Subjunctive Conditionals

Conditional sentences are among the most intriguing and puzzling features of language: analysis of their meaning and function has important implications for, and uses in, many areas of philosophy. Jonathan Bennett, one of the world's leading experts, distils many years' work and teaching into this Philosophical Guide to Conditionals, the fullest and most authoritative treatment of the subject. The literature on conditionals is difficult - needlessly so. Bennett's treatment is meticulously careful and luminously clear. He presents and evaluates in detail various approaches to the understanding of 'indicative' conditionals (like 'If Shakespeare didn't write Hamlet, some aristocrat did') and 'subjunctive' conditionals (like 'If rabbits had not been deliberately introduced into New Zealand, there would be none there today'); and he offers his own view, which will be recognized as a major original contribution to the subject. Journeying through this intellectual territory brings one into contact with the metaphysics of possible worlds, probability and belief-change, probability and logic, the pragmatics of conversation, determinism, ambiguity, vagueness, the law of excluded middle, facts versus events, and more. One might perhaps learn more philosophy from a thorough study of conditionals than from any other kind of work. Bennett's Guide is an ideal introduction for undergraduates with a philosophical grounding, and will also be a rich source of illumination and stimulation for graduate students and professional philosophers.

A proposal for a compositional semantics for subjunctive (or would) conditionals in English. In this book, Michela Ippolito proposes a compositional semantics for subjunctive (or would) conditionals in English that accounts for their felicity conditions and the constraints on the satisfaction of their presuppositions by capitalizing on the occurrence of past tense morphology in both antecedent and consequent clauses. Very little of the extensive literature on subjunctive conditionals tries to account for the meaning of these sentences compositionally or to relate this meaning to their linguistic form; this book fills that gap, connecting the different lines of research on conditionals. Ippolito's proposal will be of interest both to linguists and to philosophers concerned with conditionals and modality more generally. Ippolito reviews previous analyses of counterfactuals and subjunctive conditionals in the work of David Lewis, Robert Stalnaker, Angelika Kratzer, and others; considers the contrast between future simple past subjunctive conditionals and future past perfect subjunctive conditionals; presents a proposal for subjunctive conditionals that addresses puzzles left unsolved by previous proposals; reviews a number of presupposition triggers showing that they fit the pattern predicted by her proposal; and discusses an asymmetry between the past and the future among subjunctive conditionals, arguing that the best account of our linguistic intuitions must include an indeterministic view of the world.

The author, one of the world's leading authorities on the subject of conditional sentences, distils many years' work and teaching into 'A Philosophical Guide to Conditionals', an authoritative treatment of the subject.

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.

I am indebted to many people for the help they gave me in the writing of this book. lowe a large debt to David Lewis and Robert Stalnaker, on both general and specific grounds. As becomes apparent from reading the notes, the book would not have been possible without their pioneering work on subjunctive conditionals. In addition, both were kind enough to provide specific comments on earlier versions of different parts of the book, and Stalnaker read and commented on the entire manuscript. Closer to home, I am indebted to my colleagues Rolf Eberle and Henry Kyburg, Jf. , my erstwhile colleague Keith Lehrer, and numerous graduate students for their helpful comments on various parts of the manuscript. Some of the material contained herein appeared first in the form of journal articles, and I wish to thank the journals in question for allowing the material to be reprinted here. Chapter One contains material taken from 'The "Possible Worlds" Analysis of Counter-factuals', published in Phil. Studies 29 (1976), 469 (Reidel); Chapter Two contains material much revised from 'Four Kinds of Conditionals', Am. Phil. Quarterly 12 (1975), and Chapter Three contains much revised material from 'Subjunctive Generaliza tions', Synthese 28 (1974), 199 (Reidel). CHAPTER I INTRODUCTION 1. SUBJUNCTIVE REASONING There exists quite a variety of statements which are in some sense 'subjunctive'.

Timothy Williamson is one of the most influential living philosophers working in the areas of logic and metaphysics. His work in these areas has been particularly influential in shaping debates about metaphysical modality, which is the topic of his recent provocative and closely-argued book Modal Logic as Metaphysics (2013). This book comprises ten essays by metaphysicians and logicians responding to Williamson’s work on metaphysical modality, as well as replies by Williamson to each essay. In addition, it contains an original essay by Williamson, ‘Modal science,’ concerning the role of modal claims in natural science. This book was originally published as a special issue of the Canadian Journal of Philosophy.

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.

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.

An illustrious line-up of seventeen philosophers from the USA, the UK, and Australia present new essays on themes from the work of Frank Jackson, which bridges mind, language, logic, metaphysics, and ethics. Central to Jackson's work is an approach to metaphysical issues built on the twin foundations of supervenience and conceptual analysis. In the first part of the book six essays examine this approach and its application to philosophy of mind and philosophy of colour. The second part focuses on Jackson's highly influential work on phenomenal consciousness. The third part is devoted to Jackson's work in ethics, both normative ethics and metaethics. The last three papers discuss Jackson's ground-breaking work on conditionals. The final section of the book comprises a substantial essay by Jackson in reply to his critics: this offers some of the clearest expressions of the ideas which Jackson has brought to the fore in philosophy.
