Philosophy of Logic & Mathematics · Whether correct logic is unique

Classical Logical Monism

There is one correct logic, and it is classical logic.

What it claims

Classical logical monism holds that one logic uniquely captures valid inference and that this is classical logic, including noncontradiction, excluded middle, and explosion. Logical laws are universal norms rather than merely tools relative to a purpose. It rejects pluralism about correct consequence relations and the claim that intuitionistic or paraconsistent logic should replace classical validity.
