This comprehensive review and critical synthesis of research on modality focuses on formal theories within linguistics and related aspects of philosophical logic. It will be welcomed by students of linguistics at graduate level and above, as well as by researchers in philosophy, computational science, and related fields.

Part I of this book presents a theory of modal metaphysics in the possible-worlds tradition. `Worlds' themselves are understood as structured sets of properties; this `Ersatzist' view is defended against its most vigorous competitors, Meinongianism and David Lewis' theory of existent concrete worlds. Related issues of essentialism and linguistic reference are explored. Part II takes up the question of lexical meaning in the context of possible-world semantics. There are skeptical analyses of analyticity and the notion of a logical constant; and an `infinite polysemy' thesis is defended. The book will be of particular interest to metaphysicians, possible-world semanticists, philosophers of language, and linguists concerned with lexical semantics.

Modality - the question of what is possible and what is necessary - is a fundamental area of philosophy and philosophical research. The Routledge Handbook of Modality is an outstanding reference source to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising thirty-five chapters by a team of international contributors the Handbook is divided into seven clear parts: worlds and modality essentialism, ontological dependence, and modality modal anti-realism epistemology of modality modality in science modality in logic and mathematics modality in the history of philosophy. Within these sections the central issues, debates and problems are examined, including possible worlds, essentialism, counterfactuals, ontological dependence, modal fictionalism, deflationism, the integration challenge, conceivability, a priori knowledge, laws of nature, natural kinds, and logical necessity. The Routledge Handbook of Modality is essential reading for students and researchers in epistemology, metaphysics and philosophy of language. It will also be very useful for those in related fields in philosophy such as philosophy of mathematics, logic and philosophy of science.

The book presents new issues and areas of work in modality and evidentiality in English(es), and in relation to other European languages (French, Galician, Lithuanian, Spanish). Given the complexity of the relations among modal and evidential expressions, their constant diachronic evolution, and the variation found in different English-speaking areas, and in different genres and discourse domains, the volume addresses the following issues: the conceptual nature of modality, the relationship between the domains of modality and evidentiality, the evolution and current status of the modal auxiliaries and other modal expressions, the relationship with neighbouring grammatical categories (tense, aspect, mood), and the variation in different discourse domains and genres, in modelling stance and discourse identities.

People tend to enjoy listening to music or watching television, sleeping at night and celebrating birthdays. Plants tend to grow and thrive in sunlight and mild temperatures. We also know that tendencies are not perfectly regular and that there are patterns in the natural world, which are reliable to a degree, but not absolute. What should we make of a world where things tend to be one way but could be another? Is there a position between necessity and possibility? If there is, what are the implications for science, knowledge and ethics? This book explores these questions and is the first full-length treatment of the philosophy of tendencies. Anjum and Mumford argue that although the philosophical language of tendencies has been around since Aristotle, there has not been any serious commitment to the irreducible modality that they involve. They also argue that the acceptance of an irreducible and sui generis tendential modality ought to be the fundamental commitment of any genuine realism about dispositions or powers. It is the dispositional modality that makes dispositions authentically disposition-like. Armed with this theory the authors apply it to a variety of key philosophical topics such as chance, causation, epistemology and free will.

Palmer investigates the category of modality, drawing on a wealth of examples from a wide variety of languages.

What is a linguistic category and what kinds of categories do the labels subjunctive, imperative, future, aspect, and modality refer to? The current literature assumes a straightforward mapping between grammatical category and semantic function, and descriptions of well-studied languages cultivate a sense of predictability in patterns. However, as the editors and contributors of "Mood, Aspect, Modality Revisited" show, this predictability and stability vanish once lesser known patterns and languages are studied. While it is feasible to retain certain distinctions among tense, aspect, and mood (TAM) in analysis of specific issues in specific languages, ongoing formal and experimental research seems to indicate that these traditional grammatical distinctions may ultimately be illusionary. "Mood, Aspect, Modality Revisited" seeks more general or fundamental grammatical structures that can encompass the breadth of related concepts traditionally placed in the TAM categories."

This book covers the essentials of modality and offers both foundational ideas and cutting edge advances. The book consists of what are essentially tutorials on modality and modal notions, covering definitions of modality, morphosyntactic form, conceptual and logical semantics, historical development, and acquisition. There are also specific chapters on modality in Zapotec and American Sign Language, which show the range of forms that modal notions can take. To assist its tutorial function, the book closes with a comprehensive conceptual outline of all the chapters. Key features: new series textbook covers the essentials of modality

Here is a unique work of reference. Not only does it unite studies which explore the syntax and semantics of tense or modality, but it is the first book of its kind to embrace the interaction of tense and modality within a coherent generative model.

Modal logic is the study of modalities - expressions that qualify assertions about the truth of statements - like the ordinary language phrases necessarily, possibly, it is known/believed/ought to be, etc., and computationally or mathematically motivated expressions like provably, at the next state, or after the computation terminates. The study of modalities dates from antiquity, but has been most actively pursued in the last three decades, since the introduction of the methods of Kripke semantics, and now impacts on a wide range of disciplines, including the philosophy of language and linguistics ('possible words' semantics for natural language), constructive mathematics (intuitionistic logic), theoretical computer science (dynamic logic, temporal and other logics for concurrency), and category theory (sheaf semantics). This volume collects together a number of the author's papers on modal logic, beginning with his work on the duality between algebraic and set-theoretic modals, and including two new articles, one on infinitary rules of inference, and the other about recent results on the relationship between modal logic and first-order logic. Another paper on the 'Henkin method' in completeness proofs has been substantially extended to give new applications. Additional articles are concerned with quantum logic, provability logic, the temporal logic of relativistic spacetime, modalities in topos theory, and the logic of programs.
