I think about this split quite often. As someone with two degrees largely focused on literature, and seeking one focused on rhetoric, I find myself lost in the (messy and often blurred) boundaries between the two fields. The later assertion from Mill, "For poetry, utterance is the end, not, as in rhetoric, the means to an end" (996) seems to hold true even today. Literature is rarely seen as social action, let alone socially engaged. I wonder how damaging (or not) this is as we attempt to think about "our disciplinary identity crisis less as a crisis of identity and more as an opening of alterity" (Muckelbauer).
This is probably why I am so intrigued by Muckelbauer's argument that "we might even conceive of rhetoric as, in a certain way, disengaging from the entire problematic of 'fields,' disconnecting from both 'interdisciplinary studies' and work in the 'rhetoric of x' genre (indicating, perhaps, an ontological rhetoric)."
But what does this look like? How does this happen? The end of this intro seem to give some hope -- "Literary theorists, too, began to acknowledge...the wider scope afforded by a rhetorical approach to discourse" (998, emphasis mine). But how often is literature viewed as discourse? And is this a reciprocal engagement?
