The Dangers of Spiritualism is a book by author John Godfrey Raupert (1858-1929), first published in 1901 and again published in 1920 in London (fifth edition). Rauperts wanted to provide an account of personal experiences with the "spirit world" and a warning against the dangers of investigating it. He hoped to prove the existence of spiritualism using scientific methodology. The methods he most often uses are spirit photography and automatic writing using a planchette. Given the time the book was published, this view was not regarded as abnormal. The case studies described in the book are collected by the author and consist mostly of his experiences and reports he received. Source: Wikipedia (en)
