Single Idea 15538

[filed under theme 7. Existence / D. Theories of Reality / 10. Vagueness / d. Vagueness as linguistic ]

Full Idea

Semantic indecision will suffice to explain the phenomenon of vagueness. [note] Provided that there exist the many precisifications for us to be undecided between. If you deny this, you will indeed have need of vague objects.

Clarification

A 'precisification' is one way of making a vague thing precise

Gist of Idea

Semantic indecision explains vagueness (if we have precisifications to be undecided about)

Source

A Reaction

[He mentions Van Inwagen 1990:213-83] There seem to be three solutions to vague objects: that they really are vague, that they are precise but we can't know precisely, or Lewis's view. I like Lewis's view. Do animals have any problem with vagueness?

The 18 ideas with the same theme [vagueness as indecision about word meanings]:

17431 Vagueness is incomplete definition [Frege, by Koslicki]

9054 Vagueness is only a characteristic of representations, such as language [Russell]

8180 'That is red or orange' might be considered true, even though 'that is red' and 'that is orange' were not [Dummett]
9052 Vague predicates lack application; there are no borderline cases; vague F is not F [Unger, by Keefe/Smith]
15538 Semantic indecision explains vagueness (if we have precisifications to be undecided about) [Lewis]
9057 Vagueness is semantic indecision: we haven't settled quite what our words are meant to express [Lewis]
9671 Whether or not France is hexagonal depends on your standards of precision [Lewis]
16458 Semantic vagueness involves alternative and equal precisifications of the language [Lewis]
17582 Singular terms can be vague, because they can contain predicates, which can be vague [Inwagen]
12023 Vagueness problems arise from applying sharp semantics to vague languages [Forbes,G]
9768 Vagueness is semantic, a deficiency of meaning [Fine,K]
21614 The 'nihilist' view of vagueness says that 'heap' is not a legitimate concept [Williamson]
21617 We can say propositions are bivalent, but vague utterances don't express a proposition [Williamson]
21618 If the vague 'TW is thin' says nothing, what does 'TW is thin if his perfect twin is thin' say? [Williamson]
21625 The vagueness of 'heap' can remain even when the context is fixed [Williamson]
11016 Would a language without vagueness be usable at all? [Read]
