This book is both a conceptualization and detailed analysis of the current crisis in which modern utopian categories of political institutions find themselves, as well as a reflection and clarification of the new dangers and opportunities facing post-utopian politics in-the-making. Met with those who believe that no more utopian political projects are possible, the post-utopian movement maintains a non-fantastic or illusory character of being able to apply new great discourses and radically democratic historical narratives, while respecting both the autonomy and emancipation of individuals as plurality and the socio-cultural differences of communities. With this purpose in mind, the book is divided into five thematically differentiated sections: the new utopian categories beyond modern epistemes; the possibility of liberal utopian democracies without neoliberalism; the opportunities of socialist empowerments and insurgencies; the necessity of thinking in the space between two ages; andthe urgency to create eco-political post-utopias.
