Vague Objects, Classical Logic and Standard Mereology
(Metaphysics and Ontology, English)

Paganini (2016) argues that vague objects, e.g. Mount Kilimanjaro, can be accommodated within classical logic and standard mereology, if the reality is gunky. In particular, she argues that Weatherson's argument for inconsistency of vague objects with classical logic and standard mereology is unsound in a gunky reality. This paper constitutes a response. First, It will be argued that in Paganini's gunky theory, vague objects, especially Mount Kilimanjaro, turn out to be precise (non-vague). Second, a generalized version of Weathersons's argument for gunky reality with the same consequence will be presented. The upshot is that the conclusion of Weatherson's argument, this is, inconsistency of vague objects with classical logic and standard mereology, is irresistible, as long as the the central part of assumptions in his argument are granted.

I am a Doctoral Fellow at the MCMP working under supervision of Prof. DDr. Hannes Leitgeb. My main interests lie in language, logic and metaphysics. My current research focuses on logical and metaphysical problems raised by vagueness.
