Joseph Maxwell on mediumistic personifications.

The study of mediumship received much impetus from the work of psychical researchers. This included ideas about the phenomena of personation, or changes in attitudes, dispositions and behaviours shown by some mediums that supposedly indicated discarnate action. The aim of this Classic Text is to reprint passages about this topic from the writings of French psychical researcher Joseph Maxwell (1858-1938), which were part of the contributions of some psychical researchers to reconceptualize the manifestations in psychological terms. Maxwell suggested these changes in mediums were a production of their subconscious mind. His ideas are a reflection of previous theorization about secondary personalities and a particular example of the contributions of psychical researchers to understand the psychology of mediumship.
