The Discourse and the Capitalist. Lacan, Marx, and the Question of the Surplus

In the seminar XVI, Dun Autre a l'autre, in 1968/1969, Jacques Lacan claimed that there is an homology between the function of object a in the unconscious and the Marxian notion of surplus-value. Both concepts in fact revolve around similar axes: their reluctance to be localized in a certain place of the structure and their connection with the notion of surplus. In Chapter 7 of Dos Kapital, Marx seems to imagine a purely mythical pre-capitalist society where production is only devoted the pure satisfaction of basic survival needs and where labour is still controlled by the worker according to a certain purpose: with the irruption of the surplus in the capitalist mode of production the very qualitative dimension of the production and reproduction of commodities and human beings is commanded and organized by the pure drive of abstract accumulation. In order to rearticulate the incessant capitalist drive for abstract wealth, the symptom relies on the unsurpassable contradiction between labour-power and living-labour: essential in order to enable every cycle of accumulation, but at the same time its inevitable obstacle.
