Abstract
In the inter-war period Italian philosophical culture was dominated by idealistic, spiritualistic and religious brands of philosophies, among which Benedetto Croce’s and Giovanni Gentile’s kinds of idealism were the prevailing ones. These idealistic philosophies were characterized by a strong aversion for positivistic, pragmatist and scientific philosophies which, in the first decades of our century, were represented in Italy above all by Giovanni Vailati, Mario Calderoni , Giuseppe Peano and Federigo Enriques. Italian ‘scientific philosophy’ lost in the battle with Croce’s and Gentile’s idealistic philosophies. On the political level, the hegemony of Croce and Gentile coincided with the years of Fascist dictatorship . On the cultural level, this hegemony caused the suppression of scientific culture and philosophy in comparison with humanistic culture, and the subsequent philosophical isolation of Italy from the majority of the movements of scientific philosophy working in those years in the other European countries and in the United States of America
