This chapter illustrates the importance of broadening the understanding of social anarchism. Social anarchism has shifted its ground as it has embraced some elements of poststructuralist philosophy. This shift in territory from social to poststructuralist anarchism is most noticeable and particularly important at two levels of theory. The first, and the one that underscores the others, is the poststructuralist denunciation of foundationalist discourses or narratives. The second shift in theoretical territory is less pronounced but nonetheless real. The chapter suggests that, when situated alongside the practices of new social movements associated with the anticapitalist protests, the poststructuralist perspective affords insight into how new modes of anarchist practice are emerging. It also highlights how anarchist theory and practice is evolving into something distinct and is, at the same time, nurturing contemporary modes of resistance against traditional social, political and economic forms of oppression.
