“There is a part of everything that remains unexplored, for we have fallen into the habit of remembering, whenever we use our eyes, what people before us have thought of the thing we are looking at. Even the slightest thing contains a little that is unknown. We must find it. To describe a blazing fire or a tree in a plain, we must remain before that fire or that tree until they no longer resemble for us any other tree or any other fire.”
