I am not sorry for having wrought in common, crude material so much; that is the right American stuff; and perhaps hereafter, when my din is done, if anyone is curious to know what that noise was, it will be found to have proceeded from a small insect which was scraping about on the surface of our life and trying to get into its meaning for the sake of the other insects larger or smaller. That is, such has been my unconscious work; consciously, I was always, as I still am, trying to fashion a piece of literature out of the life next at hand.

Letter to Charles Eliot Norton (April 26, 1903).
