Even in these mercifully emancipated decades, many people still seem quite seriously alarmed at the prospect of sleeping away from officially consecrated campsites, with no more equipment than they can carry on their backs. When pressed, they babble about snakes or bears or even, by God, bandits. But the real barrier, I'm sure, is the unknown.

Life should be an unfinished business.

There there is nothing like a wilderness journey for rekindling the fires of life. Simplicity is part of it. Cutting the cackle. Transportation reduced to leg - or arm - power, eating irons to one spoon. Such simplicity, together with sweat and silence, amplify the rhythms of any long journey, especially through unknown, untattered territory. And in the end such a journey can restore an understanding of how insignificant you are -- and thereby set you free.

Every walk of life falls under the Testicular Imperative: Either you have the world by them, or it has you.

The best dress for walking is nakedness. But our sad though fascinating world rarely offers the right and necessary combinations of weather and privacy, and even when it does the Utopia never seems to last very long.

It is always there, of course, when you come back from the green world. You have been living by sunrise and sunset, by wind and rain, surrounded by the ebb and flow of lives that respond only to such simple, rhythmic elements. But now the tone and tempo of the days switch. Instead of harmony, jangle.

By walking naked you gain far more than coolness. You feel an unexpected sense of freedom from restraint. An uplifting and almost delirious sense of simplicity. In this new simplicity you soon find that you have become, in a new and surer sense, and integral part of the simple, complex world you are walking through. And then you are really walking.
