"For the psychologist, standard reading, to all readers, a classic of interpretation." —  Psychiatric Quarterly This is the first inexpensive edition of the complete Long Course in Principles of Psychology , one of the great classics of modern Western literature and science and the source of the ripest thoughts of America’s most important philosopher. As such, it should not be confused with the many abridgements that omit key sections. The book presents lucid descriptions of human mental activity, with detailed considerations of the stream of thought, consciousness, time perception, memory, imagination, emotions, reason, abnormal phenomena, and similar topics. In its course it takes into account the work of Berkeley, Binet, Bradley, Darwin, Descartes, Fechner, Galton, Green, Helmholtz, Herbart, Hume, Janet, Kant, Lange, Lotze, Locke, Mill, Royce, Schopenhauer, Spinoza, Wundt, and scores of others. It examines contrasting interpretations of mental phenomena, treating introspective analysis, philosophical interpretations, and experimental research. Although the book originally appeared nearly 75 years ago, it remains unsurpassed today as a brilliantly written survey of William James’ timeless view of psychology. "Rereading James brings a sense of perspective and even a little humility to our regard for more modern achievements." —  Journal of Consulting Psychology The Principles of Psychology, Vol. 1
