such self-explanatory propositions and suggest possible applications for Humeanism about laws of nature, the debate on the grounds of ground, the rationalist tradition, and philosophical theology.

The recent holistic trends in metaphysics are surveyed here and a tentative typology is offered. The non-linear mode of composition is suggested as the key feature of holism, apart from its familiar non-reductionism and emergentism. It is argued that those holistic views are promising that refrain from extreme relationalism based on the denial of there being self-subsistence particulars; also, those refraining from the postulation of an unarticulated all-embracing whole where both relations and terms are denied to be genuine ontological items. (...) The further suggestion is that a trade-off between the holistic perspective and the limits imposed upon it in the form of built-in confinements may help in making this metaphysics go. (shrink)

Explanatory realism is the view that explanations work by providing information about relations of productive determination such as causation or grounding. The view has gained considerable popularity in the last decades, especially in the context of metaphysical debates about non-causal explanation. What makes the view particularly attractive is that it fits nicely with the idea that not all explanations are causal whilst avoiding an implausible pluralism about explanation. Another attractive feature of the view is that it allows explanation to be (...) a partially epistemic, context-dependent phenomenon. In spite of its attractiveness, explanatory realism has recently been subject to criticism. In particular, Taylor :197–219, 2018). has presented four types of explanation that the view allegedly cannot account for. This paper defends explanatory realism against Taylor’s challenges. We will show that Taylor’s counterexamples are either explanations that turn out to provide information about entities standing in productive determination relations or that they are not genuine explanations in the first place.

Starting with the slogan that understanding is a ‘knowledge of causes’, Stephen Grimm and John Greco have argued that understanding comes from a knowledge of dependence relations. Grounding is the trendiest dependence relation on the market, and if Grimm and Greco are correct, then instances of grounding should also give rise to understanding. In this paper, I will show that this prediction is correct – grounding does indeed generate understanding in just the way that Grimm and Greco anticipate. However, grounding (...) examples of understanding also show that Grimm and Greco are not telling the full story when it comes to understanding. Understanding can only be generated by a particular subset of dependence relations – those dependence relations that are also explanatory. Grimm and Greco should thus appeal to a privileged class of dependence relations, relations like grounding that can also give rise to explanation. (shrink)

Many philosophers think there is a luck problem confronting libertarian models of free will. If free actions are undetermined, then it seems to be a matter of chance or luck that they occur—so the objection goes. Agent-causal libertarians have responded to this objection by asserting that free actions, in their essence, involve a direct causal relation between agents and the events they cause. So, free actions are not lucky after all. Not everyone, however, is convinced by this response. Al Mele (...) and Peter van Inwagen, for instance, argue that luckiness remains even if agent-causation exists. One way to answer their arguments, I suggest, is by appealing to considerations in metaphysical grounding and the associated idea of explanatory priority. Mele’s argument loses force if facts about which possible world is actual are partly grounded in facts about free choices themselves. And van Inwagen’s challenge can be met if facts about free actions are explanatorily prior to any objective probabilities associated with those actions. (shrink)

Traditional rationalist approaches to a priori epistemology have long been looked upon with suspicion for positing a faculty of rational intuition capable of knowing truths about the world apart from experience. Conceptualists have tried to fill this void with something more empirically tractable, arguing that we know a priori truths due to our understanding of concepts. All of this theorizing, however, has carried on while neglecting an entire cross section of such truths, the grounding claims that we know a priori. (...) Taking a priori grounding into account poses a significant challenge to conceptualist accounts of a priori knowledge, as it is unclear how merely understanding conceptual connections can account for knowledge of grounding. The fact that we do know some grounding truths a priori, then, is a significant mark in traditional rationalism’s favor, and the next frontier for those who aim to eliminate the mystery surrounding a priori knowledge.

A lot of philosophical energy has been devoted recently in trying to determine if mathematics can contribute to our understanding of physical phenomena. Not many philosophers are interested, though, if the converse makes sense, i.e., if our cognitive interaction (scientific or otherwise) with the physical world can be helpful (in an explanatory or non-explanatory way) in our efforts to make sense of mathematical facts. My aim in this paper is to try to fill this important lacuna in the recent literature. (...) My answer to the question of this paper is negative. As I will argue, there are serious problems with the main reasons for believing in the first place that it is possible to have physical understanding of mathematical facts. (shrink)

There is, among philosophers involved in the debate concerning the nature and epistemology of understanding, a general recognition that this state has a grasping component that accounts for some of its distinctive features. This paper defends the view that this component of understanding consists of a knowledge of how to use a particular explanation to account for a given phenomenon. The way in which a subject acquires this knowledge is examined and the result of this examination is shown to highlight (...) the particular contribution of the grasping component of understanding to the distinctive features of this state.

How is grounding related to metaphysical explanation? The standard view is that the former somehow “backs”, “undergirds” or “underlies” the latter. This view fits into a general picture of explanation, according to which explanations in general hold in virtue of a certain elite group of “explanatory relations” or “determinative relations” that back them. This paper turns the standard view on its head: grounding doesn't “back” metaphysical explanation but is in an important sense downstream from it. I call this view “grounding (...) idealism”, since it structurally resembles an analogous view about causation that is known as “causal idealism” and has been endorsed by philosophers like Michael Scriven and Philip Kitcher. I formulate a specific version of grounding idealism, Metaphysical Explanation‐First Idealism (MEFI), according to which the semantic value of ‘grounding’ is an abundant, gerrymandered relation settled by the metaphysical explanation facts. Then I offer some theoretical considerations that support MEFI over rival accounts of the relation between grounding and metaphysical explanation. Finally, I address the question of what role is left for grounding to play, if not that of “backing” metaphysical explanations. (shrink)

Several have denied that there is, specifically, a criterion of identity for persons and some deny that there are, for any kind, diachronic criteria of identity. I argue, however, that there are no criteria of identity, either synchronic or diachronic, for any kind whatsoever. I begin by elaborating the notion of a criterion of identity in order to clarify what exactly is being denied when I maintain there are none. I examine the motivation of those who qualify in some way (...) the general claim that there are synchronic and diachronic criteria of identity for every kind, then present my direct and categorical argument against such criteria. I next evaluate the objections of those who argue that rejecting criteria of identity has untenable results. These objections are ineffective, each based on the incorrect assumption that if there is no criterion of identity for a kind, the identity of an instance of that kind is independent of its qualities. I conclude by considering some of the upshots of rejecting criteria of identity and the insight doing so provides into things in general and the limits of ontological inquiry. (shrink)

The primitive ontology approach to quantum mechanics seeks to account for quantum phenomena in terms of a distribution of matter in three-dimensional space and a law of nature that describes its temporal development. This approach to explaining quantum phenomena is compatible with either a Humean or powerist account of laws. In this paper, I offer a powerist ontology in which the law is specified by Bohmian mechanics for a global configuration of particles. Unlike in other powerist ontologies, however, this law (...) is not grounded in a structural power that is instantiated by the global configuration. Instead, I combine the primitive ontology approach with Aristotle’s doctrine of hylomorphism to create a new metaphysical model, in which the cosmos is a hylomorphic substance with an intrinsic power to choreograph the trajectories of the particles.

In this paper I propose a notion of propria inspired by Aristotle, on which propria are non-essential, necessary properties explained by the essence of a thing. My proposal differs from the characterization of propria by Kit Fine and Kathrin Koslicki: unlike Fine, the relation of explanation on my account can’t be assimilated to a notion of logical entailment. In disagreement with Koslicki, I suggest that the explanatory relation at issue needs not be necessary. My account of essence is conceptually parsimonious: (...) it illuminates the contribution of essence to explanation without relying on obscure notions such as Aristotelian form or identity. (shrink)

Humeans are often accused of positing laws which fail to explain or are involved in explanatory circularity. Here, I will argue that these arguments are confused, but not because of anything to do with Humeanism: rather, they rest on false assumptions about causal explanation. I’ll show how these arguments can be neatly sidestepped if one takes on two plausible commitments which are motivated independently of Humeanism: first, that laws don’t directly feature in scientific explanation and second, the view that explanation (...) is contrastive. After outlining and motivating these views, I show how they bear on explanation-based arguments against Humeanism. (shrink)

Since K. Fine’s influential criticism of modalism, many philosophers have agreed that we cannot understand the concept of essence with that of modality. However, some philosophers have resisted this mainstream position. In this paper, I examine N. Wildman’s claim that, unlike other versions of modalism, his version of modalism, namely Sparse Modalism can save modalism. I will argue first that if we introduce the notion of grounding into this debates, Wildman’s criticisms of other versions are significantly undermined. Next, I will (...) argue that since Sparse Modalism has an implicit commitment to grounding Wildman cannot blame revising other versions modalism with the concept of grounding. From these claims, I will conclude that the prospect of the success of modalism in general is at best dubious. Without the concept of grounding no version of modalism can succeed and with the concept of grounding no version is well motivated. (shrink)

This paper is a response to McKenzie (2017). I argue that the case she presents is not a genuine counterexample to the thesis she labels Brute Fundamentalism. My response consists of two main points. First, that the support she presents for considering her case a metaphysical explanation is misguided. Second, that there are principled reasons for doubting that partial explanations in Hempel’s sense, of which her case is an instance, are genuinely explanatory in the first place. Thus McKenzie’s attack on (...) Brute Fundamentalism fails. (shrink)

En utilisant le cadre théorique développé par Jaegwon Kim, soit l’opposition entre le réalisme explicatif et l’irréalisme explicatif, ainsi que quelques observations sur la métaphysique et l’épistémologie de l’explication, je réexamine le désaccord opposant Robert Kane à Richard Double au sujet du principe de l’explication rationnelle. Je défends la position de Kane sur la double rationalité et je soutiens que le principe proposé par Double possède un champ d’application plus limité qu’il le prétend. Je montre aussi que, contrairement à ce (...) que suppose Double, la façon dont Kane entend expliquer l’action ne se transforme pas en une forme d’irréalisme explicatif. (shrink)

Dans deux articles récents, Jaegwon Kim aborde le problème de l’explication de l’action d’une façon qui est centrée sur l’agent et fondée sur les raisons. Je soutiens que, bien qu’il prétende le contraire, la proposition de Kim ouvre la voie à une vision pluraliste de l’explication qui pourrait résoudre le problème de l’exclusion explicative et fournir un moyen permettant au physicalisme non réductionniste de se soustraire à l’argument de la survenance, aussi appelé argument de l’exclusion.

Philosophical accounts of scientific explanation are broadly divided into ontic and epistemic views. This paper explores the idea that the lexical ambiguity of the verb to explain and its nominalisation supports an ontic conception of explanation (Salmon 1989; Craver 2007). I analyse one argument which challenges this strategy by criticising the claim that explanatory talk is lexically ambiguous (Wright, European Journal of Philosophy of Science 2(3), 375–394, 2012). I propose that the linguistic mechanism of transfer of meaning (Nunberg, Journal of (...) Semantics 12(2), 109–132, 1995) provides a better account of the lexical alternations that figure in the systematic polysemy of explanatory talk, and evaluate the implications of this proposal for the debate between ontic and epistemic conceptions of scientific explanation.

For any normative domain, we can theorize about what is good in that domain. Such theories include utilitarianism, a view about what is good morally. But there are many domains other than the moral; these include the prudential, the aesthetic, and the intellectual or epistemic. In this last domain, it is good to be knowledgeable and bad to ignore evidence, quite apart from the morality, prudence, and aesthetics of these things. This dissertation builds a theory that stands to the epistemic (...) domain as utilitarianism stands to the moral domain. It builds an epistemic value theory. (shrink)

For three decades the writings of Jaegwon Kim have had a major influence in philosophy of mind and in metaphysics. Sixteen of his philosophical papers, together with several new postscripts, are collected in Kim [1993]. The publication of this collection prompts the present essay. After some preliminary remarks in the opening section, in Section 2 I will briefly describe Kim's philosophical 'big picture' about the relation between the mental and the physical. In Section 3 I will situate Kim's approach on (...) the larger philosophical landscape, vis-à-vis various other approaches frequently discussed in contemporary philosophy of mind. This comparative discussion will further illuminate Kim's own position, and also will serve as groundwork for subsequent discussion. In Section 4 I will point out certain persistent internal tensions in Kim's philosophical position on the mind--body problem, tensions that emerge especially clearly against the backdrop of Section 3's comparative discussion of Kim's position relative to various competing positions. In the remainder of the paper I will focus on two issues at the heart of his position, with particular attention to what he says about them in some of the more recent papers and the postscripts in Kim [1993]. First, how should a materialist understand the notion that the mental is 'determined' by the physical? More specifically, what role, if any, should be played by the concept of supervenience in explicating this kind of determination relation? Kim's views on this matter have recently changed, and I will discuss the issue with particular attention to his own latest remarks on it. This is the business of Section 5. Second, need a viable materialism assert that mentalistic psychology is reducible to neurobiology (and ultimately to physics)? More specifically, should a materialist insist on reducibility, despite the currently influential line of argument used by non-reductive materialists, the 'multiple realization' argument? On this matter too, Kim's views have changed somewhat; again, I will discuss the issue with particular attention to his recent thinking. This is the business of Section 6. (shrink)

Since the late 1980’s Kim has presented some major reasons to abandon SC. In MIAPW at least four of these reasons are offered: under SC we lose mental causation, mental realism and psychological explanations. Moreover, supervenience cannot do the job as the cementing relation in SC.
