如果生活的要义在于追求幸福，那么，除却旅行，很少有别的行为能呈现这一追求过程中的热情和矛盾。不论是多么的不明晰，旅行仍能表达出紧张工作和辛苦谋生之外的另一种生活意义。尽管如此，旅行还是很少迫使人去考虑一些超越实际、需要深层思索的哲学层面的问题。我们经常得到应该到何处旅行的劝告，但很少有人告诉我们为什么要到那个地方，又如何到达那个地方，尽管旅行的艺术会涉及一些既不简单，也非细小的问题，而且，对旅行的艺术的研究可能在一定意义上（也许是微不足道的）帮助人们理解希腊哲人所谓的“由理性支配的积极生活所带来的幸福”（eudaimonia）或人类昌盛。

If our lives are dominated by a search for happiness, then perhaps few activities reveal as much about the dynamics of this questin all its ardour and paradoxesthan our travels. They express, however inarticulately, an understanding of what life might be about, outside the constraints of work and the struggle for survival. Yet rarely are they considered to present philosophical problemsthat is, issues requiring thought beyond the practical. We are inundated with advice on where to travel to; we hear little of why and how we should go-though the art of travel seems naturally to sustain a number of questions neither so simple nor so trivial and whose study might in modest ways contribute to an understanding of what the Greek philosophers beautifully termed eudaimonia or human flourishing.
