In Of the Natural World we glean Bronk’s descent from the lineage of Thoreau and Whitman. Nature is tantamount to God. That the narrator wants to “practice the world’s song” recalls the more scientific Thoreau while his impatience and desire to achieve union with nature suggest the more sensual Whitman and prompted me to compose a final verse of vocalise for the singer/narrator.
