A product of the "spiritual hothouse" of the Second Great Awakening, Spiritualism became the fastest growing religion in the nation during the 1850s, and one of the principal responses to the widespread perception that American society was descending into atomistic particularity.
From the beginning, however, Spiritualist political and social expression was far more diverse than has previously been recognized, encompassing distinctive proslavery and antiegalitarian strains, and in the wake of racial and political adjustments following the Civil War, the movement began to fracture. Cox traces the eventual dissolution of Spiritualism through the contradictions of its various regional and racial factions and through their increasingly circumscribed responses to a changing world. In the end, he concludes, the history of Spiritualism was written in the limits of sympathy, and not its limitless potential.
