"Shanker presents a new and interesting interpretation of Wittgenstein's philosophy of mathematics. I am persuaded that he is reading Wittgenstein basically correctly. Wittgenstein's views seem even more radical and bizarre on Shanker's reading than they did before. Shanker also argues for the correctness of Wittgenstein's position, but I find that completely implausible. Nevertheless, his argument is vigorous and shows an excellent, up-to-date grasp of the relevant literature." — Nicholas D. Goodman
