Mary Douglas viewed the human body as a symbol of society, my example may be taking that idea to the extreme as it is the discussion of human body being used as symbols. She presented the idea of matter out of place. Some item that is outside of the context to which we are accustomed is unsettling demarking a boundary and highlighting differing categories in which symbolic ideas are acceptable.
The article I link to above is a visual representation of both of these ideas. Females on the covers of romance novels are often depicted in impossible positions and subordinate to any males in the images. To a lesser extent these depictions are exaggerated and impossible for males shown as well.
What is the author – and to be more fair the publisher – saying about male and females and about their interactions with these covers? It is an image we can support, is it a reality within our culture or a reinforcement of division and the possibilities that with enough work we could all attain this ideal type? What happens when we fail? When the man or woman we choose a the romantic lead in our lives fails to live up to these iconic standards? More disillusionment and a lack of social cohesion, rampant neuroses, disharmony both mentally and in our relationships, and divorce.
The book sells though. Often the descriptions of the men and women in the story have no bearing on the cover at all.
