Abstract

The adverse report of the Academy of Sciences, published in 1784, failed to put an end to the proselytism of Mesmer's early followers, nor did it scale down their ambitions to gain scientific recognition. The allure of mystery, the taste for wonders and the call of the unknown prevailed, and throughout that century numerous clashes occurred between the scientific establishment and those demanding its recognition. Their demand was founded not so much on a theoretical construct as on people's personal experiences as actors or witnesses, which were perceived to be true simply because they were nearly always profoundly disturbing. The fact is that, despite the observations of scientists such as Faraday, anyone could put questions to an ecstatic in a state of trance, have a medium summon the dead, or communicate with the “other world” by table-turning. Insofar as it rejected the validity of the most commonly accepted “research programmes”, the challenge to the institutions that were the guarantors of received knowledge was a major one.
