Before "New Age" there was "New Thought," a philosophy that sought God through metaphysics and was wildly popular in the late 19th and early 20th centuries. As perhaps the movement's most vocal proponent, William Walker Atkinson-here writing as Theron Q. Dumont-believed above all in the power of the mind, especially as it affected the body's ability to heal. Elaborating on the idea that the corporeal mind, made up of a body's cells and organs, is subject to mental suggestion, Dumont provides detailed lessons on how to use thought to promote the body's natural healing abilities. Unlike many occult- or religion-based approaches, the author gives equal attention to the biological processes and functions of the body, something he believed to be crucial to proper visualization. More than just an entertaining time capsule, Mental Therapeutics is a set of principles and healing techniques that can easily coexist alongside today's medical advances. American writer WILLIAM WALKER ATKINSON (1862-1932) was editor of the popular magazine New Thought from 1901 to 1905, and editor of the journal Advanced Thought from 1916 to 1919. He authored dozens of New Thought books under a variety of pseudonyms, including Yogi Ramacharaka, Theodore Sheldon and Theron Q. Dumont. His other works include Character Reading and The Power of Concentration.
