 Third, the red barn case is one about which intuitions will vary. It is not obvious that I do know there is a red barn in the circumstances Dretske sketches, which differ from those in Ginet’s original barn case (where I fail to know barn) only in the stipulations that I see a red barn and that none of the barn simulacra are red. What is more, both Dretske’s and Nozick’s accounts have the odd implication that I know there is a barn if I base my belief on my red barn percepts yet I fail to know this if, in basing it on my barn percepts, I ignore the barn’s color. Presumably the barn’s color is not relevant to its being a barn.
