No concept attracted as much controversy, or muddled ideological identifications so thoroughly, as ‘myth’ in interwar France. By the late 1930s, ‘la mythomanie’ was drawing systematic attention from existentialists, Surrealists, ethnologists, sociologists, and nascent fascist movements. This essay reconsiders this polemical and misunderstood moment in interwar thought. It focuses on the intellectuals most central to its notoriety: the members of the Collège de sociologie and their fascination with Georges Sorel. Though interwar mythomania has long been treated as an antiparliamentary cultural (...) politics designed to secure enthusiastic mass conformity, this essay argues that such accounts are incomplete. They misunderstand the deeper philosophical debate unfolding about the conditions of revolutionary agency in a desacralized society. Bringing this debate back into focus helps liberate mythomania from historiographic commonplaces. It emphasizes how, for better or worse, many of those who advocated for new political myths aimed to spur human agency, not confiscate it. (shrink)
