Epigraph: Let us design an interesting itinerary, one that leaves its optimal talweg and begins to explore a place: one which does not reach a foreseeable resolution, but searches; seems to wander; not deliberate or sure of itself, but rather anxious, off balance and relentless; questing, on the watch, it moves over the whole space, probes, checks things out, reconnoitres, beats about the bush, skips all over the place; few things in the space escape its sweep; whoever follows or invents this itinerary runs the risk of losing everything or inventing; if he makes discoveries, it will be said of his route that he has left the talweg to follow strange attractors (Serres 2008: 271).
