"Demonism, Verified and Analyzed" is more than just a standard work covering demons and demonic possession. Past the demonology of prior eras, it wraps spiritual influence up with the psychic and mental, and proposes not just that prayer is an aid to the same, but why, according to the author, it is so. As a strictly protestant work, it delves heavily into specific anecdotes of possession and sickness in China, India, and other areas while proposing a literal Satan, literal host of demons, and literal harm from demonism.
