[1]. Recently renewed interest in non transformational approaches to syntax [2] suggests that it might be well to take another look at categorial grammars, since they seem to have been neglected largely because they had been shown to be equivalent to context free phrase structure grammars in weak generative capacity and it was believed that such grammars were incapable of describing natural languages in a natural way. It is my purpose here to sketch a theory of grammar which represents a (...) generalization of categorial grammars of the sort invented by Ajdukiewicz (1935) and further elaborated especially by Bar Hillel (1953) and Lambek (1961).

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.

The controversies surrounding Daniel Everett's characterization of the Amazonian language Pirahã and the Evans and Levinson paper about "the myth of language universals" (2009) are just two recent manifestations of a debate about linguistic theory and methodology that is anything but new.

This extended collection of papers is the result of putting recent ideas on quantification to work on a wide variety of languages.

Theme of two lectures: how does meaning work in grammar and lexicon? General question: Are morphemes the minimal meaningful units of language? Are the meanings of the parts of words of the same kind as those of syntax? The answer to this question has an obvious bearing on the question of the derivation of complex words "in the syntax." Is the split between syntax and morphology the proper division for asking the previous question? Answer: No. The crucial distinction is that (...) between grammar and lexicon. Framework: model theoretic semantics and constructive categorial syntax.. (shrink)

The term "morphosemantics" in the title of this talk is intended to raise a fundamental question about linguistic expressions and their meanings. When we talk about the meanings of morphemes and their combination into words should we expect to find the same kinds of meanings and combinations of meanings that we associate with the processes of putting together words into phrases? The answers to this question vary widely or even wildly across different linguists and their schools or theories. For example, (...) some linguists would say: "Decidedly not, since morphemes don't have any meanings at all. Meaning only begins with words and their combinations." Others would say: "Yes, of course! Complex words and their meanings are built up in syntax, so we predict that their complex meanings are made up uniformly across words and syntactic phrases.". (shrink)

0. Introductory remarks. I assume that every serious theory of language must give some explicit account of the relationship between expressions in the language described and expressions in some interpreted language which spells out the semantics of the language.1 Let's call this relationship the translation relation. Theories differ as to how this relation is specified. In the Aspects theory of syntax, taken together with a Katz-Postal view of "semantic rules" (Chomsky 1965; Katz and Postal, 1964), it was assumed that (...) the relation was defined on deep structures. Serious problems led to modifications of this view in several directions ('generative' and 'interpretive' semantics). Chomsky's latest papers (1976, 1975a: Ch. 3) assume that a modified 'intermediate structure' (surface structure with traces) is transformed by rules of interpretation to a level of representation called 'logical form' (which is input to further rules). Common to all of these approaches is the assumption that the translation rules are defined initially on syntactic structures of one sort or another (sometimes from several 'levels' at once). Let us call this assumption the configurational hypothesis: the translation rules all have the form: [183]. (shrink)

About: the tensions between the inner and outer view of R-languages ("real languages"), the language-centered and theory-centered study of languages, the (often foreign) linguist and the (sometimes linguist) native speaker, description and theory, a language as a set of choices and extensions of universal grammar and as a concrete realization in a particular culture and history. The materials for this paper are drawn mostly from First Nations languages, especially those of the Pacific Northwest.

We conceive of a player in dynamic games as a set of agents, which are assigned the distinct tasks of reasoning and node-specific choices. The notion of agent connectedness measuring the sequential stability of a player over time is then modeled in an extended type-based epistemic framework. Moreover, we provide an epistemic foundation for backward induction in terms of agent connectedness. Besides, it is argued that the epistemic independence assumption underlying backward induction is stronger than usually presumed.

A language is specified by a Lexicon and a Grammar. A constructive grammar goes like this: The Lexicon provides a set of items. The items are associated with Categories and Denotations. The Grammar gives a recursive specification of the language by defining sets of derived expressions starting with the Lexicon as the base and allowing the combination of lexical items into expressions with their Categories and Denotations, by a rule-to-rule procedure, and so on ad libitum.

All over the world, local languages are facing possible or probable extinction. The situation is nowhere more acute than for First Nations* in the regions now called the United States of America and Canada. In the face of this situation many people have become interested in studying endangered languages. Interest in threatened languages comes from many different sides: commercial, academic, scientific, religious, and more. The most immediately affected are of course the very speakers of the languages and the communities where (...) they live or have lived. (shrink)

Many (all?) languages regiment differences between main and subordinate clauses and between straightforward assertions and other kinds of expressions. There are two main ways of expressing grammatical differences in natural languages: structural and inflectional. Other resources: lexical, intonational, etc.

I want to do two things here today. First, I want to describe and comment on some materials in and on Western Abenaki. Second, I want to make some additions to the various lists of Western Abenaki verb forms that have been available from published sources. This will be strictly a report on work in progress. Let me make acknowledgments right off to two colleagues: Roger Higgins, who has been working on Wampanoag (Massachusett) for some years, and Roy Wright, with (...) whom I have been collaborating on some of the WA materials, as I will report in a minute. And I want to give special thanks to Cécile Wawanolett, who first introduced me to her language. I put my email address on the handout. I would appreciate any comments that you might care to send to me on what I present here today. (shrink)

We analyze the sequential structure of dynamic games with perfect information. A three-stage account is proposed, that species setup, reasoning and play stages. Accordingly, we define a player as a set of agents corresponding to these three stages. The notion of agent connectedness is introduced into a type-based epistemic model. Agent connectedness measures the extent to which agents' choices are sequentially stable. Thus describing dynamic games allows to more fully understand strategic interaction over time. In particular, we provide suffcient conditions (...) for backward <span class='Hi'>induction</span> in terms of agent connectedness. Also, our framework makes explicit that the epistemic independence assumption involved in backward <span class='Hi'>induction</span> reasoning is stronger than usually presumed, and makes accessible multiple-self interpretations for dynamic games.

...the true difference between languages is not in what may or may not be expressed but in what must or must not be conveyed by the speakers.

Smalgyaxian (Tsimshianic): located along Nass River, the lower reaches of the Skeena and on coastal and island communities around and below mouth of Skeena and in Metlakatla, Alaska. Four languages: Coast Tsimshian (CT), Southern Tsimshian (ST); Nisg̱aʼa (Ni), Gitksan (Gi). The punctuation indicates subgrouping: Nisg̱aʼa and Gitksan are very close, the distinction being more political than linguistic. Southern Tsimshian (Sgu̎u̎x) is spoken by only a few people (in one..

Summary: demonstrative and determiner systems in the Pacific Northwest show areal similarities. The categories include two or three way deictic distinctions, visibility, modality (existent - non existent), and temporal contrasts. There are formal characteristics that are shared as well. The presentation will give a preliminary survey of the features across some languages of the area, with emphasis on Northern Wakashan. Then we will look at two especially interesting categories: `just gone' in Upper North Wakashan, which combines spatial and temporal (or: (...) spatiotemporal) concepts, `visible-invisible', which seems to be basically evidential and modal in some languages.

In the tradition of Stalnaker (1978,2002, context can be regarded as a set of assumptions that are mutually shared by a group of epistemic agents.An obvious generalization of this view is to explicitly represent each agent’s assumptions in a given situation and update them accordingly when new information is accepted. I lay out a number of philosophical and linguistic requirements for using such a model in order to describe communication of ideally-rational agents. In particular,the following questions are addressed: -/- 1. (...) What is the logical status of assumptions as opposed to rational belief, how are these assumptions generated from an underlying belief base in a given interpretation situation,and how are assumptions revised/contracted? -/- 2.What kind of ideal reasoning processes underly the interpretation of ‘incomplete’ content that may for example be obtained by an agent from an utterance by deriving some literal meaning from the lexicon and a grammar? -/- Regarding the first set of questions, my proposal is to consider assumptions akin to rational belief, but not stronger than modal logic KD, since positive and negative introspection do not seem to hold for them.Given that, an obvious question is what the relation between beliefs and assumptions is. One possible answer is to generate an agent’s assumptions from an agent’s beliefs in a given interpretation situation by revising his beliefs with his beliefs about what the message sender believes in that situation. If such an account is based on AGM belief revision/contraction(Alchourrón 1985, Gärdenfors 1989)there is a number of well-known problems that need to be addressed, because revision of iterated belief modalities is required in this case. These problems have already been investigated in detail in recent works on DDL Leitgeb/Segerberg 2007)and DEL see e.g. Ditmarsch et. (2008) Another strategy would be to maintain and revise assumptions independently of the beliefs of an agent.I will briefly discuss the advantages and disadvantages of each of these views. In both views, assumptions constitute the subjective context in which an agent interprets an utterance and encounters the world. The result of an interpretation is in turn checked against the agent’s original beliefs, and if the checking operation succeeds the agent revises his beliefs by the result in the normal way described by the AGM paradigm. -/- The second of the above questions needs to be addressed on the basis of concrete examples. Considering utterance like David is ready’ or ‘John is tall’that from a contextualist viewpoint express semantically incomplete content in the sense of Bach(2005, 2007, how may an agent arrive at interpretations of these utterances that are more complete? A first step is to presume that missing semantic ingredients are represented by missing argument places, which is a problematic assumption as it introduces a dependence on the semantic representation language. Given that, a default interpretation can be obtained by existentially quantifying over the missing argument and interpretation can then be regarded as an inference process. In case of the two examples mentioned,the assumptions of the agent allow him to obtain more specific readings by instantiating a value for the existentially bound variable.<span class='Hi'></span> As I will show,<span class='Hi'></span> this inference can be relatively straightforward in some cases like <span class='Hi'></span>‘John is tall’<span class='Hi'></span>, whereas it requires complicated encyclopedic background knowledge and a number of default reasoning steps in other cases.<span class='Hi'></span> -/- Based on more examples of this kind,<span class='Hi'></span> I argue that first,<span class='Hi'></span> belief revision with iterated modalities in a multi-agent setting is needed to generate an agent’s assumptions as laid out above.<span class='Hi'></span> Second,<span class='Hi'></span> default reasoning is needed.<span class='Hi'></span> Third,<span class='Hi'></span> a qualitative or quantitative representation of uncertainty <span class='Hi'></span>(‘degrees of belief’<span class='Hi'></span>) is needed in order to obtain a useful model of the checking step,<span class='Hi'></span> since fortunately not everybody believes everything that other people say.<span class='Hi'></span> These requirements put the theory of interpretation based on assumptions in the frontline of ongoing research on the implementation of belief revision and update in dynamic logics.<span class='Hi'></span> Such a theory might also be useful for contextualist accounts of strong knowledge,<span class='Hi'></span> as it can be argued convincingly that when a knowledge ascription appears to be context-sensitive,<span class='Hi'></span> this is so because the embedded proposition is context-sensitive and not because knowledge itself is context-sensitive.<span class='Hi'></span> Hence,the context-sensitivity of embedded propositions in knowledge claims and how different agents in the same situation arrive at different assessments about them may be explained by an inferential theory of interpretation similar to the one outlined here but with another underlying concept of assumptions.<span class='Hi'></span> -/- Literature <span class='Hi'></span> Alchourrón,<span class='Hi'></span> C.<span class='Hi'></span> E.<span class='Hi'></span>; Gärdenfors,<span class='Hi'></span> P.<span class='Hi'></span> &<span class='Hi'></span> Makinson,<span class='Hi'></span> D.<span class='Hi'></span> (1985)<span class='Hi'></span>, <span class='Hi'></span>'On the logic of theory change:<span class='Hi'></span> partial meet contraction and revision functions'<span class='Hi'></span>, Journal of Symbolic Logic(50)<span class='Hi'></span>, 510-530.<span class='Hi'></span> -/- Bach,<span class='Hi'></span> K.<span class='Hi'></span> (2007)<span class='Hi'></span>, <span class='Hi'></span>'Minimalism for Dummies:<span class='Hi'></span> Reply to Cappelen and Lepore'<span class='Hi'></span>, Technical report,<span class='Hi'></span> University of San Fransisco,<span class='Hi'></span> Department of Philosophy.<span class='Hi'></span> -/- Bach,<span class='Hi'></span> K.<span class='Hi'></span> (2005)<span class='Hi'></span>, Context ex Machina,<span class='Hi'></span> in án Gendler Szabó,<span class='Hi'></span> ed.<span class='Hi'></span>,'Semantics versus Pragmatics'<span class='Hi'></span>, Oxford UP,<span class='Hi'></span> Oxford,<span class='Hi'></span> pp.<span class='Hi'></span> 16-44.<span class='Hi'></span> -/- Ditmarsch,<span class='Hi'></span> H.<span class='Hi'></span> v.<span class='Hi'></span>; Hoek,<span class='Hi'></span> W.<span class='Hi'></span> v.<span class='Hi'></span> d.<span class='Hi'></span> &<span class='Hi'></span> Kooi,<span class='Hi'></span> B.<span class='Hi'></span> (2008)<span class='Hi'></span>, Dynamic Epistemic Logic,<span class='Hi'></span> Kluwer.<span class='Hi'></span> -/- Gärdenfors,<span class='Hi'></span> P.<span class='Hi'></span> (1988)<span class='Hi'></span>, Knowledge in Flux,<span class='Hi'></span> MIT Press.<span class='Hi'></span> -/- Leitgeb,<span class='Hi'></span> H.<span class='Hi'></span> &<span class='Hi'></span> Segerberg,<span class='Hi'></span> K.<span class='Hi'></span> (2007)<span class='Hi'></span>, <span class='Hi'></span>'Dynamic doxastic logic:<span class='Hi'></span> why,<span class='Hi'></span> how,<span class='Hi'></span> and where to?<span class='Hi'></span>',<span class='Hi'></span> Synthese155(2)<span class='Hi'></span>, 167-190.<span class='Hi'></span> -/- Stalnaker,<span class='Hi'></span> R.<span class='Hi'></span> (1978)<span class='Hi'></span>, Assertion,<span class='Hi'></span> in <span class='Hi'></span>.
