Austrian philosopher, economist and member of the Vienna Circle, Otto Neurath (1882–1945) investigated representational maps for more than two decades of his life.In search of “humanizing knowledge” he revolutionized the discipline of chart making by quantitative maps (picture statistics) accessible to a large public. In this book, Sophie Hochhäusl argues that Neurath’s map “City Planning” served not only as one of the first accessible socio-political maps of a city, but it was in effect also a heuristic architectural device. Hochhäusl also explores the extent to which Neurath perceived of the city as an agglomeration of social facts, and how far his socio-political map contributed to planning the city on such basis.With a preface by Bart Lootsma.
