Théodore Flournoy (15 August 1854 – 5 November 1920) was a professor of psychology at the University of Geneva and author of books on spiritism and psychic phenomena. He is most known for his study of the medium Helen Smith (or Hélène Smith - a pseudonym for Catherine Muller) who relayed information about past lives through a trance state, entitled From India To The Planet Mars (1899). He proposed this information as 'romances of the subliminal imagination,' and a product of the unconscious mind (Stevens 1994). Flournoy was a contemporary of Freud, and his work influenced C. G. Jung's study of another medium - his cousin Héléne Preiswerk - which was turned into Jung's doctoral dissertation in 1902. Flournoy was also one of the few scholars of his time to embrace William James' view of the prime reality of non-dual consciousness (which he dubbed "sciousness") as expressed in his essay, Radical Empiricism.Flournoy’s most famous work, From India to the Planet Mars, discusses a wide range of topics, including Alien Communications, Mediumship, Automatic Writing, Reincarnation, Séances, Psychic Phenomena, Psychological Studies, and Science.
