Beginning with women's experience, the author examines the field's actual practices of reasoning and conceptualization. She argues that standard sociological methods of inquiry make use of ideological practices, transforming the actualities of people's lives into a formalized picture lacking subjects and subjectivity. The method of Smith recommends anchors a Marxist materialism, based in people's activities, to a woman's stand-point based in experience. She uses this method in a radically original way to explore ideology and objectified knowledge as the conceptual practices of ruling. Smith is equally concerned with the application of sociological ideology to the human service bureacracy and the way institutions of mental health reconstruct women's lives. She provides meticulous accounts of the ways in which police reports, government statistics, hospital records, and pschiatric files are ideologically interpreted, transforming a person's life history in the process. In a revelatory chapter on the biographer Quentin Bell's account of Virginia Woolf's suicide, the author demonstrates how the text implicates the reader in the objectification of Woolf's "psychiatric problems." Highly critical of current sociological practices, The Conceptual Practices of Power both recommends and exemplifies the alternative approach that Smith presented in her earlier work, That Everyday World as Problematic, also published by Northeastern University Press.
