“The people who were sitting in darkness saw a great Light, and those who were sitting in the land and shadow of death, upon them a Light dawned.”
If there is any such thing as a universal symbol, it just might be light.
In every place and culture all around the world, everybody instinctively associates light with things like truth and insight and joy. Whether it’s our Christmas, or the Hanukkah of Judaism, or Chinese New Year, or some other “festival of light”, it always seems to point to the same sorts of experience: that of being able to see, whereas before, one could not. Is not the celebrated historical period of the secular skeptics called “The Enlightenment”? Even the irreligious are drawn to this symbolism.
