Book excerpt: This collection of recent essays by the influential sociologist Herbert J. Gans brings together the many themes of Gans’s wide-ranging career to make the case for a policy-oriented vision for sociology. Sociology and Social Policy explicates and helps solve social problems by presenting a range of studies on what people, institutions, and social structures do with, for, and against one another. These works from across Gans’s areas of interest—the city, poverty, ethnicity, employment and political economy, and the relationship between race and class—together make a powerful call to action for the field of sociology.
