““More daring, though, was Jung’s uninhibited interest in spiritualism, which by this time had become a controversial topic on both sides of the Atlantic, ever since 1848, when the Fox sisters of Hydesville, New York, discovered they could communicate with the spirit of a dead man. Soon after this, mediums, table turning, floating tambourines, ectoplasmic limbs, and a variety of other otherworldly phenomena became the focus of an international craze; the flood of disincarnate appearances led one investigator to speak of an “invasion of the spirit people.”7 Colorful characters like the Russian medium and mystic Helena Petrovna Blavatsky were involved, but also scientists and philosophers like William James, Oliver Lodge, William Crookes, and Frederick Myers. It is difficult for us today to realize that at the time, many of the most famous men and women in the world were involved in spiritualism, to one degree or another. Thomas Edison, for example, who joined Blavatsky’s Theosophical Society, hoped to be able to record spirits on his “Spirit Phone.” Yet, for all this, the reductionist thought that dominates the academic world today was already securely in place, and Jung was risking his future career by openly advocating the unbiased study of the paranormal.””
