Strange day at work. Something was happening that made many people think I should be happy, and maybe I could have been happy about it, but I was more on the bitter side of things. Then a student asked, "Why are we bothering to do this?" and hope emerged, "Because maybe in the future we will be ..." It was a moment of light that lifted me up a bit.
In 1801 Thomas Young theorized that humans could not see all the wavelengths of light. He was right. There are animals that can see what we can't, but we can see more than most mammals, which as a group lost color vision--- don't use it, you will lose it--- because they were nocturnal. But a mutation gave us the chance to emerge from darkness, and a primate took it and made a run for it.
“I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.” (John 8:12).
In 1993 Shirley Horn released a CD called Light Out of Darkness. Can you imagine a better title to a tribute to Ray Charles? Can you imagine Ray Charles singing with a frog?
