The author marshals contemporary reports and investigations to argue that mediumistic phenomena warrant serious scientific scrutiny. He reviews accumulated testimony and experimental accounts, distinguishes physical from mental manifestations, confronts charges of imposture, and challenges strictly materialist explanations as incomplete. Advocating careful controls and impartial inquiry, he contends that accepting these phenomena would affect philosophical and religious understandings of consciousness and human nature. The essay seeks to persuade skeptical readers by weighing the cumulative evidence and urging continued, methodical investigation rather than wholesale dismissal.
