Book excerpt: First published in 1980, this book presents a study of knowledge and the patterns of social and scientific thought. Keith Dixon argues that traditional and contemporary formulations of the sociology of knowledge involve a series of fallacies, and the claim to reduce knowledge to ideology devalues the role of reasoned inquiry. Chapters discuss such areas as the theories of Marx and Mannheim, the sociology of science and of religious belief. With a detailed conclusion analysing the foundations and limits of the sociology of knowledge, this reissue will provide an interesting and useful analysis for students of Sociology.
