This new edition of William James’s 1909 classic, A Pluralistic Universe reproduces the original text, only modernizing the spelling. The books has been annotated throughout to clarify James’s points of reference and discussion. There is a new, fuller index, a brief chronology of James’s life, and a new bibliography-chiefly based on James’s own references. The editor, H.G. Callaway, has included a new Introduction which elucidates the legacy of Jamesian pluralism to survey some related questions of contemporary American society. A Pluralistic Universe was the last major book James published during his life time. It is a substantial philosophical work, devoted to a thorough-going criticism of Hegelian monism and Absolutism-and the exploration of philosophical and social-theological alternatives. Our world of some one hundred years on is much the better for James’s contributions; and understanding James’s pluralism deeply contributes even now to America’s self-understanding. At present, we are more certain that American is, and is best, a pluralistic society, than we are of what particular forms our pluralism should take. Keeping an eye out for social interpretations of Jamesian pluralism, this new philosophical reading casts light on our twenty-first century alternatives by reference to prior American experience and developments.
