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

by Thomson Jay Hudson

"The Law of Psychic Phenomena" by Thomson Jay Hudson is a scientific publication written in the late 19th century. The book seeks to establish a comprehensive working hypothesis to analyze and classify various psychic phenomena, including hypnotism, spiritism, and mental therapeutics. Hudson aims to bridge the gaps in psychological science by proposing that many seemingly disparate psychic manifestations are connected through a general principle that can be understood and studied systematically. The opening of the work lays the groundwork for this ambitious project by articulating the necessity for a unifying hypothesis in psychology, akin to those in other scientific domains like physics and chemistry. Hudson argues that without such a framework, psychological phenomena remain chaotic and misunderstood. He quickly introduces the concept of duality in human mental processes, positing the existence of an "objective mind" that interacts with the physical world through the senses, and a "subjective mind" that operates outside of these constraints, particularly when in states of hypnosis. This duality is central to understanding the book’s deeper exploration of how the human mind navigates and comprehends psychic phenomena.
