This is the first of five volumes based on the lectures given by Pierre Bourdieu at the Collège de France in the early 1980s under the title "General Sociology". In these lectures, Bourdieu sets out to define and defend sociology as an intellectual discipline, and in doing so he introduces and clarifies all the key concepts which have come to define his distinctive intellectual approach. In this first volume, Bourdieu focuses on the fundamental social processes of naming and classifying the world, the ways that social agents use words to construct social objects and the struggles that arise from this. The sociologist encounters a world that is already named, already classified, where objects and social realities are marked by signs that have already been assigned to them. In order to avoid the naivety and confusion that stem from taking for granted a world that has been socially constituted, sociologists must examine the part played by words in the construction of social things – or, to put it differently, the contribution that classification struggles, a dimension of all class struggles, play in the constitution of classes, including classes of age, gender, race and social class. An ideal introduction to some of Bourdieu's most important concepts and ideas, this volume will be of great interest to the many students and scholars who study and use Bourdieu's work across the social sciences and humanities, and to general readers who want to know more about the work of one of the most important sociologists and social thinkers of the twentieth century.
