"Do you understand how there could be any writing in a spider's web?"
"Oh, no," said Dr. Dorian. "I don't understand it. But for that matter I don't understand how a spider learned to spin a web in the first place. When the words appeared, everyone said they were a miracle. But nobody pointed out that the web itself is a miracle."
"What's miraculous about a spider's web?" said Mrs. Arable. "I don't see why you say a web is a miracle-it's just a web."
"Ever try to spin one?" asked Dr. Dorian."
