Claims about what is metaphysically necessary or possible have long played a central role in metaphysics and other areas of philosophy. Such claims are traditionally thought of as aiming to describe a special kind of modal fact or property, or perhaps facts about other possible worlds. But that assumption leads to difficult ontological, epistemological, and methodological puzzles. Should we accept that there are modal facts or properties, or other possible worlds? If so, what could these things be? How could we come to know what the modal facts or properties are? How can we resolve philosophical debates about what is metaphysically necessary or possible? Norms and Necessity develops a new approach to understanding our claims about metaphysical possibility and necessity: Modal Normativism. The Normativist rejects the assumption that modal claims aim to describe modal features or possible worlds, arguing instead that they serve as useful ways of conveying, reasoning with, and renegotiating semantic rules and their consequences. By dropping the descriptivist assumption, the Normativist is able to unravel the notorious ontological problems of modality, and provide a clear and plausible story about how we can come to know what is metaphysically necessary or possible. Most importantly, this approach helps demystify philosophical methodology. It reveals that resolving metaphysical modal questions does not require a special form of philosophical insight or intuition. Instead, it requires nothing more mysterious than empirical knowledge, conceptual mastery, and an ability to explicitly convey and renegotiate semantic rules.

This book is about the idea that some true statements would have been true no matter how the world had turned out, while others could have been false. It develops and defends a version of the idea that we tell the difference between these two types of truths in part by reflecting on the meanings of words. It has often been thought that modal issues—issues about possibility and necessity—are related to issues about meaning. In this book, the author defends the view that the analysis of meaning is not just a preliminary to answering modal questions in philosophy; it is not merely that before we can find out whether something is possible, we need to get clear on what we are talking about. Rather, clarity about meaning often brings with it answers to modal questions. In service of this view, the author analyzes the notion of necessity and develops ideas about linguistic meaning, applying them to several puzzles and problems in philosophy of language. Meaning and Metaphysical Necessity will be of interest to scholars and advanced students working in metaphysics, philosophy of language, and philosophical logic.

Recent decades have witnessed an impressive process of normative development in international law. Numerous new treaties have been concluded, at global and regional levels, establishing far-reaching international legal and regulatory regimes in important areas such as human rights, international trade, environmental protection, criminal law, intellectual property, and more. New political and judicial institutions have been established to develop, apply and adjudicate these rules. This trend has been accompanied by the growing consolidation of treaty norms into international custom, and increased references to international law in domestic settings. As a result of these developments, international relations have now reached an unprecedented level of normative density and intensity, but they have also given rise to the phenomenon of 'fragmentation'. The debate over the fragmentation of international law has largely focused on conflicts: conflicts of norms and conflicts of authority. However, the same developments that have given rise to greater conflict and contradiction in international law, have also produced a growing amount of normative equivalence between rules in different fields of international law. New treaty rules often echo existing international customary norms. Regional arrangements reinforce undertakings that already exist at the global level; and common concerns and solutions appear in many international legal fields. This book focuses on such instances of normative parallelism, developing the concept of 'multisourced equivalent norms' in international law, with contributions by leading international law experts exploring the legal and political implications of the concept in a variety of contexts that span the full spectrum of international legal norms and institutions. By concentrating on situations governed by a multitude of similar norms, the book emphasizes the importance of legal contexts and institutional settings to international law-interpretation and application.

We spend a great deal of time learning our vocations and avocations as we work at jobs, participate in home life, and take part in civic activities and politics. In doing so, we engage in practices that consist of complex bodies of norms. These practices themselves are bodies of knowledge-often acquired from others-about what we take to be good ways or right ways to do certain things. As we learn how to solve problems and act on this knowledge, the practice itself changes. In Norms and Practices, James D. Wallace shows that norms of all kinds, including ethical norms, are intensely social constructs learned through constant interaction with others. Wallace suggests that ethical norms have long been misunderstood as practice-independent prescriptions for behavior; he regards them instead as items of practical knowledge that are constituents of practices. We are given the luxury of learning from others' mistakes and successes, often in a very informal way. Such lessons from collective or individual experience often carry more weight than do pronouncements from an external source. Wallace shows that practices and norms, including ethical norms within such spheres as biomedical research, family life, and politics, continually change as practitioners face novel problems.

Foundations of Mind collects the essays which established Tyler Burge as a leading philosopher of mind. This second volume of his papers offers nineteen pieces published between 1975 and 2003, including the influential series that develops anti-individualism. Burge contributes three essay-length postscripts, a substantial new paper on consciousness, and an introduction which surveys his work in this area. The foundations that Burge reflects on are conditions in the individual or the wider world that determine the natures of mental kinds. The conditions include causal, social, psychological conditions, and conditions of phenomenal consciousness. Some of these are basic conditions under which minds are possible. The book is essential reading for philosophers of mind, and should engage a wider public interested in basic philosophical issues.

This book constitutes revised selected papers from the thoroughly refereed proceedings of the International Workshop on Coordination, Organizations, Institutions, Norms, and Ethics for Governance of Multi-Agent Systems XIV, COINE 2021, held in London, UK, May 3, 2021. The 9 full papers included in this book were carefully reviewed and selected from 12 submissions. They were organized in topical sections as follows: Invited talk; conceptual frameworks architectures for collaboration and coordination; and modelling and understanding social behaviour using COINE technologies.
