"How to speak with the dead" by Sciens is a practical handbook written in the early 20th century. It argues, in a coolly “scientific” tone, that human souls survive bodily death and that disciplined methods can enable communication with them. Framed against spiritualism’s showmanship, it promises evidence, procedures, and cautions for rational readers seeking results rather than spectacle. The opening of the handbook lays out its plan: practical instructions later, but first a case for survival and communication that claims impartiality and “hard facts.” The Preface defends investigation on utilitarian grounds, even asserting that spirit-derived insights into gravitation and levitation could transform aviation, citing Crookes and Crawford and alluding to Edison’s rumored “spook factory.” Chapter I argues that religion and science alike imply survival, distinguishing soul from body via examples (trance, paralysis, sleep), and offers Crawford’s lab weighings as proof of intelligent, discarnate agency, buttressed by Lodge’s “Raymond” and S.P.R. work, plus a moral critique of strict materialism. Chapter II separates impersonal, organizing “life” from the personal, conscious, moral “soul,” listing sharp contrasts and clarifying that “death” ends bodily life but not soul-existence. Chapter III introduces telepathy and “tele-mnemoniky” (memory-reading), proposing an ether-like medium to explain thought and memory transfer, including apparent “thought-reading.” Chapter IV claims many spirits linger near Earth, questions distant spirit-spheres, advances reincarnation as a tidy hypothesis, describes spirit “bodies” without race or sex, and notes that character can shift once freed from bodily limits, with few signs of outright devils and some unreliability in statements. Chapter V begins by defining mediums as rare but real, often amateurs, tools rather than authors of messages, warns about fraud without dismissing the genuine, and cautions that a medium’s mind can color communications, casting doubt on theatrical “controls.” (This is an automatically generated summary.)
