You can read about the so called l=a=n=g=u=a=g=e poet's rejection of closure here (it's short). Is she saying that an open reading, which is what the text is about, theorizes on, does not privilege different goals in reading, e.g. working out whodunit?
Hejinian is explicitly saying that there are many readings of an open text, so I just wondered if each different method, way, of reading a text is equally viable.
The “open text” often emphasizes or foregrounds process, either the process of the original composition or of subsequent compositions by readers
