His early American works opened new vistas in rural sociology, social stratification, and theory. They provided all elegant standard for scientific sociology and won him the founding chairmanship of sociology at Harvard University. A constant innovator, he next explored the vast expanse of human affairs, and outlined the surfacing crisis of modernity. At the Harvard Research Center for Creative Altruism he developed a blueprint for social reconstruction. Such interests combined with a prophetic and combative style of disagreement drove him to the margins of a discipline hungry for acceptance as a science. In the early 1960s, his work was once again recognized, and he became president of the American Sociological Association.

Including essays that range from his early Russian years to his final works in the 60s, this collection provides a much-needed introduction to one of sociology's most controversial thinkers.
