Claves epistemológicas para descifrar el derecho a la ciudad de Henri Lefebvre

The article presents the need for urban critical theory to shape a small space of hopes, in the midst of a global crisis, urbanizing of neoliberalism and urbanism crisis as such. Consequently, and in attempt to expand the field of urban theory, it shows one of the first steps in the doctoral research of the author, in which, through the epistemological survey on essential fields of Henri Lefebvre's thought, is intended contributing to a true understanding of the right to the city, proclaimed in 1968 and today become slogan systematically. The analysis arises from the notion of radical human space as original restoration of the young Lefebvre's thought between 1939-1958 and delves into what author considers the clue in the complete works of Lefebvre, the critique of everyday life.
