At the same time as being enveloped in this fantastic Rhizomitic Learning MOOC am reading…’Semblance and Event: Activist Philosophy and the Occurrent Arts.’ by Brian Massumi, which perhaps goes some way in answering the problem of the ‘Wall?’

‘Events are always passing; to experience an event is to experience the passing. But how do we perceive an experience that encompasses the just-was and the is-about-to-be as much as what is actually present? In Semblance and Event, Brian Massumi, drawing on the work of William James, Alfred North Whitehead, Gilles Deleuze, and others, develops the concept of “semblance” as a way to approach this question. It is, he argues, a question of abstraction, not as the opposite of the concrete but as a dimension of it: “lived abstraction.” A semblance is a lived abstraction.’
