Allan Kardec founded the entire Spiritism religion after interrogating tapping tables in Paris

From moving tables to a system of belief

In 1850s Paris, “turning tables” were a fashionable parlour pastime: participants gathered around a table that seemed to tilt, turn, or knock. Some groups treated the movements as messages from spirits. To make the knocks intelligible, a questioner might assign letters to a sequence of taps, turning an apparent movement into a yes-or-no answer or a spelled-out reply.

Allan Kardec—the pen name of French educator Hippolyte Léon Denizard Rivail—approached these sessions as more than entertainment. He posed questions about the nature of spirits, human life, and moral conduct, then collected answers conveyed through mediums, people believed to be able to communicate with spirits. The table was the doorway; the larger project was to organize what participants took to be a body of teachings.

How the answers became Spiritism

Kardec compared and arranged the reported responses into a coherent philosophy rather than presenting each séance as an isolated marvel. In 1857, he published The Spirits’ Book, setting out teachings that included the existence of spirits, communication with them, reincarnation, and continuing moral development. The book helped give Spiritism a recognizable structure and identity.

That process also helps explain why the movement outlasted the table-turning craze. The physical phenomenon drew attention, but the proposed answers addressed enduring questions: why people suffer, whether life continues after death, and how moral choices shape a person’s progress. Readers could encounter those ideas as a connected system, not merely as reports of mysterious knocks.

A lasting legacy

Spiritism spread beyond France and became especially popular in Brazil, where it developed a substantial community and institutional presence. Kardec’s role was not simply to popularize moving tables; it was to turn séance reports into a teachable religious philosophy. For followers, that distinction is central: the taps were evidence of contact, while the organized teachings gave that contact meaning.
