The annual Hettner-Lecture series is devoted to new theoretical
developments in the crossover fields of geography, economics, the social
sciences, and the humanities. David N. Livingstone presented during the
fifth Hettner-Lecture two lectures entitled 'Knowledge, space and the
geographies of science' and 'Tropical hermeneutics and the climatic
imagination', both of which are published in this volume in revised
form. In the interview with Michael Hoyler, Tim Freytag and Heike Jons,
David N. Livingstone talks about geographical traditions and his
development as a geographer and his research interests.
