The Law of Psychic Phenomena: A Working Hypothesis for the Systematic Study of Hypnotism, Spiritism, Mental Therapeutics, Etc.

Published in 1904, this audacious work attempts something unprecedented: a unified theory of psychic phenomena that would bring psychology into the ranks of the exact sciences. Hudson argues that hypnotism, spiritism, mental therapeutics, genius, and even madness are not isolated abnormalities but interconnected manifestations of a single underlying principle. He introduces his central concept of mental duality: the "objective mind" that perceives through the physical senses, and the "objective mind" that operates beyond them, particularly accessible through hypnotic states. This framework was revolutionary, attempting to drag the study of consciousness out of the realm of superstition and into systematic scientific inquiry at a time when the Society for Psychical Research was actively documenting hauntings, telepathy, and mediumship. Hudson's prose is remarkably prescient, anticipating concepts that would later emerge in psychoanalysis and cognitive psychology. The book remains a fascinating artifact of early psychological inquiry, revealing both the profound ambition and the methodological limitations of turn-of-the-century mind science. For readers interested in the intellectual history of psychology, the origins of parapsychology, or the forgotten ancestors of modern consciousness studies, this offers a window into a moment when the boundaries between science and spiritualism had not yet been drawn.
