    According to Relational Quantum Mechanics the wave function \ is considered neither a concrete physical item evolving in spacetime, nor an object representing the absolute state of a certain quantum system. In this interpretative framework, \ is defined as a computational device encoding observers’ information; hence, RQM offers a somewhat epistemic view of the wave function. This perspective seems to be at odds with the PBR theorem, a formal result excluding that wave functions represent knowle…Read more

    By(e) enduring? An answer to Wasserman
    Synthese 202 (4): 1-12. 2023.
    According to a recent argument due to Wasserman, endurantism does not qualify as an explanatory theory of persistence inasmuch as it either provides a circular account of persistence facts or merely rejects the perdurantist’s explanation of such facts. This paper challenges Wasserman’s conclusions by pointing out that an endurantist answer to his complaint is available thanks to the locational notions of persistence provided in the work of Gilmore, Parsons, Balashov among others. It then gives d…Read more

    One might suppose that Everettian quantum mechanics (EQM) is inhospitable to metaphysial indeterminacy (MI), given that, as A. Wilson (2020) puts it, "the central idea of EQM is to replace indeterminacy with multiplicity" (77). But as Wilson goes on to suggest, the popular decoherence-based understanding of EQM (henceforth: DEQM) appears to admit of indeterminacy in both world number and world nature, where the latter indeterminacy---our focus here---is plausibly metaphysical. After a brief pres…Read more

    Interpreting Quantum Entanglement: Steps towards Coherentist Quantum Mechanics
    British Journal for the Philosophy of Science 72 (3): 865-891. 2021.
    We put forward a new, ‘coherentist’ account of quantum entanglement, according to which entangled systems are characterized by symmetric relations of ontological dependence among the component particles. We compare this coherentist viewpoint with the two most popular alternatives currently on offer—structuralism and holism—and argue that it is essentially different from, and preferable to, both. In the course of this article, we point out how coherentism might be extended beyond the case of enta…Read more

    La fondazione della conoscenza nell’estetica di Croce: una lettura ‘analitica’
    Annali Del Dipartimento di Filosofia 14 107-131. 2008.
    I interpret the first part of Croce’s Estetica as an example of ageneral foundational argument about knowledge. I argue thatCroce uses correctly this very general argumentative structure.I argue that this foundational attempt could not be read neitheras a trascendental nor a reductionist attempt. I suggest that thevery best way to look at it is to be found in Croce’s later works.I then conclude with some problems that arises within the foundational context.Keywords: knowledge, foundationalism, i…Read more

    On the Contingency of Universalism
    Erkenntnis 88 (5): 1997-2011. 2023.
    The paper presents different arguments against the necessity of mereological universalism. First, it argues that they are examples of a much more general argumentative structure. It then contends that some of these arguments cannot be resisted by distinguishing different variants of universalism that have been recently proposed in the literature—in contrast with recent suggestions to the contrary. Finally, it provides different ways to resist such contingentist arguments on behalf of universalis…Read more

    Atoms, combs, syllables and organisms
    Philosophical Studies 180 (7): 1995-2024. 2023.
    Mereological atomism is the thesis that everything is ultimately composed of atomic parts, i.e., parts without proper parts. Typically, this thesis is characterized by an axiom stating that everything has atomic parts. The present paper argues that the success of this standard characterization depends on how the notions of sum and composition are defined. In particular, we put forward a novel definition of mereological sum that: (i) is not equivalent to existing definitions in the literature, if…Read more

    Universalism and extensionalism revisited
    Synthese 201 (3): 1-18. 2023.
    We present a new notion of mereological sum that is inequivalent to extant ones in the literature and does not fall prey to reasonable complaints that can be raised against some such notions. In light of this notion, we then revisit the relation between mereological universalism and extensionalism. In particular we argue that Varzi’s claim to the point that universalism entails extensionalism is justified only insofar as one sticks to Varzi’s notion of sum. In effect, we distinguish different ve…Read more

    Extended Simples, Unextended Complexes
    Journal of Philosophical Logic 52 (2): 643-668. 2023.
    Both extended simples and unextended complexes have been extensively discussed and widely used in metaphysics and philosophy of physics. However, the characterizations of such notions are not entirely satisfactory inasmuch as they rely on a mereological notion of extension that is too simplistic. According to such a mereological notion, being extended boils down to having a mereologically complex exact location. In this paper, I make a detailed plea to supplement this notion of extension with a …Read more

    Multilocation – the notion of an object being 18756735_00000147_text.pdfat two places – is a central notion in metaphysics. According to a widespread view, multilocation is problematic but metaphysically possible. In effect, it has been claimed that in a quantum world, multilocation is not simply possible but actual. This article provides a new argument against the latter claim: there is no quantum multilocation.

    The general-relativistic case for super-substantivalism
    with Patrick M. Duerr
    Synthese 199 (5-6): 13789-13822. 2021.
    Super-substantivalism (of the type we’ll consider) roughly comprises two core tenets: (1) the physical properties which we attribute to matter (e.g. charge or mass) can be attributed to spacetime directly, with no need for matter as an extraneous carrier “on top of” spacetime; (2) spacetime is more fundamental than (ontologically prior to) matter. In the present paper, we revisit a recent argument in favour of super-substantivalism, based on General Relativity. A critique is offered that highlig…Read more

    Inheriting harmony
    Analysis 82 (1): 23-32. 2022.
    Supersubstantivalism, the view that material objects are identical to their locations, has recently been defended in metaphysics and philosophy of physics. One of the most powerful arguments in its favour is the so-called argument from harmony. There is a certain harmony between material objects and their locations. Necessarily, if material object x is located at a spherical region, x is spherical. Necessarily, if material object x is located at region r, any part of x is located at a part of r.…Read more

    Fine’s Monster Objection Defanged
    Philosophical Quarterly 73 (2): 435-451. 2023.
    The Monster Objection has often been considered one of the main reasons to explore non-standard mereological views, such as hylomorphism. Still, it has been rarely discussed and then only in a cursory fashion. This paper fills this gap by offering the first thorough assessment of the objection. It argues that different metaphysical stances, such as presentism and three- and four-dimensionalism, provide different ways of undermining the objection.

    Quantum indeterminacy and the double-slit experiment
    Philosophical Studies 178 (10): 3291-3317. 2021.
    In Calosi and Wilson (Phil Studies 2019/2018), we argue that on many interpretations of quantum mechanics (QM), there is quantum mechanical indeterminacy (QMI), and that a determinable-based account of metaphysical indeterminacy (MI), as per Wilson 2013 and 2016, properly accommodates the full range of cases of QMI. Here we argue that this approach is superior to other treatments of QMI on offer, both realistic and deflationary, in providing the basis for an intelligible explanation of the inter…Read more

    Gappy, glutty, glappy
    Synthese 199 (3-4): 11305-11321. 2021.
    According to the Determinable Based Account of metaphysical indeterminacy, there is MI when there is an indeterminate state of affairs, roughly a state of affairs in which a constituent object x has a determinable property but fails to have a unique determinate of that determinable. There are different ways in which x might have a determinable but no unique determinate: x has no determinate—gappy MI, or x has more than one determinate—glutty MI. Talk of determinables and determinates is usually …Read more

    The Bound State Answer to the Special Composition Question
    Philosophy of Science 89 (3): 486-503. 2022.
    This paper provides the first thorough assessment of a physics-based answer, the Bound State Answer, to the Special Composition Question. According to the BSA some objects compose something if they are in a common bound state. The reasons to endorse such an answer, in particular, motivations coming from empirical adequacy and conservativeness, precision, simplicity, and parsimony, are critically addressed. I then go on to compare the BSA to other moderate answers to the SCQ and consider whether …Read more

    Determinables, location, and indeterminacy
    Synthese 198 (5): 4191-4204. 2019.
    Discussions about determinables and determinates, on the one hand, and discussions about (formal) theories of location, on the other, have thus far proceeded without any visible interaction, in substantive mutual neglect. This paper aims to remedy this situation of neglect. It explicitly relates (theories of) determinables and (theories of) location. First, I argue that some well known principles of location turn out to be instances of principles relating determinables and determinates. Building…Read more

    Quantum indeterminacy
    Philosophy Compass 16 (4). 2021.
    This paper explores quantum indeterminacy, as it is operative in the failure of value‐definiteness for quantum observables. It first addresses questions about its existence, its nature, and its relations to extant quantum interpretations. Then, it provides a critical discussions of the main accounts of quantum indeterminacy.

    An elegant universe
    Synthese 197 (11): 4767-4782. 2020.
    David Lewis famously endorsed Unrestricted Composition. His defense of such a controversial principle builds on the alleged innocence of mereology. This innocence defense has come under different attacks in the last decades. In this paper I pursue another line of defense, that stems from some early remarks by van Inwagen. I argue that Unrestricted Composition leads to a better metaphysics. In particular I provide new arguments for the following claims: Unrestricted Composition entails extensiona…Read more

    Is the World a Heap of Quantum Fragments?
    Philosophical Studies 178 2009-2019. 2021.
    Fragmentalism was originally introduced as a new A-theory of time. It was further refined and discussed, and different developments of the original insight have been proposed. In a celebrated paper, Jonathan Simon contends that fragmentalism delivers a new realist account of the quantum state—which he calls conservative realism—according to which: the quantum state is a complete description of a physical system, the quantum state is grounded in its terms, and the superposition terms are themselv…Read more

    The Multi-location Trilemma
    Erkenntnis 87 (3): 1063-1079. 2022.
    The possibility of multi-location—of one entity having more than one exact location—is required by several metaphysical theories such as the immanentist theory of universals and three-dimensionalism about persistence. One of the most pressing challenges for multi-location theorists is that of making sense of exact location—in that extant definitions of exact location entail a principle called ‘functionality’, according to which nothing can have more than one exact location. Recently in a number …Read more

    It is notoriously difficult to define Metaphysics1, its content, its method, its language, its scope. Thus I will not even try an attempt here. I will rest content to point out some widely held characterizations. A long and highly influential tradition maintains that Metaphysics is the study of being qua being. It is concerned with what there is, what kind of things are the things that there are, what properties do they have, how they are related. In this sense Metaphysics deals with the more ge…Read more
