 But for his part, W. thinks apriori knowledge of (2) should not be surrendered. Instead, he claims we should not assume that the warrant for (3) is inevitably empirical. For (3) ordinarily has a non-empirical “default” warrant. So given that (2) presupposes (3), a non-empirical warrant for (3) makes possible an apriori warrant for (2). Even so, W. is quick to remind us that a default warrant for (3) is too “thin” to prove (3).
