Movement research revolves around one basic question: in which measure can one say that bodies move, instead of saying that they are moved? This could be seen as a philosophical question, belonging to speculations about metaphysics and ontology, disqualified long ago. But it is indeed a very concrete question, which-even if generally unacknowledged as such-haunts virtually all of our discourses in social sciences. Although this is a question that Performance Studies are probably better placed to address than any other field of inquiry, I will approach it from a somewhat lateral perspective, provided by the recent upsurge in Attention Studies, revisited here through Randy Martin's attempt to theorize a "social logic of the derivative" (2015).
