Reference, like the body itself ...
In the introduction to The L=A=N=G=U=A=G=E Book Charles Bernstein and Bruce Andrews wrote that:
[C]onfusion about the nature of this exploration flourishes. For instance, the idea that writing should (or could) be stripped of reference is as bothersome and confusing as the assumption that the primary function of words is to refer, one-on-one, to an already constructed world of “things.” Rather, reference, like the body itself [and there, again, is the body, the “plan”], is one of the horizons of language … It is the multiple powers and scope of reference (denotative, connotative, associational), not writers’ refusal or fear of it, that threads these essays together. It is a renewed engagement that comes from the recognition that the (various) measuring and questioning and composition of our references is the practice of our craft.
