“Objects are concealed from our view not so much because they are out of the course of our visual ray . . . as because there is no intention of the mind and eye toward them.”
—Henry David Thoreau, quoted by Victor Carl Friesen in A Tonic of Wildness: Sensuousness in Henry David Thoreau; from Empire of the Senses: The Sensual Culture Reader, edited by David Howes, 2005.
