1924. In this exposition, the author summons to his aid the most eminent spiritistic authorities, subjecting their testimony to a keen analysis, and their phenomena and assumptions to a searching criticism. Blackmore proves that some of the phenomena are preternatural beyond all questions, and distinguishes between the frauds of spiritism that are deliberately done by the medium and those inspired by spirits of evil. Sample contents: revival of spiritism; spiritism, old and new; spiritism tainted in its origin; mediums; automatic writing; Ouija board and the preternatural; spurious phenomena; alleged genuine phenomena; theories of causation; theory of telepathy; identification of spirits; claims of spiritists unverified; spirits of spiritism, not the souls of the dead; and others.
