Professor John Rex was one of Britain's most eminent sociologists, and a teacher of a whole generation of sociology students. In this book he presents a stimulating introduction to the major issues of sociological theory and gives an account of the perspective which has informed his thinking and writing. He deals with the objectives of sociological investigation, the methods it uses and how in these respects it resembles or differs from natural science and history. He goes on to discuss the work of Weber, Durkheim, Marx, Engels, Mills and other important theorists, and concludes with a convincing demonstration of the continuing relevance of the Weberian tradition to the study of sociology.
