In December, 1901, William Walker Atkinson in assuming the editorship of the popular magazine New Thought, introduced himself to the readers of that periodical in a memorable article. That article contained a clear, ringing, forceful statement of his individual creed, than which nothing can afford a deeper insight into the character and inner self of the man whose name appears as author of this book. It is the crystallized expression of the world-principles, the truths, which his writings seek to illuminate? and in my opinion should be read by every student of his works, as the key to the philosophy he teaches.
