Temporal Expressions

Este artículo propone recorrer las diferentes perspectivas desde las que históricamente se ha pensado la utopía. En este recorrido Miguel Abensour subraya dos giros fundamentales. El primero sería la asignación de la utopía al tiempo por medio de su transferencia a una ontología dialéctica, operación llevada a cabo por Marx e identificada por Marc Bloch. El segundo, aún más importante en cuanto se trata de una tarea presente, sería la superación de los límites que la previsión dialéctica impone a la (...) utopía a partir de un pensamiento de la alteridad, aspecto en el que la filosofía de Emmanuel Levinas juega un papel exploratorio pionero.  .

This article investigates aspectual meaning and its interaction with independently motivated temporal constraints imposed by coherence relations. I argue that aspectual markers denote functions from a set of events denoted by a verb-phrase (VP) to a set of VP-event parts that are located relative to (i) an input encoding explicitly temporal information and (ii) an input encoding information about discourse connectivity. By virtue of encoding information about discourse connectivity, aspectual makers play a nontrivial role in determining which coherence relation holds (...) between successive utterances and thereby constrain the ordering of eventualities described by these utterances. The core data that support these claims come from discourses containing the Russian imperfective. This aspect is remarkable because it can constrain the temporal location of different event parts. Depending on the event part that is constrained, the imperfective often leads to an inference that the described event precedes or overlaps a salient event previously mentioned in the discourse. I argue that the imperfective is rarely found in narrative contexts because its semantics rules the so-called OCCASION relation, which establishes a particular kind of contingency relationship between events. The proposed analysis accounts for the discourse properties of the Russian imperfective and is shown to be compatible with the modal properties of this aspect. I also show how the analysis could be extended to account for the meaning of the English progressive and temporal adverbials. (shrink)

This paper proposes that a core semantic property of temporal locating adverbs is the ability to introduce a new time discourse referent. The core data comes from that same day in narrative discourse. I argue that unlike other previously studied temporal locating adverbs—which introduce a new time discourse referent and relate it to the speech time or a salient time introduced into the discourse context—that same day is ‘twice anaphoric’, i.e. it retrieves two salient times from the input context without (...) introducing one of its own. Moreover, I argue that the adverb currently is like that same day in not introducing a new time discourse referent. Unlike that same day, however, currently has both a deictic and an anaphoric usage analogous to on Sunday. The analysis that I propose is implemented within Compositional Discourse Representation Theory. It illustrates how adverbial meaning can be integrated within a more general theory of temporal interpretation. (shrink)

In 1936, Benjamin Lee Whorf wrote a justly famous paper entitled "An American Indian Model of the Universe" (Carroll, 1956). In that paper, Whorf criticized the easy assumption that people in different cultures, speaking radically different languages, share common presuppositions about what the world is like. He contrasted the Hopi view of space and time with what he called elsewhere the Standard Average European view. For the Hopi, space and time are inherently relativistic; for the speaker of Western European languages, (...) like English, the universe is basically Newtonian, time and space are absolute, "containers" of things and events.

McTaggart's famous argument that the A-series is contradictory is vitiated by an unsatisfactory conceptualization of tenses which can be corrected by making explicit their relational structure. This leads into a much sharper formulation of his apparent contradiction, and defusing this apparent contradiction requires a careful distinction between tensed and tenseless descriptions of thoughts. As a result the ‘unreality’ of tense turns out to rest on the fact that tensed descriptions of temporal facts do not capture their identity. This ‘metaphysical’ priority (...) of tenseless over tensed descriptions of time is, however, counterbalanced by an ‘epistemological’ priority of tensed thoughts over tenseless thoughts: a conception of tense which requires a form of self-consciousness turns out to be an essential ingredient of rational thought.

By showing that tense references to times can be canonically paraphrased with the devices of predicate logic, this study provides evidence for the Quinean dictum that "to be is to be the value of a variable." ;It is argued that special tense operators, as used in tense logics and Montague grammars, are theoretically superfluous and betray an insensitivity to certain features of the linguistic data. Such alternative logics and formal grammars are compared with the theory of tense reference developed here, (...) and are judged less general, less simple, and less familiar. ;Two analyses of the progressive aspect--those of Goeffrey Leech, and of John Goldsmith and Erich Woisetschlaeger--are examined and criticized. Some characteristics of the use of the progressive aspect are described, but a complete theory is not offered. ;Restrictions governing the co-occurrence of temporal specifiers with the other tense forms are used in the discovery and testing of hypotheses about the structure of each of these forms. ;Criticisms are offered of the views of Arthur Prior and Stephen Braude on deixis in tense reference. It is also argued that the use of dummy predicates to represent the deictic and anaphoric elements of tense reference is both simpler and more adequate than the alternative recommended by Tyler Burge. ;A novel theory of the present perfect is advanced. It is motivated by observations of the co-occurrence, or lack thereof, of certain temporal specifiers with verbs in present perfect form. In turn, this theory explains the vague notions of "current relevance" and "indefinite past," which others have used to distinguish uses of the present perfect from uses of the simple past. ;Besides the standard idioms of predicate logic, the theory utilizes special predicates for 'is a time', 'is a part of', and 'is earlier than', and three metalinguistic dummy predicates. These dummy predicates hold place for identifying descriptions of a verb's base time, predicate satisfaction time, and reference time. Normally, these descriptions are deictically and anaphorically gleaned from the social, physical and linguistic context of utterance. Without these descriptions, a canonical representation of the tense structure of a sentence is incompletely interpreted. Nonetheless, it does exhibit all of the syntactic structure of the tense references in the sentence it represents. ;A Reichenbachian three-point theory of tense reference is adopted with significant modifications. It is shown that Reichenbach's "point of speech" need not be deictically identified and is better relabelled "base time." For additional reasons, Reichenbach's "point of reference" and "point of the event" are relabelled, respectively, "reference time" and "predicate satisfaction time." ;This study utilizes the idioms of first-order predicate logic to represent the referential structure of English verb tenses and of certain features of the progressive aspect. The primary purpose of the study is to explain the uses of each tense on the basis of an analysis of the temporal references characteristic of that tense. The study is intended as a contribution to applied logic, philosophy of logic, and linguistics. (shrink)

If you utter sentence ‘Obama was born in 1961’ now, you say something true about the past. Since the past will always be such that the year 1961 has the property of being a time in which Obama was born, it seems impossible that could ever be false in a future context of utterance. We shall consider the case of a sentence about the past exactly like , but which was true when uttered a few years ago and is no (...) longer true now. On this basis, we shall conclude that the past has changed. (shrink)

Shows that both anaphoricity and egocentric de se binding play a crucial role in the interpretation of tense in discourse. Uses the English backwards shifted reading of the past tense in a mistaken time scenario to bring out the tension between these two features. Provides a suitable representational framework for the observed clash in the form of an extension of DRT in which updates of the common ground are accompanied by updates of each relevant agent's complex attitudinal state.

The B-theory of time holds that McTaggart’s A-series of past, present, and future is reducible to the B-series of events running from earlier to later. According to the date-theory—originally put forth by J.J.C. Smart and later endorsed by by D.H. Mellor—the truth conditions of tensed or Asentence-tokens can be given in terms of tenseless or B-sentences and, therefore, A-sentence-tokens do not ascribe any A-determinations of pastness, presentness, or futurity. However, as Nathan Oaklander has argued, the date-theory does not provide an (...) adequate analysis of the ontological truth conditions of irreducible A-propositions. I show that the co-reporting theory—which holds that for every A-sentence-token there is a B-sentence that differs in sense but reports the same event or state of affairs—escapes the objections Oaklander has addressed against the date-theory.

Natural languages exhibit a great variety of verbal paradigms. For instance, in English main verbs are grammatically marked for tense, whereas in the tenseless Eskimo-Aleut language Kalaallisut they are marked for illocutionary mood. Although time is a universal dimension of the human experience and speaking is part of that experience, some languages encode discourse reference to time without any grammatical tense morphology (see e.g. Bittner 2005), or reference to speech acts without any illocutionary mood morphology.

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.

Unlike English and Polish, Mandarin has no grammatical tense (TNS). Therefore, reference times are only introduced by temporal modifiers (contra Smith 1991/7, Wu 2003, Lin 2005, etc). In Mandarin discourse, the frequency of such modifiers (‘today’, ‘last night’, etc) is about the same (low) as in tensed languages (e.g. English, Polish) and plays a similarly marginal role in temporal discourse reference. This, however, does NOT mean that in tenseless Mandarin temporal relations between eventualities in discourse are in any way less (...) precise than in tensed languages. Rather, the issue is HOW temporal relations are established: indirectly , via reference times, or directly, without mediating reference times. Tensed English and Polish typically first introduce a topic time (by topic-setting TNS) and then locate verbal eventualities in relation to this temporal topic (by anaphoric TNS). (shrink)

Last time we saw that grammatical tenses anaphorically refer to top-ranked times or time-valued functions of top-ranked events, just like grammatical person markers anaphorically refer to top-ranked individuals or invididual-valued functions of top-ranked events. Today we extend this idea to grammatical aspect. Specifically, grammatical aspect marking in English and Polish is analyzed as discourse anaphora to top-ranked eventualities (states or events).

This is part two of our discussion of discourses involving anaphora to and by quantificational expressions of various types. In part one (March 8), we focused on quantification over individuals ("Nominal quantification as top-level anaphora"). In part two (March 22-29), we show that the proposed analysis of quantification, as anaphoric discourse reference to top-ranked sets, automatically generalizes to temporal quantifiers (over times, events, or states).

Abstract According to an influential theory, English tenses are anaphoric to an aforementioned reference point. This point is sometimes construed as a time (e.g. Reichenbach 1947, Partee 1973, Stone 1997) and sometimes as an event (e.g. Kamp 1979, 1981, Webber 1988). Moreover, some researchers draw semantic parallels between tenses and pronouns (e.g. Partee 1973, 1984, Stone 1997), whereas others draw parallels between tenses and anaphorically anchored (in)definite descriptions (e.g. Webber 1988). This paper proposes a unified approach.

Simple Mandarin Chinese texts translated into Update with Centering. Notes toward a directly compositional fragment of Mandarin Chinese, combining Categorial Grammar with Update with Centering, to appear in Bittner (in prep.) "Temporality: Universals and Variation".

Natural languages exhibit a great variety of grammatical paradigms. For instance, in English verbs are grammatically marked for tense, whereas in the tenseless Eskimo-Aleut language Kalaallisut they are marked for illocutionary mood. Although time is a universal dimension of the human experience and speaking is part of that experience, some languages encode reference to time without any grammatical tense morphology, or reference to speech acts without any illocutionary mood morphology. Nevertheless, different grammatical systems are semantically parallel in certain respects. Specifically, (...) I propose that English tenses form a temporal centering system, which monitors and updates topic times, whereas Kalaallisut moods form a modal centering system, which monitors and updates modal discourse referents. To formalize these centering parallels I define a dynamic logic that represents not only changing information but also changing focus of attention in discourse (Update with Centering, formalizing Grosz et al 1995). Different languages can be translated into this typed logic by directly compositional universal rules of Combinatory Categorial Grammar (CCG) The resulting centering theory of tense and illocutionary mood draws semantic parallels across different grammatical systems. The centering generalizations span the extremes of the typological spectrum, so they are likely to be universal. In addition, the theory accounts for the translation equivalence of tense and illocutionary mood in a given utterance context. Following Stalnaker (1978) I assume that the very act of speaking up has a ‘commonplace effect’ on the context. It focuses attention on the speech act and thereby introduces default modal and temporal topics. These universal defaults complement language-specific grammars, e.g. English tenses and Kalaallisut moods. In a given utterance context the universal discourse-initial defaults plus language-specific grammatical marking may add up to the same truth conditions.. (shrink)

Day 1 of advanced course on "Temporal anaphora in tenseless languages" at 2006 ESSLLI.

I propose that Mandarin ｡-sentences (units marked by ｡) are aspectual topic-comment sequences, where an initial update (terminating in a pause) introduces a topic state for comment by one or more clauses. Each comment anaphorically refers to the topic state via the aspect feature of the verbal predicate. This proposal explains why Mandarin ｡-sentences have controversial boundaries, since speakers may disagree where one topic state ends and the next one begins. It also explains various manifestations of aspect-prominence and topic-prominence in (...) Mandarin discourse. In Bittner (2014), this proposal is formally implemented in Categorial Grammar and a new dynamic logic called Update with Centering. (shrink)

This book surveys the ways in which languages of different types refer to past, present, and future events and how these referents are related to the knowledge and attitudes of discourse participants. The book is the culmination of fifteen years of research by the author. Four major language types are examined in-depth: tense-based English, tense-aspect-based Polish, aspect-based Chinese, and mood-based Kalaallisut. Each contributes to a series of logical representation languages, which together define a common logical language that is argued to (...) underlie all language types. The four types differ in whether they choose to grammaticalize discourse reference to times (tense), events (aspect), and/or attitudes (mood), and how non-grammaticalized elements are inferred. The common logical language is a dynamic update logic, building on DRT and Centering Theory, but with a novel architecture—e.g. the distinction between focal vs. peripheral attention plays a key role, parallel to focal vs. peripheral vision.

In English, discourse reference to time involves grammatical tenses interpreted as temporal anaphors. Recently, it has been argued that conditionals involve modal discourse anaphora expressed by a parallel grammatical system of anaphoric modals. Based on evidence from Kalaallisut, this paper argues that temporal and modal anaphora can be just as precise in a language that does not have either grammatical category. Instead, temporal anaphora directly targets eventualities of verbs, without mediating tenses, while modal anaphora involves anaphoric moods and/or attitudinal verbs.

It has long been recognized that temporal anaphora in French and English depends on the aspectual distinction between events and states. For example, temporal location as well as temporal update depends on the aspectual type. This paper presents a general theory of aspect-based temporal anaphora, which extends from languages with grammatical tenses (like French and English) to tenseless languages (e.g. Kalaallisut). This theory also extends to additional aspect-dependent phenomena and to non-atomic aspectual types, processes and habits, which license anaphora to (...) proper atomic parts (cf. nominal pluralities and kinds).

This paper introduces a framework for direct surface composition by online update. The surface string is interpreted as is, with each morpheme in turn updating the input state of information and attention. A formal representation language, Logic of Centering, is defined and some crosslinguistic constraints on lexical meanings and compositional operations are formulated.

The Eskimo language Kalaallisut (alias West Greenlandic) has traditionally been described as having a rich tense system, with three future tenses (Kleinschmidt 1851, Bergsland 1955, Fortescue 1984) and possibly four past tenses (Fortescue 1984). Recently however, Shaer (2003) has challenged these traditional claims, arguing that Kalaallisut is in fact tenseless.

Last time we introduced the notion of an illocutionary perspective . The basic idea is that the very act of speaking up introduces several discourse referents. The speech act itself (e ) is introduced as the central perspective point ( ε ). In addition, all the speech spheres (p ) where this speech act is realized, as well as the worlds of each sphere (w ∈p ) are introduced as modal topics ( Ω and  ω ).

In this paper, I analyze the verbal suffix -uŋil in Washo as an optional past tense. It is optional in the sense that it is not part of a paradigm of tenses, and morphologically tenseless clauses are also compatible with past time reference. Specifically, I claim that -uŋil is the morphological exponent of a tense feature [past], which presupposes that the reference time of the clause, denoted by a temporal pronoun, precedes the evaluation time. Meanwhile, morphologically tenseless clauses lack a (...) semantic tense restricting the value of the reference time pronoun. In comparing this analysis with one containing a covert non-future tense in morphologically tenseless clauses, I show that the range of empirical contexts that distinguish these analyses is quite narrow. However, I offer a novel argument against a covert tense analysis based on the lack of Maximize Presupposition effects. Crucially, the fact that -uŋil does not form a paradigm of tenses results in a failure for Maximize Presupposition to apply. The proposed analysis places cross-linguistic variation at the level of the paradigm of tense features, namely whether they are present or absent, and if present, whether obligatorily so. This case study from Washo thus reveals what a language where tense features are optional can look like, and more generally contributes to the growing body of literature on cross-linguistic semantics devoted to uncovering the ways in which temporal interpretation can be achieved in natural language.

unified treatment of both (families of) interpretations is based on a revised notion of settledness. The main features of this approach are the following: (i) in branching structures, a world can be represented not by a single course of events, but by a node u in the tree, where u itself is seen as the cluster of courses of events passing through it; (ii) the utterance time is uniquely fixed; (iii) the utterance world is not uniquely fixed; (iv) because of (...) (iii), an utterance-event is associated not to a single context, but to a plurality of contexts, depending on which world we are considering as the utterance world. As a consequence, if a future-tensed sentence φ is uttered at u and its truth (falsehood) is already a settled issue at u itself, then the sentence is true (false) at u; otherwise the sentence is neither true nor false at u and, to get a definite truth value, we must wait until settledness is reached in a different context. Since what is crucial, in both cases, is the reference to a given state of information, such a treatment can be extended to other intriguing uses of the future tense, starting from the epistemic reading. These uses will be topic of a related paper. (shrink)

According to the actualist view, what is essential in the truth conditions of a future-tensed sentence of type ‘it will be the case that ϕ’ is the reference to the unique course of events that will become actual. On the other hand, the modal view has it that the truth conditions of such a sentence require the truth of ϕ being already “settled” at the time of utterance, where “being settled” is defined by universal quantification over a domain of courses (...) of events, the futures compatible with what has happened up to the time of utterance. On the proposal we discuss in this paper, actualism and modalism are seen as two related attitudes that speakers can have when evaluating future-tensed sentences, and the corresponding interpretations undergo a unified semantic treatment based on a contextual notion of settledness. A central feature of our approach is a dynamic view of contexts of utterance, according to which the world of the utterance is not fixed once and for all, as different worlds, by the passing of time, can play this role in turn. Finally, one major goal of the paper is to show how the unified analysis we propose accounts for a particularly interesting interpretation of futuretensed sentences, often referred to as ‘epistemic reading’.

The original evidence advanced to support the Tensed S Condition (TSC) and the Specified Subject Condition (SSC) in Chomsky's Conditions on Transformations is reconsidered and viable alternatives to these constraints are provided. It is shown that TSC and SSC, in some instances, lead to a loss of linguistically significant generalization. Satisfactory alternatives can account for the relevant range of data and provide a more general account of additional data. Finally, counterevidence to Subjacency and Superiority is adduced, but explicit alternatives to (...) these conditions are not offered. (shrink)

We have seen that we cannot de-tense a sentence like (15) simply by changing its verb, since the tense of such a sentence is determined by a temporal adverb. More importantly, we have seen that de-tensing is a process of removing certain temporal restrictions from the truth-conditions of tensed sentences, and that tensed and tenseless forms of a verb do not differ in sense. Once we understand this, and once we realize that it is an historical accident that the tense (...) of sentences in English if often indicated by means of the grammatical device of inflecting verbs, tensed verbs no longer seem to be the sort of item that needs to be purged from ordinary language in constructing its tenseless analogue. Indeed, although the distinction between tensed and tenseless verbs may still be of philosophic interest, this distinction hardly seems to deserve the pivotal role assigned to it in the literature.
