“This phenomenon was a central fact in the history of Italy. It was the great movement of transformation of the Italy of the early 1960s, what we call the economic miracle that transformed Italy.

Florentine Italian was used on rare occasions by few people, and it was necessary to invent a common language so we could understand each other … a writer could not ignore this, could not fail to involve himself in this phenomenon.”
