Wilhelm, what is the world to our hearts without love? It is a magic lantern without light. You have but to set up the light within, and the brightest pictures are thrown on the white screen; and if that were all there is, fleeting shadows, we are yet happy, when, like children, we behold them and are transported with the wonderful sight.
Goethe, The Sorrows of Young Werther, July 18, Book I
