• Sommario/riassunto: Georges Friedmann est une figure à redécouvrir. À l’occasion du centenaire de sa naissance, le présent ouvrage retrace la trajectoire de l’homme avant, pendant et après la Seconde Guerre mondiale. Écrivain, voyageur, résistant, étranger à la tradition durkheimienne, marxiste plus spinoziste qu’hégélien, Friedmann a su faire partager ses curiosités et ses inquiétudes pour relancer la sociologie après la guerre. Dès la fin des années 40, tournant le dos à la Sorbonne, s’appuyant sur des institutions comme le CNRS et le Conservatoire National des Arts et Métiers, il met le pied à l’étrier à une nouvelle génération qui s’emploie à développer la sociologie hors de la clôture académique. À l’articulation de l’histoire intellectuelle et de l’histoire de la sociologie, ce livre est bâti en trois parties : histoire, œoeuvres, témoignages. Il fait dialoguer ceux qui furent ses proches dans la refondation de la sociologie et les membres d’une nouvelle génération qui, n’ayant pas connu directement Georges Friedmann, se sentent plus libres pour réinterroger l’œoeuvre.
