Moore's Proof to Wittgenstein: I Hold My Hand in Front of It

Wittgenstein is not disputing the certainty, so to speak, at least the initial Prumifatia certainty of Moore's assertion. In fact, he says, oh my God, he's highlighted. this class of propositions that certainly do seem to be unimpeachable,. right? Noncontrovertible. He's just confused and he's concerned. So a couple of things that come out of it is he says, they seem like they're empirical propositions, like there is a cat on the mat that could be verified, but they're not. They look like propositions like that, but they are not.
