“The higher attainment,” says Dr. John Hamlin Davey, “of occult knowledge and power, the development of intuition, the psychometric sense, clairvoyant vision, inner hearing, etc., etc., thus reached, so open the avenues to a higher education, and enlarge the boundaries of human consciousness and activity, as to fairly dwarf into insignificance the achievements of external science.” Clairvoyance is as old as mankind, but the exhibition of clairvoyance, induced by mesmeric processes, was first announced by Puysegeur, a favourite pupil of Mesmer, in 1784. Since that time to the present not only have remarkable cases of clairvoyance cropped up, but there have been few mesmerists of any experience who have not had numerous cases under observation. Clairvoyance converted Dr. John Elliotson, F.R.S., one of the most scientific of British physicians, from extreme materialistic views to that of belief in soul and immortality. The same may be said of the late Dr. Ashburner, who was one of the Queen’s physicians. Dr. Georget, author of “Physiology of the Nervous System,”--who was at one time opposed to a belief in the existence of a transcendental state in man,--found upon examination of the facts and incidents of artificial somnambulism, that _his materialism must go_. In his last will and testament, referring to the above-mentioned work, he says:--“This work had scarcely appeared, when renewed meditations on a very extraordinary phenomenon, somnambulism, no longer permitted me to entertain doubts of the existence within us, and external to us, of an intelligent principle, altogether different from material existences; in a word, of the soul and God. With respect to this I have a profound conviction, founded upon facts which I believe to be incontestable.” Dr. Georget directed this change of opinion should have full publicity after his death.
