Example text

The obvious basis for maintaining that 'She was poor but honest' is defective only in what it implies, not in what it says, is the fact that the most natural dissent would not be 'That is not true' but rather 'You may be right that she was poor and honest, but I wouldn't put it the way you did'. Similarly with sentences that do not have truth values—questions, for example. '; each asks the same question though the latter insinuates something that the former does not. These intuitive responses, which Jackson acknowledges to be the only evidence for judgements about conventional implicature (1981: 133; 1987: 40-1), are a fragile basis for theoretically distinguishing assertion from conventional implicature (§106).

Or, more carefully now, he holds that the truth conditions of A→ C are those of A C, and what is outright asserted by someone who says one is the same as what is asserted by someone who says the other. Grice said this too, but Jackson handles the apparent counterexamples differently, giving primacy to the Ramsey test thesis (1987: 22-32). In presenting these materials, I shall follow Jackson's use of the technical term robust. This word stands for a concept that is present in the Ramsey test: to say that for me Q is fairly (very) robust with respect to P is to say that I accord Q a fairly (very) high probability on the supposition that P is true.

More fully, he asks: 'Why did we need to turn to conventional implicature, rather than conversational, in our . . ' (my emphasis). Instead of considering for the first time how conventional implicature succeeds in explaining how indicatives work, he considers for the second time why conversational implicature fails in this. The earlier point that the Gricean approach must accept Contraposition for indicative conditionals, that is, must regard ¬ C → ¬ A as being no less assertible than A→ C (§10, argument 4), now becomes the point that the Gricean approach must endorse not only Modus Ponens: but also Modus Tollens: It is a sharp point against Grice; perhaps it deserves to be presented twice in these two guises.
