This is an outstanding book. It offers an extremely attractive response to standard forms of external world skepticism, and rich and illuminating readings of J.L. Austin, G.E. Moore, and Wittgenstein. The prose is clear and sparkling, the argumentation careful and compelling, and the discussion highly sophisticated without ever getting bogged down in unnecessary detail. It offers a clarion call to a certain way of approaching our subject, an approach that is both distinctive and yet deeply familiar: a return to the convictions and subtleties of real life. * Adam Leite, Indiana University, Bloomington *
