 The normative premise, [P1], is perfectly general and hence may be equally deployed to undermine justified belief of any proposition failing its standard. Indeed, there seems equally good reason to think that the propositions which are the contents of most philosophical intuitions will not be part (outside of attitude contexts) of the best explanation of our having those intuitions. (See Goldman 1989, 1992 for similar skeptical arguments regarding the use of intuitions in contemporary metaphysics.)
