“The conclusion drawn by … most of our élites … is that the population constitutes a deep and dangerous well of ignorance and irrationality; if our civilization is in crisis the fault must lie with the populace which is not rising to the inescapable challenges. And yet civilizations do not collapse because the citizenry are corrupt or lazy or anti-intellectual. These people do not have the power and influence to either lead or destroy. Civilizations collapse when those who have power fail to do their jobs.”

"The Wisdom of Wilderness" in LIFE (22 December 1967)
Context: The wild world is the human world. Having evolved in it for millions of centuries, we are not far removed by a cloth of civilization. It is packed into our genes. In fact, the more power-driven, complex and delicate our civilization becomes, the more likelihood arises that a collapse will force us back to wildness. There is in wildness a natural wisdom that shapes all Earth's experiments with life. Can we tap this wisdom without experiencing the agony of reverting to wildness? Can we combine it with intellectual developments of which we feel so proud, use it to redirect our modern trends before they lead to a worse breakdown than past civilizations have experienced? I believe we can, and that to do so we must learn from the primitive.
