Ontology is the philosophical discipline which aims to understand how things in the world are divided into categories and how these categories are related together. This is exactly what information scientists aim for in creating structured, automated representations, called 'ontologies,' for managing information in fields such as science, government, industry, and healthcare. Currently, these systems are designed in a variety of different ways, so they cannot share data with one another. They are often idiosyncratically structured, accessible only to those who (...) created them, and unable to serve as inputs for automated reasoning. This volume shows, in a nontechnical way and using examples from medicine and biology, how the rigorous application of theories and insights from philosophical ontology can improve the ontologies upon which information management depends.

Recently, von Fintel (2001) and Gillies (2007) have argued that certain sequences of counterfactuals, namely reverse Sobel sequences, should motivate us to abandon standard truth conditional theories of counterfactuals for dynamic semantic theories. I argue that we can give a pragmatic account of our judgments about counterfactuals without giving up the standard semantics. In particular, I introduce a pragmatic principle governing assertability, and I use this principle to explain a variety of subtle data concerning reverse Sobel sequences.

The most common account of attitude reports is the relational analysis according towhich an attitude verb taking that-clause complements expresses a two-placerelation between agents and propositions and the that-clause acts as an expressionwhose function is to provide the propositional argument. I will argue that a closerexamination of a broader range of linguistic facts raises serious problems for thisanalysis and instead favours a Russellian `multiple relations analysis' (which hasgenerally been discarded because of its apparent obvious linguistic implausibility).The resulting account can be (...) given independent philosophical motivations within anintentionalist view of truth and predication.

Quantified expressions in natural language generally are taken to act like quantifiers in logic, which either range over entities that need to satisfy or not satisfy the predicate in order for the sentence to be true or otherwise are substitutional quantifiers. I will argue that there is a philosophically rather important class of quantified expressions in English that act quite differently, a class that includes something, nothing, and several things. In addition to expressing quantification, such expressions act like nominalizations, introducing (...) a new domain of objects that would not have been present in the semantic structure of the sentence otherwise. The entities those expressions introduce are of just the same sort as those that certain ordinary nominalizations refer to (such as John's wisdom or John's belief that S), namely they are tropes or entities related to tropes. Analysing certain quantifiers as nominalizing quantifiers will shed a new light on philosophical issues such as the status of properties and the nature of propositional attitudes. (shrink)

This papers argues that the apparent constraint of adverbials like 'for two hours' (or 'throughout the house') should not be viewed as a restriction to telic events or event predicates, but should be explained entirely in terms of the quantificational status of such adverials, acting as quantifiers over (contextually individuated) parts of a time interval (or spatial region).

Possible worlds semantics faces a range of difficulties for at least certain types of modals, especially deontic modals with their distinction between heavy and light permissions and obligations. This paper outlines a new semantics of modals that aims to overcome some of those difficulties. The semantics is based on an a novel ontology of modal objects, entities like obligations, permissions, needs, as well as epistemic states, abilities, and essences. Moreover, it is based on truthmaking, in the sense of Fine’s recent (...) truthmaker semantics. (shrink)

The conception of truth-making, albeit in a rudimentary form, could already be discerned in the writings of G. E. Moore and E. Husserl in the early 1900s. A few years later it was more extensively exploited by William James. It was Wittgenstein, however, who gave the concept a precise meaning. In 1913/1914 Wittgenstein advanced a theory of possible worlds, only one of which was real. Every proposition suggests a part of a possible world which does or does not correspond to (...) parts of the real world. In the first case the proposition is true, in the second case false. Moreover, the part of the real world makes the sentence true. This part is a truth-maker, and the sentence is a truth-bearer. Surprisingly enough, Wittgenstein’s concept of truth-making had its family resemblance with William James’s conception of truth. In 1915 Wittgenstein stopped using the concept of truth-making—it was also not men-tioned in the Tractatus. Unfortunately, Russell did not notice this and in 1918 he adopted the concept of truth-making. In the 1930s, it was used by some second generation analytic philosophers (Schlick, Stebbing, and Wisdom). However, it became rather popular among analytic philosophers only in the 1980s. (shrink)

This paper aims to clarify the connection between the logic of temporal distinctions and the temporal features of propositions. Contra Prior, it argues that the adoption of tense operators does not commit one to the view that propositions can change their truth value over time.

Many claims about conceptual matters are often represented as, or inferred from, claims about the meaning, reference, or mastery, of words. But sometimes this has led to treating conceptual analysis as though it were nothing but linguistic analysis. We canvass the most promising justifications for moving from linguistic premises to substantive conclusions. We show that these justifications fail and argue against current practice (in metaethics and elsewhere), which confuses an investigation of a word’s meaning, reference, or competence conditions with an (...) analysis of some concept or property associated with that word.

Much previous work in artificial intelligence has neglected representing time in all its complexity. In particular, it has neglected continuous change and the indeterminacy of the future. To rectify this, I have developed a first‐order temporal logic, in which it is possible to name and prove things about facts, events, plans, and world histories. In particular, the logic provides analyses of causality, continuous change in quantities, the persistence of facts (the frame problem), and the relationship between tasks and actions. It (...) may be possible to implement a temporal‐inference machine based on this logic, which keeps track of several “maps” of a time line, one per possible history. (shrink)

When Booth moved his finger, thereby firing a gun, thereby killing Lincoln, did he perform three discrete actions, or were there relations of identity or inclusion among them? Most treatments of this problem have tended to assume there is but one sort of entity properly to be called an action, and hence that one answer to this question must be established to the exclusion of all others. And the favored answer has been that Booth's actions are not discrete, or indeed (...) even overlapping, but identical. It is possible, however, to adopt a more conciliatory spirit, in which a place is sought for talk of discrete or fine-grained actions in cases like this, as well as for entities of the coarser sort most have favored.

A persistent complaint about modal forms of the ontological argument is that the characteristic modalized existence assumptions of these arguments are simply too close to the conclusion to be of much probative value in establish­ing it. I present an abstract form of the ontological argument in which the properties imputed to the divine nature by these assumptions are replaced by any of a wide class of properties of a sort I call “actualizing.” These include basic theistic attributes such as authorship, (...) sovereignty and omniscience. The import of these arguments is to show that the metaphysical coherence of some of the most familiar conceptions of the divine nature ensures their actual realization. (shrink)

We develop a framework for natural language semantics which handles intensionality via metalogical constructions and deals with degree truth values in an integrated way. We take an axiomatic set theory, ZF, as the foundation for semantic representations, but we make ZF a metalanguage for part of itself by embedding a language ℒ within ZF which is basically a copy of the part of ZF consisting of set expressions. This metalogical set-up is used for handling propositional attitude verbs (limited to believe (...) in this paper). We define a truth function τ which determines the truth value τ(p, T) of an ℒ-proposition p with respect to a theory T. Theories are sets of ℒ-propositions with associated truth values, and can be viewed as a (much more well-defined) replacement for possible worlds. We develop a mechanism for defining belief worlds as theories. We simultaneously develop two different versions of our system - a Boolean version where the set Ω of truth values is {0, 1}, and a degree-truth version where Ω is the interval [0, 1] of real numbers. We use degrees of truth in handling a broad class of semantic predicates that we call base-focus predicates, which include generalized quantifiers as well as many adverb and adjective senses and certain discourse-level predicates.

When we talk about creation, we use the progressive and verbs of creation as in ‘Mary is building a house’. The modal account of the progressive says that a sentence such as ‘Mary is building a house’ is true just in case Mary eventually builds a house in all worlds in which her house-building proceeds normally. Recently, the modal account has come under fire from those who claim that it over-generates modal entailments and those who think the progressive should be (...) treated as a predicate of events. By properly situating the modal account within a contemporary semantic framework for natural language modals, I argue that it gives the best semantic treatment of the progressive. (shrink)

Accounts of ability in the philosophical literature have tended to be modal ones: claims about an agent’s abilities are understood in terms of what she does in certain non-actual scenarios. In contrast, a prominent account of ability ascriptions in the recent semantics literature appeals to genericity: claims about an agent’s abilities are understood in terms of what she generally manages to do. The latter account resolves some long-standing problems for modal accounts, but encounters problems of its own. I propose a (...) hybrid view, on which ability involves both a modal and a generic element. (shrink)

This book's purpose is to detail the anatomy of linguistic meaning, showing how the various elements of meaning fit together. part 1 defends the truth-theoretic conception of semantics, taking the notion of a sentence's truth-condition as the core of meaning. part 2 explores the complex interconnections between syntax, semantics and various pragmatic notions and attempts to reconcile the apparent differences between natural and formal language. part 3 examines the relation between semantics and psychology.

In this paper, we outline an approach to giving extensional truth-theoretic semantics for what have traditionally been seen as opaque sentential contexts. We outline an approach to providing a compositional truth-theoretic semantics for opaque contexts which does not require quantifying over intensional entities of any kind, and meets standard objections to such accounts. The account we present aims to meet the following desiderata on a semantic theory T for opaque contexts: (D1) T can be formulated in a first-order extensional language; (...) (D2) T does not require quantification over intensional entities­i.e., meanings, propositions, properties, relations, or the like­in its treatment of opaque contexts; (D3) T captures the entailment relations that hold in virtue of form between sentences in the language for which it is a theory; (D4) T has a finite number of axioms. If the approach outlined here is correct, it resolves a longstanding complex of problems in metaphysics, the philosophy of mind and the philosophy of language. (shrink)

This is a review of Kathrin Gluer's Donald Davidson: A Short Introduction. A dispute about the grounding of the Principle of Charity is discussed, and some resources Davidson has for responding to a criticism of his theory of action.

This paper offers an analysis of the logical form of plural action sentences that shows that collective actions so ascribed are a matter of all members of a group contributing to bringing some event about. It then uses this as the basis for a reductive account of the content of we-intentions according to which what distinguishes we-intentions from I-intentions is that we-intentions are directed about bringing it about that members of a group act in accordance with a shared plan.

This reviews, motivates, and extends the event analysis of action sentences and shows how it explains the compositionally of adverbial modification of action verbs and event verbs more generally. It includes a treatment of intensional adverbs like 'intentionally' and how it can be extended to the collective reading of plural action sentences.

In this paper, we argue that, omissions are not events or actions, but rather fact-like entities, and that, insofar as only events and actions can be causes, omissions cannot be causes. Nevertheless, since omissions can, and often do, play a role in the explanations of events, their place in such explanations must be found; and an attempt to find such a place is made.

A recent popular analysis of English indefinites isthat they involve a choice function mechanism in their semantic interpretation. However,there are diversified views regarding how intermediate scope readings should be dealt withand which level(s) existential closure should apply to. This paper attempts to make acontribution to this debate by examining existential polarity wh-phrases in Chinese. I showthat unlike the behaviors of polarity indefinites in St''át''imcets reported by Matthewson(1999), intermediate scope readings are possible for polarity wh-phrases in Chinese but aresubject to some (...) locality conditions. I suggest that implicit arguments of choice functionsmight have a parametric value the choice of which affects availability of intermediate readings.The findings in this paper thus revive the possibility, rejected by Matthewson (1999), that thechoice function mechanism may vary from language to language or from indefinite NPs in onelanguage to indefinite NPs in another language or even from one type of indefiniteNP to another type of indefinite NP within the same language.

This paper argues that superiority comparatives in Mandarin Chinese are all phrasal comparatives that can be directly interpreted, and makes a new suggestion of taking the bǐ-phrase (‘compare-phrase’) to be an adjunct and one constituent, but with bǐ-shells. This syntactic analysis allows one to combine into one phrase various compared constituents that would otherwise not be analyzed as forming a phrase by themselves. Semantically, in extension of work by Heim as well as Bhatt and Takahashi, bǐ is taken to compare (...) two sequences of arguments of a gradable predicate along the dimension given by that predicate. It is also suggested that comparatives across languages may be subject to three parameters: (i) argument-dependent comparison vs. non-argument dependent comparison, (ii) phrasal comparison vs. clausal comparison, and (iii) monoadic comparison vs. dyadic comparison.

This paper proposes an Interface Transparency Thesis concerning how linguistic meanings are related to the cognitive systems that are used to evaluate sentences for truth/falsity: a declarative sentence S is semantically associated with a canonical procedure for determining whether S is true; while this procedure need not be used as a verification strategy, competent speakers are biased towards strategies that directly reflect canonical specifications of truth conditions. Evidence in favor of this hypothesis comes from a psycholinguistic experiment examining adult judgments (...) concerning ‘Most of the dots are blue’. This sentence is true if and only if the number of blue dots exceeds the number of nonblue dots. But this leaves unsettled, e.g., how the second cardinality is specified for purposes of understanding and/or verification: via the nonblue things, given a restriction to the dots, as in ‘|{x: Dot(x) & ~Blue(x)}|’; via the blue things, given the same restriction, and subtraction from the number of dots, as in ‘|{x: Dot(x)}| – |{x: Dot(x) & Blue(x)}|’; or in some other way. Psycholinguistic evidence and psychophysical modeling support the second hypothesis. (shrink)

This article studies a type of comparative in Mandarin Chinese, which has rarely been discussed in the literature (Cheng 1966). I refer to them as Differential Verbal Comparatives (DVCs). I show that DVCs, unlike Chinese adjectival and adverbial comparatives, allow differentials that are definite DPs, for example, Jane Eyre he Pride and Prejudice ‘Jane Eyre and Pride and Prejudice’. Based on this fact and other empirical differences between DVCs and adjectival/adverbial comparatives in Mandarin Chinese, I motivate and develop a mapping-based (...) semantic analysis of DVCs and argue that this analysis fares better than a degree-based analysis.

The paper discusses the structure of non-verbal predication, with particular reference to the role of the copula. Differently from the main tenets of contemporary logico-philosophical and linguistic theories, a model of predication is proposed where the verbal component (specifically, tense information) is regarded as central in establishing the syntactic and semantic relation between a predicate and its subject. It is thus possible to recover some of the insights of the pre-Fregean analysis of predication. The proposed solution has a number of (...) significant consequences for the structure to be assigned to non-verbal predication, in particular for the semantics of small clause constituents, where the predication is established without the copula.

The development of analogical reasoning has traditionally been understood in terms of theories of adult competence. This approach emphasizes structured representations and structure mapping. In contrast, we argue that by taking a developmental perspective, analogical reasoning can be viewed as the product of a substantially different cognitive ability – relational priming. To illustrate this, we present a computational (here connectionist) account where analogy arises gradually as a by-product of pattern completion in a recurrent network. Initial exposure to a situation primes (...) a relation that can then be applied to a novel situation to make an analogy. Relations are represented as transformations between states. The network exhibits behaviors consistent with a broad range of key phenomena from the developmental literature, lending support to the appropriateness of this approach (using low-level cognitive mechanisms) for investigating a domain that has normally been the preserve of high-level models. Furthermore, we present an additional simulation that integrates the relational priming mechanism with deliberative controlled use of inhibition to demonstrate how the framework can be extended to complex analogical reasoning, such as the data from explicit mapping studies in the literature on adults. This account highlights how taking a developmental perspective constrains the theory construction and cognitive modeling processes in a way that differs substantially from that based purely on adult studies, and illustrates how a putative complex cognitive skill can emerge out of a simple mechanism.

Os demonstrativos foram considerados tradicionalmente como expressões referenciais. É o que encontramos na história da filosofia desde o início da tradição gramatical ocidental que sempre tratou os demonstrativos como pronomes. A maior provocação no livro de King consiste precisamente em romper com essa tradição ao apresentar os demonstrativos complexos (“esta mesa”, “aquele homem” etc.) como termos quantificados (e, portanto, termos não-referenciais). King apóia seu tratamento sobre exemplos escolhidos que parecem favorecer sua tese, como “aquele arquiteto que construiu essas pirâmides era (...) um gênio”, quando o locutor da frase não tem nenhum alvo referencial em mente e não pode apontar para ninguém no contexto da enunciação. Mostrarei: 1) que o tratamento de King representa uma tremenda ruptura com a tradição e desconsidera as intuições de gerações e gerações de lingüistas e filósofos da linguagem; 2) que King apóia sua tese em evidências de natureza puramente sintática sem discutir metodologicamente o peso que devemos atribuir a essas evidências sintáticas nas discussões de semântica; 3) que King não leva em conta todos os dados disponíveis, forçando os dados por ele recolhidos a entrar numa mesma teoria unificada, mas, para isso, paga um preço alto: uma redundância inaceitável na semântica das expressões demonstrativas simples.

This paper examines the task of understanding dialogues in terms of the mental states of the participating agents. We present a motivating example that clarifies the challenges this problem involves and then outline a theory of dialogue interpretation based on abductive inference of these unobserved beliefs and goals, incremental construction of explanations, and reliance on domain-independent knowledge. After this, we describe UMBRA, an implementation of the theory that embodies these assumptions. We report experiments with the system that demonstrate its ability (...) to accurately infer the conversants’ mental states even when some speech acts are unavailable. We conclude by reviewing related research on dialogue and discussing avenues for future study. (shrink)

In philosophical contexts, logical formalisms are often resorted to as a means to render the validity and invalidity of informal arguments formally transparent. Since Oliver and Massey , however, it has been recognized in the literature that identifying valid arguments is easier than identifying invalid ones. Still, any viable theory of adequate logical formalization should at least reliably identify valid arguments. This paper argues that accounts of logical formalization as developed by Blau and Brun do not meet that benchmark. The (...) paper ends by suggesting different strategies to remedy the problem.

Arguments from analogy are pervasive in everyday reasoning, mathematics, philosophy, and science. Informal logic studies everyday argumentation in ordinary language. A branch of fuzzy logic, approximate reasoning, seeks to model facets of everyday reasoning with vague concepts in ill-defined situations. Ways of combining the results from these fields will be suggested by introducing a new argumentation scheme—a fuzzy analogical argument from classification—with the associated critical questions. This will be motivated by a case study of analogical reasoning in the virtual friendship (...) debate within information ethics. The virtual friendship debate is a disagreement over whether virtual friendships are genuine friendships. It will be argued that the debate could move away from its current impasse, caused by unproductive metaphysical and logical assumptions, if extant arguments are reinterpreted as fuzzy analogical arguments from classification, and subjected to a new set of critical questions which would replace the quest for facts of essence about friendship with an emphasis on empirical data, persuasion, and definitional power.

Predicates like gather and ones like be numerous have both been described as ‘collective predicates,’ since they predicate something of a plurality. The two classes of predicates differ, however, with respect to plural quantifiers, which are grammatical with gather-type predicates but ungrammatical with numerous-type predicates. Here, I show that the gather/numerous opposition derives from mereological properties that are familiar from the domains of telicity and mass/count. I address problems of undergeneration and overgeneration with two technical innovations: first, I weaken the (...) property of divisibility to Champollion’s concept of stratified reference; second, I provide mechanisms to rule out accidental satisfaction of the logical property. More broadly, I place collective predication in a larger context by building empirical connections to mass/count and collectivity across semantic domains. (shrink)

This paper pursues some of the consequences of the idea that there are (at least) two sources for distributive/cumulative interpretations in English. One source is lexical pluralization: All predicative stems are born as plurals, as Manfred Krifka and Fred Landman have argued. Lexical pluralization should be available in any language and should not depend on the particular make-up of its DPs. I suggest that the other source of cumulative/distributive interpretations in English is directly provided by plural DPs. DPs with plural (...) agreement features can ‘release’ those features to pluralize adjacent verbal projections. If there is a lexical source for distributive/cumulative interpretations, there should be instances of such interpretations with singular DPs. But there should also be cases of distributive/cumulative interpretations that require the presence of DPs with plural agreement morphology. (shrink)

Along with many other languages, English has a relatively straightforward grammatical distinction between mass-occurrences of nouns and their countoccurrences. As the mass-count distinction, in my view, is best drawn between occurrences of expressions, rather than expressions themselves, it becomes important that there be some rule-governed way of classifying a given noun-occurrence into mass or count. The project of classifying noun-occurrences is the topic of Section II of this paper. Section III, the remainder of the paper, concerns the semantic differences between (...) nouns in their mass-occurrences and those in their count-occurrences. As both the name view and the mixed view are, in my opinion, subject to serious difficulties discussed in Section III.1,I defend a version of the predicate view. Traditionally, nouns in their singular count-occurrences are also analyzed as playing the semantic role of a predicate. How, then, does the predicate view preserve the intuitive difference between nouns in their mass- and those in their count-occurrences? I suggest, in Section III.2, that there are different kinds of predicates: mass-predicates, e.g. ‘is hair’, singular count-predicates, e.g. ‘is a hair’, and plural count-predicates, e.g. ‘are hairs’. Mass-predicates and count-predicates, in my view, are not reducible to each other. The remainder of Section III takes a closer look at the differences and interrelations between these different kinds of predicates. Mass-predicates and count-predicates differ from each other truth-conditionally, and these truth-conditional differences turn out to have interesting implications, in particular concerning the part-whole relation and our practices of counting. But mass- and count-predicates are also related to each other through systematic entailment relations; these entailment relations are examined in Section III.4. (shrink)
