Principles of Psychology (Volume 1 of 2)

A superbly thorough guide to psychology, William James' thesis successfully summarizes the tenets of the science in the early 20th century - this edition contains the vital notes and illustrations.
Appearing in 1890, The Principles of Psychology was a landmark text which established psychology as a serious scientific discipline. William James' compiled a convincing, lengthy and broad thesis, devoting detail and vigorous analysis in every chapter. The text's comprehensiveness and superb presentation played a pivotal role in bringing the science of mental health closer toward the scholarly mainstream.

The entire book is set out intuitively: there are two volumes, each of which has a certain number of chapters. While some chapters have sub-sections, James is careful not to make his textbook dry or convoluted in organisation.
