Demonology

Demonology is a field that one might say exists in an academic "twilight zone" where Science, Psychology, Religion, and Parapsychology intersect. Its practitioners, mostly members of the clergy (across several faiths), purport to study demons and other evil spirits and their effects on the world. It is a field that is taken very seriously by some religious denominations but generally discounted as nonsense by a large segment of the population.
