 There are a number of other arguments from ignorance in the literature—for example, the case of Rudolph Lingens in the Stanford library (Perry 1977), which we discussed briefly in  section 1,  and the case of the lost hiker in the Desolation Wilderness (Perry 1979). They are worth noting because they are in some respects less odd and science-fictional than the case of the two gods, but we will not take them up in detail because their load-bearing structural features are the same.
