If you need a doctor you don’t want to go to a poet unless she or he has a medical degree. And yet it amazes me how many creative writers believe that poetry heals people. My contention has always been that poetry won’t hurt you overmuch and it can turn you from depression toward fascinations. But it won’t cure depression and it won’t make you whole. Moreover, some of the most vicious and dishonest academic creative writers are the loudest purveyors of the poetry will heal you movement. This is MFA as snake oil. AWP as therapeutic massage.
The flip side of this is the Robert Bly school of thought: you must live alone and suffer like St. John of the Cross in order to be an artist. This is also bullshit. Eschewing happiness won’t make you creative. The very idea is like putting on a scourge, stuffing stones in your shoes. Bly dined out on this idea for years. Picture the average poetry audience: half believing poetry would cure their hangnails; the other half believing they needed more hangnails.
The poetry will heal you school thinks that the body is a thing to be overcome. It views the head as a lifeboat from disablement. Poetry is supposed to fix you up, and damn, here comes one of those crippled poets to mess it all up!
