Modals and Conditionals Endorsements for Angelika Kratzer’s Modals and Conditionals ‘Angelika Kratzer’s classic work on modality and conditionals is one of the major achievements of contemporary formal semantics. This collection of six of her path-breaking papers on the topic is invaluable. But what is most gratifying is that Kratzer substantially revised the papers, updating them and providing a wealth of retrospective comments. An indispensible resource for anyone inter- ested in semantics or the philosophy of language.’ Franc¸ois Recanati, Institut Jean Nicod ‘This book collects and revises two decades of the work that has shaped the modern view of the language of modals and conditionals: an invariant, univocal vocabulary that is variously understood with shifts in the conversational back- ground, a syntax that identifies if-clauses as the relative clauses restricting modal operators, and a semantics that discerns in the conversational background what is given and what would be best, given what is given. Just for the argument on which this foundation rests, the book deserves frequent and close study. The chapters tell another compelling story in which rivals for the meaning of conditionals are reconciled in a wedding of situation and thought—facts, so- called. One rival pleads that an if-clause is premise to reasoning of which the conditional is report. The other, in a familiar metaphysical turn, has suppressed mention of reasoning in favour of an assertion about ordering relations among possible worlds. Although it has been said (Lewis 1981) that formally there is nothing to choose between them, Angelika Kratzer demonstrates that only a semantics that includes premises gains a purchase on how and why the words chosen to express a conditional affect judgments about its truth. So, in repre- senting the foundations for the modern view, the author also offers a radical program to reform it. This book is a treasure of the puzzles, illustrations and parables that have informed the subject. It defines the standard against which all theorizing on modals and conditionals is to be measured.’ Barry Schein, University of Southern California ‘Modals and conditionals lie at the center of philosophical inquiry. In work beginning in the 1970s, Kratzer proposes a vantage point from which it can be seen that modals and conditionals share a common logical structure, that of quantification generally. This work collects and dramatically expands upon Angelika Kratzer’s now classic papers. There is scarcely an area of philosophy that remains or will remain untouched by their influence.’ Jason Stanley, Rutgers University OXFORD STUDIES IN THEORETICAL LINGUISTICS general editors David Adger, Queen Mary University of London; Hagit Borer, University of Southern California advisory editors Stephen Anderson, Yale University; Daniel Bu¨ring, University of California, Los Angeles; Nomi Erteschik-Shir, Ben-Gurion University; Donka Farkas, University of California, Santa Cruz; Angelika Kratzer, University of Massachusetts, Amherst; Andrew Nevins, University College London; Christopher Potts, Stanford University, Amherst; Barry Schein, University of Southern California; Peter Svenonius, University of Tromsø; Moira Yip, University College London Recent titles 20 Adjectives and Adverbs Syntax, Semantics, and Discourse edited by Louise McNally and Christopher Kennedy 21 InterPhases Phase-Theoretic Investigations of Linguistic Interfaces edited by Kleanthes Grohmann 22 Negation in Gapping by Sophie Repp 23 A Derivational Syntax for Information Structure by Luis Lo´pez 24 Quantification, Definiteness, and Nominalization edited by Anastasia Giannakidou and Monika Rathert 25 The Syntax of Sentential Stress by Arsalan Kahnemuyipour 26 Tense, Aspect, and Indexicality by James Higginbotham 27 Lexical Semantics, Syntax, and Event Structure edited by Malka Rappaport Hovav, Edit Doron, and Ivy Sichel 28 About the Speaker Towards a Syntax of Indexicality by Alessandra Giorgi 29 The Sound Patterns of Syntax edited by Nomi Erteschik-Shir and Lisa Rochman 30 The Complementizer Phase edited by E.
