A partir de uma discussao sobre a estrategia de manifestacao politica conhecida como “ocupacao”, e de exemplos oriundos de pesquisas realizadas em espacos publicos da cidade do Rio de Janeiro, este artigo propoe uma nova perspectiva sobre esta oposicao, ainda dominante na bibliografia. Palavras-chave : espaco publico; ocupacao; sociabilidade. ABSTRACT The political activation of public spaces is commonly associated with their extraordinary mobilization by large social movements. On the contrary, a strong political significance is rarely attributed to the everyday and ordinary use of these spaces. Based on a discussion about the strategy of political manifestation known as “occupation” and presenting examples from research carried out in public spaces in the city of Rio de Janeiro, this article proposes a new approach to this opposition, still dominant in academic literature. Keywords : public space; occupy; sociability.
