 [A8] renders all rational intuitions overtly modal in content and, on a view of concept possession according to which possessing the concept c at t requires the ability to deploy c in thought at t, requires a level of sophistication not obviously had by the philosophical innocent who is, nonetheless, presumably capable of having a rational intuition (Pust 2000: 38; Ludwig 2007: 136). Moreover, possibility intuitions are also essential to philosophical practice and if the proponent of [A8] wishes to include possibility claims as the contents of intuitions (rather than treating them as inferentially justified by a rational intuition and the principle that what is necessarily possible is possible), then they must treat such intuitions as possessed of an iterated modal propositional content.
