Thesis advisor: Rosemarie Bodenheimer / By focusing on the predominance of semi-conscious and unconscious states in both nineteenth-century British literature and psychology, this dissertation outlines the recognizable and multi-faceted relation existing between literature and psychology. Besides their obvious prevalence in sensation novels later in the period, these states, which I call ecstatic states, appeared in many of the most prominent, canonical novels of the nineteenth century. Prominent Victorian psychologists, such as Robert MacNish, John Abercrombie, James Cowles Prichard, and Forbes Winslow among others, connected ecstatic states, including fiction reading, to insanity, since these states exhibited an underlying component of self-loss in which the boundaries of the conscious self--time, will, and identity--dissolved. They were a troubling, yet common phenomenon of the mind that preoccupied the entire spectrum of middle class Victorian intellectual life--businessmen, novelists, literary critics, and psychologists--and these states are still fascinating neuroscientists today. This study shows how the Victorian medical practice of moral management sought to control these states by calling for the regulation and often the confinement of the imagination. What began as a method used solely in the insane asylum came to undergird much of Victorian life, including the many hostile reactions to the addictive and class-leveling powers of the novel. My dissertation emphasizes how certain Victorian novelists not only took up the role of psychologists themselves but also resisted and revised accepted psychology within their novels. Charlotte Brontë, Charles Dickens, and George Eliot reacted in distinctive ways against the oppressive tenets of moral management. My readings of the novels Jane Eyre, Villette, Hard Times, Our Mutual Friend, The Mill on the Floss, and Romola show how it is the unrelenting regulation of the imagination that creates the various forms of mania and becomes ultimately devastating to the self. For these novelists, the dismantling of conscious thought and will, so alarming to the advocates of moral management, formed the crux of personal growth, moral choice, and ethical responsiveness. / Thesis (PhD) — Boston College, 2013. / Submitted to: Boston College.
