Something that stayed with me since I first read George Mc Donald's beautiful story, "The Day Boy and the Night Girl"(The Romance of Photogen and Nycteris). I quote: "She followed the firefly, which, like herself, was seeking the way out. If it did not know the way, it was yet light; and, because all light is one, any light may serve to guide to more light. If she was mistaken in thinking it the spirit of her lamp, it was of the same spirit as her lamp and had wings". An excellent weekend reading that I strongly recommend especially now that light works it's way to gaining more ground every day...
