Saw this:
which made me think of this:
Have you heard about the words that appeared in the spider's web?" asked Mrs. Arable nervously.
"Yes," replied the doctor.
"Well, do you understand it?" asked Mrs. Arable.
"Understand what?"
"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.
Mrs. Arable shifted uneasily in her chair. "No," she replied. "But I can crochet a doily and I can knit a sock."
"Sure," said the doctor. "But somebody taught you, didn't they?"
"My mother taught me.""Well, who taught a spider? A young spider knows how to spin a web without any instructions from anybody. Don't you regard that as a miracle?"
"I suppose so," said Mrs. Arable. "I never looked at it that way before. Still, I don't understand it, and I don't like what I can't understand."
"None of us do," said Dr. Dorian, sighing. "I'm a doctor. Doctors are supposed to understand everything. But I don't understand everything, and I don't intend to let it worry me."
