According to relativism, these appearances of faultless disagreement are to be endorsed. According to moderate relativism, this can be done within the general Kaplan-Lewis-Stalnaker two-dimensional framework, in which the basic semantic notion is that of a sentence s being true at a context c at the index i: it may in effect be the case that s is true at c (at its index ic) but false at c∗ (at ic∗). According to indexical (moderate) relativism, this is so in virtue of the content of sentence s at c being different from that of s at c∗.

I want to discuss a puzzle about the semantics of epistemic modals, like “It might be the case that” as it occurs in “It might be the case that Goldbach’s conjecture is false.”1 I’ll argue that the puzzle cannot be adequately explained on standard accounts of the semantics of epistemic modals, and that a proper solution requires relativizing utterance truth to a context of assessment, a semantic device whose utility and coherence I have defended elsewhere for future contingents (MacFarlane..

I think that there are good reasons to adopt a relativist semantics for epistemic modal claims such as ``the treasure might be under the palm tree'', according to which such utterances determine a truth value relative to something finer-grained than just a world (or a <world, time> pair). Anyone who is inclined to relativise truth to more than just worlds and times faces a problem about assertion. It's easy to be puzzled about just what purpose would be served by assertions of this kind, and how to understand what we'd be up to in our use of sentences like ``the treasure might be under the palm tree'', if they have such peculiar truth conditions. After providing a very quick argument to motivate a relativist view of epistemic modals, I bring out and attempt to resolve this problem in making sense of the role of assertions with relativist truth conditions. Solving this problem should be helpful in two ways: first, it eliminates an apparently forceful objection to relativism, and second, spelling out the relativist account of assertion and communication will help to make clear just what the relativist position is, exactly, and why it's interesting.

In the paper we argue that truth-relativism is potentially hostage to a problem of exhibiting witnesses of its own truth. The problem for the relativist stems from acceptance of a trumping principle according to which there is a dependency between ascriptions of truth of an utterance and ascriptions of truth to other ascriptions of truth of that utterance. We argue that such a dependency indeed holds in the case of future contingents and the case of epistemic modals and that, consequently, the relativist about these domains cannot exhibit witnesses to his relativism. In the appendix we provide some results on the relation between trumping and multi-order relativism.

Responds to an argument against relativist semantics advanced in Cappelen and Hawthorne’s Relativism and Monadic Truth.

The goal of this paper is to make sense of relativism about truth. There are two key ideas. (1) To be a relativist about truth is to allow that a sentence or proposition might be assessment-sensitive: that is, its truth value might vary with the context of assessment as well as the context of use. (2) Making sense of relativism is a matter of understanding what it would be to commit oneself to the truth of an assessment-sensitive sentence or proposition.

Relativism, in the sense at issue here, is a view about the meaning of knowledge attributions—statements of the form “S knows that p.” Like contextualism, it holds that the truth of knowledge claims is sensitive to contextual factors, such as which alternatives are relevant at the context, or how high the stakes are. For the relativist, however, the relevant context is the context from which the knowledge claim is being assessed, not the context at which it was made.

Both context relativists and circumstance-of-evaluation relativists agree that the traditional semantic interpretation of some sentence-types fails to deliver the adequate truth-conditions for the corresponding tokens. But while the context relativists argue that the truth-conditions of each token depend on its context of utterance—each token being thus associated with a distinct intension—circumstance-of-evaluation relativists preserve a unique intension for all the tokens by placing circumstances of evaluations under the influence of a certain ‘point of view’. The main difference between the two approaches is that only the former can operate locally. It is shown that, for this reason, circumstance-of-evaluation relativism makes erroneous semantic predictions about (relative) gradable adjectives.

In the paper we argue that truth-relativism is potentially hostage to a problem of exhibiting witnesses of its own truth. The problem for the relativist stems from acceptance of a trumping principle according to which there is a dependency between ascriptions of truth of an utterance and ascriptions of truth to other ascriptions of truth of that utterance. We argue that such a dependency indeed holds in the case of future contingents and the case of epistemic modals and that, consequently, the relativist about these domains cannot exhibit witnesses to his relativism. In the appendix we provide some results on the relation between trumping and multi-order relativism.

I set out and defend a view on indicative conditionals that I call “indexical relativism”. The core of the view is that which proposition is (semantically) expressed by an utterance of a conditional is a function of (among other things) the speaker’s context and the assessor’s context. This implies a kind of relativism, namely that a single utterance may be correctly assessed as true by one assessor and false by another.
