In philosophy, a Dérive is a French concept meaning an aimless walk, probably through city streets, that follows the whim of the moment. It is sometimes translated as a drift. French philosopher and Situationist Guy Debord used this idea to try and convince readers to revisit the way they looked at urban spaces. Rather than being prisoners to their daily route and routine, living in a complex city but treading the same path every day, he urged people to follow their emotions and to look at urban situations in a radical new way. This led to the notion that most of our cities were so thoroughly unpleasant because they were designed in a way that either ignored their emotional impact on people, or indeed tried to control people through their very design. The basic premise of the idea is for people to explore their environment ("psychogeography") without preconceptions, to understand their location, and therefore their existence.
