Tim Williamson is an anti-exceptionalist about logic. He thinks that the method of justification for logic is abductive, broadly the same as that used for justifying scientific theories. Anti-exceptionalism’s rival, exceptionalism, is often characterised by anti-exceptionalists as the view that logic is a priori, justified through rational intuition or conceptual understanding. I argue that there is much less of a conflict between the two views than is usually thought. This is because they are engaged in different epistemological projects: anti-exceptionalism is a view about how to go about justifying whole logical theories, while exceptionalism is a view about how we might be justified in believing certain basic logical principles.
