This is the inaugural document of the research to which I will consecrate my life: To analyze the conceptual renovation in the Philosophy-Politics of the XXI Century in order to understand the historical-philosophical structure in the light of the problem of the socio-political crises and the horizon of humanity. In an attempt to crystallize this investigation, this paper attempts, with lightness and modesty, to specify the historical-philosophical margins of what will be identified as the XXI century, to analyze and systematize the philosophical-political production around the notion of ideology, and the reader will find several contrasts to identify contributions, structures and deconstructions of ideology today. The assumption of the research focuses on the conceptual renewal and the importance of the renewal of the notion of ideology, considering that, from the conceptual matrix of our contemporaneity, new readings and analysis of the socio-political crises that have been unleashed in several countries are possible.
