“Although modern man rarely questions the value of exploration, the explorer pursues a course of activity that seems, logically, at variance with man’s basic strivings for the good life, the best obtainable in food, shelter, and all those other physical, mental and spiritual comforts that characterize civilized life. The explorer deliberately turns his back on civilization and its pleasures simply to go and see unknown lands. Yet the explorer is always a civilized man; exploration itself is an advanced intellectual concept. The primitive or half-civilized man may move into new lands for food, protection or trade, but he is always driven there by necessity or greed and rarely troubles to record what he has seen. The true explorer goes only to see and to tell others what he has seen. It seems incredible, considering the hardships and dangers, that men would willingly do this. I speak of men rather than women because the spirit of adventure that leads to exploration is primarily a masculine trait; women, being more sensible and their curiosity being confined to more personal and realistic matters nearer home, are less afflicted by the desire to see what lies beyond the seas and mountain ranges. But this spirit lurks in all men, I would guess, to a greater or lesser degree. In some it is weak and easily satisfied by novels or television; in others it is a ruling passion that thrusts them to the remote corners of the globe.”
