Title
Vagueness Modeled in a Relevance Logic

Synopsis
A well-known property of natural languages is that they are imprecise; for example, they contain vague terms such as ‘bald’ and ‘a heap’. Philosophers have been debating related paradoxes (like the Sorites) for more than 2,000 years. Classical logic is based on the idea that a predicate either holds or does not hold of an object, but not both. Some many-valued logics have been used to deal with vagueness. I will show that a relevance logic, R-Mingle is more suitable to model vagueness.
