Praise for the First Edition: 'Totally reliable! the authors have produced a book urgently needed by all those charged with introducing students to the classics! quite indispensable' - Times Higher Education Supplement This is a fully updated and expanded new edition of the successful undergraduate text. Providing a lucid examination of the pivotal theories of Marx, Durkheim and Weber, the authors submit that these figures have decisively shaped the discipline. They show how the classical apparatus is in use, even though it is being directed in new ways in response to the changing character of society. Written with the needs of undergraduates in mind, the text is essential reading for students in sociology and social theory.
