In this volume, first published in 1921, Horatio Dresser compiles the writings of Phineas Quimby, the founder of the 19th-century New Age philosophy of New Thought. Quimby’s manuscripts were much sought-after, and it was only through his personal friendship with Quimby and his family that Dresser was able to obtain them. Phineas Quimby developed his own religion based on Christianity and following the example of Jesus. He began with healing the mentally and physically ill and offering the healed the chance to read his manuscripts if they desired. In this book Quimby’s rules for healing with the mind are revealed. Those interested in the history New Thought, Christian sects, mesmerism, and the power of the mind over the body will want to study these primary sources. American New Thought author HORATIO WILLIS DRESSER (1866-1954) wrote a number of books about mental health and spirituality including The Perfect Whole (1896) and In Search of a Soul (1897). Later in life, he left the New Thought movement and went to work at Harvard University, where he wrote about philosophy. Because of this abandonment of his earlier work, his writings are often forgotten today.
