In Vogue’s 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s “Ulysses”: “Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.” He drew a charming one himself. Several decades later, a Boston College English professor named Joseph Nugent and his colleagues put together an annotated Google map that shadows Stephen Dedalus and Leopold Bloom step by step. The Virginia Woolf Society of Great Britain, as well as students at the Georgia Institute of Technology, havesimilarly reconstructed the paths of the London amblers in “Mrs. Dalloway.”
Such maps clarify how much these novels depend on a curious link between mind and feet. Joyce and Woolf were writers who transformed the quicksilver of consciousness into paper and ink. To accomplish this, they sent characters on walks about town. As Mrs. Dalloway walks, she does not merely perceive the city around her. Rather, she dips in and out of her past, remolding London into a highly textured mental landscape, “making it up, building it round one, tumbling it, creating it every moment afresh.”
Since at least the time of peripatetic Greek philosophers, many other writers have discovered a deep, intuitive connection between walking, thinking, and writing. (In fact, Adam Gopnik wrote about walking in The New Yorker just two weeks ago.) “How vain it is to sit down to write when you have not stood up to live!” Henry David Thoreau penned in his journal. “Methinks that the moment my legs begin to move, my thoughts begin to flow.” Thomas DeQuincey has calculated that William Wordsworth—whose poetry is filled with tramps up mountains, through forests, and along public roads—walked as many as a hundred and eighty thousand miles in his lifetime, which comes to an average of six and a half miles a day starting from age five.
What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs—including the brain. Many experiments have shown that after or during exercise, even very mild exertion, people perform better on tests of memory and attention. Walking on a regular basis also promotes new connections between brain cells, staves off the usual withering of brain tissue that comes with age, increases the volume of the hippocampus (a brain region crucial for memory), and elevates levels of molecules that both stimulate the growth of new neurons and transmit messages between them.
