This paper is a contribution to the small but growing body of scholarship dedicated to a reappraisal of German occultism in the period prior to the Second World War. Moving beyond those analyses of the German occult movement which have viewed it solely in terms of its links--often tenuous--to National Socialism, this paper considers German occultism, specifically parapsychology, as a mode of cultural critique utilised by Germans from across the political spectrum. Concentrating on the experimental study of materialisation and its (...) theorisation as "supernormal biology," this paper argues for strong links, forged primarily by the biologist, philosopher, and neo-vitalist Hans Driesch, between parapsychology, as a way of understanding life and mind, and epistemological reforms within biology and psychology. It argues, furthermore, that for Driesch, as for a number of European scholars, parapsychology provided scientific validation of a belief in the naturalness of liberalism and pacifism. (shrink)
