Revolutions of 1848 carried out, occurred in Greater Poland. Next, the middle classes began to agitate. Karl Marx and Friedrich Engels, working in Brussels, had written "Manifesto of the Communist Party" (published in German in London on February 21, 1848) at the request of the Communist League (an organization consisting principally of German workers). Following the March insurrection in Berlin, they began agitating in Germany. They issued their "Demands of the Communist Party in Germany" from Paris in March; the pamphlet urged unification of Germany, universal suffrage, abolition of feudal duties, and similar middle-class goals. The middle and working classes thus shared a
Center for Economic and Social Justice and series of approaches by which people can understand and practice the moral values, central principles and logic behind a free enterprise theory of economic and social justice.” Its approach is based on a synthesis of the social doctrine of Pope Pius XI as analyzed by CESJ co-founder the late Reverend William J. Ferree, S.M., Ph.D., detailed in The Act of Social Justice (1943) and Introduction to Social Justice (1948), and the economic justice principles developed by lawyer-economist Louis O. Kelso and Aristotelian philosopher Mortimer J. Adler in their two books, "The Capitalist Manifesto" (1958) and "The New Capitalists" (1961).
