    Gappy, glutty, glappy
    Synthese 1-17. forthcoming.
    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 paper provides the first thorough assessment of a physics-based answer, the so called Bound State Answer, to the Special Composition Question. According to the BSA some material objects compose something iff 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 c…Read more

    Determinables, location, and indeterminacy
    Synthese 198 (5): 4191-4204. 2019.
    Discussions about determinables and determinates, on the one hand, and discussions about 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 determinables and location. First, I argue that some well known principles of location turn out to be instances of principles relating determinables and determinates. Building on this I then argue that theories o…Read more

    Quantum Indeterminacy and the Double-Slit Experiment
    with Jessica Wilson
    Philosophical Studies 1 1-27. 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

    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 (6): 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 1-17. forthcoming.
    The possibility of multilocation --- 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 …Read more

    Physics and Metaphysics
    Humana Mente 4 (13). 2018.
    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

    Is parthood identity?
    Synthese 1-15. forthcoming.
    According to a well known, yet controversial metaphysical thesis, Composition is Identity. Recently, Kris McDaniel has articulated and defended a related—and arguably more controversial—thesis, one he calls Parthood is Identity. Roughly the view has it that a whole is, strictly and literally, identical to each of its parts considered individually. At first sight, the view seems rather implausible. However, McDaniel’s formulation and defense are worthy of a serious discussion. In this paper I put…Read more

    Priority monism, dependence and fundamentality
    Philosophical Studies 177 (1): 1-20. 2020.
    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 …Read more

    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

    Failure of Boredom: The Pendulum of Composition as Identity
    American Philosophical Quarterly 55 (3): 281-292. 2018.
    This paper provides new arguments for the following claim: either strong composition as identity cannot retain the full strength of both the logical principles of one-one identity and its semantical principles or it only delivers cases of boring composition in that it entails mereological nihilism.

    Quantum monism: an assessment
    Philosophical Studies 175 (12): 3217-3236. 2018.
    Monism is roughly the view that there is only one fundamental entity. One of the most powerful argument in its favor comes from quantum mechanics. Extant discussions of quantum monism are framed independently of any interpretation of the quantum theory. In contrast, this paper argues that matters of interpretation play a crucial role when assessing the viability of monism in the quantum realm. I consider four different interpretations: modal interpretations, Bohmian mechanics, many worlds interp…Read more

    Composition, identity, and emergence
    Logic and Logical Philosophy 25 (3): 429-443. 2016.
    Composition as Identity is the thesis that a whole is, strictly and literally, identical to its parts, considered collectively. McDaniel [2008] argues against CAI in that it prohibits emergent properties. Recently Sider [2014] exploited the resources of plural logic and extensional mereology to undermine McDaniel’s argument. He shows that CAI identifies extensionally equivalent pluralities – he calls it the Collapse Principle – and then shows how this identification rescues CAI from the emergent…Read more

    Quantum metaphysical indeterminacy
    Philosophical Studies 176 (10). 2019.
    On many currently live interpretations, quantum mechanics violates the classical supposition of value definiteness, according to which the properties of a given particle or system have precise values at all times. Here we consider whether either metaphysical supervaluationist or determinable-based approaches to metaphysical indeterminacy can accommodate quantum metaphysical indeterminacy (QMI). We start by discussing the standard theoretical indicator of QMI, and distinguishing three seemingly …Read more

    On the possibility of submergence
    Analysis 77 (3): 501-511. 2017.
    Are submergence and submergent properties metaphysically possible? This is a substantive question that has been either utterly neglected or quickly answered in the negative. This neglect is not only significant in itself; the possibility of submergence plays a crucial role in hotly debated topics in metaphysics, for example, the debate over Monism and Pluralism. This paper is intended to prompt a discussion about metaphysical submergence. In particular I will provide examples of submergent prope…Read more

    A scholarly annotated epic poem on the pitfalls and tribulations of “good philosophizing”. Divided into twenty-eight cantos (in medieval Italian hendecasyllabic terza rima), the poem tells of an allegorical journey through the downward spiral of the philosophers’ hell, where all sorts of thinkers are punished for their faults and mistakes, in the endeavor to reach a way out of the condition of intellectual impasse in which the narrator has found himself. The affinities with Dante’s Inferno are a…Read more

    Extensionality, Multilocation, Persistence
    Dialectica 68 (1): 121-139. 2014.
    The paper addresses various questions about the logical and metaphysical relations between notions of parthood, location and persistence. In particular it argues that the conjunction of mereological extensionalism and multilocation, is highly problematic, if not utterly inconsistent. It thus provides an alternate route to reject multilocation, one that does not rely on Barker and Dowe's well known argument, at least for those who endorse extensionality of parthood. It then argues that other majo…Read more

    Arrows, Balls and the Metaphysics of Motion
    Axiomathes 24 (4): 499-515. 2014.
    The arrow paradox is an argument purported to show that objects do not really move. The two main metaphysics of motion, the At–At theory of motion and velocity primitivism, solve the paradox differently. It is argued that neither solution is completely satisfactory. In particular it is contended that there are no decisive arguments in favor of the claim that velocity as it is constructed in the At–At theory is a truly instantaneous property, which is a crucial assumption to solve the paradox. If…Read more

    I give two new uniqueness results for the standard relation of simultaneity in the context of metrical time oriented Minkowski spacetime. These results improve on the classic ones due to Malament and Hogarth, for they adopt only minimal uncontroversial assumptions. I conclude addressing whether these results should be taken to definitely refute the general epistemological thesis of conventionalism

    Composition is Identity and Mereological Nihilism
    Philosophical Quarterly 66 (263): 219-235. 2016.
    Composition is Identity is the thesis that a whole is, strict and literally, its parts considered collectively. Mereological Nihilism is the thesis that there are no composite objects whatsoever instead. This paper argues that they are equivalent, at least insofar as Composition is Identity is phrased in a particular way. It then addresses some consequences of such equivalence.

    Quantum mechanics and Priority Monism
    Synthese 191 (5): 1-14. 2014.
    The paper address the question of whether quantum mechanics (QM) favors Priority Monism, the view according to which the Universe is the only fundamental object. It develops formal frameworks to frame rigorously the question of fundamental mereology and its answers, namely (Priority) Pluralism and Monism. It then reconstructs the quantum mechanical argument in favor of the latter and provides a detailed and thorough criticism of it that sheds furthermore new light on the relation between parthoo…Read more
