Working under an array of pseudonyms and pen names, author and thinker William Walker Atkinson produced a prodigious body of influential work during his lifetime. Among other accomplishments, Atkinson is credited with developing the "New Thought" movement that has come back into vogue in recent years with the publication of The Secret. In this volume, Atkinson makes a compelling case for the need for rational thought and reasoning, and sets forth guidelines and examples to help readers incorporate these principles into their lives.
