Quoted from Alice Notley over in the Hotel:

"The form, it must be acknowledged, is still wonderfully serviceable, a collaged entity which seems able to manage any juxtaposition of material, sound, and tone, and which is welcoming to most kinds of novelty of line and layout. All of that is also the form’s weakness: it tempts endless heterogeneity and in its fragmentation makes little room for whatever unity there is in actual existence. I myself think there is quite a bit of unity in actual existence, and also that an epic by definition is a presentation of unity to whatever culture the epic serves."

Touche.
