Principles of Psychology, The (2 v. 1890).

a treatise by <IR> WILLIAM JAMES </IR> . A biologist and physiologist as well as a philosopher, James was particularly qualified to establish psychology as a science in its own right, rather than as a subdivision of philosophy. The Principles of Psychology represents the achievements of psychology at the end of the 19th century and asserts its right to be considered an independent science, based on the physiology of the nervous system. The primary literary significance of the Principles lies in the chapter on the "stream of thought," which was a germinal factor in the development of the <IR> STREAM OF CONSCIOUSNESS </IR> technique of writing.
