The actual origin of the phantoms of the spirit-world is to be found in the lawless and luxuriant fancy of primeval man. The creatures of this fancy have been perpetuated throughout all time, unto our own day, by that passionate yearning in men for continued life and love, which is ineradicable in our nature. Men will not, they can not, accept the doubt which plunges an eternal future into eternal darkness, and separates them for ever from the creatures of their love. Hence, when the remorseless fact of Death removes those creatures, they look, with a longing which is indescribably pathetic, into the Unknown where their beloved have gone, and strive to see them in their spirit-life.
