The nature of the information content of declarative sentences is a central topic in the philosophy of language. The natural view that a sentence like "John loves Mary" contains information in which two individuals occur as constituents is termed the naive theory, and is one that has been abandoned by most contemporary scholars. This theory was refuted originally by philosopher Gottlob Frege. His argument that the naive theory did not work is termed Frege's puzzle, and his rival account of information content is termed the orthodox theory. In this detailed study, Nathan Salmon defends a version of the naive theory and presents a proposal for its extension that provides a better picture of information content than the orthodox theory gives. He argues that a great deal of what has generally been taken for granted in the philosophy of language over the past few decades is either mistaken or unsupported, and consequently, much current research is focused on the wrong set of questions. Salmon dissolves Frege's puzzle as it is usually formulated and demonstrates how it can be reconstructed and strengthened to yield a more powerful objection to the naive theory. He then defends the naive theory against the new Frege puzzle by presenting an idea that yields both a surprisingly rich and powerful extension of the naive theory and a better picture of information content than that of the original orthodox theory. Nathan Salmon is Professor of Philosophy, University of California at Santa Barbara. A Bradford Book.

Richard Pettigrew offers an extended investigation into a particular way of justifying the rational principles that govern our credences (or degrees of belief). The main principles that he justifies are the central tenets of Bayesian epistemology, though many other related principles are discussed along the way. These are: Probabilism, the claims that credences should obey the laws of probability; the Principal Principle, which says how credences in hypotheses about the objective chances should relate to credences in other propositions; the Principle of Indifference, which says that, in the absence of evidence, we should distribute our credences equally over all possibilities we entertain; and Conditionalization, the Bayesian account of how we should plan to respond when we receive new evidence. Ultimately, then, this book is a study in the foundations of Bayesianism. To justify these principles, Pettigrew looks to decision theory. He treats an agent's credences as if they were a choice she makes between different options, gives an account of the purely epistemic utility enjoyed by different sets of credences, and then appeals to the principles of decision theory to show that, when epistemic utility is measured in this way, the credences that violate the principles listed above are ruled out as irrational. The account of epistemic utility set out here is the veritist's: the sole fundamental source of epistemic utility for credences is their accuracy. Thus, Pettigrew conducts an investigation in the version of epistemic utility theory known as accuracy-first epistemology. The book can also be read as an extended reply on behalf of the veritist to the evidentialist's objection that veritism cannot account for certain evidential principles of credal rationality, such as the Principal Principle, the Principle of Indifference, and Conditionalization.

Time travel is metaphysically possible. Nikk Effingham contends that arguments for the impossibility of time travel are not sound. Focusing mainly on the Grandfather Paradox, Effingham explores the ramifications of taking this view, discusses issues in probability and decision theory, and considers the potential dangers of travelling in time.

Challenges the idea that representation of how the world is should play a fundamental explanatory role in any explanation of language. Examines deflationary accounts of truth, the role of language in expressing mental states, and the normative and the natural as they relate to issues of representation.

When the logical positivists espoused emotivism as a theory of moral discourse, they assumed that their general theories of meaning could be straightforwardly applied to the subject of metaethics. The philosophical research program of expressivism, emotivism's contemporary heir, has called this assumption into question. In this volume Mark Schroeder argues that the only plausible ways of developing expressivism or similar views require us to re-think what we may have thought that we knew about propositions, truth, and the nature of attitudes like belief and desire. Informed by detailed scrutiny of the structural problems about understanding complex thoughts, he develops a range of alternative expressivist frameworks in detail as illustrations of general lessons, and applies them not just to metaethics, but to epistemic expressions and even to truth itself. Expressing Our Attitudes pulls together over a decade of work by one of the leading figures in contemporary metaethics. Two new and seven previously published papers weave treatments of propositions, truth, and the attitudes together with detailed development of competing alternative expressivist frameworks and discussion of their relative advantages. A substantial new introduction both offers new arguments of its own, and provides a map to reading these essays as a unified argument. Along with its sister volume, Explaining the Reasons We Share, this volume advances the theme that metaethical inquiry is continuous with other areas of philosophy.

This volume explores the use of higher-order logics in metaphysics. Seventeen original essays trace the development of higher-order metaphysics, discuss different ways in which higher-order languages and logics may be used, and consider their application to various central topics of metaphysics.

This anthology is the first book to give a balanced overview of the competing theories of degrees of belief. It also explicitly relates these debates to more traditional concerns of the philosophy of language and mind and epistemic logic.

The concepts of meaning and mental content resist naturalistic analysis. This is because they are normative: they depend on ideas of how things ought to be. Allan Gibbard offers an expressivist explanation of these 'oughts': he borrows devices from metaethics to illuminate deep problems at the heart of the philosophy of language and thought.
