Preliminary Report of the Commission Appointed by the University of Pennsylvania to Investigate Modern Spiritualism

The report opens with a reflective foreword that places the commission’s work at the crossroads of emerging psychology and the still‑vibrant world of Spiritualism. Formed at the request of a late benefactor, a small group of scholars from the University of Pennsylvania set out to examine the claims of mediums, slate‑writing, sealed letters and materializations that had captured public imagination in the late nineteenth and early twentieth centuries. Their aim is modest yet ambitious: to separate genuine phenomena from the tricks and superstitions that have long surrounded them.

The investigators, most of whom balance the study with full‑time duties, bring a measured, scientific rigor to a subject often cloaked in sentiment and controversy. Their findings, presented with a wry, satirical tone, provoked fierce backlash from spiritualist publications, highlighting the deep cultural divide between believers seeking comfort and skeptics demanding proof. The report offers a glimpse into that heated dialogue, preserving both the earnest curiosity of its authors and the passionate defense of the movement they scrutinized.

Readers will discover a snapshot of an era where faith, grief, and the quest for empirical truth collided, inviting them to weigh the evidence and form their own conclusions about the mysteries that fascinated a generation.
