Psychogeography. Increasingly this term is used to illustrate a bewildering array of ideas from ley lines and the occult, to urban walking and political radicalism. But where does it come from and what exactly does it mean? Psychogeography is the point where psychology and geography meet in assessing the emotional and behavioural impact of urban space. The relationship between a city and its inhabitants is measured in two ways - firstly through an imaginative and literary response, secondly on foot through walking the city. From Urban Wandering to the Society of the Spectacle, from the Drive to Dtournement, Psychogeography provides us with new ways of apprehending our surroundings, transforming the familiar streets of our everyday experience into something new and unexpected. This guide conducts the reader through this process, offering both an explanation and definition of the terms involved, an analysis of the key figures and their work as well as practical information on Psychogeographical groups and organisations.
