Exorcism: a psychiatric viewpoint.

Doctors, for several reasons, should be concerned with exorcism is the view of Professor Trethowan, who in this paper, looks at the main features of exorcism as practised in the middle ages and now appearing in the modern world, as was seen in the recent Ossett case in Britain. He examines in some detail the nature of supposed demoniacal possession and describes its symptoms and signs. He also touches on the social, as opposed to the religious, background in which demoniacal possession flourished (not lacking in the world today), so leading to an examination of the psychodynamic aspects of demoniacal possession and the question of absolute evil. Finally he compares the techniques of exorcism and of modern psychiatric practice.
