 Of course, vagueness and indeterminacy are problems for most theories of masses, so it could be unfair to overstress this point, and it is not at all clear that the pluralist can’t augment her account with standard logics of vagueness or employ analogues to set-theoretic non-well-foundedness moves. (See Chierchia 2010 for an examination of vagueness and its relation to mass nouns, and a development of a plural approach, which can be found in many other articles, e.g. Chierchia 1998a). Given the many salutary components of plural logic in relation to mass expressions, this remains a promising area of inquiry.
