"Barbara H. Partee is the founding mother of linguistic semantics as it is practiced today, and this collection of many of her classic papers shows why she has been so influential. The combination of theoretical insight with her legendary ability to find just the right example to make a point is evident throughout. And, as a bonus, the collection begins with a wonderful memoir of the turbulent time when semantics was getting its start." Robert Stalnaker, MIT "Two different audiences will be delighted with this book: those who read the classic papers gathered here when they first appeared and those who did not but are heirs to the rich semantics tradition in formal linguistics that Barbara H. Partee established with those papers and with her irresistible enthusiasm for systematic investigation of linguistic meaning. Partee's keen semantic insights, her flair for telling examples, her intellectual generosity, her clear-headedness, and her pedagogical talents are evident throughout, not just in the vintage pieces but also in the introductory essay she's written and in the couple of articles published more recently. This volume belongs on every semanticist's shelf." Sally McConnell-Ginet, Cornell University
