Experiências Utópicas no Território Fronteiri o do Mercosul e as Alternativas de Sustentabilidade e Desenvolvimento para o Terceiro Milênio

This article aims to find alternatives for development possibilities for a self-sustaining life in the third millennium. It is based on the Jesuit Guarani Missions experience in the region established in the current border areas of MERCOSUR, demonstrates that this experience had a profound impact on modern thought and Montesquieu and Voltaire called it the 'triumph of mankind'. Were established from the Utopia of Thomas More, which is possible by Guaranis 'way of being', their 'search for the land without evil' and especially through their spirituality, which allows the natural thought of being alive after physical death. The Jesuits prioritized an active Christian and integrated with the world, and with the Guarani, they produced reductions that corresponded to an uniform plan established: production was greater than the needs, the fields were well distributed without owners. No city should reduce excessively population, nor to be overpopulated. The merit was a life according to nature. There were no indigent, no one owned anything, they were all rich. It is proposed that this is a middle course between Capitalism and Socialism. Concluded that the planet will be sustainable only with a fraternal and egalitarian society.
