Abstract

This article describes some historical precursors that led to William James’s participation in the Hibbert Lectures and his subsequent publication of A Pluralistic Universe. William James viewed the monism–pluralism issue as the greatest issue the human mind can frame, and he returned to this issue again and again in his psychological and philosophical works. The Hibbert Lectures afforded an opportunity to explore the problem of monism and pluralism in a broadly religious or spiritual context. We describe James’s logical and experiential attacks on monistic thinkers, his seemingly paradoxical introduction of Gustav Fechner’s panpsychism to English-speaking philosophers, and his spirited defense of pluralism. We conclude by discussing the relevance of James’s pluralism for current questions of unification in psychology
