In fin-de-siècle France, we witness a strange circulation of concepts between philosophy, theoretical and experimental psychology, and the borderline realm of what we would now call meta- or parapsychology. This was a time characterized by a complex process of redefinition of the disciplinary frontiers between philosophy and psychology, which favoured the birth of hybrid conceptualities and stark oppositions as well. Furthermore, the great scientific advances in physics, physiology, and psychology fostered hope for a full rational explanation of reality, even of (...) its most unfathomable layers and seemingly bizarre phenomena. Focusing on the case of Émile Boirac’s research on what he termed ‘cryptopsychism’, notably in his book Our Hidden Forces, this article aims to show how Kantian notions and models of consciousness belonging to the canon of French spiritualist philosophical psychology were taken up by scientists such as Pierre Janet and ended up being assimilated and discussed in the more obscure and precarious realm of scientific inquiry into metapsychical phenomena. Far from being a mere historical curiosity, this quest for a scientific account of the latent and subconscious life of the mind sheds light on the intricate relationship between philosophy and the human sciences between the 19th and 20th centuries.

While there were several psychical research journals during the nineteenth century many interesting discussions about psychic phenomena took place as well in a variety of intellectual reviews and scholarly and scientific journals of various disciplines. One such example was the French journal Revue Philosophique de la France et de l’Étranger founded in 1876 by Théodule Ribot. Reflecting the various interests of psychologists during the nineteenth century many topics were discussed in the Revue, among them hypnotic phenomena, as well as mental (...) suggestion and mediumship. The journal provided an important forum for French discussions in psychology and in the social sciences in general that helped the development of those disciplines. The same may be said about psychic phenomena, which were discussed in the pages of the Revue by authors such as Émile Boirac, Victor Egger, Théodore Flournoy, Jules Héricourt, Pierre Janet, Léon Marillier, Julian Ochorowicz, Charles Richet, and Albert Ruault. We present summaries of some of these writings which we hope will bring some of this material to the attention of non-French readers. (shrink)
