Initially published in New York alternately with D.M. Bennett's The Truth Seeker; beginning October 1874 it was published from Chicago with Wilson listed as editor and proprietor. Bennett who had been hired by Wilson to publish the journal announced his withdrawal after four issues, citing "good and sufficient reasons," probably financial. The journal was originally started as a radical ("free love") counter to the Religio-Philosophical Journal, using a stolen copy of the RPJ's subscription list to send out sample copies. A large part of the content was devoted to Wilson's disputes with S.S. Jones over free love and claims of unpaid money. (Wilson finally sued Jones, to no avail, for having destroyed his lecturing business with his slanders.) The character of Ebenezer Vespasian Wilson (1818-1880) and his faction in spiritualism (Victoria C. Woodhull, Moses Hull, W.F. Jamieson, Warren Chase, et al.) is colorfully indicated by Col. Bundy's description of a spiritualist/free love conference organized by Wilson in Chicago in 1874 as "Bummers and Bawds," and by S.S. Jones's "A Sickening Spectacle," Religio-Philosophical Journal 16/2 (March 28, 1874): 1. In its final issues, the journal was still staunchly supporting Victoria C. Woodhull. H.P. Blavatsky declared (one of many contradictory statements on the subject) that a seance she attended with Wilson in 1873 or 1874 (he was a seer, psychometrician and reader of sealed letters) was the first she had ever seen.
