'This book presents abundant evidence for the pluralism in William James's understanding of the human thought and action. It documents James's close reading of psychological and philosophical research and theorizing and shows that he intuited the directions of later psychological science. Holding this book's insights alongside the work of contemporary psychology offers potential to 'stretch the boundaries of psychological science.' For James's deliberate explorations, Araujo and Osbeck are sure-footed and intelligent guides.' Paul Croce, Stetson University
