While other academic disciplines claim to focus on specific subject matter, sociologists think of their field as an approach to understanding the often invisible forces and social contexts that shape the way people conduct their lives. How those forces and contexts are structured is central to sociology. But how do sociologists analyze these invisible structures? This book contributes to our understanding by bringing together a remarkable set of master essays about modern sociology written by some of the leading figures of the field. Each author describes a vision of sociological inquiry or offers an example of research that illustrates approaches and problems encountered in doing sociological work.
