The following passage is excerpted from “The Cure Within: A History of Mind-Body Medicine” by Anne Harrington—a recent addition to my recommended reading list.
The End of Medical Exorcism in Europe
Appreciating the interweaving religious, philosophical and political stakes [in 18th century medicine] is important, because it can help us make sense of an episode whose significance we might otherwise misinterpret: the showdown between the German exorcist Father Johann Joseph Gassner and the Viennese physician Anton Mesmer.
Gassner was an exorcist whose ability to cast out devils was legendary. People came from all over to be healed, and in dramatic public performances—witnessed by crowds from all sectors of society—Gassner would oblige. Official records were made; competent witnesses testified to the extraordinary happenings. All agreed on the basic facts. On being presented with a supplicant, Gassner would typically wave a crucifix over his or her body and demand in Latin that, if the disease he was seeing had a “preternatural” source, this fact must be made manifest. The patient would then typically collapse into convulsions, and Gassner would proceed to exorcise the offending spirit.
Sometimes he added flourishes to this basic routine: in one dramatic instance, for example, he ordered the demon inside a woman to increase the poor woman’s heartbeat and then to slow it down.
