Jean-Jacques Rousseau defined civilization as when people build fences. A very perceptive observation. And it’s true—all civilization is the product of a fenced-in lack of freedom. The Australian Aborigines are the exception, though. They managed to maintain a fenceless civilization until the seventeenth century. They’re dyed-in-the-wool free. They go where they want, when they want, doing what they want. Their lives are a literal journey. Walkabout is a perfect metaphor for their lives. When the English came and built fences to pen in their cattle, the Aborigines couldn’t fathom it. And, ignorant to the end of the principle at work, they were classified as dangerous and antisocial and were driven away, to the outback. So I want you to be careful. The people who build high, strong fences are the ones who survive the best. You deny that reality only at the risk of being driven into the wilderness yourself.
