Three logicians walk into a bar ...
I recall that when I was a kid in elementary school, teachers would often ask the class questions like, "Does everyone want X?" or "Does anyone want X?" My reaction, which I never actually said aloud, was: "How should I know? I only know what I want or don't want. Even if I want something, I can't possibly know whether everyone else does. And even if I don't want it, someone else might."
Of course, the teachers were just speaking imprecisely, as adults often do, and we all sort-of-understood that. But under special circumstances, it's hypothetically possible to answer such questions in literal and logically precise terms. This shows how.
Follow-up: Mike Lewis, responding by e-mail, makes a good point:
Question could be asked so as to suggest the answer. See Jedi mind trick.
For example, classroom is asked if everyone wants to take a nap. Nice way of saying it's nap time.
To which I responded: Precisely. Like a lot of expressions used all the time in everyday life (and not only with children), the questions aren't meant to be taken literally.
But when I was a kid, I found it difficult to ignore the fact that, taken literally, the questions didn't make logical sense. Strange things are running through kids' minds all the time, aren't they?
=> And as a Wittgensteinian might ask, isn't there a family resemblance between a Jedi mind trick and an Austinian "performative utterance"? Or could we simply describe these formulations, more legalistically, as leading questions?
