In the early 1850s, a new philosophical, social, and political movement evolved from the Freethought tradition of Thomas Paine, Richard Carlile, Robert Owen, and the radical periodical press. The movement was called “Secularism.”1 Its founder was George Jacob Holyoake (1817–1906) (Grugel 1976, 2–3).2 Holyoake was a former apprentice whitesmith turned Owenite social missionary, “moral force” Chartist, and radical editor and publisher. Given his early exposure to Owenism and Chartism,3 Holyoake had become a Freethinker. With his involve- ment in Freethought publishing, he became a moral convert to atheism. However, his experiences with virulent proponents of atheism or infidelity and the hostile reactions to them on the part of the state, church, and press induced him to develop in 1851–1852 the new creed and movement he called Secularism.
