This book explores graded expressions of modality, a rich and underexplored source of insight into modal semantics. Studies on modal language to date have largely focussed on a small and non-representative subset of expressions, namely modal auxiliaries such as must, might, and ought. Here, Daniel Lassiter argues that we should expand the conversation to include gradable modals such as more likely than, quite possible, and very good. He provides an introduction to qualitative and degree semantics for graded meaning, using the Representational Theory of Measurement to expose the complementarity between these apparently opposed perspectives on gradation. The volume explores and expands the typology of scales among English adjectives and uses the result to shed light on the meanings of a variety of epistemic and deontic modals. It also demonstrates that modality is deeply intertwined with probability and expected value, connecting modal semantics with the cognitive science of uncertainty and choice.

This contributed volume includes both theoretical research on philosophical logic and its applications in artificial intelligence, mostly employing the concepts and techniques of modal logic. It collects selected papers presented at the Second Asia Workshop on Philosophical Logic, held in Guangzhou, China in 2014, as well as a number of invited papers by specialists in related fields. The contributions represent pioneering philosophical logic research in Asia.

What do we mean when we say things like 'If only we knew what he was up to!' Clearly this is more than just a message, or a question to our addressee. We are expressing simultaneously that we don't know, and also that we wish to know. Several modes of encoding contribute to such modalities of expression: word order, subordinating subjunctions, sentences that are subordinated but nevertheless occur autonomously, and attitudinal discourse adverbs which, far beyond lexical adverbials of modality, allow the speaker and the listener to presuppose full agreement, partial agreement under presupposed conditions, or negotiation of common ground. This state of the art survey proposes a new model of modality, drawing on data from a variety of Germanic and Slavic languages to find out what is cross-linguistically universal about modality, and to argue that it is a constitutive part of human cognition.

Current semantic fieldwork research has shown that the study of modality cannot be conducted via translation alone, yet much of what we know about modal expressions across the world’s language is still translation-based. This book aims to facilitate the study of modality across more diverse languages and a wider participant base by explaining and illustrating a nuanced set of methods, including storyboards, questionnaires, corpora research, experimental tasks, as well as a discussion of practical semantic fieldwork techniques. The methodological protocols tested and employed by the authors on underdescribed languages - spanning seven different language families - are intended to be applicable as cross-linguistic tools, while also indicating the successes and challenges of their contributions. Expanding the study of modality to a wider set of underdescribed languages will undoubtedly bring new insights into our theoretical understanding of modality and deepen our understanding of a cross-linguistic typology of modal expressions.

Locating the subjunctive at the interface of mood and modality, this book presents a systematic description of the use of the English subjunctive in main clauses, noun clauses, relative clauses, and adverbial clauses. It explores the factors which governed its competition with other verbal expressions in texts ranging from the 9th to the beginning of the 18th century. Employing close reading alongside analysis of corpus data and the use of descriptive statistics, it offers new insights into the research landscape of English subjunctive use and into the fields of historical English linguistics and corpus linguistics.

This book constitutes the refereed proceedings of the 30th International Conference on Logic-Based Program Synthesis and Transformation, LOPSTR 2020, which was held during September 7-9, 2020. The 15 papers presented in this volume were carefully reviewed and selected from a total of 31 submissions. The book also contains two invited talks in full paper length. The contributions were organized in topical sections named: rewriting; unification; types; verification; model checking and probabilistic programming; program analysis and testing; and logics.
