On the Threshold of the Unseen : An Examination of the Phenomena of Spiritualism and of the Evidence of Survival after Death

Omtale

First published in 1917, this book contains a scientific investigation into psychical experiences including levitation, telepathy, automatic writing and clairvoyance. Determined to prove the existence of such phenomena, scientist Sir William Barrett (1844–1925) provides substantial evidence in the hope that spiritualist activities will become accepted by the scientific establishment.
