Core logic

This article explains the term minimal logic in the sense of core logic , for a different meaning see systems of natural reasoning .

The core logic , also the core of logic or minimal logic , is that part of logic without which an argumentation is not possible. It has a special position insofar as it cannot be revised within an argument because every attempt at argumentation and revision already requires it. It can therefore only be abandoned together with the argumentation itself.

From a transcendental pragmatic point of view, the core logic can be constituted by examining which rules are necessary to refute the simplest refutable system. This is the system that consists only of the two statements and . ${\displaystyle A}$ ${\displaystyle \neg A}$

David Miller is of the opinion that this reasoning is based on an insufficient separation of criticism and reasoning and is inadmissible; the core logic can be revised in principle.
