According to the social critic Guy Debord , the most rewarding walks start without a preconceived route or destination. Instead, you should simply drift through the urban landscape by submitting to “the path of least resistance that is automatically followed in aimless strolls.”
The point is to keep your eyes open and note the way the different neighbourhoods or quartiers produce varied and specific psychological effects in you, the walker, as you execute your derive or drift. Only in this way, will you truly get to know the city; only in this way, will you succeed in penetrating at least part of its mystery.
