In his essay for The Chronicle of Higher Education, Robert Manning, professor in the Rubenstein School of Natural Resources, explores the "biomechanical marvel" of bipedalism along with the powerful historical connection between walking and philosophy, scholarship, literature, human rights protests and spirituality, from Aristotle to Martin Luther King. Of John Muir, Manning says, "His walks offered him deep insights into our relationship with the natural world, writing, "'I only went out for a walk, and finally concluded to stay out until sundown, for, going out, I found, was really going in.'" The piece is excerpted from his book, Walking Distance: Extraordinary Hikes for Ordinary People. Read the story at Chronicle.com (subscription required)... or contact University Communications.
