This paper investigates the way that linguistic expressions influence vagueness, focusing on the interpretation of the positive (unmarked) form of gradable adjectives. I begin by developing a semantic analysis of the positive form of ‘relative’ gradable adjectives, expanding on previous proposals by further motivating a semantic basis for vagueness and by precisely identifying and characterizing the division of labor between the compositional and contextual aspects of its interpretation. I then introduce a challenge to the analysis from the class of ‘absolute’ (...) gradable adjectives: adjectives that are demonstrably gradable, but which have positive forms that relate objects to maximal or minimal degrees, and do not give rise to vagueness. I argue that the truth conditional difference between relative and absolute adjectives in the positive form stems from the interaction of lexical semantic properties of gradable adjectives—the structure of the scales they use—and a general constraint on interpretive economy that requires truth conditions to be computed on the basis of conventional meaning to the extent possible, allowing for context dependent truth conditions only as a last resort.

ABSTRACT It has been frequently observed in the literature that assertions of plain sentences containing predicates like fun and frightening give rise to an acquaintance inference: they imply that the speaker has first-hand knowledge of the item under consideration. The goal of this paper is to develop and defend a broadly expressivist explanation of this phenomenon: acquaintance inferences arise because plain sentences containing subjective predicates are designed to express distinguished kinds of attitudes that differ from beliefs in that they can (...) only be acquired by undergoing certain experiences. Its guiding hypothesis is that natural language predicate expressions lexically specify what it takes for their use to be properly ‘grounded’ in a speaker's state of mind: what state of mind a speaker must be in for a predication to be in accordance with the norms governing assertion. The resulting framework accounts for a range of data surrounding the acquaintance inference as well as for striking parallels between the evidential requirements on subjective predicate uses and the kind of considerations that fuel motivational internalism about the language of morals. A discussion of how the story can be implemented compositionally and of how it compares with other proposals currently on the market is provided. (shrink)

Color adjectives have played a central role in work on language typology and variation, but there has been relatively little investigation of their meanings by researchers in formal semantics. This is surprising given the fact that color terms have been at the center of debates in the philosophy of language over foundational questions, in particular whether the idea of a compositional, truth-conditional theory of natural language semantics is even coherent. The challenge presented by color terms is articulated in detail in (...) the work of Charles Travis. Travis argues that structurally isomorphic sentences containing color adjectives can shift truth value from context to context depending on how they are used and in the absence of effects of vagueness or ambiguity/polysemy, and concludes that a deterministic mapping from structures to truth conditions is impossible. The goal of this paper is to provide a linguistic perspective on this issue, which we believe defuses Travis’ challenge. We provide empirical arguments that color adjectives are in fact ambiguous between gradable and nongradable interpretations, and that this simple ambiguity, together with independently motivated options concerning scalar dimension within the gradable reading accounts for the Travis facts in a simpler, more constrained, and thus ultimately more successful fashion than recent contextualist analyses such as those in Szabó (Perspectives on semantics, pragmatics and discourse: A festschrift for Ferenc Kiefer, 2001) or Rothschild and Segal (Mind Lang, 2009).

Subjective predicates have two interpretive and distributional characteristics that have resisted a comprehensive analysis. First, the use of a subjective predicate to describe an object is in general felicitous only when the speaker has a particular kind of familiarity with relevant features of the object; characterizing an object as _tasty,_ for example, implies that the speaker has experience of its taste. Second, subjective predicates differ from objective predicates in their distribution under certain types of propositional attitude verbs. The goal of (...) this paper is to argue that these features can be explained in a uniform way and within a broadly truth-conditional approach to semantic content, given a view of subjective language as an essentially pragmatic, context-sensitive phenomenon. Specifically, we propose that what renders an issue subjective in discourse is speakers’ awareness of _counterstance contingency_: contingency relative to information states that represent alternative pragmatic stances.

This paper examines the use of scalar adjectives in two contexts that have played a role in discussions of the subjective/objective distinction: ?faultless disagreement? discourses and the nonfinite complement position of the subjective attitude verb find. I argue that the pattern of distribution and interpretation of scalar adjectives in these contexts provides evidence for two sources for subjectivity, which are distinguished from each other in that one affects the grammatical properties of a predicate and one does not. The first kind, (...) which licenses appearance in the complement position of find, is based in the lexical semantics of predicates that encode qualitative assessments. The second kind, which gives rise to faultless disagreement effects, arises from uncertainty about the dimensions of evaluation that are involved in fixing the extension of a predicate in a context of utterance.

This paper uses the distribution and interpretation of antonymous adjectives in comparative constructions as an empirical basis to argue that abstract representations of measurement, or ‘degrees’, must be modeled as intervals on a scale, rather than as points, as commonly assumed. I begin by demonstrating that the facts in this domain must be accounted for in terms of the interaction of the semantics of adjectival polarity and the semantics of the comparative, rather than principles governing the (overt) expression of particular (...) types of adjectives in comparatives. I then show that a principled account of the full range of data under consideration can be constructed within a model in which degrees are formalized as intervals on a scale and adjectival polarity is characterized in terms of two structurally distinct and complementary sorts of `positive' and `negative' degrees.

This article investigates the semantics of sentences that express numerical averages, focusing initially on cases such as 'The average American has 2.3 children'. Such sentences have been used both by linguists and philosophers to argue for a disjuncture between semantics and ontology. For example, Noam Chomsky and Norbert Hornstein have used them to provide evidence against the hypothesis that natural language semantics includes a reference relation holding between words and objects in the world, whereas metaphysicians such as Joseph Melia and (...) Stephen Yablo have used them to provide evidence that apparent singular reference need not be taken as ontologically committing. We develop a fully general and independently justified compositional semantics in which such constructions are assigned truth conditions that are not ontologically problematic, and show that our analysis is superior to all extant rivals. Our analysis provides evidence that a good semantics yields a sensible ontology. It also reveals that natural language contains genuine singular terms that refer to numbers. (shrink)

Comparatives are among the most extensively investigated constructions in generative grammar, yet comparatives involving attributive adjectives have received a relatively small amount of attention. This paper investigates a complex array of facts in this domain that shows that attributive comparatives, unlike other comparatives, are well-formed only if some type of ellipsis operation applies within the comparative clause. Incorporating data from English, Polish, Czech, Greek, and Bulgarian, we argue that these facts support two important conclusions. First, violations of Ross’s Left Branch (...) Condition that involve attributive modifiers should not be accounted for in terms of constraints on LF representations (such as the Empty Category Principle), but rather in terms of the principle of Full Interpretation at the PF interface. Second, ellipsis must be analyzed as deletion of syntactic material from the phonological representation. In addition, we present new evidence from pseudogapping constructions that favors an articulated syntax of attributive modification in which certain types of attributive modifiers may occur outside DP.

It is well known that the interpretation of quantificational expressions in the comparative clause poses a serious challenge for semantic analyses of the English comparative. In this paper, we develop a new analysis of the comparative clause designed to meet this challenge, in which a silent occurrence of the negative degree quantifier no interacts with other quantificational expressions to derive the observed range of interpretations. Although our analysis incorporates ideas from previous analyses, we show that it is able to account (...) for a broader range of facts than other approaches, with a minimum of construction-specific stipulations. We demonstrate that the analysis can be embedded within a general syntactic and semantic architecture for the comparative, and although our analysis focuses on the English data, we give evidence of its potential for crosslinguistic application. We conclude with a discussion of the implications of our approach for the analysis of “split-scope” phenomena in nominal quantification. (shrink)

In this volume leading researchers present new work on the semantics and pragmatics of adjectives and adverbs, and their interfaces with syntax. Its concerns include the semantics of gradability; the relationship between adjectival scales and verbal aspect; the relationship between meaning and the positions of adjectives and adverbs in nominal and verbal projections; and the fine-grained semantics of different subclasses of adverbs and adverbs. Its goals are to provide a comprehensive vision of the linguistically significant structural and interpretive properties of (...) adjectives and adverbs, to highlight the similarities between these two categories, and to signal the importance of a careful and detailed integration of lexical and compositional semantics. The editors open the book with an overview of current research before introducing and contextualizing the remaining chapters. The work is aimed at scholars and advanced students of syntax, semantics, formal pragmatics, and discourse. It will also appeal to researchers in philosophy, psycholinguistics, and language acquisition interested in the syntax and semantics of adjectives and adverbs. (shrink)

Sexual abuse by clergymen, poisoned water, police brutality—these cases each involve two wrongs: the abuse itself and the attempt to avoid responsibility for it. Our focus is this second wrong—the cover up. Cover ups are accountability failures, and they share common strategies for thwarting accountability whatever the abuse and whatever the institution. We find that cover ups often succeed even when accountability mechanisms are in place. Hence, improved institutions will not be sufficient to prevent accountability failures. Accountability mechanisms are tools (...) that people must be willing to use in good faith. They fail when people are complicit. What explains complicity? We identify certain human proclivities and features of modern organizations that lead people to become complicit in the wrongdoing of others. If we focus exclusively on the design of institutions, we will fail to constrain the perpetrators of wrongdoing. Understanding complicity is key to understanding accountability failures. (shrink)

A test was administered to 102 engineering students to ascertain how engineering education influences their environmental knowledge and attitudes. Answers to definitional and factual questions in a forced-answer section demonstrated that students were improving their technical knowledge, but responses to more subtle questions were mixed. Answers to attitudinal questions exhibited a trend towards increased environmental awareness. For open-ended questions, posttest results showed an increase in knowledge of engineering work. Over 80% of the students considered themselves to have a caring attitude (...) toward the environment, with the “three R’s” and green transportation choices most commonly cited. Engagement in research, education, or advocacy doubled from pretest to posttest. Air pollution and solid waste disposal most frequently influenced students’ attitudes toward the environment. Outdoor experiences were the most frequently mentioned source of information; university courses rose from 4% to 15% on the posttest. Only 40% of the students could name an environmental role model.

Professional engineers are under increasing pressure to practice in an environmentally sensitive way. To prepare engineers for this new reality, changes in engineering education are needed. For example, engineering hydrology has traditionally been taught with an emphasis on the interpretation of numerical data bout rainfall and runoff in watersheds. However, to do environmentally sensitive hydrology work, it is necessary to also understand the life forms that share the watershed. In 1997, a project was undertaken in the Department of Civil Engineering (...) at the University of Toronto to enhance an introductory hydrology course by adding information about how hydrological phenomena affect fish. Through carefully structured assignments and exam questions, an assessment was made of the effectiveness of the enhancements in increasing students’ awareness of the life context of hydrology. The project has resulted in a commitment to increased environmental information in the hydrology curriculum, and the implementation of an assessment process for all students, to monitor changes in their environmental knowledge and attitudes. It has also raised questions about ultimate objectives in engineering education. (shrink)
