Anyway, in Italy, Pragmatism became an obsession among the early nationalist intellectuals who helped lay the ground work for fascism. Mussolini said more than once that William James was one of the three most important philosophical influences in his life (though he was probably embellishing for American audiences). He sold many of his policies as applications of William James' idea of the "moral equivalent of war" — just as FDR had done with his New Deal.
Moreover, Georges Sorel, the philosophic father of both Italian Fascism and Leninism, was a devout follower of James. It's been said many times that Sorel's great accomplishment was to marry James' "Will to Believe" and Nietzsche's "Will to Power." Moreover, the influence worked both ways.
The relationship between Pragmatism and Statism is hard for some to see at first blush. But it boils down to the fact that the Progressives used Pragmatic philosophy (correctly or not) to destroy the Old Order of liberal democracy.
