The imperialist and patriarchical hierarchy between author and reader.

Rich Smith writes,

Conceptual poetry, like conceptual art, privileges a reader’s thoughts about the text over the author’s rhetorical devices within the text. . .  These writers imagine the text not as a thing that should absorb you, but as a reflecting pool into which you can look and see and think whatever you want to see. Conceptualists claim this dissolves the imperialist and patriarchical hierarchy implied by the traditional relationship between author and reader.
