P. H. Nowell-Smith and H. P. Grice: "Odd, even *logically* odd, if Nowell-Smith insists -- but highly true!"

logical oddness: P. H. Nowell-Smith’s term, referring to the denial of contextual implications. If P contextually implies Q, then to assert P we would naturally assert Q. But if one asserts P, but denies Q, or asks whether Q, one acts in a way that is logically odd. In the former case, the person denying Q is in a self-contradiction. In the latter case, the answer to the person’s question has already been implied, and no further or better answer can be expected to be given. “I shall say that a question is ‘logically odd’ if there appears to be no further room for it in its context because it has already been answered.” Nowell-Smith, Ethics
