Notes on the dead-end is a performed conference about dead-end road signaletics I gave at SB34-Clovis (Brussels). I analyzed that symbol under a semiotic and historical perspective, mobilizing sources from Hegel, T.S. Eliot, Jacques Lacan and Hartmut Rosa. Social acceleration and fear of the end of the world lead us to a kind of affective «dead-end», a mixed feeling of anguish and despear about the future. Some people called it «eco-anxiety». My point was to show how that designation was actually part of a larger process of depolitisation, tending to reduce global warning to individual responsability.
