It is necessary to distinguish between socialism and socialism-in fact, between idea and idea of the same socialist conception, in order to distinguish among them those that are inimical to Fascism. It is well known that Sorellian syndicalism, out of which the thought and the political method of Fascism emerged-conceived itself the genuine interpretation of Marxist communism. The dynamic conception of history, in which force as violence functions as an essential, is of unquestioned Marxist origin. Those notions flowed into other currents of contemporary thought, that have themselves, via alternative routes, arrived at a vindication of the form of State-implacable, but absolutely rational-that finds historic necessity in the very spiritual dynamism through which it realizes itself.
