Margins: the poetic text and its theoretical gesturing

Say poem and I see margins emerging. Question. How marginal is poetry? To answer my question I must shift to the margins of poetics and you must be prepared to occupy the margins of poetry. Why? Because the discourse produced in that kind of 'in-between' space stakes out for itself and shows how poetry is a language mode that challenges speech and thought frames as it displaces them towards, or within, various margins. And why? Because poetry puts its finger on the disjunction between speech and writing. After all, Rilke says somewhere that poetry is the capacity to 'remain in the open', the ability to take risks. And so, any attempt to define a marginal space for poetry implies some desire to leave poetic texts open, mobile, and not to lock them forever in neat structures produced by criticism - interpretations that would exhaust them.
