Solidarity: The Social History of an Idea in Nineteenth Century France1

The survival of a concept is generally only secured at the price of an intellectual odyssey in the course of which it is transformed out of all recognition. The nineteenth century fortunes of the idea of solidarity exemplify this axiom only too strictly. It became the victim of a multiplicity of ingenious puns and metaphors as well as outright malicious distortions that rendered a simple, technical word, drawn from the sphere of jurisprudence, at once emotive and obscure, influential and diffuse. As the eminent and caustic critic of the twentieth century, Julien Benda, formulated this vital problem of the fate of concepts, “pour l'historien des idées des hommes, la réalité ce n'est point ce qu'ont été les idées dans l'esprit de ceux qui les ont inventées, mais ce qu'elles ont été dans l'esprit de ceux qui les ont trahies… car il est clair qu'une doctrine se propage d'autant plus largement qu'elle est apte à satisfaire un plus grand nombre de sentiments divers.” This pessimistic view has been all too frequently verified in human history.
