Single Idea 9051

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

Full Idea

Russell takes it that logic assumes precision, and since natural language is not precise it cannot be in the province of logic at all.

Gist of Idea

Since natural language is not precise it cannot be in the province of logic

report of Bertrand Russell (Vagueness [1923]) by R Keefe / P Smith - Intro: Theories of Vagueness §1

A Reaction

I find this view congenial. It seems to me that the necessary prelude to logic is to do everything you can to eliminate ambiguity and vagueness from the sentences at issue. We want the proposition, or logical form. If there isn't one, forget it?

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]
