  8. Achille C. Varzi (2011). On Doing Ontology Without Metaphysics. Philosophical Perspectives 25 (1):407-423.
    According to a certain, familiar way of dividing up the business of philosophy, made popular by Quine, ontology is concerned with the question of what there is (a task that is often identified with that of drafting a “complete inventory” of the universe) whereas metaphysics is concerned with the question of what it is (i.e., with the task of specifying the “ultimate nature” of the items included in the inventory).1 For instance, a thesis to the effect that there are such (...)

    Amidst many discussions on super-valuational algebras and their philosophical applications — on which I was writing my dissertation — Hans and I once paused to ponder the mystical experience of the square. I mean A Square, the hero of Flatland. I mean that perfectly two-dimensional being, with no depth whatsoever, citizen of an equally two-dimensional depthless world, who one day had the good fortune of receiving a visit from a Sphere. What's more, he had the fortune of being able to (...)

    1. Universalism (also known as Conjunctivism, or Collectivism) is the thesis that mereological composition is unrestricted. More precisely: (U) Any non-empty collection of things has a fusion, i.e., something that has all those things as parts and has no part that is disjoint from each of them.1 Extensionalism is the thesis that sameness of composition is sufficient for identity. More precisely: (E) No two things have exactly the same proper parts (unless they are atomic, i.e., have no proper parts at (...)

  19. Achille Varzi, Boundary. Stanford Encyclopedia of Philosophy.
    We think of a boundary whenever we think of an entity demarcated from its surroundings. There is a boundary (a surface) demarcating the interior of a sphere from its exterior; there is a boundary (a border) separating Maryland and Pennsylvania. Sometimes the exact location of a boundary is unclear or otherwise controversial (as when you try to trace out the margins of Mount Everest, or even the boundary of your own body). Sometimes the boundary lies skew to any physical discontinuity (...)

  20. Achille Varzi, Holes. Stanford Encyclopedia of Philosophy.
    Holes are an interesting case-study for ontologists and epistemologists. Naive, untutored descriptions of the world treat holes as objects of reference, on a par with ordinary material objects. (‘There are as many holes in the cheese as there are cookies in the tin.’) And we often appeal to holes to account for causal interactions, or to explain the occurrence of certain events. (‘The water ran out because of the hole in the bucket.’) Hence there is..

  21. Achille Varzi (2008). The Extensionality of Parthood and Composition. Philosophical Quarterly 58 (230):108 - 133.
    I focus on three mereological pnnciples: the extensionality of parthood (EP), the uniqueness of composition (UC), and the extensionality of composition (EC). These pnnciples are not equivalent. Nevertheless they are closely related (and often equated), since they all reflect the basic nominalistic dictum No difference without a difference maker'. All of them, individually or collectively, have been challenged on philosophical grounds. In the first part I argue that such challenges do not quite threaten (EP), because they are either self-defeating or (...)

    This issue of The Monist is devoted to the metaphysics of lesser kinds, which is to say those kinds of entity that are not generally recognized as occupying a prominent position in the categorial structure of the world. Why bother? We offer two sorts of reason. The first is methodological. In mathematics, it is common practice to study certain functions (for instance) by considering limit cases: What if x = 0? What if x is larger than any assigned value? Physics, (...)

  24. Achille Varzi (2007). Promiscuous Endurantism and Diachronic Vagueness. American Philosophical Quarterly 44 (2):181 - 189.
    1. According to a popular line of reasoning, vagueness creates a problem for the endurantist conception of persistence.1 Assuming that ordinary material objects can undergo some mereological change without thereby ceasing to exist, just how much change they can tolerate appears to be a vague matter. Surely a cat—Tibbles—can lose a few body cells, but surely it cannot lose too many of them, so it seems that we are bound to be faced with “borderline cases” in which we are unsure (...)

    If we adopt a supervaluational semantics for vagueness, what sort of logic results? As it turns out, the answer depends crucially on how the standard notion of validity as truth preservation is recast. There are several ways of doing this within a supervaluational framework, the main alternative being between 'global' construals (e.g. an argument is valid if and only if it preserves truth-under-all-precisifications) and 'local' construals (an argument is valid if and only if, under all precisifications, it preserves truth). The (...)

    Most event-referring expressions are vague it is utterly difficult, if not impossible, to specify the exact spatiotemporal location of an event from the words that we use to refer to it. We argue that in spite of certain prima facie obstacles, such vagueness can be given a purely semantic (broadly supervaluational) account.

    Part-whole theories, or mereologies (from the Greek word µ ρος, meaning: “share”, “portion”, or “part”), form a central chapter of metaphysics throughout its history. Their roots can be traced back to the earliest days of philosophy, beginning with the Pre-Socratics. It is plausible to hold that Parmenides argues that there can be no parts, thus everything there is is one whole; and Zeno argues for his striking paradoxes on the assumption that there are parts (whether spatial or temporal ones). Democritus (...)

    It is common lore that standard, Kripke-style semantics for quantified modal logic is incompatible with the view that no individual may belong to more than one possible world, a view that seems to require a counterpart-theoretic semantics instead. Strictly speaking, however, this thought is wrong-headed. This note explains why.

    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.

    If the question is: what is to be done for philosophy?, then it calls for a political answer and I have little to say besides the obvious. If the question is: what is to be done in philosophy?, then I’m stuck. Drawing up a list of to-do’s and not-to-do’s would not, I think, be a good way to honor the general conception of philosophy that inspired Topoi throughout these years, and that I deeply share.

    Every criminal act ought to be matched by a corresponding punishment, or so we may suppose, and every punishment ought to reflect a criminal act. We know how to count punishments. But how do we count crimes? In particular, how does our notion of a criminal action depend on whether the prohibited action is an activity, an accomplishment, an achievement, or a state?

    The so-called "argument from vagueness", the clearest formulation of which is to be found in Ted Sider’s book Four-dimensionalism, is arguably the most powerful and innovative argument recently offered in support of the view that objects are four-dimensional perdurants. The argument is defective--I submit--and in a number of ways that is worth looking into. But each "defect" corresponds to a model of change that is independently problematic and that can hardly be built into the common-sense picture of the world. So (...)

    A rejoinder to G. Hull’s reply to my Mind 2003. Hull argues that Sorensen’s purported proof that ‘vague’ is vague--which I defended against certain familiar objections--fails. He offers three reasons: (i) the vagueness exhibited by Sorensen’s sorites is just the vagueness of ‘small’; (ii) the general assumption underlying the proof, to the effect that predicates which possess borderline cases are vague, is mistaken; (iii) the conclusion of the proof is unacceptable, for it is possible to create Sorensen-type sorites even for (...)

    Argle claimed that holes supervene on their material hosts, and that every truth about holes boils down to a truth about perforated things. This may well be right, assuming holes are perforations. But we still need an explicit theory of holes to do justice to the ordinary way of counting holes--or so says Cargle.

    The paper outlines a model-theoretic framework for investigating and comparing a variety of mereotopological theories. In the first part we consider different ways of characterizing a mereotopology with respect to (i) the intended interpretation of the connection primitive, and (ii) the composition of the admissible domains of quantification (e.g., whether or not they include boundary elements). The second part extends this study by considering two further dimensions along which different patterns of topological connection can be classified - the strength of (...)

    In ‘Towards a Solution to the Sorites Paradox’, Graham Priest gives us a new account of the sorites based on fuzzy logic. The novelty lies in the suggestion that truth-value assignments should themselves be treated as fuzzy objects, i.e., objects about which we can make fuzzy identity statements. I argue that Priest’s solution does not have the explanatory force that Priest advocates. That is, it does not explain why we find the existence of a cut-off point counter-intuitive. I also argue (...)

    R. Sorensen’s argument to the effect that ’vague’ is a vague predicate has been used by D. Hyde to infer that vague predicates suffer from higher-order vagueness. M. Tye has objected (convincingly) that this is too strong: all that follows from Sorensen’s result is that there are some border border cases, but not necessarily border border cases of every vague predicate. I argue that this is still too strong: Sorensen’s proof presupposes the existence of border border cases, hence cannot be (...)

    Standard lore has it that a proper name is a temporally rigid designator. It picks out the same entity at every time at which it picks out an entity at all. If the entity in question is an enduring continuant then we know what this means, though we are also stuck with a host of metaphysical puzzles concerning endurance itself. If the entity in question is a perdurant then the rigidity claim is trivial, though one is left wondering how it (...)

    The history of evolution is a history of development from less to more complex organisms. This growth in complexity of organisms goes hand in hand with a concurrent growth in complexity of environments and of organism-environment relations. It is a concern with this latter aspect of evolutionary development that motivates the present paper. We begin by outlining a theory of organism-environment relations. We then show that the theory can be applied to a range of different sorts of cases, both biological (...)

    One logic or many? I say--many. Or rather, I say there is one logic for each way of specifying the class of all possible circumstances, or models, i.e., all ways of interpreting a given language. But because there is no unique way of doing this, I say there is no unique logic except in a relative sense. Indeed, given any two competing logical theories T1 and T2 (in the same language) one could always consider their common core, T, and settle (...)

    We propose the beginnings of a general theory of environments, of the parts or regions of space in which organisms live and move. We draw on two sources: on the one hand on recent work on the ontology of space; and on the other hand on work by ecological scientists on concepts such as territory, habitat, and niche. An environment is in first approximation a volume of space; it is a specific habitat, location, or site that is suitable or adequate (...)

First I show how to interpret modal talk extensionally within the theory of modal occurrents. Then I show that the assumption that worlds be pairwise discrete is all that is needed to reconstruct the bulk of counterpart theory (i.e., to define the concept of a counterpart (...)

    Some have argued that the vagueness exhibited by geographic names and descriptions such as ''Albuquerque,'' ''the Outback,'' or ''Mount Everest'' is ultimately ontological: these terms are vague because they refer to vague objects , objects with fuzzy boundaries. I take the opposite stand and hold the view that geographic vagueness is exclusively semantic, or conceptual at large. There is no such thing as a vague mountain. Rather, there are many things where we conceive a mountain to be, each with its (...)

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.

    We argue that the ba­sic typology of spatial bound­aries involves an opposi­tion between bona fide (or physi­cal) boundaries on the one hand, and fiat bound­aries on the other, the latter being exemplified especially by boundaries induced through human demarcation, for example in the geographic realm. The classical metaphysical problems connected with the notions of adjacency, contact, separation and division can be resolved in an intuitive way by recognizing this two-sorted ontology of boundaries. Bona fide boundaries yield a notion of contact (...)

    Considering topology as an extension of mereology, this paper analyses topological variants of mereological essentialism (the thesis that an object could not have different parts than the ones it has). In particular, we examine de dicto and de re versions of two theses: (i) that an object cannot change its external connections (e.g., adjacent objects cannot be separated), and (ii) that an object cannot change its topological genus (e.g., a doughnut cannot turn into a sphere). Stronger forms of structural essentialism, (...)

    A plausible thought about vagueness is that it involves semantic incompleteness. To say that a predicate is vague is to say (at the very least) that its extension is incompletely specified. Where there is incomplete specification of extension there is indeterminacy, an indeterminacy between various ways in which the specification of the predicate might be completed or sharpened. In this paper we show that this idea is bound to founder by presenting an argument to the effect that there are vague (...)

    The ecological literature distinguishes between two ways of conceiving a “niche” (habitat, ecotope, biotope, microlandscape) [22, 39]. On the one hand, there is the traditional functional conception of a niche as the role or position enjoyed by an organism or population within an ecological community. As C. Elton [14] famously put it, “When an ecologist says ‘there goes a badger’ he should include in his thoughts some definite idea of the animal’s place in the community to which it belongs, just (...)

It should leave room for different types of boundaries, including both the bona fide boundaries which we find in (...)

    There are conflicting intuitions concerning the status of a boundary separating two adjacent entities (or two parts of the same entity). The boundary cannot belong to both things, for adjacency excludes overlap; and it cannot belong to neither, for nothing lies between two adjacent things. Yet how can the dilemma be avoided without assigning the boundary to one thing or the other at random? Some philosophers regard this as a reductio of the very notion of a boundary, which should accordingly (...)

    Material objects, such as tables and chairs, have an intimate relationship with space. They have to be somewhere. They must possess an address at which they are found. Under this aspect, they are in good company. Events, too, such as Caesar’s death and John’s buttering of the toast, and more elusive entities, such as the surface of the table, have an address, difficult as it may be to specify. A stronger notion presents itself, though. Some entities may not only be (...)

Specifically, in the first part we generalize the notion of an event structure to that of a refinement structure, where various degrees of temporal granularity are accommodated. In the second part we investigate how these structures can account for the context-dependence of temporal structures in natural language semantics.

This attitude is so natural and compelling that one is tempted to disregard the obvious difference between time periods and actual happenings in favor of the former: events become mere “intervals cum description”.1 On the other hand, in ordinary circumstances the point of talking about time is to talk about (...)

In the second part we focus on the latter and we give a refined formulation of our argument to the effect that the temporal dimension can be directly construed from a domain of events in terms of the basic mereotopological relations of parthood and boundary.

    In ‘Something to Do with Vagueness ...’, Linda Burns defends an analogy between the informational and the borderline-case variety of vagueness. She argues that the latter is in fact less extraordinary and less disastrous than people in the tradition of Michael Dummett and Crispin Wright have told us. However, her account involves presuppositions that cannot be taken for granted. Here is to take a closer look at some of these presuppositions and argue hat they may--when left unguarded--undermine much of Burns’ (...)

    Sarà capitato anche a voi, in treno, di cercare di aprire la porta tra un vagone e l’altro con l’espressivissima maniglia e, solo dopo non esserci riusciti, di aver notato il meno eloquente pulsante sulla destra. Il fenomeno non è troppo diverso da quando, non avendo capito qualcosa, chiediamo di farci un esempio. La convinzione —falsa—che parlare possa essere surrogato dall’indicare degli oggetti nasconde l’idea –vera– che gli oggetti parlino, e che alcuni parlino meglio di altri. Per capirlo, non c’è (...)

    Broadly understood, events are things that happen—things such as births and deaths, thunder and lightening, explosions, weddings, hiccups and hand-waves, dances, smiles, walks. Whether such things form a genuine metaphysical category is a question that has attracted the sustained interest of philosophers, especially in the second half of the 20th century. But there is little question that human perception, action, language, and thought manifest at least a prima facie commitment to entities of this sort: Pre-linguistic infants appear to be able (...)

Gran parte del nostro comportamento è descrivibile in termini spaziali: pianifi- chiamo azioni, cerchiamo di eseguirle secondo i nostri piani (eventualmente superando ostacoli imprevisti), ne controlliamo lo svolgimento attraverso (...)

    This original and enticing book provides a fresh, unifying perspective on many old and new logico-philosophical conundrums. Its basic thesis is that many concepts central in ordinary and philosophical discourse are inherently circular and thus cannot be fully understood as long as one remains within the confines of a standard theory of definitions. As an alternative, the authors develop a revision theory of definitions, which allows definitions to be circular without this giving rise to contradiction (but, at worst, to “vacuous” (...)

    Molti sistemi cognitivi, tra cui anche alcuni agenti artificiali, devono rappresentare lo spazio e gli oggetti spaziali per muoversi e agire in modo soddisfacente (per evitare un ostacolo, cogliere un frutto, decidere un punto dove atterrare). Nel caso degli esseri umani, la rappresentazione dello spazio ha anche un aspetto linguistico: sappiamo descrivere le relazioni spaziali o comprendere il significato di una preposizione come ‘tra’ immaginando una situazione spaziale cui essa si applichi. La rappresentazione dello spazio è pertanto un soggetto di (...)

    Il rapporto dei filosofi analitici con la metafisica è stato per lungo tempo difficile e conflittuale. In un certo senso, il movimento analitico venne inizialmente caratterizzandosi proprio in contrapposizione alla tradizione filosofica dominante dell’Ottocento, tutta assorta nell’impresa di rispondere a Kant attraverso rielaborazioni più o meno dogmatiche dell’idealismo critico. In una Cambridge in cui Bradley e McTaggart dominavano incontrastati, Moore non esitava ad accusare di miopia le teorie metafisiche «che pretendono di fornire un’agevole strada per superare le difficoltà che ostacolano (...)

    Una buona teoria semantica deve rendere conto del fatto che generalmente il significato di un’espressione complessa dipende dal significato delle parti. In particolare, il valore di verità di un enunciato composto dipende normalmente dal valore di verità degli enunciati che lo compongono e quindi, in ultima istanza, dal valore di verità di enunciati elementari, o «atomici». Tra questi il caso paradigmatico è costituito dagli enunciati in forma soggetto-predicato: (1) xèP, e, fortunatamente, le condizioni di verità di enunciati del genere appaiono (...)

Come ha mostrato Patrick Grim1, un rapido sguardo alla letteratura rivelerà una grande varietà di interpretazioni differenti dei termini di base e, conseguentemente, della LNC. In effetti, Grim identifica qualcosa come 240 diverse opzioni (con un conteggio prudente), e non credo occorra indugiare ulteriormente sulla combinatoria concettuale che si nasconde dietro questo comune frammento di terminologia logica.

    This is a detailed defense of the view that identity is not an eternal, necessary relation: things can be identical at one time and distinct at another; they can be identical in one world and distinct in another. The defense is judicial rather than passionate, as Gallois’s primary goal is to persuade the reader that the view is ‘at least as credible’ as its more fashionable alternatives.

Sin dall’antichità la teoria dell’argomentazione ha pertanto occupato una posizione di rilievo nella ricerca filosofica, e già a partire da Aristotele ha contribuito a definire quel settore disciplinare che oggi chiamiamo logica (dalla parola greca logos, che significa tra l’altro ‘discorso’, ‘ragionamento’). Aristotele stesso codificò la materia in maniera sistematica, (...)

  166. Achille Varzi, Logic and Metaphysics.
    As a theory of reasoning, logic has—or ought to have—nothing to do with metaphysics. It ought to have nothing to do with questions concerning what there is, or whether there is anything at all. It is precisely because of its metaphysical commitments that Aristotelian syllogistics, for example, was eventually deemed inadequate as a canon of pure logical reasoning. The inference from an A-form statement such as (1) All humans are mortal to the corresponding I-form statement.

    Sommario: La prima parte (sezioni 1– 3) introduce il tema: qual è il senso di una indagine ontologico-formale del cosiddetto mondo del senso comune? La seconda parte (sezioni 4–6) offre una prima analisi delle categorie e soprattutto delle strut- ture ontologiche su cui impostare tale indagine. Infine, la terza parte (sezione 7) offre spunti di sviluppo e accenna ad alcuni problemi aperti, vecchi e nuovi.

  168. Achille Varzi, Mereology.
    Mereology (from the Greek μερος, ‘part’) is the theory of parthood relations: of the relations of part to whole and the relations of part to part within a whole. Its roots can be traced back to the early days of philosophy, beginning with the Presocratic atomists and continuing throughout the writings of Plato (especially the Parmenides and the Thaetetus), Aristotle (especially the Metaphysics, but also the Physics, the Topics, and De partibus animalium ), and Boethius (especially In Ciceronis Topica ).

  169. Achille Varzi, Metafisica.
    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 significati corrispondono domini d’interesse specifici. (...)

Pochi giorni dopo la sua comparsa in libreria, nell’autunno del 19781, la New York Review of Books ne pubblicò una recensione a firma di W. V. O. Quine che non esitava a definirlo «una congerie».2 Si parla di stile, di teoria della citazione, di illusioni ottiche, (...)

Unfortunately, his mother is smarter than he expected. “I said we cannot be punished for something we have not done”, she says, “but certainly we can be punished for not having done something”.

  172. Achille Varzi, Ontologia: Dove Comincia E Dove Finisce.
    — Alla domanda «Che cosa esiste?» Quine rispondeva con un semplice «Tutto». Dire «tutto», però, equivale a dire nulla, a meno che non si forniscano indicazioni più dettagliate. Vogliamo sapere in che cosa consiste questo tutto, vogliamo un elenco dettagliato delle entità che vi rientrano, vogliamo una loro caratterizzazione. Il testo che segue cerca di fare il punto sulla possibilità di fornire queste indicazioni e chiarire in tal modo la questione ontologica senza avventurarsi in questioni metafisiche di portata più ampia.

    Le relazioni spaziali tra gli oggetti che ci circondano nel nostro microcosmo quotidiano o nel macroambiente delle posizioni geografiche e le proprietà spaziali di tali oggetti, come forma e dimensione, sono un soggetto di ricerca privilegiato per quei settori delle scienze cognitive che mirano a rappresentare fedelmente le competenze degli agenti umani. Gran parte del nostro comportamento è descrivibile in termini spaziali: pianifi- chiamo azioni, cerchiamo di eseguirle secondo i nostri piani (eventualmente superando ostacoli imprevisti), ne controlliamo lo svolgimento attraverso (...)

    Geography presents interesting and intricate trade-offs between empirical data and demands, on the one hand, and deep philosophical issues (from ontology to political philosophy), on the other. What is a geographic entity? What is the relationship between a geographic entity and a physical territory? Can a geographic entity survive without a territory or without definite borders? Can it survive radical changes in its territory? Are there clear-cut identity criteria for geographic categories? This paper serves as an introduction to a special (...)

  175. Achille Varzi, Parts, Wholes, and Part-Whole Relations: The Prospects of Mereotopology.
    We can see mereology as a theory of parthood and topology as a theory of wholeness. How can these be combined to obtain a unified theory of parts and wholes? This paper examines various non-equivalent ways of pursuing this task, with specific reference to its relevance to spatio-temporal reasoning. In particular, three main strategies are compared: (i) mereology and topology as two independent (though mutually related) chapters; (ii) mereology as a general theory subsuming topology; (iii) topology as a general theory (...)

  176. Achille Varzi, Supervaluationism and Paraconsistency.
    Since its first appearance in 1966, the notion of a supervaluation has been regarded by many as a powerful tool for dealing with semantic gaps. Only recently, however, applications to semantic gluts have also been considered. In previous work I proposed a general framework exploiting the intrinsic gap/glut duality. Here I also examine an alternative account where gaps and gluts are treated on a par: although they reflect opposite situations, the semantic upshot is the same in both cases--the value of (...)

  178. Achille Varzi, Spatial Entities.
    Ordinary reasoning about space--we argue--is first and foremost reasoning about things or events located in space. Accordingly, any theory concerned with the construction of a general model of our spatial competence must be grounded on a general account of the sort of entities that may enter into the scope of the theory. Moreover, on the methodological side the emphasis on spatial entities (as opposed to purely geometrical items such as points or regions) calls for a reexamination of the conceptual categories (...)

    The history of evolution is a history of development from less to more complex organisms. This growth in complexity of organisms goes hand in hand with a concurrent growth in complexity of environments and of organism-environment relations. It is a concern with this latter aspect of evolutionary development that motivates the present paper. We develop a formal theory of organism-environment relations and we show that the theory can be applied to a range of different sorts of cases, both biological and (...)

  182. Achille Varzi, Truth and Circular Definitions.
    This original and enticing book provides a fresh, unifying perspective on many old and new logico-philosophical conundrums. Its basic thesis is that many concepts central in ordinary and philosophical discourse are inherently circular and thus cannot be fully understood as long as one remains within the confines of a standard theory of definitions. As an alternative, the authors develop a revision theory of definitions, which allows definitions to be circular without this giving rise to contradiction (but, at worst, to “vacuous” (...)

    Temporal reference in natural language is inherently context dependent: what counts as a moment in one context may be structurally analysed in another context, and vice versa. In this note we show how the mereotopological apparatus developed elsewhere allows one to account for this phenomenon within the framework of event-based semantics.

    A b s t r a c t . This paper presents the outline of a formal ontology of contexts. More specifically, it deals with the ontology of ecological contexts (niches, habitats, environments, ambients) and of the relations between organisms, niches, and the spatial regions they occupy. The first part sets out the basic conceptual background. The second part outlines a semi-formal theory which builds upon notions and principles of mereology, topology, and the theory of spatial location.

Then let’s see what sort of things there must be in order for what we truthfully say to be true. Do we want to see whether x is distinct from y? Then let’s see whether there is any statement that is true of x but not of y. And so on. In this paper I (...)

    There are two main ways, philosophically, of characterizing the business of ontology, and it is good practice to try and keep them separate. On one account, made popular by Quine, ontology is concerned with the question of what there is. Since to say that there are things that are not would be selfcontradictory, Quine famously pronounced that such a question can be answered in a single word—‘Everything’. However, to say ‘Everything’ is to say nothing. It is merely to say that (...)

There are studies devoted to the description of events in language and to their representation in the brain. There are also metapsychological studies aimed at assessing the nature of mental events or the grounding of intentional action. Outside psychology, the notion of an event plays a prominent role in various areas of (...)

    Fictionalism in ontology is a mixed bag. Here I focus on three main variants—which I label after the names of Pascal, Berkeley, and Hume—and consider their relative strengths and weaknesses with special reference to the ontology that comes with common sense. The first variant is just a version of the epistemic Wager, applied across the board. For all we know—says the Pascalian—our ordinary common-sense ontology may be a fiction. However, what goes on in that fiction matters a lot to us. (...)

    Abstract. As a general theory of reasoning—and as a general theory of what holds true under every possible circumstance—logic is supposed to be ontologically neutral. It ought to have nothing to do with questions concerning what there is, or whether there is anything at all. It is for this reason that traditional Aristotelian logic, with its tacit existential presuppositions, was eventually deemed inadequate as a canon of pure logic. And it is for this reason that modern quantification theory, too, with (...)
