Bodin’s critics became more serious and dangerous with regard to his On the Demon-mania of Witches that was published in 1581 (Démonomanie). In his letter of dedication (December 20, 1579) to Christophle de Thou, the first president of the Parlement of Paris, Bodin explains why he write the work and the meaning of its title. First, he hoped to denounce the mania, the spiritual errors, and distraction, as well as the “fury” that sorcerers possess as they “chase after the devil.” He wrote this treaty with two purposes in mind: on the one hand, “to use it as a warning to all who will see him [the devil],” and on the other hand, “to alert readers that there is no crime that could be more atrocious or deserve more serious punishment.” Bodin wished to speak out against those who “try by all means to rescue the sorcerers through printed books.” He reminded all that “Satan has men in his grasp who write, publish, and speak claiming that nothing that is said about sorcerers is true.” It was essential to provide the tools to magistrates and judges, who were confronted by the accused sorcerers, in order to face this formidable problem. The work was bold and perilous for its author. Many wondered if Bodin, so curious about this topic, such an expert, so convinced of the devil’s existence, may not himself have been involved with witchcraft. These suspicions alarmed the authorities, and on June 3, 1587, the general prosecutor to the Parlement of Paris ordered the general lieutenant of the baillage of Laon to proceed with a search of Bodin’s home, on suspicion of witchcraft. This inspection brought no results due to the intervention of eight prominent citizens and two priests who registered their support of Bodin.
