Thou only has taught me that I have a heart – thou only hast thrown a light deep downward and upward into my soul. Thou only hast revealed me to myself; for without thy aid my best knowledge of myself would have been merely to know my own shadow – to watch it flickering on the wall, and mistake its fantasies for my own real actions … Now, dearest, dost thou under- stand what thou hast done for me ? And is it not a somewhat fearful thought, that a few slight circumstances might have pre- vented us from meeting ? Nathaniel Hawthorne, a letter to Sophia Peadbody 4 October 1840
