In the wildest nature, there is not only the material of the most cultivated life, and a sort of anticipation of the last result, but a greater refinement already than is ever attained by man.... Nature is prepared to welcome into her scenery the finest work of human art, for she is herself an art so cunning that the artist never appears in his work. - Henry David Thoreau
