Between 1866 and 1870, Eddy boarded at the home of Brene Paine Clark who was interested in Spiritualism. Seances were often conducted there, but Eddy and Clark engaged in vigorous, good-natured arguments about them. Eddy's arguments against Spiritualism convinced at least one other who was there at the time—Hiram Crafts—that "her science was far superior to spirit teachings." Clark's son George tried to convince Eddy to take up Spiritualism, but he said that she abhorred the idea. According to Cather and Milmine, Richard Hazeltine attended seances at Clark's home, and Eddy had acted as a trance medium, claiming to channel the spirits of the Apostles.
