Scholars have long wondered how the small religious movement of New Thought has come to have such a profound and diffuse impact on American culture. This paper argues that Alcoholics Anonymous may have served as one mass dispersal mechanism for New Thought ideas. My work demonstrates that the founding members of AA were influenced by the popular Depression-era New Thought teacher Emmet Fox, in particular his book The Sermon on the Mount: The Key to Success in Life. A comparison of Fox's Sermon and AA's foundational text, Alcoholics Anonymous (or the Big Book, as it is known to members), provides evidence of this influence and suggests one means by which many Americans have been introduced to New Thought ideas.
