[The marvels of the incarnated man. Victor Melcior and the redefinition of mediumship (1901)].

Towards the end of the 19th century, new medico-psychological approaches were applied to mediumship through the scientific study of spiritualist phenomena. The spiritualist idea of the medium was replaced with the notion of the medium as an unstable human being capable of emanating psychic forces unconsciously. This paper analyses the redefinition of mediumship through the polemical articles of the Catalan physician Victor Melcior. On one hand, this microhistory allows the local debate to be placed within the scientific international context, describing the relationships among spiritualism, medicine and psychopathology at that time. On the other hand, it permits analysis of the reactions of some spiritualists to Melcior's theories and of the consequences of this debate for spiritualism in general.
