The European Social Forum (ESF) is an open space where civil society groups and movements opposed to neo-liberalism and a world dominated by capital or by any form of imperialism, but engaged in building a society centered on the human person, come together to pursue their thinking, to debate ideas democratically, to formulate proposals, to share their experiences freely and to network for effective action. This website is therefore an open space to facilitate the ESF process that was embodied in [Firenze,2002], [Paris,2003] and [London,2004] and will be in [Athens,2006].
