Breton notes: 'Quietly. I want to pass where no one yet has passed, quietly! ' After you, dearest language.' Language takes precedence. Not only before meaning. Also before the self... the writings of this circle are not literature but something else 'demonstrations, watchwords, documents, bluffs, forgeries if you will... what is the programme of the bourgeois parties? A bad poem on springtime, filled to bursting with metaphors. The socialist sees that 'finer future of our children and grandchildren' in a condition in which all act 'as if they were angels', and everyone has as much 'as if he were rich', and everyone lives 'as if he were free'. Of angels, wealth, freedom, not a trace. These are mere images... Only when in technology body and image so interpenetrate that all revolutionary tension becomes bodily collective innervation, and all the bodily innervations of the collective become revolutionary discharge, has reality transcended itself to the extent demanded by the Communist Manifesto.
Emphasis mine. I find the essay too impenetrable to quickly read, especially its reference to physis and technology.
Are surrealism's "mere images" here said by Bajamin to be in some sense meaningless? They are opposed to "metaphor", presumably then lacking a tenor, are not being compared to anything, and surely Benjamin also means they don't exist. That to me seems to imply they lack any concrete reference.
So, is Banjamin saying, when he says that the image must combine with the body, that international socialism would revolutionise our "bodies" as if that had no referent?
