It seems true to say that Sherlock Holmes is a detective, despite there being no Sherlock Holmes. When asked to explain this fact, philosophers of language often opt for some version of Lewis’s view that sentences like ‘Sherlock Holmes is a detective’ may be taken as abbreviations for sentences prefixed with ‘In the Sherlock Holmes stories …’. I present two problems for this view. First, I provide reason to deny that these sentences are abbreviations. In short, these sentences have aesthetic (...) properties that we should not expect of abbreviations. Second, I argue that the apparent truth of these sentences would not be explained even if they were abbreviations. An alternative is presented that avoids these problems. Following Walton, talk about fiction is viewed as a game of make-believe; following Lewis, interpretations of fiction are modelled using possible worlds. (shrink)

ABSTRACT The truth-conditions of utterances are often underdetermined by the meaning of the sentence uttered, as suggested by the observation that the same sentence has different intuitive truth-values in different contexts. The intuitive difference is usually explained by assigning different truth-conditions to different utterances. This paper poses a problem for explanations of this kind: These truth-conditions, if they exist, are epistemically inaccessible. I suggest instead that truth-conditional underdetermination is ineliminable and these utterances have no truth-conditions. Intuitive truth-values are explained by (...) the effect that all the most reasonable interpretations have on the common ground: An utterance is intuitively true when it is true on all interpretations that answer the question under discussion.

This paper summarises the contributions to our Topical Collection on indeterminacy and underdetermination. The collection includes papers in ethics, metaethics, logic, metaphysics, epistemology, philosophy of science, philosophy of language and philosophy of computation.

Generic generalisations like ‘Opioids are highly addictive’ are very useful in scientific communication, but they can often be interpreted in many different ways. Although this is not a problem when all interpretations provide the same answer to the question under discussion, a problem arises when a generic generalisation is used to answer a question other than that originally intended. In such cases, some interpretations of the generalisation might answer the question in a way that the original speaker would not endorse. (...) Rather than excising generic generalisations from scientific communication, I recommend that scientific communicators carefully consider the kinds of questions their words might be taken to answer and try to avoid phrasing that might be taken to provide unintended answers.

The debate over the meanings of indexical expressions has relied heavily on the method of counterexamples. This paper challenges that method by showing that purported counterexamples can often be explained away by appeal to perspective shifts. For these counterexamples to establish anything about indexical reference, we must identify the conditions under which theorists can legitimately appeal to perspective shifts. Some tests for semantic content are considered and it is argued that none of them can tell us when appeal to perspective (...) shift is admissible. The paper then considers how we should proceed if we become convinced that there is no way to identify the content of indexical expressions, offering reasons in favour of a nihilist conception of character over an epistemicist or pluralist conception.
