How the term "Spiritism" came about
Allan Kardec was a translator, philosopher, author, and educator who was fascinated by psychic and mediumistic phenomena. Initially, he was a skeptic who felt that all inexplicable phenomena could be explained by nature, science, hallucination, or deception.
Following that, he established a slew of scientific inquiries to research, categorize, and investigate unexplained occurrences such as séances. Allan Kardec invented the name ''Spiritism'' during his investigations to encompass the notions, ideas, and hypotheses that emerged from his discoveries. In 1862, he released Spiritism in its Simplest Expression, a summary of Spiritism's philosophies.
Although Allan Kardec believed that nature, science, or fraud could explain the majority of psychic events recorded during his investigation, he believed that these explanations did not account for all psychic occurrences. Over time, he grew to assume that some unexplained phenomena were generated by aware spiritual powers, building on spiritualist ideas.
Allan Kardec proposed that these unexplained phenomena could be explained by some intelligent force with agency, such as spirits, souls, or other noncorporeal beings with the ability to alter the physical world.
