Between the 1960s and the 1970s, Marxism reached its maximum success in Italy, but that phase also corresponded to the crisis of the Italian Communist Party’s cultural hegemony, challenged by both the attacks coming from the New Left and innovative readings of Marx’s works. Marxist historicism, on which the Italian Communist Party had based its cultural policy after the the Second World War, consequently suffered heavy attacks. This article illuminates one of the responses to historicism’s decline, providing an account of (...) the book series La Scienza Nuova, issued by the publishing house Dedalo in Bari and edited by the communist intellectual Mario Spinella, who was able to remain loyal to his party demonstrating, at the same time, cultural autonomy. Also grounding on archival documents, the article posits that Spinella’s aim was to attract New Left readers by selecting books on topics and by authors that were in fashion in Italy and abroad, but incorporating them into a theoretical framework based on Marxist historicism, in order to preserve the latter in an evolving cultural environment.
