The importance of psychic phenomena and its intense interest lie in the fact that psychical research hints at a possible solution, by means of the same methods which science has been accustomed to use in the physical world, of the great problem of man's future destiny, of an answer to the question asked by Job thousands of years ago, "If a man die, shall he live again?" and which has been repeated in vain by every generation of men who have since inhabited the earth. Prof. Flournoy approaches the problems of the psychic world in regard to the strange phenomena manifested by Mlle. Helene Smith. No fact has been regarded by him as too trivial to escape his keen, careful scrutiny from a psychological point of view.
