The Law of Psychic Phenomena A working hypothesis for the systematic study of hypnotism, spiritism, mental therapeutics, etc.

This work opens a thoughtful window onto the late‑Victorian surge of scientific curiosity about the mind’s hidden powers. The author argues that phenomena once relegated to the supernatural—hypnosis, spirit communication, trance states, and even bouts of genius or madness—share a common underlying principle that can be studied with the same rigor as physics or chemistry. By invoking the efforts of the London Society for Psychical Research and other leading investigators, the text sets the stage for a systematic mapping of the strange and the subtle.

Drawing on a wealth of documented cases rather than original experiments, the writer assembles a provisional hypothesis that seeks to unite these diverse experiences under one law. The discussion is grounded in the language of induction and careful classification, inviting listeners to follow the early scientific attempt to bring psychology into the realm of exact science. As the argument unfolds, the book balances respectful acknowledgment of past testimony with bold speculation, offering a fascinating glimpse into the quest to make the mysterious measurable.
