Allan Kardec - Spirit Interest

Spirit Interest

He was already in his early 50s when he became interested in the wildly popular phenomenon of spirit-tapping. At the time, strange phenomena attributed to the action of spirits were reported in many different places, most notably in the U.S. and France, attracting the attention of high society. The first such phenomena were at best frivolous and entertaining, featuring objects that moved or "tapped" under what was said to be spirit control. In some cases, this was alleged to be a type of communication: the supposed spirits answered questions by controlling the movements of objects so as to pick out letters to form words, or simply indicate "yes" or "no."

At the time, Franz Mesmer's theory of animal magnetism was popular in the upper reaches of society. When confronted with the phenomena described, some researchers, including Rivail, pointed out that animal magnetism might explain them. Rivail, however, after personally seeing a demonstration, quickly dismissed the animal-magnetism hypothesis as being insufficient to completely explain all the facts observed (see Chapters VIII and XIV in The Book on Mediums). Rivail was determined to understand exactly what was causing the physical effects popularly attributed to spirits.
