Résumé : At a time of radical uncertainty, with our future under threat, a small constellation of Brussels-based associations and activists have set out to explore otherwise possible futures. Against powerlessness, against the ineluctable – but through what is at the core of their struggles for technological, environmental, and social justice – they have com- posed worlds, cultivated dissenting futures and crafted stories that they share here like a bottle to the sea, as an invitation to join this makeshift vessel of imagination.
