With ‘dark room’ I would like to propose a possible reinvention and erotization of the institution from three starting points belonging to three different traditions which are even contradictory. Firstly, the idea of the institution as an architecture of desire that is able to eschew disciplinary instructions, thus assuming the abject spaces of deviant desire. Secondly, Luce Irigaray’s idea of the opacity and the phenomenon of the labyrinth. Finally, Rivera Cusicanqui’s concept of the ch’ixi as a place where white and black can never give birth to a pure colour. From there, I would like to posit the idea of an institution that hosts the danger of desire and the risk of the contagious, confronting its modern disciplinarity and assumed neutral hygiene.
