Morals and Practices of Demons or Visiting Spirits

Originally published in the 19th century, this powerful treatise by Henri Roger Gougenot des Mousseaux (1805–1876) remains one of the most striking examinations of the demonic and spiritualist phenomena that gripped Europe during the rise of séances, occultism, and modern spirit communication.

Morals and Practices of Demons or Visiting Spirits is more than a catalog of ghostly visitations—it is a fierce argument that the entities summoned by mediums are not benevolent guides, but deceptive and dangerous spirits whose origins lie in the infernal. With a blend of historical accounts, theological warnings, and documented manifestations, Des Mousseaux exposes the moral corruption, strange phenomena, and perilous influence attributed to these spirits.

Feared and respected in his own time, Des Mousseaux influenced not only the Catholic Church’s stance on Spiritualism but also the wider European debate on the unseen world. Today, his work endures as a classic of demonology and occult criticism, offering a rare window into the clash between faith, superstition, and the burgeoning spiritualist movement.
