A term coined by psychologist Max Dessoir (18671947) in
Germany in 1889 and picked up by psychical researcher Emile
Boirac (18511917) and used to refer to all phenomena produced
in living beings or as a result of their action, which do
not seem capable of being entirely explained by already known
natural laws and forces. According to Boirac, the term psychical
is not satisfactory because it is synonymous with mental.
The prefix para denotes that it relates to exceptional,
abnormal, paradoxical phenomena. The term found some acceptance
in Germany during the establishment of psychical research.
