    Multilocation, Fusions, and Confusions
    Philosophia 43 (1): 25-33. 2015.
    The paper provides a new and detailed critique of Barker and Dowe’s argument against multi-location. This critique is not only novel but also less committal than previous ones in the literature in that it does not require hefty metaphysical assumptions. The paper also provides an analysis of some metaphysical relations between mereological and locational principles

    Back to Black
    Ratio 29 (1): 1-10. 2016.
    This is a brief sequel to Max Black 's classic dialogue on the Identity of Indiscernibles. Interlocutor A defends the bundle theory by endorsing the view according to which Black 's world does not contain two indiscernible spheres but rather a single, bi-located sphere. His opponent, B, objects that A cannot distinguish such a world from a world with a single, uniquely located sphere, hence that the view in question adds nothing to A's original response to Black 's challenge. A is simply denying…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

    Minimality, Geometry and Simultaneity
    Iris. European Journal of Philosophy and Public Debate 2 (4): 451-465. 2010.
    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

    In this paper, we focus on two related reductive theses in metaphysics—Humean Supervenience and Composition as Identity—and on their status in light of the indications coming from science, in particular quantum mechanics. While defenders of these reductive theses claim that they can be updated so as to resist the quantum evidence, we provide arguments against this contention. We claim that physics gives us reason for thinking that both Humean Supervenience and Composition as Identity are at leas…Read more

    An elegant universe
    Synthese 1-16. 2017.
    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

    Metaphysics of Time in Spacetime
    Thought: A Journal of Philosophy 3 (1): 1-8. 2014.
    I give a new and more general argument against presentism within relativistic spacetimes. This argument is untouched by different recent proposals designed to save presentism in a relativistic setting

    In this paper, we address an infamous argument against divisibility that dates back to Zeno. There has been an incredible amount of discussion on how to understand the critical notions of divisibility, extension, and infinite divisibility that are crucial for the very formulation of the argument. The paper provides new and rigorous definitions of those notions using the formal theories of parthood and location. Also, it provides a new solution to the paradox of divisibility which does not face s…Read more
