We regularly talk of the experience of time passing. Some theorists have taken the supposed phenomenology of time passing to provide support for metaphysical accounts of the nature of time; opposing theorists typically granted that there is a phenomenology of time passing while seeking to dispute that any metaphysical conclusions about time can be drawn from this. In recent debates theorists have also begun to dispute that there is a phenomenology of time passing – plausibly, if there is not, then (...) there is no relevant experience to be explained away, or for metaphysical conclusions to be drawn from. In the present paper I offer one explanation of why such disputes about the experience of time passing may seem intractable. However, I suggest that there is a distinct and more tractable issue lurking in this area, concerning our experience of how certain phenomena persist over time. Interestingly, articulating how we experience different phenomena as persisting over time doesn't simply provide a challenge to one metaphysical view of persistence rather than another; instead, it generates an explanatory challenge for a variety of competing views of persistence and, by extension, a challenge for popular combinations of views of the metaphysics of persistence and of time.

Este trabajo examina si la pregunta “¿puede pensar una máquina?” ha sido respondida de manera satisfactoria. La primera sección, justamente, examina el dictum cartesiano según el cual una máquina no puede pensar en principio. La segunda trata sobre una rebelión en contra de Descartes, encabezada por Babbage. A su vez, la tercera describe una segunda rebelión encabezada por Turing. En ambas se examina, primero el lenguaje mentalista/instrumentalista para describir a una máquina programada y segundo, el reemplazo de la pregunta por (...) el Juego de la Imitación. En la cuarta sección sostengo que la evidencia aportada por dicho juego nos devuelve a la pregunta, pese a Turing. Por último, la quinta sección versa sobre cómo la Habitación China de Searle, paradójicamente, apoya el dictum cartesiano, y lo hace porque tal experimento mental se basa en una capacidad mental falible: la introspección. Se concluye que la pregunta acerca de si puede pensar una máquina es derivada de otra pregunta filosófica compleja: la de la naturaleza de lo mental y el problema mente-cuerpo. (shrink)

Contemporary research in compositional, truth-conditional semantics often takes judgments of the relative unacceptability of certain phrasal combinations as evidence for lexical semantics. For example, observing that completely full sounds perfectly natural whereas completely tall does not has been used to motivate a distinction whereby the lexical entry for full but not for tall specifies a scalar endpoint. So far, such inferences seem unobjectionable. In general, however, applying this methodology can lead to dubious conclusions. For example, observing that slightly bent is (...) natural but slightly cheap is not (that is, not without a “too cheap” interpretation) leads researchers to suggest that the interpretation of bent involves a scalar minimum but cheap does not, contra intuition—after all, one would think that what is minimally cheap is (just) free. Such claims, found in sufficient abundance, raise the question of how we can support semantic theories that posit properties of entities that those entities appear to lack. This paper argues, using theories of adjectival scale structure as a test case, that the (un)acceptability data recruited in semantic explanations reveals properties of a two-stage system of semantic interpretation that can support divergences between our semantic and metaphysical intuitions.

A fundamental aspect of human cognition is the ability to parse our constantly unfolding experience into meaningful representations of dynamic events and to communicate about these events with others. How do we communicate about events we have experienced? Influential theories of language production assume that the formulation and articulation of a linguistic message is preceded by preverbal apprehension that captures core aspects of the event. Yet the nature of these preverbal event representations and the way they are mapped onto language (...) are currently not well understood. Here, we review recent evidence on the link between event conceptualization and language, focusing on two core aspects of event representation: event roles and event boundaries. Empirical evidence in both domains shows that the cognitive representation of events aligns with the way these aspects of events are encoded in language, providing support for the presence of deep homologies between linguistic and cognitive event structure.

Proportional quantification and progressive aspect interact in English in revealing ways. This paper investigates these interactions and draws conclusions about the semantics of the progressive and telicity. In the scope of the progressive, the proportion named by a proportionality quantifier (e.g. most in The software was detecting most errors) must hold in every subevent of the event so described, indicating that a predicate in the scope of the progressive is interpreted as an internally homogeneous activity. Such an activity interpretation is (...) argued to be available for telic predicates (e.g. cross the street) because these receive a partitive interpretation except in combination with a completive operator, which asserts that the event so described has culminated. The obligatoriness of the completive operator in the preterit is shown to parametrically distinguish those languages that show completion entailments in the preterit, e.g. English, from those that do not, e.g. Malagasy, Hindi, and Japanese.

A critical survey of the main philosophical theories about events and event talk, organized in three main sections: (i) Events and Other Categories (Events vs. Objects; Events vs. Facts; Events vs. Properties; Events vs. Times); (ii) Types of Events (Activities, Accomplishments, Achievements, and States; Static and Dynamic Events; Actions and Bodily Movements; Mental and Physical Events; Negative Events); (iii) Existence, Identity, and Indeterminacy.

Our aim in the present paper is to investigate, from the standpoint of truth-theoretic semantics, English tense, temporal designators and quantifiers, and other expressions we use to relate ourselves and other things to the temporal order. Truth-theoretic semantics provides a particularly illuminating standpoint from which to discuss issues about the semantics of tense, and their relation to thoughts at, and about, times. Tense, and temporal modifiers, contribute systematically to conditions under which sentences we utter are true or false. A Tarski-style (...) truth-theoretic semantics, by requiring explicitly represented truth conditions, helps to sharpen questions about the function of tense, and to deepen our insight into the contribution the tenses and temporal modifiers make to what we say by using them.

Ryle (1949, Chapter V) discusses a range of predicates which in different ways exemplify a property I shall call quasi-duality - they appear to report two actions or events in one predicate. Quasi-duality is the key property of predicates Ryle classed as achievements. Ryle's criteria for classification were not temporal or aspectual, and Vendler's subsequent adoption of the term achievement for the aktionsart of momentary events changes the term - Rylean achievements and Vendlerian achievements are in principle different classes. Nevertheless, (...) I shall argue in this paper that certain kinds of quasi-duality do have aspectual significance. This paper examines a number of quasi-dual predicates which are not generally discussed in the aktionsart literature, including break a promise, miscount, and cure the patient. Two types of quasi-dual predicates are identified and dubbed criterion predicates and causative upshot predicates. It is shown that both types of quasi-dual predicate lack process progressives, despite being durative, and it is argued that the lack of process progressives identifies these predicates as (aspectual) achievements. They are termed durative achievements to distinguish them from canonical, momentary achievements. It is argued that these predicates lack process progressives, and hence are achievements, because they express individual-level predicates on the event argument. A process progressive is stage-level for the event, and hence is incompatible with a predicate which is lexically individual-level for the event. (shrink)

There has been relatively little discussion, in contemporary philosophy of mind, of the active aspects of perceptual processes. This essay presents and offers some preliminary development of a view about what it is for an agent to watch a particular material object throughout a period of time. On this view, watching is a kind of perceptual activity distinguished by a distinctive epistemic role. The essay presents a puzzle about watching an object that arises through elementary reflection on the consequences of (...) two apparent truths about watching an object throughout a period of time. It proposes that the puzzle can be resolved by a view according to which for an agent to watch an object throughout a period of time is for that agent to maintain visual awareness of that object with the aim of perceptually knowing what that object is doing. The essay goes on to make some further suggestions about how the apparatus developed in connection with the notion of watching may enable us to offer related explanations of other kinds of perceptual activity. It proposes that a useful distinction can be drawn between perceptual activities like watching which have as their aim knowledge of what an object is doing and activities like looking or visually scrutinizing which have as their aims knowledge of the states or conditions of the objects of perceptual awareness.

The paper proposes a process-based model for an ontology that encompasses the emergence of process systems generated by increasingly complex levels of organization. Starting with a division of processes into those that are persistent and those that are fleeting, the model builds through a series of exclusive and exhaustive disjunctions. The crucial distinction is between those persistent and cohesive systems that are energy wells, and those that are far-from-equilibrium. The latter are necessarily open; they can persist only by interaction with (...) their environments. Further distinctions, developed by means of the notions of self-maintenance and error detection, lead to the identification of complex biological organisms that are flexible learners, some of which are self-conscious and form themselves into social institutions. This model provides a non-reductive model for understanding human beings as both embodied and yet emergent. In particular, it provides a way of characterizing action as ‘metaphysically deep’, not an ontological embarrassment within an otherwise physicalist world. (shrink)

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 on issues concerning aspectual phenomena, the (...) telicity/atelicity distinction, the treatment of statives, and temporal quantification.

There are languages – e.g., German, Inuktitut, andRussian – in which the aspectual reference of clausesdepends on the telicity of their event predicates. Weargue that in such languages, clauses or verb phrasesnot overtly marked for viewpoint aspect implicateor entail `event realization'', a property akin toParsons''s (1990) `culmination''. The aspectualreference associated with the use of clauses notovertly marked for aspect is computed in accordancewith the dependence of realization conditions ontelicity and in line with principles of Gricean pragmatics.We formalize event realization and (...) capture thetelicity-dependent patterns of aspectual reference onwhich it is based by combining Krifka''s (1989, 1992,1998) event lattices with a model-theoreticinterpretation of Klein''s (1994) theory of tense andaspect. The latter permits us to treat the `topic times''of aspectual operators as temporal constraints on event realization. (shrink)

The development of a defensible and fecund notion of emergence has been dogged by a number of threshold issues neatly highlighted in a recent paper by Jaegwon Kim. We argue that physicalist assumptions confuse and vitiate the whole project. In particular, his contention that emergence entails supervenience is contradicted by his own argument that the ‘microstructure’ of an object belongs to the whole object, not to its constituents. And his argument against the possibility of downward causation is question-begging and makes (...) false assumptions about causal sufficiency. We argue, on the contrary, for a rejection of the deeply entrenched assumption, shared by physicalists and Cartesians alike, that what basically exists are things (entities, substances). Our best physics tells us that there are no basic particulars, only fields in process. We need an ontology which gives priority to organization, which is inherently relational. Reflection upon the fact that all biological creatures are far-from-equilibrium systems, whose very persistence depend upon their interactions with their environment, reveals incoherence in the notion of an ‘emergence base’.

The goal of this piece is to put some pressure on Brian O’Shaughnessy’s claim that perceptual experiences are necessarily mental processes. The author targets two motivations behind the development of that view. First, O’Shaughnessy resorts to pure conceptual analysis to argue that perceptual experiences are processes. The author argues that this line of reasoning is inconclusive. Secondly, he repeatedly invokes a thought experiment concerning the total freeze of a subject’s experiential life. Even if this case is coherent, however, it does (...) not show that perceptual experiences are processes. (shrink)

Formal semantics constitutes the framework of this thesis, and the aim is to characterise the semantics of the progressive, as it appears in sentence. Max was running towards the station Among the problems is one known as the "imperfective paradox". According to intuitions, sentence entails, but no entailment holds between and. Max was running towards the station Max ran towards the station Max was running to the station Max ran to the station Since and would seem to have the same (...) logical form, they ought to have similar entailments. Why is this not so? This thesis is divided into two parts. The first part, containing chapters 2 to 5, evaluates the current formal theories that tackle the imperfective paradox. Solving the imperfective paradox consists of two tasks: the first is to characterise a semantic distinction between and, and the second is to supply a semantic analysis of the progressive that is sensitive to this distinction and so results in a solution to the imperfective paradox. According to how the current theories tackle these two tasks, they can be classified into three camps which I will name as follows: the Heterogeneous Strategy provides one approach for fulfilling the first task, the Eventual Outcome Strategy provides an approach for defining the semantics of the progressive, and the Event-based Strategy provides a further alternative for achieving the two tasks at hand. All these strategies are intuitively motivated, but we will argue that they are ultimately untenable. The Heterogeneous Strategy and the Event-based Strategy fail to mesh with the treatment of point adverbials such as "At 3pm", and the Eventual Outcome Strategy produces a definition of the progressive that is viciously circular. Thus although the current theories that tackle the imperfective paradox are highly intuitively motivated, we will ultimately show that the formulations of these intuitions give rise to conflicts and tensions when it comes to explaining the natural language data. The second part of the thesis, containing chapters 6 and 7, offers a new approach for tackling the imperfective paradox. This new approach invokes two tools; the interval-based temporal logic IQ, and Moens' event-based AI model of temporal reference. IQ is an interval-based temporal logic with several innovations. First, unlike the previous interval-based theories, IQ maintains a high level of homogeneity: an atomic sentence is true at an interval I only if it is true at all subintervals of I. Second, IQ offers a technique whereby temporal expressions can have representations that receive their semantic interpretation with respect to context. We use the roles of homogeneity and context in IQ to characterise the semantics of aspect, where the characterisation is based on Moens' model. This provides an arena in which to tackle the imperfective paradox anew. We explain the entailment between and, and at the same time explain why no entailment holds between and. Furthermore, we overcome the problems concerning the treatment of adverbials such as "At 3pm" that are encountered in the Heterogeneous Strategy and the Event-based Strategy, and, since we do not adopt the Eventual Outcome Strategy in defining the progressive, we overcome that strategy's problem of circularity. Hence our solution to the imperfective paradox will provide answers to the puzzles posed in the earlier chapters of the thesis. (shrink)

This paper explores the hypothesis that all comparative sentences— nominal, verbal, and adjectival—contain instances of a single morpheme that compositionally introduces degrees. This morpheme, sometimes pronounced much, semantically contributes a structure-preserving map from entities, events, or states, to their measures along various dimensions. A major goal of the paper is to argue that the differences in dimensionality observed across domains are a consequence of what is measured, as opposed to which expression introduces the measurement. The resulting theory has a number (...) of interesting properties. It characterizes the notion of ‘measurement’ uniformly across comparative constructions, in terms of non-trivial structure preservation. It unifies the distinctions between mass/count nouns and atelic/telic verb phrases with that between gradable and non-gradable adjectives. Finally, it affords a uniform characterization of semantically anomalous comparisons across categories. (shrink)

This book argues that a plausible account of emergence requires replacing the traditional assumption that what primarily exists are particular entities with generic processes. Traversing contemporary physics and issues of identity over time, it then proceeds to develop a metaphysical taxonomy of emergent entities and of the character of human life.

Logics of discrete time are, in Arthur Prior’s words, “applicable in limited fields of discourse in which we are concerned with what happens in a sequence of discrete states,” independent of “any serious metaphysical assumption that time is discrete.” This insight is applied to natural language semantics, a widespread assumption in which is that time is, as is the real line, dense. “Limited fields of discourse” are construed as finite sets of temporal propositions, inducing bounded notions of temporal granularity that (...) can be refined to expand the discourse. The construal is developed in line with Prior’s view of what is “metaphysically fundamental”. (shrink)

Claims concerning processes, claims of the form “xisφing”, have been the subject of renewed interest in recent years in the philosophy of action. However, this interest has frequently limited itself to noting certain formal features such claims have, and has not extended to a discussion of when they are true. This article argues that a claim of the form “xisφing” is true when what is happening withxis such that, if it is not interrupted, a φing will occur. It then applies (...) itself more directly to the case of action, arguing that when “xisφing” describesx's intentional action, it is true iffxis acting from a method she knows to be sufficient to φ, in the sense that if she is not interrupted in carrying out this method, she will φ. I use this criterion to argue that the carbon‐copier example Donald Davidson gives in “Intending” fails to refute Elizabeth Anscombe's claim that an agent who is φing intentionally knows that she is, because the agent in Davidson's example is not intentionally making the copies.

This paper is a critical examination of Vendler's well-known aspectual classes (states, activities, accomplishments, achievements). It is argued that it not classes that play a role in the explanation of aspectual phenomena but rather some specific semantic factors from which aspectual classes can be constructed, in particular factors inherent to the (lexical) verb and to the determiners of noun phrases.

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)

In theMetaphysics, Aristotle pointed out that some activities are engaged in for their own sake, while others are directed at some end. The test for distinguishing between them is to ask, ‘At any time during a period in which someone is Xing, is it also true that they have Xed?’ If both are true, the activity is being done for its own sake. If not, it is being done for the sake of some end other than itself. For example, if (...) I am thinking, it is true that I have thought. But if I’m making a blouse, it is not true that I have made a blouse, at least not this particular blouse. That’s not true until I have completed the project.There have been a number of attempts to deepen our understanding of this distinction. Anthony Kenny devoted a chapter of Action, Emotion, and Will to this issue, exploring the effect tense has on implication relations, and using that as a basis for dividing verbs of action into state-verbs, activity-verbs and performance-verbs. In more recent years the trend has been to generalize these categories so as to include occurrences other than actions, i.e., occurrences which do not involve intentions. While interest in this area tends to focus primarily on linguistic issues, such as the categorization of verbs, or on the logical analysis of sentences, there has been some interest in related metaphysical issues. In 1978 Alexander Mourelatos published ‘Events, Processes, and States,’ a paper which has turned out to be quite influential, in which he proposes an ontological trichotomy of occurrences. In his view, processes and events form distinct categories within the general category of occurrences. In this paper I will examine the reasoning underlying Mourelatos’s claim, arguing that the differences between processes and events cannot provide the basis for an ontological subcategorization of occurrences.

The distinction between telic and atelic predicates has been described in terms of the algebraic properties of their meaning since the early days of model-theoretic semantics. This perspective was inspired by Aristotle’s discussion of types of actions that do or do not take time to be completed1 which was taken up and turned into a linguistic discussion of action-denoting predicates by Vendler (1957). The algebraic notion that seemed to be most conducive to express the Aristotelian distinction appeared to be the (...) mereological notion of a part, applied to the time at which these predicates hold: atelic predicates, like push a cart, have the subinterval property, that is, whenever they are true at a time interval, then they are true at any part of that interval; this does not hold for telic predicates, like eat an apple, cf. Bennett & Partee (1972), Taylor (1977), and Dowty (1979)2. Bach (1986) integrated these insights into a semantics based on events. (shrink)

This paper explores the relationship between dynamic and truth conditional semantics for epistemic modals. It provides a generalization of a standard dynamic update semantics for modals. This new semantics derives a Kripke semantics for modals and a standard dynamic semantics for modals as special cases. The semantics allows for new characterizations of a variety of principles in modal logic, including the inconsistency of ‘p and might not p’. Finally, the semantics provides a construction procedure for transforming any truth conditional semantics (...) for modals into a dynamic semantics for modals with similar properties. (shrink)

There is a much-discussed form of argument the conclusion of which is that we do not directly perceive space-filling material objects themselves, only parts of their surfaces. Donald Davidson's view that events are temporal particulars invites a structurally similar argument about the direct perception of events. In this paper, I spell out such an argument and consider a number of possible solutions to it. I explore the idea that a satisfactory response to this problem in the philosophy of perception can (...) be grounded in a temporal ontology that includes temporal stuff as well as temporal particulars. I discuss different ways of developing this idea, and I go on to identify what I take to be the most promising version of an approach of this kind. (shrink)

A number of contemporary philosophers of mind have brought considerations from the study of aspect to bear on the ontological question how perceptual experiences persist over time. But, apart from rare exceptions, relatively little attention has been devoted to assess whether the way we talk about perceptual occurrences is of any relevance for discussions of ontological matters in general, let alone discussions about the ontological nature of perception. This piece examines whether considerations derived from the study of lexical aspect have (...) a significant bearing on what ontological views of perception we should endorse: I shall argue that such aspectual considerations are in fact of very little use for settling the relevant ontological issue.

In this paper we examine interactions of the reciprocal with distributive and collective operators, which are encoded by prefixes on verbs expressing the reciprocal relation: namely, the Czech distributive po and the collectivizing na-. The theoretical import of this study is two-fold. First, it contributes to our knowledge of how word-internal operators interact with phrasal syntax/semantics. Second, the prefixes po and na generate (a range of) readings of reciprocal sentences for which the Strongest Meaning Hypothesis (SMH) proposed by Dalrymple et (...) al. (1998) does not make the right predictions. The distributive prefix po prefers the Strong Reciprocity reading, although the SMH predicts that a weakening should take place, while with the prefix na we find cases where weaker reciprocal readings are preferable to the stronger ones predicted by the SMH. This behavior of po and na is, we propose, due to the way in which they modulate two factors that are crucial in the interpretation of reciprocal sentences: (i) the relevant subpluralities in the group denoted by the reciprocal's antecedent, and (ii) the strength of reciprocal relations. We provide a detailed analysis of the semantics of the prefixes po and na and their contribution to the meaning of reciprocal sentences within the general framework of event semantics with lattice structures.

This paper presents a diagnostic for identifying distributive constructions and shows that it applies to pseudopartitives and for -adverbials. On this basis, a unified account is proposed for the parallels between the constructions involved. This account explains why for -adverbials reject telic predicates (*run to the store for five hours), why pseudopartitives reject count nouns (*five pounds of book ), and why both reject certain measure functions like temperature and speed (*30 of water, *drive for 5 mph). These restrictions all (...) follow from a general constraint on distributive constructions. Related concepts such as the D operator (Link, 1987), the subinterval property (Bennett and Partee, 1972), and divisive reference (Cheng, 1973) can be understood as formalizing special cases of this constraint.
