Spiritualism is the metaphysical school of thought opposing physicalism and also is the category of all spiritual beliefs/views from ancient to modern. In the Late Modern Age, Spiritualism became most known as a social religious movement according to which the laws of nature and of God include "the continuity of consciousness after the transition of death" and "the possibility of communication between those living on Earth and those who have made the transition". The afterlife, or the "spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to a third belief: that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God. Some spiritualists will speak of a concept which they refer to as "spirit guides"—specific spirits, often contacted, who are relied upon for spiritual guidance. Emanuel Swedenborg has some claim to be the father of Spiritualism. Spiritism, a branch of spiritualism developed by Allan Kardec and today practiced mostly in Continental Europe and Latin America, especially in Brazil, emphasizes reincarnation.
A séance or seance is an attempt to communicate with spirits. The word séance comes from the French word for "session", from the Old French seoir, "to sit". In French, the word's meaning is quite general: one may, for example, speak of "une séance de cinéma". In English, however, the word came to be used specifically for a meeting of people who are gathered to receive messages from ghosts or to listen to a spirit medium discourse with or relay messages from spirits. In modern English usage, participants need not be seated while engaged in a séance.
Charles Robert Richet was a French physiologist at the Collège de France known for his pioneering work in immunology. In 1913, he won the Nobel Prize in Physiology or Medicine "in recognition of his work on anaphylaxis". Richet devoted many years to the study of paranormal and spiritualist phenomena, coining the term "ectoplasm". He also believed in the inferiority of Black people, was a proponent of eugenics and presided over the French Eugenics Society towards the end of his life. The Richet line of professorships of medical science would continue through his son Charles and his grandson Gabriel. Gabriel Richet was one of the great pioneers of European nephrology.
