"This volume assembles twelve texts published between 1892 and 1915 . . . . The editors allow one to see the genesis of the ideas of Duhem, philosopher and historian, of the variety of his styles, and sometimes also the limits of his work . . . . A useful index, probably unique in the field of Duhemian studies, completes the book . . . . The English-language public may be assured an exemplary translation and a reliable critical apparatus." --Jean Gayon, Revue d'Histoire des Sciences
