Penn Researchers Examine History, Beliefs and Rituals Tied to Ghosts: “…Justin McDaniel, professor and chair of the religious studies department at Penn, is director of the Penn Ghost Project, a Faculty Working Group of the School of Arts and Sciences. Formed last spring, the group is comprised of faculty from literature, art history, nursing, archaeology, religious studies, the history and sociology of science and medicine. ‘Either we’re all crazy,’ McDaniel says, 'or ghosts are a part of human phenomena and have been a mass phenomenon for a long, long time.'”
