"I stand in awe of my body, this matter to which I am bound has become so strange to me. i fear not spirits, ghosts, of which I am one . . .but I fear bodies, I tremble to meet them. What is this Titan that has possession of me? Talk of mysteries! - Think of our life in nature, -daily to be shown matter, to come into contact with it, -rocks, trees, wind on our cheeks! the solid earth! the actual world! the common sense! Contact! Contact! Who are we? where are we?" - Thoreau, "Ktaadn and the Maine Woods," 1848.
