 The contrast here with indexicals is apparently quite sharp. If I say “I’m hungry”, and you’re not hungry, you’d never reply to my utterance by saying “No, I’m not hungry”—precisely because it’s obvious that we would not be disagreeing. So again we have a puzzle: a puzzle about how each of our “soup” sentences could express true propositions, despite those propositions contradicting each other. Relativism suggests an answer: these propositions are only true or false relative to individuals. The one I express is true relative to me, and its negation is true relative to you; they’re contradictory in the sense that it is impossible for both to be true relative to the same individual (at the same time).
