Psychic Investigators examines British anthropology’s engagement with the modern spiritualist movement during the late Victorian era. Efram Sera-Shriar argues that debates over the existence of ghosts and psychical powers were at the center of anthropological discussions on human beliefs. He focuses on the importance of establishing credible witnesses of spirit and psychic phenomena in the writings of anthropologists such as Alfred Russel Wallace, Edward Burnett Tylor, Andrew Lang, and Edward Clodd. The book draws on major themes, such as the historical relationship between science and religion, the history of scientific observation, and the emergence of the subfield of anthropology of religion in the second half of the nineteenth century. For secularists such as Tylor and Clodd, spiritualism posed a major obstacle in establishing the legitimacy of the theory of animism: a core theoretical principle of anthropology founded in the belief of “primitive cultures” that spirits animated the world, and that this belief represented the foundation of all religious paradigms. What becomes clear through this nuanced examination of Victorian anthropology is that arguments involving spirits or psychic forces usually revolved around issues of evidence, or lack of it, rather than faith or beliefs or disbeliefs.

The specialization thesis—the idea that nineteenth-century science fragmented into separate forms of knowledge that led to the creation of modern disciplines—has played an integral role in the way historians have described the changing disciplinary map of nineteenth-century British science. This volume critically reevaluates this dominant narrative in the historiography. While new disciplines did emerge during the nineteenth century, the intellectual landscape was far muddier, and in many cases new forms of specialist knowledge continued to cross boundaries while integrating ideas from other areas of study. Through a history of Victorian interdisciplinarity, this volume offers a more complicated and innovative analysis of discipline formation. Harnessing the techniques of cultural and intellectual history, studies of visual culture, Victorian studies, and literary studies, contributors break out of subject-based silos, exposing the tension between the rhetorical push for specialization and the actual practice of knowledge sharing across disciplines during the nineteenth century.
