Communism and Socialism.—Communism is a doctrine which would abolish individual rights, including the ownership of property. It began in England and France, but has never made any great progress. Socialism is allied to Communism, but is a milder form. It does not suggest the abolition of individual rights, but to make all rights subordinate to the good of the people. An acceptable definition of either has never been presented, and members of both parties differ materially. Socialism, however, has grown very rapidly, and the Socialistic Party in the United States is frequently successful. Some of our ablest scholars and investigators believe that Socialism will become prevalent, and that in it is vested many of the solutions to our economic problems.
