Sorites Paradox and the Need for Many-Valued Logics
Original language description
Sorites paradoxes are a class of paradoxical arguments which arise as a result of using vague terms such as "heap" or "bald". While precise terms have sharp boundaries of application, vague terms lack such precise boundaries. With vague terms there are objects to which: a) the vague term applies, b) the vague term doesn?t apply, and c) it is uncertain whether vague term applies or not (so called borderline cases). In borderline cases it is uncertain whether the vague term in question applies to them ornot. Moreover, this uncertainty cannot be resolved by any enquiry. Since there are three aforementioned classes into which we can divide objects in a range of significance of any vague term, it might be tempting to use three-valued logic to deal with sorites paradoxes. This way we can ascribe exactly one truth value to all sentences of sorites paradox and we needn't resort to either supervaluationism or subvaluationism.
