Leo Marx opens The Machine in the Garden, his classic 1964 study of technology’s influence on American culture, with a recounting of Hawthorne’s morning in Sleepy Hollow. The writer’s real subject, Marx argues, is “the landscape of the psyche” and in particular “the contrast between two conditions of consciousness.” The quiet clearing in the woods provides the solitary thinker with “a singular insulation from disturbance,” a protected space for reflection. The clamorous arrival of the train, with its load of “busy men,” brings “the psychic dissonance associated with the onset of industrialism.” The contemplative mind is overwhelmed by the noisy world’s mechanical busyness.
