A few extracts from _How to Speak with the Dead_[36] will illustrate these pernicious attempts. [Footnote 36: By Sciens: Kegan Paul, Trench, Truebner & Co.] (Page 88) 'By sitting in some place quite alone and free from interruption, and by adopting a mental attitude of passive receptivity and expectancy, the soul becomes ready to perceive and be affected by any spirits that may be in its vicinity and that may attempt to open up communications.... The manifestations ... may vary from thought-suggestion to positive physical phenomena ... such as the hearing of a voice or even the visual appearance of some supernormal object. All depends upon whether the sitter is or is not susceptible to psychical influence, and also upon whether the locality or the sitter personally is or is not haunted.' Then (page 91) when the Dissociation has developed:-- 'In cases where the sitter is markedly "psychic" it frequently happens that normal control over the body is lost. A condition of trance supervenes, and while this continues the spirit--which may be either a "second personality" or a soul from the outside--that has gained the upper hand makes use to a greater or less extent of the brain and other organs subject to its mastery. The hand may write: the mouth may speak: the whole body may be engaged in some impersonation; and all this may take place beyond the scope of the sitter's normal consciousness.' Lest the hysterical dissociation is not yet enough developed, the victim receives, on page 98, another thrust along the road to disease:-- 'If it be found on trial that psychic powers exist to an appreciable extent it may be taken for granted that they are capable of very great increase by persevering effort and systematic employment.' A warning is both given and stultified on page 107:-- 'Self-deception and the imaginations bred of wishes and emotions are to be guarded against;' ... 'in solitary Expectancy fraud and trickery are completely absent, and all manifestations are matters of the most simple personal observation, the accuracy of which can be confirmed--as in an ordinary scientific laboratory--by the test of repetition.'
