The closest Blanqui comes to writing anything explicitly similar to his earlier insurrectionary writings is the swipe at Haussman. Yet, the whole theory of eternal return is a revolutionary theory. As pointed to in the excellent introduction, Blanqui's theory absolves the insurrectionary failures of the past, because in the future we will win.
I'm only partially on board with the idea of eternal return; the biggest struggle for me is reconciling my own individuality (this word doesn't fully convey what I'm reaching for) with the concurrent existence of there being someone exactly the same. I don't want to speak quite in terms of a "soul" or reincarnation, but there is a cognition I have that has no recollection, knowledge, or shared experience with anything else, and it becomes difficult to fathom how I can be the exact same as another's existence without sharing some sort of mental environment.
Relating this to Benjamin's Theses, this is the theory that blasts open the continuum of history. Even if we have lost every struggle in the past, there is no progress because everything is always re-occuring, and in some world, in some formulation--maybe this one we/I experience--we will win the next one.
