Some of the most important questions of the social sciences in the twentieth century have been posed by scholars working at the intersections of social theory and history viewed on a grand scale. The core essays of this book focus on the careers and contributions of nine of these scholars: Marc Bloch, Karl Polanyi, S. N. Eisenstadt, Reinhard Bendix, Perry Anderson, E. P. Thompson, Charles Tilly, Immanuel Wallerstein, and Barrington Moore, Jr. The essays convey a vivid sense of the vision and values each of these major scholars brings (or bought) to his work and analyze and evaluate the research designs and methods each used in his most important works. The introduction and conclusion discuss the long-running tradition of historically grounded research in sociology, while the conclusion also provides a detailed discussion and comparison of three recurrent strategies for bringing historical evidence and theoretical ideas to bear upon one another.
