"That is why so many Sorelians, like many people on the Left both before and after the war, slid into fascism. When these leftists of all shapes and colors came to the conclusion that the working class had definitely beaten a retreat, they did not follow it into this attitude. Their socialism remained revolutionary when that of the proletariat had ceased to be so. Having to choose between the proletariat and revolution, they chose revolution; having to choose between a proletarian but moderate socialism and a nonproletarian but revolutionary and national socialism, they opted for the nonproletarian revolution, the national revolution."

“a variety of socialism which, while rejecting Marxism, remained revolutionary. This form of socialism was also, by definition, anti-liberal and anti-bourgeois, and its opposition to historical materialism made it the natural ally of radical nationalism.”

“It was the revolutionary syndicalists, those dissidents and nonconformists of the Left, who by means of their criticism of Marxist determinism created the first elements of the Fascist synthesis in the first decade of our century.”

“Like all self-respecting revolutionaries, Mussolini considered himself a Marxist. He regarded Marx as the ‘greatest theoretician of socialism’ and Marxism as the ‘scientific doctrine of class revolution.’”

“Thus, fascism adopted the economic aspect of liberalism but completely denied its philosophical principles and the intellectual and moral heritage of modernity.”

“If the Fascist ideology cannot be described as a simple response to Marxism, its origins, on the other hand, were the direct result of very specific revision of Marxism. It was a revision of Marxism and not a variety of Marxism or a consequence of Marxism...It was the French and Italian Sorelians, the theoreticians of revolutionary who made this new and original revision of Marxism, and precisely this was their contribution to the birth of the Fascist ideology.”

“At the same time as Sorel, the revolutionary syndicalists in Italy came to this conclusion: they threw themselves enthusiastically into the war not out of patriotism, as is often thought, but because they saw it as an instrument of revolution. Since war is a conflict between nations rather than between classes, the nation was seen as the foremost agent of revolution, and Italian revolutionary syndicalism became the backbone of fascist ideology.”
