This is a place holder for me. In looking at Gramsci and his scant references to intermediate strata, I found this:
“…it is important to study how ppermanent collective wills are in fact formed and how these wills set themselves concrete goals that are both immediate and intermediate-in other words, how they set themselves a collective course of action. This has to do with processes of development that are more or less long; sudden, ‘synthetic’ explosions are rare. ‘Synthetic’ explosions do occur, but looking at them closely one sees that they are more destructive than constructive; they remove external and mechanical obstacles to autochthonous and spontaneous development-the Sicilian Vespers can be taken as an example “.
