That's a pretty arbitrary standard you might be imposing there.....
Make a poetic comment in the wrong venue, & there goes one's standing as a scientist, regardless of the quality of one's work.
I'm not judging his material or even saying that his metaphor is wrong.
The question, again, was if this is science. Not if it's a good metaphor. Not if it's palatable to every person. Not if it's right or wrong. The question was "is ... science."
And no, metaphors aren't science. Just like analogies aren't science either. Words aren't science either. Science is the study of nature.
Of course, no one is claiming that.
That's not what the title to the thread asks.
The title asks if the claim that the eye was designed by an idiot is science, and it's not. It's hyperbole and metaphorical, but not science.
I agree that it's not appropriate for a textbook.
If it's science it would have to be. Science textbooks contain scientific statements, claims, facts, and information, and if "idiot designer" is a scientific statement, it should be in science textbooks.
Is it science or not? No. We can't start accepting metaphors to be scientific truths.
But Dawkins is a provocateur, & this doesn't make his work non-science.
I didn't say his work is non-science. His work is. His metaphors aren't science though. Just like every other metaphor or analogy used in the past to explain scientific theories aren't science in themselves, they're just metaphors and analogies of science. They're not science itself.
The whole question is wrong to begin with. This whole thread is based on a flawed question. A popularized book to give a cursory insight in science written by a scientist isn't the same as science. It's just a book. It's not a science textbook. And it will be based on the author's bias and personal views. There's no peer review on such books.
