Context, interest relativity and the sorites

چکیده
According to what I will call a contextualist solution to the sorites paradox, vague terms are context-sensitive, and one can give a convincing dissolution of the sorites paradox in terms of this context-dependency. The reason, according to the contextualist, that precise boundaries for expressions like “heap” or “tall for a basketball player” are so difficult to detect is that when two entities are sufficiently similar (or saliently similar), we tend to shift the interpretation of the vague expression so that if one counts as falling in the extension of the property expressed by that expression, so does the other. As a consequence, when we look for the boundary of the extension of a vague expression in its penumbra, our very looking has the effect of changing the interpretation of the vague expression so that the boundary is not where we are looking. This accounts for the persuasive force of sorites arguments. Suppose we are presented with fifty piles each of which has one grain less than the pile to its left. On the far left is a pile we are strongly inclined to call a heap when presented alone. This pile is in the definite extension of “heap”. On the far right is a pile we are slightly inclined not to call a heap when presented alone. It is towards the end of the penumbra of “heap”. But starting with the left-most pile (pile 1), we may make progressive judgements of the form:

Context-Dependence and the Sorites
In Section 1 we describe the Sorites paradox and lay out options for a solution. In Section 2 we consider approaches which deny that all premises are true, and note that these solutions all seem open to a certain serious objection. In Section 3 we note a problem for the principle of transitivity of the conditional and present a contextualist resolution of the problem, according to which the “co...
متن کاملVagueness as Semantic
I shall argue that vagueness, understood as a semantic phenomenon, can be accommodated within standard semantics by assimilating it to contingency in standard modal semantics and suitably modifying the pragmatics. I claim that vagueness in natural language is not a defect and that accommodating it is therefore obligatory for semantic frameworks for natural languages. In section 17.2, I interpre...
متن کاملSorites without Vagueness Ii: Comparative Sorites
We develop a mathematical theory for comparative sorites, considered in terms of a system mapping pairs of stimuli into a binary response characteristic whose values supervene on stimulus pairs and are interpretable as the complementary relations ‘are the same’ and ‘are not the same’ (overall or in some respect). Comparative sorites is about hypothetical sequences of stimuli in which every two ...
متن کاملVague Desire: The Sorites and the Money Pump
An important foundational project in understanding language use is the Gricean [3] program of reducing meaning to communicative intentions. Here I will fill in some details in the Gricean picture, by outlining how linguistic vagueness arises from indeterminacies in preferences, as studied in models from economics and psychology. (The proposal is related to Fara’s [2] treatment of “vague desire”...
