Spiritualism and Necromancy: Now Available!
This is a rather nice work that primarily relates to demons and demonology, from the particular perspective of the fire and brimstone Methodist path that, in the 19th century, was at war with spiritualism. In the foreword, I had to make it clear to the reader that as an occultist I reject some of the anti-spiritualist materials here, although the first sections primarily deal with fraud mediums and is accurate.
According to this work, many mediums and self professed clairvoyants are indeed contacting spirits- but those spirits are evil demons from Hell instead of the souls of the dead or elemental forces. The religious arguments made here simultaneously make it clear that some spiritualists are not evil but rather misled, even if they are still bound for Hell.
