The two were sometimes seen as irreconcilable. Classical logic was the reconciliation of Aristotles logic, which dominated most of the last 2000 years, with the propositional Stoic logic. The name does not refer to classical antiquity, which used the term logic of Aristotle. But recent decades have seen growing interest in deviant, paraconsistent systems that include non-explosive relations of logical consequence. Classical logic is a 19th and 20th-century innovation. accessibility: lattice representations for semantics of non-classical and modal logics. According to classical systems of logic, anything follows from a contradiction: the relation of logical consequence is explosive. Priest 2001 is a general introduction to propositional modal. Stewart Shapiro - 2003 - Review of Metaphysics 56 (3):670-672. Maureen Eckert (left) and Graham Priest (right) on deviant logic.

Priests support for paraconsistent logic: Both logicians find classical. Graham Priest - 2000 - Oxford, England: Oxford University Press. A rationale for calling such a world impossible is simply that such a pair of sentences can be true in no classical interpretation.

This is naturally construed as the formal representative of the actual world. The full range of options may be seen more clearly as a flow chart, shown in. It is common enough in work on relevant logics using Routley-Meyer frames to talk about a real world. I close by exploring some of the philosophical consequences of the addition.

Straightforward ways of doing this are in tension with standard motivations for relevant logics, but I show how to add the operator in a way that permits one to maintain the intuitions behind relevant logics. This document collects natural derivation systems for logics described in Priest, An Introduction to Non-Classical Logic 4. In this paper, I motivate the addition of an actuality operator to relevant logics.
