Two-valued logics for naive truth theory
Lucas Rosenblatt · The Australasian Journal of Logic · 2015
It is part of the current wisdom that the Liar and similar semanticparadoxes can be taken care of by the use of certain non-classicalmultivalued logics. In this paper I want to suggest that bivalent logic can do just as well. This is accomplished by using a non-deterministic matrix to define the negation connective. I show that the systems obtained in this way support a transparent truth predicate. The paper also contains some remarks on the conceptual interest of such systems.
