 However, when we look at the items of Johnston’s list, it seems difficult to maintain this view about the status of the various items. Take item (5), Revelation. Whatever its status, it doesn’t look like a folk belief. It looks more like something a philosopher might come up with. In the second place, it seems to have a peculiar status. Experiences of color, it is claimed, are enough to inform us of the nature of color. If it is true or if it is a folk belief, it is hard to see what need there is of the other items in the list. Perhaps, though, this formulation of the doctrine is misleading, and there is a better formulation available. One possibility is that the doctrine should be interpreted as addressing certain necessary conditions, rather than all necessary conditions, or all necessary and sufficient conditions. This point is important since there is group of philosophers who are sympathetic to Primitivism and/or Naïve Realism, who seem to favor a principle that differs in this way from Johnston’s formulation  (see section 2.1).
