"The principle of the ‘derive’ … deliberately sets out to create ‘randomness’ that allows situations to arise that can give insight and creativity. A dérive is an aimless ‘stroll’ around an urban environment with no particular direction or wish to ‘get anywhere’. This device was originally used by the Surrealists to experience aspects of the Unconscious projected on the environment. The result was to experience psychic qualities or atmospheres from the buildings/geography that taps into hidden aspects of the psyche. For example one might view the whole of London as representing the whole of the psyche. Someone who lives and works in London will only ever experience certain very specific areas used habitually for work, play and home etc. These areas attract states of consciousness that make up the facets of personality. By deliberately setting out to visit a part of the city that one has never been to before and explore it in a random way is to open up to new aspects of consciousness that the geography evokes - by mood, atmosphere, or synchronicity. The randomness helps stifle the conscious mind from attaching familiar associations to the unknown area thus allowing ‘otherness’ to arise. The Situationist movement went along with the idea that environment can be a source of new experiences and creativity but said that the Surrealists were wrong to claim the source as being the Unconscious. They claimed that it was the situation itself that produced the new creativity or consciousness." ~ M.M. (via Phil Hine)
