    Basic Problems of Mereotopology
    In Nicola Guarino (ed.), Formal Ontology in Information Systems, Ios Press. 1998.
    Mereotopology is today regarded as a major tool for ontological analysis, and for many good reasons. There are, however, a number of open questions that call for an answer. Some are philosophical, others have direct applicative import, but all are crucial for a proper assessment of the strengths and limits of mereotopology. This paper is an attempt to put sum order in this area.

    The Universe among Other Things
    Ratio 19 (1). 2006.
    Peter Simons has argued that the expression ‘the universe’ is not a genuine singular term: it can name neither a single, completely encompassing individual, nor a collection of individuals. (It is, rather, a semantically plural term standing equally for every existing object.) I offer reasons for resisting Simons’s arguments on both scores.

    Playing for the Same Team Again
    with Matthew Slater
    In Bassham & Walls (eds.), Basketball and Philosophy, University of Kentucky Press. 2007.
    How many championships have the Lakers won? Fourteen, if one counts those won in Minneapolis; nine, otherwise. Which is the correct answer? Is it even obvious that there is a correct answer? One is tempted to identify a team with its players. But teams, like ordinary objects, seem to survive gradual turnover of their parts. Suppose players from the Lakers are gradually replaced, one by one, over the years. We have the intuition that the team persists through this change, even after none of the o…Read more

    The Best Question
    Journal of Philosophical Logic 30 (3): 251-258. 2001.
    Suppose we get a chance to ask an angel a question of our choice. What should we ask to make the most of our unique opportunity? Ned Markosian has shown that the task is trickier than it might seem. Ted Sider has suggested playing safe and asking: What is the true proposition (or one of the true propositions) that would be most beneficial for us to be told? Let's see whether we can do any better than that.

    La metafisica è quel ramo della filosofia che ha come oggetto la realtà considerata nei suoi aspetti più fondamentali e generali. L’origine del termine (letteralmente: ‘dopo’ o ‘oltre la fisica’) risale agli editori delle opere di Aristotele nel I secolo a.C., che lo usarono per classificare gli scritti dedicati a quest’argomento e ritenuti, appunto, posteriori a quelli dedicati alla fisica. L’essere si dice in molti modi, scriveva Aristotele in quelle pagine, e a questa molteplicità di signific…Read more

    A Note on Analysis and Circular Definitions
    Grazer Philosophische Studien 54 107-113. 1998.
    Analyses, in the simplest form assertions that aim to capture an intimate link between two concepts, are viewed since Russell's theory of definite descriptions as analyzing descriptions. Analysis therefore has to obey the laws governing definitions including some form of a Substitutivity Principle (SP). Once (SP) is accepted the road to the paradox of analysis is open. Popular reactions to the paradox involve the fundamental assumption (SV) that sentences differing only in containing an analysan…Read more

    Giornale di Metafisica 29 (2): 285-303. 2007.

    with Fabio Pianesi
    In James Higginbotham, Fabio Pianesi & Achille C. Varzi (eds.), Speaking of events, Oxford University Press. 2000.
    A critical review of the main themes arising out of recent literature on the semantics of ordinary event talk. The material is organized in four sections: (i) the nature of events, with emphasis on the opposition between events as particulars and events as universals; (ii) identity and indeterminacy, with emphasis on the unifier/multiplier controversy; (iii) events and logical form, with emphasis on Davidson’s treatment of the form of action sentences; (iv) linguistic applications, with emphasis…Read more
