Pierre Bourdieu’s theory of social space, with its corresponding conception of ‘structural relations’, has been a key inspiration for relational sociologists. There is much to commend this theory and Bourdieu’s empirical operationalisation of it, which draws upon the techniques of multiple correspondence analysis, is also important. However, there are serious flaws with the theory. It cannot explain what Bourdieu purports to explain, and it involves an inherent prioritisation of class over other important social relations, such as gender and ethnic relations, which it struggles to incorporate coherently and which have an equal claim to priority. In this chapter, I explore the flaws in Bourdieu’s theory and suggest an alternative model centred upon social interaction, ‘effective relations’ and social networks.
