Yet Another Argument for Non-contradiction

Key Points

The main aim is to establish a new argument supporting the principle that contradictory statements cannot both be true.
Developed a new argument based on extra-logical premises.
Analyzed the validity of the argument across various logics, including paraconsistent logics.
Demonstrated the argument's validity in multiple logical frameworks.
Provided a justification for the law of non-contradiction that is not tied to a specific logical system.

Abstract

Abstract I offer a new argument for the principle that there are no true contradictions. Because the argument relies mostly on extra-logical premises and is valid in a wide range of logics (including certain paraconsistent logics), it offers a logic-neutral justification of the law of non-contradiction.
