"... a secular equivalent for possession as an explanation of how a good person can behave badly..."R. Room

This paper considers the relation to the concept of elements in current professional definitions of addiction (as dependence). Addiction concepts have become a commonplace in storytelling, offering a secular equivalent for possession as an explanation of how a good person can behave badly, and as an inner demon over which a hero can triumph.
