Discussion of a metaphysical sense of 'inheritance' and cognate notions relevant to fundamentality.

This edited collection provides new perspectives on some metaphysical questions arising in quantum mechanics. These questions have been long-standing and are of continued interest to researchers and graduate students working in physics, philosophy of physics and metaphysics. It features contributions from a diverse set of researchers, ranging from senior scholars to junior academics, working in varied fields, from physics to philosophy of physics and metaphysics. The contributors reflect on issues about fundamentality (is quantum theory fundamental? If so, what is (...) its fundamental ontology?), ontological dependence (how do ordinary objects exist even if they are not fundamental?), realism (what kind of realism is compatible with quantum theory?), indeterminacy (can the world itself exhibit ontological indeterminacy?). With contributions from both physicists (including Nobel Prize winner Gerard 't Hooft), science communicators and philosophers. (shrink)

I introduce a proof system for the logic of relative fundamentality, as well as a natural semantics with respect to which the system is both sound and complete. I then “modalise” the logic, and finally I discuss the properties of grounding given a suggested account of this notion in terms of necessity and relative fundamentality.

I defend a new account of constitutive essence on which an entity’s constitutively essential properties are its most fundamental, nontrivial necessary properties. I argue that this account accommodates the Finean counterexamples to classic modalism about essence, provides an independently plausible account of constitutive essence, and does not run into clear counterexamples. I conclude that this theory provides a promising way forward for attempts to produce an adequate nonprimitivist, modalist account of essence. As both triviality and fundamentality in the account (...) are understood in terms of grounding, the theory also potentially has important implications for the relation between essence and grounding.

I describe a number of views in which metaphysical fundamentality is accounted for in normative terms. After describing many different ways this key idea could be developed, I turn to developing the idea in one specific way. After all, the more detailed the proposal, the easier it is to assess whether it works. The rough idea is that what it is for a property to be fundamental is for it to be prima facie obligatory to theorize in terms of (...) that property. (shrink)

It can seem incoherent to fully characterize fundamentality in terms of grounding, given that the fundamental is precisely that which cannot be fully characterized independently. I argue that there is no such incoherence.

Substance and the Fundamentality of the Familiar explicates and defends a novel neo-Aristotelian account of the structure of material objects. While there have been numerous treatments of properties, laws, causation, and modality in the neo-Aristotelian metaphysics literature, this book is one of the first full-length treatments of wholes and their parts. Another aim of the book is to further develop the newly revived area concerning the question of fundamental mereology, the question of whether wholes are metaphysically prior to their (...) parts or vice versa. Inman develops a fundamental mereology with a grounding-based conception of the structure and unity of substances at its core, what he calls substantial priority, one that distinctively allows for the fundamentality of ordinary, medium-sized composite objects. He offers both empirical and philosophical considerations against the view that the parts of every composite object are metaphysically prior, in particular the view that ascribes ontological pride of place to the smallest microphysical parts of composite objects, which currently dominates debates in metaphysics, philosophy of science, and philosophy of mind. Ultimately, he demonstrates that substantial priority is well-motivated in virtue of its offering a unified solution to a host of metaphysical problems involving material objects. (shrink)

Consider the idea that some entities are more fundamental than others, some entities ‘ground’ other, less fundamental, entities. What is it for something to be more fundamental than another, or for something to ‘ground’ something else? This paper urges the rejection of conceptions of grounding and fundamentality according to which reality has a hierarchical structure in which higher-level entities are taken to be distinct from but metaphysically dependent on more fundamental lower-level entities. Truthmaking is offered as an apt replacement (...) for at least some of the many applications of grounding. (shrink)

I argue that dependence is neither necessary nor sufficient for relative fundamentality. I then introduce the notion of 'likeness in nature' and provide an account of relative fundamentality in terms of it and the notion of dependence. Finally, I discuss some puzzles that arise in Aristotle's Categories, to which the theory developed is applied.

In the recent literature on all things metaontological, discussion of a notorious Meinongian doctrine—the thesis that some objects have no kind of being at all—has been conspicuous by its absence. And this is despite the fact that this thesis is the central element of the noneist metaphysics of Richard Routley (1980) and Graham Priest (2005). In this paper, we therefore examine the metaontological foundations of noneism, with a view to seeing exactly how the noneist's approach to ontological inquiry differs from (...) the orthodox Quinean one. We proceed by arguing that the core anti-Quinean element in noneism has routinely been misidentified: rather than concerning Quine's thesis that to be is to be the value of a variable, the real difference is that the noneist rejects what we identify as Quine's “translate-and-deflate” methodology. In rejecting this aspect of Quinean orthodoxy, the noneist is in good company: many of those who think that questions of fundamentality should be the proper focus of ontological inquiry can be read as rejecting it too. Accordingly, we then examine the differences between the noneist's conception of ontology and that offered by the fundamentalist. We argue that these two anti-Quinean approaches differ in terms of their respective conceptions of the theoretical role associated with the notion of being. And the contrast that emerges between them is, in the end, an explanatory one. (shrink)

In this paper, I argue for a new way of characterizing ontological emergence. I appeal to recent discussions in meta-ontology regarding fundamentality and dependence, and show how emergence can be simply and straightforwardly characterized using these notions. I then argue that many of the standard problems for emergence do not apply to this account: given a clearly specified meta-ontological background, emergence becomes much easier to explicate. If my arguments are successful, they show both a helpful way of thinking about (...) emergence and the potential utility of discussions in meta-ontology when applied to first-order metaphysics.

There is debate as to whether quantum field theory is, at bottom, a quantum theory of fields or particles. One can take a field approach to the theory, using wave functionals over field configurations, or a particle approach, using wave functions over particle configurations. This article argues for a field approach, presenting three advantages over a particle approach: particle wave functions are not available for photons, a classical field model of the electron gives a superior account of both spin and (...) self-interaction as compared to a classical particle model, and the space of field wave functionals appears to be larger than the space of particle wave functions. The article also describes two important tasks facing proponents of a field approach: legitimize or excise the use of Grassmann numbers for fermionic field values and in wave functional amplitudes, and describe how quantum fields give rise to particle-like behavior.

Amijee ("Inquiry and Metaphysical Rationalism") argues that as long as we have not yet discovered that any fact is ungrounded, we ought to be committed to a version of the principle of sufficient reason (PSR), according to which every fact is grounded. In this note I present Amijee’s argument, rebut it, and diagnose where it fails. In a nutshell, the issue with Amijee's argument is that in general, rationally searching for something/seeking something/trying to achieve something does not require believing that (...) one is able to reach one's goal.

Priority monism is roughly the view that the universe is the only fundamental object, that is, a concrete object that does not depend on any other concrete object. Schaffer, the main advocate of PM, claims that PM is compatible with dependence having two different directions: from parts to wholes for subcosmic wholes, and from whole to parts for the cosmic whole. Recently it has been argued that this position is untenable. Given plausible assumptions about dependence, PM entails that dependence has (...) only one direction, it always goes from wholes to parts. One such plausible assumption is a principle of Isolation. I argue that, given all extant accounts of dependence on the market, PM entails No Isolation. The argument depends upon a particular feature of the dependence relation, namely, necessitation and its direction. In the light of this, I contend that the argument is important, insofar as it suggests that we should distinguish dependence from other cognate notions, e.g. grounding. Once this distinction is made, I suggest we should also distinguish between two different notions of fundamentality that might turn out to be not-coextensive. (shrink)

This book argues that our current best theories of fundamental physics are best interpreted as positing spacetime as non-fundamental. It is written in accessible language and largely avoids mathematical technicalities by instead focusing on the key metaphysical and foundational lessons for the fundamentality of spacetime. -/- According to orthodoxy, spacetime and spatiotemporal properties are regarded as fundamental structures of our world. Spacetime fundamentalism, however, faces challenges from speculative theories of quantum gravity – roughly speaking, the project of applying the (...) lessons of quantum mechanics to gravitation and spacetime. This book demonstrates that the non-fundamentality of spacetime does not rely on speculative physics alone. Rather, one can give an interpretation of general relativity that supports some form of spacetime non-fundamentalism. The author makes the case for spacetime non-fundamentalism in three steps. First, he confronts the standard geometrical interpretation of general relativity with Brown and Pooley’s dynamical approach to relativity theory. Second, he considers an alternative derivation of the Einstein field equations, namely the classical spin-2 approach, and argues that it paves the way for a refined dynamical approach to general relativity. Finally, he argues that particle physics can serve as a continuity condition for the metaphysics of spacetime. -/- The Non-Fundamentality of Spacetime will be of interest to scholars and advanced students working in philosophy of physics, philosophy of science, and metaphysics.

Russell is often taken as a forerunner of the Quinean position that “to be is to be the value of a bound variable”, whereupon the ontological commitment of a theory is given by what it quantifies over. Among other reasons, Russell was among the first to suggest that all existence statements should be analyzed by means of existential quantification. That there was more to Russell’s metaphysics than what existential quantifications come out as true is obvious in the earlier period where (...) Russell still made a distinction between existence and being/subsistence. But even the later Russell, including that of the Logical Atomism lectures period, would not have understood ontological questions to be first and foremost questions of quantification. He would take fundamentality to be important too, which explains in part his assertions to the effect the the values of individual variables have a reality not attributable to values of higher-order variables, even ineliminable higher-order variables.

The past decade and a half has seen an absolute explosion of literature discussing the structure of reality. One particular focus here has been on the fundamental. However, while there has been extensive discussion, numerous fundamental questions about fundamentality have not been touched upon. In this chapter, I focus on one such lacuna about the modal strength of fundamentality. More specifically, I am interested in exploring the contingent fundamentality thesis - that is, the idea that the fundamentalia (...) are only contingently fundamental (or, in property-terms, that the property of being fundamental is not a (weakly) necessary property). And while I think this thesis is plausible – indeed, I show here that it lurks in the unexamined shadows/assumptions of some fairly prominent positions – as far as I can tell, nothing has been said either for or against it. Here, I hope to fix this by giving the thesis a proper airing. In this way, this chapter represents a first-pass at exploring not only the modal status of fundamentality, but also offers a starting point for examining broader issues about the relationship between fundamentality and modality.

Are space and time fundamental features of our world or might they emerge from something else? The Foundation of Reality brings together metaphysicians and philosophers of physics working on space, time, and fundamentality to address this timely question.

The view that it is symmetries, not particles, that are fundamental to nature is frequently expressed by physicists. But comparatively little has been written either on what this claim means or whether it should be regarded as true. After placing the claim into a general fundamentality framework, I consider whether the priority of symmetries over particles can be defended. The conclusions drawn are largely negative.

The aim of this work is to apply information theoretic ideas to the notion of fundamentality. I will argue that if one adopts pancomputationalism as a metaphysics for the universe, then there are higher-level structures which are just as fundamental for computation as anything from microphysics.

This paper aims to open up discussion on the relationship between fundamentality and naturalism, and in particular on the question of whether fundamentality may be denied on naturalistic grounds. A historico-inductive argument for an anti-fundamentalist conclusion, prominent within contemporary metaphysical literature, is examined; finding it wanting, an alternative ‘internal’ strategy is proposed. By means of an example from the history of modern physics - namely S-matrix theory - it is demonstrated that this strategy can generate similar anti-fundamentalist conclusions (...) on more defensible naturalistic grounds, and that fundamentality questions can be empirical questions. Some implications and limitations of the proposed approach are discussed. (shrink)

Abstract‘Space does not exist fundamentally: it emerges from a more fundamental non-spatial structure.’ This intriguing claim appears in various research programs in contemporary physics. Philosophers of physics tend to believe that this claim entails either that spacetime does not exist, or that it is derivatively real. In this article, I introduce and defend a third metaphysical interpretation of the claim: reductionism about space. I argue that, as a result, there is no need to subscribe to fundamentality, layers of reality (...) and emergence in order to analyse the constitution of space by non-spatial entities. It follows that space constitution, if borne out, does not provide empirical evidence in favour of a stratified, Aristotelian in spirit, metaphysics. The view will be described in relation to two particular research programs in contemporary physics: wave function realism and loop quantum gravity. (shrink)

I offer an account of fundamentality for facts in terms of metaphysical grounding. The account does justice to the idea that whether a fact is absolutely fundamental, and whether a fact is more fundamental than, or as fundamental as, another fact, are a matter of where in a grounding-induced hierarchy of kinds of facts these facts appear.

Reality is hierarchically structured, or so proponents of the metaphysical posit of grounding argue. The less fundamental facts obtain in virtue of, or are grounded in, the more fundamental facts. But what exactly is it for one fact to be more fundamental than another? The aim of this paper is to provide a measure of relative fundamentality. I develop and defend an account of the metaphysical hierarchy that assigns to each fact a set of ordinals representing the levels on (...) which it occurs. The account allows one to compare any two facts with respect to their fundamentality and it uses immediate grounding as its sole primitive. In the first section, I will set the stage and point to some shortcomings of a rival account proposed by Karen Bennett. The second section will present my own proposal and the third section will discuss how it can be extended to non-foundationalist settings. The fourth section discusses potential objections. (shrink)

I discuss Bennett's characterization of the "more fundamental than" relation.

Fabrice Correia has recently provided reason to think that transcendent entities—entities that are grounded but have no immediate grounds—may exist. I point out that, if they do, grounding fails to have a more general property; it is not accessible, i.e., it is not the case that if x grounds y, there is a chain of finitely many steps of immediate grounding between x and y. I then show that the possibility that grounding is not accessible has two important consequences. First, (...) it provides a reason to prefer one of the two standard ways that grounding has been axiomatized in the literature to the other. Second, there would be cases for which Correia’s and Jonas Werner’s recent definitions of relative fundamentality in terms of grounding do not provide satisfactory measures. I develop an alternative definition that yields more satisfying results in these cases. (shrink)

.In her Making Things Up, amongst the many other achievements of the volume, Bennett develops a rich account of relative fundamentality. She also defends a kind of deflationism about the notion: relative fundamentality is nothing over and above patterns of building. In this essay, I argue that the best and common competitor of this view – primitivism about relative fundamentality – is in worse shape than Bennett's evaluation would indicate. Deflationism looks to be the best view.

Since the early 21st century, processualist approaches have gained prominence in analytic metaphysics and the philosophy of science, prompting diverse responses from advocates of substantialism. However, the polarization of the debate between process and substance metaphysics has often led to oversimplifications that obscure the potential for constructive dialogue. This paper argues that these frameworks should not be treated as monolithic systems, but rather analyzed through the lens of specific metaphysical problems—namely, fundamentality, persistence, and individuation. Focusing primarily on process metaphysics, (...) we examine how different interpretations within both traditions conceptualize these issues. Our analysis reveals areas of compatibility as well as points of divergence, indicating that the divide between processualism and substantialism is more nuanced than commonly assumed. We conclude by advocating for a metaphysical approach that allows for the integration of criteria from both frameworks. (shrink)

1. Categories and the Scientific Turn of Metaphysics: The Notion of World-Fundamentality What are the fundamental inhabitants of the world? This question, as old as it is new, is about the fundamental structure of our world. Is our world a world of Aristotle's ordinary substances, Locke's physical substances, Husserl's wholes, Wittgenstein's facts, Sellars's processes, or Quine's sets? In order to distinguish the sort of metaphysical fundamentality at stake in this discussion from other possible types of fundamentality, I (...) shall call it from now on "world-fundamentality." In this article I want to make a proposal in the context of this metaphysical dispute. The proposal is the addition of a new criterion of world-fundamentality to the existing catalog of independence and simplicity, among some other prominent classical examples. I call this criterion "the materialist criterion of world-fundamentality" because it states that metaphysicians should not decide the question of whether our world is a world of facts rather than a world of sets or other categories without considering the explanatory power of such categories to account for the relation between "the manifest image" and "the scientific image," to use the words of Wilfrid Sellars.

Aristotle speaks of the fundamental as what is ungrounded or, in his own terminology, separate; and he also speaks of the fundamental as what grounds all else, or as what is absolutely prior. Karen Bennett notes that these two notions of fundamentality are extensionally equivalent, provided grounding is well-founded and transitive. Does Aristotle view separation and priority as extensionally equivalent? That is a difficult question to answer, in part because there are a variety of grounding relations in Aristotle, and (...) in many cases, he does not tell us enough about the relation to know if it has the requisite features of being well-founded and transitive. The chapter considers a case study in order to establish a restricted version of the equivalence claim. (shrink)

What justifies the allocation of funding to research in physics when many would argue research in the life and social sciences may have more immediate impact in transforming our world for the better? Many of the justifications for such spending depend on the claim that physics enjoys a kind of special status vis-a-vis the other sciences, that physics or at least some branches of physics exhibit a form of fundamentality. The goal of this paper is to articulate a conception (...) of fundamentality that can support such justifications. I argue that traditional conceptions of fundamentality in terms of dynamical or ontic completeness rest on mistaken assumptions about the nature and scope of physical explanations. (shrink)

This chapter explores a path from the premise that something is fundamental to the premise that something is perfect (in a certain sense to be defined). I begin by identifying a “fundamentality” puzzle, which challenges us to explain how anything could be fundamental. To unpack the puzzle, I consider a series of potential solutions that, for various reasons, only push the explanatory question deeper in. Then I present an account of fundamentality in terms of a purely perfect fundamental (...) nature, and I show how this account has an explanatory advantage over others. Finally, I consider some objections that help draw out the implications of my account of fundamentality. (shrink)

In the recent metaphysics literature, a number of philosophers have independently endeavoured to marry sparse ontology to abundant truth. The aim is to keep ontological commitments minimal, whilst allowing true sentences to quantify over a vastly greater range of entities than those which they are ontologically committed to. For example, an ontological commitment only to concrete, microscopic simples might be conjoined with a commitment to truths such as ‘There are twenty people working in this building’ and ‘There are prime numbers (...) greater than 5.’ I argue that a significant challenge to this project comes from the philosophy of mind. As Theodore Sider has pointed out, anti-physicalism is consistent with a sparse ontology. However, I will try to show that the premises of the standard anti-physicalist arguments can be used to form an argument to the conclusion that sentences which quantify over subjects of experience ontologically commit us to subjects of experience. Truths about consciousness cannot be bought more cheaply than their superficial grammar suggests. (shrink)

Ontic structural realism (OSR) is the view that (i) in spite of the discontinuities that characterise the historical development of science, we can be realist about something, i.e., the concrete counterpart of certain theoretical structures that remain preserved across theory-change; and (ii) such structure is all there is in the actual world, at least at the fundamental level. It is thus a thesis about the fundamental—one whereby relations, not objects, are the basic building blocks of reality. However, there are in (...) fact several dimensions to the structuralism-fundamentality link, and many alternative ways of cashing out the idea that reality is fundamentally structural. Arguably, these require a more systematic and detailed assessment than acknowledged in the literature so far. The chapter provides such an assessment based on considerations coming from both physics and analytic metaphysics, and concludes by pointing to a hitherto quite neglected theoretical option.

Is everything about reality either qualitative or somehow determined by the qualitative character of reality itself? Metaphysical anti-Haecceitism is often taken to be the claim that this is the case, and to entail that reality is fundamentally qualitative. In this paper, I (1) argue against the idea that metaphysical anti-Haecceitism should be characterized in such terms, and (2) defend a novel way to phrase such a view. This will be done by taking the main arguments for anti-Haecceitism as a guide (...) and by singling out the proper commitments of a view that satisfies the desideratum set forth by such arguments. The phrasing I shall offer will help tell the issue of anti-Haecceitism apart from some concerns about fundamentality that, I will contend, are orthogonal to it—among them, the question whether there is fundamentality at all. (shrink)

I argue for a conception of essence that does not rely on distinctions of metaphysical fundamentality.

According to High-Dimensional Wavefunction Fundamentalism (HDWF) the wavefunction field evolving in configuration space is all that exists fundamentally. The main argument in favor of HDWF is an argument from separability and locality: separability is a desirable feature of a fundamental metaphysics and HDWF is indeed such a separable metaphysics. Separability in turn is desirable because it is simple and intuitive. Tim Maudlin has recently argued that intuitiveness and simplicity cannot motivate separability. In particular, our intuitions stem from our interactions with (...) the three-dimensional world which is non-separable. Therefore, he concludes, there is _nothing else_ HDWF theorists can appeal to motivate separability. I call this Maudlin’s challenge. The present paper addresses Maudlin’s challenge by showing how the facts that some plurality of entities are separable entail that its constituents are fundamental, for well-motivated notions of fundamentality.

This article aims to show that fundamentality is construed differently in the two most prominent strategies of analysis we find in physical science and engineering today: (1) atomistic, reductive analysis and (2) Systems analysis. Correspondingly, atomism is the conception according to which the simplest (smallest) indivisible entity of a certain kind is most fundamental; while systemism, as will be articulated here, is the conception according to which the bonds that structure wholes are most fundamental, and scale and/or constituting entities (...) are of no significance whatsoever for fundamentality. Accordingly, atomists maintain that the basic entities—the atoms—are fundamental, and together with the “external” interactions among them, are sufficient for illuminating all the features and behaviors of the wholes they constitute; whereas systemists proclaim that it is instead structural qualities of systems, that flow from internal relations among their constituents and translate directly into behaviors, that are fundamental, and by themselves largely (if not entirely) sufficient for illuminating the features and behaviors of the wholes thereby structured. Systemism, as will be argued, is consistent with the nonexistence of a fundamental “level” of nondecomposable entities, just as it is consistent with the existence of such a level. Still, systemism is a conception of the fundamental in quite different, but still ontological terms. Systemism can serve the special sciences—the social sciences especially—better than the conception of fundamentality in terms of atoms. Systemism is, in fact, a conception of fundamentality that has rather different uses—and importantly, different resonances. This conception of fundamentality makes contact with questions pertaining to natural kinds and their situation in the metaphysics of the special sciences—their situation within an order of autonomous sciences. The controversy over fundamentality is evident in the social sciences too, albeit somewhat imperfectly, in the terms of debate between methodological individualists and functionalists/holists. This article will thus clarify the difference between systemism and holism. (shrink)

:It is often claimed that libertarianism offers an unattractive conception of free will and moral responsibility because it renders free agency inexplicable and irrational. This essay aims, first, to show that the soundness of these objections turns on more basic disagreements concerning the ideals of free agency and, second, to develop and motivate a truly libertarian conception of the ideals of free agency. The central contention of the essay is that the heart of libertarians’ ideal of free agency is the (...) ideal of agential fundamentality. (shrink)

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)

Much philosophy presupposes a picture of reality as stratified into levels or layers. Yet a precise articulation of such a picture has been missing. It is tempting to think that we now have the tools to remedy this, notably due to ground-theoretic accounts of relative fundamentality. One might expect levels of facts, and their hierarchical arrangement, to be definable from relative fundamentality among facts. I show that such a project can at best partially succeed, by establishing certain limitative (...) results. Moreover, I argue that the limitations should not be surprising, in light of an analogy between levels of reality and instants of time. Facts may exist at more than one level, just like persisting objects exist at more than one time. Finally, I develop a new positive proposal, on which levels are not made up of facts, but of what I call “fact realisations”—roughly, facts together with a complete genealogy of their grounds.

In a recent paper Barnes proposes to characterize ontological emergence by identifying the emergent entities with those entities which are both fundamental and dependent. Barnes offers characterizations of the notions of fundamentality and dependence, but is cautious about committing to the specifics of these notions. This paper argues that Barnes’s characterization of emergence is problematic in several ways. Firstly, emergence is a relation, and merely delimiting relata of this relation tells us little about it. Secondly, the group of entities (...) delimited as dependent and fundamental do not appear to be the group of emergent entities. Rather, some entities appear to be dependent and fundamental and not emergent, whilst other entities appear to be emergent and not dependent and fundamental. The moral drawn is that in order to provide a characterization of emergence one must go beyond what Barnes says explicitly. It is also shown that a potentially fruitful way of doing this would be to further specify the notion of dependence at issue revealing it to be asymmetric and perhaps merely nomological. (shrink)

There are many variants of deflationism about truth, but one of them, Paul Horwich’s minimalism, stands out because it accepts as axiomatic practical variants of the equivalence schema: 〈p〉 is true if and only if p. The equivalence schema is epistemologically fundamental. In this paper, I call upon empirical studies to show that practical variants of the equivalence schema are widely accepted by non-philosophers. While in the empirical data there is variation in how non-philosophers and philosophers talk about truth and (...) how they judge that a proposition is true, a significant amount of data collected over the years reveal that the ordinary or folk view of truth is compatible with the epistemological fundamentality of alethic minimalism. This, I take it, suggests that people share in the same intuitions that form the bedrock of Horwich’s minimalism. (shrink)

Sider’s Writing the Book of the World gives an account of fundamentality in terms of his central ideological notion ‘structure’. Here I first argue against Sider’s claim that to be fundamental to a degree is to be structural to a degree. I argue there’s a pair of properties, P1 and P2, such that P1 is the more fundamental, but Sider is committed to counting P2 as the more structural. I then argue that if relative structure and relative fundamentality (...) can come apart in this way, then Sider is likely also wrong to identify being absolutely structural with being absolutely fundamental.
