"Not so many years ago there there was no simpler or more intelligible notion than that of going on a journey. Travel--movement through space--provided the universal metaphor for change.... One of the subtle confusions--perhaps one of the secret terrors--of modern life is that we have lost this refuge. No longer do we move through space as we once did."
"There is a wonderful, but neglected precision in these words. The old English noun "travel" (in the sense of a journey) was originally the same word as "travail" (meaning "trouble," "work," or "torment").... Significantly, too, the word "tour" in "tourist" was derived by back-formation from the Latin "tornus," which in turn came from the Greek word for a tool describing a circle. The traveler, then was working at something; the tourist was a pleasure-seeker. The traveler was active; he went strenuously in search of people, of adventure, of experience. The tourist is passive; he expects interesting things to happen to him."
