This volume contains an all-new collection of penetrating works by modern social scientists on Karl Marx, Emile Durkheim, and Max Weber -- the "holy trinity" of sociology and other social sciences. --Although their paradigm-changing treatises were first published between the mid-19th and early 20th centuries, they contain ideas and methods that still largely define what social scientists think about, and how they analyze societal phenomena, in the disciplines of sociology, economi--cs, political science, education, geography, anthropology, and social psychology. How do social scientists in the late 20th and early 21st centuries conceive of the great masters's concepts, methods, and findings? Have modern intellectual, technological, and sociopolitical trends and events -- such as postmodernism, multiculturalism, the Internet, globalization, and feminism -- affected the way social investigators use and dissect Marx, Durkheim and Weber? Do findings from recent studies tend to validate or discredit the work of the classical theorists? These and related questions are answered in this anthology, which assembles for the first time a rich collection of 18 works by contemporary social scientists. Collectively, they clearly show how leading theorists and researchers apply and analyze concepts such as class, anomie, bureaucracy, rationality, representations, capitalism, charisma, inequality, and religious ritual, which are at the heart of the writings of Marx, Durkheim, and Weber.
