Followers of the New Thought movement of the early 20th century vehemently believed in the concept of "mind over matter," none moreso than William Walker Atkinson. In 1918, writing under the name Theron Q. Dumont, Atkinson argued that the nerves and ganglia of the solar plexus form a separate, "instinctive mind" that energizes and regulates the body's organs and emotions. Mixing Eastern ideas with Western pragmatism, Atkinson provides a series of breathing and mental exercises that link the "thinking mind" with the "abdominal brain" to help both control emotions and improve physical wellbeing. With an emphasis on practice over theory, this slim, absorbing work seems right at home in an era of holistic and alternative medicines. 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.
