 Finally, (a) the justification for the normative and the non-normative premises must be provided by some source of evidence or justification other than intuitions of the sort impugned by the argument and (b) we must lack good reason to think that our belief in the normative or factual premise fails the necessary condition on justified belief advanced by the normative premise. Call the conjunction of these requirements “the non-self-undermining constraint” (Bealer 1992; Pust 2001; but see Silva 2013). While running afoul of this constraint does not provide reason to think the argument at issue unsound, it appears a reasonable constraint on a skeptical argument meant to produce reflectively justified belief in a conclusion in virtue of its following from justified premises. Given that the proponents of the various skeptical arguments to be discussed are mere local skeptics, they certainly appear to be offering arguments aimed at inducing philosophically reasonable belief in a local skeptical thesis regarding intuition.
