One of psychogeography's principle means was the dérive. by Dr Andrew Evans
The dérive is a stroll through the city by several people who are out to understand the "psychogeographical articulation of the modern city". The strollers attempt an interpretive reading of the city, an architectural understanding. They look at the city as a special instance of repressed desires.
Long a favorite practice of the dadaists, who organized a variety of expeditions, and the surrealists, for whom the geographical form of automatism was an instructive pleasure, the dérive, or drift, was defined by the situationists as the 'technique of locomotion without a goal', in which 'one or more persons during a certain period drop their usual motives for movement and action, their relations, their work and leisure activities, and let themselves be drawn by the attractions of the terrain and the encounters they find there'. The dérive acted as something of a model for the 'playful creation' of all human relationships..to dérive was to notice the way in which certain areas, streets, or buildings resonate with states of mind, inclinations, and desires, and to seek out reasons for movement other than those for which an environment was designed. It was very much a matter of using an environment for one's own ends. Read all, via Dr Andrew Evans
