From Phineas Parkhust Quimby in the 1850s to Louise Hay, Marianne Williamson, Michael Beckwith, and thousands of others in the 2000s, the New Thought movement in the U.S. has produced a marvelous lineage of healers and teachers. In The Science of Mental Healing, Dr. Ruth L Mille introduces some of the leaders and explains how what they teach works, giving us a glimpse into their lives and teachings, along with the modern experimental and theoretical science that supports them, and helps us begin to practice some of their insights and methods.
