Daniel Taylor in a review of David Farley’s Modernist Travel Writing, writes: "The essence of travel is putting yourself in a different place—and coming back changed. If you go somewhere and don't come back, you haven't traveled, you have simply moved. If you go and come back but are not changed, you haven't traveled, you have simply been a tourist. There is an element of pilgrimage (physical travel for a spiritual purpose) in all genuine travel, and the urge in human beings to do so is timeless.

"On the other hand, we have been reminded, by people as diverse as the medieval Cistercians (who discouraged pilgrimage) and Henry Thoreau (who said explore your inner spaces before exploring outer ones), that spiritual and intellectual quests are also a form of travel. The greatest discoveries, they argue, are not over the horizon, but within the soul and mind.

But why not both? Why not put both body and mind in motion and allow them to feed each other?"
