This book explores Wittgenstein's long engagement with the work of the pragmatist William James. In contrast to previous discussions, Russell Goodman argues that James exerted a distinctive and pervasive positive influence on Wittgenstein's thought. He shows that both share commitments to anti-foundationalism, to the description of the concrete details of human experience, and to the priority of practice over intellect. Considering in detail what Wittgenstein learnt from his reading of William James, Goodman provides considerable evidence for Wittgenstein's claim that he is saying "something that sounds like pragmatism."
