The Urban Condition – Essays on the Geopolitics of the City is an eloquent demonstration of the relevance and richness of analyzing physical space for understanding certain phenomena, a dimension often neglected in studies produced by the social sciences. This work requalifies the importance and scope of contemporary geography, especially with regard to interpretations of sociopolitical dynamics. In this sense, citizenship, sovereignty, and public space are some of the categories reconsidered in light of their relationship with spatiality. The author seeks, first and foremost, to construct general categories that express ways of conceiving space, nomospace, and genospace. From there, he examines, in several instances, how these categories can help us reflect on the idea of rights and duties, and how this idea materializes in physical and behavioral forms at various times and places in urban life. The title The Urban Condition expresses the conception that the city is the combination of a certain social structure with a precise physical form. One cannot exist or be understood without the other, and therefore, the examination of urban dynamics must necessarily also focus on the physical layout or, in other words, the geographic dimension of these phenomena.
