Is the world of appearances the real world? Are there facts that exist independently of our minds? Are there vague objects? Russell on Metaphysics brings together for the first time a comprehensive selection of Russell's writing on metaphysics in one volume. Russell's major and lasting contribution to metaphysics has been hugely influential and his insights have led to the establishment of analytic philosophy as a dominant stream in philosophy. Stephen Mumford chronicles the metaphysical nature of these insights through accessible introductions to the texts, setting them in context and understanding their continued importance. Russell on Metaphysics is both a valuable introduction to Bertrand Russell as a metaphysician, and an introduction to analytic philosophy and its history.
