In this volume two purposes have been fulfilled: it applies to the problems of human suffering a practical, spiritual philosophy of the Inner Life, and it contains a discriminative exposition of the rational principles which underlie the mental healing movement. With these ends in view, it was thought best to revise and incorporate portions of the The Philosophy of P. P. Quimby and Methods and Problems of Spiritual Healing. The book contains valuable quotations from the manuscripts of Julius A. Dresser and an exposition of the teachings in which be and other pioneers restated the theories of Mr. Quimby. There are abundant data for all who wish to settle the question of the real vs. the alleged founder of the movement, although the book is not at all controversial. As a whole, the book contains the first adequate statement of the parent doctrine, and it will especially aid those who wish to estimate the permanent worth of mind-cure teachings.
