"The Proletarian," the Socialist paper of Detroit, in its April, 1919, edition tells us that "Socialism is not a religion, it explains the causes and fallacies underlying all religions."
In the "International Socialist Review," August, 1908, a notable confession is made relative to religion:
"Religion spells death to Socialism, just as Socialism to religion. The moment Socialism turns into a religion it loses all its progressiveness, it ossifies and turns into a superstition of fanatics, who never forget and never learn anything. Socialism is essentially, although not apparently, a free-thought movement. The thinking Socialists are all free-thinkers."
In the "International Socialist Review" not only are there many articles and editorials attacking religion, but also many advertisements of atheistical and anti-religious books. For instance, in the February, 1912, edition, among the many works advertised on page 512 the following are listed under the heading, "Free-Thought Pamphlets":
/P "Holy Smoke in Holy Land. Myth of the Great Deluge. Revelation Under the Microscope of Evolution. Chas. Darwin, What He Accomplished. Jehovah Interviewed. Church and State--by Jefferson. Mistakes of Moses--by Ingersoll. Ingersolia: Gems from R. G. Ingersoll. Age of Reason--by Thos. Paine. Ingersoll--44 Lectures. Ingersoll's Famous Speeches." P/
In the April, 1912, edition of the "International Socialist Review" the subsequent additions are made to the advertisements already mentioned:
