long, continuing process

In 1956, I had begun dating each of my poems by year. I did this because I was finished with the idea of a poem as a single, encapsulated event, a work of art complete in itself; and I knew my life was changing, my work was changing, and I needed to indicate to readers my sense of being engaged in a long, continuing process. It seems to me now that this was an oblique political statement—a rejection of the dominant critical idea that the poem’s text should be read as separate from the poet’s everyday life in the world. It was a declaration that placed poetry in a historical continuity, not above or outside history.
