Justification of Logics - Epistemology or Metaphysics? Both!
Abstract:
In recent work I tried to show that systems of non-classical logic can be translated into systems of (extended) classical logic, under preservation of meaning. This implies that the justification of a system of logic has an epistemological and a metaphysical dimension: In the epistemological dimension, it is asked: Which system of logic is most universal in regard to its power of representation? Since non-classical logics can be translated into classical logic, I argue that in this dimension classical logic is preferable, in particular as a universal meta-logic. In the metaphysical dimension it is asked: Which system of logical operators - whether they are represented in classical logic or in a non-classical logic - is most adequate for describing a particular domain? This is a question of an inductive metaphysics that involves, beyond simplicity considerations, abductive inferences from empirically given data.
