This parable is one of the most brilliant refutations of Intelligent Design — and of the whole god argument — that I’ve ever read. Here’s an excerpt:
Once upon a time, four blind men were walking in the forest, and they bumped into an elephant.
Moe was in front, and found himself holding the trunk. “It has a tentacle,” he said. “I think we have found a giant squid!”
Larry bumped into the side of the elephant. “It’s a wall,” he said, “A big, bristly wall.”
Curly, at the back, touched the tail. “It’s nothing to worry about, nothing but a piece of rope dangling in the trail.”
Eagletosh saw the interruption as an opportunity to sit in the shade beneath a tree and relax. “It is my considered opinion,” he said, “that whatever it is has feathers. Beautiful iridescent feathers of many hues.”
