Georges Sorel
With his book "Il socialismo", published in 1884 in Catania, he became one of the first theoreticians of the Italian workers movement. His socialism was not based on the scientific Marxist approach, but was closer to the ideology of Mazzini – one of the fathers of Italian unification – with some influence of French utopian thinkers such as Georges Sorel, and in terms of practical politics resulted in a kind of radical-democratic reformism.
