Book excerpt: The relationship between sociology and social critique has haunted the discipline since its origins. Does critique divert sociology from its scientific project? Or is critique the ultimate goal of sociology, without which the latter would be a futile activity disconnected from the concerns of ordinary people? This issue has underpinned two divergent theoretical orientations that can be found in the discipline today: the critical sociology that was developed in its most elaborate form by Pierre Bourdieu, and the pragmatic sociology of critique developed by Luc Boltanski and his associates. In critical sociology, description in terms of power relations underscores the potency of mechanisms of oppression, the way the oppressed passively endure them, going so far in their alienation as to adopt the values that enslave them. Pragmatic sociology, by contrast, describes the actions of human beings who rebel but who are endowed with reason. It stresses their ability, in certain historical conditions, to rise up against their domination and construct new interpretations of reality in the service of critical activity. In this major new book Boltanski develops a framework that makes it possible to reconcile these seemingly antagonistic approaches - the one determinist and assigning the leading role to the enlightening science of the sociologist, the other concerned to stick as closely as possible to what people say and do. This labour of unification leads him to rework central notions such as practice, institution, critique and, finally, ‘social reality,' all with the aim of contributing to a contemporary renewal of practices of emancipation.
