The term ”psychogeography” is used to illustrate a bewildering array of ideas, from ley lines & the occult to urban walking & political radicalism--where does it come from & what exactly does it mean? Psychogeography is the point where psychology & geography meet in assessing the emotional & behavioral impact of urban space. The relationship between a city & its inhabitants is measured firstly through an imaginative & literary response, secondly on foot through walking the city. This creates a tradition of the writer as walker & has both a literary & a political component. This guide examines the origins of psychogeography in the Situationist Movement of the 1950s, exploring the theoretical background & its political applications as well as the work of early practitioners. It offers both an explanation & definition of the terms involved, an analysis of the key figures & their work, & practical information on psychogeographical groups & organizations.
