 You think to yourself, “I shouldn’t drink another Dr. Pepper. I’ve had two already”. But the claim that you shouldn’t drink another seems like a very different kind of claim than the claim that you’ve had two Dr. Peppers already. Broadly (and vaguely) speaking, the first claim tells us something action-guiding, whereas the second does not. The first tells us something about your reasons for acting or thinking a certain way; the second, by itself, does not. In sum, the first is a normative claim, whereas the second is not.
