ABSTRACT
The action to control the illness can proceed by reference to explanation at two levels, by reference to what Evans-Pritchard called dual causality. Those who bring it forward are not primarily concerned with mutual consistency between different chains of reasoning but with finding a reasoned basis for treatment. In general, it is said that spirits, destructive magic and sorcery all cause death. The idea of a spirit striking with madness though not possessing or entering occurs in the ritual work of hunting magic. The interplay of their ideas of contagion and infection or the related ones of the binding or localization of spirits to a place or a person, and their release: the part played in diagnosis by strange signs, the revelations of dreams or spirit possession: a host of things to be considered if the cause must be brought to light.
