This book presents classical articles influencing the field that appeared in The Insurgent Sociologist, along with current reflections by the original authors. These selections reflect radical sociology’s continuing interest in capitalist development, class, race, gender, and power. The introduction contextualizes the role of The Insurgent Sociologist in the development of a radical sociology and its impact on the discipline. The conclusion provides an agenda for how the next version of critical sociology should relate to and strengthen the heterogeneous world of civil society. Never have so many prominent sociologists provided such a rare intellectual treat by being so frank about their own past work, and then suggest how we can do better in the future to provide frameworks for a critical and relevant sociology.
