Montesquieu’s Spirit of the Laws (1748) is one of the outstanding works of modern social thought. Durkheim’s Latin thesis (1892) is not only one of the outstanding interpretations of that work, but also a seminal statement of his own ideas on society and on sociological method. It was the companion thesis to The Division of Labour and a forerunner of The Rules of Sociological Method.

This is the first English translation directly from the original Latin text, and also includes the original text, along with full editorial notes, a related article by Durkheim on Hyppolite Taine and a commentary on Durkheim and Montesquieu by W. Watts Miller.
