"With this book Henry Yeung puts Geography back into the driver's seat of new theory development. Foregrounding mid-range theories and mechanism-based explanations, he offers a pragmatic approach that has the capacity to shape the wider social sciences for years to come. The timing of this intervention is pitch-perfect, as scholars search for ways to understand and intervene in an increasingly distrustful and polarized world." - Katharyne Mitchell, Distinguished Professor, University of California, Santa Cruz, USA"Critical human geography possesses a distinctive theory culture—pluralist, creative, distributed, restless, contested—prone to “turning,” wary of orthodoxies and fixed positions. In this original and provocative contribution, the leading economic geographer Henry Yeung steps out beyond his home turf to engage styles and practices of theorizing across this diverse field, carving out a new remit and rubric for middle-range theorizing." - Jamie Peck, Canadian Research Chair and Distinguished University Scholar, University of British Columbia, Canada
