Stiegler argues that today the proletarian must be reconceptualized as the economic agent whose knowledge and memory are confiscated by machines. By bringing together Plato and Marx, Stiegler can show how a generalized proletarianization now encompasses not only the muscular system, as Marx saw it, but also the nervous system of the so-called creative workers in the information industries. This short text offers an excellent introduction to Stiegler's work while at the same time representing a political call to arms in the face of a deepening economic and social crisis.
