In this stunningly original work, John P. Clark skilfully argues that a free and just social order requires a radical transformation of the modes of domination exercised through social ideology, the social imaginary, the social ethos, and social institutional structures. Communitarian anarchism unites a universalist concern for social and ecological justice while recognising the integrity and individuality of the person. The Impossible Community is a renewed examination of the anarchist principles of mutual aid and voluntary cooperation and provides convincingly lucid examples in various contexts, from the rebuilding of New Orleans after Katrina to social movements in South Asia.
