Some generic generalizations have both a descriptive and a normative reading. The generic sentence “Philosophers care about the truth”, for instance, can be read as describing what philosophers in fact care about, but can also be read as prescribing philosophers to care about the truth. On Leslie’s account, this generic sentence has two readings due to the polysemy of the kind term “philosopher”. In this paper, I first argue against this polysemy account of descriptive/normative generics. In response, a contextualist semantic (...) theory for generic sentences is introduced. Based on this theory, I argue that descriptive/normative generics are contextually underspecified. (shrink)
