 A standard contemporary logical view has it that, from contradictory premises, anything follows. A logical consequence relation is explosive if according to it any arbitrary conclusion \(B\) is entailed by any arbitrary contradiction \(A\), \(\neg A\) (ex contradictione quodlibet (ECQ)). Classical logic, and most standard ‘non-classical’ logics too such as intuitionist logic, are explosive. Inconsistency, according to received wisdom, cannot be coherently reasoned about.
