One of the really remarkable facts of modern life is the disinclination to accept at apparent value the scientific and other evidence there is to prove that consciousness persists after the death of the physical body. There is in existence a large amount of such evidence and much of it is offered by scientists of the highest standing; and yet the average man continues to speak of the subject as though nothing about it had yet been definitely learned. It is the tendency of the human mind to adjust itself very slowly to the truth, as it is discovered. Sometimes a generation passes away between the discovery and the general acceptance of a great truth. When we recall the intense opposition to the introduction of steam-driven boats and vehicles, and the slowness with which the world settles down to any radical change in its methods of thinking, it will perhaps seem less remarkable that the truth about the life after bodily death has waited so long for general recognition. The evidence upon which a belief in the continuity of consciousness is based is of two kinds--that furnished by physical science and that furnished by psychic science. Together they make a very complete case. The printed evidence of the first division--physical science--is voluminous. In addition to that gathered by the Society for Psychical Research there are the researches and experiments by the scientists of England, France and Italy, among whom are Crookes, Lodge, Flammarion and Lombroso. Crookes was a pioneer in the work of studying the human consciousness and tracing its activities beyond the change called death. All of that keenness of intellect and great scientific knowledge, which has enabled him to make so many valuable discoveries and inventions, and has won for him world-wide fame, were brought to bear upon the subject, and for a period of four years he patiently investigated and experimented. Many illustrated articles prepared by him, fully describing his work, were published at the time in _The Journal of Science_ of which he was then the editor.
