This thesis is organized from three essays – Language as untranslatable, Rivers that communicate and Future of the Past – that focus in relevant questions of the writer José Luandino Vieira work. The aim is to identify, in some of his books, how language is used by the author in his fiction, as a tool to create political utopian spaces; beginning during the time of fighting for Angola s independence, in the second half of the twentieth century, till the first decades of the twenty first century. It intends also to show how his search for utopia continues through time, and has not stopped with the end of the national independence war. The search for justice and social inclusion gain life as utopias, expressed above all in the language adopted by the author. In the first chapter of this dissertation, I talk about his investment in language and how is this crucial for his literature and his world Project. In the second, I talk more broadly about how the river – that comes and goes, disappears and reaches back to existence – is a subject presente in both, Guimarães Rosa and Luandino, following a genealogy of language creators, but with more in common than just that. In the third, I talk in-depth about the political issues raised in his texts and his intentions.
