Higher-Order Vagueness and the Vagueness of ‘Vague’
Sorensen (1985) has argued that ‘vague’ is itself a vague predicate; it is just as sorites-prone as its positive instances. This result has been exploited by Hyde (1994) in an ingenious attempt to establish that vague predicates must necessarily suffer from higher-order vagueness. More precisely, Hyde has argued that the vagueness of ‘vague’ ensures that the “paradigmatic conception”, according...
متن کاملFuzzy Logic and Higher-Order Vagueness
The major reason given in the philosophical literature for dissatisfaction with theories of vagueness based on fuzzy logic is that such theories give rise to a problem of higherorder vagueness or artificial precision. In this paper I first outline the problem and survey suggested solutions: fuzzy epistemicism; measuring truth on an ordinal scale; logic as modelling; fuzzy metalanguages; blurry ...
متن کاملRough Sets and Higher Order Vagueness
We present a rough set approach to vague concept approximation within the adaptive learning framework. In particular, the role of extensions of approximation spaces in searching for concept approximation is emphasized. Boundary regions of approximated concepts within the adaptive learning framework are satisfying the higher order vagueness condition, i.e., the boundary regions of vague concepts...
متن کاملA Paradox of Higher-Order Vagueness
The naive approach to vagueness maintains that the nature of the vagueness of an expression basically consists in its not having boundaries between positive and negative cases of application in an appropriate ordering (a “soritical series”), whilst having both positive and negative cases in it. The naive approach is contrasted with the nowadays dominant approach to vagueness, maintaining that t...
متن کاملHigher-order Vagueness and Borderline Nestings – a Persistent Confusion
This paper shows that authors who have recently argued that higher-order vagueness is incoherent, paradoxical, illusory or non-existent invariably confound elements of higher-order vagueness (of the kind relevant to the Sorites paradox) with elements of a different paradigm of borderline borderline cases; and that, once the elements of that other paradigm are removed from the description of hig...
