In this paper I argue, first, that the only difference between Epistemicism and Nihilism about vagueness is semantic rather than ontological, and second, that once it is clear what the difference between these views is, Nihilism is a much more plausible view of vagueness than Epistemicism. Given the current popularity of certain epistemicist views (most notably, Williamson’s), this result is, I think, of interest.

According to the view I christen sharpism, when Joe says to his daughter in a perfectly ordinary context ‘The Earth is super-duper old’, his claim has an incredibly discriminating truth condition: although it’s true if the Earth is over 347,342,343 years, 2 days, and 17 nanoseconds old, if the Earth is even a nanosecond younger then his claim has some status other than “just plain true”—but we leave open what that new status might be: false, indeterminate, indeterminately indeterminate, meaningless, just (...) under 100% true, or whatnot. The material point is that the claim changes in truth status (“alethic status”) with a nanosecond change in the Earth’s age. The sharp cutoff might not be a cutoff separating the true from the false, but it is a sharp alethic cutoff nonetheless. It has this sensitive truth condition even though Joe has never made any relevant linguistic stipulations and doesn’t even know what a nanosecond is. Another example: when I say to a visiting speaker, ‘The auditorium where you’ll give your lecture is a short walk from here’, my claim is true if the auditorium is no more than 123 meters, 6 centimeters, and 16 nanometers away. Hence, if it turns out that we were 123 meters, 6 centimeters, and 17 nanometers away from the auditorium, my claim had some status other than true. (shrink)

Unger claims that we can block sorites arguments for the conclusion that there are no ordinary things only by invoking some kind of miracle, but no such miracle is needed if we reject the principle that every statement has a truth value. Wheeler's argument for the nonexistence of ordinary things depends on the assumptions that if ordinary things exist, they comprise real kinds, and that if ordinary predicates really apply to things, the predicates refer to real properties. If we accept (...) Wheeler's criteria for the reality of kinds and properties, we have no good reason to accept these assumptions. (shrink)
