Fuzzy Logic and Theories of Vagueness
Fuzzy Logic has been successfully applied to all kinds of scenarios, where degrees of membership and truth can be systematically discerned. However it is highly contentious whether this fact renders Fuzzy Logic an ideal tool for modelling reasoning with vague concepts and propositions. There is a lively and prolific debate in analytic philosophy about so-called theories of vagueness. Interestin...
متن کاملA Conversation About Fuzzy Logic and Vagueness
CF: I am flattered by this reference to my own work. But we should let our intended audience know a bit a more about the background of those two contributions. I still remember that I imagined to be quite bold and provocative by submitting a paper to a workshop on Soft Computing—organized by you, by the way, in 2003—that suggested already in the title that logicians should not just presume that...
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 کاملVagueness, Logic and Use: Some Experimental Results
Although the use of experimental data is a somewhat new methodology for philosophers, research on vagueness is poised to make excellent gains from the approach. This is because any theory that purports to explain the vagueness of natural language can benefit from data about how ordinary speakers use vague words. Nonetheless, we must carefully consider the kind of evidence that we're interested ...
متن کاملIn Which Sense Is Fuzzy Logic a Logic for Vagueness?
The problem of artificial precision demonstrates the inadequacy of näıve fuzzy semantics for vagueness. This problem is, nevertheless, satisfactorily remedied by fuzzy plurivaluationism; i.e., by taking a class of fuzzy models (a fuzzy plurivaluation), instead of a single fuzzy model, for the semantics of a vague concept. Such a fuzzy plurivaluation in turn represents the class of models of a f...
