This book is a collection of critical engagements with Andrew Sayer, one of the foremost postdisciplinary thinkers of our times, with responses from Sayer himself.Sayer’s ground-breaking contributions to the fields of geography, political economy and social theory have reshaped the terms of engagement with issues and debates running from the methodology of social science through to the environment, and industrial development to the ethical dimensions of everyday life. Transatlantic scholars across a wide range of fields explore his work across four main areas: critical realism; moral economy; political economy; and relations between social theory, normativity and class.This is the first full-length critical assessment of Sayer’s work. It will be of interest to readers in sociology, economics, political economy, social and political philosophy, ethics, social policy, geography and urban studies, from upper-undergraduate levels upwards.
