This introduction sets out from the unresolved paradox to be found in the writings of Bourdieu, namely the theoretical impossibility of public sociology and his own sustained practical engagement with publics. I appropriate and develop his concept of the ‘field’ to account for his success as a public sociologist. It requires us to understand that public sociology is only possible at the intersection of two distinct fields – the academic field and the political field. Public sociology proves to be a rather precarious pursuit, then; first, because of competing demands internal to the academic field; second, because of the difficulty in operating at the intersection of the academic and political fields; and third, because of the obduracy of common sense that cannot be easily dislodged, the very attempt often arousing open hostility. Difficult though it may be, the development of its public face will be necessary for the survival of sociology as well as an important ingredient in defending human existence from extinction by market fundamentalism.
