The purpose of this paper is to explore and develop understandings of philosopher-sociologist Henri Lefebvre’s approach to communication. Lefebvre wrote extensively on everyday life, semiotics, the state, globalisation, and space and time, and these remain vital areas of investigation. As Lefebvre’s influence has filtered through to contemporary discussions within communication studies of a ‘spatial’ or geographical turn, it seems appropriate to re-situate his writings on communication within his key philosophical and sociological principles. The article discusses: dialectics, space and time, everyday life, his perceived-conceived-lived triad, his approach to semiotics, the concept of the semantic field, and his later – and crucial – theory of texture. Finally, the discussion shifts to globalisation and explores the relationship between his approaches to communication and the development of the nation-state and the world market. The article aims to provide a resource for communication scholars and social scientists looking to engage with his sociological approach to communication.
