From Occupy, to the Indignados and the Arab Spring, the uprisings that marked the last decade ignited a re-emergence of participatory democracy as a political ideal within organizations. This pioneering book introduces cybernetic thinking to politics and organizational studies to explore the continuing development of this radical idea. With a focus on communication and how alternative social media platforms present new challenges and opportunities for radical organising, it sheds new light on the concepts of self-organization, consensus decision making, individual autonomy and collective identity. Revolutionising the way in which anarchist activists and theorists think about organizations, this unprecedented investigation makes a major contribution to the larger discussion of direct democracy.
