“It would be wholly impossible for me to say whether this cloudy, silently disturbed, unraveled sky is mirrored in my soul or the reverse, whether or not I read the image of my own inner life in this sky. Sometimes everything is so completely uncertain! There are days when I am convinced that no man on earth can recognize certain moods of air and cloud, certain tones of color, certain fragrances and movements of moisture as finely, as exactly, and as truly as I can, with my old, nervous sense of poet and wanderer. And then again, as today, it can be doubtful to me whether I have seen, heard, and smelled anything after all, whether everything that I took to be true is not merely an image cast outward, the image of my inner life.”
