The terms patriarchy, institutional racism, sustainable development and alienation may be familiar but this familiarity is often removed from the analytical contexts in which these ideas emerged. This book provides a series of rich reflections on the interaction between the radical ideas associated with these and other authors, and political action in Ireland. The classic texts that comprise the focal point for each chapter were selected by the contributors, many of whom straddle the boundaries of academia and activism. Each essay provides an account of the contributor’s personal encounters with the text, opens up the key mobilising ideas and considers how the text has the potential invigorate the political imagination of contemporary oppositional politics. This book will be of interest to students in the social sciences, especially sociology and Irish studies and will appeal to those interested or involved in political activism of any variety.
