 Accepting contradictions. There is also another direction into which Kilvington’s comments can be developed. In another comment on the example D2 above, Kilvington says that the respondent could grant Proposition 1 and deny Proposition 2 (S47, (bb); Kretzmann &amp; Kretzmann 1990b, 131). His point is that when the propositions ‘you are in Rome’ and ‘you are a bishop’ are claimed to be similar in truth value, they are mentioned rather than used. Given that the meanings of these strings of words is not logically necessary, it might be that Proposition 1 (claiming that the two mentioned propositions are similar in truth value) has nothing to do with the respondent being in Rome or being a bishop. Thus, Proposition 2 does not follow from the positum and Proposition 1 together.
