Who is Herbert ?

This man was an exceptionally difficult case. When Erickson meets him he has been hospitalized and is being force fed through tubes. Herbert denies that he even has a stomach. Erickson works with him, and in standard form, assures Herbert, that is going to allow Herbert to re-evaluate conditions for himself. Over time, he gets Herbert to perform work, to exercise, and exposes him to high quality food so Herbert resumes eating and will admit that he has a stomach.
