The other face of the skin

If the Earth were a human body, the surface of the stone is his skin with its roughness, transparency, colors, touched by light grazing or diffuse, with its slow transformation. It would be like a skin eternal, unlike ours, a skin which can trace the history of humanity as a whole. You want to touch it until it sank in its clarity, to search for items in its folds to recapture that already existed in our thoughts always. To penetrate this negative and positive, as the perception of an inside and an outside. And 'stone, is matter, is the skin of nature.
