 How could two logics both be correct, when they disagree about which arguments are valid? One way is if there is more than one relation of logical consequence (and so more than one interpretation of ‘valid’) so that one of the logics captures validity in one sense, while its rival captures validity in another. Pluralists commonly elaborate on this by maintaining that natural language expressions like ‘follows from’ are unsettled, vague, or ambiguous, and may be settled, made more precise, or disambiguated, in more than one way (Shapiro 2014, 1–2).
