It is restful to leave one's home; not because traveling does not entail varied and difficult daily actions, but because it removes our responsibilities. Except in the case of official persons, the traveler now lives for himself alone, and is no longer accountable to a community or a family clan. A foreign country is merely a spectacle; in it we no longer have the continual awareness of responsibility. All of us, from time to time, need a plunge into freedom and novelty, after which routine and discipline will seem delightful by contrast. Periods of rest, however, must be brief, but it is amazing to discover how a few days of travel can restore our mental freshness.
