_The author has had sittings with many famous mediums of this country and Europe, but has seen little to convince him of the fact of spirit communication. The slate tests and so-called materializations have invariably been frauds. Some experiments along the line of automatic writing and psychometry, however, have demonstrated to the writer the truth of telepathy or thought-transference. The theory of telepathy explains many of the marvels ascribed to spirit intervention in things mundane._ _In this work the author has endeavored to give an accurate account of the lives and adventures of celebrated mediums and occultists, which will prove of interest to the reader. The rise and growth of the Theosophical cult in this country and Europe is of historical interest. Theosophy pretends to a deeper metaphysics than Spiritualism, and numbers its adherents by the thousands; it is, therefore, intensely interesting to study it in its origin, its founder and its present leaders._ _THE AUTHOR._ HOURS WITH THE GHOSTS. INTRODUCTORY ARGUMENT. "If a man die, shall he live again?"--this is the question of the ages, the Sphinx riddle that Humanity has been trying to solve since time began. The great minds of antiquity, Socrates, Pythagoras, Plato and Aristotle were firm in their belief in the immortality of the soul. The writings of Plato are luminous on the subject. The Mysteries of Isis and Osiris, as practiced in Egypt, and those of Eleusis, in Greece, taught the doctrine of the immortality of the individual being. The Divine Master of Arcane knowledge, Christ, proclaimed the same. In latter times, we have had such metaphysical and scientific thinkers as Leibnitz, Fichte, Schelling, Hegel and Schleiermacher advocating individual existence beyond the grave.
