Walking as a method of gaining knowledge is not new. The Peripatetic School meandered under the trees to learn Philosophy under the tutelage of Socrates and Aristotle; Jean Jacques Rousseau wrote about walking in "Confessions" and "Reveries of a Solitary Walker"; Henry David Thoreau wrote the essay "Walking" in 1862; and the avant-garde Situationists' idea of dérive challenged the rise of consumerist spectacle. These examples show the long history of walking as a method of generating ideas, art, and critique. HPU is an ongoing collaboration with like-minded individuals to explore, experiment, and engage with such historical ideas around perambulation, as well as with current concepts and artistic practices.
