“A handful of types of elementary particles, which vibrate and fluctuate constantly between existence and non-existence and swarm in space even when it seems that there is nothing there, combine together to infinity like the letters of a cosmic alphabet to tell the immense history of galaxies, of the innumerable stars, of sunlight, of mountains, woods and fields of grain, of the smiling faces of the young at parties, and of the night sky studded with stars.”

Context: Walking has been one of the constellations in the starry sky of human culture, a constellation whose three stars are the body, the imagination, and the wide-open world, and though all three exist independently, it is the lines drawn between them—drawn by the act of walking for cultural purposes—that makes them a constellation. Constellations are not natural phenomena but cultural impositions; the lines drawn between stars are like paths worn by the imagination of those who have gone before. This constellation called walking has a history, the history trod out by all those poets and philosophers and insurrectionaries, by jaywalkers, streetwalkers, pilgrims, tourists, hikers, mountaineers, but whether it has a future depends on whether those connecting paths are traveled still.

“Over all the sky—the sky! far, far out of reach, studded with the eternal stars.”
