In Between Logic and the World, Bernhard Nickel distinguishes two tasks in understanding generics. 

And he thinks he is Griceian, or a Griceian, strictly.

The first task is to give a compositional semantics—ideally, one that coheres with independent theories of semantic phenomena like plurality and conjunction. Between Logic and the World undoubtedly makes a substantial contribution to this task. Nickel argues that his proposed semantics allows us to understand logically complex generics as well as generics containing gradable terms. The second task is to give a theory of metaphysical genericity. Nickel explains this with an analogy. Just as there is a metaphysical phenomenon underlying the meaning of modals—modality—there is one underlying the meaning of generics—genericity. Just as a semantic theory of modals and a metaphysical theory of modality will constrain and illuminate each other, so too will a semantic theory of generics and a metaphysical theory of genericity.Nickel’s ability to thoughtfully connect issues...
