 Here it’s easy to see why the terminology of self-location is appealing—Lingens’ problem doesn’t seem to be ignorance about what the world is like. It’s ignorance about his own location within the world. (Another metaphor one finds in the literature: his problem isn’t that he doesn’t know how to draw the map of the world; it’s that he doesn’t know where to place the “you are here” arrow on that map.) In many respects, this is a helpful and clarifying way to think about the purported special category of belief that resists characterization in non-indexical terms: it’s belief about one’s particular location within the world.
