Fuzzy Logic and Higher-Order Vagueness |
|
Συγγραφέας: Nicholas J.J. Smith Nicholas J.J. Smith: Fuzzy Logic and Higher-Order Vagueness (pdf, 19 pages) 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.1 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 sets; and fuzzy plurivaluationism. I then argue that in order to decide upon a solution, we need to understand the true nature and source of the problem. Two possible sources are discussed: the problem stems from the very nature of vaguenessâfrom the defining features of vague predicates; or the problem stems from the way in which the meanings of predicates are determinedâby the usage of speakers together with facts about their environment and so on. I argue that the latter is the true source of the problem, and on this basis that fuzzy plurivaluationism is the correct solution. |
