There was much uncertainty about how voice related to body in the early eighteenth century, and this became a major subject of scientific and cultural interest. In Voices from Beyond, Scott Sanders provides an interdisciplinary and transnational study of eighteenth-century conceptions of the human voice. His book examines the diversity of thought about vocal materiality and its roles in philosophical and literary works from the period, uncovering representations of the voice that intertwine physiology with physics, music with moral philosophy, and literary description with performance.
Voices from Beyond focuses on the voice as it was constructed in French works, influenced by French vocal sciences as well as British literary and philosophical texts. It considers the writing of Jean-Jacques Rousseau, Denis Diderot, FranƧois Baculard d'Arnaud, and Jacques Cazotte in particular, and explores how their texts theorize, represent, and construct three interrelated vocal types: the sentimental, the vitalist, and the uncanny. These authors represented the human voice as an intersectional organ with implications for one's emotional disposition, physical health, cultural identity, gender, and sexuality. Sanders argues that while the conception of sentimental and vitalist voices was anchored to a physiological understanding of vocal organs, this paradoxically led to the development of a disembodied, uncanny voiceāone that could imitate the sounds of a good moral fiber while masking a monstrous physiology.
