摘要:This paper aims to demonstrate how the post-modern narratives contributed to the formulation of distortions in the paradigm of efficiency and democracy. Regarding the methodology, the deductive method was applied, with bibliographic analysis, studying the theoretical context of post-modernity, to understand its consequences. We conclude that democracy must rescue constitutionalism as a basis for legitimacy, removing the demand for efficiency in this role, under consequence of weakening democracy itself. Therefore, the innovation of the text lies in establishing the systematization and correlation between postmodernity, efficiency and deliberative democracy.
