This chapter discusses James’s definition of psychology and the topics he covered in The Principles of Psychology. It also treats the criticism that has been aimed at his arrangement of chapters, along with his responses to that criticism. Also discussed and illustrated with direct quotations is the elegance of his writing and his use of effective examples and metaphors to support his major points. Mention is made, too, of his references to episodes in his own life, which humanized his text and helped readers empathize, understand, and believe what he was trying to convey.
