Classics and Complexity in Walden’s “Spring” M. D. USHER In 1843, two years before Henry Thoreau built his cabin at Walden Pond, the Fitchburg Railroad laid down tracks through the woods near the Pond for its line connecting Boston to Fitchburg. The original Fitchburg Line, at 54 miles long, was, until 2010, the longest run in the present -day MBTA Commuter Rail system. And it is one of the oldest railways in New England. By 1900, fortunes swelled and the Fitchburg’s Hoosac Tunnel Line took passengers and goods westward toward Chicago. The Lake Champlain Route connected Boston to points north like Burlington, Vermont .

The Railroad was literally a fixture in Thoreau’s landscape . Its tracks pass remarkably close to Walden Pond (Figure 2), and the Fitchburg Line—both its reality and the specter of it—is practically a character in his writing: “I usually go to the village along its causeway, and am, as it were, related to society by this link,” Thoreau writes in “Sounds,” a chapter of Walden that contains what must be one of the most picturesque odes (or laments) to rail travel and commerce in all of American literature: The engine’s whistle, Thoreau complains, pierces the still silence of his idyllic retreat like a screaming hawk circling a farmer’s field, its billows of steam an ominous harbinger of “this travelling demi-god, this cloud-compeller.”1 Thoreau’s frequent, customary walks into Concord along the railroad tracks took him through a heavily excavated stretch of the line known as the Deep Cut, to which he returned again and again each year in early spring, even after leaving the cabin, to observe and to record his observations. The leaf-shaped sand flows and trickling surface erosion caused by melting frost in the banks of the Deep Cut are elaborately described in Thoreau’s chapter in Walden entitled “Spring,” what Laurence Buell calls the “high point of Thoreau’s epic.”2 And yet, in spite of the universal acclaim of this passage as a literary tour de force, it has not received the full attention it deserves. What warrants fresh consideration first and foremost is “Spring”’s deep-rootedness in classical sources. Many classical influences, allusions, and a good deal of etymological word play have gone so far unnoticed . The chapter is also important because it describes, by intimation, what contemporary scientists now call emergence . Emergent phenomena are properties or behaviors that arise in systems as a result of complex, dynamic interactions amongst constituent parts, including changes to a system brought about by human interventions3—not only, e.g., climate change and wildfires, but also traffic patterns and terrorist networks; kidney function in the body; the rings of Saturn. As he tries to capture the essence of the 114 classics and complexity in WALDEN’s “spring” Deep Cut and interpret its significance, Thoreau adumbrates this concept, but also grapples ingeniously with broader issues of perennial concern—the relationship of Nature to Culture, for example, of Wilderness to Civilization , of Science to the Humanities—making “Spring” not only a probing work of eco-criticism and environmental philosophy, but of scientific reflection and poetic experiment as well. In short, Thoreau’s “Spring” is that rare work of classical reception that transmits both literary and scientific insight. Perhaps at this point, in lieu of accolades, it is best to let Thoreau start speaking for himself. What I offer in the following pages is a commentary on the Deep Cut passage from “Spring.” Classical references and aspects of systems theory will be explained and contextualized as they emerge, as it were, from Thoreau’s text. The whole chapter corresponds to pages 289–308 in Cramer’s edition of Walden—26 paragraphs all told, of which only the relevant ones are printed and annotated here.
