Making Exceptions

Anti-exceptionalism about logic, in its original Quinean incarnation, may be summarized as the thesis that logic is, in effect, simply a deeply entrenched part of empirical-scientific theory. It may thus be taken to involve two principal, distinguishable claims: First, Corroboration—that the epistemic good standing of logical principles is properly earned in the same way as the confirmation of all empirical scientific laws. We are justified in accepting such principles by, and only by, their participation in ongoing successful empirical-scientific theory. Second, Rejection—that, as with empirical-scientific hypotheses, logical principles are one and all in principle open to rational rejection or revision on purely empirical grounds if the system in which they are participant runs into "recalcitrant experience" and such an adjustment promises to smooth out the wrinkles. It is argued that neither claim can be sustained in full generality.
