The sheet is not the only thing that has been muddied in this questionable example. The cow is NOT where he thinks it is and therefore he does NOT have knowledge of it being there. It’s near where he thinks it is but that distinction makes all the difference in the world.
Also there’s a whole slew of problems arising from the way our cognition interprets sensory information. For instance, our eyes enable us to see light in various colors and intensities but they arguably don’t see objects (or subjects). In that sense we cannot hold JTB about cows, anyway, because even as a farmer we cannot be sure we’ve ever seen one.
(Never mind the next problem, which is that even our sensory facilities might be corrupted by color blindness, myopia, etc…)
