 Stopped Clock is a case in which a person correctly believes that the time is, say, 1:00 p.m. on the basis of looking at a clock that reads 1:00 o’clock, and which he is justified in thinking is working properly. However, the clock stopped working exactly twenty-four hours earlier. Still, that person has a justified true belief that it is 1:00 p.m. Sheep is a case where a jokester farmer breeds poodles to look like sheep, and grooms them so they are indistinguishable from real sheep. He puts them in his field for tourists to see, and his real sheep are in that field but out of sight behind some large boulders where he feeds them. Jones drives by and forms the justified true belief that there are sheep in the field. It seems that the intuitions that knowledge is absent, but JTB present, in Stopped Clock and Sheep are enough to make it reasonable to reject the JTB theory of knowledge. A few really strong intuitions seem enough by themselves to make it reasonable to reject a theory. Contra Weatherson, reasonable rejection does not require that the theory disagree with virtually all intuitions. Theoretical virtues are not enough to overcome such intuitive shortcomings even if there is not a competing virtuous theoretical analysis available.
