"You got to walk that lonesome high way / You got to walk it by yourself." Blurred edges, I like that. I've only read a little Whitehead, but coming round to this notion of process has really freed me up. You're right about the higher ontological status we tend to assign to nouns. Down with nouns! And yet, it is standard advice in beginning poetry classes to tell students to work with concrete nouns & active verbs that evoke sensual reality. And you know what? The advice leads to better poems. Or is that just my aesthetic bias, ultimately a social construction of literary Modernism?
