　　Of all the characteristics that man has used to distinguish himself from“lower”animals，the desire to explore the unknown may be the most enduring.As the Norwegian polar explorer and oceanographer Fridtjof Nansen observed，“Man wants to know，and when he ceases to do so，he is no longer man.”

　　The annual migrations of wildfowl and many other animals certainly cannot be regarded as a form of exploration，because such movements are actually only shifts from one habitat to another for the purpose of avoiding seasonal climatic variations.4) Likewise，the gradual expansion by certain animals into new ranges is not exploratory but rather merely a shift to a 1ess crowded or more favourable environmental setting.To be sure，mankind also has been involved in movements of this sort when subjected to population and other pressures.Then，too，economic and military considerations have frequently been major driving factors in human expansion into new realms.5)Nonetheless，in numerous instances，man‘s attempts at exploration have been marked by imaginative leaps across hostile stretches，sometimes at great risks， to reach something undefined simply for its own sake.

　　Much of the history of exploration—certainly of modern geographical exploration—has been European.6) Such has been the case not because Europeans possessed superior curiosity or some other internal force but because whatever events channeled their societies toward an advanced level of technology allowed them to expend more energy on exploration.The rapid growth and consolidation of their kingdoms provided them with an opportunity to exploit new discoveries fully.By contrast，the great Asian kingdoms，though no less capable，turned inward and erected walls between themselves and the“barbarians”of the outside world.

　　The 20th century has witnessed the last stages of exploration of the Earth‘s surface and the initial attempts to explore the deep sea and space.Scientific attention today is primarily directed toward these new frontiers.In addition to this emphasis on undersea and space exploration，efforts are also being made to investigate the interior of the Earth，knowledge of which still remains relatively limited.
