This book brings together a collection of essays by progressive global activists in response to Samir Amin’s call for a new global organization of progressive workers and peoples. Amin’s proposal is applauded, criticized and reformulated by these scholar-activists who are all proponents of ways forward toward a more egalitarian world society.Samir Amin, a leading scholar and co-founder of the world-system tradition, died on August 12, 2018. Just before his death, he published, along with close allies, a call for ‘workers and the people’ to establish a ‘fifth international’ to coordinate support for progressive movements. Amin, an Egyptian economist, was an intrepid intellectual and organizer of popular movements whose scholar activism provided inspiration to the global justice movement. The essays in this volume are by other prominent scholar activists who praise, critique and reconfigure Amin’s proposal in order to help humanity confront the contemporary crisis of global capitalism and move toward a more egalitarian global society.The chapters in this book were originally published in the journal, Globalizations.
