Larry Horn is justifiably famous for his work on the semantics of the English conjunction or and both its relationship to the formal logic truth functions ∨ and @ (“inclusive” and “exclusive” disjunction respectively1) and its relationship to the ways people employ or in natural discourse. These interests have been present since his 1972 dissertation, where he argued for a “scalar implicature-based” account of many of these relationships as opposed to a presuppositional account. They have surfaced in his “Greek Grice” (...) paper (Horn 1973) as well as in his Negation book (Horn 1989) and his recent “Border Wars” paper (Horn, forthcoming) where he defends the position that there are two types of implicatures at work here: Q- implicatures based on Grice’s first maxim of Quantity (“Say Enough”) and R-implicatures based on Grice’s second maxim of Quantity (“Don’t Say Too Much”). In a nutshell, the idea is that when a speaker employs a sentence with a disjunction, the meaning (that is, the semantic value) of the or is inclusive. With careful and judicious use of the Q- and R-implicatures, Larry’s theory allows the hearer (often) to infer that the speaker wanted to convey an exclusive disjunction. (shrink)

Investigates the roles of temporal concepts and self-consciousness in the development of episodic memory. According to some theorists, types of long-term memory differ primarily in the degree to which they involve or are associated with self-consciousness (although there may be no substantial differences in the kind of event information that they deliver). However, a known difficulty with this view is that it is not obvious what motivates introducing self-consciousness as the decisive factor in distinguishing between types of memory and what (...) role it is supposed to play in remembering. The authors argue that distinctions between different kinds of memory should be made initially on the basis of the ways in which they represent events. In particular, it is proposed that the way in which remembered events are located in time provides an important criterion for distinguishing between different types of memory. According to this view, if there is a link between memory development and self-consciousness, it is because some temporal concepts emerge developmentally only once certain self-conscious abilities are in place.

In this thesis, I examine the metaphysical debate between the A-theory and the B-theory of time, first by elaborating upon its proper characterization, and then by examining the sorts of evidence that are often thought to be germane to it. This debate, as I see it, is about whether or not time passes in any objective sense: the A-theory holds that it does, while the B-theory holds that it does not. I identify two opposing conceptions of time—that of the “time (...) of ordinary experience” on one hand, and that of “scientific time” on the other—and argue that the tension between them is the driving force behind this debate. I then examine two aspects of “evidence” from the time of ordinary experience: the phenomenological experience of time and the linguistic experience of time. It is often supposed, by both A- and B-theorists alike, that these sorts of evidence lend credence to the A-theory of time, since ordinary experience suggests that time passes. I hope to discredit this presumption, and so challenge the very framework in which this debate is so often carried out. In particular, by closely examining both of these kinds of experience—phenomenological and linguistic—in turn, I hope to provide a partial argument to the effect that the ordinary experience of time as a whole does not favour the A-theory over the B-theory of time. In the case of the phenomenological evidence, this is because the A-theory is just as inconsistent with such evidence as is the B-theory of time; in the case of the linguistic evidence, this is because the B-theory is equally consistent with such evidence as is the A-theory of time, particularly once it is revealed that a certain key assumption is tacitly accepted by both sides of the debate. Because of the popularity of the claim that the ordinary experience of time favours the A-theory, I take this conclusion to be something of a modest defence for the B-theory of time. (shrink)

Mental files serve as individual or singular concepts. Like singular terms in the language, they refer, or are supposed to refer. What they refer to is not determined by properties which the subject takes the referent to have (i.e. by the information stored in the file), but through relations to various entities in the environment in which the file fulfills its function. Files are based on acquaintance relations, and the function of the file is to store whatever information is made (...) available through the relations in question. I offer a typology of files. The most important distinction is between proto-files and conceptual files. In contrast to proto-files, conceptual files can host not only information derived through the specific relation on which the file is based, but also information about the same object gained in some other way. In this framework identity comes into the picture twice. (i) Identity is presupposed when two pieces of information occur in the same file. Such 'presumptions of identity' ground the linguistic phenomenon of de jure coreference, which takes place when two singular terms, or two occurrences of a singular term, are associated with the same file. (ii) Judgments of identity work by linking two distinct files, thereby enabling information to flow freely between them. This corresponds to de facto coreference. (Linking is not merging ; identity judgments have the effect of merging files only when the files belong to a very specific category, that of 'encyclopedia entries' -- a type of conceptual file based on a higher-order relation rather than on a specific acquaintance relation.) In the last part of the paper I will discuss, and attempt to rebut, two objections to the mental-file account. According to the first objection, the account is circular ; according to the second objection, de jure coreference cannot be accounted for it in terms of identity of the associated mental files because de jure coreference is not a transitive relation.

In this paper it is shown how the DRT (Discourse Representation Theory) treatment of temporal anaphora can be formalized within a version of Montague Semantics that is based on classical type logic.

Theories of language in the twentieth century tend towards one of two radically different models. One paradigm holds that expressions ‘stand for’ entities and their meanings are the entities stood for by them. According to the other, expressions are rather tools of interaction and their meanings are their functions within the interaction, their aptitudes to serve it in their distinctive ways.

This thesis deals with the phenomenon of attitude reporting. More specifically, it provides a unified semantics of de re and de se belief reports. After arguing that de se belief is best thought of as a special case of de re belief, I examine whether we can extend this unification to the realm of belief reports. I show how, despite very promising first steps, previous attempts in this direction ultimately fail with respect to some relatively recent linguistic data involving quantified (...) and infinitival reports, logophoric constructions, and monstrously shifted indexicals. Formalizing my idea of a contextual resolution of acquaintance relations in a dynamic framework, I arrive at an alternative analysis that handles all these data. (shrink)

The aim of this paper is show a global strategy for defining and connecting logical criteria. Three partial criteria are distinguished: transparency for expressions, topic neutrality for consequence relation, and universality for theories. A global criterion is suggested, and proved to be fulfilled by classical and intuionistic logic.

This dissertation offers new proposals, based on a philosophical appraisal of scientific findings, to address old philosophical problems regarding our immediate acquaintance with time. It focuses on two topics: our capacity to determine the length of intervals and our acquaintance with the present moment. A review of the relevant scientific findings concerning these topics grounds the main contributions of this dissertation. Thus, this study introduces to the philosophical literature an empirically adequate way to talk about how the mind represents time (...) at the most fundamental level. In order to account for our immediate acquaintance with the duration of intervals, a theoretical framework for classifying clocks is used to explain why the representational outputs of the circadian clock and the stopwatch have metric structure. A philosophical analysis of these outputs is proposed to classify them and explain their properties. With respect to our immediate acquaintance with the present, a novel two-phase model of the present is proposed. This model shows that there are two forms of acquaintance with the present, which has consequences for contemporary debates in the philosophy of time. (shrink)

Reichenbach's event, reference and speech times are interpreted semantically by stringing and superposing sets of temporal formulae, structured within regular languages. Notions of continuation branches and of inertia, bound (in a precise sense) by reference time, are developed and applied to the progressive and the perfect.

In English, [1e] occurs only in have got, but it is included here because of its importance in other languages. In Vedic Sanskrit and ancient Greek, for example, the perfect of many achievement predicates can be used to denote the result state. A good semantics of the perfect should therefore have something to say about it.

Both formal semantics and cognitive semantics are the source of important insights about language. By developing precise statements of the rules of meaning in fragmentary, abstract languages, formalists have been able to offer perspicuous accounts of how we might come to know such rules and use them to communicate with others. Conversely, by charting the overall landscape of interpretations, cognitivists have documented how closely interpretations draw on the commonsense knowledge that lets us make our way in the world. There is (...) no opposition between these insights. Sooner or later we will have a semantics that responds to both. However, developing such a semantics is profoundly difficult, because there are certain tensions to be overcome in reconciling the two perspectives. For one thing, the overall landscape of meaning does seem to be characterized by a much richer ontology and more dynamic categories than are exhibited by the fragments typically studied in the formal tradition. One sign of strain is the recent tendency to talk of “procedural”, “non-compositional”, or “computational” semantics, as in Hamm, Kamp and van Lambalgen 2006, hereafter HK&vL. We think such locutions can serve as useful reminders to keep semantics fixed on the central question of how language allows us to share information that some have and others need to get. However, there is some danger that formalists will merely by put off by an idea that, taken literally, may not be such a good one. In this short article, we want to explore and defend the traditional realist view attributed by HK&vL to Lewis among others. In fact, this view offers a well-developed, extremely straightforward and robust account of the relation between semantics and cognition. Moreover, while the realist view has ways of accommodating the representationalist insights of DRT (Lewis 1979; Thomason 1990; Stalnaker 1998), it remains unclear how “computational” semantics can account for the key data for the realist view: cases where we judge interlocutors to be ignorant about aspects of meaning in their native language (Kripke 1972; Putnam 1975; Stalnaker 1979; Williamson 1994)..

We examine how Frege’s contrast between identity judgments of the forms “a=a” vs. “a=b” would fare in the special case where ‘a’ and ‘b’ are complex mental representations, and ‘a’ stands for an introspected ‘I’-thought. We first argue that the Fregean treatment of I-thoughts entails that they are what we call “one-shot thoughts”: they can only be thought once. This has the surprising consequence that no instance of the “a=a” form of judgment in this specific case comes out true, let (...) alone a priori true. This further reinforces Glezakos’s objections against the set-up of Frege’s puzzle, while also raising what we think is an acute problem for Fregeans, insofar as I-thought (and indexical thinking more generally), understood in their way, turns out to be incompatible with some basic features of rationality.

Featured course on "Dynamic Semantics" at NASSLLI 2016. Day 4: Temporality. Abstract: Cross-linguistic evidence shows that temporal reference likewise involves context change. In every language, temporal reference is similar to top-level nominal reference, except that instead of updating or referring to top-ranked individuals, temporal grammatical systems update or refer to top-ranked temporal referents (events, states, or times). We discuss and compare temporal reference in two sample languages: tense-based English and tenseless aspect-based Mandarin.

An account of the development of temporal understanding is proposed which links such understanding with the development of episodic memory. We distinguish between different ways of representing time in terms of the kinds of temporal frameworks they involve. Distinctions are made between frameworks that are perspectival or nonperspectival and those that represent recurrent sequences or particular times. Even primitive temporal understanding integrates both perspectival and nonperspectival components. However, since early frameworks are event-based and localized, they are not yet sufficient for (...) episodic memory in that they do not enable the child to think of events as having occurred at particular points in time. We describe the emergence of new kinds of frameworks in terms of the development of temporal decentering. Two levels of temporal decentering are distinguished, with the higher level involving an appreciation of how event representations depend on one's temporal perspective. (shrink)

In this paper I argue that the clash of the Sellars’ two images is particularly acute in the case of time. In Time and the World Order Sellars seems embarked on a quest to locate manifest time in Minkowski spacetime. I suggest that he should have argued for the replacement of manifest time with the local, path-dependent time of the “scientific image”, just as he suggests that manifest objects must be replaced by their scientific counterparts.

In this article I defend the view that many central aspects of the semantics of tense are determined by independently-motivated principles of syntactic theory. I begin by decomposing tenses syntactically into a temporal ordering predicate (the true tense, on this approach) and two time-denoting arguments corresponding to covert a reference time (RT) argument and an eventuality time (ET) argument containing the verb phrase. Control theory accounts for the denotation of the RT argument, deriving the distinction between main clause and subordinate (...) clause tenses. The theory of covert movement is used to account for the independent/indexical interpretation of relative clause tenses, and for the correlation between independent tense interpretation and a de re construal of the relative clause. A theory of “past polarity”, based on traditional negative polarity theory, accounts both for the simultaneous “sequence of tense” construal of past tenses in subordinate clauses embedded within past tense contexts, and for the obligatory indexical/independent interpretation of present tense in a relative clause embedded within a past tense context. Combined with the copy theory of movement, the polarity theory also provides an account of the semantics of double access sentences, treating them as involving a special kind of reconstruction effect.

ignate remote or historical past, the perfect being furthermore restricted to events not witnessed by the speaker.3 In the intervening stage of Vedic Sanskrit, the past tenses show a complex mix of temporal, aspectual, and discourse functions. On top of that, Rigvedic retains the injunctive, a chameleon-like category of underspecified finite verbs whose many uses partly overlap with those of the past tenses. The present study of the Rigvedic system is offered as a preliminary step towards the reconstruction and theoretical (...) interpretation of this aspect-to-tense trajectory. (shrink)
