This book differs from much of the existing literature of modernity in its attention to a variety of individuals who are not generally recognized as major intellectual figures in their own right, or even as notable representatives of important scientific, philosophical, or aesthetic tendencies. Instead, the author deals with the ways ideas were transmitted within the French elite, and how they were transformed to suit the needs of their users once they were taken up in settings outside the immediate precincts of official high culture and the inner circle of the Parisian avant-garde. The book analyzes the elites’ response to a series of challenges to the old order: the establishment of mass democracy, the new role of workers and the middle classes in shaping public opinion, burgeoning technological possibilities, and, most importantly, the rise of American-style consumer capitalism. The author shows how business and commercial elites tried simultaneously to appropriate and divert these new forces, balancing tradition with a cautious acceptance of various elements of modernity. The author explores this terrain by focusing on the changing character of advertising, the evolution of the French press, the growth of scientific management, the role of the Social Catholic movement in opening up different kinds and channels of mass communication, and the development of ideas of state planning and industrial rationalization.
