Note 164 — Chapter XVI
Reading edition
The explanation suggested in the text for the physical phenomena of Spiritualism is worked out in some detail by Von Hartmann, the philosopher of the unconscious, in a little treatise on Spiritism, which has been translated into English by "C.C.M.," 1885. But Von Hartmann believes that some of the phenomena are produced by a hypothetical nerve-force under the direction of the somnambulic self of the medium—a prodigality of hypotheses which in the circumstances is surely superfluous.
