In this highly prescient work - which has had a big impact on figures such as Pablo Oglesias of Podemos in Spain - Ernesto Laclau continues the philosophical and political exploration initiated in Hegemony and Socialist Strategy. Here he focuses on the construction of popular identities and how "the people" emerge as a collective actor. Skillfully combining theoretical analysis with a myriad of empirical references from numerous historical and geographical contexts he offers a critical reading of the existing literature on populism, demonstrating its dependency on the theorists of "mass psychology" such as Taine and Freud. He demonstrates the relation of populism to democracy and to the logic of representation, and differentiates his approach from the work of Zizek, Hardt and Negri, and Ranciere. This book is essential reading for all those interested in the question of political identities in a world marked by figures such as Trump, Farage, Le Pen as well as Sanders, Iglesias and Mélenchon.
