Rationally Speaking: Peas and quiet

But we have to be careful: science isn't in the business of confirming our intuitions, and so our everyday terms may not be adequate to capture the weird, wild, wondrous things that science finds. It's fascinating that peas can send warning signals to one another, but that doesn't mean that those peas are talking, even if "talk" is the term that most easily describes what the peas are doing (6). Once we lose track of our linguistic limits, we fall prey to the dangers of rhetoric.
