Enquanto a pergunta era inicialmente vaga, com base no diálogo fornecido (após a confirmação do pôster original), uma pesquisa no Google por uma parte desse diálogo me leva a esta citação / nota de rodapé no livro de Fabrizio Cilento “Um cinema investigativo: política e modernização no cinema italiano, francês e americano” 2018; página 66 número do item 32:
A menção de "Marcuse" nessa peça me levou a este 2010 LA Times peça de Dennis Lim intitulada “'Dillinger Is Dead' faz uma declaração política"
At his workplace, Glauco listens to a colleague reciting from an essay that compares the isolation gas chamber to "the condition in which modern man lives" before going on to introduce the concept of "one-dimensional man," popularized by the philosopher Herbert Marcuse a few years before the film was made.
O que me leva ao livro 1964 de Herbert Marcuse Homem unidimensional que a Wikipedia descreve como:
One-Dimensional Man: Studies in the Ideology of Advanced Industrial Society is a 1964 book by the philosopher Herbert Marcuse, in which the author offers a wide-ranging critique of both contemporary capitalism and the Communist society of the Soviet Union, documenting the parallel rise of new forms of social repression in both these societies, as well as the decline of revolutionary potential in the West. He argues that "advanced industrial society" created false needs, which integrated individuals into the existing system of production and consumption via mass media, advertising, industrial management, and contemporary modes of thought.
Se esse livro não for a fonte desse diálogo, eu ficaria bastante chocado.
