The past ages of man have all been carefully labeled by anthropologists (人类学家). Descriptions like "Palaeolithic (旧石器时代的) Man". "Neolithic (新石器时代的) Man",etc. neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label "Legless Man". Histories of the time will go something like this:"in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts in all large buildings to prevent people from walking. And the surprising thing is that they didn't use their legs even when they went on holiday."

The future history books might also record that we were deprived (剥夺) of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird's-eye view of the world. When you travel by car or train, an unclear picture of the countryside constantly smears the windows. Car drivers, especially, are mixed with the urge to go on and on: they never want to stop. The typical twentieth-century traveler is the man who always says "I've been there." You mention the remotest, and someone is bound to say "I've been there"-meaning, "I drove through it at100 miles an hour on the way to somewhere else."

When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical tiredness. He knows that sound, satisfying sleep will be his: the just reward of all true travelers.
