This paper lays out the basic structure of any view involving coincident entities, in the light of the grounding problem. While the account is not novel, I highlight fundamental features, to which attention is not usually properly drawn. With this in place, I argue for a number of further claims: The basic differences between coincident objects are modal differences, and any other differences between them need to be explained in terms of these differences. More specifically, the basic difference is not (...) a difference in sort. A number of recent defenses of coincidence, which share the basic structure I outline, misidentify what, in their accounts, plays the basic role of addressing the grounding problem. More tentatively, I argue Coincident entities differ only in these modal properties, and properties they entail. In particular, they do not differ in properties like ‘being a tree,’ ‘being a statue,’ or aesthetic properties, and finally in light of how the account of coincidence offered addresses the grounding problem, the grounding problem provides no reason to prefer monism to pluralism.

In this paper I present and critically discuss Simon Evnine’s account of hylomorphically complex objects (as presented in his 2016 book Making Objects and Events). On the one hand, I object to the account he gives of how artifacts (which are for him the paradigmatic cases of hylomorphically complex objects) allegedly acquire their existence and identity conditions. I elaborate on two problems I see for this account: first, that it seems unable to explain our knowledge of the kinds to which (...) artifacts belong; second, that it cannot offer a plausible solution to the grounding problem for coincident objects. I also object to the way in which he tries to adapt the sort of account he gave for artifacts to the case of organisms (in my view this fails because both cases are dissimilar at crucial points), and finally I also object to his attempt to extend that account, in a fictional way, to the case of natural non-organic objects (as I try to show, both his arguments to the effect that there are no such objects, and his positive fictionalist proposal to account for our talk about them, are flawed).

Are a material object, such as a statue, and its constituting matter, the clay, parts of one another? One wouldn't have thought so, and yet a number of philosophers have argued that they are. I review the arguments for this surprising claim showing how they all fail. I then consider two arguments against the view concluding that there are both pre-theoretical and theoretical considerations for denying that the statue and the clay are mutual parts.

Social groups, including racial and gender groups and teams and committees, seem to play an important role in our world. This article examines key metaphysical questions regarding groups. I examine answers to the question ‘Do groups exist?’ I argue that worries about puzzles of composition, motivations to accept methodological individualism, and a rejection of Racialism support a negative answer to the question. An affirmative answer is supported by arguments that groups are efficacious, indispensible to our best theories, and accepted given (...) common sense. Then, I turn to an examination of the features of social groups. I argue that social groups can be divided into two sorts. Groups of Type 1 are organized social groups like courts and clubs. Groups of Type 2 are groups like Blacks, women, and lesbians. While groups of both sorts have some features in common, they also have marked differences in features. Finally, I turn to views of the nature of social groups. I argue that the difference in features provides evidence that social groups do not have a uniform nature. Teams and committees are structured wholes, while race and gender groups are social kinds. (shrink)

The Doctrine of Microphysical Supervenience states that microphysical duplicates cannot differ in their intrinsic properties. According to Merricks :59–71, 1998a, Objects and persons, Oxford University Press, 2001), however, this thesis is false, since microphysical duplicates can differ with respect to the intrinsic property of consciousness. In my view, Merricks’ argument is plausible, and extant attempts to reject it are problematic. However, the argument also threatens to make consciousness appear mysterious, by implying that consciousness facts fail to be microphysically determined and (...) that there can be brute and inexplicable differences in consciousness between material things. The paper therefore develops an account that can respect the soundness of Merricks’ argument while avoiding these problematic consequences. At the heart of the proposal is the idea that consciousness can be microphysically grounded despite failing to microphysical supervene. The proposed view also has the interesting consequence that consciousness is an intrinsic property despite depending on extrinsic factors for its instantiation. (shrink)

Are grounding claims fully general in character? If an object a is F in virtue of being G, does it follow that anything that’s G is F for that reason? According to the thesis of Weak Formality, the answer here is ‘yes’. In this paper, however, I argue that there is philosophical utility in rejecting this thesis. More exactly, I argue that two currently unresolved problems in contemporary metaphysics can be dealt with if we hold that there can be cases (...) of ‘kind-dependent grounding’, the key thought being that once we allow for such cases, we must also accept that Weak Formality is false.

One of the central debates in contemporary metaphysics has been the debate between endurantism and perdurantism about persistence. In this paper I argue that much of this debate has been misconstrued: most of the arguments in the debate crucially rely on theses which are strictly orthogonal to the endurantism/perdurantism debate. To show this, I note that the arguments in the endurantism/perdurantism debate typically take the following form: one presents a challenge that endurantists allegedly have some trouble addressing, and to which (...) perdurantism apparently has a straightforward response. I argue, however, that in each case, there are versions of endurantism that can offer precisely the same response to the challenge, and thus the ability to provide this particular solution does not directly tell in favour of one the two views. In §1, I elaborate two views which will be particularly prominent in the discussion: liberal endurantism and restrictive perdurantism. In §2–6 I discuss in turn the central pro-perdurantism arguments: the argument from anthropocentricism, the argument from vagueness, the argument from recombination, the argument from temporary intrinsics, and the argument from coincidence. In §7–8, I discuss the main pro-endurantism arguments: the arguments from motion, and the argument from permanent coincidence. Finally, in §9, I discuss what conclusion can be drawn from this discussion. (shrink)

It is both a matter of everyday experience and a tenet of sociological theory that people often occupy a range of social roles and identities, some of which are associated with mutually incompatible properties. But since nothing could have incompatible properties, it is not clear how this is possible. It has been suggested, notably by Kit Fine (1982, 1999, 2006), that the puzzling relation between a person and their various social roles and identities can be explained by admitting an ontology (...) of social qua objects—objects constituted by, yet distinct from, the persons on which they are based. This article argues that admitting even a rich ontology of such qua objects does not suffice to explain the puzzle cases of interest. Instead, alternative resources are required which, once available, diminish the motivation for adopting an ontology of social qua objects in the first place. The paper concludes by considering whether there remains work for social qua objects in explaining differences in persistence conditions between a person and the social individuals to which they may give rise, but reaches a negative verdict. Social qua objects, if they exist, have little work to do in our theorizing about the relation between a person and their various social roles and identities. (shrink)

Mereonominalism, holonominalism, and part-whole realism represent competing views on the metaphysics of parts and wholes. Mereonominalism claims that what parts exist is a function of the concepts we use in describing composite wholes. Holonominalism claims that what composite wholes exist is a function of the concepts we use in describing things that can qualify as parts. Part-whole realism claims that parts and wholes exist independent of our concepts. I argue that all three views face problems, but that the problem facing (...) part-whole realism can be solved by adopting a version of hylomorphism that takes its cue from Aristotle’s account of form.

The hard problem of consciousness has held center stage in the philosophy of mind for the past two decades. It claims that the phenomenal character of conscious experiences—what it’s like to be in them—cannot be explained by appeal to the operation of physiological subsystems. The hard problem arises, however, only given the assumption that hylomorphism is false. Hylomorphism claims that structure is a basic ontological and explanatory principle. A human is not a random collection of physical materials, but an individual (...) composed of physical materials with a structure that accounts for what it is and what it can do—the powers it has. What is true of humans is true of their activities as well. The latter are not random physiological changes, but structured ones: we engage in them by coordinating the ways our parts manifest their powers. Structured activities include perceptual experiences. Consequently, everything about a perceptual experience, including its phenomenal character, can be explained by describing the perceiver’s perceptual subsystems, the powers of those subsystems, and the coordination that unifies their activities into the activity of the perceiver as a whole. Conscious experiences thus fit unproblematically into the natural world—just as unproblematically as the phenomenon of life. Even exponents of the hard problem of consciousness agree that there is no hard problem of life. Consequently, if hylomorphism is true, there can be no hard problem of consciousness. To insist that there is such a problem, then, is implicitly to reject hylomorphism. The concept of consciousness that motivates the hard problem is as much a theoretical construct, therefore, as the concept of life that motivates an obstinate vitalist. (shrink)

The paper comprises an attempt on the part of the author to understand what hylomorphism is, both in its original Aristotelian guise, and in recent work by philosophers who defend what they call hylomorphism. Two species or strands of hylomorphism are identified and discussed. Universals, essences, and substantial and accidental forms make cameo appearances, and the implications of an Aristotelian ontology of stuffs are explored.

Several social metaphysicians have argued that groups are constituted by, but not identical to, their members. While the constitution view is promising, there are significant difficulties with existing versions of that view. Fortunately, lessons may be extracted from more traditional metaphysics and applied to the case of group agents. Drawing on such lessons, I present a novel account of the constitution relation holding between individuals and group agents. According to the resulting structural-constitution view, when individuals constitute a group of a (...) certain kind, they do so in virtue of exhibiting the structure characteristic of groups of that kind.

The view that ordinary objects are composites of form and matter ("hylomorphism") can be contrasted with the more common view that ordinary objects are composed of only material parts ("matter only"). On a matter-only view the hard question is modal: which modal profile does that (statue-shaped) object have? Does it have the modal profile of a statue, a lump, a mere aggregate? On a hylomorphic view the hard question is ontological: which objects exist? Does a statue (matter-m + statue-form), a (...) lump (matter-m + lump-form), and/or a mere aggregate (matter-m + mere aggregate-form) exist? I defend a novel answer to the hard question for hylomorphism. In particular, I argue that which ordinary objects exist depends, in part, on how subjects respond to the matter they encounter. I argue that, with regard to grounding the existence and modal properties of ordinary objects, response-dependent hylomorphism is superior to both matter only views and to non-response-dependent versions of hylomorphism.

On the grounds that there are no mereological composites, mereological nihilists deny that ordinary objects exist. Even if nihilism is true, however, I argue that tables and chairs exist anyway: for I deny that ordinary objects are the mereological sums the nihilist rejects. Instead, I argue, ordinary objects have a different nature; they are arrangements, not composites. My argument runs as follows. First, I defend realism about ordinary objects by showing that there is something that plays the role of ordinary (...) objects in perception and discourse, and that ordinary objects are whatever plays this role. Next, I argue that it is arrangements that play this role. It follows that ordinary objects exist- even if mereological nihilism is true. (shrink)

I apply the theory of embodiment to various questions concerning the identity of social groups.

In the face of the puzzles of material constitution, some philosophers have been moved to posit a distinction between an object's matter and its form. A familiar difficulty for contemporary hylomorphism is to say which properties are eligible as forms: for example, it seems that it would be intolerably arbitrary to say that being statue shaped is embodied by some material object, but that other complex shape properties aren't. Anti-arbitrariness concerns lead quickly to a plenitudinous ontology. The usual complaint is (...) that the super-abundance of material objects is too extraordinary to accept, but I want to raise a different worry: I argue that the most natural way of developing this picture is already inconsistent. I show that a simple version of plenitudinous hylomorphism is subject to a Russellian argument, but argue that we cannot treat the problem straightforwardly as an instance of Russell's Paradox of Sets.

This paper defends a conceptualist answer to the question how objects come by their modal properties. It isolates the controversial metaphysical assumptions that are needed to get ontological conceptualism off the ground, outlines the conceptualist answer to the question and shows that conceptualism is not in as bad a shape as some critics have maintained.

A philosophical standard in the debates concerning material constitution is the case of a statue and a lump of clay, Goliath and Lumpl, respectively. According to the story, Lumpl and Goliath are coincident throughout their respective careers. Monists hold that they are identical; pluralists that they are distinct. This paper is concerned with a particular objection to pluralism, the Grounding Problem. The objection is roughly that the pluralist faces a legitimate explanatory demand to explain various differences she alleges between Lumpl (...) and Goliath, but that the pluralist’s theory lacks the resources to give any such explanation. In this paper, I explore the question of whether there really is any problem of this sort. I argue (i) that explanatory demands that are clearly legitimate are easy for the pluralist to meet; (ii) that even in cases of explanatory demands whose legitimacy is questionable the pluralist has some overlooked resources; and (iii) there is some reason for optimism about the pluralist’s prospects for meeting every legitimate explanatory demand. In short, no clearly adequate statement of a Grounding Problem is extant, and there is some reason to believe that the pluralist can overcome any Grounding Problem that we haven’t thought of yet.

Consider the kinds of macroscopic concrete objects that common sense and the sciences allege to exist: tables, raindrops, tectonic plates, galaxies, and the rest. Are there any such things? Opinions differ. Ontological liberals say they do; ontological radicals say they don't. Liberalism seems favored by its plausible acquiescence to the dictates of common sense abetted by science; radicalism by its ontological parsimony. Priority theorists claim we can have the virtues of both views. They hold that tables, raindrops, etc., exist, but (...) they aren't fundamental. The ontological liberal's ontology provides the correct inventory of existent individuals. The ontological radical's more restricted ontology provides the correct inventory of fundamental individuals. The priority theorist claims that the derivative individuals are "no addition in being" to the fundamental ones, so we can have our cake and eat it too. It would be nice if priority theorists were right. In this paper I argue, with regret, that they are not. One upshot is that the sort of explanations which underwrite the priority theorist's distinction between fundamental and derivative individuals do not mitigate our ontological commitments. Another is that we still have to choose between the charms of liberalism and radicalism. (shrink)

In this essay, I examine those versions of hylomorphism that attribute to form a very strong explicative role. According to them, form is both the source of new emergent powers and expression of the finalist structure of organisms. The main aim of this essay is to show that these two aspects do not holdup because the form only exercises a structural function, but does not exert an autonomous explanatory function. The form only allows the material components to develop those powers (...) that are not manifest in themselves, outside the configuration that forms as structure gives them. If the higher faculties of the human mind are really emergent over the neurophysiological ones, hylomorphism cannot explain it. As a consequence, hylomorphism does not have the resources to oppose materialism, on the one hand, and dualism, on the other. (shrink)

Let us consider a statue and the piece of clay out of which it is made, and let us suppose that they start to exist and cease to exist at exactly the same time. According to colocationism, the statue and the piece of clay are two different objects: they have different properties and, according to Leibniz’s Law, the same object cannot have different properties. One of the most difficult questions for colocationism is that of the grounding problem : given that (...) the statue and the piece of clay share many of their properties, what is it that grounds the fact that they have different sortal properties? Recently, Catherine Sutton has offered a very interesting answer to the question. However, as I will argue, it cannot be applied to all cases of colocated objects and therefore, it is not an adequate solution to the grounding problem. The main objective of this paper is to present a new solution to the grounding problem that integrates some of Sutton’s theses, but that allows us to give a complete answer to the question. To do this, the notion of a process of coming into existence will be crucial. After presenting the new proposal, I will compare it with the proposals by Kit Fine and Noël Saenz. (shrink)

Unger has recently argued that if you are the only thinking and experiencing subject in your chair, then you are not a material object. This leads Unger to endorse a version of Substance Dualism according to which we are immaterial souls. This paper argues that this is an overreaction. We argue that the specifically Dualist elements of Unger’s view play no role in his response to the problem; only the view’s structure is required, and that is available to Unger’s opponents. (...) We outline one such non-Dualist view, suggest how to resolve the dispute, respond to some objections, and argue that ours is but one of many views that survive Unger’s challenge. All these views are incompatible with microphysicalism. So Unger’s discussion does contain an insight: if you are the only conscious subject in your chair, then microphsyicalism is false. Unger’s mistake was to infer Substance Dualism from this; for microphysicalism is not the only alternative to Dualism. (shrink)

As there is currently a neo-Aristotelian revival currently taking place within contemporary metaphysics and dispositions, or causal powers are now being routinely utilised in theories of causality and modality, more attention is beginning to be paid to a central Aristotelian concern: the metaphysics of substantial unity, and the doctrine of hylomorphism. In this paper, I distinguish two strands of hylomorphism present in the contemporary literature and argue that not only does each engender unique conceptual difficulties, but neither adequately captures the (...) metaphysics of Aristotelian hylomorphism. Thus both strands of contemporary hylomorphism, I argue, fundamentally misunderstand what substantial unity amounts to in the hylomorphic framework – namely, the metaphysical inseparability of matter and form.

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...) (1958) thesis that the predictive power of a scientific theory is directly proportional to its explanatory potential, and vice versa. (shrink)
