Like the death of Emerson's wife Ellen in 1831 or of his brother Charles five years later, the death of John Thoreau in 1842 was critical in “terminat[ing] an epoch of infancy or of youth which was waiting to be closed” (CW II, 73), as Emerson generalized from his own experience of loss. Among other things, A Week is Thoreau's elegy for John, who, “freed from the limitations of human life,” as Linck Johnson observes, “had begun to assume to Thoreau the status of a pure idea.” A Week is also, however, Thoreau's valediction to his own outgrown self. The “wholly new life, which no man has lived” (Wk 377), and which Thoreau returns to Concord to attempt, will be a life not only without his brother but without many of the attitudes and postures adopted in his first book.
