Psychology in the human sciences in France, 1920-1940: Ignace Meyerson's historical psychology

Between World War I and World War II, psychology adopted a direction open to human sciences; I. Meyerson was the main organizer of this choice. Leading the Societe de Psychologie and the Journal de Psychologie Normale et Pathologique, he tried to construct an individual and collective psychology that reflected not only the scientific preoccupations of his masters and friends but also their political choices: They had been the founders of the Human Rights League at the end of the 19th century. Behind Durkheim and Seignobos, with Mauss, Levy-Bruhl, and Blondel, Meyerson answered the new historians' call for a unified science of "mentalities," a historical psychology of collective representations. Meyerson offered to sociologists, anthropologists, linguists, and historians several forums to debate in which psychology was the unifying science. But at the end of the World War II, his psychology was marginalized, and a postivistic and behavioristic way was preferred. Meyerson's historical psychology disappeared from academic psychology, but historians have preserved its legacy.
