The Native Americans, whose wisdom Thoreau admired, regarded the Earth itself as a sacred source of energy. To stretch out on it brought repose, to sit on the ground ensured greater wisdom in councils, to walk in contact with its gravity gave strength and endurance. The Earth was an inexhaustible well of strength: because it was the original Mother, the feeder, but also because it enclosed in its bosom all the dead ancestors. It was the element in which transmission took place. Thus, instead of stretching their hands skyward to implore the mercy of celestial divinities, American Indians preferred to walk barefoot on the Earth: The Lakota was a true Naturist – a lover of Nature. He loved the earth and all things of the earth, the attachment growing with age. The old people came literally to love the soil and they sat or reclined on the ground with a feeling of being close to a mothering power. It was good for the skin to touch the earth and the old people liked to remove their moccasins and walk with bare feet on the sacred earth. Their tipis were built upon the earth and their altars were made of earth. The birds that flew in the air came to rest on the earth and it was the final abiding place of all things that lived and grew. The soil was soothing, strengthening, cleansing and healing. That is why the old Indian still sits upon the earth instead of propping himself up and away from its life-giving forces. For him, to sit or lie upon the ground is to be able to think more deeply and to feel more keenly; he can see more clearly into the mysteries of life and come closer in kinship to other lives about him. Walking, by virtue of having the earth’s support, feeling its gravity, resting on it with every step, is very like a continuous breathing in of energy. But the earth’s force is not transmitted only in the manner of a radiation climbing through the legs. It is also through the coincidence of circulations: walking is movement, the heart beats more strongly, with a more ample beat, the blood circulates faster and more powerfully than when the body is at rest. And the earth’s rhythms draw that along, they echo and respond to each other. A last source of energy, after the heart and the Earth, is landscapes. They summon the walker and make him at home: the hills, the colours, the trees all confirm it. The charm of a twisting path among hills, the beauty of vine fields in autumn, like purple and gold scarves, the silvery glitter of olive leaves against a defining summer sky, the immensity of perfectly sliced glaciers … all these things support, transport and nourish us.
To understand this new frontier, I will have to try to master one of the most difficult and counterintuitive theories ever recorded in the annals of science: quantum physics. Listen to those who have spent their lives immersed in this world and you will have a sense of the challenge we face. After making his groundbreaking discoveries in quantum physics, Werner Heisenberg recalled, "I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?" Einstein declared after one discovery, "If it is correct it signifies the end of science." Schrödinger was so shocked by the implications of what he'd cooked up that he admitted, "I do not like it and I am sorry I had anything to do with it." Nevertheless, quantum physics is now one of the most powerful and well-tested pieces of science on the books. Nothing has come close to pushing it off its pedestal as one of the great scientific achievements of the last century. So there is nothing to do but to dive headfirst into this uncertain world. Feynman has some good advice for me as I embark on my quest: "I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
