Here you will find discussions on demons, possession,
how to determine the difference between possession and
mental illness, and exorcism.  You will also find
accounts of exorcisms and a history of demon-beliefs
and the science of demonolgy.  Although I have tried to preserve a religion-neutral appoach to the subject, any
attempt to research demonology is, by its very nature, going to be "flavored" by religious matters, since the
history of demonology also tends to be the history of
religious beliefs.
