This book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses.

Conditionals has at its centre an extended essay on this problematic and much-debated subject in the philosophy of language and logic, which the widely respected Oxford philosopher Michael Woods had been preparing for publication at the time of his death in 1993. Woods discusses the distinction between different kinds of conditionals, and then goes on to cover a range of topics, including assertibility, conditional probability, possible-worlds theories, and conditional commands and questions. He ends up sketching a new theory of counterfactual conditionals. This essay is edited for publication by Wood's friend and colleague David Wiggins, and accompanied by a commentary specially written by a leading expert on the topic, Dorothy Edgington. The masterful and original treatment of conditionals presented in this book will demand the attention of all philosophers working in this area.

Robert C. Stalnaker presents a set of essays on the structure of inquiry. In the first part he focuses on the concepts of knowledge, belief, and partial belief, and on the rules and procedures we use - or ought to use - to determine what to believe, and what to claim that we know. In thesecond part he examines conditional statements and conditional beliefs, their role in epistemology, and their relations to causal and explanatory concepts, such as dispositions, objective chance, relations of dependence, and independence. A central concern of the book is the interaction of differentcognitive perspectives - the ways in which the attitudes of rational agents are or should be influenced by critical reflection on their present cognitive situation, on their own cognitive situations at other times, and on the cognitive situations of others with whom they interact.The general picture that is developed is naturalistic, following Hume in rejecting a substantive role for pure reason in the defense of inductive rules, and in giving causal concepts a central role in the description and explanation of our cognitive practices. However, Stalnaker rejects the side ofHume that aims to reduce concepts involving natural necessity to more basic descriptive concepts. Instead, he argues that the development of inductive rules and practices takes place in interaction with the development of concepts for giving a theoretical description of the world.

This collection of readings introduces the reader to the most interesting current work on conditionals. Particular attention is paid to possible worlds semantics for conditionals; the role of conditional probability in helping us to understand conditionals; implicature and the materialconditional; and subjective versus indicative conditionals. The volume brings together important papers by Frank Jackson, V. H. Dudman, Dorothy Edgington, Nelson Goodman, H. P. Grice, David Lewis, and Robert Stalnaker. Oxford Readings in Philosophy is a series designed to bring together important recent writings in major areas of philosophical inquiry, selected from a variety of sources, mostly periodicals, which may not be conveniently available to the university student or the general reader. The editor ofeach volume contributes an introductory essay on the items chosen and on the questions with which they deal. A selective bibliography is appended as a guide to further reading.

What does 'if' mean? Timothy Williamson presents a controversial new approach to understanding conditional thinking, which is central to human cognitive life. He argues that in using 'if' we rely on psychological heuristics, fast and frugal methods which can lead us to trust faulty data and prematurely reject simple theories.

This book constitutes the thoroughly refereed postproceedings of the International Workshop on Conditionals, Information, and Inference, WCII 2002, held in Hagen, Germany in May 2002. The 9 revised full papers presented together with 3 invited papers by leading researchers in the area were carefully selected during iterated rounds of reviewing and improvement. The papers address all current issues of research on conditionals, ranging from foundational, theoretical, and methodological aspects to applications in various contexts of knowledge representation.

Addresses central questions concerning conditionals by combining the methods of formal epistemology with those of cognitive psychology.
