'Michael Israel's magisterial study of the scalar foundations of polarity confirms beyond the slightest shadow of a doubt that little things do mean a lot. With clarity, elegance and wit, Israel pries open the black box of polarity licensing (no mean feat!) to demonstrate the role of scalar models at the heart of emphasis, attenuation, and rhetorical effects. This book is essential - and delightful - reading for all linguists, philosophers, and cognitive scientists with an interest in meaning and understanding.' Laurence Horn, Yale University
