drifty

One of psychogeography's principle means was the dérive. 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.
Unlike surrealist automatism, the dérive was not a matter of surrendering to the dictates of an unconscious mind or irrational force. Indeed, the situationists' criticisms of surrealism concluded that 'the unconscious imagination is poor, that automatic writing is monotonous, that the whole genre of ostentatious surrealist "weirdness" has ceased to be very surprising'. Nor was everything subordinated to the sovereignty of choice: 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, seeking not only the marvelous beloved by surrealism but bringing an inverted perspective to bear on the entirety of the spectacular world.
