Strict-Tolerant consequence as truth-preservation

SZMUC, DAMIÁN ENRIQUE

Workshop; VIII Workshop on Philosophical Logic; 2019

Strict-Tolerant consequence incarnates a way of presenting Classical consequence by means of three-valued models. Given the Strict-Tolerant framework allows for non-transitive extensions, it is sometimes claimed that its characteristic notion of consequence cannot be understood?in a standard or a non-standard way?as truth-preservation. I present an admittedly non-standard way in which this can be carried out.
