A measured critique of Spiritualism that surveys its modern revival, the social groups drawn to séances, and the practices claimed to communicate with the dead. The author analyzes mediumship and its alleged controlling spirits, table phenomena, automatic writing, and the character of purported messages, weighing their credibility and moral risks. The work also examines the responses of churches, the appeal to scientific authority, and the consequences for bereaved individuals and casual inquirers, combining historical overview with contemporary examples and arguments urging caution about uncritical engagement with spiritist claims.
