  Both of these Quinean views, his naturalism and his acceptance of something like metaphysics, correspond to very important developments within analytic philosophy over the past half-century. His influence has surely played a significant role here. (In the case of metaphysics, in particular, it is notable that two leading figures, Saul Kripke and David Lewis, were students of Quine’s.) For the most part, however, those Quinean doctrines have led to work to which Quine himself would be strongly opposed.
