We are witnessing a visible rebirth of libertarian thinking that owes so much to the bankruptcy of social democracy and the models of real socialism and to the certification that capitalism is entering a phase of terminal corrosion that is nearing the moment of collapse. This volume examines many of the debates of those involved by contemporary libertarians, and in this regard we study, with non-dogmatic vocation, the theoretical proposal of anarchism, its criticism of liberal democracy and its defence of democracy and direct action, the response of the state and capitalism, the commitment to the gestation of self-managed and demercantilized spaces of autonomy , or the relationship of the libertarian world with feminism, environmentalism, anti-militarism and solidarity struggles.
